Real-time on-line monitoring system for overloaded truck passing bridge

Abstract

The invention discloses a real-time on-line monitoring system for an overloaded truck passing a bridge. The real-time on-line monitoring system includes an RFID card, a management computer, a plurality of pressure sensors, a speed bump, an RFID card reader, a plurality of monitoring cameras, and an overload controller. The overload controller includes an ARM microcontroller module, a power supply module, a crystal oscillation circuit module, a reset circuit module, an SD card data storage circuit module, an RS-485 communication circuit module, a touch type liquid crystal display screen, an Ethernet communication circuit module, a power switch, a multipath simulation switch, a clock circuit module, a signal conditioning circuit module, and a voice prompt circuit module. The real-time on-line monitoring system has the advantages of simple structure, reasonable design, convenient use and operation, high vehicle overload detection accuracy, complete function, high working stability and reliability, high practicability, and easy popularization and use.

Description

technical field [0001] The invention belongs to the technical field of monitoring overloaded vehicles, and in particular relates to a real-time on-line monitoring system for overloaded trucks passing through 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 abili...

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
