Embodiment Construction

[0048] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] like figure 1 As shown, the present invention describes a wireless signal acquisition and processing method for indoor positioning, which mainly includes the following steps:

[0050] S1. Collect wireless signals through a multi-directional collection strategy.

[0051] In this step, the multi-directional acquisition strategy includes collecting the signal for each point, and splitting the acquisition into several times, wherein the orientation of the positioning target in each acquisition is different, and the acquisition includes two-dimensional plane multi- Directional acquisition and multi-directional acquisition in 3D space. At ...

Abstract

The invention records a wireless signal collecting and processing method and system used for indoor positioning. The method comprises the following steps that: through a multidirectional collection strategy, collecting a wireless signal; carrying out continuous multi-time collection on each piece of wireless detection equipment in each direction in the multidirectional collection strategy; and transmitting the collected wireless signal data to a wireless positioning server to be stored and the like. The system comprises a positioning terminal module, a multifunctional wireless signal collection module and a positioning server, wherein the positioning terminal module is used for emitting an indoor positioning wireless signal; the wireless signal collection module is used for collecting multidirectional wireless signals through a multidirectional collection strategy; and the positioning server is used for receiving and storing the wireless signal collected by the multifunctional wirelesssignal collection module. Due to the above technology, on the basis of the change difference characteristics of the wireless signal in different directions, a multidirectional signal collection strategy is adopted. Meanw

Description

technical field [0001] The present invention relates to the technical field of indoor wireless positioning, and in particular to a method and system for collecting and processing wireless signals based on the characteristics of changes in wireless signals in different directions and adopting processing mechanisms such as multi-directional signal collection and noise reduction selection. Background technique [0002] With the development of science and technology and the popularity of smart devices, the positioning system based on wireless signals has also developed rapidly. Generally speaking, the process of using wireless signal strength to obtain target location information is the process of establishing a stable mapping relationship between wireless signals and location information. Existing indoor wireless positioning systems are mainly realized by short-distance wireless technologies such as infrared, ultrasonic, Bluetooth, WIIF, and RFID. [0003] Among them, the wire...
