Objective： Automatic chemiluminescence immunoassay analyzer has a precise requirements of temperature at its incubate slot, in order to solve the problems of low precision and difficult control appeared in traditional Automatic chemiluminescence immunoassay analyzer instrument. Methods： A temperature control module of automatic chemiluminescence immunoassay analyzer is designed and implemented based on the master chip STC89C52 and the temperature sensor DS18B20. Choose a more streamlined design, hardware and software solutions, use of simulation software Proteus simulation, and design the hardware model. Results： so that the reaction zone incubation tank temperature precise control at 37℃, accuracy of 37±0.3℃. Conclusions： Microcomputer plays a vital role in the development of intelligent equipment. And MCU owns the characteristics of practical and easy development. So the design of temperature control module based on MCU has more preponderance of low cost, strong practical, reliable control.
