Abstract:Chinese northern cities commonly adopt the central heating in winter.However,since the heating systems are not equipped with automatic control devices,the efficiency of heating systems is low. A control system based on STC89C58R for home heating station was designed to solve this problem. The system can adjust the room temperature using PID algorithm in different model sand provide domestic hot water at the time.Finally, a matlab simulation and prototype debugging of the system were implemented, and observed the running time on the oscilloscope,the result showed that the system can run in accordance with requirements.
