Abstract

The invention provides a workshop production monitoring system and method. A monitoring system PLC is used as a core, unified ultrahigh-frequency RFID is adopted for key points of all line bodies in awhole workshop, on-line monitoring of a whole-workshop vehicle queue is automatically achieved, on the basis of the queue, based on a stable and reliable PROFINET communication protocol, automatic program recognition of workshop equipment is achieved, a redundant scheme is adopted, assembly mistake-proofing interlocking of single-machine equipment and a conveying line is achieved, and it is guaranteed that no defective products flow out; through an optical fiber ring network, assembly process data and equipment state information are collected in real time and process analysis is performed soas to effectively guide production and manage equipment; and finally, automation and informatization of production in a final assembly workshop are achieved, and the efficiency of final assembly production and the assembly quality are improved.

Description

technical field [0001] The present invention relates to the field of workshop production monitoring, more specifically, to a workshop production monitoring system and method. Background technique [0002] Most of the existing automobile workshop production monitoring systems use a large number of high-frequency RFIDs to realize the online queue generation and monitoring of the workshop, and communicate with each stand-alone device through the TCP / IP communication protocol to realize the production control of the stand-alone device. In particular, there are a large number of electric tightening equipment in the assembly workshop. The system judges the result by collecting its data, and finally outputs it to the conveyor line to realize interlocking. [0003] Different lines of the assembly workshop adopt different forms of RFID. The read-write head of the controller is fixed on the ground of the interior line, the steel structure of the chassis line, and the ground of the ext...
