Communication method for assembly line RFID interface control unit and upper computer

Abstract

The invention discloses a communication method for a pipeline RFID interface controller and a host computer, wherein, each work station of the pipeline is provided with a RFID interface controller, and the interface controller is communicated with the host computer through a CAN bus interface. Before the pipeline runs, host computer software initializes the interface controller and sets the working state of the interface controller. When the pipeline runs, the interface controller collects material information, human-computer interaction terminal related information and equipment fault diagnosis information which are labeled with a RFID sign on the pipeline, and sends the collected information to the host computer through the CAN bus in a certain protocol format. Host computer monitoring software receives the information and processes the information, and controls an executive mechanism to act correspondingly, thus realizing optimal operation for distributing materials on the pipeline, and meanwhile, realizing the local displaying of pipeline state information on the human-computer interaction terminal. The method of the invention provides a means for the application of the RFID technology on the pipeline, for the collecting, monitoring and distributing scheduling of material and operation information, and for the efficient and information management of production.

Description

Technical field: [0001] The invention relates to the processing fields of discrete manufacturing industries such as textiles, clothing, electronics, toys, food, and automobile manufacturing, and in particular relates to a communication method for an RFID interface controller and a host computer used in a processing line. Background technique [0002] As we all know, my country is a big country in the manufacturing and processing industry, but the traditional manufacturing and processing industry has higher energy consumption and lower efficiency than developed countries. With the increasingly tense global energy and rising labor costs, the manufacturing and processing industry is facing the severe test of rising costs and declining profits. If information technology and modern management methods can be used in traditional manufacturing and processing industries, especially for discrete manufacturing industries, more intelligent material distribution and monitoring systems ca...

Problems solved by technology

At the same time, there are also many manufacturers producing RFID readers at home and abroad, but the RFID readers of these manufacturers have different interface methods. When applying, they need to build a proprietary system that matches their products, and develop special systems for their products. The host computer control software of the reader, which brings difficulties to the application of RFID technology
