摘要
针对热处理电炉温度控制的工艺及控制要求,设计了一种利用RS-485总线将工控机和各种智能控制器互联,构成的经济实用、性能可靠的温度网络控制系统。为提高生产效率及控制水平、降低劳动强度,具体介绍了其硬件组态、网络互联及网络通信的设计与实现。
To enhance the heat-treatment plant automation and reduce the labor expenses ,we have successfully designed a economical, practical and reliable distributed control System, which uses RS-485 bus to connect the IPC and intelligent controllers.The article also introduced the construction of this system, and the implementation of the system＇ s communication network.
