| Today the data collecting and equipment monitoring of DCS are connected via cables, this confines the use area and space distance of DCS: Whole connected by cables restricts the application of DCS in some exceeding environment, for example, using cable in exceeding cold,exceeding hot or exceeding humidity will clearly reduce system security. Making use of wireless technology in DCS carries out data collecting and equipment controlling, it can reduce invest and advance performance. DCS based on wireless technology is better in system security,maintenance and function extend etc.This article analyzes the configuration and work principle of Automation System, home realize all kinds of wireless technology and their application; And the request of work environment and system technique of the Automation System based on wireless technique is explained, and a economic plan idea is given; And finally, the frame and work principle by Single closed-loop control system based on ZigBee are explained. Combining the work principle and environment of Single closed-loop control system, various device of Single closed-loop control system based on ZigBee are chosen, and functions of various devices are explained; a projection of devices choosing of Single closed-loop control system based on LPC is put forward; And according to the project,the system hardware and software is finished. |
