Description

Method and device for transmitting positioning information of lost persons

technical field

The invention relates to the fields of image recognition technology and communication technology, in particular to a method and device for transmitting positioning information of a lost person.

Background technique

Existing positioning technologies for lost persons mainly include GPS positioning and Bluetooth positioning. GPS positioning uses geosynchronous satellites to provide users with an all-weather, regional satellite positioning system to quickly determine the target or the user's geographic location. Bluetooth positioning is to use Bluetooth pairing to confirm its location through effective distance. Others, such as ultra-wideband (UWB) positioning technology, Wi-Fi positioning technology and radio frequency identification positioning technology, etc., all need to transform the surrounding environment to achieve precise positioning functions.

According to the survey of most scenes where people get lost, they are mainly concentrated in indoor environments such as shopping malls and supermarkets. Parents often focus on shopping for goods, trying on clothes, checking out, etc., and tend to neglect to take care of their children. Children are easily out of the sight of their parents because of the flow of people. Moreover, there are many space partitions in the supermarket, and the display of the counters is similar, so it is not easy for children to distinguish them, and it is easier to get lost.

GPS positioning is more suitable for outdoor scenes with a wide view and fewer obstacles. This is related to the penetration of the signal when the GPS locator receives the GPS signal, because these roofs and floors made of reinforced concrete block the The transportation of the GPS receiving signal, so the GPS locator will have a weak signal or even no signal indoors.

The Bluetooth positioning method mainly uses the broken link mechanism to provide early warning of the child's location, but because the Bluetooth connection distance is too limited, the current civilian version of the Bluetooth distance is between 8-30m, and most mobile phones and mobile devices now use the Bluetooth technology PowerClass2 which is the farthest The distance is 10 meters, which will mainly cause the disconnection trigger of the Bluetooth connection to be more frequent, and often cause risky false alarms on the location of children, resulting in inconvenient use.
