Processing device and method for E-map tile request queues

Abstract

The invention discloses an E-map tile request queue processing device and an E-map tile request queue processing method. The method includes: according to a received E-map interaction instruction, determining target-level tile requests to be downloaded and preloading-level tile requests; adding the target-level tile requests and the preloading-level tile requests to an E-map tile request queue, and processing prior to original tile requests in an original queue. The target-level tile requests t and the preloading-level tile requests are added to the E-map tile request queue, the requests newly added to the E-map tile request queue are processed prior to the original tile requests in the queue, the target-level tile requests and the preloading-level tile requests are processed prior, and chances of an E-map window being blank are slimmed.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to an electronic map tile request queue processing device and an electronic map tile request queue processing method. Background technique [0002] At present, the electronic map client needs to load the electronic map tiles when it receives an electronic map interaction instruction input by the user (such as an instruction to enlarge the map, an instruction to zoom out the map, an instruction to pan the map, etc.). The client needs to request the electronic map server to download the electronic map tiles. However, the existing electronic map technology lacks the management and maintenance technology for the tile request queue. For example, when using the existing electronic map client, if the user short If the electronic map interaction instructions are input multiple times within a certain period of time, the number of requests for downloading tiles will be large, and the ...

The client needs to request the electronic map server to download the electronic map tiles. However, the existing electronic map technology lacks the management and maintenance technology for the tile request queue. For example, when using the existing electronic map client, if the user short If the electronic map interaction instructions are input multiple times within a certain period of time, the number of requests for downloading tiles will be large, and the load on the network, client and server will be heavy, and some target level tiles will not be displayed in time, and there will be blanks in the electronic map window; network performance When it is not good, the blank space of the electronic map is more obvious
