Aiming at the problems of high packet loss rate, large scheduling error and long scheduling delay in the railway wireless train communication network scheduling. Therefore, a GA-BP-based scheduling algorithm for railway wireless train communication network is proposed. Firstly, the structure characteristics of railway wireless train communication network are analysed. Then, complete the determination of dispatching technical parameters such as line impedance value, reflection coefficient, impedance value during line signal transmission, communication period, etc. Finally, the GA-BP scheduling model is constructed by combining the genetic algorithm and BP neural network algorithm, and the fitness function is introduced to modify the scheduling results to realise the scheduling algorithm design. The test results show that the packet loss rate in the proposed method is low, and the scheduling error is small. |
