Problems solved by technology

If the client monitors a large number of terminals, each time the background server responds to the latest location data request from the client, the amount of terminal location data that needs to be sent back is very large, which will inevitably cause huge pressure on the server network and greatly limit the availability of the system. Number of simultaneous online users supported

Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Aiming at the WebGIS system, the present invention proposes a technology for grid management and incremental update of mobile terminal location data, to realize efficient update and real-time monitoring of a large number of mobile terminal locations, so as to effectively reduce data transmission between the client and the location server To ensure that a large number of client users browse multiple mobile terminals online at the same time.

[0045]In the WebGIS system, the real-time monitoring of the mobile terminal is achieved through the client continuously (with a fixed time interval, periodically) requesting the latest location data of the monitored mobile termi...

Abstract

The invention discloses a mobile terminal location data caching and real-time updating system and a mobile terminal location data caching and real-time updating method. A server real-time location service saves and manages the latest location data of all mobile terminals by taking a grid container as a unit; a client caches terminal location data obtained from a background server also by taking the grid container as the unit, and attaches the latest updating timestamps to each grid container respectively; and the client transmits a request to a location server to acquire terminal location updating data in each grid in a currently displayed boundary to realize the incremental updating of the terminal location data cached by the client by taking the grid as the unit. By the terminal-location-data-grid-based management and incremental updating technology, the real-time updating of mobile terminal locations in the display range of a map is ensured, data traffic between the client and the location server is effectively reduced, and the needs of a plurality of client users in the simultaneous online browsing of a plurality of mobile terminals are satisfied.

Description

technical field [0001] The invention relates to the field of satellite positioning and navigation, in particular to a system and method for caching and real-time updating of mobile terminal position data of a client in a WebGIS system. Background technique [0002] In the field of satellite positioning and navigation, a large number of mobile terminals need to be monitored in real time, such as ship position monitoring systems at sea or vehicle monitoring systems on land. The location monitoring system needs to keep the real-time update and display of the location data of the mobile terminal on the client side of the WebGIS (WebGIS: Internet-based network geographic information system) platform. [0003] The existing mainstream WebGIS systems are all based on the B / S (Brower / Server, browser / server) architecture, relying on the client browser to achieve cross-platform support for various client environments. The client is based on Web script technologies such as JavaScript o...
