| 摘要: |
| 针对目前对集中供热锅炉控制中没有远距离控制的现状,基于西门子S7-200系列可编程逻辑控制器PLC(ProgrammableLogicController)设计了一种集中供热锅炉自动控制系统,介绍其工作原理:控制现场传感器标准信号经过信号调理模块送到现场控制单元PLC,控制单元通过以太网相连,将需要监控的信号送入上位机,实现人机交互和远程控制。对系统的控制核心S7-200作了详细的介绍,并给出了软、硬件结构设计方案。 |

| Abstract: |
| Aiming at the absence of remote control for central heating boiler,an automatic control system based on S7-200 series PLC(Programmable Logic Controller) is presented.Its functions and features are discussed,and the working principle is introduced:standard signals from site transducers are transmitted to the locale control unit through signal processing module.Control units connect with Ethernet and monitored signals are sent to the superordinate computer for remote control and human-machine interface.The control kernel S7-200 is introduced,as well as corresponding hardware and software designs are offered. |
