Embodiment 1

[0022] The embodiment of the present invention provides a positioning system based on wireless communication.

[0023] figure 1 It is a schematic diagram of a positioning system based on wireless communication according to an embodiment of the present invention. Such as figure 1 As shown, the positioning system based on wireless communication includes: a positioner 10, a radio frequency reader / writer 20, and a processor 30.

[0024] The locator 10 is used for locating the target object through GPS and determining the initial position range of the target object, where the target object is the object to be located.

[0025] The locator 10 determines the preliminary position range of the target object through GPS, so as to find the rough position of the target object. The locator 10 sends a preliminary location request for the target object to the remote server. Preferably, the remote server stores the position range information of the target object determined by GPS, and the position...

Embodiment 2

[0040] According to the embodiment of the present invention, an embodiment of a positioning method based on wireless communication is also provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions And, although the logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here.

[0041] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, figure 2 It is a hardware structure block diagram of a computer terminal running a positioning method based on wireless communication according to an embodiment of the present invention. Such as figure 2 As shown, the computer terminal A may include one or more (only one is shown in the fig...

Embodiment 3

[0071] The embodiment of the present invention also provides a wireless communication-based positioning device for implementing the above-mentioned wireless communication-based positioning method.

[0072] Figure 4 It is a schematic diagram of a positioning device based on wireless communication according to the first embodiment of the present invention. Such as Figure 4 As shown, the positioning device based on wireless communication includes: a first determining unit 40, a reading unit 50, a detecting unit 60, a second determining unit 70, and a positioning unit 80.

[0073] The first determination unit 40 locates the target object through GPS, and determines the initial position range of the target object, where the target object is the object to be located.

[0074] The reading unit 50 is configured to read the radio frequency signal emitted by the electronic tag through the radio frequency reader within the preliminary position range, where the electronic tag is set on the tar...

Abstract

The invention discloses a positioning method, device and system based on wireless communication. The method comprises the steps: positioning a target object through a GPS, and determining a preliminary position range where the target object is located, wherein the target object is a to-be-positioned object; reading a radio-frequency signal transmitted by an electronic tag in the preliminary position range through a radio-frequency reader-writer, wherein the electronic tag is disposed on the target object, and the target object is the to-be-positioned object; detecting the signal intensity of the radio-frequency signal read by the radio-frequency reader-writer; determining the relative position information of the radio-frequency reader-writer and the electronic tag according to the signal intensity of the radio-frequency signal; and carrying out the positioning of the target object according to the relative position information of the radio-frequency reader-writer and the electronic tag. According to the invention, the method, device and system solve a technical problem that the positioning precision of a target object is low.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a positioning method, device and system based on wireless communication. Background technique [0002] At present, when the target object needs to be located, the target object is located by acquiring the position information of the target object, and then the target object is searched. When locating the mobile communication terminal, by logging in to the remote server, the location information of the mobile communication terminal is obtained from the remote server. For example, the "Find My Iphone" application software is installed on the Apple mobile phone, and the user terminal enters the account name and login password of the Apple mobile phone to be located on the login interface of the "Find My Iphone" application software to log in to the Apple cloud service platform. After successfully logging in to the Apple cloud service platform, the Apple mobile phone successfully est...
