Problems solved by technology

However, due to the complexity of the daily behavior of the human body, the situation or sound in the actual application environment will cause different degrees of misjudgment in the detection of falls; on the other hand, the application of high-definition video or audio equipment is very limited. It is expensive, bulky, and limited in application occasions, and cannot accurately identify and warn the fall behavior of the elderly in real time
[0004] At present, there are many brands of smart bracelets on the market, which are used for daily step counting, but their functions are single, and they must be used in conjunction with a mobile phone when viewing the step counting results, and it is impossible to observe the step count results in real time at a glance

Abstract

The invention discloses a smart band detecting falling down. A sensing unit, a processing unit, a communication unit and a data storage unit are arranged in a smart band shell body. The smart band is characterized in that the sensing unit comprises a three-axis accelerating sensor and a double-axis angular-speed sensor; the data storage unit can record original data collected by the sensing unit; the processing unit can receive and processing data collected by the sensing unit; and the communication data can send the data processed by the processing unit to a cloud server. The smart band detecting falling down has high precision and long service life, and is helpful for healthy life of the old.

Description

technical field [0001] The invention relates to the field of sensor detection, in particular to an intelligent wristband for detecting falls. Background technique [0002] Falling is a serious threat to the health and life of the elderly, and it also brings a heavy burden to society. In my country, falls are the leading cause of injury death among the elderly over 65 years old. How to obtain the kinematic data of human fall behavior, accurately identify it and give timely warning is of great significance to reduce the injury caused by falls in the elderly. [0003] At present, the automatic detection methods for falls of the elderly mainly include video detection, or audio and vibration recognition. However, due to the complexity of the daily behavior of the human body, the situation or sound in the actual application environment will cause different degrees of misjudgment in the detection of falls; on the other hand, the application of high-definition video or audio equip...
