Problems solved by technology

[0002] The current wireless positioning technology is a first-level positioning method, that is, positioning the target once, using a single technical form, such as GPS positioning, GSM base station positioning, WiFi positioning, Zigbee positioning, etc.
These positioning methods have their own advantages and disadvantages: GPS positioning is accurate, but once the mobile terminal enters the room, it cannot be positioned; GSM base station has a large positioning range and is not restricted by indoors, but the positioning accuracy is too low, and the positioning accuracy is generally above 50 meters ;WiFi positioning, Zigbee positioning and other positioning methods have high accuracy (2 meters to 50 meters), but the positioning range is small.

Embodiment Construction

[0015] The present invention is further described below.

[0016] The mobile terminal multi-level positioning method of the present invention comprises the following steps:

[0017] The positioning range is divided into multiple levels: R1, R2.....Rn, among which: R1>R2...>Rn; the positioning range of positioning method 1 is R1, and the positioning accuracy is P1; the positioning method 2 The range is R2, and the positioning accuracy is P2;,......, the positioning range of positioning method n is Rn, and the positioning accuracy is Pn; when Pn>......>P2>P1:

[0018] Step 1: Use positioning method 1 to locate the mobile terminal for the first time within the positioning range of R1, determine the position of the mobile terminal, and the positioning accuracy is P1;

[0019] Step 2: within the determined P1 accuracy range, use the positioning method 2 with a positioning accuracy of P2 to perform positioning, further determine the position of the mobile terminal, and improve the ...

Abstract

The invention discloses a multistage positioning method for a mobile terminal. In the method, the mobile terminal is rapidly roughly positioned by adopting a global system for mobile communication (GSM) base station positioning method, and in a range determined by a GSM base station, the GSM mobile terminal is accurately positioned by adopting a WiFi/ZigBee positioning technology. The invention also discloses a device adopting the multistage positioning method. The device comprises a host and a submachine. A GSM base station positioning module and a WiFi/ZigBee positioning module are installed on the submachine. A master control module is installed on the host, and is used for controlling the working conditions of the GSM base station positioning module and WiFi/ZigBee positioning module of the submachine. In the method and the device, a plurality of positioning methods are combined so as to effectively eliminate conflicts between the positioning range and positioning accuracy of the mobile terminal.

Description

technical field [0001] The invention relates to radio positioning technology, in particular to a mobile terminal multi-level positioning method and device. Background technique [0002] The current wireless positioning technology is a first-level positioning method, that is, positioning the target once, using a single technical form, such as GPS positioning, GSM base station positioning, WiFi positioning, Zigbee positioning and other methods. These positioning methods have their own advantages and disadvantages: GPS positioning is accurate, but once the mobile terminal enters the room, it cannot be positioned; GSM base station has a large positioning range and is not restricted by indoors, but the positioning accuracy is too low, and the positioning accuracy is generally above 50 meters ;WiFi positioning, Zigbee positioning and other positioning methods have high accuracy (2 meters to 50 meters), but the positioning range is small, which belongs to the short-distance positio...
