客车火警信号装置民主德国研制的客车火警信号装置山火警信号台和与其连接的热敏元件及声光信号源——灯、铃、警报器组成。当发生火险时,热敏元件的信号传到火警台,再沿反馈线路将脉冲传到供电装置的控制与调节部件。这种部件将车上主要用电设备——照明、采暖、空调等与蓄电池断开。辅助用电设备部分在足够可靠接收火险信号的时间里与蓄电池是接通的。还有一个方案是火警信号装置与辅助电池接通,必要时辅助电池可代替主电池,从而大大提高该装置的可靠性。监测列车分离的压力传感器系统波兰铁路用制动主管的空气压力传感器系统来监测列车满长,而且采用若干不同的传感器型式。例如,在主管上接入一个带活塞的小风缸。当列车分离时,即主管中的压力降低,活塞移动,活塞杆接通声信号电路中的发生
Passenger fire alarm device developed in Germany Democratic Republic of Germany passenger fire alarm device mountain fire alarm signal Taiwan and connected to the thermal components and sound and light signal source - lights, bells, sirens composition. In the event of a fire hazard, the signal from the thermal element is transmitted to the fire alarm station and the pulse is transmitted along the feedback line to the control and regulating element of the power supply unit. Such components will be the main car electrical equipment - lighting, heating, air conditioning and battery disconnect. Auxiliary electrical equipment part of the reliable enough to receive fire danger signal with the battery is connected. A further solution is that the fire alarm signaling device is connected to the auxiliary battery and, if necessary, the auxiliary battery can replace the main battery, which greatly increases the reliability of the device. Pressure sensor system to monitor train separation The Polish railway uses brake master air pressure sensor systems to monitor the full train length and uses several different sensor types. For example, access to a small cylinder with a piston on the supervisor. When the train is disengaged, the pressure in the master decreases, the piston moves, and the piston rod engages in the acoustic signal circuit
