Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] like figure 1 As shown, a method for offline map train track display and playback, the method includes the following steps:

[0036] Step 1, the satellite positioning module on the train vehicle produces information that needs to be recorded, such as latitude and longitude, time, etc., and the speed sensor provides speed information, which is transmitted to the data acquisition module;

[0037] Step 2, the data acquisition module time-sequentialize...

Abstract

The invention relates to an offline map train track display and playback method and device, and the method comprises the following steps: step 1, satellite positioning data generated by a satellite positioning module and speed information collected by a speed sensor are sent to a data collection module; step 2, a data acquisition module carries out time sequence processing on the acquired data andstores the data; step 3, a data format is analyzed; step 4, the analyzed data interacts with an offline map on the webpage and deviation is corrected; step 5, track drawing and information display are performed; and step 6, according to the log data file, the train running track within a certain period of time is selected to be replayed. Compared with the prior art, the method has the advantagesof saving the flow of the webpage loading map, shortening the loading time, being beneficial to reducing the operation cost and the like.

Description

technical field [0001] The invention relates to a control technology for train operation, in particular to a method and device for displaying and replaying an offline map train track. Background technique [0002] In the development of most of the existing Gis systems, some dedicated Gis development platforms are generally used to record train trajectories, such as ArcGis, GlobalMapper, SuperMap and other professional platforms, or some current mainstream maps such as Baidu, AutoNavi Open API, considering that the dedicated development platform needs to purchase paid permission services, the development cost is relatively high, the use of the API needs to apply for the corresponding key value access, the number of times and time of use are limited, and different devices need to apply for different key values , The equipment used is limited. In some places where the external network coverage is not good, there will be a problem of slow loading of the map. For the point positi...
