Field static vehicle weighing detecting method of dynamic road vehicle automatic weighing instrument

Abstract

The invention provides a field static vehicle weighing detecting method of a dynamic road vehicle automatic weighing instrument. A technical scheme of the invention comprises the following steps: the dynamic road vehicle automatic weighing instrument is set in a dynamic weighing mode; each wheel axle of a reference vehicle passes a bearer of the dynamic road vehicle automatic weighing instrument in turn; each wheel axle stops while running to the centre of the bearer; the wheel axles are dynamically weighed one by one to obtain axle load values; and finally the axle load values can be accumulated to obtain total vehicle weight and indication error of the following different reference vehicles. The field static vehicle weighing detecting method of the dynamic road vehicle automatic weighing instrument, provided by the invention, has the advantages that influences on the reference vehicle from outside factors like speed variation (acceleration and deceleration), larger speed (too short sampling time), deviation from a central position (passing in a curve and passing from one side), levelness of road surfaces on two ends of the bearer and the like during passing the bearer are effectively reduced, a metering detecting precision is increased and an accuracy of the weighing instrument is assured on the premise of no change of the working mode of the dynamic road vehicle automatic weighting instrument and the structure of the reference vehicle.

Description

technical field [0001] The invention relates to a simulated static vehicle detection method for a dynamic road vehicle automatic scale under dynamic weighing conditions. The simulated static weighing is performed on each axle of a reference vehicle to obtain the axle load of the vehicle and the total weight of the whole vehicle. Background technique [0002] The on-site detection of the existing dynamic road vehicle automatic weighing instrument is completed in two parts: one is in the static working mode, using the standard weight to complete the detection of the static weighing performance index of the checked weighing instrument; the other is in the dynamic working mode, using the reference The vehicle travels through the weighing device to complete the detection of the dynamic weighing performance of the weighing device. [0003] Among them, the dynamic weighing detection is to complete the detection of the dynamic measurement performance index of the automatic weighing ...

AI Technical Summary

Problems solved by technology

Transverse slopes will cause unbalanced loading of the carrier, and longitudinal slopes will cause load transfer between the axles of the vehicle, reducing weighing accuracy

Moreover, this detection method cannot comprehensively simulate the driving state of the cargo vehicle, especially when the vehicle is queued in the lane and waits to pass, the common traffic method that the axle of the vehicle will stay on the carrier for a period of time is not included, so this method The accuracy of dynamic detection is low, and the range is not comprehensive enough

After error analysis, the detected data deviates greatly from the agreed true value of the vehicle weight, and it is easy to exceed the allowable range of error specified in the regulations, resulting in the failure of the check balancer
