Wearable old people falling detection method and device

Abstract

The invention discloses a wearable old people falling detection method and device. The method comprises the following steps of: 1, detecting the motion state information of a human body through a three-axis acceleration sensor so as to judge whether an old people has a non-falling behavior or not; 2, judging the height change of the human body through a barometer, and combining an accelerometer tojudge whether the human body has a falling-like behavior or not; and 3, judging whether the human body has a falling behavior or not through an attitude angle detected by a nine-axis sensor and a human body height detected by the barometer. The wearable falling detection device comprises a sensor module, a controller, a positioning module, an alarm module and a wireless communication module. Through the sensor module, the states of old people are detected; and when abnormal conditions occur, the abnormal conditions can be positioned, and alarm is carried out to notify the guardians, so that the old people can be treated and cured in time so as to avoid other secondary injures.

Description

technical field [0001] The invention relates to the field of elderly care and the field of electronic equipment, and in particular to a wearable method and device for detecting and alarming the fall of the elderly. Background technique [0002] All countries in the world, especially developing countries, are facing a common issue: population aging. As of the end of 2018, my country's population aged 60 and over was 249 million, accounting for 17.9% of the total population, of which the population aged 65 and over was about 167 million, accounting for 11.9% of the total population. It is generally believed that the number of elderly people aged 60 and above accounts for 10% of the total population, which means entering an aging society. my country has entered an aging society from 1999 to 2018, with a net increase of nearly 200 million elderly population. In the past three years, an average of 9 million new elderly people have been added every year, of which the new elderly...
