The invention provides a train head and tail redundancy system and a control method, and the train head and tail redundancy system comprises a main operation unit which is used for generating a query command and a time calibration signal; the function unit is used for receiving a query command sent by the main operation unit in a target period and sending query information corresponding to the query command to the main operation unit; the slave operation unit is used for receiving the time calibration signal sent by the master operation unit according to the target period and calibrating the time of the slave operation unit according to the time calibration signal; and the slave operation unit is used for sending a query command to the function unit in a target period under the condition that the master operation unit fails, and receiving query information sent by the function unit. According to the system, train data can be normally collected when the main operation system breaks down, clocks of the two operation systems are kept consistent, and continuous information receiving and transmitting of the hot standby redundant system are achieved.

    本发明提供一种列车首尾冗余系统及控制方法,该列车首尾冗余系统包括:主运算单元,用于生成查询命令和时间校准信号;功能单元,功能单元用于接收主运算单元以目标周期发送的查询命令,并向主运算单元发送查询命令对应的查询信息;从运算单元,从运算单元用于接收主运算单元以目标周期发送的时间校准信号,并根据时间校准信号校准自身时间;从运算单元用于在主运算单元发生故障的情况下,以目标周期向功能单元发送查询命令,并接收功能单元发送的查询信息。本发明所述系统能够在主运算系统发生故障时正常采集列车数据,并将两个运算系统的时钟保持一致,实现了热备冗余系统收发信息的连续。
