Embodiment Construction

[0030] like figure 1 As shown, an embodiment of the present invention is shown, an indoor positioning device, including:

[0031] The electromagnetic signal transceiver module 100 is configured to send electromagnetic signals to N reference points in the room, and obtain first power data of the electromagnetic signals fed back by the reference points, where N is an integer not less than 9.

[0032] Specifically, the staff pre-sets at least nine reference points 1, 2...N on the door, window, center, and four corners of the site, and each reference point includes an electromagnetic signal transceiver. After the target object enters the place with the indoor positioning device of the present invention, the electromagnetic signal transceiver module 100 sends out an electromagnetic signal, which is received by each reference point in the place, and detects the power data of the received electromagnetic signal, that is, the first power data, Feedback to the electromagnetic signal t...

Abstract

The invention relates to an indoor positioning apparatus, method and system. First power data of at least nine reference points are detected through an electromagnetic signal transmitting-receiving module. Designated reference points are selected according to stored designated reference point position data and the first power data. The position of a target object is located according to the designated reference point position data, the distance between every two designated reference points and the acquired first power data and second power data. Simple and accurate positioning can be achieved. A low cost is further realized.

Description

technical field [0001] The present invention relates to the field of navigation and positioning, in particular to an indoor positioning device, method and system. Background technique [0002] At present, the global positioning system is used by all walks of life, but it has an obvious defect - when the satellite signal reaches the ground, it is weak and cannot penetrate buildings. It can only be positioned outdoors, not indoors. The accuracy is only about 10m, which is still a long way from the indoor navigation requirement of about 1m. With the popularity of smart phones and the development of mobile Internet, map and navigation software will enter a new era - indoor navigation. [0003] In recent years, some technology giants including Google, Microsoft, Apple, Broadcom, etc., and some world-renowned universities have been researching indoor positioning technology. Indoor positioning technology has reached the point where the target object's position data and motion fea...
