Offline positioning method of electronic equipment, service equipment and system

Abstract

The embodiment of the invention relates to the technical field of positioning, and discloses an offline positioning method of electronic equipment, service equipment and a system, and the method comprises the steps: obtaining a positioning request, reported by user equipment, for first electronic equipment, wherein the positioning request at least comprises an identity identification of the firstelectronic equipment; querying position information corresponding to the identity identifier of the first electronic equipment from a database; pushing the position information to the user equipment;wherein the position information corresponding to the identity identifier of the first electronic equipment is the position information of the second electronic equipment reported by the second electronic equipment in advance and the distance between the second electronic equipment and the first electronic equipment and the relative angle between the second electronic equipment and the first electronic equipment are calculated. According to the embodiment of the invention, the offline positioning of the electronic equipment can be realized without downloading the off-line map packet, and the storage resource is not occupied.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to an offline positioning method for electronic equipment, service equipment and a system. Background technique [0002] At present, wearable devices appearing on the market all have offline positioning functions, and most of these wearable devices' offline positioning functions need to download a city's offline map package in advance, and then use the WiFi and GPS searched by the wearable devices. Information analysis, and finally realize offline positioning without network. [0003] However, in practice, it is found that because the downloaded offline map package needs to occupy a large storage resource location, it is easy to cause wearable devices with small storage resources to be unable to realize the above-mentioned offline positioning function, and the offline map package needs to be downloaded from the network frequently. Continuous updates will cause position...

[0003] However, in practice, it is found that because the downloaded offline map package needs to occupy a large storage resource location, it is easy to cause wearable devices with small storage resources to be unable to realize the above-mentioned offline positioning function, and the offline map package needs to be downloaded from the network frequently. Continuous updates will cause positioning errors on wearable devices due to untimely update of offline map packages
