The invention relates to a marine vacuum pump station performance monitoring and fault diagnosis platform. An electronic flowmeter is arranged at the front end of a vacuum container, and a pressure sensor is arranged on the vacuum container; the electronic flowmeter monitors the suction flow of the vacuum pump station, and the pressure sensor measures the vacuum pressure value of the vacuum system; a shock absorber is arranged below the vacuum pump; four vibration accelerometers are respectively arranged above and below the shock absorber; a noise sensor is arranged on the vacuum pump; the center console collects analog quantity signals of the electronic flowmeter, the pressure sensor and the vibration accelerometer, sends a fault alarm signal to a superior system at the same time, draws a suction performance curve graph of the vacuum pump and is used for vacuum pump vibration noise monitoring and vacuum pump station fault diagnosis. The method is used for monitoring the suction performance level of the vacuum pump station in real time and analyzing deviation from a standard curve; fault information of the vacuum pump is diagnosed and recorded; signals are remotely transmitted to a superior system, so that sailors can conveniently use and maintain the vacuum pump station.
