Abstract:

The point switch has the responsibility of switching,blocking and monitoring the electrical devices on the railway.Its monitoring is of great significance to the safety of the railway operation.Most of the existing switch point monitors have the disadvantages of backward monitoring,high wrong warning rate and not being directviewing.By analyzing the problems in the existing switch monitoring system,this paper proposes an online video switch monitoring system.The monitoring system in the switch can capture the photo of the gap and upload the pictures in real time.The computer in the monitoring room can receive,identify,and automatically monitor the pictures.When the gap is lager than the standard value,there will be an alarm.This article also introduces the design and implementation of the image collection module.
