Vehicle weighing state detection system and method

Abstract

The invention discloses a vehicle weighing state detection system, which comprises weight counting equipment, a weight counting charging system, a signal shunt, a front-end collecting module and a rear-end early warning module. The signal shunt collects analog signals from the weight counting equipment, and the analog signals are imaged in the signal shunt by an emitter follower to form two signals equal to the original signals in magnitude, wherein one way of the signals is returned to the weight counting charging system, and the other way of signal is returned to the front-end collecting module to be subjected to data analysis; the front-end collecting module conducts data analysis on each signal, and returns the calculation results to the rear-end early warning module; and the rear-endearly warning module can directly calculate an equipment failure module, sends out a reminding repairing signal, and automatically compensates the loss total weight to the system. An owner monitoringplatform is effectively combined, the failure position can be quickly determined, meanwhile, the weight counting result after data repair of damaged equipment is given, and owners are assisted in counting the loss weight.

Description

technical field [0001] The invention belongs to the field of weighing detection, and relates to a vehicle scale weighing state monitoring system and a detection method, in particular to the detection of a weighing sensor under a dynamic vehicle scale weighing platform on an expressway. Background technique [0002] At present, truck scales have been widely used in high-speed toll collection and high-speed pre-inspection. However, trucks on expressways are overloaded, overrun, weighed and skipped scales often make the load cell overwhelmed and fail. During the long-term use of the dynamic truck scale, there may be sensor failure problems. The failure of some sensors will not cause the entire weighing system to work abnormally, but it will seriously affect the weight of the toll. In order to reduce the risk of highway toll loss , it is necessary to accurately detect the fault sensor, and report the fault information to the maintenance personnel in time. However, the tradition...

Problems solved by technology

At present, the commonly used truck scale sensor configuration scheme in the industry is to incorporate multiple analog sensors into the junction box and output them as an analog signal to the weighing control system. Although this method can dynamically detect the weight on the weighing platform in real time, it cannot Detect the analog signal value of each load cell, that is, when a sensor fails, the faulty sensor cannot be located

The existing charging system does not have perfect sensors and weighing system status detection equipment for early warning, resulting in weight loss of the weighing system
