An Indoor Monitoring System for Empty Nest Elderly

Abstract

The invention discloses an indoor monitoring system for an empty-nested elderly person, which comprises an environment monitoring module, a fall pre-analysis module, a ZigBee network module, a home gateway and a GSM module, wherein the fall pre-analysis module comprises a pressure sensor attached to the foot of the elderly person, an acceleration sensor attached to the waist and a central microprocessor connected with the output end of the acceleration sensor; the ZigBee network module comprises a ZigBee coordinator and a ZigBee terminal; the environment monitoring module and the fall pre-analysis module are connected with the input end of the ZigBee terminal; the home gateway judges whether a hidden risk exists in the current living environment of the elderly person through analysis by an information fusion algorithm; and the GSM module is used for information notification for family members of the elderly person. The monitored data precision can be improved, fault and environment interference are avoided, the family members can be timely informed according to the judged risks, and a polling cycle can be dynamically corrected according to the judged risk degree.

Description

technical field [0001] The invention relates to an indoor monitoring system for empty-nest elderly, and belongs to the technical field of indoor monitoring systems. Background technique [0002] Nowadays, with the rapid development of the Internet of Things, the concept of smart home is gradually integrated into our daily life, becoming an increasingly hot topic in the industry, and also an important trend in our future life. The indoor environment monitoring system is a specific application of smart homes. It uses advanced wireless sensor networks to organically integrate various sensor nodes scattered in the room, and collects and analyzes data through the home gateway controller. The data can be saved. Local or upload to the cloud for further regional management. On the other hand, from a social perspective, with the deepening of the aging society, the proportion of empty-nest elderly is also increasing, and the safety of living alone and empty-nest elderly has gradually...

AI Technical Summary

Problems solved by technology

[0004] 1) In addition to the data acquisition module, the complete set of monitoring systems that are common on the market also includes a video monitoring module and a glass door and window anti-theft module. easy to maintain

[0005] 2) The safety is not good, the ordinary monitoring system only takes into account the objective environmental factors, such as temperature, humidity, gas concentration

These monitoring parameters are applicable to ordinary families, but considering the special circumstances of empty-nesters, for example, they cannot be applied to special situations such as bathroom fall monitoring

[0006] 3) Most environmental monitoring systems on the market only monitor the environment by setting a threshold, ignoring the interrelationship of a network system. It is easy to misjudge many potential threats only through threshold analysis, and it is not properly used as a family The data analysis capability of the gateway's microprocessor

[0007] In summary, the existing indoor environment monitoring systems are not well targeted, have redundant functions, and are complicated to implement and install.
