Abstract

The invention provides an indoor positioning self-adaptive sampling method. The method is characterized in that a periodically triggered self-adaptive database updating period, a sampling transmission interval and the characteristic quantity difference threshold updated by a self-adaptive database triggered by an event are configured through a network side. When a system detects that the database satisfies the condition of the periodic updating or the event updating, sampling instructions are sent through a network side sampling terminal to instruct the sampling terminal to transmit a wireless signal according to the network side configuration, and the network side extracts a wireless signal characteristic quantity of the sampling terminal and dynamically updates the present database. The method enables the system to match dynamic changes of a wireless environment in a self-adaptive mode, and raises the indoor positioning precision of the system.

Description

technical field [0001] The invention belongs to the field of indoor positioning and short-distance communication. Background technique [0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. In addition to the cellular positioning technology of the communication network, common indoor wireless positioning technologies include: Wi-Fi, Bluetooth, infrared, ultra-wideband, RFID, ZigBee and ultrasonic. [0003] The fingerprint matching (RFPM) method is an important means in indoor and outdoor positioning, especially in the application of indoor positioning, it has a wide range of application scenarios, such as shopping mall positioning, exhibition positioning, office building positi...
