Abstract

The invention provides a hydraulic turbine set remote listening monitoring method, device and system. The method comprises the following steps: acquiring an original audio signal of a preset duration; performing data noise reduction on the original audio signal to obtain a target audio signal; performing characteristic extraction on the target audio signal to obtain a target characteristic value; and inputting the target characteristic value into a target fault model for fault detection to obtain a detection result of the original audio signal. Therefore, the problem that in the prior art, sound characteristics cannot be monitored or judged when the hydraulic turbine set runs is solved, on-site sound is analyzed and processed on line through the audio analysis technology, the remote listening of the hydraulic turbine set is achieved, and the requirement for monitoring the running state of the hydraulic turbine set is met.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method, device and system for remote listening and monitoring of water turbine units. Background technique [0002] At present, the monitoring and fault diagnosis technology for the operation status of the hydraulic turbine unit mainly obtains the data of various indicators during the operation of the unit in real time through the current, voltage, vibration, air gap and other sensors deployed on site; on this basis, through data processing and analysis Algorithm, real-time analysis of equipment status to ensure the reliability of unit operation; therefore, in terms of hydroelectric unit status monitoring, the main technical means is to rely on computer monitoring Such sensors and cameras collect on-site data to realize "telemetry", "remote signaling", "remote adjustment", "remote control" and "remote viewing". [0003] However, for system supervisors, the monitoring ...
