Problems solved by technology

[0007] In order to solve the above technical problems, the object of the present invention is to provide an indoor comprehensive positioning method. When the indoor environment cannot use satellite positioning, the indoor positioning technology is used as the auxiliary positioning of satellite positioning, so as to solve the problem that when the satellite signal reaches the ground, it is weak and cannot pass through. Through the problem of building, finally locate the current position of the object

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] see figure 1 , a kind of indoor comprehensive positioning method described in a preferred embodiment of the present invention, comprises the following steps:

[0025] (1), within the preset time, obtain RSSI data and user authentication data; wherein, the RSSI data includes the AP RSSI data of the network end and the Bluetooth RSSI data of the user end, and the user authentication data is the user authentication data of the network end, that is, through different channels Get various data of the same target object.

[0026] (2), RSSI data and user authentication data are calculated into location data respectively; Concretely, the AP RSSI data part of the network e...

Abstract

The invention relates to an indoor comprehensive positioning method. The method comprises the following steps: acquiring RSSI data and user authentication data within a preset time; 2, respectively calculating the RSSI data and user authentication data into position data; and 3, carrying out weighting fusion on all the position data by using a preset positioning result model in order to obtain the final positioning result of a target object. Multiple pieces of positioning information of a network terminal and a user terminal are integrated to mutually fuse different positioning technologies, so compared with individual positioning technologies, the method greatly improves the timeliness and the precision of positioning and greatly improves the indoor positioning effect without increasing the investment.

Description

technical field [0001] The invention relates to the field of wireless positioning, in particular to an indoor comprehensive positioning method. Background technique [0002] With the advent of the information age, communication and navigation technology has developed rapidly. The close integration of navigation system and communication system makes the navigation and positioning information of individual users generate greater application value and exert more efficiency. In indoor environments where navigation satellite signals are difficult to cover, wireless positioning technology can be divided into: range free and range based, according to whether distance measurement is performed during positioning. Commonly used ones based on ranging are: based on received signal strength RSSI (Received Signal Strength Indication) and based on time difference of arrival TDOA (Time Difference of Arrival). [0003] The so-called RSSI positioning technology is to estimate the positioning...
