Aiming at the problems such as the temperature control technology＇s lagging behind,its low efficiency and so on, multiplex temperature controller based on single chip microcomputer is designed. It takes single chip microcomputer AT89C51 as the master control chip and takes DS18B20 as the signal transducer. In this paper, the function module of the system is described in detail. The system module mainly includes master control module, temperature acquisition module, human computer interaction module, sound and light alarm module and heat and cool control module. At the same time, the hardware system and software system design are described in detail. Finally, the system simulation experiment is carried out, and the expected function of the system is realized basically. Multiplex temperature control system is simple and has strong anti-interference ability, so it has a certain value and application prospect.
