基于ARM9的转辙机缺口监测图像采集模块设计

转辙机是铁路上负责道岔的转换、锁闭、监督功能的电气设备,它的监测对维护列车安全运行具有重要意义。现有道岔转换设备缺口监测系统存在检测方式落后、不直观、高误警等情况。针对上述情况文中提出了一种在线视频监控自动处理系统,其中转辙机内监控系统能对缺口图像的动态实时情况进行拍照和上传;工作室终端电脑能对道岔转辙机内表示杆缺口偏移量的图像进行识别、自动监测和超值报警,并介绍了图像采集模块的设计与实现。

Design of an Embedded Point Switch Video Monitor Based on ARM9

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.
