Embodiment

[0033] The technical scheme of the present invention is illustrated in detail below.

[0034] The positioning data storage, conversion and query method in this example is based on the existing positioning data storage, conversion and query system. The system includes a positioning device, a server and a terminal device, and the server communicates with the positioning device and the terminal device respectively. The following takes the original positioning data as GPS original positioning data and WIFI original positioning data as an example for illustration.

[0035] Specifically, this example stores, converts, and queries GPS positioning data and WIFI positioning data through the following steps.

[0036] Step S1, the positioning device collects GPS original positioning data and WIFI original positioning data, and sends the collected GPS original positioning data and WIFI original positioning data to the server.

[0037] Step S2, the server adds corresponding marking inform...

Abstract

The invention relates to data storage, conversion and query technology, and solves the problem of low comprehensive processing efficiency of storage, conversion and query positioning data in the priorart. The technical scheme is summarized as follows: a server adds marking information to original positioning data reported by a positioning device and directly stores the original positioning data;after the original positioning data is stored, the server selectively converts the stored original positioning data, when a terminal device requests to obtain the positioning data, the server selectively converts the original positioning data in the positioning data requested by a terminal device, and finally the terminal equipment obtains all converted data. The invention has the beneficial effects that the server directly stores the reported original positioning data and shunts the conversion process of the positioning data, so that the comprehensive processing efficiency of storing, converting and inquiring the positioning data is improved.

Description

technical field [0001] The invention relates to data storage, conversion and query technology, in particular to the storage, conversion and query technology of positioning data. Background technique [0002] At present, when a positioning device uploads positioning data to the server, the uploaded positioning data is the original positioning data. For example, the original positioning data of GPS is the longitude and latitude data under the WGS84 coordinate system, and the original positioning data of WIFI is the MAC address of the WIFI device. The coordinate system used by the map is GCJ-02, so the original positioning data needs to be converted before the accurate positioning position can be obtained in the electronic map. [0003] In the prior art, after the positioning device uploads the original positioning data to the server, the server first converts each piece of original positioning data received, and then stores the converted positioning data. Due to the limited pr...
