Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] First, the system based on the present invention is briefly introduced, such as figure 1 As shown, the system mainly includes: a WIFI data collection terminal and an indoor positioning server. The WIFI data collection terminal is used to collect WIFI data through collectors, and then send it to the indoor positioning server for the indoor positioning server to use the WIFI data to build a WIFI database. Position indoors.

[0038] Since current mobile terminals usually have the functions of acceleration sensor, direction sensor (such as compass) and geomagnetic sensor in addition to the function of signal scanning, or even without these functions, it is relatively easy to add these sensors to the mobile terminal, so in In the present invent...

Abstract

The invention provides a cheating identification method and apparatus for indoor positioning signal acquisition. A WIFI data acquisition terminal, when acquiring WIFI data, also acquires at least one from acceleration data, direction data and terrestrial magnetism data; then acquired data is analyzed so as to identify situations such as acquisition personnel staying still at an original place, the acquisition personnel bumping equipment for counterfeit walking, and the acquisition personnel stimulating real walking direction within a small scope. That is to say, a manual supervision method is unnecessary, cheating identification is automatically realized, manpower and cost are saved, the accuracy of data for constructing a WIFI database is ensured, and accordingly indoor positioning quality is improved.

Description

【Technical field】 [0001] The invention relates to network technology, in particular to a cheating identification method and device for indoor positioning signal collection. 【Background technique】 [0002] At present, the main positioning method of indoor positioning is WIFI positioning, that is, the WIFI signal strength of each point in the room is collected in advance and stored in the WIFI database. When positioning, rely on the current WIFI signal strength scanned by the wireless terminal to query the WIFI database to achieve positioning. [0003] Due to the occlusion of the building, the location point corresponding to the indoor WIFI signal cannot be obtained by GPS, but can only be obtained by manual collection. The process of manual collection is mainly: the staff moves according to the predetermined collection line at a preset speed (for example, 0.5 m / s) and collects the WIFI signal strength of each location point. When the entire collection line is completed, the s...
