Optical fiber vibration early warning system for pipe gallery
The invention relates to an optical fiber vibration early warning system for a pipe gallery. The optical fiber vibration early warning system comprises a management platform, two or more early warning subsystems, two or more video monitoring devices and an alarm. The management platform is connected with the early warning subsystem, the video monitoring device and the alarm. Each early warning subsystem comprises a sensing terminal device, a sensing initiator and an optical fiber vibration host; the sensing terminator is connected with the sensing initiator through a sensing optical cable, and the optical fiber vibration host is connected with the sensing initiator through a connecting optical cable. Abnormal conditions in the pipe gallery are monitored according to the optical fiber vibration principle, long-distance real-time seamless monitoring on the vibration condition of soil along the pipe gallery can be achieved, and accurate target positioning is conducted on a damage event through accurate vibration signal analysis; omnibearing and real-time online monitoring and real-time alarming of the underground comprehensive pipe gallery can be achieved, and the rapid response and safety prevention and control capacity of operation management of the urban underground comprehensive pipe gallery are greatly improved.
本发明涉及一种用于管廊的光纤振动预警系统，包括管理平台、2个或2个以上预警子系统、2个或2个以上视频监控设备、报警器；所述管理平台分别与预警子系统、视频监控设备、报警器连接；每个预警子系统包括传感终端器、传感起始器、光纤振动主机；所述传感终端器通过感应光缆与传感起始器连接，所述光纤振动主机通过连接光缆与传感起始器连接。本发明通过光纤振动原理实现对管廊内异常情况的监测，能够实现对管廊沿线的土壤振动情况进行长距离实时无缝监测，通过精确的振动信号分析，对破坏事件做出准确的目标定位；能够实现地下综合管廊的全方位、实时在线监测，实时报警，大大提高城市地下综合管廊运行管理的快速反应和安全防控能力。
