基于钢轨的应急通信系统设计

Design of rail-based emergency communication system

针对煤矿、在建隧道坍塌后通信中断、内外失联的问题,设计了基于钢轨的应急通信系统。该系统采用单片机控制产生振动信号,通过未彻底损坏的钢轨传输信号,并采用振动传感器拾取信号,最终实现应急通信。实验结果表明,该系统可以有效地实现信息的传递,能够达到灾后救援应急通信的目的。

In view of problem of communication interruption and contact lost after coal mine and tunnel under construction collapsed, rail-based emergency communication system was designed. The system uses MCU to control generation of vibration signals, transmits the signal through rail which is not completely damaged, and picks up the signal using vibration sensors, and ultimately realizes emergency communication. The experimental results show that the system can effectively achieve information transmission to realize the purpose of emergency communication for rescue after disaster.
