Problems solved by technology

[0003] Most of the current positioning systems are aimed at absolute position positioning, such as argos terminals and GPS collars for tracking wild animals, watch GPS for personal positioning and track recording, etc. These devices have complex systems, high costs, and Disadvantages such as requiring map support and / or being one-way communication
Household equipment that realizes short-distance relative position positioning is still blank in the current market

Embodiment 1

[0050] In the wireless relative positioning method of the present invention, the first positioning device with the radio receiving / transmitting function is associated with the second positioning device with the radio receiving / transmitting function in a code pairing manner, and the ID code is determined by the group ID Code and device ID code. The associated steps are:

[0051] The first positioning device generates a random code composed of a group ID code and a device ID code as the first positioning device's own No. 1-1 ID code, and stores the No. 1-1 ID code and / or the corresponding identification in the In the storage unit of the first positioning device itself;

[0052] The first positioning device sends the stored No. 1-1 ID code to the second positioning device, and after the second positioning device receives the No. 1-1 ID code, the second positioning device randomly generates its own device ID code; the second positioning device The device uses the received group ...

Embodiment 2

[0061] On the basis of Embodiment 1, when the measurement environment includes multiple positioning devices of the same group, the associated steps are:

[0062] The first positioning device generates a random code composed of a group ID code and a device ID code as the first positioning device's own No. 1-1 ID code, and stores the No. 1-1 ID code and / or the corresponding identification in the In the storage unit of the first positioning device itself;

[0063] The first positioning device sends the stored No. 1-1 ID code to the second positioning device, and after the second positioning device receives the No. 1-1 ID code, the second positioning device randomly generates its own device ID code; the second positioning device The device uses the received group ID code in the 1-1 ID code sent by the first positioning device and the device ID code randomly generated by the second positioning device as the 2-1 ID code of the second positioning device itself, and Matching and stor...

Embodiment 3

[0075] When the measurement environment includes different groups of the second positioning device and the third positioning device, after the first positioning device is associated with the second positioning device in the manner as in Example 2, whether the first positioning device is in the same group as the second positioning device The third positioning device association steps are:

[0076] The first positioning device generates another random code composed of a group ID code and a device ID code as the ID code No. 1-2 of the first positioning device itself, and stores this ID code and / or corresponding identification in the first In the storage unit of the positioning device itself;

[0077] The first positioning device sends the stored No. 1-2 ID code to the third positioning device, and the third positioning device receives and matches the No. 1-2 ID code sent by the first positioning device with the corresponding identification of the first positioning device storage...

Abstract

The invention relates to a radio relative positioning method and device. The method comprises the following steps of: associating a first positioning device with a radio receiving / sending function with a second positioning device with a radio receiving / sending function in a coding manner, receiving a radio wave carrying an ID code and an sending time sent by the second positioning device through an antenna array by the first positioning device; by taking the first positioning device as an original point, orienting and ranging the second positioning device in real time by receiving the radio wave and computing time difference; meanwhile, displaying the orienting and ranging results through a display unit of the first positioning device. By the method and the device disclosed by the invention, the relative positioning between two points can be realized without using a GPS satellite, a base station or a third-party auxiliary device when more people are on travel; therefore, stray people can gather with nearby companions conveniently, and the risk of getting lost is reduced; especially, the method and the device are very useful in an environment the visitor flow is large and the vision / listening is difficulty to use.

Description

technical field [0001] The invention relates to a method and equipment for relative positioning by using radio waves. Background technique [0002] With the development of cities and the expansion of population, a large number of people often appear in some public places, especially tourist attractions. Especially during holidays such as weekends or holidays, public places are densely populated and have a large circulation. And it is people's favorite way of leisure to travel or go out with family or friends. When visiting scenic spots or parks, or on the way, due to different points of interest, inconsistent pace or occasional distraction, coupled with the impact of crowds, people in the same company often get separated or lost. Paying attention to your companions along the way increases the burden of travel, but it cannot completely avoid the separation of yourself or your companions. Especially for the case of bringing children, once separated, facing the vast crowd, t...
