摘要
研究了以下位机S7-300系列PLC和上位机WinCC为核心的供热控制系统。其硬件主要由SIEMENS S7-300PLC、MM430变频器组成,完成变频恒压供水的控制任务和现场的数据采集。并由WinCC6.0组态软件完成系统的监控。实际运行表明,该系统提高了供热水系统的稳定性与可靠性,减轻了工人劳动强度,实现了节能降耗。
The heating control system which uses S7-300 as subordinate computer and WinCC as supervisory computer is introduced.Its hardware consists of SIEMENS S7-300 PLC and MM430 converter to fulfill the task of variable frequency constant pressure water-supply and field data collection.Industry supervision software WinCC 6.0 can achieve the task of monitoring.Practical operation demonstrates that the stability and reliability of the water supply system have been improved and the labor intensity of workers is reduced.The purpose of saving energy and reducing consumption has been realized.
