Abstract
In view of the explosion danger in process engineering, this article combined with the automatic control technique and the intelligent sensor techniques, computes the explosion limit and limits oxygen concentration, then designed a set of automatic alarm-control system for Burning Mixture Oxygen Concentration Detection which based on KY-2F Oxygen Sensor, ZBWJ-90SIEMENS Gas Flowmeter and SIMATIC S7-300 PLC. It introduced the software designing, hardware composition and working principle of the system in detail. According to the practical situation and the calculated limit oxygen concentration, the system set the alarm threshold of oxygen concentration and the control threshold of solenoid valve. According to the oxygen concentration of the burning mixture in reactor by the software design of PLC, it can realize the function of dection, alarm and controlling, which provides a reliable technical support for the safety protection of the burning mixture in the process engineering.关键词
