Automobile body tracing system for automobile production workshop

Abstract

The invention provides an automobile body tracing system for an automobile production workshop, comprising code carriers, read / write heads, display screens, a PLC, and a computer. One or more code carriers are installed on a production conveying mechanism, and one code carrier corresponds to one automobile body position on the production conveying mechanism. The first read / write head is installed on a start station corresponding to the production conveying mechanism, and the other read / write heads are installed on operation stations needing a read / write head. The start station and the operation stations are each equipped with one display screen, and the display screens correspond to the read / write heads on the stations in a one-to-one mode. The PLC is used as a controller. The computer pre-stores the information of all models. The PLC is connected with the computer. The PLC is connected with the read / write heads on the stations and the corresponding display screens. The read / write heads and the code carriers communicate based on radio frequency. According to the invention, the positions of automobile bodies can be known in real time, and part information needed for operation on the stations can be displayed.

Description

technical field [0001] The invention relates to the field of conveyor control of an automobile production line, in particular to a vehicle body traceability system in an automobile production workshop using a read-write head identification system.
