Bluetooth communication-based falling-off alarm system and alarm method thereof

Abstract

The invention discloses a Bluetooth communication-based falling-off alarm system and an alarm method thereof. According to the Bluetooth communication-based falling-off alarm system and the alarm method thereof, a mobile application (APP) is used in cooperation, a built-in falling-off detection device only needs to perform data detection, and data processing and alarm operation are completed by the mobile APP, and therefore, the method is simple, and development difficulty is low, and the advantages of a smart phone can be fully utilized, and multi-mode alarm can be realized; low-battery alarm prompting of the falling-off detection device and mobile phone forgetting prompting can be performed through the mobile APP, and therefore, the old people will not forget to take smart phones, and therefore, the Bluetooth communication-based falling-off alarm system and the alarm method thereof have high applicability; falling-off situations are judged through parameters such as angle, displacement and time; comprehensive judgment can be performed through falling-off data of two falling-off detection devices in shoes, insoles or socks, and therefore, unnecessary false alarm can be avoided, and falling-off detection accuracy is high; the falling-off detection equipment is wrapped by a high-strength plastic shell, so that the falling-off detection equipment has waterproof and anti-shock functions, and standby time of a built-in power source is long.

Description

technical field [0001] The invention relates to the field of call alarms, in particular to a fall alarm system and an alarm method suitable for the elderly and based on bluetooth communication. Background technique [0002] Falls are often catastrophic events for older adults that can seriously affect their health and often require years to full recovery, if not a lifetime. Especially for the elderly who suffer from cardiovascular and cerebrovascular diseases, once they suddenly fall ill, if no one finds out in time, the rescue time will be delayed and life-threatening. In order to realize the timely alarm when the elderly fall, there are many kinds of fall detection and alarm equipment with fall alarm function in the existing technology, such as wearable fall alarm equipment, fall alarm shoes, hand-held pagers, etc., through which it is possible to judge whether the elderly Fall, and can send out an alarm at the first time to remind the elderly and the people around them, ...

AI Technical Summary

Problems solved by technology

The video-based detection system has the characteristics of not needing to wear, but there are problems such as limited detection range, large amount of data, complex equipment, and high algorithm complexity.

The acoustic-based fall detection system realizes fall detection by analyzing the audio signal when it falls. It does not need to be worn, but it has the disadvantages of high environmental requirements and low precision.
