无线定位系统在养老社区特定场合的实用性和必要性已经日趋显著,其应用前景广阔,研究意义重大,阐述几种常用的无线定位技术手段,详细对比其准确度及优缺点,寻求合理的解决方案。随着时代飞速变迁,无线定位技术迅猛发展,信息服务质量效率提高,具有较大的拓展空间,尤其是在养老社区中其应用前景广泛。定位系统有最基本的五种算法:①起源蜂窝小区技术。②时间到达法(TOA)。③时间到达差法(TDOA)。
The practicality and necessity of wireless location system in the special occasions of pension community have become more and more obvious. The application prospects of the wireless location system are significant and the research is of great significance. Several commonly used wireless location technologies are elaborated, and their accuracy, advantages and disadvantages are compared in detail to seek a reasonable solution Program. With the rapid changes in the times, the rapid development of wireless location technology, information service quality and efficiency, with greater room for development, especially in the elderly community in its wide range of applications. Positioning system has the most basic five algorithms: ① origin cellular technology. ② time to reach the law (TOA). ③ Time to reach the difference method (TDOA).
