Description

Remote medical system

Technical Field

The invention relates to the technical field of health management and human body detection, in particular to a remote medical system.

Background

The human body detection technology is widely applied to the fields of security protection, automatic driving and intelligent home, wherein the most common human body detection technology is an infrared induction technology. The active infrared detector judges whether a human body exists or not by judging whether the infrared signal between the infrared transmitter and the infrared receiver is shielded or not, and has the advantages of high sensitivity and simple implementation scheme, and the defects that the shielding of any object on the infrared signal can be triggered and whether the human body exists or not can not be identified. The passive infrared detector judges whether a human body exists or not by detecting infrared rays emitted by the human body, and can accurately identify the difference between the human body and a non-human body due to the fact that the temperature range of the human body corresponds to a certain infrared energy, but the passive infrared detector is poor in sensitivity, easy to be influenced by the ambient temperature and low in reliability. Both the active infrared detector and the passive infrared detector have the problems of short detection distance and easy shielding. In recent years, a microwave human body detection technology is researched, a moving object can be detected by detecting emitted microwaves, the microwave detection has the characteristics of high detection precision, large detectable distance and small shielding influence, the detection on human body micro-motion characteristics such as respiration and heartbeat can be realized, however, the microwave human body detection is easily interfered due to overhigh sensitivity, and the slight vibration of peripheral objects can cause false alarm, so that the accuracy of human body detection is reduced.

The old people have poor physical balance ability, fragile bones and easy falling, the falling in a toilet accounts for more total falling of the old people, and many old people fall in the toilet every year. The toilet in the house is the place where the elderly are most prone to accidents: the falling-over risk can exist at any moment due to the fact that people kick the threshold and trip, the ground is slippery and slippery, people sit for a long time in a toilet, crouch for a long time and get up for a long time and fall down, people have a bath and stand for a long time, the gravity center is unstable, people can fall down, and the like. The intelligent wrist-watch that appears in the market, wearing equipment such as intelligent bracelet have the detection function of tumbleing, wear the wrist watch in user's wrist and wave, activity such as swing by a wide margin along with the wrist, but because the great activity of impact force probably with tumble very similar, can not detect the accuracy. In the technical scheme, although the video method can realize detection, the privacy problem exists.
