摘要
利用单片机技术实现对温室内多点温度进行采集、处理及调节。通过温度传感器将非电量的温度值转换为电量输出 ,由A/D转换器对模拟信号进行数字化 ,经单片机处理后送显示器及执行机构 ,对温室内地下热交换系统。
By the technique of single-chip computer Mcs-51 the greenhouse temperature at nine sites was sampled with sensors and then was processed. The regulating equipments in the greenhouse including hot-exchanging electric fans, electric fans and hot-excluding electric fan were controlled automatically. The temperature in the greenhouse can be adjusted to meet the need of the crops.
