The invention discloses a voting system for rail transit data. The system comprises a first CPU used for sending a first voting frame of rail transit data to a first FPGA; the first FPGA is connected with the first CPU and the second FPGA and used for receiving a first voting frame from the first CPU and a second voting frame from the second CPU and generating a first voting result according to the first voting frame and the second voting frame; the second CPU is connected with the second FPGA and used for sending a second voting frame of the rail transit data to the second FPGA; and the second FPGA is connected with the second CPU and the first FPGA, and is used for receiving the first voting frame from the first CPU and the second voting frame from the second CPU, and generating a second voting result according to the first voting frame and the second voting frame. According to the method and the device, the technical problem of low CPU voting efficiency in related technologies is solved, and the response timeliness and the overall safety of the train control system are enhanced.

    本发明公开了一种轨道交通数据的表决系统。其中,该系统包括:第一CPU,用于向第一FPGA发送轨道交通数据的第一表决帧;第一FPGA,与第一CPU和第二FPGA连接,用于接收来自第一CPU的第一表决帧和来自第二CPU的第二表决帧,根据第一表决帧和第二表决帧生成第一表决结果;第二CPU,与第二FPGA连接,用于向第二FPGA发送轨道交通数据的第二表决帧;第二FPGA,与第二CPU和第一FPGA连接,用于接收来自第一CPU的第一表决帧和来自第二CPU的第二表决帧,根据第一表决帧和第二表决帧生成第二表决结果。通过本发明,解决了相关技术中CPU表决效率低的技术问题,增强了列控系统响应时效和整体安全性。
