The lift shut switch 48 disconnects the cut-off clutch via the ECU when it detects that the pre-processing section 2 has been raised to a predetermined height by the lift potentiometer at the time of the shearing tread operation, When the lift shut switch 48 is turned ON, it is possible to carry out cutting of the next stroke after finishing the cutting of the grain of one stroke. The driving of the preprocessing section 2 is automatically stopped when the preprocessing section 2 is raised and thereafter the swinging or traveling of the gas is carried out so that the generation of driving vibration and noise of the preprocessing section 2 is prevented do.

The direction automatic switch 50 is a switch for turning ON / OFF the automatic direction control. The automatic direction control is a function for detecting the passing position of the central divider with respect to the ground of the cut crop by the direction sensor, The ECU interrupts the side clutch and controls the traveling direction of the gas so that the central divider passes through the center of the tank. The threshing depth automatic switch 52 is a switch for turning ON / OFF the automatic threshing depth control. The automatic threshing depth control is a method for detecting the longest end of the gap between sensors by a sensor provided in the midst of conveyance of the curtain, The ECU controls the thrash depth conveying apparatus by operating the motor up and down so that the threshing depth of the supplied curtain becomes appropriate.

A horizontal manual lever 54 serving as an operating tool for tilting the gas, a horizontal dial 55, a horizontal automatic switch 56 and a horizontal automatic control state are provided on the left side of the switch case 42 A LED lamp 57 is provided. Of these, the horizontal manual lever 54 is constituted by a cross lever switch which can be freely moved forward and backward and left and right, and when the horizontal manual lever 54 is operated to the left or right, the ECU makes a left- When the manual lever 54 is operated forward or backward, the ECU makes the gas inclined forward or backward.

The horizontal automatic switch 56 is constituted by a tactile switch and turns the left and right horizontal automatic control ON and OFF each time the horizontal automatic switch 56 is pressed and turns the front and rear horizontal automatic control ON and OFF. The horizontal dial 55 operates the momentary type switch and the volume and when the dial 55 is depressed, the switch is turned on and the gas frame 3 and the traveling part 8 ) Is returned to a position where the track frame is parallel (front-rear horizontal reset). Further, when the volume is rotated by the horizontal dial 55, the rotation angle of the volume is set as the target tilt angle in the horizontal left automatic control. Incidentally, the central operating position of the horizontal dial 55 is a position for absolutely horizontally controlling the base.

A cut-off height dial 61, which is an operating tool for setting the lowering position of the pre-processing section 2, is provided on the left rear side of the switch case 42. The cut height dial 61 activates the volume, and its rotation angle becomes the set value of the descent position of the pre-processing section 2. [ Further, if the cutting height dial 61 is turned further than the minimum, the setting of the descent position of the preprocessing section 2 is canceled. When the setting of the descent position of the preprocessing unit 2 is released, the ECU operates the hydraulic lift cylinder by the forward and backward movement of the multi-steering lever 38 to freely elevate and lower the pretreatment unit 2. [

However, when the lowering position of the pre-processing section 2 is being set, the ECU compares the value of the lift potentiometer for detecting the lift-up position of the preloading section B with the set value of which is set by the cutting height dial 61, The lowering operation of the hydraulic lift cylinder 5 is stopped and the lowering of the preprocessing section 2 is stopped. Further, in this state, when the setting value is changed by operating the cut height dial 61, the ECU follows the set value and performs the elevation of the pre-processing section 2. [

The main speed change lever 62 and the auxiliary speed change lever 63 are provided as operating tools for shifting the vehicle. The main speed change lever 62 is inserted into the guide groove 64 having the neutral (stop) lateral groove 64a, the forward side vertical groove 64b and the reverse side vertical groove 64c, And a grip 62a at an upper end thereof. The servo valve of the constant-hydraulic-pressure step-variable transmission HST for traveling is switched by the forward and backward movement of the main speed-change lever 62, Reverse switching and continuously-variable shifting.

The main speed change lever 62 also has a forward and backward rotation operating region (a region of the guide groove 64 extending from the forward side and the reverse side) so as to be easily operable even when operated from the driver's seat 31 In the embodiment, the neutral groove 64a is arranged so as to be located forward of the front end of the seat surface of the driver's seat 9 in the embodiment.

The auxiliary speed change lever 63 is provided on the inside of the base of the advancing side guide groove 64b of the main speed change lever 62 so as to be capable of pivoting forward and backward and the auxiliary shift lever 63 is held by the grip 63a When the operation is performed back and forth along the guide groove 65a, the gear-type auxiliary transmission provided in the transmission case is mechanically switched to neutral, low speed, standard (medium speed), and traveling (high speed). When the auxiliary shift lever 63 is operated from the low speed change position to the left side and operated to the left end of the lateral groove 65b, the turning force switching device provided in the transmission case is mechanically switched to the spindle turn. Further, a combination switch 66 is provided at the rear of the auxiliary shift lever 63. [ The combination switch 66 includes a lighting switch, a flasher switch, and a horn switch.

On the rear side of the main speed change lever 62, a second group of operating tools is provided. The second operating tool group includes a turning mode setting dial 67, a pulling air amount setting dial 68, a discriminating dial 69 and a DPF switch 70, 71 are arranged in the forward and backward directions. Of these, the turning mode setting dial 67 rotates the volume, and the ECU switches to the brake turn mode, the deceleration turn mode, or the full mode turn mode depending on the rotation angle of the volume, The adjustment pressure of the turning force in the mode turn is set.

That is, the rotary force conversion apparatus provided in the transmission case 37, on the basis of the control of the ECU, the side with the brake turned to clutch the brake driving unit 8, which is broken turning the inside, that is the side clutch is disconnected turning inside A deceleration turn for decelerating the traveling section 8 to drive in the same direction as the traveling section 8 on the outside, a pull mode turn for continuously performing deceleration and brake turns, and a traveling section 8) in the opposite direction.

Therefore, when the turning mode setting dial 67 is rotated as far as the brake turn side or the deceleration turn side, the ECU is in a mode for switching the turning force changing apparatus to the brake turn or the deceleration turn. Mode to the full-mode turn. Further, when the negative speed change lever 63 is operated from the low speed change position to the left, the ECU detects this by the switch and switches to the spun turn. In each of the turning modes, the timing at which the turning force switching device is actually switched is determined by the hardness angle of the multi-steering lever 38 in the left-right direction.

Further, the current air volume setting dial 68 operates the volume, and the air volume of the pull fan of the threshing section 3 is set by the rotation angle of the volume. Then, when the air flow rate of the current fan is set, the ECU changes the opening degree of the split pulley of the belt continuously variable transmission by the motor, and controls so as to obtain the set air flow rate. Further, the selection dial 69 operates the momentary type switch and the volume, the switch is turned on every time the dial 69 is pressed, and the automatic selection control is turned ON / OFF, and the automatic control state is displayed The LED lamp 72 is turned on or off. When the volume is rotated by the dial 69, material conditions such as rice and barley in the automatic sorting control are set. The DPF switch 70 is constituted by a momentary type switch, and when the DPF switch 70 is turned on, the aforementioned DPF regeneration is performed.

In the following, a description will be given of the operation of the operator during the cutting and treading operation. When the operator performs the operation of each part of the body while sitting on the driver's seat 9 Of course. However, it is also possible to perform the operation of lifting and lowering the pretreatment unit 2 at the time of cutting the web, the forward / backward operation of the gantry at the time of rotation cutting, the direction adjustment operation of the gantry at the time of joining or cutting, The operator often stands up from the driver's seat 9 in order to perform these operations quickly and accurately.

In addition, it is also possible to cope with the settlement height of the running section 8 depending on the hardness and softness of the fields, or the height of the cutting height based on the inclination of the gas, The operator is required to stand up from the driver's seat 9 and respond quickly and appropriately by operating the operating tool while confirming the state of the field of rice or the state of the cutting material in front of the gas.

That is, at the time of the cutting and shearing operation, adjustment of the cutting height by the inclination of the base (horizontal manual lever 54) or the change of the cutting height setting value (cutting height dial 55) (Lift shut switch 48) of the pre-loading section 3 accompanied with the ridge bale raising operation, the adjustment of the threshing depth by the automatic threshing depth automatic switch 52, (Automatic direction switch (50)) of the direction automatic control accompanying the cutting, adjustment of the engine speed by increasing or decreasing the engine load (engine rotation automatic dial (47)), (Power clutch switch 44) of the take-off clutch is required.

Therefore, in order for the operator to stand up from the driver's seat 9 and to respond quickly and appropriately by operating the operating tool while looking at the state of the field of the field, the state of cutting material, It is preferable that the tool is located at the front of the operator and in a position where the hand is instantly accessible. Here, the present invention determines the placement of the manipulation tool from the relevant ergonomic standpoint. In addition, depending on the function of the operating tool, the operating frequency naturally varies between high and low. Here, in the present invention, when the combine is handled, the position of the placement is determined based on the frequency of operation of the operation tool during the workpiece scraping operation, with the target of the scraping operation being the first long time operation being the target.

Specifically, the first manipulation tool group and the second manipulation tool group are divided based on the operation frequency of the manipulation tool. A first operating tool group having a high frequency of operation to be used during the cutting operation is arranged on the front side of the driver's seat 9. Thus, when the operator is standing up from the driver's seat 9 and watching forward, the first operating tool group is positioned in front of the operator and the multi-steering lever 38 is held with the right hand, It is possible to extend the left hand to the operating tool of the first operating tool group and to operate it, so that quick response is possible.

Further, an operation tool (main speed change lever 62, auxiliary speed change lever 63) for performing shifting of the vehicle body is disposed behind the first group of operating tools. As a result, even when the operator is away from the driver's seat 9, it is possible to perform the forward / backward operation of the vehicle or the moving speed in the field (medium speed or high speed). A second operating tool group having a low operating frequency is arranged behind the operating tool for performing the gear shift of the base. It is preferable that the second operating tool group is operated only once at the start or after the completion of the cutting operation, and it is rarely necessary to operate the working tool during the machining operation (the turning mode setting dial 67, Dial 68, selector dial 69, and DPF switch 70), it is sufficient that the operator can calmly operate while sitting on the driver's seat 9.

When the second group of manipulation tools is added to the first group of manipulation tools, the number of manipulation tools of the first manipulation tool group must be increased and the installation space of the first manipulation tool group must be increased. (The main speed change lever 62 and the auxiliary speed change lever 63) for performing the shift change of the vehicle. However, this can be solved by dividing by the second group of manipulation tools and limiting the number of manipulation tools of the first group of manipulation tools to the minimum necessary. In addition, since the number of operating tools of the first operating tool group is small and the operating tools are not mixed together as in the case of adding both, it is possible to select the necessary operating tool without mistakes and improve the accuracy of shearing accuracy .

The present invention also considers the arrangement of the respective operation tools in the first group of operation tools. That is, even in the operating tool of the first operating tool group, there is a difference in the frequency of operation naturally high and low. For example, intermittent operation of the cutting clutch and the threshing clutch is required before and after the cutting operation or before or after the traveling in the field. In addition, when the intermittent operation of the cut-off clutch and the thresh-up clutch is performed, the engine speed is changed to a high speed necessary for the shearing-treading work, or the speed is changed to a suitable speed for traveling, , An idling state, and the like. These operations are more frequently performed than the other operations.

Therefore, an operation tool (power clutch switch 44) for interrupting the cut-off clutch and the descending clutch having a high operation frequency among the first operating tool group, an operation tool (engine rotation automatic dial 46) Is disposed on the rightmost side of the switch case 42 for providing the first group of manipulation tools. Therefore, these manipulation tools are located closest to the driver's seat 31, and the operator standing on the driver's seat 31 can quickly operate the driver's seat with his left hand. In addition, since the operation timings of these operation tools are substantially in the fore-and-aft direction, it is possible to perform the transition to the other operation tool in an extremely short time after operating one of the operation tools and to reduce operator fatigue even if the operation frequency is high So that the work efficiency can be improved.

When clogging or the like occurs in the preprocessing section 2 or the threshing section 3 during the shearing operation, the operator operates the power tool clutch switch 44 for interrupting the shearing clutch and the descending clutch, (B) and the threshing section (C) can be stopped, thereby preventing occurrence of serious clogging. In addition, since the operation tool (engine rotation automatic dial 46) for setting the engine rotation speed is provided nearest to the liquid crystal display part 14, the engine rotation speed displayed on the liquid crystal display part 14 can be set in the field of view It is possible to quickly set the engine speed by the engine speed and increase or decrease the engine speed based on the engine load ratio similarly displayed on the liquid crystal display unit 14 and to efficiently perform the shredding work in the engine load state with margin .

The operating frequency of the first operating tool group excluding the operating tool (power clutch switch 44) for interrupting the cutting clutch and the threshing clutch and the operating tool for setting the engine speed (engine rotating automatic dial 46) , There is a difference between mutual manipulation tools when examined in detail, but the difference is not so great. Therefore, in this case, the relevance (vowel) based on the function of the operation tool is considered first, and the arrangement environment of the operation tool is determined by comprehensively determining the surrounding environment, operability, and the like.

That is, from the first viewpoint, the horizontal manual lever 54, the horizontal dial 55, the horizontal automatic switch 56, and the LED lamp 57, which indicates the horizontal automatic control state, . In addition, the switches that perform only the ON / OFF control of the automatic control are arranged in the same area or in close proximity to each other. From the second point of view, the first group of operating tools is a group of the first operating tool that is capable of changing the operating tool (main shift lever 62, auxiliary shift lever 63) . Here, the arrangement is such that the operability of the operation tool is not hurt even if the shadow is spanned.

More specifically, a lift shut switch 48, an LED lamp 49 for indicating the state thereof, a directional automatic switch 50, a threshing depth automatic switch 52, and an LED lamp (not shown) 51, and 53 are switches for performing only ON / OFF control of automatic control, they are collectively arranged. Further, the switches 48, 50, and 52 for turning ON / OFF the automatic control do not need an operation space because they perform the ON / OFF operation of the automatic control by the finger touch operation.

Both of these switches 48, 50 and 52 are constituted by a tactile switch, the protruding amount of the switch from the resin sheet 43 provided on the surface of the switch case 42 is small, Even when the main speed change lever 62 is operated to the maximum advancing side and the operator sees the grip side of the grip 62a, the operation space in the up-and-down direction Is provided on the center side of the switch case (42) in front of the main speed change lever (62), since it does not interfere with the operation. The main speed change lever 62 is operated to the maximum forward side and an empty space S is provided immediately below the grip 62a on the shadow side of the grip 62a as seen by the operator, Or the like.

Since the horizontal manual lever 54 is constituted by a cross lever switch and the amount of projection of the lever 54 from the switch case 42 is large and a wide operating space for lever operation is required, Is provided on the left side of the switch case 42 which is farthest from the operating tool (main shift lever 62, auxiliary shift lever 63) for performing the shift of the automatic transmission 3. The horizontal automatic switch 56 is provided in the same area as the horizontal manual lever 54 because it does not require a lot of operation space with a switch for turning on and off the automatic control, And is provided on the right side of the horizontal manual lever 54 which is in front of the main speed change lever 62. [ An LED lamp 57 for indicating a horizontal automatic control state attached to the horizontal automatic switch 56 is also provided close to the horizontal automatic switch 56. [ The remaining horizontal dial 55 is provided at the rear of the horizontal manual lever 54.

The last cut-off height dial 61 is provided at the rear of the switch case 42 on the left side. The horizontal dial 55 and the cut height dial 61 require a large operating space for holding and operating the dial and also protrude somewhat from the switch case 42. Therefore, So that the operability thereof is ensured. These dials 55 and 61 are provided on the front side of the negative speed change lever 63. The speed change stage in which the negative speed change lever 63 is tilted to the maximum forward direction is a running (high speed) Thus, there is little problem that the auxiliary shift lever 63 is shifted to the running end during the shearing work and that these dials 55 and 61 are provided on the front side of the auxiliary shift lever 63. [

The arrangement of the operating tools of the first operating tool group is as described above. However, when the type of operating tool of the first operating tool group or the number of operating tools is changed in accordance with the specifications and format of the combine 1 . That is, in the example shown in Fig. 17, only the left-right tilt control is performed for the tilt control of the base, and the backward-tilt control is not performed. . Further, the horizontal automatic switch 56 allows only ON / OFF of the left and right horizontal control, and the number of the LED lamps 57 decreases. Further, the horizontal dial 55 merely rotates the volume, and the switch is turned off.

The example shown in Fig. 18 eliminates the control related to the inclination control of the base and includes a horizontal manual lever 54, a horizontal dial 55, a horizontal automatic switch 56, and an LED lamp 57 ). The example shown in Fig. 19 shows the arrangement of the first group of manipulating tools in the universal combine. In this case, only the right-left inclination control is performed to control the inclination of the base body, and the forward and backward inclination control is not performed. Further, by operating the horizontal manual lever 54 in the forward and backward directions, the right and left sides of the gas can be simultaneously raised or lowered.

Further, the horizontal automatic switch 56 can be switched to left / right horizontal control or ground / balance control. Also, in the earth balance control, a slide sensor is provided below a header part constituting the preprocessing part 2, and left and right tilt control is performed by the slide sensor so that the left and right sides of the header part are parallel to the ground surface. Instead of the horizontal dial 55, a reel rotation dial 73 and an LED lamp 74 for indicating the ON / OFF state of automatic control are provided. The reel rotation dial (73) activates the momentary type switch and the volume, and the switch is turned on each time the dial (73) is pressed, and automatic reel rotation control is turned on and off. When the volume is rotated by the dial 73, the number of reel revolutions corresponding to the rotation angle is set.

The reel rotation automatic control is for automatically controlling the rotation speed of the rake reel provided in the header portion to be synchronized with the vehicle speed and the rotation number of the rake reel is adjusted by the reel rotation dial 73 It is possible. Since the automatic directional control and the automatic thrash depth control are not performed, instead of eliminating the automatic directional switch 50 and the automatic threshing depth switch 52, And an LED lamp 76 for indicating an ON OFF state is provided. Further, the automatic cutting edge height control automatically elevates and lowers the header portion based on the detection value of the slide sensor, and controls the cutting height of the material.

The display control section 24 can switch the display screen of the liquid crystal display section 14 to the simple display screen D for enlarging and displaying the basic information group a in accordance with an artificial screen switching operation, , The visibility of the basic information (a) can be improved at the time of non-work traveling which does not require the accessory information (b).

The display control unit 24 displays the display screen of the liquid crystal display unit 14 on the second camera image display screen E And the second camera image display screen E switches the camera image to another camera image while maintaining the display of the basic information group (a), so that it is possible to switch, for example, The back camera image for confirmation and the auger camera image for adjusting the discharge position mounted on the auger discharge port can be switched and displayed as necessary.

The display control section 24 switches the display screen of the liquid crystal display section 14 from the camera image display screen C to the camera image enlargement display screen F for enlarging and displaying the camera image in accordance with an artificial screen switching operation In the camera image enlargement display screen (F), the display area of the basic information group (a) is reduced or omitted to enlarge and display the camera image. Thus, for example, Or the auger camera image is enlarged, so that the accuracy of the discharge position adjustment can be enhanced.

When the basic information display area bb of the camera image display screen CC is tapped, the basic information group is switched to the simple display screen BB to be enlarged. When the simple display screen BB is tapped again , And returns to the camera image display screen (CC). When the camera image display area dd of the camera image display screen CC is tapped, the camera image is switched to the camera image enlargement display screen DD to be enlarged and displayed, and the camera image enlargement display screen DD Return operation area) is tapped again, the screen returns to the camera image display screen (CC).

Next, display operations (initial display, abnormal display, dealer menu display, and error history display) of the liquid crystal display section 14 will be described with reference to Figs. 27 to 31. Fig.

The liquid crystal display unit 14 displays the detailed display screen AA, the simple display screen BB and the camera image display screen CC in a state in which the operation screen is switchable, The work screen displayed last at the time of the previous conference operation is displayed as the initial screen. For example, when the key switch SW is turned OFF while the camera image display screen CC is displayed, when the next key switch SW is turned ON, the camera image display screen CC is displayed on the initial screen . In the present embodiment, when the key switch SW is turned OFF while the camera image enlargement display screen DD is displayed, when the next key switch SW is turned ON, the camera image display screen CC Is displayed as the initial screen, the camera image enlargement display screen DD may be displayed as the initial screen.

When the key switch SW is turned off in the state that the setting screen EE is displayed on the liquid crystal display unit 14, when the next key switch SW is turned ON, not the setting screen EE, And displays the work screen displayed last at the time of previous meeting as an initial screen. For example, from the detailed display screen AA to the setting screen EE, when the key switch SW is turned OFF in the display state of the setting screen EE, the next key switch SW is turned ON When operated, the detail display screen AA is displayed as an initial screen.

27 and 28, the liquid crystal display section 14 performs an abnormality notification indicating an abnormal state of the gas. The items to be notified include an alarm item for which an alarm is issued in accordance with the occurrence of the abnormality and an engine stop item for stopping the engine in response to the occurrence of the abnormality. For example, alarm items include engine overload alarm, engine oil shortage alarm, battery voltage error alarm, selection overload alarm, 1st spiral, 2nd spiral overload alarm, air cleaner abnormal alarm, DPF alarm, engine coolant temperature abnormal alarm, Knotter strap drop alarm and grain tank full alarm. Examples of engine stop items are pre-processing blockage, 1st spiral, 2nd spiral clogging, exhaust straw clogging, clogging of binding, grain tank overflow, engine Stop switch operation.

As shown in Fig. 27, the abnormality notification relating to the alarm item is displayed by a pop-up window overlapping with the displayed screen. For example, the abnormality notification relating to the alarm item shown in Fig. 27 is an alarm of battery voltage abnormality, and a message " Battery is insufficient to charge " Please give me a message. " Incidentally, it is preferable to select a color that is capable of drawing attention such as " yellow " in the background of the abnormality notification screen concerning the alarm item.

As shown in Figs. 20 to 23 and Fig. 27, the abnormality related to the alarm item can be switched between the enlarged display and the reduced display corresponding to the artificial operation. In other words, although the alarm at the beginning of the display of the abnormal alarm warns the operator of the abnormal state in the enlarged display shown in Fig. 27, since the abnormal state relating to the alarm item can be continued even if the alarm condition occurs, , It is possible to prioritize the display of the work screen by making the abnormality notification a reduced display. In the present embodiment, when the abnormal display area shown in Fig. 27 is tapped, the abnormal display is displayed at the lower part of the screen as shown in Fig. 20 to Fig. In the reduced display, the countermeasure against the abnormality is not displayed but only the abnormality is displayed. Further, when the reduced display area is tapped, the expanded abnormal display shown in Fig. 27 is switched. Incidentally, when the abnormality display is reduced and displayed, the effect of ventilation of the state is lowered. Therefore, it is preferable to select "red" or the like with a higher ventilation effect than "yellow" as the background of the reduced abnormality display.

As shown in Fig. 28, the abnormal display relating to the engine stop item is displayed as a full screen by switching the screen during display. For example, the abnormality notification relating to the engine stop item shown in Fig. 28 is a message indicating that the preprocessing section is clogged, and the message " pre-processing section clogging " "And" this screen does not disappear unless the problem is solved "is included. Incidentally, it is preferable that the background of the abnormality notification screen related to the engine stop item is "red" which has a higher ventilation effect than "yellow" (the background color of the enlargement / anomaly display related to the alarm item).

In the abnormal display of the engine stop item, the display switching is not possible in response to the artificial operation, and the display continues until the cause of the abnormality is resolved. On the other hand, the abnormal display regarding the alarm item can be switched to the reduced display corresponding to the artificial operation, and the operation can be continued in this state. However, the abnormal display (including the enlarged display and the reduced display) ), The display continues until the cause of the problem is solved, so that it is possible to promote a reliable response to the abnormality.

In a situation where a plurality of anomalous items occur, it is impossible to simultaneously execute these anomalous notifications, so that priority is given in advance. For example, the abnormality of the engine stop item is given priority over the alarm item, the priority order is set for the plurality of abnormal types included in the engine stop item, and also, for the plurality of abnormal types included in the alarm item, . When a plurality of anomalous items occur, anomalous display is performed from an item having a higher priority in accordance with a predetermined priority order.

As shown in Fig. 29, the liquid crystal display unit 14 can display a dealer menu screen (FF) mainly used by a dealer's service man. The transition to the dealer menu screen FF is performed by, for example, performing an operation of pressing one or a plurality of predetermined touch operation buttons 25a to 25e on the setting screen EE for a long time.

As shown in Fig. 30, in the dealer menu screen FF, "input check", "history" and "return" are added as button names of the touch operation buttons 25a, 25b and 25e, respectively. When the touch operation button 25a is tapped, an input check screen (not shown) is displayed. When the touch operation button 25b is tapped, the error history screen GG shown in Fig. 19 is displayed. 25e are tapped, the screen returns to the setting screen EE. Incidentally, the input check screen is a screen for checking a signal input of a sensor or the like. When a normal signal is inputted to the display control section 24, for example, in accordance with an operation of a component to be checked, . In the present embodiment, the input check screen is treated as a special mode. The special mode means a control state in which, once the transition is made, returning to the previous screen is regulated, and the screen display is maintained until the engine stops.

31, in the error history screen GG, an error history number (for example, an error history 01), an error occurrence time (for example, an hour meter 8888.8) , A plurality of error histories, which are specified by the pre-processing clogging (engine stop), are displayed in a time-sequential order in the vertical direction. The error history displayed on the error history screen GG includes error information on abnormality of the electrical component stored as the electrical component system error history and error information on the abnormality of the gaseous state stored as the gaseous state error history And the history of the electrical part system error history and the gaseous state error history are displayed in a time series in a one-dimensional manner. According to such an error history display, it is possible to determine the cause of the electric component part system error based on the previous gas state system error history. For example, if a pretreatment lift potentiometer error occurs after two pretreatment clogs, it is considered to be an abnormality of the pretreatment lift potentiometer due to the clogging of the pretreatment, so that not only the pretreatment lift potentiometer is simply replaced, It can be understood that it is necessary to check whether or not the periphery thereof is damaged.

31 shows the clogging of the engine stop error items and the clogging of the pre-processing closure, in which the engine is stopped in response to the occurrence of an error, as an item of the gaseous system error indicated as the gaseous state error history, Needless to say, items are included. The gaseous state error indicated as the gaseous state error history may also include the above-mentioned alarm error item for generating an alarm in response to the occurrence of an error. This makes it possible to estimate that there is a cause for the use of the machine by the operator when, for example, the transmission belt is broken and replaced, and the selection history or the spiral overload warning history remains as the error history.

In the error history screen GG, it is preferable to make the display color of the error history different according to the type of error. For example, the electric component part error history is indicated as "yellow" and the gas state error history is indicated as "red". In this manner, the type of error can be identified based on the display color, thereby facilitating the search for the cause of the error.

Next, the control procedure of the display control section 24 for realizing the screen switching operation and the display operation of the liquid crystal display section 14 as described above will be described with reference to Figs. 32 to 35. Fig.

The display control section 24 is provided with an initial display control means, an enlarged display means, an abnormality notification means, and an error history display means, which are realized by cooperation between hardware and software. A detailed description will be given of an initial display control for realizing the enlarged display means, a screen display switching control for realizing the enlarged display means, an abnormality notification control for realizing the abnormality notification means and an error history display control for realizing the error history display means.

As shown in Fig. 32, in the initial display control, first, it is judged whether the engine is in the stop state or not (S11), the ON operation of the key switch SW is judged (S12) If all are YES, the presence or absence of a storage screen is determined (S13). If the determination result is NO, a predetermined default operation screen (for example, a detailed display screen) among the detailed display screen A, the simple display screen B, and the camera image display screen C, (S14). If it is determined that there is a storage screen, the stored operation screen is displayed on the liquid crystal display unit 14 (S15). Subsequently, after executing the subroutine such as the screen display switching control (S16), the abnormality notification control (S17), and the error history display control (S18), it is determined whether the current display screen is a work screen or other screen (S19). If it is determined that the work screen is the work screen, the type of the work screen currently displayed is rewritten (S205), and if it is determined that the work screen is not the work screen, . Thus, when the key switch SW is turned ON, it is possible to display the work screen finally displayed at the previous meeting work as an initial screen.

As shown in Fig. 33, in the screen display switching control, the operation of the physical operation buttons 26a to 26e and the touch operation (tap operation and flick operation) of the liquid crystal display section 14 are determined (S31, S33, S40). If it is determined that the physical operation buttons 26a to 26e have been operated, a screen corresponding to the operated physical operation buttons 26a to 26e is displayed on the liquid crystal display unit 14 (S32). If it is determined that the tab operation has been performed by the touch operation buttons 25a to 25e (S34), whether or not the tab operation is the enlargement operation valid region (S35) (S36). If it is determined that the tab operation position is the touch operation buttons 25a to 25e, the screen corresponding to the touched touch operation buttons 25a to 25e is displayed on the liquid crystal display unit 14 (S37) If it is determined that the position is the enlargement operation valid area, the screen corresponding to the tab operation enlargement operation valid area is displayed on the liquid crystal display part 14 (S38). If it is determined that the tab operation position is the enlargement operation effective area (Step S39), the screen corresponding to the tab-operated enlarged return operation valid area is displayed on the liquid crystal display part 14. [ If it is determined that the flick operation is in the flick operation effective area (S41). If the result of the determination is YES, the flick operation is performed in the flick operation effective area And causes the liquid crystal display unit 14 to display a screen corresponding to the flick operation direction (S42).

As shown in Fig. 34, in the abnormality notification control, first, it is judged whether or not an abnormal state has occurred (S51). If the judgment result is NO, the abnormality display is cleared (S52) Quot; 0 " (enlarged display) which is the initial value is set to the flag F for switching the enlargement / reduction (S53). On the other hand, when it is judged that an abnormal state is occurring, priority order processing is executed (S54). This priority process is a process for extracting an abnormal item to which abnormality display is preferentially performed according to a predetermined priority in a situation where a plurality of abnormal conditions are occurring. Next, it is judged whether or not the extracted abnormal item belongs to "engine stop item" or "alarm item" (S55). If the judgment result is "engine stop item" And displays it on the liquid crystal display part 14 in full screen (S56). On the other hand, when it is judged that the item is an abnormality relating to the "alarm item", the flag F is referred to (S57). If the flag F is found to be "0", the abnormality relating to the abnormality item is displayed on the liquid crystal display part 14 ) As a pop-up window (S58). Thereafter, a tap operation of the enlarged display area is determined (S59). When the determination result is YES, flag F is set to "1" (S60). If the determination result of step S57 is " 1 ", the liquid crystal display unit 14 causes the liquid crystal display unit 14 to display the abnormal display related to the abnormal item (S61). Thereafter, a tap operation of the reduced display area is determined (S62). When the determination result is YES, flag F is set to " 0 " (S63).

As shown in Fig. 35, in the error history display control, first, the electrical component part system error history storage process S71 and the gas state system error history storage process S72, which are subroutines, are executed. The electrical component part system error history storage processing is processing for storing the error type in the error history database together with the generation time information (hour meter value) when an error of the electrical component occurs, and the gas state system error history storage processing Is a process in which, when a gaseous error occurs, the error type is stored in the error history database together with the occurrence time information. Next, the display operation of the error history display screen is determined (S73). If the result of the determination is YES, the electric component system error history and the gaseous state error history stored in the error history database are displayed on the liquid crystal display unit 14 In a time series (S74). At this time, the electrical part system error history and the gaseous state error history are displayed in different colors.

According to the second embodiment configured as described above, the display control section 24 displays on the liquid crystal display section 14 a plurality of types of work screens (AA to CC) When the key switch SW is turned ON, the operation screens (AA to CC) that were last displayed at the previous conference operation are displayed on the liquid crystal display section 14, so that after the ON operation of the key switch SW , It is no longer necessary to switch to work screens (AA to CC) desired one by one.

A plurality of kinds of work screens AA to CC are provided with a simple display screen BB (first operation screen), a detailed display screen AA (second operation screen), a camera image display screen CC The simple display screen BB displays basic information with high importance and the detailed display screen AA displays basic information and accessory information having lower importance than the basic information, Since the camera image display screen (CC) displays the basic information and the image of the camera installed in the base, it is possible to maintain the display of the basic information with high importance even if any work screen (AA to CC) It is possible to prevent the work from being hindered.

The display control unit 24 of the present embodiment is configured to perform the transition from each of the work screens AA to CC to the setting screen EE and the transition from the setting screen EE to each of the work screens AA to CC When the key switch SW is turned off in the state that the setting screen EE is displayed on the liquid crystal display unit 14 and when the next key switch SW is turned on, , The work screens AA to CC last displayed at the previous meeting work are displayed on the liquid crystal display unit 14 so that the desired work screens AA to CC are selected one by one from the setting screen EE after the ON operation of the key switch SW, CC) becomes unnecessary.
