Method, device and system for implementing position tracking

Abstract

The invention provides a position tracking implementation method, a device and a system, belonging to the technical field of a computer. The method for implementing the position tracking comprises the following steps that: a client side sends a position tracking service request for a navigation positioning system terminal to a first position tracking implementation device; after receiving the position tracking service request, the first position tracking implementation device returns coordinate data and map images to the client side; and the client side receives the coordinate data and the map images and integrates the coordinate data and the map images, generates and displays the position information of the navigation positioning system terminal in a map. In the technical scheme provided by the invention, the network bandwidth can be saved and the overhead of a remote server can be reduced. The invention also provides a multi-URL (Uniform Resource Locator) selective connection and processing mechanism; and after the response of the local position tracking implementation device is not obtained, the client side can send the position tracking service request to the remote position tracking implementation device, so that the fault-tolerant capability of the position tracking implementation system can be enhanced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and system for realizing position tracking. Background technique [0002] GPS (Global Positioning System) is a satellite navigation and positioning system established by the United States. With this system, users can achieve all-weather, continuous, real-time three-dimensional navigation and positioning and speed measurement around the world. GPS was originally established to provide precise positioning for the military, and has gradually been used in commercial and civilian fields, such as survey and mapping, aviation, navigation, vehicle tracking systems, mobile computers and cellular phone platforms. In recent years, GPS has been more and more widely used in our country, playing an irreplaceable role in exploration, surveying, aviation, navigation, emergency rescue, electric power, water conservancy construction, etc., greatly improving work efficien...

Problems solved by technology

[0006] In the traditional GIS architecture, as the business continues to expand, the number of clients continues to increase, because all client requests must centrally access the Web server, and the Web server has limited load capacity, resulting in system instability, slow response, and failure to operate On the other hand, the amount of map image data generated by the GIS platform is relatively large. If the map data is transmitted through the Internet network, it is not suitable for clients with too small network bandwidth, and there is also a phenomenon of wasting bandwidth resources. Although many systems now The design has adopted map slice technology (MapTile), which is to divide a map image into N small pictures, and then return the divided small pictures to the client part to display the map image one by one, thereby enhancing the effect of user experience, but this way It has never been able to fundamentally solve the problem of excessive network transmission traffic
