Method and system for an intelligent alarm

Abstract

The invention discloses a method and a system for achieving intelligent alarming. The method for achieving the intelligent alarming includes: under a calibration mode, obtaining a distance between a first terminal and a second terminal, building a short distance communication connection between the first terminal and the second terminal, establishing a corresponding relationship between the distance and wireless signal strength in the short distance communication connection, obtaining a wireless signal strength alarm threshold value corresponding to a preset warning distance according to the corresponding relationship, and sending first alarm if the obtained wireless signal strength is less than the wireless signal strength alarm threshold value after quitting the calibration mode. The method for achieving the intelligent alarming obtains the relationship between the wireless signal strength and the distance between the first terminal and the second terminal through unique identification information of the second terminal, can monitor the distance between the first terminal and the second terminal by monitoring the wireless signal strength, achieves a losing prevention reminding function, and prevents distance detection error caused by individual differences of wireless power of all devices.

Description

technical field [0001] The invention relates to the technical field of short-distance wireless communication applications, in particular to an intelligent alarm method and system. Background technique [0002] Short-range wireless communication technology has penetrated into all aspects of people's life and work, including mobile phones and wireless phones used in daily life. Among them, Bluetooth is widely used due to its low power consumption, high-efficiency data transmission, and high connection stability. [0003] At present, many smart watches or wristbands are used in conjunction with mobile phones, and realize the anti-lost function through wireless networks such as Bluetooth. When the distance exceeds a certain distance, it will automatically alarm to remind the two connected parties to prevent the distance from being too far and play an anti-lost reminder effect. [0004] The wireless network used by the anti-lost reminder function is generally Bluetooth or WIFI, ...

AI Technical Summary

Problems solved by technology

[0004] The wireless network used by the anti-lost reminder function is generally Bluetooth or WIFI, but because of the differences in the transmission power and structure of various wireless devices of different mobile phones and different models, the anti-lost reminder function software cannot adapt to many different mobile phones at the same time, and is sensitive to some distances Due to the difference in the transmission power and structure of each wireless device, it will lead to a large detection error, which has great risks and inconveniences, and cannot achieve a good anti-lost reminder effect.
