High-precision micro sensor vehicle overload and warning device

Abstract

The invention discloses a high-precision micro sensor vehicle overload and warning device, which comprises a sensor group consisting of a plurality of pressure sensors arranged around a chassis of a monitored truck, a data acquisition module, a parameter setting unit for setting an overload alarm threshold value and a sampling time interval, a data processing module for analyzing and processing the information acquired by the sensor group and synchronously judging whether the monitored truck in the current state is in an overload state, a display module for synchronously displaying the current load weight and the rest loadable cargo quantity of the monitored truck according to the analyzing and processing result of the data processing module, an overload alarm module and a power supply management module. The device is reasonable in design, convenient to install and maintain, low in power consumption, convenient to arrange, easy and convenient to operate and reliable in performance, and can be used for detecting the actual cargo load of a vehicle in a dynamic or static state in real time, analyzing and judging the actual load according to the detection result and the preset threshold value and automatically giving a vehicle overload alarm.

Description

technical field [0001] The invention belongs to the technical field of vehicle overload monitoring, in particular to a high-precision micro-sensor vehicle overload and warning device. Background technique [0002] With the development of my country's economy and transportation, the phenomenon of overweight vehicles is becoming more and more serious. Overloading causes damage to road bridges and other facilities, thereby deteriorating road service levels and driving safety conditions, 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 vehicles, it is easy to cause traffic accidents. In some areas, traffic accidents related to vehicle overloading have accounted for about 20% of the total number of traffic accidents. Loaded engines that exceed the calibrated load of the car are always working at low speed a...

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, truck drivers can only estimate the load capacity of each cargo based on experience when transporting goods, which can easily cause vehicle overload inadvertently.

Frequent overloading for a long time will cause damage to the vehicle

Since long-distance trucks are often driven outside, once a breakdown occurs and the vehicle cannot work, maintenance is very inconvenient
