Locomotive Number, Then Simultaneous Real-time Transmission System

In railway system,trains collect diversified data with the recording system for train operation monitor and recording device ,then transmit to microcomputers on the ground to manage and analyse through memory device at present.The means of data processing is delayed because the process is taken place after the locomotive returned Railway Branch Locomotive Depots.The data processing does not reflect the real-time train's operation status. To solve the above question, this project designs a real-time transmssion system for data of train operation.This thesis gives a real-time system based on train radio to transmit operation information .The system decribes the technology of Data/Voice compatible Radio Train Dispatch Communication System through Voice Compression/expansion to transmit voice and data synchronously.And through Railway Packet Switching Network the data can access the Railway Branch Locomotive Depots. The system includes the data-voice compatible train radio dispatching communication system and the ground's data transmission system.In the paper,we mainly designs interface circuit of train operation monitor and recording device,researchs Data/Voice compatible train dispatching radio communication subsystem and communication protocols,discusses data transmission on the ground,etc.The design of this system is advanced,the technology of application is mature and the foreground of application is fine.
