Abstract

The invention discloses a falling-down detection device and method. The falling-down detection device comprises a sensor, a microcontroller, an alarm, a positioning communication module and a help communication module, wherein the sensor is used for measuring acceleration and angular speed original data of a human body during moving and processing the acceleration and angular speed original data to obtain a gesture value, the microcontroller is used for evaluating and screening motion characteristic of acceleration data, distinguishing falling-down behavior and other daily activities, trainingand testing an acquired sample, processing a falling-down result according to a detected falling-down signal, giving a warning signal to the alarm if the falling-down signal is detected, continuing to send a detection instruction to the sensor if the warning signal is interrupted, sending a communication instruction to the positioning communication module if the warning signal is not interruptedand simultaneously sending a help instruction to the help communication module, the failing-down and normal activities similar to falling-down are accurately distinguished, timely help information canbe sent out, and remote monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of human body wearable devices, in particular to a fall detection device and method. Background technique [0002] The biggest accidental injury and disease trouble for the elderly in daily life comes from falls. The prevention of falls, the detection of falls, the timely alarm, and the protection of falls have become research hotspots in recent years. The device of the existing fall detection device is heavy and complicated, the cost is high, it is not easy to carry, and the pre-alarm is not timely. [0003] Existing fall detection generally uses an accelerometer to obtain body acceleration data, detects and judges whether a fall has occurred, and rarely considers changes in human body posture in the process of judging a fall. Contents of the invention [0004] In order to solve the problems of the prior art, the present invention provides a fall detection device and method, the device relates to the fun...
