Abstract

The invention discloses a tunnel safety monitoring device based on an optical fiber sensor. The tunnel safety monitoring device comprises a shell, a fixing mechanism for fixing the monitoring device to a wall body is connected to a side wall of the shell, a main control module is arranged in the shell, a heat dissipation plate at the joint of the main control module is embedded in the shell, an S-shaped condensation chamber is arranged in the heat dissipation plate, a water storage chamber is formed in an inner wall of the shell, the water storage chamber is filled with cooling liquid, a wateroutlet end of the condensation chamber communicates with the water storage chamber, and a water pressing device for pressing the cooling liquid in the water storage chamber into the condensation chamber is arranged at a water inlet end of the condensation chamber. The tunnel safety monitoring device proposed by the invention solves the problems that the device occupies an excessive space, a largenumber of cables need to be paved, and an external power supply is needed, and the problems that the existing monitoring device is high in energy consumption, is susceptible to electromagnetic interference, ambient temperature and humidity, low in precision, long in cycle, low in data transmission efficiency, poor in stability and low in reliability.

Description

technical field [0001] The invention relates to the technical field of tunnel maintenance equipment, in particular to a tunnel safety monitoring device based on an optical fiber sensor. Background technique [0002] With the development of social economy, traffic has become more and more convenient. Tunnel construction has played an important role in the development of traffic. However, the health of tunnel projects needs to be continuously tested after construction, and its health is directly related to the masses. The safety situation of daily life, in order to repair the tunnel in the early stage of damage or fracture, it is necessary to design a device for real-time monitoring of tunnel health. [0003] The traditional way to achieve monitoring is based on wired sensor data collection, which makes it necessary to connect the monitoring center and tunnel detection points through cables, requiring the laying of a large number of cables, which is not only time-consuming, la...
