Oil and gas production instrument fault diagnosis method, device, equipment and related system

The invention discloses an oil and gas production instrument fault diagnosis method, device, equipment and related system, and the method can comprise the steps: carrying out the abnormal value checking of received instrument data, so as to determine whether an instrument is normal or not; if yes, whether the instrument breaks down or not is judged based on a preset instrument data threshold value; if not, the instrument data are input into a pre-trained recurrent neural network model, and the probability distribution of the instrument data output by the recurrent neural network model and historical data is determined; and diagnosing whether a fault occurs based on the probability distribution. According to the method, diagnosis of various common faults of the oil and gas production instrument can be realized, and the confidence probability of a fault diagnosis result is given; furthermore, the method has better generalizability, and can be realized by establishing a data interface with an oil field digital s
