The design of the pulsating vacuum sterilizer control system taking microcontroller STC89C52 as the core is de- scribed. The realization principle, the hardware components and software design of the system are introduced. Fuzzy-PID mixing al- gorithm is used to carry out the nonlinear control of temperature in the sterilization process. It is easy to realize the automation con- trol of the pulsating vacuum sterilizer by the intelligent software of the system. The system has the characteristics of real-time param- eter display and graphical display in sterilization process, and also has the functions of storing and printing all the needed parame- ters. The software and hardware anti-jamming measures are adopted. The experiments show that the system has multiple functions, strong practical applicability and safe operation, can improve the control accuracy and realize process automation of sterilizer.
