Railway bridge and culvert height-limiting protection frame state monitoring system and method

Abstract

The invention provides a railway bridge and culvert height-limiting protection frame state monitoring system and method, wherein the method is applied to the system and comprises the steps: providing and collecting attitude information of a protection frame, environment information and image information near the protection frame; building a three-dimensional model of the protective frame, and performing attitude simulation by utilizing the built three-dimensional model of the protection frame according to the received attitude information; extracting vehicle information from the received image information when the simulation exceeds a threshold; and generating and issuing alarm information according to the simulation result of the protection frame and the vehicle information. The impact, posture and environment information of the left and right pillars of the height-limiting protection frame are detected, the influence of the impact on the postures of the pillars and a cross beam and the environment where the protection frame is located are evaluated, then the impact force and the bridge and culvert posture information are simulated, an alarm is given according to whether the impact force and the bridge and culvert posture information exceed preset threshold values or not, the automation degree is high, the collected data range is wide, and comprehensive monitoring of the height-limiting protection frame is realized.

Description

technical field [0001] The invention relates to the technical field of height-limiting protective frame monitoring, in particular to a state monitoring system and method for a railway bridge and culvert height-limiting protective frame. Background technique [0002] There are many fixed equipment and facilities along the railway line to ensure driving safety and line safety. With the increase in the operating mileage of my country's railways year by year, the bridge and culvert anti-collision beams along the iron-span highway along the railway line, the maintenance access doors along the closed railway line protection net, and There are many level crossings, such as level crossings, scattered locations, complex surrounding environment and difficult management. Once the fixed equipment and facilities on site lose their function, such as: cars impacting railway bridges and culverts and roadbeds, idlers intruding into the main railway line, and trucks impacting Major accidents su...

AI Technical Summary

Problems solved by technology

[0003] The anti-collision beams of railway bridges and culverts are damaged and cause damage to railway bridges and culverts from time to time. At this stage, the daily anti-collision beam inspection mainly adopts manual inspection. A lot of experience, and the daily small and medium-sized scratch incidents are even more ignorant; for railway crossings, etc., there is the same extensive management mode, usually a video surveillance system is installed, which can only be used as post-event analysis data for daily supervision needs It takes a dedicated person or a lot of manpower to analyze the video recording; the analysis efficiency is low, the intelligence is low, and the damaged information cannot be automatically reported

On the other hand, the evaluation of the damage caused by the impact is not accurate enough, resulting in misjudgment of the alarm signal. Based on this, it is necessary to provide a state monitoring system and method for the height limit protection frame of railway bridges and culverts.
