FIG. 1 is a configuration diagram of a transport system using TRC according to the present invention;
FIG. 2 is a configuration diagram of the carrier control system, and FIG. 3 is a traveling map diagram.

First, the configuration of the TRC will be explained. As shown in FIG. 2, the TRC 12 has a control unit 12-! which manages and controls the entire TRC. , a transmitting/receiving section 12-2 that performs wireless communication with the fixed station 13, a memory 12-3, a key 12-4, a vehicle running control signal generating section 12-5, and a buzzer 12-6. The memory 12-3 includes a ROM in which wireless communication control procedures are written, a RAM in which various data are stored, and the like.

On the other hand, the transport vehicle 11 has an electric power supply that supplies power to the servo mechanism that drives the motor and the handle, starts the motor,
A switch 11-2 for stopping, a motor 11-3 for driving the transport vehicle, a control device 11-4 for controlling the servo mechanism, and an interface 11 for inputting control signals to this control device.
-5, consists of a servo mechanism 11-6 for operating the handle, a handle 11-7 for operating the transport vehicle, a manual operation key 11-8 for the switch 11-2, a sensor 11-9 for detecting obstacles, etc. .

Therefore, the TRC 12 is attached to a predetermined TRC receiver of the transport vehicle 11. When this TRC is installed in the specified position,
A terminal of the vehicle running control signal generating section 12-5 is connected to an input terminal of the transport vehicle interface 11-3.

Therefore, in order to move the conveyance vehicle 11, the destination position is selected using the key 12-4 of the TRC 12, and the start key within the key 12-4 is operated.

Now, as shown in FIG. 3, a case will be described in which the transport vehicle 11 is transported from the current position D-1 to the destination position A-4.

When the receiving unit 19 receives the start signal from the key 12-4 of the TRC 12 via the fixed station 13 and a transmission line 17 such as a LAN, the receiving unit 19 transmits the D-1/A-4 information to the destination detecting unit 21 provided in the control center 18. to notify. This destination detection section 21
Now, based on the above information, the route information (A
-1, 8-2, 8-4, D-4 are not passable)
A-3→A-4), and notifies the movement detection unit 20 and sends a motor start signal to the guided vehicle 11 via the transmission unit 23. When the TRC 12 receives this signal, the vehicle running control signal generator 12-5 and the interface 11-
5. Operate the switch 11-2 via the control device 11-4 to start the motor 11-3 of the transport vehicle 11. The movement detection unit 20 constantly grasps the position information sent from the TRC 12 of the guided vehicle 11, and when it detects that it has arrived at point C-1, it instructs the guided vehicle 11 to turn 90 degrees to the left. When the TRC 12 receives this, it operates the servo mechanism 11-6 via the vehicle running control signal generator 12-5, the interface 11-5, and the control device 11-4, controls the steering wheel 11-7 according to the instruction, and controls the steering wheel 11-7. Rotate it 90 degrees. Similarly, the direction of the transport vehicle is controlled by 90 degrees to the right at point C-3 and 90 degrees to the left at point A-3. wL transport 11
When detecting that the has arrived at point A-4, the transmitter 23
A motor stop signal is sent from the fixed station 13 to the transport vehicle 1 via
Send to 1. Upon receiving this, the vehicle driving control section signal generating section 12-5 of the TRC 12, the interface 11-5,
Switch 11-2 is operated via control device 11-4 to stop motor 11-3. At the same time as the motor of the transport vehicle 11 is stopped, the TRC buzzer 12-6 sounds.

The recipient takes out the package from the transport vehicle 11 and presses the TRC key 1.
Operate the end key from 2-4. When the receiving unit 19 of the control center 18 receives the completion of the work, the conveying vehicle 11 is controlled in the same manner starting from the position A-4 and reaching the conveying vehicle yard, contrary to the above. It goes without saying that the transport vehicle 11 can be transported with A-4 as the starting point and D-1 as the ending point.

Note that the guided vehicle 11 is equipped with a sensor 11-9 that detects obstacles, and when an obstacle is detected while the guided vehicle 11 is traveling along a set route, a switch 11-2 is activated via the control unit W11-4. is turned off, and the motor 11-3 is automatically stopped. In addition, starting the motor 11-3 from the transport vehicle 11,
If it is necessary to manually operate the stop, the operation key 11-8 can be used.

Furthermore, if it is desired to set the route of the guided vehicle in the control center 18, the setting key 22 can be used to input information.

In the movement detection unit 20, if the position information of the guided vehicle 11 does not change after a certain period of time has elapsed, it is determined that the guided vehicle 11 has stopped due to an obstacle, and the route is reset to the destination detection unit 21. When a failure is detected at C-2, the route starting from c-2 (C-2→C-1→D-1-D-2-D-
3-0-3→B-3-A-3-A-4).

The method of controlling the transport vehicle 11 after this is the same as before.

Also, it will stop in the event of a collision with a person, but this is only a temporary failure and it can quickly return to normal, so TR
Operate the fault release key among keys 12-4 of C.

If the movement detecting section 20 receives this release signal within a certain period of time while observing changes in the previous position information, it will start controlling the vehicle along the same route as before. In the case of this transportation method, the starting point and the ending point can be arbitrarily set as long as there is no problem with the location. That is, in FIG.
If it is not passable, A-1, A-4, D-4, etc. can also be used as starting points.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the Invention) As described above in detail, according to the present invention, a plurality of fixed stations are arranged in an area where a guided vehicle is to be transported, a control center connected to the fixed stations is provided, and a control center connected to the fixed station is provided.
