Embodiment 1

[0031] Such as figure 1 Shown is a schematic structural diagram of a train tracking state acquisition system provided by Embodiment 1 of the present invention. It should be pointed out that the system of the embodiment of the present invention is installed on the test train for use, and it can complete the collection and calculation of various data while the train is moving. The system includes a GPS receiving unit 110 , a decoding unit 120 , a recording unit 130 and a computing unit 140 , wherein the decoding unit 120 is connected to the GPS receiving unit 110 and the recording unit 130 respectively, and the computing unit 140 is connected to the recording unit 130 .

[0032] The GPS receiving unit 110 is used to receive the GPS real-time positioning package. The core of the embodiment of the present invention is to apply the GPS technology to automatically obtain the tracking state of the train. Parameters such as time information of each measurement point, and these parame...

Embodiment 2

[0039] Such as Figure 4 Shown is a schematic structural diagram of a train tracking state acquisition system provided by Embodiment 2 of the present invention. The system includes a GPS receiving unit 410, a decoding unit 420, a recording unit 430, a computing unit 440, a timing unit 450 and a measuring point marking unit 460, wherein the GPS receiving unit 410, the decoding unit 420 and the computing unit 440 are similar to those in the first embodiment , which will not be repeated here.

[0040] The timing unit 450 is connected with the GPS receiving unit 410 and the recording unit 430 respectively, and it is used for when the test train enters a block road section (such as a tunnel, etc.), when the GPS receiving unit 410 of this system cannot receive the GPS positioning packet, the current GPS time base Automatically start on the computer to ensure the continuity of time records in the database. Specifically, since the database not only has the latitude and longitude inf...

Embodiment 3

[0051] Such as Figure 8 Shown is a schematic flow chart of a method for obtaining a train tracking state provided by Embodiment 3 of the present invention, and the method includes the following steps:

[0052]S801: Receive the global positioning system GPS real-time positioning package. The core of the embodiment of the present invention is to apply GPS technology to automatically obtain the tracking state of the train. Parameters such as time information when measuring points, and these parameters can be obtained by GPS technology. The process of receiving the GPS real-time positioning packet belongs to the prior art, and will not be repeated here.

[0053] S802: Decode the GPS real-time positioning packet to obtain latitude and longitude information, GPS mileage information, GPS time information and train speed information.

[0054] S803: Determine whether the latitude and longitude information is the same as the latitude and longitude of the measuring point marked in the...

Abstract

The invention provides a method and system for acquiring the tracking status of a train. The method comprises the following steps of: receiving a real-time positioning pocket of a GPS (Global Positioning System); decoding the real-time positioning pocket of the GPS to acquire latitude and longitude information, GPS mileage information, GPS time information and train speed information; judging whether the latitude and longitude information is identical to the measuring point latitude and longitude calibrated in a database and recording the GPS mileage information, the GPS time information and the train speed information in the database file of the measuring point if the latitude and longitude information is identical to the measuring point latitude and longitude; and calculating the tracking status between trains according to the GPS mileage information, the GPS time information and the train speed information in the database file. The embodiment of invention has the advantages of highaccuracy, labor saving and multiple detection points.

Description

technical field [0001] The present invention relates to the field of data collection, in particular to a method and system for acquiring a train tracking state. Background technique [0002] During the trial operation of the train, various trial operation tests are required, such as: parameter test of the train operation diagram, fault simulation, emergency rescue drill, etc., to test the adaptability of the various systems in the train to the transportation organization under normal and abnormal conditions; Whether the running organization of the train can meet the operational requirements; test the emergency handling ability under the conditions of equipment failure and natural disasters, so as to provide a technical basis for formulating a scientific and reasonable train transportation organization plan. [0003] The above-mentioned train diagram parameter test is an important part of the test run test, and the train tracking interval test belongs to the core of the train...
