TemperatureControlSystem
本系统严格按照题中所定参数及要求，构建了一个以MSP430单片机为控制核心的温度自动控制系统。该系统用PSB型负温热敏电阻作为温度传感器，以一种类R-F的方法测量木盒内实时温度，单片机用实时温度与预设温度值一起代入PID算式得出一个温度增量，再用此温度增量线性的控制PWM波的占空比，开关电源的输出电压也会随之变化，即制冷晶片的输入功率发生变化，因此制冷晶片制冷（加热）的功率随PWM波占空比变化，达到自动控温的目的。本系统制冷（加热）效果明显，效率高，界面友好，制作精致，能够胜任题中所定各项要求。(Question in strict accordance with the system parameters and requirements set out to construct a MSP430 microcontroller to control the core temperature control system. The system with the PSB-type negative thermal sensitive resistors as temperature sensors, the method in a class of RF real-time measurement of temperature inside the wooden box, single chip with real-time temperature and the preset temperature value into the PID formula come together on behalf of a temperature increase, then this temperature increment linear wave PWM duty cycle control, switching power supply output voltage will change, that is cooling the chip input power changes, so cooling the chip cooling (heating) power with the PWM duty cycle changes in wave to achieve the purpose of automatic temperature control. The system cooling (heating) effect is obvious, efficient, friendly interface, making sophisticated, capable of the requirements set out in the title.)
