Problems solved by technology

[0005] 1) The fall detection method based on the image video sensor has a small monitoring range and needs to install one or more cameras in the surrounding environment. The detection cost is high, and it is easily affected by environmental factors such as light. The detection range is also limited to fixed hospitals, In certain occasions such as nursing homes, monitoring is not effective for outdoor activities, so when the elderly fall down, they cannot be found in time and cause serious consequences
[0006] 2) The wearable detection signal factor is single, and has a great relationship with the wearing position. If the wearing position is correct, there will be a large error in the detection result
[0007] 3) The pressure sensor suitable for wearing on the sole of the foot has a lot to do with the distribution of the sensor. If the distribution is improper, the signal acquisition of the sole of the foot will be inaccurate, which will cause misjudgment
[0008] 4) Most of the above detection methods are still limited to local or PC-side processing, mainly scientific research, lack of mobile client access and cloud service platforms for health management, and there is still a certain gap between actual fall detection and health management applications

Abstract

The invention relates to a human behavior analysis cloud management system based on multi-sensor data fusion, belonging to the technical field of sensors. The system comprises: a plantar pressure detection subsystem, an image video detection subsystem, a human posture detection subsystem, and a blood pressure and pulse detection watch. The system includes a plantar pressure detection subsystem fordetecting plantar pressure parameters in real time, a posture detection subsystem for detecting a human posture through an accelerometer gyroscope and a geomagnetic sensor, a video subsystem for obtaining a human horizontal inclination angle image, and a smart watch for detecting physiological data of the human body. The data is wirelessly transmitted to the user terminal, and the user terminal judges the fall of the data, generates the fall information when the user falls, and sends the current position of the user and the fall information to the preset guardian mobile terminal, thereby realizing remote monitoring of the fall and fainting of the user.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a human behavior analysis cloud management system based on multi-sensor data fusion. Background technique [0002] With the deepening of the aging degree, it is imperative to establish health records for the elderly. Among them, for the elderly, the prevention of falls and the alarm after a fall have become important issues that the society has to study and solve. Statistics show that 20% of the fall patients who are hospitalized are caused by not being rescued in time due to reasons such as being undetected for a long time after the fall. The prevention and alarm of falls of the elderly has received extensive attention in the fields of medical care, health care, and behavior recognition. [0003] At present, fall detection technologies mainly include: wearable fall detection systems, which are generally worn on fixed parts of the human body, such as the waist, chest, wrist and ot...
