Gas turbine flowmeter fault identification method and system

The invention discloses a fault identification method and system for a gas turbine flowmeter, and relates to the technical field of flowmeter fault identification, and the method and system can collect and record the change trend information of related output signals obtained by the gas turbine flowmeter in real time through a real-time information monitoring module and system, and achieve the real-time monitoring of the state of the flowmeter. And a plurality of groups of sensors are used for monitoring operation state information and reading information of related mechanical parts in the gas turbine flowmeter, a complete flow database is established, and comprehensive monitoring of various parameters of the flowmeter is further realized. The fault analysis module obtains multi-dimensional fault features through feature extraction of data in the flow database, achieves accurate recognition of flowmeter faults and comprehensively obtains a risk assessment index Fgzs, and the system can further accurately asse
