Abstract

The invention discloses a big data based old people tumble detection method and system in real environments, and belongs to the technical field of pattern recognition and human behavior recognition. The technical problems that conventional tumble detection systems and methods have low accuracy, cannot meet individual differences and obtain old people tumble experiment data can be solved. The adopted technical scheme is as follows: 1) the method is based on a big data platform, and constructs the old people tumble detection system in real environments by utilizing wearable equipment and an Internet of Things technology; the daily behavior data of the old people in the real environments can be collected through the wearable equipment; and the data can be sent to the big data platform throughthe Internet of Things technology; and 2) the system includes the wearable equipment, peripheral alarm equipment and the big data platform; and the wearable equipment includes a sensor, a single-chipmicrocomputer and a wireless transmission module.

Description

technical field [0001] The invention relates to the technical field of pattern recognition and human behavior recognition, in particular to a method and system for detecting falls of the elderly in a real environment based on big data. Background technique [0002] Fall detection systems based on wearable devices are generally worn on the chest, waist, legs, and wrists. By adding relevant posture sensors to the device, a wearable detection device is formed, and the data output by the sensor during the movement of the subject is collected to analyze and detect the fall behavior. Another advantage of the wearable device is that it can collect physiological indicators, such as blood pressure and ECG, which cannot be collected by other video or environment-based fall detection systems. Shang-Lin Hsieh of Tatung University et al. proposed a wrist-type fall detection system. Through experiments, it was found that the system obtained good average sensitivity and specificity. Pann...
