Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for monitoring the state of a target device, and more particularly to a monitor device for a plurality of devices.

2. Description of the Related Art In various industrial fields, it is necessary to monitor the status of multiple target devices. For example, in a machine tool, a moving device of at least two axes is necessary to change the relative position of one cutting tool and a workpiece in one plane, and one machine tool requires five or six axes. It is not uncommon for mobile devices to be required. Then, in order to grasp the working state of the entire machine tool, it is necessary to monitor the states of these plural moving devices.

Therefore, it has been widely practiced to incorporate a monitor device into a control panel of a machine tool. Most commonly,
A dedicated display unit is provided for each moving device, and the state of the entire machine tool is monitored by displaying the state of each moving device on each display unit. As the number increases, so does the number of displays, which increases cost and is undesired because the monitor occupies a large amount of space on the control board.

Therefore, an integrated monitor device that can use the same display device for a plurality of mobile devices is commercially available. This monitor device
It itself comprises means for selecting mobile devices. Each time the selection switch is operated by the operator, the switch output signal is supplied to the external control device, and one of the plurality of moving devices is cyclically selected by the selection means of the control device. The same selecting means is also operated inside the monitor device to change the selection, and the common display is adapted to display the state of the currently selected mobile device.

In general, the monitor device not only allows an external control device to make a selection change when the selection change of the target device is made by operating the selection switch of the monitor device, but the selection change of the target device is not made in the external control device. When this is done, it is necessary that the selection of the target device be changed in the monitor device in response to the selection change.

Even in the commercially available monitor device, when the selection change is made in the external control device, the selection change is made also in the monitor device. The output signal is exactly the same as the switch output signal supplied to the external control device when the selection switch is operated in the monitor device. One pulse signal is supplied to the monitor device each time the selection of the mobile device is sequentially changed in the control device.

However, in the external control device, the selection change of the target device is not performed cyclically in a fixed order but is often performed randomly.

For example, when the current value of the cutting tool correction amount in the numerically controlled machine tool is monitored by the monitoring device, the dimensions of each part of the product after machining are automatically measured, and the cutting tool wears in a certain direction due to wear of the cutting tool. When it is determined that it is necessary to correct the position, the position of the cutting tool in that direction is corrected, and in such a case, it is common that the order of selecting the plurality of moving devices, which are target devices, is random. That is why.

However, in the above-mentioned commercially available device, since the signal supplied from the external control device to the monitor device is as described above, for example, in the control device, the No. 1 moving device is selected as the No. 4 moving device. Is changed, it is necessary for the control device to supply three pulse signals to the monitor device, and it is necessary to supply a different number of pulse signals for each different mode of selection change. Moreover, the processing in the control device becomes troublesome.

Such a problem widely occurs not only in a monitor for machine tools but also in a general integrated monitor.

In view of such circumstances, the present invention makes it possible to use the same display as a monitor for a plurality of target devices, and even if the target device is selected and changed by an external control device, the process in the control device is performed. It is an object of the present invention to provide an integrated monitor device that does not become a hassle.

Means for Solving the Problems In order to solve the above problems, the present invention provides an integrated monitor device, (a) one output terminal and (b) one output terminal for each output terminal operated by an operator. (C) a plurality of selection input terminals to which selection signals corresponding to the target device selected by the external control device in response to the switch output signal are input, respectively. ) A selected target device display for displaying the currently selected target device based on the selection signal to the selection input terminals, and (e) input of relevant information related to each of the target devices from an external control device. At least 1
(F) A related information creator that creates other related information based on the related information input to the information input terminal, and stores the created previous related information. And (g) at least the other of the present time, which includes a storage unit, and creates the other relevant information of the present time based on the other relevant information of the previous time stored in the storage unit and the related information input this time. And a related information display for displaying related information.

Operation The integrated monitor device configured as described above does not include means for selecting the target device by itself, and outputs one switch output signal to the external control device each time the selection switch is operated. In the control device, the selecting means selects from among the plurality of target devices each time the switch output signal is supplied.
The target device is cyclically selected, and a selection signal is supplied to one of the plurality of selection input terminals of the monitor device that corresponds to the selected target device. In the monitor device, the target device currently selected based on the selection signal is displayed on the selected target device display, and the operator selects the status of the target device selected from this display and the related information display. Can be monitored.

The related information displayed on the related information display unit is the final related information which is another related information created based on the basic related information which is the related information input to the information input terminal by the related information creating unit. It is said that The related information creator stores the created last final related information in the storage unit, and stores the previous final related information stored in the storage unit and the basic related information input this time to the information input terminal. Based on this, the final relevant information of this time is created. That is, the final relevant information is created from the basic relevant information in the monitor device itself, not in the control device or the target device. The signal representing the basic related information may have a smaller amount of information to be transmitted as compared with the signal representing the final related information, and in this case, the basis for connecting the control device and the monitoring device. It is possible to create and display the final relevant information having a large amount of information while reducing the number of signal lines for inputting the relevant relevant information, that is, the number of information input terminals of the monitor device.

Effect of the Invention As is apparent from the above description, in the integrated type monitor device according to the present invention, the related information display can be used for a plurality of target devices, and one selection input terminal is provided for each target device. When the target device is selected and changed by the external control device, the control device selects one of the selection input terminals of the monitor device that corresponds to the selected target device. It suffices that the selection signal is supplied, and the control of the control device does not become troublesome even when the selection change of the target device is performed at random.

Moreover, since the monitor device itself outputs only one switch output signal to the control device each time the selection switch is operated, it is necessary to enable the target device to be selected by operating the monitor device. Since only one output terminal is required, it is not necessary to provide the monitor device itself with means for selecting and changing the target device, and the monitor device can be downsized. Also, the number of wires required for connection with the control device is small, and the device cost can be kept low. Furthermore, since the monitor device itself creates the final related information based on the basic related information, it becomes easy to reduce the number of information input terminals of the monitor device, which also keeps the device cost low. it can.

Next, the operation of the correction amount monitor / change device 8 will be described with reference to the flowcharts of FIGS.

Simultaneously with turning on the power, step S1 in FIG. 5 (hereinafter, simply
It is represented by S1. The same for the other steps)
Initial settings are made. As a result, the mode flag in the work area is reset, the correction amount monitor / change device 8 is set to the operation mode, and the correction number display 1
Numerical values 1 to 6 corresponding to the correction No. selection signals 1 to 6 from the PC 56 are displayed on 2, and the correction current value display 14 and the set value display 16 respectively display the correction No. selection signals 1 to 6. The corrected current value and the corrected increment value of the mobile device corresponding to
It is read from M68 and displayed.

After that, S2 is executed, and the respective flowcharts shown in FIGS. 6 to 9 are repeatedly executed in a time division manner.

In S11 of FIG. 6, it is determined whether the selection signal input to the selection input terminal has changed. correction
Every time the No. selection switch 18 is operated once, one pulse signal is supplied from the correction amount monitor / change device 8 to the PC56, and the counter counts this pulse signal in the PC56. Since the maximum count value of is 5, the possible values of the count value are 0 to 5
No. 1 of NC58 respectively.
6 to 6 of each moving device and correction amount monitor / change device 8
It is associated with the individual input terminals. That is, the selection of the moving device is changed by changing the count value of the counter.
The selection signal is supplied to the six selection input terminals corresponding to the respective count values of the counter. In addition, when it is determined that the cutting tool position needs to be corrected by measuring the size of the work piece with the NC58 automatic measuring machine and the moving device is selected and changed, the correction amount monitor / change device 8 is selected and input. The selection signal supply to the terminals changes. In any case,
If the selection is changed in PC56, the judgment result in S11 is Y
The status becomes ES, and the display of the selection No. indicator 12 is changed to a numerical value corresponding to the currently selected mobile device in S12.

Next, the monitoring process and the setting value changing process will be described based on the flowchart of FIG.

These processes are performed in accordance with the operation of the mode selection switch 20, the digit selection switch 22, the minus correction switch 24 and the plus correction switch 26, and as a result, the display of the correction amount monitor / change device 8 is shown in FIG. To change.

If any switch is operated while S21 is repeatedly executed, S22 is executed to determine whether or not the operated switch is only the mode selection switch 20, and if the result of the determination is YES. For example, in S23, this device is switched to the operation mode. Specifically, the mode flag is reset, but since the mode flag is reset in the initial setting, practically nothing is performed in the first time. Then, in S24, the value of n is 1
Increased and light emitting diodes 30 to 34 in S25
The monitor mode is displayed by, and each set value is displayed on the set value display 16. At first, n is 1 and the monitor mode is set and the correction increment value is displayed. However, since the set value indicator 16 is normally in the state of displaying the correction increment value, the first At the first time, the light emitting diode 30 is only turned on and the display of the set value indicator 16 does not change. Whether or not n is 4 is determined in S26, but initially the determination result is NO, so S27
Returns to the state where S21 is bypassed and S21 is repeatedly executed.

Next, if the mode selection switch 20 is operated, n is 2
Then, the light emitting diode 32 is turned on, and the correction upper limit value is displayed on the set value display 16. When the mode selection switch 20 is operated again, the light emitting diode 34 is turned on and the correction lower limit value is displayed on the set value display 16.

After that, when the mode selection switch 20 is operated again, n becomes 4, the determination result in S26 is YES, n is changed to 0 in S27, and the monitor mode is released. That is, it returns to the original state, and so on.
The display in the monitor mode is sequentially selected according to the operation of the mode selection switch 20.

On the other hand, if the determination result in S22 is NO, in S28, it is determined whether or not the mode selection switch 20 and the digit selection switch 22 have been simultaneously operated. Then, if the determination result is YES, the mode flag is set in S29, and the present apparatus is shifted to the setting mode. At the same time, the continuous operation permission signal that has been output from the correction amount monitoring / changing device 8 to the PC 56 until then is turned off, and based on this, the NC 58 is stopped at the time when the operating cycle being executed at that time ends.

Subsequently, the display is changed in S30. For example, the first
In FIG. 0, when the mode selection switch 20 and the digit selection switch 22 are simultaneously operated in the state where the correction increment value is displayed on the set value display 16, the display of the set value display 16 is shown on the right side. To be changed. That is, the second
All numerical values below the rank are displayed and the numerical value of the second digit (0 in this case) is blinked.

In this way, when the digit selection switch 22, the minus correction switch 24 and the plus correction switch 26 are operated in the state where the setting mode is entered, the determination result of S31 becomes YES through S21, S22 and S28, and S32, It is determined in S33 or S34 which switch is operated, and in S35, S36 or S37, processing corresponding to the operation of each switch is performed. That is, the digit selection switch 22 is 1
If it is operated once, the lower digit is selected one by one, if the plus correction switch 26 is operated once, the value of the selected digit is increased by 1, and if the minus correction switch 24 is operated, it is decreased by 1. To be made. After the least significant digit is selected, the most significant digit is selected and the digits are cyclically changed. This allows the operator to arbitrarily change the set value of the correction increment value, the correction upper limit value, or the correction lower limit value.

If the plus correction switch 26, the minus correction switch 24, etc. are operated as described above, those switch output signals are supplied to the PC56, or the PC56 turns off the continuous operation permission signal.
During this period, the correction command signal is not supplied to the NC 58 and the correction amount monitor / change device 8 based on these switch output signals, so only the set value is changed in the correction amount monitor / change device 8. Therefore, NC58 does not correct the cutting tool position. As a result, the switch output signal from the correction amount monitor / change device 8 when the set value is changed
Since it is not necessary to prevent the signal from being supplied to the PC 56, there is an advantage that the signal processing in the correction amount monitor / change device 8 becomes simple.

If the mode selection switch 20 is operated independently while the correction amount monitor / change device 8 is in the setting mode, S2
3 to S27 are executed to shift to the operation mode, and the set value display mode is changed to the next mode. Also, if the determination result of S21 is YES and the operated switch is other than the above switches,
The judgment results of S22, S28, S32, S33 and S34 are all NO, or the judgment results of S22, S28 and S31 are all NO.
Then, the execution of the program returns to S21 without causing any effect.

If it is necessary to change the selection of the moving device, operate the correction No. selection switch 18 and the PC56
The moving device selection was changed at the
Since the selection signal is input to the changing device 8, the correction amount monitoring / changing device 8 can know which moving device is currently selected by this selection signal. S25, S30, S3
5, the processes of S36, S37 and the like are executed for the set values corresponding to the selected mobile devices.

Next, the correction process will be described based on the flowchart of FIG.

First, in S41, it is determined whether or not the selection signal supplied from the PC 56 to the correction amount monitor / change device 8 is normal. As described above, the correction amount monitor / change device 8
The selection signal must be input to one of the selection input terminals of, and the selection signal should not be input to the two selection input terminals at the same time. However, the selection signal may not be input due to malfunction or failure of PC56. You haven't entered any,
It is possible that multiple selection signals have been input. In such a case, if the correction process is performed, the correction process is likely to be erroneous. Therefore, the determination in S41 is performed so as not to perform the correction process.

If the decision result in S41 is YES, the process from S42 onward is executed, and along with this execution, the signal shown in FIG. 11 is exchanged with the PC 56. When any of the minus correction switch 24, the plus correction switch 26, and the correction value reset switch 28 is operated, the output signals of those switches are supplied from the correction amount monitor / change device 8 as shown in FIG. 11 (a). To be done. In response to this signal, the relay in the PC 56 is set in the self-holding state in FIG. 11 (b). as a result,
A correction command signal is output from the PC 56 to the NC 58 as shown in FIG. 11 (c), and a correction command is also issued to the correction amount monitor / change device 8 as shown in FIG. 11 (e). A signal is issued. Correction is executed in the NC 58 and the correction amount monitor / change device 8 according to the correction command signals, and when the correction is completed, a completion signal is supplied to the PC 56 as shown in FIGS. 11 (d) and 11 (f). Then, the self-holding of the relay of PC56 is released accordingly, and the correction command signal to the correction amount monitor / change device 8 and NC58 is turned off.
As a result, the completion signal issued from both devices
Turned off. Every time any one of the minus correction switch 24, the plus correction switch 26, and the correction value reset switch 28 is operated, the above-mentioned exchange of signals is repeated.

The processing in the correction amount monitoring / changing device 8 associated with the transmission / reception of this signal will be described below. In S42, the correction command signal from the PC 56 is waited, and if the correction command signal is received, it is determined in S43 whether or not the operation mode is set. If the result of the determination is YES, S44 and thereafter are executed. The correction process is not performed in the setting mode.

By executing S44, the light emitting diode 48 is turned on, and as shown in FIG. 12, a correction process corresponding to the operated switch is performed. If the plus correction switch 26 is operated, the correction increment value is added to the correction current value of the RAM 68 to increase the correction current value, and the display of the correction current value display 14 is changed. When the correction switch 24 is operated, the correction current value is reduced by the correction increment value, and when the correction value reset switch 28 is operated, the correction current value is reset.

When the above correction processing is completed, a completion signal is output to the PC 56 in S45, and it is waited for the correction command signal from the PC 56 to be turned off by repeating S46, and the completion signal is turned off in S47.

Then, in S48, the changed corrected current value is stored in the RAM68.
The correction limit value stored in, that is, the correction upper limit value and the correction lower limit value are compared, and if the correction current value exceeds the correction limit value, the light emitting diode (S49) corresponding to the mobile device currently selected in S49. 36 to 46)
When is turned on, it is displayed that the correction limit has been reached, and the correction limit signal is supplied to the PC 56 in S50. In PC56, the necessary processing is performed according to this correction limit signal, and the correction limit signal is also sent to ANDON, and a message to that effect is displayed. It is possible.

On the other hand, if the correction limit has not been reached, the correction limit arrival display is turned off in S51, and the correction limit signal is turned off in S52.

In this way, since the correction limit signal is created in the correction amount monitor / change device 8, it is not necessary to supply the correction limit signal from the PC 56 to the correction amount monitor / change device 8, and the number of contacts and wiring is reduced. be able to.

Next, the battery abnormality detection processing will be described with reference to FIG. If the battery abnormality detection unit 74 detects that the voltage of the battery 72 has dropped below the set value, S61
The determination result of is YES, and it is determined in S62 whether the battery abnormality confirmation flag provided in the work area of the RAM 68 is set. When S62 is executed for the first time, the determination result is NO, and in S63, the light emitting diode 50 is turned on and the battery abnormality is displayed. Subsequently, S64 is executed, and the correction amount monitor / change device 8 to PC5
The continuous operation allowance signal that had been issued up to 6 is O
FF. As a result, when the operation of one cycle of NC58 is completed, the start of the next cycle is prohibited. On the other hand, in the correction amount monitoring / changing device 8, S65 is repeatedly executed, and if the operator notices the lighting of the light emitting diode 50 or the battery abnormality display of ANDON and operates the mode selection switch 20 for a longer time than usual, S65 of The determination result is YES, the battery abnormality confirmation flag is set in S66, and then the continuous operation permission signal is set to O again in S68.
Since it is N, the NC 58 can start the next working cycle. Then, the determination result of S62, which is executed after the determination result of S61 becomes YES again, becomes S6.
Even if 3 to S67 are bypassed and the battery abnormality detection unit 74 detects the abnormality of the battery 72, the NC 58 can continuously repeat the operation cycle.

As is clear from the above description, in this embodiment, the terminal No. 4 corresponds to the output terminal described in the utility model registration claim, the correction No. selection switch 18 corresponds to the selection switch, and the No. 10 The terminals 17 and 21 correspond to the selection input terminals. In addition, the correction No. display 12 corresponds to the display of the device to be selected, and the 11th terminal for inputting the positive correction command signal, the 12th terminal for inputting the negative correction command signal and the correction reset command signal input The 13th terminal corresponds to the information input terminal, and a positive correction command for the cutting tool correction amount,
The minus correction command and the correction reset command correspond to the related information input to the information input terminal, the current value of the blade correction amount corresponds to another related information created in the monitor device, and the correction current value and the correction in the RAM 68 An area for storing the increment value corresponds to a storage section, which is a part of the computer in the correction amount monitor / change device 8 that executes the correction processing program of FIG.
Corresponding to the related information generator is one that adds the correction increment value to the correction current value of, subtracts the correction current value by the correction increment value according to the minus correction command, and resets the correction current value according to the correction reset command.
