Problems solved by technology

In real life, accidental missing children occur frequently. Therefore, parents must keep an eye on their children when they go shopping. When chatting with acquaintances, it is inevitable to neglect the child, so it is very easy for the child to get lost accidentally. Once the child is lost, it will be an unbearable disaster for the whole family

Embodiment 1

[0045] See figure 1 The embodiment of the present invention discloses an anti-lost method based on Bluetooth technology, which is applied to an anti-lost terminal to realize timely retrieval when the monitored person leaves a safe distance to avoid accidental loss of the monitored person. The method includes:

[0046] Step 100: After connecting with monitoring terminal #1~#N (N≥2) via Bluetooth, use RSSI technology to determine in real time whether the anti-lost terminal has departed from the safety range jointly determined by monitoring terminal #1~#N; if so , Go to step 200; otherwise, go back to step 100;

[0047] Wherein, the safety range determined by the monitoring terminal #I (N≥I≥1) is a circle with its geographic location as the center and r (r<Bluetooth signal coverage radius R) as the radius.

[0048] Step 200: Notify the monitoring terminals of the N monitoring terminals that also have Bluetooth connections with the anti-lost terminal to issue a warning reminder.

[0049] ...

example 1

[0052] Example 1: The father with monitoring terminal #1 and the mother with monitoring terminal #2 take the child with the anti-lost terminal to the park for a walk. Once the child runs out of the safety range jointly determined by the monitoring terminal #1~#2 (I.e. as an area where parents can move freely), there are three processing situations: 1) If the anti-lost terminal is within the search range of monitoring terminal #1 but out of the search range of monitoring terminal #2, then monitoring terminal # 1 A warning will be issued to remind the father to retrieve the child in time to prevent accidental loss of the child; 2) If the anti-lost terminal is within the search range of monitoring terminal #2 but out of the search range of monitoring terminal #1, monitoring terminal #2 will A warning is issued to remind mothers to retrieve the child in time; 3) If the anti-lost terminal is within the search range of monitoring terminal #2 and within the search range of monitoring t...

example 2

[0053] Example 2: Mom and Dad took two children to catch the train at the train station. Because the train station was crowded with people of all colors, in order to avoid the two children being abducted by criminals when the mother was busy looking after the luggage and the father was busy buying tickets. Two children can each carry an anti-lost terminal. Each anti-lost terminal establishes a Bluetooth link with the monitoring terminal carried by mom and dad respectively. When any child is taken out of the area considered by mom and dad to be free, the corresponding The monitoring terminal of the company will issue a warning, so that it is convenient to catch criminals in time and prevent children from being abducted.

Abstract

The invention discloses a Bluetooth technology-based anti-lost method, terminal, system and monitoring terminal. The method is applied to an anti-lost terminal, and includes the following steps: after connection with N monitoring terminals through Bluetooth, an RSSI technology is utilized to judge in real time whether the anti-lost terminal is away from a safe range jointly determined by the N monitoring terminals; N>=2, and a safe range determined by each of the monitoring terminals is a circle with the geographical position of itself being the center of the circle and a value smaller than a Bluetooth signal coverage radius being a radius; and if the anti-lost terminal is judged to be away from the safe range, the monitoring terminals which are still in Bluetooth connection with the anti-lost terminal among the N monitoring terminals are notified to sent out a warning for reminding. By adoption of the Bluetooth technology-based anti-lost method, a monitored person can be found in time when being away from a safe distance, thereby avoiding occurrence of an event that the monitored person gets lost accidentally.

Description

Technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to an anti-lost method, terminal, system and monitoring terminal based on Bluetooth technology. Background technique [0002] Children are easily lost due to poor self-protection ability and awareness. In real life, accidents of children getting lost frequently occur. Therefore, parents must keep an eye on their children when they take their children out to shop. However, children’s nature likes to run around. In addition, parents are shopping for goods, paying or meeting When chatting with acquaintances, it is inevitable to neglect the child, so it is very easy to accidentally lose the child. Once the child is lost, it will be an unbearable disaster for the whole family. Summary of the invention [0003] In view of this, the present invention provides an anti-lost method, terminal, system and monitoring terminal based on Bluetooth technology to realize timely retrie...
