Problems solved by technology

The above methods have limitations. The signal attenuation of the GPS satellite signal is very serious indoors on the floor, and the positioning chip cannot be located. However, items such as keys and wallets are often left indoors. If they were picked up outdoors, this kind of indoor The situation is that it is impossible to search for and locate the item
The mobile phone Bluetooth communication search can only be used in short distances, and can only be used when the indoor location of the known object is known, and it cannot be searched in a long-distance and timely manner.

Abstract

The invention relates to an article searching and positioning method and system, belongs to the technical field of article positioning, and particularly relates to the technical field of rapid positioning. The system comprises a positioning searching device and searching APP software based on a smart phone, and when an object is searched, a searching instruction is sent through the searching APP software based on the smart phone and a mobile communication network; and the positioning search device receives and responds to a search instruction sent by the smart phone. The article searching andpositioning device is composed of only several chips, is small in size, can be made into a key pendant and hung on a key chain, can also be made into a card form to be placed in a wallet, and is convenient to use.

Description

technical field [0001] The invention relates to a method and system for searching and locating an object, belonging to the technical field of object positioning, in particular to the technical field of rapid positioning. Background technique [0002] The existing patents either locate the key / wallet through the built-in GPS positioning chip, or activate the sound or light through the Bluetooth communication of the mobile phone to locate the key indoors. The above methods have limitations. The signal attenuation of the GPS satellite signal is very serious indoors on the floor, and the positioning chip cannot be located. However, items such as keys and wallets are often left indoors. If they were picked up outdoors, this kind of indoor The situation is that it is impossible to search for and locate the item. The mobile phone Bluetooth communication search can only be used in short distances, and can only be used when the indoor place of the known item is known, and cannot be ...
