摘　　要：本系统以AT89S52单片机为中心控制器件,主要由温度传感电路,A/D转换放大电路,单片机编程电路,显示电路,控制电路等部分组成。温度信号由温度传感器AD590采集,经过放大转化为电压信号进行编码,测温分辨率0.1℃。水温实时控制由继电器电热丝和风扇进行升温和降温。显示部分由"人机交互界面"的12864液晶显示,增加可读性。该系统具备较高的测量精度,能较好的完成设计要求。The temperature control system,which is regarded as the central control device of AT89S52 microcontroller,is constructed by the temperature sensing module,A/D converter amplifier module,control module,microcontroller programming module,display module and other components.Temperature signal is collected byte AD590 temperature sensor which is amplified into a voltage signal is encoded,temperature resolution is 0.1 ℃.Real-time control temperature can be heated by heating wire and electric fan.Display part is quoted by ＂man-machine interface＂ of 12864 LCD to increase the readability. The system features is of high accuracy,and it can have better complete of the design requirements.
