Semiconductor Refrigeration Intelligent Control Based On Single Chip Microcomputer

With the development of semiconductor materials and related to areas of demand, more and more use of semiconductor refrigeration or power generation device entered the industrial production and People’s Daily life. Semiconductor refrigerator is a device that use peltier effect for refrigeration, it has small volume, light weight, long service life, no noise, no mechanical movement, rapid heating and refrigeration, high control precision, don’t need refrigerants, no pollution.Semiconductor refrigeration based on single chip microcomputer intelligent control system mainly realize the role of the sealed box body temperature constant, mainly used in the single-chip microcomputer, temperature sensors, signal driver circuit, digital tube display circuit, semiconductor refrigeration device. At the same time, based on single chip microcomputer and computer serial port communication, on the basis of the single chip microcomputer and computer real-time communication.This design with the single chip processor as the processing center, receive the feedback signal from the temperature sensor, through the single chip microcomputer fuzzy control algorithm to deal with internal, output a certain duty ratio of PWM signal, passes through the drive function, finally drive semiconductor refrigeration cooler. And through the way of manual control or automatic control, control of semiconductor refrigerator refrigeration power, achieve the goal of controlling temperature.
