Research on Design of Temperature Control System based on PLC

摘要

In many fields of scientific research and production practice, the temperature control occupies a very important position, especially with a pivotal role in the industrial and agricultural production. With the development of electronic and computer technology, PLC from the original amount of simple logic control, and gradually have the function of a computer control system, since the computing power, anti-jamming capability, response speed, communications networking capability, flexibility, and maintainability many advantages aspects, PLC has been extensive use of temperature control system, the author designed temperature control system based on PLC. In the industry control equipment, temperature control absolutely decides product quality. Introduces a temperature control system based on EJ1 temperature control module that product by OMRON company, industry control computer communicates with PLC through Ethernet. And program on the VC++ flat, establishes man-machine friendly intercommunion interface, sets the temperature of each temperature and realize Real-time monitoring.
