Coupling type automatic road scale

Abstract

A coupling type automatic road scale is characterized in that the scale is provided with a weighing platform installed on the road surface, and an optical grating vehicle separator and a recognizer for recognizing an upper scale shaft are installed at the end, for vehicles to enter, of the weighing platform; a recognizer for recognizing a lower scale shaft is installed at the end, for vehicles to pull out, of the weighing platform, and the recognizers and the optical grating vehicle separator are all connected to a computer in a toll booth through a control cabinet. The coupling type automatic road scale overcomes the defects that an existing truck scale is high in manufacturing cost, large in basic manufacturing work amount and long in construction period.

Description

technical field [0001] The invention relates to a metering device for weighing the weight of a vehicle based on the single-axis weight of the upper and lower weighing platforms, the number of axes and the weight of multiple axes staying on the weighing platform. The invention belongs to the technical field of truck scale manufacturing. Background technique [0002] At present, the most used weighing equipment in the high-speed kilometer toll is the axle load meter (the length of the scale body is about 0.8m) and the vehicle-type weighing equipment (the length of the scale body is about 18-24m). [0003] The axle load meter uses single-axis weighing, and then superimposes the weight of the whole vehicle, because when weighing each axis, the limitations of this equipment are relatively large: affected by the speed of the vehicle, the speed compensation when weighing each axis Washing cannot be accurately determined, so the weight error of the whole vehicle is large. In normal...

Problems solved by technology

[0003] The axle load meter uses single-axis weighing, and then superimposes the weight of the whole vehicle, because when weighing each axis, the limitations of this equipment are relatively large: affected by the speed of the vehicle, the speed compensation when weighing each axis Washing cannot be accurately determined, so the weight error of the whole vehicle is large

In normal use, the error is relatively large due to reasons such as jumping scales and flushing scales.

[0004] The emergence of vehicle-type weighing equipment makes up for the shortcomings of axle load meter weighing. Vehicle-type weighing is not affected by the external environment. However, due to the large length of the scale body, there are high manufacturing costs, large amount of basic manufacturing engineering, and construction problems. Disadvantages of long cycle

Especially when there is not enough distance to install the toll stations that have been built, the slope needs to be adjusted to change the layout of the square, which will result in a longer construction period and increased costs

[0005] The purpose of the present invention is to provide a coupling type road automatic scale to overcome the disadvantages of high manufacturing cost, large amount of foundation production and long construction period in the existing truck scale
