摘 要 关键词： Abstract In recent years along with computer penetration in the social sphere, SCM applications are constantly deepening, and drives the transmission control system of detecting change rapidly.In real-time monitoring and automatic control of the SCM application system, the microcontroller is often used as a core component, only SCM knowledge is not enough, should be based on specific hardware structure, and the specific characteristics of the target application software, to make perfect. the refrigerator is essential in the modern family home appliances. But at present our country market selling refrigerators mostly using the traditional mechanical type temperature control, the control precision, single function, has the advantages of simple control method is difficult to meet the requirements of the development of refrigerator. With the economic development and peoples living standards further improved, the multifunctional development of increasingly high demand. As the MCU performance is good, strong control function, reliable work, low cost and other advantages, is now in the home appliance products has been widely used. Facing the domestic refrigerator development present situation, the technique is compared with other developed countries have a certain gap, we in the original basis of the refrigerator is improved, making it suitable for use in contemporary fashion, energy saving and environmental protection, intelligent, precise temperature control of the development mode, make people experience have never even heard of it personalized feeling, fast and the original is no longer a dream. A new generation of products in control also increased in artificial intelligence, is home appliance of superior performance, the use of more convenient and reliable. Refrigerator temperature control system is the use of temperature sensor acquisition of refrigerator and freezer room temperature and evaporation temperature.Through the use of MCU in digital signal proc
