Description

A system and method for home-based elderly care monitoring

technical field

The invention relates to a home care monitoring system and method, in particular to a home care monitoring system and method for wireless sensor monitoring of various vital signs of the elderly.

Background technique

Due to the improvement of people's quality of life and the continuous improvement of the average life expectancy, China is currently entering an aging society. According to data released by the National Bureau of Statistics, by the end of 2014, the elderly over 60 years old accounted for 15.5% of the total population in China, reaching 212 million. And there is a trend of continued growth. This makes the pension problem more and more serious. The more traditional old-age service institutions in the current society are generally nursing homes. Although this reduces the pressure on children to support them, it cannot meet the demands of the spiritual world of the elderly. According to the survey of the World Health Organization, home care for the elderly can be integrated with the surrounding environment, continue the previous social network, and make the elderly's mental health healthier. In order to ensure the physical and mental health and personal safety of the elderly, the development of intelligent elderly care monitoring system technology in recent years can not only meet the needs of the elderly for their homes, but also meet the needs of their children for the safety and health of the elderly.

The old-age monitoring system in the existing technology mostly uses wearable devices such as wrist watches and smart cards and cameras to collect the vital signs of the elderly, upload video and image information to the remote data platform and perform related data processing. The problems in the monitoring system based on this scheme are: wearable devices cause inconvenience to the life of the elderly, and the uninterrupted camera monitoring method violates the privacy of the elderly.

Chinese patent CN204614152U discloses an intelligent home care system based on the Internet of Things, including GPS positioning system, remote video monitoring system, voice transmission system, acceleration sensor, intelligent security system and other modules to realize intelligent management of elderly care. However, this patent has many deficiencies: for example, the GPS positioning system used is inaccurate when it is specific to the room; the remote video monitoring is not authorized, and it is easy to violate the privacy of the elderly; a large amount of data uploaded to the remote data platform cannot be carefully obtained. treatment without the participation of professional medical staff.

Chinese patent CN204445857U discloses a remote monitoring system for home rehabilitation, including RFID tags, vital signs monitoring devices, infusion monitoring devices, medication reminder devices, monitoring base stations, warning units, home feedback terminals and hospital feedback terminals; The infusion status and medication status are monitored in real time, and after being processed by the monitoring base station, they are fed back to the home feedback terminal and the hospital feedback terminal. However, a technical solution of this patent discloses the use of a GPS locator, but when the GPS is specific indoors, due to signal and other reasons, it cannot accurately locate; in addition, the interaction between the system and the elderly, guardians, and relatives is also poor. .
