Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a mobile body that transmits multiple types of work information from a command center such as an office to a work vehicle such as a forklift that is working inside a factory, warehouse, etc. The present invention relates to communication devices.

[Prior Art] Conventionally, this type of mobile communication device receives work information transmitted from a transmitter in an office, for example, with a receiver mounted on a forklift, and displays the work information on a display device. In addition, there is a mobile communication device that uses a buzzer to emit a notification sound (see Japanese Patent Laid-Open No. 193342/1983). According to this mobile communication device, a worker can be notified by a display device that work information has been received. You can hear the notification sound from the buzzer without having to look at it.

[Problem to be Solved by the Invention] However, in the conventional mobile communication device, the notification sound by the buzzer is always constant regardless of the content of the work information transmitted from the office, so it is not possible to receive an emergency instruction. There was a problem in that it was not possible to judge whether or not the notification sound was made only by the notification sound.

The present invention was made in view of the above-mentioned circumstances, and
The purpose of this is to be able to determine whether or not the work information is urgent without looking at the display when work information is received from the command center, and to take immediate action even if urgent work information is received. An object of the present invention is to provide a mobile communication device that can improve work efficiency.

[Means for Solving the Problems] Therefore, in order to achieve the above object, the present invention provides a transmitting means that is provided in a command center and transmits a plurality of pieces of work information and emergency information indicating whether or not the same work information is urgent. , a receiving means provided on a working vehicle that performs work in the premises and receiving the current work information from the transmitting means; provided on the working vehicle;
a display means for displaying the work information received by the receiving means; a notification means provided on the work vehicle to notify the worker by sound or light that the work information has been received by the receiving means; The gist of the present invention is to provide a mobile communication device including a control means for controlling the sound, light, etc. emitted from a notification means to vary depending on whether work information based on emergency information is urgent or not.

[Operation] When a plurality of pieces of work information and emergency information indicating whether or not the same work information is urgent are transmitted from the transmission means of the command center, those work information and emergency information are received by the reception means of the work vehicle, and the same work Information is displayed on the display means, and sound, light, etc. are emitted from the notification means. At this time, the sound or light emitted from the notification means is controlled differently based on whether the work information is urgent or not.

[Example] An example embodying the present invention will be described below with reference to the drawings.

As shown in Figure 1.2, a transmitting/receiving device 4 is installed in an office 1 serving as a command center as a transmitting means for transmitting messages to a forklift 3 serving as a work vehicle working within the premises of a factory 2. has been done.

This transmitting/receiving device 4 includes an input section 6 such as a keyboard for inputting messages, a control section 7 that controls input signals from the doujinshi blade section 6 and inputs/outputs electrical signals, and It is comprised of a radio section 8 that transmits electrical signals as radio waves and receives radio waves from the forklift 3.

The radio section 8 is equipped with an FSK modulation circuit and a demodulation circuit, and is configured to use the frequency of an empty television channel and to transmit and receive weak radio waves that are not subject to the regulations of the Radio Law.

The message inputted by the input unit 6 includes a plurality of pieces of work information for instructing the worker W of the forklift 3 about the contents of the work, and emergency information indicating whether or not the work information is urgent. For example, a code number is used as this emergency information, and in this embodiment, the code number "00" is usually used for work information that does not need to be done quickly, and the code number "00" is used for work information that needs to be done quickly. Emergency code number "ol"
” is entered along with the work information.

As shown in FIG. 2.3, a transmitting/receiving device 5 serving as a receiving means for exchanging radio waves with the transmitting/receiving device 4 is mounted on the instrument panel ll of the forklift 3. The transmitting/receiving device 5 is equipped with an FSX modulation circuit and a demodulating circuit similar to the radio unit 8, and uses the frequency of an empty TV channel and is a wireless device for transmitting and receiving weak radio waves that are not subject to the regulations of the Radio Law. A control section 10 is connected to the radio section 9.

On the output side of the control unit 10, there is a liquid crystal display (hereinafter referred to as LCD) 12 as a display means for displaying the current work information received by the wireless unit 9, and the work information displayed on the LCD 12. A printer 13 for appropriately printing on printing paper P is connected. These LCD 12 and printer 13 are incorporated into the front panel 5a of the transmitting/receiving device 5.

Also, connected to the output side of the control section 10 is a revolving light 15 that turns on when work information is received by the wireless section 9 . This revolving light 15 is provided on the helad guard 14 of the forklift 3 (see FIG. 1), and even when the worker W is away from the forklift 3, the work information can be received by the wireless section 9. It is designed to notify you.

Furthermore, on the output side of the control unit 10, a first buzzer 16 that emits a notification sound when the normal code number "00" is received by the radio unit 9 as the emergency information, and a first buzzer 16 that emits a notification sound when the normal code number "00" is received as the emergency information, and
A second buzzer 17 is connected, which emits a notification sound different from the notification sound of the first buzzer 16 when the radio unit 9 receives "01". Both the buzzers 16 and 17 are arranged in parallel on the upper part of the front panel 5a of the transmitting/receiving device 5, and in this embodiment, the first buzzer 16 produces a "holo horo" sound, and the second buzzer
Each of the buzzers 17 emits a "bee beep" sound, and the two buzzers 1617 constitute a notification means.

On the input side of the control unit 10, there are buttons 6111-2 that are pressed by the worker W to stop the buzzers 16 and 17 after confirming their operation, and a button 18 that is pressed to stop the buzzers 16 and 17, and a button 18 that allows the worker W to perform work based on the instructed work information. After completion, the LCD 12
and a completion button 19 that is pressed to erase the display contents displayed on the screen. Both buttons 18, 19 are integrated into the front panel 5a of the transceiver device 5.

When the work information is received by the wireless unit 9, the control unit 10 determines whether or not the work information is urgent based on the code number of the emergency information received together with the work information, that is, the normal code number “00” is received. or whether emergency code number "01" was received. If it is determined that the received code number is the normal code number ro OJ, the control unit 10 then determines whether the forklift 3 is in a standby state (described later), and if it is in a standby state, the LCD 12 displays In addition to displaying work information, the first buzzer 16 is activated to generate a "holo horo" sound.

On the other hand, if it is determined that the code number received by the radio section 9 is the emergency code number "01", the control section 10
displays the received work information regardless of the display on the LCD 12.
This is displayed on the CD 12 for a certain period of time, and a second buzzer 17 is activated to generate a "beep" sound.

When another piece of work information is received by the wireless unit 9 while the work information is being displayed on the LCD 12, the control unit 10 temporarily stores that piece of work information in the internal memory, and also displays the number of received pieces of work information. is displayed on the LCD 12. The display rl/4J on the upper part of the LCDI 2 in FIG. 3 indicates that the number of received work information is four, and the first received work information among them is displayed on the LCD 12.

The display contents of the LCD 12 can be sequentially switched by pressing a switch button 20 built into the upper part of the front panel 5a. At this time, the display of rl/4J changes to r2/4J, r3/4J, etc.

When the work is performed according to the work information displayed on the LCD 12 and the completion button 19 is pressed, the control unit 10 erases the displayed content and displays the next work information stored in the internal memory on the LCD 12. It is designed to let you do so. At this time, the number of received and unprocessed work information decreases by one, so the display of rl/4 J at the top of the LCD 12 changes to rl/3 J. And as mentioned above, 1
When the work progresses one by one and the unprocessed work information becomes 0, nothing is displayed on the LCD 12. The state at this time is a standby state for waiting for the next work information to be transmitted. Of course, even if no work information is received and no display is made on the LCD 12 since the start of operation of the forklift 3, the forklift 3 is also placed in a standby state.

By the way, when the confirmation button 18 is pressed, the control section 10 causes the radio section 9 to transmit confirmation information to notify the office 1 that the operation of the buzzers 16 and 17 has been confirmed. Further, when the completion button 19 is pressed, the control section 10 causes the wireless section 9 to transmit completion information to inform the office 1 that the work based on the instructed work information has been completed.

A numeric keypad 21 is incorporated on the front panel 5a of the transmitting/receiving device 5, and by operating the numeric keypad 21, it is possible to input information to be transmitted to the office 1 manually.

Next, the operation of the communication device of this embodiment configured as described above will be explained based on the flowchart shown in FIG.

First, the control unit 10 of the transmitting/receiving device 5 in the forklift 3 waits for the radio wave from the transmitting/receiving device 4 in the office 1 to be received by the wireless unit 9 (step 1, hereinafter, step is denoted by S), and then the control unit 10 waits for the radio wave from the transmitting/receiving device 4 in the office 1 to be received by the wireless unit 9 (step 1, hereinafter, step is denoted by S). When it is determined that the work information has been received, it is then determined whether the work information is urgent (S
2). This determination is made based on the code number sent together with the work information. That is, the control unit 10 determines whether this code number is the normal code number "00" or the emergency code number "01."

When determining that the code number is the normal code number "00", the control unit 10 determines that the received work information is not urgent, and then determines whether the forklift 3 is in a standby state, that is, It is determined whether display is being performed on the LCD 12 (S3). If the control unit 10 determines that the forklift 3 is in the standby state, it determines that the forklift 3 has not received any work instructions since the start of operation, or that the work has been performed according to the received work information and is waiting for the next work information. Then, the received work information is displayed on the LCD 12 (S4), and the first buzzer 16 is activated.
A holo holo sound is generated (S5).

Therefore, without looking at the LCD 12, the worker W can know from the "holo horo" sound that non-urgent work information has been received.

Note that when the control unit 10 determines in S3 that the forklift 3 is not in the standby state, the previously received work information is
Based on the work information displayed on the CD 12, it is determined that the work is being performed, and the work information received on the Sl is not displayed on the LCD 12, and both buzzers 16 and 17 are not activated.

At this time, the control unit 10 stores new work information in the internal memory and changes the display of rl/4J on the upper part of the LCD 12 to r115.
Let J change it. Then, the control unit 10 returns to the Sl, and the previously received work information is advanced one by one,
Wait until all the work information before S1 is completed and enter the standby state.

On the other hand, if it is determined in S2 that the emergency code number "01" has been received, the control unit 10 unconditionally displays the received work information on the LCD 12 regardless of whether or not the forklift 3 is in a standby state (S6). Activate the second buzzer 17 to generate a "beep" sound (
S7). Therefore, without looking at the LCD 12, the worker W can know that urgent work information has been received by hearing the "beep" sound.

The control unit 10 causes the LCD 12 to display urgent work information and at the same time starts measurement by a timer, and when a predetermined time has elapsed, erases the display and causes the LCD 12 to display the work information immediately before the same display. .

After the worker W confirms that the first buzzer 16 or the second buzzer 17 has been activated as described above, the control unit 10 waits for the confirmation button 18 to be pressed (S8), and when the confirmation button 18 is pressed. If it is determined that the button has been pressed, the operation of the buzzers 16 and 17 is stopped (S9), and confirmation information is transmitted from the wireless section 9 to notify the office 1 that reception of the work information has been confirmed.

Subsequently, the control unit 10 causes the operator W to press the completion button 19.
It waits for the button 19 to be pressed (S10), and when it determines that the completion button 19 has been pressed, it erases the work information displayed on the LCD 12 (Sll) and notifies the office 1 that the work has been completed. The wireless unit 9 transmits the completion information. Then, the control unit 10 returns to Sl and waits for new work information to be received.

In addition, when the second buzzer 17 notifies the worker W that the urgent work information has been received in S7, the worker W receives the work information that was displayed immediately before the urgent work information. Completed work based on LC at 311
By pressing the switching button 20 after erasing the display of D12, emergency work information can be displayed on the LCD 12.

As described above, according to the communication device of this embodiment, when the worker W of the forklift 3 receives work information from the office 1, he can check whether the transmitted content is urgent without looking at the LCD 12. can be judged. Therefore, unlike the conventional one, when the forklift 3 is operating, the buzzer 16
．． To check the urgency of the work information every time the 17 rings,
There is no need to move the line of sight to look at the LCD 12, and work efficiency is improved accordingly. Furthermore, since the notification sound from the second buzzer 17 allows the operator to know that emergency work information has been received, it becomes possible to immediately respond to emergency instructions and the like.

It should be noted that the present invention is not limited to the configuration of the embodiments described above, and may be modified as desired without departing from the spirit of the invention, for example, as described below.

(1) In the embodiment described above, two buzzers 16 and 17 were installed, but three or more buzzers may be installed so that each buzzer generates a different notification sound. For example, if the number of buzzers is 4, an emergency delivery instruction will be sounded with a "boo boo j" sound, an urgent stock entry instruction will be made with a "holo horo" sound, and an urgent additional order will be made with a "boo holo" sound.
An emergency cancellation instruction can be distinguished by a beeping sound and a beeping sound.

(2) A single buzzer may emit a plurality of different types of notification sounds. For example, the tone color of the buzzer can be changed by changing the energization time of the same sound or by changing the energization timing. It is also possible to change the timbre by changing the pitch or volume.

(3) A lamp may be used as the notification means instead of the buzzers 16 and 17 in the above embodiment. In this case, it is possible to change the color of the light emitted by the lamp or change the lighting method such as lighting timing.

(4) In the above embodiment, the transmitting means and the receiving means are wireless, but wired or infrared rays may also be used.

(5) The present invention can be applied to construction machinery other than forklifts.

[Effects of the Invention] As detailed above, according to the present invention, when work information is received from a command center, it is possible to judge whether or not the work information is urgent without looking at the display means. When work information is received, immediate action can be taken.
This has the excellent effect of making it possible to improve work efficiency.
