Image-based Monitoring System for Switch Point Closure of High Speed Railway

In view of the difficulties in monitoring the closure state of switch point of high speed railway in China, an image-based monitoring system for switch point closure is developed. Based on the analysis of existing monitoring methods and with the introduction of advanced technologies such as learning algorithm and cloud computing into the traditional machine vision technology, the paper designs a closure monitoring algorithm based on edge recognition of switch point, puts forward the architecture of the monitoring system and verifies the accuracy of the monitoring algorithm through field tests. The test results show that the system notably improves the monitoring efficiency and accuracy of switch point closure compared with the existing monitoring methods, thus reducing the accident risk caused by the failure of switch point closure.
