Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. figure 1 Shown is a specific flow chart of an elderly fall detection method based on a triaxial sensor and an ECG sensor, and the detection method includes the following steps:

[0032] 1) Use the ECG sensor to collect ECG sample data with fall stress response and normal daily behavioral activities;

[0033] 2) Preprocessing the sample data;

[0034] 3) Extract the characteristics of the sample;

[0035] 4) Train the classifier with the features of the sample;

[0036] 5) Real-time collection of data from triaxial sensors and ECG sensors;

[0037] 6) Preprocess and calculate the acceleration change rate and peak value of the three-axis sensor in real time and judge whether it exceeds the threshold. If it exceeds, the next step is to judge, otherwise it is judged that it has not fallen;

[0038] 7) Extract the ECG data cached in the ECG sensor for 10...

Abstract

Provided are a fall detection method and a fall detection system for old man based on a three-axis sensor and an electrocardiograph sensor. The detection method comprises: 1) using the electrocardiograph sensor to acquire electrocardio sample data which has falling stress reaction and daily actions and activities under normal conditions; 2) preprocessing the sample data; 3) extracting features ofthe sample; 4) using the features of the sample, training a classifier; 5) acquiring data of the three-axis sensor and the electrocardiograph sensor in real time.

Description

technical field [0001] The invention relates to the fields of medical health, signal processing, machine learning, etc., and in particular to an elderly fall detection method and detection system based on a three-axis sensor and an electrocardiogram sensor. Background technique [0002] According to statistics, my country entered the aging society at the end of the 20th century, and it is expected that by 2050, it will enter the stage of deep aging and become the most aging country. This will also bring huge pressure and challenges to our society from many aspects. Under such circumstances, the needs of the elderly for life care and travel are becoming increasingly prominent, which is particularly reflected in the issue of safety and health care, mainly reflected in the following two points: First, the physical function of the elderly is degraded, and they are extremely prone to accidents or illnesses. (especially cardiovascular and cerebrovascular diseases) falls. Accordin...
