Security early-warning prompting system for bridges

Abstract

The invention relates to the technical field of security detection early warning for road traffic bridges, in particular to a security early-warning prompting system for bridges, which comprises a power supply module, an alarm circuit module and a voice, sound and light alarm device, wherein the power supply module consists of a storage battery module and a solar generating set; the anode output end and cathode output end of the solar generating set are connected with the anode input end and cathode input end of the storage battery module; the output end of the storage battery module is connected with a direct-current / direct-current (DC / DC) voltage conversion module; the output end of the DC / DC voltage conversion module is connected with an induction line open circuit comparison circuit and the alarm circuit module respectively; and the alarm circuit module is connected with the voice, sound and light alarm device. In the security early-warning prompting system, the induction line open circuit comparison circuit is adopted, so the early-warning prompting function of collapse accidents of the bridges can be better realized, and the sound and light alarm prompting function during bridge collapse can be realized. The system has a simple structure, and is stable and reliable and convenient to expand.

Description

Technical field: [0001] The invention relates to the technical field of road traffic bridge safety detection and early warning, in particular to a bridge safety early warning and prompt system. Background technique: [0002] In recent years, with the development of road traffic in our country, especially the rapid development of railway traffic, bridge engineering technology has also developed by leaps and bounds. With the further improvement of my country's major transportation networks, the traffic problems in remote areas and areas with complex geographical environments have been gradually overcome, and the construction of bridges has played an important role in it. The development of bridge engineering technology has made the structure of bridges more concise and beautiful, the span of bridges has been increasing, and the number of bridges with extra long spans has increased year by year. As an important part of national infrastructure, bridges play an increasingly impo...

Problems solved by technology

However, the detection of the bridge use process in the existing technology stays at static data collection analysis and dynamic evaluation, and its technical implementation is limited by geographical location, especially for bridge collapse accidents caused by sudden natural disasters in mountainous areas, effective monitoring and early warning cannot be implemented In this way, when bridges in remote areas suddenly collapse, they cannot warn the vehicles in time, and it is easy to cause the loss of people and property caused by the weather.
