基于PID控制理论和步进电动机的冬季室内温度控制系统设计

摘要

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，来控制阀门的开度，调节暖气管道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 usual y adopts the centralized heating and users can not control temperature by themselves. As a result, indoor temperature is too high which 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 control ing valves according to the real-time measurement of the indoor temperature. In this way, indoor temperature can be control ed. People wil live in a more comfortable environment. At the same time, energy is saved.
