Description

[Detailed Description of the Invention] A. Industrial Application Field The present invention relates to an operation control device for an unmanned vehicle.

B. Outline of the Invention In the present invention, the operation control device of the unmanned vehicle is provided with a determination unit for determining whether there is a transfer start command or a transfer end command, and the unmanned vehicle is located in the transfer area between each command. The wireless control is enabled by controlling the running and stopping depending on the presence or absence of the wireless signal at this time, and the operation at the time of transfer is simplified.

C. Conventional technology An unmanned vehicle travels along a road such as a guide line to load or unload luggage in any transfer area.

D. Problems to be solved by the invention In an unmanned vehicle that does not have an automatic transfer device, if the unmanned vehicle arrives at the transfer place, the worker is unattended The driver operates the temporary stop switch to stop the unmanned vehicle, and after the transfer is finished, operates the switch again to release the temporary stop and drive the vehicle. Since this operation is repeated for each transfer location, the operation becomes troublesome when there are many transfer locations. In addition, as another method, mark plates should be installed at all places where transfer is supposed to take place, and the vehicle should be stopped regardless of whether or not transfer is performed. The worker operates the switch on the operation part of the vehicle to start the vehicle. Therefore, in this method, the vehicle is often started and stopped, and the operation of the worker is often troublesome.

The present invention has been made in view of the above points, and an object of the present invention is to provide an operation control device that is easy to operate.

E. Means for Solving Problems The present invention installs mark plates at the start point and the end point of the transfer area in the operation control device of the unmanned vehicle. Also,
The unmanned vehicle has a receiving unit that receives a wireless signal, a determination unit that determines the transfer area start point and the transfer area end point, and a control unit that determines the presence or absence of a wireless signal to stop or start the vehicle. It is provided.

F. Action The stop and start operations of the unmanned vehicle in the transfer area are performed by the signal from the wireless device carried by the worker. The unmanned vehicle determines whether or not there is a radio signal on condition that the transfer start point has been passed and the transfer end point has not been passed, and the driverless vehicle automatically stops or starts.

G. Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a course diagram in which a guide wire is laid as a traveling path 1. An unmanned vehicle 2 towed by a towing vehicle 2 a travels along the traveling path 1. 3 is a transfer start mark plate, 4 is a transfer end mark plate, and each mark plate
The length 1 between 3 and 4 will be the area for transferring packages. Therefore, the transfer area 1 has a plurality of parts shelves 5a to 5n, and the unmanned vehicle 2 stops at any installation of the parts shelves.

FIG. 2 shows a control device, 10 is a control device mounted on an unmanned vehicle, and 20 is a wireless device carried by an operator. The control device 10 includes a receiving unit 11 for receiving a radio signal, a detector 12 for detecting the mark plates 3 and 4, and a judging unit for judging the presence or absence of a command for detecting the transfer start and end mark plates. 13 and a control unit 14 that determines the presence or absence of a radio signal based on this determination and stops or starts the unmanned vehicle based on the result. The operation of the present invention constructed as above will be described with reference to FIG. When the unmanned vehicle 2 traveling in the direction of the arrow on the traveling path 1 enters the transfer area and, for example, is stopped and transferred to the parts shelf 5b, when the unmanned vehicle 2 reaches the position of the shelf 5b. The switch SW of the wireless device 20 is turned on to detect a signal.

On the other hand, on the unmanned vehicle 2 side, the determination unit 13 determines whether or not there is a detection command of the transfer start mark plate 3 detected by the detector 12 as shown in step S ₁ in FIG. Make a decision. If there is no command, the car will continue to run, but here the unmanned vehicle 2 is already on the mark plate 3
Since it has passed the position of, the command is present. If yes, go to step S ₂ to see if there is a transfer end command
Is judged. Unmanned vehicles are still mark plate 4
Since it has not passed
Move to S ₃ . In step S ₃ , the control unit 14 determines whether or not there is a wireless input, and if there is, a predetermined control for stopping the unmanned vehicle is performed. Transfer is completed, and radio 20
When the switch SW is open state, the step S ₃ in free determination is made, control for unmanned vehicle running is performed.
Note that stop-free time in step S _3, it may be performed to control the travel when closed is a matter of course.

H. Effect of the Invention According to the present invention, when the unmanned vehicle arrives at the transfer location,
Since it is only necessary to turn on or off the switch of the radio, you do not have to go to the operation part of the car each time and stop or operate for traveling, so the work can be simplified and speedy It becomes possible to perform work.
Also, the mark plate installed on the ground only needs to have the start point and the end point of the transfer area, and the number thereof is very small.
