随着社会的发展,人们对获取数据的需求从两个维度上产生了重大改变,一是数据传输量的需求大大增加,二是数据传输精度的需求也在显著提升。因此通信和定位是实现基于位置的高精度高速率信息传输的关键技术。本文从高速率无线可见光通信技术入手,探索了无线可见光通信技术的实现方法,深入分析了这种通信系统所应用的场景的特点,针对这些特点,我们重点研究了基于无线可见光通信的室内定位算法的设计,实现照明、通信和室内定位的功能复用。为了进一步充分发掘无线可见光通信的优点,我们还分析了基于无线可见光通信的利用位置信息的各种数据型应用。
With the development of society, people’s demand for data acquisition has undergone major changes in two dimensions. First, the demand for data transmission has greatly increased. Second, the demand for data transmission accuracy has also risen significantly. Therefore, communication and positioning are key technologies for implementing location-based high-precision and high-rate information transmission. This article starts with high-rate wireless visible light communication technology, explores the realization method of wireless visible light communication technology, deeply analyzes the characteristics of the scenes applied in this communication system, and according to these features, we focus on indoor positioning algorithm based on wireless visible light communication The design enables the reuse of functions for lighting, communication and indoor positioning. In order to further fully exploit the advantages of wireless visible light communication, we also analyzed various data-based applications that utilize location information based on wireless visible light communication.
