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...

Embodiment Construction

[0033] Such as figure 1 Shown, a kind of whole vehicle metering method of full platform dynamic track scale of the present invention, it comprises following process:

[0034] (1) Collect AD value data: collect the AD value data of the left weighing platform and the right weighing platform of the dynamic track scale at fixed time intervals through dual-channel data acquisition;

[0035] (2) Vehicle overweight judgment: If the AD value data of the left weighing platform or the right weighing platform is greater than the set threshold value, it is determined that the vehicle is on balance;

[0036] (3) Car model judgment: judge the model of the vehicle measured by SHS;

[0037] (4) Judging the direction of vehicle travel;

[0038] (5) Vehicle speed judgment;

[0039] (6) Vehicle Weight: Carry out vehicle weight calculation.

[0040] Further, the collection process of AD value data described in the above method comprises the following steps:

[0041] 11) Collect the analog da...
