The invention discloses a driver vigilance reminding circuit and a driver vigilance reminding system. Through the power-on and power-off logic of the time-delay relay, the functions that the buzzer alarms after the duration time of releasing the vigilance button exceeds 2S, the train triggers emergency braking after the duration time of releasing the vigilance button exceeds 3S, and the buzzer alarms after the duration time of pressing the vigilance button for a long time by a driver exceeds 3S are achieved. Meanwhile, the buzzer alarms when keys are inserted into the cabs at the two ends to activate the train, and the driver operates the emergency braking bypass switch to bypass the train emergency braking function, so that the buzzer alarms; according to the design, the problem of failure of a vigilance alarm function when a network fault occurs is solved, the potential danger of no driver supervision of the train is comprehensively considered, and the train operation efficiency and the passenger riding comfort are improved.
本发明公开了一种司机警惕提醒电路及系统,在电路中设置3组延时继电器,通过延时继电器得失电逻辑实现松开警惕按钮持续时间超过2S蜂鸣器报警、松开警惕按钮持续时间超过3S后列车触发紧急制动、司机长按警惕按钮持续时间超过3S蜂鸣器报警功能,同时实现两端司机室均插钥匙激活列车时蜂鸣器报警、司机操作紧急制动旁路开关旁路列车紧急制动功能蜂鸣器报警功能;此发明设计解决了网络故障时警惕报警功能失效问题,同时全面考虑列车无司机监管潜在危险,提高列车运行效率及乘客乘坐舒适度。
