Method and device for monitoring human tumbling

Abstract

The invention discloses a method and a device for monitoring human tumbling. The method includes steps of acquiring information of various postures of a human by a three-axis acceleration sensor module, an ultrasonic distance measuring module and foot sole pressure sensors on a human body; judging whether the human tumbles or not according to the posture information of the human; transmitting the information of human tumbling to the outside through the network. The method and the device for monitoring human tumbling can accurately judge the tumbling information and avoid mistaken judgment, tumbling position information is transmitted to the outside, the tumbling human is rescued in time, and various defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of electronic monitoring, in particular to a method and device for monitoring human falls. Background technique [0002] With the progress of society and the development of science and technology, the extension of the average life expectancy of human beings has led to an increasing population of elderly people, and population aging has become a worldwide problem. The health and care issues of the elderly are widely concerned by people, especially the alarm and timely rescue of the elderly after they fall naturally come to the fore. [0003] At present, in terms of monitoring and alarm technology for human falls, there are mainly: [0004] 1. Based on video image monitoring technology, the characteristics are: the real-time movement of the object is monitored by the camera, and the use of image processing technology can accurately and effectively distinguish human body postures such as walking, squatting, an...

AI Technical Summary

Problems solved by technology

The disadvantages are: the user's privacy cannot be guaranteed, the scope of application is limited, it can only be used indoors or in a small area, it is greatly affected by light, and the misjudgment rate is high

The disadvantage is that the misjudgment rate is greatly affected by the surrounding external sound, the interference is very serious, resulting in an increase in the misjudgment rate, and, compared with the previous technology, it is difficult to judge the relative posture of the human body

The disadvantage is that the user must be active in an environment that can be detected by the infrared sensor before the system can perform fall detection on it. It also has a limited scope of application and cannot be carried around. It can only be used or monitored in a small area where the device is installed; Moreover, based on infrared technology, it is difficult to distinguish the identity of the monitored object. Due to the influence of other human or animal infrared sources, the misjudgment rate remains high.

The disadvantage is: the human body data information collected by a single sensor is relatively single, and cannot fully reflect the posture information of the human body, which is relatively one-sided, resulting in a high rate of misjudgment
