The invention provides an intelligent door of a locomotive. The intelligent door comprises a door, a display alarm box and an electromagnetic lock arranged on the door, the display alarm box comprisesa control host and a display slave, the control host comprises a microprocessor minimum system, a signal acquisition module and an external driving circuit, the external driving circuit controls theon-off of the power supply of the electromagnetic lock, and the signal acquisition module is connected with a speed sensor arranged on a main shaft of the locomotive and a position sensor arranged ina lock hole of the electromagnetic lock. When the locomotive speed exceeds a safety threshold value, the electromagnetic lock is powered on to achieve locking of the door, meanwhile, whether the dooris normally closed or not is judged by detecting whether a spring bolt stretches out in place or not, the display slave communicates with the control host, current vehicle speed information, door state and fault conditions are fed back on the display screen in real time, and the display alarm boxes communicating with one another are arranged in driver's rooms at the two ends of the locomotive. Theintelligent door is high in intelligent degree, can guarantee the safety of drivers and passengers, and achieves the synchronization of the opening and closing state information of doors at two endsof the locomotive.
本发明提供一种机车智能门,包括车门、显示报警盒以及设置在车门上的电磁锁,显示报警盒包括控制主机和显示从机,控制主机包括微处理器最小系统、信号采集模块和对外驱动电路,通过对外驱动电路控制电磁锁的电源通断,信号采集模块与设置在机车大轴上的速度传感器以及设置在电磁锁锁孔内的位置传感器连接,当机车速度超过安全阈值时,电磁锁接通电源实现车门锁死,同时通过检测锁舌是否伸出到位判断车门是否正常关闭,显示从机与控制主机进行通信,并在显示屏上实时反馈当前的车速信息、车门状态以及故障情况,在机车两端的司机室内设有相互通信的显示报警盒。本发明智能化程度高,可确保司乘人员安全并实现机车两端车门的开闭状态信息同步。
