WIFI-based elderly home remote monitoring system

Abstract

The invention discloses a WIFI-based elderly home remote monitoring system. The system comprises a WIFI network, a master control terminal module and a remote monitoring center. The WIFI network comprises a wireless access point and a terminal node, the wireless access point and the terminal node adopt an LWIP protocol for networking, when the terminal node is connected, the wireless access point performs SSID and password matching on the terminal node, and TCP connection is established after successful matching; the terminal node transmits the acquired environment data to the wireless access point; the main control terminal module acquires the environment data from the wireless access point, and is also responsible for detecting whether the old people fall down or not, and sending the environment data and fall detection information to the remote monitoring center; and the remote monitoring center stores the received data in a local database, and can perform operations such as addition, deletion, modification, checking and display on the data. According to the invention, real-time monitoring of the living environment and the falling behavior of the elderly can be realized, and when the environment data is abnormal or the falling condition occurs, countermeasures can be taken in time.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, and specifically designs a WIFI-based home remote monitoring system for the elderly. Background technique [0002] The arrival of an aging society will inevitably bring many social problems and challenges, and the traditional way of providing for the elderly cannot meet the effective needs of the elderly. As the application fields of Internet of Things technology become more and more extensive, it has shown important value in smart home, industrial control, smart medical care and other aspects. Technology-supported smart elderly care optimizes and integrates the allocation of elderly care service resources, improves the efficiency of elderly care services, and revitalizes the traditional elderly care model. For example, when the elderly go out for a walk or shopping in daily life, they should consider whether the outdoor air quality is convenient for travel. In daily activities, ...

Problems solved by technology

For example, some use a single controller to connect multiple environmental data acquisition sensors. In this way, the lack of pertinence for environmental monitoring data leads to a decrease in accuracy. If multiple acquisition nodes are arranged in this mode, the cost of system implementation will be increased.

It also ignores the data error caused by the sensor itself affected by the environmental noise when collecting data

When transmitting data, most of them use the WIFI module to transmit the data to the mobile phone or the routing device to transmit the data to the cloud server for viewing on the mobile phone, which will limit the transmission distance and increase the cost

In terms of fall detection, most of them use a single threshold detection and ignore the interference of environmental noise when the hardware itself collects data. Both of these situations will increase the probability of misjudgment and greatly reduce the efficiency of detection.
