The invention provides a rail transit equipment state prediction method and device, equipment and a storage medium. The method comprises the following steps: acquiring monitoring data of target equipment in a preset time period; wherein the monitoring data comprises sensing data of the target equipment and sensing data of an external environment of the target equipment; according to the to-be-predicted state of the target equipment, a feature data set is screened out from the monitoring data, and the feature data set is a set of the monitoring data of which the relevance with the to-be-predicted state of the target equipment reaches a preset range; processing the feature data set by using a prediction model to obtain a prediction result corresponding to the to-be-predicted state; wherein the prediction model is constructed based on a random forest regression algorithm.
Description
technical field [0001] The invention relates to the technical field of intelligent operation and maintenance of urban rail transit, in particular to a state prediction method, device, device and storage medium of rail transit equipment. Background technique [0002] Urban rail transit, led by subway, is developing rapidly in my country, and rail transit has become an important part of urban construction in my country. According to the "2020 Overview of Urban Rail Transit Lines in Mainland China" released by the China Urban Rail Transit Association, as of December 31, 2020, the total mileage of urban rail transit in my country was about 7,978km, with 45 cities open to traffic, with a total of new operations. The mileage of the line is about 1241km, and 36 new operating lines are added. With the continuous increase of new lines in various places, the number of related equipment has increased greatly, and the facility equipment system has suffered a heavy load. [0003] At pre...
