Fault detection method, device, equipment and medium of pressure wave sensor in train

Abstract

The application discloses a fault detection method, device, electronic equipment and computer-readable storage medium of a pressure wave sensor in a train. The method includes: obtaining the train speed; judging whether the speed is less than a preset speed threshold; if so, judging the speed Whether it is less than the preset shielding threshold; if the vehicle speed is less than the preset shielding threshold, then obtain the differential pressure detection value of the pressure wave sensor, and judge whether the differential pressure detection value or its rate of change exceeds the preset range, and if so, determine that the pressure wave sensor is faulty ; If the vehicle speed is not less than the preset shielding threshold, it is judged whether the cumulative activation duration of the pressure wave train line activation signal of the train exceeds the preset duration, and if so, it is determined that the pressure wave sensor fails. The application effectively solves the fault detection problem of the pressure wave sensor when the differential pressure detection value does not exceed the range range, improves the fault detection accuracy of the pressure wave sensor, and ensures the safety of train running.

Description

technical field [0001] The present application relates to the technical field of electronic equipment detection, and in particular to a fault detection method, device, electronic equipment and computer-readable storage medium for a pressure wave sensor in a train. Background technique [0002] During the running of the train, in order to ensure the safety of the system equipment and the physical comfort of the passengers, it is necessary to make timely and appropriate adjustments according to the pressure wave changes on the train. Therefore, pressure wave sensors are installed on the train to detect the pressure difference inside and outside the train, so that The train controller automatically activates the pressure wave train line activation signal when the pressure difference detection value of the pressure wave sensor is large, that is, closes the new damper of the entire train air conditioning system to maintain a constant pressure difference inside and outside the trai...

AI Technical Summary

Problems solved by technology

[0003] In the related art, when judging whether the pressure wave sensor is faulty, the pressure wave sensor is judged to be faulty only when the detection value of the pressure wave sensor exceeds the range of the sensor. Failure of the pressure wave sensor and the discrepancy between the readings of the sensor and the actual situation may occur, which may cause abnormal activation of the pressure wave train line signal, resulting in insufficient fresh air in the train, reducing the ventilation, cooling and heating efficiency of the train air conditioner and increasing energy consumption; Serious consequences such as lack of oxygen in the train and suffocation of passengers will affect the safe operation of the train
