Description
Technical field
The utility model relates to the heavy system of a kind of vehicle pass-through meter.
Background technology
At present, China's freeway toll station has generally used vehicle dynamic weighing system, and, axle type, the fetalism heavy with the gross weight of loading class vehicle, axle and the milimeter number that goes are confirmed the charge number; Administer places such as station, weigh station, mine at vehicle overload, the vehicle dynamic weighing system that also all has been widely used is to detect vehicle weight.In the use of vehicle dynamic weighing system, requirement needs the vehicle of weight metering charging in low speed and at the uniform velocity through heavy weighting platform, to reach heavy accuracy requirement; But in actual use; Occurred in a large number vehicle at a high speed, the situation of speed change through weighting platform, the precision of weighing results significantly reduces, the error that has surpasses 30%; Cause a large amount of dispute incidents, had a strong impact on and weighed and charge order.
This just need carry out the equipment of measurement of vehicle speed on the track; When the tire of each axletree of vehicle reaches weighting platform; The speed of measuring vehicle; And calculate the position of each axletree at vehicle, so that, reach the purpose of accurate measurements and calculations vehicle weight to because the weighting error that the speed of a motor vehicle or vehicle acceleration cause compensates.
Occurred the detection axletree in the market and reached weighting platform to following weighting platform speed, acceleration; And the equipment that carries out the correction of axletree weight according to accekeration, the technology of application is: with the two weighting platform measuring speeds and the acceleration that are arranged side by side, vehicle tyre reaches and sails down the time of each weighting platform; Remove the width of weighting platform; Promptly obtain two speed, two speed promptly obtain the acceleration of this wheel shaft divided by the time; Single weighting platform and wheel shaft recognizer are measured; With aforementioned the same, obtain a speed with single weighting platform, coming up and down from weighting platform has a fixing distance between the wheel shaft recognizer; Divided by the time of crossing this segment distance; Promptly obtain second speed, these two speed promptly obtain the acceleration of this wheel shaft divided by the time.
But all there is certain defective in these two kinds of measuring methods: vehicle speed measurement is realized with contact equipment such as weighting platform, wheel shaft recognizers, although used new material and new technology, but break down easily, and price is more expensive; Have only vehicle axles could measurement of vehicle speed when the checkout equipment, acceleration; And other part of vehicle can not be measured through out-of-date; The length of vehicle, the wheel shaft information such as position on vehicle can't accurately be calculated like this, the acceleration that calculates weighing results is proofreaied and correct brought very big error.
The utility model content
The utility model technical matters to be solved provides the heavy system of a kind of vehicle pass-through meter, accurately measure each axletree reach, sail down the weight scale platform instantaneous acceleration, the compensation of being convenient to vehicle weight is calculated, and makes vehicle accurately count weight.
For solving the problems of the technologies described above; The utility model provides a kind of vehicle pass-through meter heavy system; It is characterized in that comprising: the heavy system of meter comprises the heavy weighting platform of meter, weighing instrument, when each axletree wheel of vehicle reaches the heavy weighting platform of said meter; The axle that said weighing instrument is measured this axletree is heavy, and the time T of this axletree of real time record when reaching the heavy weighting platform of said meter
