Safety detection method, device and equipment for single-point levitation system of maglev train and medium

Abstract

The invention discloses a potential safety hazard detection method and device for a single-point levitation system of a maglev train, electronic equipment and a readable storage medium. The method comprises the following steps: respectively acquiring multi-dimensional sensor data of a to-be-tested maglev train under various loads; for each dimension of sensor data, calculating probability distribution information of the current dimension of sensor data at an initial moment and a current moment to obtain initial probability distribution and current probability distribution; calculating the distance between the initial probability distribution and the current probability distribution, and calculating the weight of the distance corresponding to the sensor data of each dimension; for each single-point levitation system, calculating the weight sum of the distance corresponding to each dimension of sensor data in the current single-point levitation system, and taking the weight sum as the weight of the single-point levitation system; and determining whether the to-be-detected maglev train has potential safety hazards based on the weight of each single-point levitation system so that the detection accuracy of the potential safety hazards of the single-point levitation systems of the maglev train is improved.

Description

technical field [0001] The present application relates to the technical field of safety monitoring, in particular to a method, device, electronic equipment and readable storage medium for detecting potential safety hazards of a single-point suspension system of a maglev train. Background technique [0002] Each train of the maglev train has 20 single-point suspension systems. During the operation of the maglev train, each single-point suspension system has alternating loads such as load, track irregularity, and speed, as well as the risk of rail resonance caused by the train and the track. Under the action of alternating loads, the performance of the single-point suspension system is degraded, which leads to the deterioration of the sensor data of the suspension system. At the same time, under alternating loads, when the performance of the maglev train is degraded, the sensor data of the suspension system at the corresponding position will change to a certain extent, resulti...

AI Technical Summary

Problems solved by technology

When the data collected by any sensor exceeds the threshold, it is determined that there is a single-point suspension system with potential safety hazards

Although the single-point suspension system with obvious safety hazards can be detected, under alternating loads, when the performance of the single-point suspension system is degraded, the accuracy of the sensor data of the corresponding position of the single-point suspension system is poor, but it does not exceed the threshold , which will lead to false negatives, making it impossible to detect single point suspension systems that may have safety hazards
