Piezoelectric film based falling and heart rate monitoring and automatic help system

Abstract

The invention provides a piezoelectric film based falling and heart rate monitoring and automatic help system. The system accurately judges whether or not old people fall down by a PVDF (polyvinylidene fluoride) sole pressure sensor and PVDF pulse sensor based and combined judgment method, and monitors the heart rate in real time at the same time. By selection of working modes, convenience is brought to the old people for selecting various appropriate working modes at different moments. When the old people fall down or are in emergencies such as abnormal heart rate, the old people can be positioned, and short messages are sent to children, hospitals, community security guards and the like so as to allow the old people to obtain rescue in time. A temperature and humidity sensor is mounted on a multifunctional wristwatch, ambient temperature and humidity are collected and displayed on an LCD (liquid crystal display), the old people can obtain ambient data when locking at the watch for time, and convenience is brought to the old people for going out.

Description

technical field [0001] The invention relates to a fall and heart rate monitoring and automatic rescue system based on a piezoelectric film, which is characterized in that when the old man falls and has an abnormal heart rate, it can accurately locate the position of the old man, automatically send a short message for help, and has the ability to measure the temperature and humidity of the surrounding environment function. Background technique [0002] With the development of social economy and cultural progress, people pay more and more attention to the health and protection of the elderly. Although some elderly people now wear mobile phones, it is necessary for some emergencies such as fainting after falling down and unstable heart rate at night. Unable to contact family members in time and ask for help. At the same time, modern people are concerned about whether to help the elderly after they fall.

[0002] With the development of social economy and cultural progress, people pay more and more attention to the health and protection of the elderly. Although some elderly people now wear mobile phones, it is necessary for some emergencies such as fainting after falling down and unstable heart rate at night. Unable to contact family members in time and ask for help

At the same time, modern people are concerned about whether to help the elderly after they fall. When the elderly fall or have other conditions, the risk is greatly increased because they cannot get timely rescue.

Although there are some devices for monitoring whether the elderly have fallen, they are only judged by a single detection method, and cannot accurately judge the status of the elderly, and have a single function. Therefore, although the function can be realized, it cannot be highly efficient.
