摘　　要：在我国北方,冬季取暖一般采用暖气技术集中供暖,用户不能自主地调节温度,室内温度过高,资源浪费的现象严重。本设计应用PID控制技术,以步进电动机作为执行元件,根据实时测量的室内温度,来控制暖气片上阀门的开度,调节暖气片内热水或热气的流量,从而达到了控制室内温度的目的,增强了居民室内生活的舒适度,减少了能源的浪费。In the north of China, winter heating technology usually adopts the centralized heating and users can not control temperature by themselves. Thus, indoor temperature may be too high it results in a serious waste of resources. The design adopts PID control technology and uses a step motor as the actuator. The design can change the flow of hot water or gas in pipes by controlling valves according to the real-time measurement of the indoor temperature. In this way, indoor temperature can be controlled. People live in a more comfortable environment. At the same time, energy is saved.
