Railway external environment hidden danger detection and management method based on space-air-ground integration technology

Abstract

The invention discloses a railway external environment hidden danger detection and management method based on space-air-ground integration technology. The method comprises the following steps: S1, making basic data of a railway external environment detection platform based on map service; s2, establishing a railway external environment potential safety hazard database based on a spatial information technology; s3, fusing the two libraries; s4, deploying the platform; s5, regularly detecting a railway external environment potential safety hazard target based on a spatial information technology;s6, carrying out hidden danger target OA closed-loop management based on a railway external environment detection platform; and S7, carrying out hidden danger target analysis and management based ona railway external environment detection platform. According to the method, space remote sensing technology detection is mainly adopted; targeted recheck and problem disposal are carried out in cooperation with manpower, high automation from data acquisition to detection result output is realized, the operation efficiency and informatization degree are improved, and fine management and analysis ofthe detection result and closed-loop management from hidden danger discovery, field recheck, information filling and reporting to hidden danger OA processing are realized.

Description

technical field

[0001] The invention belongs to the field of railway operation maintenance and management, in particular to a method for detecting and managing hidden dangers in the external environment of railways based on air-space-ground integration technology. Background technique

[0002] The safety management of railway external environment is one of the important contents of railway operation and maintenance. With the continuous increase of the mileage of normal-speed railways and high-speed railways in my country, it is inevitable that there will be a sharp increase in human activities in the surrounding areas of railway transit. big security risk. In 2018 alone, there were more than 3,000 incidents of delays in railway traffic due to surrounding color steel buildings falling onto the line, which led to a sharp rise in the importance of the detection and management of the external environment of the railway. At present, the external environment detection of railways...
