Problems solved by technology

[0003] In the process of home care for the elderly, although there are human sensors and other equipment in the elderly’s home, it is impossible to intuitively judge the trajectory of the elderly throughout the day. The trajectory of the elderly can only be estimated by the time of passing a certain monitoring point. Although the camera can solve the problem This problem, but the privacy data collected by the camera will be disturbing, and the equipment cost is high
Beacon positioning is to use Bluetooth broadcast technology to detect the signal strength of surrounding beacons, and then use three-point positioning to calculate the position of the beacon, but its disadvantage is that it is only relatively accurate within a radius of 10 meters, and there will be a large error if it exceeds

Abstract

The invention discloses a home elder positioning system based on a wireless positioning technology. The home elder positioning system comprises a wearable positioning device, a network router and at least one positioning assembly. Each set of positioning assembly comprises a wireless infrared human sensor and three wireless positioning nodes; the wearable positioning device, each wireless infrared human sensor and each wireless positioning node are in wireless networking communication through a Zigbee module; the wearable positioning device comprises an elastic band and a strip-shaped shell. And a microprocessor, a memory, a power supply module and an acceleration sensor are arranged in the strip-shaped shell. According to the home elderly positioning system based on the wireless positioning technology, the wearable positioning device and the three wireless positioning nodes are used for wireless networking communication, communication data can be transmitted, the relative position of the wearable positioning device in a positioning interval can be determined through three-point positioning, the real-time tracking of the movement track of the elderly is achieved, life, exercise and safety of the elderly are supervised, and guarantee is provided for the home-based care of the elderly.

Description

technical field [0001] The invention relates to an indoor positioning system, in particular to a positioning system for the elderly at home based on wireless positioning technology. Background technique [0002] With the widespread popularization of Internet of Things technology, because ordinary WiFi routers can only connect about 20 devices at most, and as people are more and more interested in the number and types of devices, and the power consumption of WiFi direct-connected devices is extremely high, in some When the mains power cannot be connected, the form of WiFi direct connection cannot be used, so people are no longer satisfied with the devices of WiFi direct connection. ZigBee is a wireless network protocol for low-speed short-distance transmission. Although the data bandwidth is very limited, its power consumption is low. [0003] In the process of home care for the elderly, although there are human sensors and other equipment in the elderly’s home, it is imposs...
