Description

The present invention relates to an apparatus for managing vehicles in a storage area.

2. Description of the Related Art FIG. 8 shows a conventional vehicle management system, in which a completed car storage area is divided into a plurality of storage areas 1, 2, 3, and 4 by a vehicle type, a destination, and the like. This storage area 1
In order to temporarily store vehicles 5,6,7,8 that can be assembled and sold in ~ 4, the vehicle types and destinations of vehicles 5-8 to be temporarily stored in a plurality of storage areas 1-4 While the vehicles 5 to 8 are parked in storage areas 1 to 4 that match the ground or the like, a sheet on which identification numbers are written is attached to windshields of the vehicles 5 to 8.

Problems to be Solved by the Invention However, when carrying out a predetermined specific vehicle such as the specific vehicle 5a from among a large number of vehicles 5 to 8 parked in the storage areas 1 to 4, the worker attaches the specific vehicle 5 to the windshield. Since the specific vehicle 5a is carried out while checking the parking position of the specific vehicle 5a by searching for the identification number of the paper that has been set, the number of vehicles located in the storage area 1 where the specific vehicle 5a is parked is A great deal of labor and time is required to find one specific vehicle 5a to be carried out from among the five vehicles. In addition, the production ratio of the vehicle type and the destination in vehicle manufacturing fluctuates, and the number of parked vehicles in the storage areas 1 to 4 increases and decreases.
If 4 is partitioned by vehicle type, destination, etc., it is difficult to effectively use storage areas 1 to 4.

Means for Solving the Problems Therefore, in the vehicle management device of the present invention, a plurality of rotary antennas for searching a storage area where a large number of vehicles are parked, and a plurality of vehicles that are parked in the storage area Input means for inputting identification information unique to the vehicle in order to search for a specific vehicle from among them, and a position detecting means together with the antenna and the input means, and the identification information input by the input means is used to identify the antenna. A controller having a function of transmitting and a function of receiving, and separately mounted on a large number of vehicles parked in the storage area, having a transmitting / receiving function and a matching processing function, transmitted from the antenna. When the identification information is received, the identification information is compared with the pre-stored unique self-identification information, and when both match, a registration signal is transmitted. Identification means, and antenna rotation angle detection means for detecting the rotation angle of each of the antennas and outputting the detected rotation angle to a controller. The parking position of the specific vehicle in the storage area is specified and instructed based on the signal reception level and the rotation angle position of each antenna.

Effect The vehicle is parked in the storage area while the identification means can be received. Then, when carrying out the specific vehicle, the operator operates the input means of the position detecting means and transmits an identification signal corresponding to the specific vehicle to be carried out from the position detecting means. Then, the identification means of each vehicle receives the transmitted identification signal, determines whether or not the received identification signal matches the self-identification information stored in its own identification means, An enrollment signal is transmitted when the signal matches the self-identification information. When the position detection means receives the enrollment signal, the position detection means determines the origin of the received enrollment signal, thereby detecting the parking position of the specific vehicle to be carried out and instructing the detected parking position. In accordance with the instruction of the parking position, the worker goes to the specific vehicle parked in the storage area and carries out the specific vehicle from the storage area.
