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.
