Abstract
Abstract With the gradual ageing of China's population and the single-child family system becoming the backbone of society, the traditional pension way of relying on children at home not only does not guarantee the quality of life of the elderly, but also brings great pressure to the work and life of young people. The way of relying on pension institutions to provide for the aged is becoming gradually accepted by society. In elderly care institutions, safety supervision systems provide an important link to protect the safety of the elderly, thereby ensuring accurate analysis and supervision of the elderly persons’ activity routes and activity rules, and thus allowing an early warning to be given in a dangerous situation. The system realises the real-time positioning and monitoring of the elderly activity track, and can give early warning and timely rescue to the elderly who enter into any dangerous area. The system includes a server monitoring program and mobile APP; ASP.NET Technology to develop the monitoring program; SQL Server 2012 for data storage; and model view controller (MVC) architecture for the APP to improve the efficiency of program development. The supervision program comprises the functions of personnel information management, fence management, positioning service, activity track record, danger warning and rapid rescue. The APP deploys the location-based service (LBS) technology of Android, uses Baidu map API to obtain location information and draw activity track, and stores the information in the mobile phone SQLite database. The APP is installed on mobile phones, bracelets and other devices carried by the elderly and staff, which can record the current position of the person in real-time and simultaneously transmit it to the computer. When the elderly enter into a dangerous area, the system can quickly select the nearest staff and inform them for rescue, so as to ensure the safety of the elderly. After simulation test, the system has now reached the preset function.
Highlights
China has become the country with the largest elderly population in the world, and the singlechild family system has become the backbone of society
The mobile APP realises real-time positioning, stores the activity track into the mobile phone and sends the obtained information to the computer program; the computer program is responsible for personnel information management, path management, fence setting, real-time display of the location of the elderly and danger alarm; HTTP protocol is used between the mobile APP and the computer program to realise the network communication between the APP and the computer program, and representational state transfer (REST) is used for data transmission format for data encapsulation, to ensure the rapid and safe transmission of information
The mobile terminal has the functions of setting fence information, storing track, giving alarm when entering dangerous area, obtaining position information in real-time, displaying activity track in real-time on Baidu map and drawing a historical track
Summary
China has become the country with the largest elderly population in the world, and the singlechild family system has become the backbone of society. There is an urgent need for a system that can monitor the activity route of the elderly, analyse their activity rules, locate their whereabouts in real-time and carry out risk warning. The concept of location-based service (LBS) [1] appeared in the United States as early as 1996 At that time, it mainly provided rescue teams with the location information of the helpers, so as to facilitate quick rescue. Due to the late development of China’s pension institutions and the relatively low degree of information technology, the activity management of the elderly mainly depends on manual work. It is necessary to use LBS technology to develop a software system that can monitor the activity routes of the elderly, analyse their activity rules, locate them in real-time and carry out risk warning
