Problems solved by technology

[0003] Why are the current bridges suffering from natural disasters, man-made damage, vehicle overloading and other reasons, resulting in bridge damage accidents will cause many serious consequences
The reason is that the previous bridge design did not have an active early warning system, so it was only after an accident that the peripheral alarm was passively issued. The current bridge construction, when encountering earthquakes, mudslides, man-made and vehicle overload damage, the bridge breaks, and the difficult to fix right away

Abstract

A device for security monitoring of bridges by communication optical cables comprises optical cables and intermediate connectors and allows the communication optical cables to be mounted on lateral sides of bridges. The device is characterized in that the communication optical cable includes a main optical cable and an emergency optical cable with extending function, wherein the main optical cable is mounted on a set bridge body, the emergency optical cable and the main optical cable are mounted in parallel or are spaced from each other to be fixed on the set bridge body, the reserved length of the emergency optical cable is larger than that of the main optical cable, and the emergency optical cable is connected with the intermediate connectors and cameras. The device can realize precise-positioning alarm, has the advantages of safety, reliability, economical effect and practicability and convenience in maintenance, can guarantee monitoring of key portions of bridges, and gains time for handling accidents in case of accidents.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a communication optical cable for protecting the safety of bridges. Background technique [0002] With the rapid development of social economy, bridges have become the most important political, economic, and national defense arteries. The construction of bridges has become like the blood vessels and nerves in the human body. They are always responsible for our national defense construction and road traffic. To provide convenient services for traffic travel, these bridges are so important that once the bridges are interrupted, the people's lives and economic losses it will bring are immeasurable, especially our high-speed railways and highway bridges have been constructed according to regulations However, due to irresistible natural disasters, earthquakes, floods, and mudslides inevitably occur, and many bridges suffer from their own quality problems and overloaded vehicles ...
