Generally speaking, after entering old age, physiologically, it will exhibit characteristics such as slowed metabolism, decreased resistance, and decreased physiological functions. This is a natural law, so the cognitive decline of the elderly is difficult to reverse. Elderly people often forget where items are placed, they forget to bring keys when they go out, chaos in money management, inconvenience, confusion, communication problems, more physical emergencies, and less diagnosis time. In order to solve these problems, many smart technology companies have developed application systems such as personnel positioning, emergency help, identity authentication, case management, item management, entrance and exit management, access control management, and consumption management. The RFID system for the elderly usually consists of four parts: smart tags, sensing equipment, support modules, and application systems.
According to the technical characteristics of different frequency bands, RFID smart tags can be divided into: Low Frequency, High Frequency, Ultra High Frequency, and Microwave. Can also be classified by passive RFID products, active RFID products, semi-active RFID products. Semi-active RFID products, combining the advantages of active RFID products and passive RFID products, under the trigger of the low-frequency 125KHZ frequency, let microwave 2.45G, 433M, WIFI take advantage, and compound a 13.56M high-frequency card for One card is widely used in the existing old-age care system. Semi-active RFID technology, also known as low-frequency activation trigger technology, uses low-frequency close-range precise positioning, microwave long-range identification and uploading data to solve functions that pure active RFID and passive RFID cannot achieve. Simply put, it is to activate positioning at short distances, identify and upload data at long distances. These tags are made into a wristband or pendant for easy wearing. ISO / IEC has developed air interface protocols in five frequency bands to regulate the information exchange between RFID sensing devices and smart tags.
RFID sensor devices are often installed in identification areas, such as in the doorways of senior apartments, in the ceilings of buildings, and on the pillars in outdoor areas of elderly communities, etc., to identify smart tag information in a certain area for identification and positioning, and to receive the received Information is transmitted to the background through the support system.
The support module and application module mainly collect and analyze the sensing equipment and tag data, further processing, providing a docking interface, which is used by people, and is the core of the elderly health care system. The wristband (pendant) tag can intermittently send information to the sensor devices in the area, and send real-time updates to its management center. Once the information of the elderly is not uploaded to the system management center, an alarm will be issued, and the staff can view the elderly in the previous Phase activity trajectory to deal with unexpected situations in time. The RFID tag is basically equipped with an emergency call SOS function. When the elderly need help, as long as the emergency call button on the RFID tag is pressed, the nursing staff can accurately locate based on GIS, respond quickly, and help. If an elderly person has an illness, the system can quickly retrieve the elderly's case, health record, and life record according to the situation, and provide the necessary information to cope with this sudden situation. When the SOS alarm function is activated, the video surveillance system will also be activated in conjunction with controlling the cameras in the corresponding area, switching to the specified direction, displaying the scene picture, and providing accurate video information for the management staff. Some elderly people need special care. Managers use the system to record and send them to all the caregivers. The caregivers read the tags of the elderly through the RFID induction device worn by them to facilitate personalized services. In addition to the above applications, it also includes one-card functions, such as apartment access control, community restaurants, entertainment and fitness venue authentication, etc.
Most of the RFID tags worn by the elderly now upload data in one direction, which is limited to help, personnel positioning, and card functions, and does not implement the active event reminder function. The price of passive ultra-high-frequency 900M sensing equipment is high. The problem of power supply of active 2.4G electronic tags and the problem of excessive weight of the tags themselves. Lack of industry standards. Too many indoor radio frequency devices may cause the electromagnetic spectrum to be very crowded. Inductive devices frequently read tags repeatedly, occupying communication channels and server resources, some RF signals may be absorbed by the human body or blocked by metal objects, how to assign alarm signals to appropriate medical institutions, the effects of wireless signal radiation on the elderly body, etc. It is tricky and hinders the practical problems of RFID technology application in elderly health care. So if RFID tags can be integrated with health-type wearable devices, it will provide more help for the elderly.
The intelligent system combined with RFID technology provides important support for the independent life of the elderly, can help the elderly solve various problems in daily life, and improve the self-confidence of the independent life of the elderly. However, all systems have some limitations. This requires the participation of professional large-scale technology companies and relevant industry experts. It requires the development of equipment docking standards, the need to reduce system costs, and the need for technical development and legal regulations. It is a further exploration of RFID technology in the health care of the elderly. And research support.
