Overload vehicle detection early warning system for bridges

Abstract

The invention discloses an overload vehicle detection early warning system for bridges. The system comprises a solar cell panel, a license plate recognizer, an overload vehicle recognizer, multiple stress sensors, multiple displacement sensors and a storage cell, wherein the overload vehicle recognizer comprises an ARM micro controller module, a voltage conversion circuit module, a crystal oscillator circuit module, a reset circuit module, an SD card data storage circuit module, a touch type liquid crystal display screen, a GPRS wireless communication module, a clock circuit module, a multi-path simulation switch, a first signal conditioning circuit module, a second signal conditioning circuit module, a charging control circuit and a sound-light alarm device, the charging control circuit is connected between the solar cell panel and the storage cell, and the sound-light alarm device is mounted on a street lamp pole. The overload vehicle detection early warning system has advantages of simple structure, reasonable design, convenient use and operation, high overload vehicle detection precision, high work stability and reliability, energy-saving and environmental-protection performance, strong practicality and convenient popularization and application.

Description

technical field [0001] The invention belongs to the technical field of overloaded vehicle monitoring, and in particular relates to an overloaded vehicle detection and early warning system for bridges. Background technique [0002] With the development of my country's transportation industry, people are paying more and more attention to the health maintenance of bridges. The health monitoring of long-span bridges to ensure the safety of bridge structures and realize early warning has become the primary issue, and the overweight phenomenon of vehicles has caused road bridges and other facilities The destruction of roads has deteriorated the level of road service and traffic safety conditions, resulting in expensive repair costs and even structural collapse, causing huge economic losses to the country. At the same time, traffic accidents caused by overloaded transportation are also increasing, threatening people's lives. Due to the reduction of the control ability of overloaded...

Problems solved by technology

On the traditional truck, since there is no built-in load detection device, the weighing of the truck is carried out when the truck is stationary after the cargo is loaded. This weighing method is the most accurate method, but this traditional weighing method The heavy method has its own shortcomings, the measurement efficiency is low, manual intervention is required, and it is impossible to dynamically monitor the axle load of the driving vehicle without stopping for 24 hours

Due to the above shortcomings, the maintenance of the health status of the bridge cannot be controlled in time
