According to demographic data published by the national Bureau of statistics: 24949 ten thousands of people in 60 years old and over in China account for 17.9 percent of the general population and are increased by 859 thousands at the end of 2018; 16658 million people in 65 years and older account for 11.9% of the total population, with an increase of 827 ten thousand. In contrast, the proportion of elderly people with alzheimer's disease is increasing in the context of aging. According to survey, about 950 million Alzheimer's disease patients account for one fourth of the total number of the patients in the world in China. Such populations suffer from symptoms such as memory impairment, loss of speech, misuse, agnosia, impaired visuospatial skills, impaired executive function, and personality and behavioral changes. The modern society is faster and faster, and children work in other places or even abroad, and have no way to accompany the old, and even the old suffering from the Alzheimer disease, and people around need to watch and nurse all the time. So that a part of children may choose to send the elderly to a medical service center or a nursing home. The elderly suffering from alzheimer's disease are easily lost due to memory impairment without career attention, and thus, the elderly may bring great troubles and worries to families and hospitals. According to investigations, it has been shown that there has been a breakthrough in recent years in respect of their treatment, but no satisfactory pharmaceutical intervention is currently available. The treatment mode for the patients with the Alzheimer disease can move the brains of the old through a scientific memory training scheme, can effectively prevent the brain aging and can slow down the memory deterioration speed. But currently there is a lack of corresponding auxiliary equipment. An Ultra Wide Band (UWB) technology is a wireless carrier communication technology, which does not use a sinusoidal carrier but uses nanosecond-level non-sinusoidal narrow pulses to transmit data, and thus, the occupied frequency spectrum range is Wide. The UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, is suitable for positioning indoors or in commercial districts, and the positioning accuracy can reach centimeter level.
