煤炭光纤呼救探测系统
产品简介
      本公司自主研发成功的煤炭光纤呼救探测系统是基于光纤传感技术的井下呼救装置,实现了井下遇险人员的紧急呼叫和传感探测,彻底实现了无电本安问题,属国内首创。该系统还可用于检测和监听煤矿井下煤层的音频信号,为预测预防煤矿井下采掘工作面的冒顶或煤与瓦斯突出提供辅助的监测信号。另外,当在较深煤层开采时,煤炭光纤呼救系统可以检测煤矿围岩的冲击地压发出的地音信号。
煤炭光纤呼救探测系统技术优势:
      ◇无需电源、本质安全;
      ◇防水、抗破坏能力强;
      ◇传输、传感双重功能;
      ◇可实现多个串接;
      ◇可实现远程监控;
      ◇应急语音通信功能。
