High-precision micro-sensor vehicle overload and warning device used for bridge monitoring

Abstract

The invention discloses a high-precision micro-sensor vehicle overload and warning device used for bridge monitoring. The device comprises a power supply, multiple stress sensors, multiple displacement sensors, a signal conditioning circuit module connected with the multiple stress sensors and the multiple displacement sensors, an A / D (analog to digital) converting circuit connected with the signal conditioning circuit module, a processor module connected with the A / D converting circuit and used for analyzing and processing signals output by the A / D converting circuit to detect whether vehicles are overloaded or not, a touch screen connected with the processor module, a data storage module and an alarm module used for overload alarming, wherein the multiple stress sensors and the multiple displacement sensors are pairwise arranged on bridge arrangement nodes, and the power supply comprises an AC / DC (alternating current to direct current) converter and a chargeable battery connected with the AC / DC converter. The high-precision micro-sensor vehicle overload and warning device used for bridge monitoring is simple in structure, reasonable in design, high in monitoring precision, high in interference resistance, convenient to mount, flexible to configure, capable of dynamically detecting vehicle overload conditions when a vehicle travels at high speed, effective in use and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of bridge health monitoring, in particular to a high-precision micro-sensor vehicle overload and warning device for bridge monitoring. 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 overload...

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
