Overview
The main service targets of nursing homes are the elderly, and the problem of aging is more prominent. Because of their older age, the elderly are more or less physically inconvenient, and the degree of self-care is not as good as that of the young, and they are more prone to accidents. The infrastructure construction in nursing homes is becoming more advanced, and they are generally equipped with gardens, fitness venues, entertainment venues, and leisure venues. These facilities first enrich the lives of the elderly and add luster to the lives of the elderly; at the same time, they also bring potential inconveniences to the elderly. Because the site involves a large area, it is impossible for the management personnel to take care of every elderly person in each location. When an elderly person has a problem, it is necessary for the service personnel to find the location of the elderly person and provide corresponding assistance as quickly as possible. Therefore, it is necessary to adopt an effective way to take care of the elderly, and to determine the location of the elderly in the nursing home in real time and provide timely services to them. “Positioning” is even more important.
The safety problems caused by strangers entering the nursing home cannot be ignored. A technical method is needed to assist in realizing information about the activities of the strangers in the park to ensure the safety of the park. This system adds the card binding function of outsiders, which facilitates the management of the park.
1. System introduction
2-1 Summary
This system consists of a hardware system and an application software system. The hardware system uses our company’s latest 125K+433M high-precision positioning technology. Compared with the traditional 2.4G technology, it has a large range and weak margins. It can realize a single locator 1-5 The radius of meters and the marginal accuracy of 30cm can clearly distinguish the location of the personnel, which room the old man is in, which staircase, and even which corner is at a glance. The software system combines the characteristics of the daily safety management of nursing homes, and has designed functional modules such as personnel positioning management, night patrols, and rounds before going to bed to facilitate the management of multi-task management for the elderly in the whole time period.

2-2 Hardware System
The hardware system consists of four parts:
Trigger locator, network card reader integrated machine, 485 controller, personnel positioning card/wristband card.
GPS:
The effective communication range of the locator has a radius of 0~5m, which can be adjusted continuously through the knob. Usually the card is in a semi-dormant state. When a person wears the positioning card and passes through a certain locator coverage area, the card is activated, and the card sends the locator position information and card number information to the network card reader, and then the network card reader machine It is transmitted to the 485 controller through the 485 line, and uploaded from the controller to the management center PC, and the position information and related applications of each card are displayed in real time through the software.
Networking mode:
As shown in the above figure, except for the 485 wired connection between the network card reader integrated machines, the other devices can be connected by wireless ad hoc network. Generally, in a multi-storey high-rise building, a network card reader integrated machine is installed on each floor. The network card reader integrated machine between floors is connected by 485 bus, and the equipment on each floor is connected by 485 bus.
2-3 Advantages of hardware products
(1) Precise positioning: The hardware of this system adopts the latest low-frequency wake-up trigger + high-frequency communication technology, and the positioner can achieve a boundary accuracy error within ±30cm.
(2) Wireless ad hoc network: The wireless ad hoc network transmission method is adopted between the hardware device trigger and the network card reader integrated machine, and there is no need to lay any weak current cables during construction.
(3) Wristband design with button alarm function: A wristband card specially designed for the elderly, with a button design, backlight display, comfortable to wear, the elderly can ask for help through the buttons.
(4) Long service life: Through the refined design of the card, the normal battery life of the card can be as long as 1.5 years.
(5) The battery is easy to replace: the snap-on battery compartment design makes it easy to replace.
(6) Low-voltage alarm: When the card battery is low, the software system will automatically prompt a low-voltage alarm.
