Tramcar closed circuit television monitoring system and implementation method thereof

Abstract

The invention discloses a tramcar closed circuit television monitoring system and an implementation method thereof. Based on a tramcar travelling automation system platform, the linkage and data sharing of a tramcar closed circuit television and a train monitoring system are realized, by an audio frequency automatic switching technology, the functions of automatic drawing, function transferring, alarming and the like on a control centre CCTV work station are realized. According to train position message sent by an ATS, when the train achieves one station or runs through a grade crossing, the ATS server sends a train arriving or approaching grade crossing message to the CCTV server through a central local network, the CCTV server controls a camera image of the audio frequency display workstation to be automatically converted to a group of predetermined camera information of the current station. The implementation method not only can realize the timeliness of operation response, but also can meet the subsequent requirement of the system, and can realize the linkage function of the closed circuit television and the train monitoring system stability and efficiently, thereby improving the reliability and stability of the system.

Description

technical field

[0001] The invention relates to tram driving automation technology, in particular to a tram closed-circuit television monitoring system and a realization method thereof. Background technique

[0002] Modern trams are based on urban roads, mainly laying tracks on the ground, using electric traction, low-floor trams, operating in the form of partial independence or complete sharing of road rights, manual driving, and signal priority control. In addition, the construction concept of trams is often imprinted with subway and light rail technology.

[0003] The video surveillance system is an important means of maintaining urban trams and ensuring transportation safety. It can provide dispatchers in the control center with public security information on train operation, fire prevention and disaster prevention, passenger guidance, and social security. The closed-circuit television monitoring system is the modernized supporting equipment for tram operation and manag...
