Abstract

The invention discloses a shield door fault prediction method and device, terminal equipment and a storage medium. The method comprises the steps: acquiring characteristic parameters of a relay of a to-be-predicted shield door; inputting the characteristic parameters into a preset relay fault prediction model so as to enable the relay fault prediction model to predict the total pull-in frequency of the relay when the relay coil breaks down and the total pull-in frequency of the relay when the relay contact breaks down, and obtaining the first pull-in frequency when the relay coil breaks down and the second pull-in frequency when the relay contact breaks down; and according to the first pull-in frequency, the second pull-in frequency and the daily pull-in frequency of the relay, calculatingthe service life of the relay from the beginning of use to the occurrence of a fault, and then according to the service life of the relay, obtaining the service life of the shielding door from the beginning of use to the occurrence of the fault. By implementing the embodiment of the invention, the fault of the shielding door can be predicted in advance.

Description

Technical field [0001] The present invention relates to the technical field of screen door processing, in particular to a method, device, terminal equipment and storage medium of a screen door failure prediction. Background technique [0002] In the early construction process of urban rail transit stations, the main purpose is to achieve functions, and the reliability and safety of the equipment are less considered. The priority level of availability is higher than that of safety and reliability, so there is greater safety Hidden dangers. [0003] At this stage, the station data management system of rail transit is stored in the form of a database. But the stored historical data is only used for viewing and monitoring. It is not applied to risk prediction. Rail transit equipment, such as the screen door in the subway, will only alarm when a failure occurs, and it is impossible to predict when a failure occurs. The relay in the screen door is the component with the highest probab...
