Indoor positioning-based detection method and system for falls and sudden heartbeat bracelets

Abstract

The invention discloses a method and a system for detecting falls and sudden changes of heartbeat based on indoor positioning, and belongs to the technical field of family personnel monitoring. First, establish a wristband detection system, install a plurality of indoor base stations, and the guardian wears the wristband; the guardian's mobile phone APP; the detection method includes the following steps: the wristband sends the guardian's status message to the base station with a default period, and the base station receives the message. Then send the message to the public network server; after receiving the message from the base station, the public network server records the location and time information, deletes outdated and invalid data, and analyzes the heart rate and fall information at the same time; the public network server collects the analyzed emergency data It will be pushed to the guardian's mobile APP, and the guardian's mobile APP can also query the activity track of the ward at home. The public network server of the present invention analyzes according to the uploaded historical data, and combines the heartbeat mutation data to determine whether the ward really falls, so as to minimize the misjudgment rate.

Description

technical field [0001] The invention relates to the technical field of family personnel monitoring, in particular to a method and system for detecting falls and sudden heartbeat bracelets based on indoor positioning. Background technique [0002] With the improvement of the quality of life, the average life expectancy of human beings has also increased compared with the past, and the number of elderly people has also increased. According to relevant statistics, nearly 100 countries around the world have entered the aging society, that is, they are 65 years old and above The number of elderly people accounts for more than 7% of the total population of the country. [0003] The elderly are frail and sick, and have limited mobility, especially for the elderly with Alzheimer's disease, or other people with mental disabilities due to various reasons, there may be many risks if no one is around to take care of them, such as heart attack, high blood pressure, falls and fractures W...

AI Technical Summary

Problems solved by technology

[0004] At present, there are related devices for monitoring the falls of the elderly, such as mobile phone APPs placed in the chest pocket, wearable devices tied to the waist, thighs, etc. Some devices also have the function of detecting heartbeats. This type of device detects that the human body is tilted to a certain extent. To judge falls, the accuracy is high, but wearing equipment brings a lot of inconvenience to the daily life of the elderly (moving, sleeping, bathing). When it brings discomfort to people, the elderly / mentally disabled may refuse to wear it or try their best Take it off and may not have the ability to put it back on by yourself

In addition, this kind of equipment consumes a lot of power, and frequent charging is not within the ability of this kind of people

[0005] In order to solve the above problems, the fall detection function and the heartbeat detection function have been transplanted to the bracelet, and the fall detection results are uploaded to the public network server through the Sim card on the bracelet. This solution brings convenience to the elderly / mentally disabled. , but due to the flexibility of the arm movement, the misjudgment rate is high and the practicability is poor; secondly, the defect of relatively large power consumption for SIM card communication still exists
