The figure which shows a mode that the display apparatus 120 of the communication apparatus 100 of the aerial work vehicle of FIG. 2 was installed in the cabin 11 of the aerial work vehicle 10 of FIG.

  An aerial work vehicle communication device 100 according to an embodiment of the present invention will be described with reference to FIGS. An aerial work vehicle communication device 100 according to an embodiment of the present invention is mounted on an aerial work vehicle (vehicle) 10 capable of traveling. The vehicle 10 is a highly rigid vehicle body frame including a cabin (passenger compartment) 11 in which a driver's seat is provided, traveling wheels T, a main frame MF, and a sub frame SF integrally provided on the main frame MF. F, an elevating device 12 provided on the subframe SF, a work table 13 attached to the elevating device 12 and elevating and lowering, and provided on the front left and right and rear left and right of the body frame F, and extend when working at a high place. And a jack portion 14 that supports the vehicle 10.

  The lifting / lowering device 12 includes a lift link mechanism 12a provided on the subframe SF, and a lift cylinder 12b that expands and contracts by hydraulic pressure and extends (deploys) and stores the lift link mechanism 12a. The work table 13 includes a work floor 13a and a fence (handrail) portion 13b provided around the work floor 13a. The jack portion 14 includes a jack 14a that expands and contracts by hydraulic pressure, and a rotatable roller 14b that is provided at the lower end of the jack 14a and is in contact with the ground when working at a high place.

  The communication device 100 for an aerial work vehicle according to the present embodiment includes an instruction device 110 for instructing a driver in the cabin 11 to move forward, backward, or stop the vehicle 10 from an operator on the work table 13, and an instruction device. The display device 120 for displaying the instruction content of 110 to the driver, the instruction device 110 and the display device 120 are electrically connected, and the cable 130 is connected to the power source P of the vehicle 10.

  The indicating device 110 is detachably installed by a magnet (not shown) on a fence (handrail) portion 13b in the vicinity of the work table operation device O of the work table 13. Therefore, it can move freely on the work table 13 (see FIG. 4). The instruction device 110 includes a forward signal switch 111 for issuing a forward instruction for the vehicle 10 to the driver, a stop signal switch 112 for issuing a stop instruction, a reverse signal switch 113 for issuing a reverse instruction, and an optional And a buzzer switch 114 for issuing the instruction. Each switch is an illuminated switch, and the operation part of the switch is always lit. In addition, since a different color is assigned to each switch, it is possible for an operator to reliably perform an operation without making a mistake even at night or in a tunnel.

  The instruction device 110 generates a forward instruction signal when the operator presses the forward signal switch 111, generates a stop instruction signal when the operator presses the stop signal switch 112, and generates a reverse instruction signal when the reverse signal switch 113 is pressed. When the buzzer switch 114 is pressed, a buzzer sound reproduction signal is generated. Of these switches, the forward signal switch 111, the reverse signal switch 113, and the buzzer switch 114 are ON (signal generation) only while the operator is pressing with a finger, and are OFF (signal generation is not performed) when the finger is released. End). On the other hand, once the stop signal switch 112 is turned on when the operator pushes it with a finger, the ON state is maintained even if the finger is released (the signal is continuously generated). When pressed, it is turned off (ends signal generation). As a result, even if the operator loses his / her balance and the finger is released from the stop signal switch 112 unintentionally, the stop signal switch 112 is kept in the ON state, and the stop instruction signal can be continuously generated.

  The display device 120 is installed on the dashboard D in the cabin 11. The display device 120 includes a forward indicator lamp 121, a standby indicator lamp 122, a stop indicator lamp 123, a reverse indicator lamp 124, and an audio reproduction device 125.

  The forward indicator lamp 121 is turned on when the forward instruction signal generated by the instruction device 110 is received. The reverse indicator lamp 124 is turned on when the reverse indicator signal generated by the indicator device 110 is received. The stop indicator lamp 123 is turned on when a stop instruction signal generated by the instruction device 110 is received. The standby indicator lamp 122 is lit when any signal of the forward instruction signal, the reverse instruction signal, the stop instruction signal, or the buzzer sound reproduction signal is not received with the main power source P of the vehicle 10 turned on. Each indicator light is assigned a different color.

  As described above, the forward indicator lamp 121, the reverse indicator lamp 124, or the stop indicator lamp 123 is turned on depending on the type of the received signal. Therefore, the driver in the cabin 11 is instructed by the operator. Can be visually recognized. Further, when no signal is received, the standby indicator lamp 122 is turned on, so that it is possible to visually recognize that no instruction is issued from the operator. Furthermore, since different colors are assigned to the respective indicator lights, the driver can surely recognize which indicator lights are lit.

  The sound reproducing device 125 reproduces the corresponding sound source when receiving any one of the forward instruction signal, the reverse instruction signal, the stop instruction signal, and the buzzer sound reproduction signal. The audio reproduction device 125 includes an input unit 125a that receives signals (forward instruction signal, reverse instruction signal, stop instruction signal, or buzzer sound reproduction signal), a memory 125c that stores audio data, and a signal that is received by the input unit 125a. Accordingly, the CPU 125b that reads out the corresponding audio data from the memory 125c, the conversion unit 125d that converts the read audio data into an audio signal, and the speaker 125e that converts the audio signal into audio and outputs it.

  The memory 125c stores first audio data read when a forward instruction signal is received, second audio data read when a reverse instruction signal is received, and first audio data read when a stop instruction signal is received. 3 audio data and fourth audio data read when a buzzer sound reproduction signal is received are stored. When the first sound data is read and output from the speaker 125e, the sound becomes “forward, forward”. When the second sound data is read out and output from the speaker 125e, the sound becomes “backward, reverse”. When the third sound data is read and output from the speaker 125e, the sound becomes “stop, stop”. When the fourth audio data is read out and output from the speaker 125e, the fourth audio data becomes a voice “boo”.

  As a result, when the display device 120 receives the forward instruction signal, the forward indicator lamp 121 is turned on, and in conjunction with this, the first audio data is read out and the voice “forward, forward” is output from the speaker 125e. Be emitted. In addition, when the display device 120 receives the reverse instruction signal, the reverse indicator lamp 124 is turned on, and in conjunction with this, the second audio data is read and a sound of “reverse, reverse” is emitted from the speaker 125e. It is done. Further, when the display device 120 receives the stop instruction signal, the stop indicator lamp 123 is turned on, and in conjunction with this, the third sound data is read and a sound of “stop, stop” is emitted from the speaker 125e. It is done. On the other hand, when the display device 120 receives the buzzer sound reproduction signal, each indicator lamp (forward indicator lamp 121, stop indicator lamp 123, or reverse indicator lamp 124) is not lit, but the fourth audio data is read out. Then, a buzzer sound “boo” is emitted from the speaker 125e.

  As described above, the corresponding sound is emitted from the sound reproduction device 125 in conjunction with the lighting of each indicator light, so that the driver in the cabin 11 can hear what instruction the worker is giving. It can also be recognized by information.

  Further, when a buzzer sound reproduction signal is received, a buzzer sound is emitted from the sound reproduction device 125, so that the driver and the worker make a buzzer sound in advance (or the number of times the buzzer sound is generated) and the corresponding meaning ( For example, it is possible to give any instruction other than forward, stop, reverse to the driver from the operator by deciding a 5-minute break with 3 buzzer sounds. The instruction can be recognized from the buzzer sound.

Next, a method for using the contact device 100 for an aerial work vehicle according to the present embodiment will be described along with working examples.
First, the driver in the cabin 11 moves the vehicle 10 to the work place. Next, the jack 14a is extended, and the lower end roller 14b is grounded to support the vehicle 10. Thereafter, the worker gets on the work table 13. And the raising / lowering apparatus 12 is expand | deployed and the work table 13 is moved to the height suitable for work. Here, the worker performs work. At this time, the worker moves the pointing device 110 from the vicinity of the work table operating device O to the vicinity of the work position.

  Thereafter, the operator presses the forward signal switch 111 of the instruction device 110 to instruct the driver to move to the next work place. Then, the standby indicator lamp 122 of the display device 120 installed on the dashboard D of the cabin 11 is turned off, the forward indicator lamp 121 is turned on, and in conjunction with this, “forward, forward” is displayed from the speaker 125e. A voice is emitted. Here, the driver determines that the operator on the work table 13 has issued a forward instruction for the vehicle 10 based on the lighting of the forward indicator lamp 121 and the sound emitted from the speaker 125e, and advances the vehicle 10 by depressing the accelerator. .

  The worker on the workbench 13 releases his / her finger from the forward signal switch 111 and gives the stop signal switch 112 of the instruction device 110 to issue a stop instruction of the vehicle 10 to the driver when the next work place is approaching. Push. Then, when the finger is removed from the forward signal switch 111, the forward indicator lamp 121 of the display device 120 is turned off, the standby indicator lamp 122 is turned on, and the sound from the speaker 125e is also stopped. When the stop signal switch 112 is pressed, the standby indicator lamp 122 is turned off and the stop indicator lamp 123 is lit, and in conjunction with this, a sound “stop, stop” is emitted from the speaker 125e. Here, the driver determines that the operator on the work table 13 has issued an instruction to stop the vehicle 10 based on the lighting of the stop indicator lamp 123 and the sound emitted from the speaker 125e. to go into.

  When the vehicle 10 stops, the worker presses the stop signal switch 112 of the instruction device 110 again to release the stop instruction to the driver. Then, the stop indicator lamp 123 is turned off and the sound from the speaker 125e is also stopped. Then, the standby indicator lamp 122 is turned on. As a result, the driver determines that the stop instruction from the operator has been released. Here, the worker performs work.

  When the position where the vehicle 10 is stopped has passed the work position, the worker presses the reverse signal switch 113 in order to give a reverse instruction to the driver. Then, the standby indicator lamp 122 of the display device 120 is turned off and the reverse indicator lamp 124 is turned on, and in conjunction with this, a sound “backward, reverse” is emitted from the speaker 125e. Here, the driver determines that the operator on the work table 13 has issued a reverse instruction of the vehicle 10 based on the lighting of the reverse indicator lamp 124 and the sound emitted from the speaker 125e, and moves the vehicle 10 backward.

  In addition, if the operator and the driver have previously decided to take a break for a predetermined time when the buzzer sounds three times continuously, the worker presses the buzzer switch 114 of the pointing device 110 three times in succession. When pressed, a buzzer sound “boo, boo, boo” is emitted from the speaker 125e. As a result, the driver recognizes that the operator has given an instruction to take a break for a predetermined time, and enters the break.

  When all the work is finished, the work end signal is sent from the worker to the driver. If the operator and the driver have previously negotiated the work end signal when the buzzer sound is sounded five times in succession, the operator presses the buzzer switch 114 of the pointing device 110 continuously five times. A buzzer sound “boo, boo, boo, boo, boo” is emitted from the speaker 125e. As a result, the driver recognizes that all work has been completed. Then, the elevating device 12 is stored, the work table 13 is lowered, and the worker gets off the work table 13. Thereafter, the jack 14a is stored.

  As described above, in the communication device 100 for an aerial work vehicle according to the present embodiment, the instruction device 110 receives a forward instruction signal in accordance with a vehicle forward instruction, a reverse instruction, or a stop instruction by an operator on the work table 13. A reverse instruction signal or a stop instruction signal is generated and transmitted to the display device 120. When the forward instruction signal is received, the forward indicator lamp 121 is lit, when the reverse instruction signal is received, the reverse indicator lamp 124 is lit, and when the stop instruction signal is received, the stop indicator is displayed. The lamp 123 is turned on. Thus, since the corresponding indicator light of the display device 120 in the cabin 11 is turned on according to the instruction content of the operator, the instruction content can be visually transmitted to the driver, The operator can reliably instruct the operation details to the driver in the cabin 11 without misunderstanding.

  Further, in the communication device 100 for an aerial work vehicle according to the present embodiment, a sound corresponding to the content of the operator's instruction is emitted from the speaker 125e in conjunction with the lighting of each indicator lamp. Thereby, the instruction content can be transmitted to the driver not only by visual information but also by auditory information, and the operator on the work table 13 can more reliably instruct the driver about the operation content to the driver in the cabin 11.
