Falling alarm device and method based on pressure and accelerated speed detection

Abstract

The invention discloses a falling alarm device based on pressure and accelerated speed detection. The falling alarm device based on pressure and accelerated speed detection comprises a wrist watch shell body, a peripheral connecting three-axis acceleration sensor, an OLED screen, a GPS positioning module, a Bluetooth 4.0 host module and a buzzer, wherein the peripheral connecting three-axis acceleration sensor is arranged in a wrist watch, and a central processing unit STM32 serves the core of the peripheral connecting three-axis acceleration sensor. The invention further discloses a falling alarm method based on pressure and accelerated speed detection. The falling alarm method based on pressure and accelerated speed detection comprises the following steps that 1, the change of the pressure value, acquired by a pressure sensor, of a person is detected by a processor, and a signal is sent to a receiving module of the wrist watch through a wireless transmitting module when the change of the pressure value reaches a set threshold value; 2, the change of the angle of the wrist is obtained by processing data acquired by the three-axis acceleration sensor through the central processing unit of the wrist watch, whether the change meets a specific law is judged, and an alarm is given immediately when it is judged that a person falls. The falling alarm device and method based on pressure and accelerated speed detection have the advantages that safety and reliability are high, and the alarm method is user-friendly.

Description

technical field [0001] The invention relates to a fall positioning alarm and remote monitoring technology, in particular to a fall alarm device based on pressure and acceleration detection and a method thereof, belonging to the field of safety protection. Background technique [0002] With the rapid and stable development of the national economy and the remarkable improvement of people's living standards, my country has gradually entered the era of declining birthrate and aging population. The aging of the population will soon become an unprecedented new challenge that China is facing. The outstanding problem brought about by aging and declining birth rate is that as the elderly age increases and their self-care ability declines, when the elderly encounter unknown dangers, they are prone to various accidents due to failure to deal with them in time to a large extent. Accidents, thereby endangering the personal safety of the elderly. In these accidents, the accidents caused ...
