Application Of Switch Machine Gap Video Monitoring System In The Existing Railway Line

Switch plays an important role in railway line, so switch machine is the core equipment of switch control system. The interlocking equipment, switch machine is the role after receiving the order driven switch, its main function is to: conversion turnout, turnout locking switch rail, said the location, is the core part of the turnout. In change trains running lines, confidential in accordance with the switch train running line drives convert a bit ahead of turnout. Therefore, the working performance and quality of switch machine, directly affect the turnout can normal conversion, is to ensure the normal railway equipment in railway transportation.According to the working principle of switch machine, switch machine indication notch position is normal or not is the key factor of switch machine can work normally. At present, said the gap position check test mainly depends on the signal maintenance personnel at the scene to directly measure equipment of switch machine, minimal use of real-time video monitoring system. At the same time, the switch machine representation gap position monitoring mostly adopt touch bead type and photoelectric type, and the use of image recognition technology watch less. With the development of image recognition technology and the development of camera performance, image recognition technology has many obvious advantages.From the basic knowledge of switch machine and the existing switch machine structure principle of the domestic gap switch machine monitoring method and foreign contrast, can very clearly shows the advantages of image recognition technology. Based on video image processing technology research are as follows: first using image processing technology for the position of the hole of recognition and measurement, and then through the image brightness, denoising processing, then the obtained data and set the standard are compared with each other, from real and reflect the switch machine gap state. In general, the switch machine gap video monitoring system can better meet the switch machine gap position real-time monitoring of this requirement. Finally, through the switch machine gap video monitoring system in the part of Longhai line stations use and maintenance for the switch machine gap video monitoring system in the promotion of the existing railway lines to provide data support and use experience; at the same time, for the use of problems appeared in the process of research and improvement to further development of video monitoring system lay the foundation.
