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. Howeve

Embodiment Construction

[0012] like figure 1 As shown, the entire system of the present invention is composed of a weighing platform, an information collection system (including a data center processor, a signal processor, and an axle identifier), an infrared grating vehicle separator, and the like. The shaft-coupled road automatic scale has a weighing platform 1 installed on the road surface 3. On the weighing platform 1, a vehicle entering the weighing platform is equipped with a grating vehicle separator 4 and an identifier 2 for identifying the upper scale axis; An identifier 2 for identifying the lower scale shaft is installed at one end of the vehicle on the heavy platform 1 when it is driven out of the weighing platform. The identifier 2 and the grating vehicle separator 4 are all connected to the computer in the toll booth 6 through the control cabinet 5 .

[0013] When the vehicle passes the weighing platform, the sensor signal is input to the weighing display controller, and the weighing di...

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...
