A whole-vehicle measurement method for a full-table dynamic rail scale

Abstract

The invention discloses a whole vehicle metering method of a full-table dynamic rail weighbridge. The whole vehicle metering method comprises the processes of (1), collecting AD (Authenticated Dictionary) value data; (2), judging excessive balance of the vehicle; (3), judging a vehicle type; (4), judging a vehicle walking direction; (5), judging a vehicle walking speed; and (6) weighing the vehicle. A method with combination of an optimization algorithm and an average algorithm is used for processing data, so that the method is a core part of a vehicle identifying software algorithm of a full-table whole vehicle metering dynamic rail weighbridge; and the method comprises the steps of judging and calculating according to a synthetic waveform, finding a weight calculating section and calculating the weight. The whole vehicle metering method is capable of judging the running state of the vehicle on the rail weighbridge in real time and judging the information comprising the walking direction, the speed and the type of the vehicle.

Description

technical field [0001] The invention relates to a weighing method of a dynamic rail scale, in particular to a vehicle measuring method of a full platform dynamic rail scale. Background technique [0002] There is a clear difference between the dynamic track scale for full-table vehicle measurement and the conventional track scale for axle measurement and bogie measurement. The full-table vehicle measurement track scale has no obvious empty scale period, so it is difficult to use the original track scale algorithm to identify and measure vehicles. Calculation of weight. At the same time, due to the influence of the natural frequency of the train and the natural frequency of the weighing platform, there is a large amplitude of low-frequency periodic interference, which means that the useful signal collected while filtering out the low-frequency periodic interference is prone to distortion. In addition, the real-time requirements of the rail scale measurement program are stron...

[0002] There is a clear difference between the dynamic track scale for full-table vehicle measurement and the conventional track scale for axle measurement and bogie measurement. The full-table vehicle measurement track scale has no obvious empty scale period, so it is difficult to use the original track scale algorithm to identify and measure vehicles. Calculation of weight

At the same time, due to the influence of the natural frequency of the train and the natural frequency of the weighing platform, there is a large-amplitude low-frequency periodic interference, which means that the useful signal collected while filtering out the low-frequency periodic interference is prone to distortion

In addition, the real-time requirements of the rail scale measurement program are strong. After passing a car, the weight of the car must be calculated before the next car is weighed. Therefore, the filtering algorithm is particularly important, but it should not be too complicated.
