A method for automatically obtaining operation diagram files compatible with single-machine and dual-machine operation scenarios

Abstract

The present invention relates to a method for automatically acquiring operation diagram files compatible with single-machine and dual-machine operation scenarios, the method comprising: S 1 , read the configuration file; S 2 , if it is a stand-alone acquisition mode, then switch to S 3 , if it is a dual-machine acquisition mode, then go to S 4 ;S 3 , by periodically querying the list of running graph files under the line-side front-end server, and calculating the date and file name of the latest running graph file; If it changes, set the change flag; S 4 , By periodically going to the dual-computer front-end computer on the line side to query the file list, and calculate the latest file date and file name respectively, then compare the latest files of the dual-computer and remotely download the running diagram file to the local, and then obtain the same as the last processing. The latest file timestamp is checked against the file name, and if it changes, the change flag is set, etc. Compared with the prior art, the present invention has advantages such as being more flexible.

Description

technical field [0001] The invention relates to a rail traffic signal system, in particular to an automatic acquisition method for operation diagram files compatible with single-machine and double-machine operation scenarios. Background technique [0002] In recent years, urban rail transit in my country has developed rapidly, and the development of rail transit is of profound significance for improving the efficiency of urban public transport, optimizing urban spatial layout and improving urban land use efficiency. In order to understand the operation of each line in real time, cities with multiple subway lines, such as Beijing and Shanghai, are equipped with a comprehensive road network command system for unified management, dispatch and command of the operation of each subway line in the city. [0003] In the comprehensive command system of the road network, it is necessary to check and formulate the weekly operation demand according to the operation plan of the day, so a...

Problems solved by technology

[0004] At present, the existing solution is to update and synchronize the plan of the day and the actual plan in real time through network messages. However, this solution is a one-to-one model. When more systems need to use the operation chart data, more interfaces need to be expanded. Indirectly increase the maintenance cost of the system; and during the peak hours of driving, network interruption may also cause some operating data to be lost, so the data integrity may be insufficient
