Embodiment Construction

[0058] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0059] figure 1 It is a figure which shows one Embodiment of the axle load measuring system which is this invention.

[0060] In addition, in the following Figure 1 to Figure 10 In , the same symbols are attached to the same parts or corresponding parts.

[0061] 11 in the figure is a road (for example, expressway, etc.) on which ordinary cars or large cars pass, and 12 is a vehicle (for example, a truck as a large vehicle) passing on the road 11 .

[0062] 13 is an axle load measuring device for measuring the load on each axle of the vehicle 12 , that is, the axle load, and is installed on the roadside of the road 11 . The axle load measuring device 13 is connected to two axle load sensors 32a and 32b for detecting the axle load, and the axle load sensors 32a and 32b are composed of rod-shaped sensors utilizing piezoelectric effects such as crystals.

Abstract

The invention provides an axle load measuring system and a vehicle separation method. The weight of each vehicle can be measured without installing a dedicated device for vehicle separation. According to the detection output of the axle load sensors (32a, 32b), calculate the inter-axle distance between the axles of the vehicle (12), and determine whether the inter-axle distance is consistent with the inter-axle distance information in the pre-prepared vehicle data. Whether the inspection axle and the rear inspection axle are the axles of the same vehicle. When it is determined that the front inspection axle and the rear inspection axle are not the axles of the same vehicle, separate the axle load measurement results of the front inspection axle and the axle load measurement results of the rear inspection axle, according to the axle load before the separated front inspection axle The measurement results are used to calculate the total weight of each running vehicle.

Description

technical field [0001] The present invention relates to an axle load measurement system for measuring the axle load of passing vehicles using an axle load sensor provided on a road surface, and a vehicle separation method for separating vehicles one by one in the system. Background technique [0002] Against the background of the development of the logistics industry in recent years, transportation and distribution by large vehicles such as delivery trucks have increased, and with the increase of these large vehicles, there are a large number of vehicles that are overloaded to prioritize efficiency, that is, overweight vehicles. Such overweight vehicles cause damage to road surfaces, bridges, etc., and become factors that threaten road traffic safety. [0003] In order to preserve the road structure or prevent traffic hazards, in the "Vehicle Restriction Order" (Decree of July 17, Showa 36) based on Article 47, Item 1 No. 265) and "Ministry Order for Determining Vehicle Per...
