Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0038] Such as figure 1 As shown, the ZigBee-based elderly chair fall alarm system includes the perception layer, network layer and application layer.

[0039] The perception layer uses the ZigBee network to collect the data of the state of the chair for the elderly, and is responsible for the fall detection. ZigBee is a wireless network protocol for low-speed and short-distance transmission. The bottom layer is the media access layer and physical layer that adopt the IEEE802.15.4 standard specification. The main features are low speed, low power consumption, low cost, support for a large number of network nodes and multiple network topologies, low complexity, fast, re...

Abstract

The invention discloses an old people on-chair falling alarming system based on Zigbee. The old people on-chair falling alarming system comprises a sensing layer, a network layer and an application layer, wherein the sensing layer adopts a ZigBee network to detect the old people on-chair state data, and is used for detecting falling, and the network layer is used for receiving the data of the sensing layer, and sending the alarming information to the application layer. By adopting the technical scheme, the old people on-chair falling alarming system based on ZigBee has the advantages that the data of a pressure sensor and a temperature sensor are collected by a ZigBee sensing network technology, and are analyzed by an adaptive weighted data integration algorithm to obtain integration results, and the integration results are uploaded to an upper computer through a ZigBee-WiFi gateway, so as to judge whether the old people stays on a chair or a bed; when the judging result shows that the old people falls down, the alarming information is immediately sent to family members or medical organization terminals through a GSM (global system for mobile communications) network and an Internet network; the falling alarming information is timely sent to workers and the family members by various methods, so the old people falling accident can be timely found and examined, and the emergency rescue measure is taken; the potential research value and realistic application meaning are realized.

Description

technical field [0001] The invention belongs to the field of wireless sensor networks, in particular to a ZigBee-based fall alarm system for the elderly on a chair. Background technique [0002] In today's society, the aging of the world's population is accelerating, and the number of people with disabilities caused by various diseases and disasters is also increasing year by year. In addition, the modern young labor population is flowing, the working area is expanding, and the elderly live separately from their children. The function of family care for the elderly has been lost, and the phenomenon of "empty-nest elderly" has appeared, which makes the aging problem "worse". According to statistics, among the 185 million elderly people over the age of 60 in China, "empty nest elderly" account for half of them, and most of their health and safety issues do not receive effective and timely attention. At the same time, the number of elderly people in nursing homes has risen sha...
