采用全光纤系统对高速公路隧道内机电设备进行监测,能够有效降低公路隧道机电工程监控设备的复杂程度。利用光纤光栅传感器对隧道机电设备的多种状态进行综合监测,能够实时了解机电设备的健康状态,为公路隧道的安全运营提供保障,并且具有电绝缘、安装简便、反应灵敏、实时高效的优点。

With the rapid development of highway in our country, highway tun-nel electromechanical equipment monitoring and management is increasingly important. Therefore a concise and effective monitoring method is needed. In this article, full optical fiber system is applied to monitor tunnel mechanical and electrical equipment. The complexity of the highway tunnel electro-mechanical engineering monitoring system could be effectively reduced. Fiber Bragg Grating sensor technology is applied to monitor multiple states of tunnel electromechanical equipment, and to know the health status of electromechanical equipment in real time for the safety of highway tunnel opera-tion. This method has advantage of electric insulation, convenient setting, and rapid response, real time and efficient.
