摘　　要：针对部分居民小区及乡村居民无法集中供暖的现状,设计了基于PLC控制的家庭供暖系统。该系统以天然气为能源,以水为传热介质,由暖气炉、管道、电磁阀、人体红外传感器和散热器等部分组成。以西门子PLC S7-300为控制核心,对暖气炉的加热过程进行控制;使用辅助继电器来控制电磁阀及燃气阀,实现对环境温度的调节。设计中使用STEP7进行软件编程,并用MCg S软件进行了系统仿真。仿真结果表明,本系统能够达到较为理想的供暖效果。For the present situation of that part of the residential areas and the rural residents unable to enjoy central heating, the household heating system based on PLC control is designed. The system uses natural gas as energy and water as heat transfer medium, it consists of heating furnace, pipe, solenoid valve, the human body infrared sensor and radiator parts. The heating process is controlled by Siemens PLC S7-300; the auxiliary relay is used to control the solenoid valve and gas valve, to realize the adjustment of the environment temperature. STEP7 is used in the design of software programming, and the system simulation is carried out by MCGS software. The heating effect. simulation results show that the system can achieve the ideal
