Description

TECHNICAL FIELD

[0001] The present application relates to the field of train route selection in multiple line areas, and particularly relates to a method for implementing a remote preset train route system. BACKGROUND

[0002] A railway line is an important basis for train operation. A train in operation must have only one determined operation line. However, a large railway line will inevitably have a route line, especially when a train crosses multiple provinces and runs a long distance, multiple route lines will be encountered. However, there is currently no efficient and safe route selection scheme. Only when the train travels to multiple route line areas, the train CIR device is manually operated by the driver to select the front operation line. This not only increases the additional operation of the driver and affects the train driving, but also may cause the driver to make a mistake in selecting the operation line. Once the operation line is selected incorrectly, it will affect the communication between the train driver and the station attendant and the data transmission of the train CIR device to the ground CTC device, causing the train to be temporarily parked, the train to be unable to run on time, the subsequent train to be delayed, and other serious problems. Therefore, it is urgent to develop a system that can automatically select a route to reduce driver operation and avoid affecting the safe operation of the train due to the driver's mistake in selecting the route line, and to realize the intelligentization and automation of route selection. SUMMARY

The train CIR device automatically selects the route line according to the route data file. When the route data file cannot determine the selection of the front route line, the driver manually selects the route line and generates new train number data through machine learning of the train CIR device to add to the preset route data file, so as to ensure that the train automatically selects the route when it runs to this area again.

[0004] The technical scheme adopted by the present application is: a method for implementing a remote preset train route system, the remote preset train route system is composed of a train CIR device, a ground server and a route data file preset in the train CIR device, and the implementation method is: the ground server realizes the editing, generation and transmission of the preset route data file, the ground server edits the preset route data file through a visual UI, saves it to the ground server, transmits the preset route data file to the train CIR device through a UDP protocol custom data format, and the preset route data file determines the automatic route selection.
