The invention discloses a CBTC (Communication Based Train Control) backup point type temporary speed limiting method and system based on an access. The method comprises the following steps: an ATS (Automatic Train Control) issues temporary speed limiting information to a ZC.DS; the ZC.DS converts changed TSR information into TSR code bit information based on a corresponding route, and configures the TSR code bit information to a corresponding CBI; the CBI updates the TSR information, and issues the TSR code bit information containing the updated route information with temporary speed limit based on the route to an LEU; the LEU activates the corresponding temporary speed limit message content in a temporary speed limit message pool, and issues the temporary speed limit message to a corresponding European active transponder; the European active transponder sends a message containing the temporary speed limit information based on the route TSR to a vehicle-mounted VOBC of the passing train; and the vehicle-mounted VOBC analyzes the temporary speed limiting information in the message and controls the running speed of the train according to the temporary speed limiting information. The running speed of the backup point type train is greatly increased, and the running efficiency is improved.

    本发明公开了一种基于进路的CBTC后备点式临时限速方法及系统,由ATS下发临时限速信息给ZC.DS;ZC.DS将变更后的TSR信息转换为基于对应进路的TSR码位信息,配置到对应的CBI;CBI更新TSR信息,并将包含更新后基于进路的有临时限速的进路信息TSR码位信息下发给LEU;LEU激活临时限速报文池中对应的临时限速报文内容,并将该临时限速报文下发到对应的欧式有源应答器;欧式有源应答器将含基于进路TSR临时限速信息的报文发送给经过列车的车载VOBC;车载VOBC解析报文中的临时限速信息,并根据临时限速信息控制列车的运行速度。本发明大大提高了后备点式列车运行速度,提高运行效率。
