摘　　要：针对目前农业的发展由粗放型向节约型转变的需要,设计一套以AT89C52单片机为核心,与外围器件数字温度传感器DS18B20、数码管、按键、电风扇和加热片共同构成的温度监控系统。该系统能够根据实测温度偏离设定温度值的程度由单片机驱动继电器自动启动相应的加热和降温设备,实现对设定参数的闭环调节,从而将温度保持在恒温,较大程度上节约农业生产人力资源。经实验验证,该系统具有较高的测量精度和控制精度。To meet the needs of the current agricultural development changing from extensive type to saving type, this paper designs a set of temperature monitoring system with AT89C52 microcontroller as the core, which is composed of peripheral digital temperature sensor DS18B20, digital tube, keys, electric fan and heater. The system can set temperature value degree according to the measured temperature deviation and can be driven by SCM relay autostarting corresponding heating and cooling equipment to achieve the regulation of the closed loop of the parameters, and the temperature is maintained constant which largely save human resource and agricultural production. Experiments shows that this system has higher measurement and control precision.
