A method and system for realizing over-area alarm

Abstract

The invention discloses a method for realizing over-zone alarm. Blue-tooth low energy (BLE) primary devices are configured with white lists, and BLE secondary devices positioned in the white lists can communicate with the BLE primary devices; the BLE secondary devices periodically send non-connectable broadcasts, and the BLE primary devices report address information of the BLE secondary devices corresponding to the non-connectable broadcasts to a background system after scanning the non-connectable broadcasts; the background system maintains an over-zone alarm timer corresponding to each BLE secondary device, and the background system restarts the corresponding over-zone alarm timer if the background system receives reported address information of a certain secondary device; and if the over-zone alarm timer is overtime, the background system sends over-zone alarm information of the BLE secondary device corresponding to the over-zone alarm timer. The invention also discloses a system for realizing over-zone alarm. According to the method and system for realizing over-zone alarm, over-zone alarm can be realized by the white lists without establishment of blue-tooth connection; the secondary devices are in an ultra-low power consumption state all the time, in such a way that power saving of the secondary device can be achieved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a method and system for realizing cross-region alarm. Background technique [0002] Bluetooth is a radio technology that supports short-range communication (generally within 10m) of devices. It can carry out wireless information exchange between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. Using the characteristics of wireless signal attenuation with distance, based on Bluetooth technology, it can realize cross-regional alarm to prevent people from getting lost or items from being lost. [0003] In the prior art, the implementation process of cross-region alarm is as follows: a Bluetooth connection is established between the Bluetooth master device and the Bluetooth slave device. Alarms can be issued from the device. The disadvantage of this solution is that the effective active area of ​​t...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is that the effective active area of ​​the slave device is limited to the communicable distance of a certain master device, so the range is small; and the Bluetooth connection needs to be maintained, and the power consumption of the device is high

[0004] In the prior art, there is also a cross-region alarm method based on Bluetooth positioning technology: based on the received signal strength indication (RSSI, Received Signal Strength Indication) measurement technology, the device location or related information is reported to the background system, and the background system passes through the positioning algorithm. , through the location information to judge whether it is out of the area, the disadvantage of this solution is that the implementation is more complicated, it needs to carry out the process of measurement and reporting, and the background system needs to implement a more complex positioning algorithm
