Design and application of servicing vehicle operation safety monitoring system for urban rail transit
At present,urban rail transit servicing vehicles are generally not equipped with operation safety protection equipment,and safety control is mainly realized by the driver's visual observation and artificial judgment in the process of driving and operation on the main line and in depots.There are lacks of technical protection means such as signal duplication,voice reminder,automatic parking,etc.In operation,the servicing vehicles have the risk of overspeed and overrunning signals,leading to accidents such as derailment and turnout splitting from time to time.To solve such issue,this article designs a set of operation safety monitoring system for urban rail transit servicing vehicle,and elaborates its system function,working principle,and control mode in depots and on the main line.In order to verify the actual effect and performance of the system,it is installed in Guangzhou metro line 7 trains,and the verification results show that the system can meet the safety protection and monitoring requirements of urban rail transit servicing vehicle.
