Fuel gas on-line monitoring and warning system and detection and control method thereof

Abstract

The invention relates to a detector terminal and an urban gas on-line real-time monitoring system which are independently researched and developed. An on-site terminal detector is employed to acquire the concentration of fuel gas around a gas transmission station in real time, and transmits data to a sub-station in real time wirelessly, the acquired data is analyzed and predicted by means of a Bayes algorithm, the data trend is compared and analyzed, the current fuel gas equipment state is judged, and the processed result is sent to a master station and a mobile phone of a worker; a scheduling mode based on cyclic polling and interrupt nesting is employed, when it is detected that data obviously rises or when master station polls, a slave computer has no response, the system carries out multitime enquiry in a targeted manner, the current fault reason is determined, a warning signal is sent to the master station timely, and false alarm is avoided. The master station can further analyze the decision layer through data in dependence on a fusion technology, a state change curve is fit, and the information prediction correct rate is ensured. The terminal, the sub-station, the master station and the user of the mobile phone can carry out communication and control timely and form a system independently.

Description

Technical field [0001] The gas online monitoring and early warning system and detection control based on multi-point fusion technology and Bayesian algorithm are dedicated to the online real-time monitoring and management of urban gas transmission stations. Background technique [0002] At present, natural gas has spread to every household, a large number of markets have made competition fiercer, the quality of household gas appliances cannot be guaranteed, and the long-term use of equipment, such as aging and corrosion, often lead to a series of problems such as easy gas leakage; and my country Insufficient investment in natural gas technology and technology, backward equipment, slow development of the supply and distribution system, and not up to international standards. There is a big gap between the online real-time early warning control methods of gas and foreign countries. The gas network system has been initially established, and a good urban gas information system urgently...

AI Technical Summary

Problems solved by technology

The reliable supervision of urban gas is closely related to everyone's safe life. Once the gas leaks and an explosion occurs, it will not only cause serious property losses, but may even cause personal casualties.

However, the current supervision methods for urban gas are relatively limited, and they mainly rely on their own management and maintenance. It is inevitable that there will be negligence, and there is no online monitoring and early warning measures for real-time closed-loop control methods.
