Triangulation, method for retrieving bluetooth device, bluetooth device and positioning system

Abstract

The present invention provides a method for triangulating a target Bluetooth device, a method for retrieving a target Bluetooth device, a Bluetooth device and a system for triangulating a target Bluetooth device, wherein the method applied to the second Bluetooth device includes: Step 101: in the positioning mode When turned on, set its own positioning role as the moving device, the first Bluetooth device as the anchor device, and the target Bluetooth device as the lost device; Step 103: Obtain the first distance value (L 1 ), and the third distance value (L 3 ); Step 105: Receive the second distance value (L 2 ); Step 107: in |L 3 ‑L BA |<ε 3 , and |L 1 ‑L BC |<ε 1 When both are established, a prompt message to fix its own position (B) will be issued. In the present invention, the user operates and moves a bluetooth device, and after receiving fixed information, the lost bluetooth device is retrieved by knowing the positions of the two bluetooth devices and the preset triangular relationship.

Description

technical field [0001] The invention relates to the field of Bluetooth technology, in particular to a method for triangulating a target Bluetooth device, a method for retrieving a target Bluetooth device, a Bluetooth device and a system for triangulating a target Bluetooth device. Background technique [0002] With the development of Bluetooth technology, some small-sized products equipped with Bluetooth technology are becoming more and more common. For example, a true wireless Bluetooth headset (TWS, True Wireless Stereo). But it is precisely because of its small size that compared with wired earphones, true wireless earphones are easy to lose and more difficult to retrieve after being lost. Except for charging in the charging box, true Bluetooth earphones are often thrown aside. After a period of time, There is a good chance that a user will not be able to find a single or an entire pair of true Bluetooth headsets. When a true bluetooth headset is lost, most users will b...

Problems solved by technology

However, due to their small size, compared with wired earphones, true wireless earphones are easy to lose and are more difficult to find after being lost. In addition to putting them in the charging box for charging, true Bluetooth earphones are often left aside. After a period of time, It is very likely that users will not be able to find a single or entire pair of true Bluetooth headsets

When a true bluetooth headset is lost, most users will buy a new set of bluetooth headsets (including charging box, left earphone and right earphone) in case of urgent need. easy to find again

This results in wasted money and a bad mood, affecting the user experience
