The paging subsystem goes from the paging device to the vehicle driver via the antenna and provides various information such as light information, waiting time, and emergency contact. It is handed over to the driver and collected when exiting the gate. The data processing subsystem registers the receiving/shipping schedule file such as the day's trading company and receiving/shipping pass number, reads RF-ID data in real time, displays the paging device and display light on the display board, and records the work time, waiting time, etc. It collects various data, outputs messages to the paging device, etc.

Next, the hardware configuration of the vehicle guidance system will be explained with reference to FIG.

In FIG. 5, an antenna 11 and a transmitter/receiver 12 are used to read RFiD data of an introductory vehicle, and a display board 1
3 displays the destination for the Dalian vehicle.

The entry processing terminal 14 is equipped with a barcode reader and a keyboard, issues an RF-ID transmitter to a vehicle that does not have an RF-ID transmitter, and registers the vehicle for entry. An antenna 15 and a transmitter/receiver 16 are installed in each perspective, and the RF-■D of the vehicle receiving and shipping work is installed.
It reads data, and includes a display board 17 and an antenna 1.
8 and a transceiver 19 are installed in the waiting area, and a display board 20, an antenna 21, and a transceiver 22 are installed at the exit, and are used to read RF-10 data and display the destination, respectively. Antenna 23 and transmitter 24 are for transmitting information to paging device 25. The management workstation 26 manages this input/output information.
It has a printer 27 and a barcode reader 28.

With the hardware configured above, when a vehicle enters the vehicle, the RF-I of the vehicle is transmitted through the antenna 11 and the transceiver 12.
Read the D data and perform introductory registration. With this introductory registration, the management workstation 26 responds to the vehicle and displays the destination on the display board 13. In this case, if the large shipment bus for that vehicle is not available, the waiting area is designated as the destination. In the waiting area, a vehicle is recognized through an antenna 18 and a transmitter/receiver 19, and when a large shipping parcel becomes available for that vehicle, the receiving/shipping parcel is indicated on the display board 17 as the destination. Then, when the work on the large shipment purse is completed and, for example, a work end switch (not shown) is operated, the management workstation 26 recognizes this and instructs the next destination using the paging device 25. The δ blood returned from the exiting vehicle is sent to the RF-ID through the antenna 21 and transceiver 22.
This is done by reading data, and the display board 20 displays a message indicating that it is OK to exit the gate. In other words, from introductory registration to exit O
Until K, management is performed by the management workstation 26 reading RF-ID data for each vehicle and issuing optical instructions.

However, the present invention is not limited to the above-described embodiments, and various modifications are possible. For example, in the above embodiment, text broadcasting is performed on the display board, but it goes without saying that the system may be configured to provide desired information using a display or the like. In addition, RF-ID data reading may be performed using a system that consists of a transponder and a sensor accessor, and uses extremely low electromagnetic waves emitted from the sensor detection section to resonate with the transponder to identify the code. The vehicle identification code may be recorded on a barcode card, an IC memory card, or other recording card, and the vehicle identification code may be read using these reading devices instead of the antenna and receiver.

In addition, antennas and text broadcasting devices that identify RF-ID multipliers will be installed on the main roads around the facility, and information on the facility and other information will be communicated in advance to help with time adjustment and other stopovers. It is possible to control the flow of vehicles, such as taking detours.

〔Effect of the invention〕
