So will make temperature electric blanket really leave home controller, is very necessary to design a good temperature control and controller to control, meet the public in the safe, comfortable, convenient operation, etc. This design is based on51 single chip puter control, Can display the set temperature, heating time and the actual temperature of constant temperature electric blanket controller. This design uses AT89C51 as the traditional operas foot encapsulation so price only with cheap single chip puter. This design USES DS18B20 temperature is sensor. Temperature is control ed in the range of10℃ to50℃. The analog input voltage values into the corresponding temperature control of electric blanket constant temperature and room temperature display. In the whole design, I according to the system functional division of the subsystem structure, planning a
