The present application relates to a kind of multi-point cooperative gas emergency shutdown positioning method based on gas monitoring system, belong to the field of automation control technology. Among them, the method includes: real-time acquisition multi-source alarm signal;And the analog quantity and switch quantity of the multi-source alarm signal are uniformly converted into digital processing code;Multi-source alarm signal digital processing code is analyzed in real time to obtain alarm priority and associated equipment address, and data accuracy is verified by actual combat coefficient correction model;Combining dynamic networking and cooperative decision mechanism generates shutdown path;Shutdown path is executed, and execution result is fed back to host computer monitoring platform in real time, and field alarm lamp state and broadcast system are updated simultaneously;Through host computer monitoring platform, alarm history curve, equipment state and linkage logic of shutdown operation are recorded, and manual reset interface is provided to remove shutdown state. Efficient processing and accurate response of gas leakage accident are realized.
