Objective To develop the plasma sterihzation using H2O2 in low temperature. Methods According to the principle of plasma sterilization, the working process of the plasma sterilization using H2O2 in low temperature and its flow chart were designed. The requirement for system design was summarized, on the basis of which the structure frame was built up. The station diagram of movement of the gates controlled by PLD was put out by analyzing the process of their moving. The MCU acted as the main controller of the whole system. The action flow chart of the MCU controlling the process of the system was also given out. Results The process control in plasma sterilization equipment using H2O2 in low temperature achieved the stable running and low cost. Conclusion It is proved that this plan is feasible in implementation.
