| Popis: | Objective With the increasing number of rail transit vehicles in operation, the maintenance workload for data is also increasing. The existing data landing methods have many drawbacks, necessitating research into new data transmission methods to reduce the failure rate of trains. Method By comparing Wi-Fi and 4G technologies, it is determined to utilize the both. Considering the need for network coverage on main lines and in depots, three channels are ultimately established to ensure data transmission under different conditions and locations. Meanwhile, to ensure the security of data transmission, several security measures are implemented to prevent channel attacks. Result & Conclusion Experimental results demonstrate that the proposed approach can effectively and reliably download data to ground servers. Moreover, in the event of a channel failure, the remaining channels can continue to operate, ensuring uninterrupted data transmission. |
