A dynamic truck scale data processing method
By analyzing pressure waveforms, speed, and wheelbase information, and combining adaptive optimization and adjacent axle consistency verification, the dynamic truck scale accurately identifies whether the suspended axle is carrying weight, solving the problem of misjudgment of the suspended axle and improving the accuracy and fairness of over-limit judgment.

AI Technical Summary
Dynamic truck scales have a problem of misjudging whether the suspended axles of multi-axle trucks are actually bearing weight, especially the misjudgment of the number of axles due to changes in the state of the suspended axles, which affects the accuracy of the determination of overload and oversize.
By analyzing the pressure waveform, speed, and wheelbase information when a vehicle passes by, the key morphological features of each axle are extracted. An adaptive optimization strategy is used to determine whether the axle is actually bearing the weight. Combined with the consistency check of adjacent axles, the validity score is calculated and the axles that are actually bearing the weight are selected.
It achieves accurate identification of the suspended axle, avoids misjudgment of overload due to misjudgment of the number of axles, and improves the accuracy and fairness of dynamic truck scales in the enforcement of overload control at highway entrances and in non-site enforcement scenarios on national and provincial highways.
