摘要
为了在列车自动保护系统(ATP)失效的状态下,还能为地铁车辆提供最后的安全保护,本文采用了符合国际标准ISO15693的13.56MHz射频识别(RFID)技术,设计并实现了一套独立于ATP的紧急停车系统(ESS),通过安装在车底的天线对安装于轨道内的标签完成识别,进而触发紧急制动回路断开,确保车辆安全停止于轨道末端之前。该系统通过了运行试验和现场鉴定,可以满足在恶劣环境下的车辆可靠识别和安全停车,确保乘客的生命安全。
In order to proyide the security protection for metro vehicles in the case of Automatic Train Protection （ATP） system failure. A set of emergency stop system （ESS） which is independent of the ATP system is designed and implemented. The Radio Frequency Identification （RFID） technology of 13.56MHz which meets the international standard ISO 15693 is used. Antenna is installed on the bottom of the vehicle to recognize the identification label inside the track, and thus triggers the emergency brake circuit disconnected to ensure the safety of vehicles to stop before the track ends. This system has passed the running test and the on-site identification. It can achieve reliable identification of the vehicle and secure brake in the harsh environment, to ensure the safety of the passengers.
