Bridge-vibration intelligent power supply system and method

Abstract

The invention discloses a bridge-vibration intelligent power supply system, which comprises an energy conversion device, an electric energy accumulation device and a power source management device, wherein the energy conversion device comprises a vibration transmission mechanism, a connecting rod, a crank and an engine; the vibration transmission mechanism transmits the vibration pressure of a bridge to a connecting rod firstly and then to the crank through the connecting rod; the crank is connected with an input shaft of the engine and used for driving the input shaft of the engine to rotateand generate electricity; the electric energy accumulation device comprises a rectification circuit, a conversion / process circuit I, a conversion / process circuit II, a super capacitor and a storage battery; the power source management device comprises an electric energy management controller and power source channels, a power source input terminal of the electric energy management controller is connected with a power source output terminal of an energy management device, and is connected with monitoring devices of bridges through a plurality of power source channels. The bridge-vibration intelligent power supply system has a compact structure, fully utilizes vibration pressure of the bridge when vehicles move on the bridge, and achieves the purposes of saving energy and electricity and ensuring the uninterrupted operation of the monitoring parts.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring, in particular to a system for realizing intelligent power supply of monitoring components by using bridge vibration, and also relates to an intelligent power supply method. Background technique [0002] Bridges are one of the important infrastructures of the country. With the rapid development of bridge construction, people pay more and more attention to bridge safety issues. As the service period continues, the bridge structure may deteriorate, and the increasing traffic volume and overloading may exceed the original design standards, thereby reducing the reliability of the bridge, and even causing bridge safety problems, leading to catastrophic disasters. ACCIDENT. The construction and maintenance of large bridges requires a lot of manpower, material and financial resources, lagging behind the comprehensive monitoring and evaluation methods of bridge construction and development, so ...

AI Technical Summary

Problems solved by technology

Nowadays, the components of bridge health monitoring are becoming more and more miniaturized and low-power consumption. It takes a waste of manpower, material resources and financial resources to pull in the mains power. Moreover, unreasonable wiring methods also affect the accuracy of data collection.
