Embodiment 1

[0062] Embodiment 1: Indoor positioning with the signal receiving unit as the object to be positioned

[0063] In the prior art, when GPS signals are used for positioning indoors, GPS positioning cannot be accurately realized due to the limitation of closed spaces of venues. In addition, the altitude information contained in the GPS positioning information does not necessarily have practical application significance in indoor positioning. The present invention uses wireless signals as the basis for indoor positioning. When positioning indoors, the present invention divides the indoor space according to the importance of the regions, or according to the positioning accuracy requirements.

[0064] In this embodiment, the signal transmitting unit 1 is fixedly arranged in the space 6 . Such as image 3 As shown, a certain indoor space 6 is divided into four areas, namely area A, area B, area C, and area D. Three signal transmitting units 1 are arranged in area A, area B, and ...

Embodiment 2

[0073] Embodiment 2: outdoor positioning of the signal transmitting unit as the object to be positioned

[0074] The present invention can be used for outdoor positioning, such as outdoor exhibitions or outdoor exhibitions. At present, the positioning accuracy of the common civilian GPS positioning system is about 10M, which is difficult to meet the needs of precise positioning in small and medium-sized outdoor exhibitions. In view of the open space of the outdoor exhibition hall, in this embodiment, the signal transmitting unit 1 is used as the object to be positioned, for example, the signal transmitting unit 1 is set in the mobile terminal of the user of the object to be positioned. The signal transmitting unit 1 will continuously transmit a constant intensity wireless signal with an identifier to the surroundings. The mobile terminal is also provided with a display unit 5, and the display unit 5 displays the area where the user is located.

[0075] In this embodiment, th...

Embodiment 3

[0085] Embodiment 3: Positioning area division

[0086] The present invention can perform space division according to different actual needs when positioning indoors or outdoors. The positioning accuracy of the present invention can be freely set and optimized according to specific application requirements. For example, it is divided into important positioning areas and non-important positioning areas. The positioning error of the entire positioning space is not uniform. Area division and processing can be performed in important positioning areas (such as high-density positioning areas), and rough positioning can be completed in non-important positioning areas. For example, in a certain museum, there are multiple exhibits displayed in the exhibit area, and the area where each exhibit is located needs to be accurately positioned, and visitors do not need to be accurately positioned in the rest area. Therefore, the exhibit area is divided into important positioning areas, and ...

Abstract

The invention discloses a signal positioning system comprising at least one signal emission unit used for emitting wireless signals, at least one signal receiving unit used for measuring the wireless signals to obtain signal measurement data, at least one processing unit connected to the signal receiving unit and used for receiving and processing the signal measurement data, and a database unit connected to the processing unit and used for storing information needed by a storage positioning algorithm. According to the signal positioning system and the positioning method thereof of the invention, through a signal area positioning method, a realizable application scope of the existing positioning system is enlarged, and the accuracy and feasibility are improved. Furthermore, according to demands of practical application, variable positioning accuracy degrees are provided, so that the operation efficiency is raised. According to the signal positioning system and the positioning method thereof of the invention, dependence on trilateration or triangulation in the prior art are eliminated. The application scope is enlarged and the operation efficiency is raised. The invention also brings forward a positioning method of the signal positioning system.

Description

technical field [0001] The invention belongs to the technical field of positioning systems, and in particular relates to a signal positioning system and a positioning method thereof. Background technique [0002] GPS provides global coverage outdoors, but indoor applications are very limited due to signal shielding. Second, the GPS regards the entire positioning space as a uniform coordinate system, that is, it cannot separately or prioritize important and non-important areas and distances. That is, when it is necessary to distinguish between important areas and non-important areas, or when areas and distances cannot be distinguished or prioritized, the positioning error in the entire range is uniform, at this time, the above-mentioned shortcomings of the prior art will adversely affect many practical applications. [0003] Existing local positioning systems (whether based on wireless signals or other technologies) require at least three signal sources or signal receivers ...
