Being the bridge passing vehicle monitoring system and the bridge passing vehicle monitoring system in order to measure

摘要

PROBLEM TO BE SOLVED: To provide a bridge passage vehicle monitoring system for specifying inter-axial distance, vehicle speed, a vehicle model, and axle weight even by one distortion meter.;SOLUTION: One distortion meter 104 is arranged for every measurement position. The data of the inter-axial distance of a largely scaled vehicle are registered in an inter-axial distance database 32, and a reference axle weight distortion waveform 33 of one ton is stored. Then, the passage timing of an axle is detected from the distortion waveform measured by the distortion meter 104, and the inter-axial rate of the vehicle is calculated. Then, the inter-axial rate calculated from the passage timing is compared with the inter-axial rate calculated from the inter-axial distance registered in an inter-axial distance database 32, and the inter-axial distance, vehicle speed and vehicle model of the vehicle are specified. Also, the distortion waveform is generated by arranging the reference axle weight distortion waveform on a time axis according to the passage timing of the vehicle, and the reference axle weight distortion waveform is compared with the actually measured distortion waveform for one vehicle, and the axle weight of each axis is calculated.;COPYRIGHT: (C)2010,JPO&INPIT
