I. Introduction
With the progress of society and the development of science and technology, people pay more and more attention to the life safety of the elderly. Due to the gradual decline of the memory and reaction ability of the elderly, they are easy to get lost or encounter accidents when going out. Therefore, in order to ensure the safety of the elderly, various elderly anti-loss devices came into being. Among them, the use of ultra wideband (UWB) technology locator because of its high precision, low power consumption and other advantages, gradually become the new favorite in the market.
Second, the market demand for the elderly anti-loss device
With the deepening of China's aging society, the security problem of the elderly is becoming more and more prominent. According to the National Bureau of Statistics, by the end of 2021, China's elderly population aged 60 and above will reach 267 million, accounting for 18.9 percent of the total population. It is expected that by 2035, the elderly population aged 60 and above will exceed 400 million, accounting for more than 30% of the total population. There is a growing demand from children to ensure that their parents get home safely when they are away. At the same time, communities, nursing homes and other institutions have also expressed a strong interest in such products, hoping to ensure the safety of the elderly through scientific and technological means.
Iii. Principle and application of UWB technology
Ultra-wideband (UWB) technology is a carrier-less communication technology that transmits data using narrow pulses of non-sine waves from nanoseconds to picoseconds. Because of its strong penetration, low power consumption, strong anti-multipath interference ability, it is especially suitable for high-precision positioning. In the elderly anti-loss device, UWB technology can provide centimeter-level positioning accuracy, which greatly improves the efficiency of finding the elderly. Compared with traditional GPS positioning technology, UWB technology can also maintain higher positioning accuracy and stability in indoor environment. In addition, UWB technology can also achieve two-way ranging and high-speed data transmission, providing more functions and possibilities for the elderly anti-loss device.
Fourth, the functions and characteristics of the elderly locator
The elderly locator based on UWB technology has the following functions and features: real-time positioning, electronic fence, emergency help, historical track query, etc. Children can check their parents' location at any time through the mobile APP, and the phone will receive an alert if the parents step out of the set electronic fence. In addition, in the event of an emergency, parents can quickly signal for help through the SOS button of the locator. The locator can also record the parents' historical trajectory, helping them to recall the route taken.
5. Comparison of the elderly anti-loss device UWB locator on the market
At present, there are many brands of elderly anti-loss device UWB locator on the market, each brand has its unique product characteristics and advantages and disadvantages. When choosing the right locator, consumers need to consider multiple factors such as accuracy, battery life, waterproof rating, and portability. At the same time, price is also a big consideration, and consumers need to make trade-offs based on their needs and budgets.
Six, how to choose the appropriate elderly anti-loss device UWB locator
The following factors need to be considered in choosing a suitable UWB locator for the elderly: First, choose products with high brand awareness and good reputation; Secondly, we should pay attention to the performance and functions of the product, such as positioning accuracy, battery life, waterproof level, etc. Third, to consider the portability and comfort of the product, convenient for the elderly to carry and use; Make trade-offs based on your budget and choose products that are cost-effective.
7. Use and maintenance
The following points need to be noted when using the UWB locator for the elderly: First, check the battery power regularly to ensure the normal operation of the equipment; Secondly, it is necessary to avoid using the locator in a metal box to avoid affecting the positioning effect; Thirdly, keep the positioner dry and clean to prevent water vapor and dust from causing damage to the equipment; When you encounter problems, you can contact after-sales customer service for consultation and treatment.
