Problems solved by technology

The whole system design is feasible to a certain extent, but the biggest defect of the system is: 1. When manually inputting the value of "specified axle load mass", it can only rely on the management personnel's identification of the shape of the vehicle under test, and there are high misjudgments probability, and there will be a phenomenon of being at a loss for refitting vehicles
2. The value of "specified axle load quality" is manually input by the management personnel, which has not reached the automatic level of vehicle overload identification

Abstract

The invention relates to a vehicle overload automatic identification system, comprising a load transducer, a PC apparatus, a road port, a CCD cam, an image and data acquisition card. The output signal from load transducer, which is buried in advance in road paort, is lead out from a load transducer via preseted signal cable conductor, then a CCD cam gathers vehicle front and rear outline picture, while an image and data acquisition card pre-processes image signals and pressure sensing signals. The pressure load signals from a preseting signal cable conductor and image singals from picture video cable conductor of CCD cam are separately connected to analog signal ingate of image and data gathering cards and video signal ingate, while an image and data gathering card is connected to a PC apparatus via PCI bus.

Description

technical field [0001] The invention relates to a system used in the technical field of automobile detection, in particular to an automatic overload identification system for automobiles. Background technique [0002] In our country, the phenomenon of truck overloading and illegal refitting and loading is very serious, causing most roads and bridges to be in an overloaded state for a long time, which not only seriously affects the service life of roads and bridges, but also causes frequent traffic accidents during vehicle driving, especially in a certain Some highways are even more overwhelmed and dangerous. To completely avoid and stop the occurrence and existence of this kind of phenomenon, in addition to strengthening and perfecting the traffic legal system and establishing a scientific management system, it is very important to have a set of modern scientific and technological means to assist in solving it. [0003] According to literature search, Zhang Youliang, Yuan M...
