Indoor elderly people monitoring method and system based on Internet of Things

Abstract

The invention discloses an indoor elderly people monitoring method and a system based on Internet of Things. The method comprises the following steps: S1, a blind node detects motion information of the elderly people by using a three-axis acceleration sensor, and gesture of the elderly people is judged according to the motion information and pressure data provided by a pressure node; S2, the blind node broadcasts positioning request data packets to surrounding reference nodes, and the respective reference nodes extract and package the receiving signal strength values in the positioning request data packets and send the receiving signal strength values to an embedded gateway; and S3, the embedded gateway calculates location of the elderly people and displays the location and the gesture of the elderly people on a display screen of the embedded gateway in real time. When the indoor elderly people monitoring method is adopted, safety of the elderly people can be monitored in real time, and individual privacies of the old are well protected, so that the elderly people are easy to accept the method. In addition, as the indoor elderly people monitoring system is based on the Internet of Things and does not need indoor wiring, original indoor layout cannot be disordered, and wiring cost can also be saved for a user.

Description

technical field [0001] The invention relates to an indoor monitoring method and system for the elderly based on the Internet of Things, and belongs to the field of information technology of the Internet of Things. Background technique [0002] Population aging is a global problem, and the current situation of aging in my country is particularly severe. Therefore, how to realize the safety monitoring of the elderly has become a hot topic and focus of discussion. The safety monitoring mentioned here especially monitors the accidental falls of the elderly, so that It can be realized that the elderly can be rescued in time after they accidentally fall, and the probability of accidents can be greatly reduced. The existing elderly monitoring system uses an acceleration sensor (single-axis or biaxial acceleration sensor) to detect whether the elderly has fallen and uses video equipment to monitor other postures of the elderly such as sitting, standing, walking and lying.

Problems solved by technology

[0003] However, the use of video equipment to monitor and record the behavior of the elderly is easy to violate the privacy of the elderly, making it difficult for the elderly to accept psychologically; in addition, the existing monitoring system for the elderly needs indoor wiring, which will not only damage the original layout, but also adds additional routing overhead
