Sažetak

Regularly detecting the wheel weight of EMU (Electric Multiple Units) is of great significance for maintaining the safety of railway transportation. The existing wheel weighing instruments are mostly the rail-broken type, which is easy to cause safety risks in long-term use. A rail-continues wheel weighing meter is introduced to solve the problem. The rail-continues wheel weight meter introduces a composite sensor structure, using BP neural network to search the optimal sensor factors and introduces a parameter to eliminate the interference of the EMU driving speed. To process the output of the BP neural network, a symmetric moving average filtering algorithm is proposed. The experimental results show that the wheel weighing meter introduced in this paper has high precision and stability. The weighing error of the continuous rail wheel weighing meter is 0.24%.
