【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。更多还原

【Abstract】 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.更多还原
