说明：  　　　本恒温箱温度的控制系统采用数字温度传感器DS18B20，该传感器将采集的温度转化为数字信号，经单片机MEGA16处理后，将测量得到的温度值和设定的温度值显示在液晶显示器1602上。系统的全部输入输出控制集中由单片机统一管理,各有关运行参数的设定根据增量PID参数设定，操作简单方便，从而实现平滑稳定的控制。
(The constant temperature box temperature control system USES the digital temperature sensor DS18B20, the sensor will be collected by temperature is converted into digital signals, the microcontroller MEGA16 after processing, will measure temperature and set temperature display on the LCD, 1602. All system input and output control centered by the single chip microcomputer unified management, the relevant operation parameters setting according to the incremental PID parameters setting, simple and convenient operation, so as to realize the control of smooth and stable. )
