Embodiment 1

[0042] See figure 1 The present invention discloses an area positioning system for positioning the mobile terminal 10; the positioning system includes the mobile terminal 10, a number of positioning reference stations 20, and a number of positioning processing modules 30. One of the mobile terminal 10 and the positioning reference station 20 is a positioning signal transmitting module, and the other is a positioning signal receiving module. In this embodiment, the mobile terminal 10 is a positioning signal transmitting module, and the positioning reference station 20 is a positioning signal receiving module; of course, the positioning reference station 20 may transmit the positioning signal, and the mobile terminal 10 receives the positioning signal. In addition, the mobile terminal 10 and the positioning reference station 20 may both have the functions of transmitting and receiving positioning signals, and may also have other wireless communication functions. The wireless commun...

Embodiment 2

[0056] Please refer to image 3 The difference between this embodiment and the first embodiment is that in this embodiment, the mobile terminals are mobile phones 10A, 10B with positioning functions, the positioning reference stations are GMS base stations 20A, 20B, 20C, and the positioning processing module is installed in the positioning computer 30. Positioning processing software. Then the positioning method of the present invention for the area positioning system of the GSM mobile communication network includes the following steps:

[0057] Step A. The mobile phone 10 transmits a positioning signal, the strength of the positioning signal changes regularly within a certain period, and the transmitted positioning signal contains intensity information, and the strength of the positioning signal is roughly proportional to its range. In this embodiment, the period of regular changes in the positioning signal is 2 seconds, and a positioning signal is sent every 0.5 seconds. The sig...

Embodiment 3

[0062] See Figure 4 This embodiment introduces an area positioning system and method for a short-range wireless communication network in a local area. The difference between this embodiment and the first embodiment is that this embodiment is mainly used for regional positioning of a short-range wireless communication network in a local area. In this embodiment, the mobile devices are positioning cards 10A, 10B, and 10C, the positioning reference station is a card reader 20, and the positioning processing module is positioning processing software installed in the positioning computer 30.

[0063] In this embodiment, the period of regular changes in the positioning signal is 2 seconds, and a positioning signal is sent every 0.5 seconds. The signal strength is from strong to weak, respectively 4, 3, 2, 1, and the corresponding range (radius) It is 50 meters, 25 meters, 10 meters, and 5 meters.

[0064] If the minimum positioning signal strength received within a period (2 seconds) is...

Abstract

The invention discloses an area positioning system for positioning a mobile terminal, which comprises the mobile terminal, a positioning reference station and a positioning processing module. One of the mobile terminal and the positioning reference station is a positioning signal transmitting module while the other one is a positioning signal receiving module, wherein the positioning signal transmitting module is used for transmitting a positioning signal; the positioning signal receiving module is used for receiving the positioning signal transmitted from the positioning signal receiving module and delivering the positioning signal to the positioning processing module to carry out analysis processing; and the positioning processing module is used for judging the intensity of the receivedpositioning signal with the minimum intensity and judging the distance between the positioning signal transmitting module and the positioning signal receiving module according to the minimum intensity of the positioning signal to obtain a position range of the mobile terminal. The invention maintains the usability and the low cost of the area positioning and improves the positioning precision so as to ensure that the area positioning technology can be used in more application occasions.

Description

Technical field [0001] The present invention belongs to the field of communication technology, and relates to an area positioning system, in particular to an area positioning system that utilizes connectivity for positioning. In addition, the present invention also relates to the area positioning method of the above-mentioned area positioning system. Background technique [0002] With the development of wireless technology, the positioning technology through wireless technology has also been continuously developed and its applications have become more and more extensive. Currently, wireless positioning technologies are roughly divided into several types, including regional positioning, signal strength of arrival (RSSI), time of arrival (TOA), and time difference of arrival (TDOA). The positioning accuracy and implementation cost of various positioning technologies are different. Generally speaking, the higher the positioning accuracy, the higher the implementation cost. Among the...
