摘　　要：针对目前温室中人工控制热水采暖面临的问题,设计开发了基于单片机测控温室内温度的热水采暖系统。该系统以单片机AT89S52为核心,利用温度传感器DS18B20、D/A转换器TLC5615、电动调节阀等实现对温室内多点位温度的测控。试验结果表明,该系统操控简单,能够精准调控温室内温度,并具有较高的稳定性。In view of the problems facing with the artificial controlled hot water heating in the greenhouse, a temperature control system for hot water heating based on single-chip microcomputer was designed. The AT89S52 was used as the kenel component of this system, and a temperature sensor DS18B20, D/A transfer TLC5615 and electric control valve were employed to control temperature in the greenhouse. The result showed that this system was easy to control. Meanwhile, it was provided with high precision and stability.
