RFID interface controller of discrete manufacturing business machining assembly line

Abstract

The invention relates to an RFID interface controller used in a machining flow line of the discrete manufacturing industry. The RFID interface controller has a hardware middleware function between upper computer software and an RFID reader-writer. The RFID interface controller is characterized by comprising an RFID reader-writer interface for power supply and communication from the controller to the external reader-writer; a human-machine interaction terminal interface for the power supply and the communication from the controller to the an external terminal; a field bus interface for the communication between the controller and the upper computer; an extended memory for power-down storage of controller setup parameters; a processor capable of realizing the functions of driving various communication interfaces, protocol encapsulation, analysis and conversion, as well as task scheduling and coordination; and a power supply and a protection circuit which are used for providing reliable power supply for the processor, the communication interfaces and peripheral equipment. The invention relates to application of the RFID technology to the machining flow line for real-time monitoring and allocation scheduling of material data and operation information, and provides a means for realizing high-efficiency production and informatized management.

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, in particular to an RFID interface controller for a processing line of discrete manufacturing industries. 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 sources and rising labor costs, the manufacturing and processing industry is facing the severe test of rising costs and falling 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 can be used to improv...

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
