摘要
本文介绍了太阳能热水工程监控系统的设计要求以及原理。利用三维力控组态技术设计出一套太阳能热水工程的监控系统。本监控系统以PC机作为上位机,可编程控制器PLC做为下位机,利用RS-485通信技术组网,实现了上位机与下位机的通信,实现数据的传输,将数据显示与存储于上位机中。
The article introduced the design requirements and principle of monitoring system used PLC and PC-Auto.This monitoring used PC as epigyny computer, PLC as hypogyny computer,used net of RS-485 to realize communication of epigyny computer and hypogyny computer, realized data transmission.
