Embodiment Construction

[0032] First, the national railway network is organized according to the public works lines, and the high-density correspondence matrix between the mileage marks and GPS points of each line is obtained according to the following steps:

[0033] Step A, obtain a train LKJ monitoring record file or bullet train EOAS monitoring record file, do interpolation encryption processing as required, 5 to 8 kilometers mark recording points per second, preferably, 6 km mark recording points per second, and remove Duplicate data;

[0034] Step B, obtain the GPS sampling point file of the same train, do interpolation encryption processing as required, 5 to 8 GPS longitude and latitude record points per second, preferably, 6 GPS longitude and latitude record points per second, and remove duplicate data;

[0035] Step C, matching the monitoring record file and the GPS sampling point file of the same train according to the time to obtain the high-density line GPS latitude and longitude and the ...

Abstract

The invention discloses a method for positioning train lines. The method comprises the following steps of firstly organizing a railway network of the whole country according to public-work lines, and dividing main lines and branch lines according to the lines of operation sections so as to obtain a high-density correspondence lattice between kilometer posts and GPS points of the lines; using a route indicator as a trigger point, beginning to select all possible routes (branch lines) passing the points from the points passing the route indicator, matching all the selected possible routes (branch lines) with current GPS longitude and latitude, and obtaining the lines with the shortest distances so as to position practical lines through an error shielding mechanism; and besides, once the branch lines or the main lines are positioned, no longer matching the branch lines and the main lines, and only dynamically matching 100-150 points before and after current GPS points on a mobile terminal. According to the method for positioning the train lines disclosed by the invention, the main lines and the branch lines in the complex railway network can be positioned quickly, accurately and effectively, navigation prompt can be performed timely and accurately to trainmen, and the method has broad application prospects.

Description

technical field [0001] The invention relates to the field of railway train navigation, in particular to a method for locating train lines by GPS latitude and longitude. Background technique [0002] Due to the intricate network of railway lines, dozens of hundreds of main lines and branch lines are interlaced, and the operating mileage of railways is as high as hundreds of thousands of kilometers. At the same time, the mobile terminal equipment is limited by its computing power, and it is really difficult to calculate and locate the current main line and branch line kilometer marks through the current GPS latitude and longitude within tens of milliseconds. [0003] In the past few years, on average, many construction personnel or maintenance personnel along the railway line caused accidents because they failed to detect the train approaching in time. Railway locomotive managers need to know the specific location of running trains in order to manage. The traditional locatio...
