Problems solved by technology

However, the manual method has a large workload, low efficiency and high error rate
In addition, the database cannot be updated in real time after manual conversion processing, and it needs to be updated manually, which consumes a lot of manpower and material resources
With the increasing number of upgrades and transformations of railway lines, LKJ data updates will be more frequent, manual database conversion is difficult to meet the requirements, and there are safety risks in automatic control vehicles

Abstract

The present invention provides an automatic conversion method of a track line database which can be updated in real time. The method comprises that: a line database automatic conversion platform transmits an LKJ line data request to an LKJ host; the LKJ host receives the request from the line database automatic conversion platform, and transmits LKJ line data to the line database automatic conversion platform; the line database automatic conversion platform receives the LKJ line data transmitted by the LKJ host; the line database automatic conversion platform reads a pre-set LKJ line data conversion configuration file, wherein the LKJ line data conversion configuration file comprises a train running area index table and an area line parameter table; the line database automatic conversion platform converts the LKJ line data according to the train running area index table and the area line parameter table; and the line database automatic conversion platform carries out sorted storing on the converted train running area line data. According to the method and system provided by the present invention, the database conversion update efficiency is improved and the data error risk is reduced.

Description

technical field [0001] The invention relates to the technical field of train communication, in particular to a method and system for real-time updating of a rail line database. Background technique [0002] Energy conservation and environmental protection are the long-term strategic pillars for the sustainable development of the country and society. The key to energy conservation in the railway transportation industry lies in the reduction of locomotive energy consumption. Intelligent operation optimization control technology is an important way for locomotive energy conservation. Foreign advanced train intelligent control technology generally adopts digital track line database based on GPS information for control optimization calculation and adaptive control. For the current situation of railways in my country, the LKJ (train operation monitoring device) line data provides complete basic line information such as lines, signals, and stations. monitoring and security. Since ...
