【摘要】：设计并实现了一种基于标签法的LED(发光二极管)室内可见光定位系统。在满足基本照明需求的同时,将当前的位置信息循环加载到LED光源上,通过无线光链路传输到移动终端,系统根据移动终端接收到的信息解析出其在环境中的相对位置,还可将位置映射到地图上并映射出与当前位置相关的提示指令,最终实现可见光定位。利用Stm32处理器作为系统主控制器,设计了一种适用于可见光定位的编码协议,以灵活可靠地传输位置信息。发射端测试了LED光源特性及驱动电路,可保证基本的照明与通信;接收端利用C#语言设计上位机软件以实现移动终端在地图上的映射及实时更新功能;结果表明,该系统定位效果理想。
[Abstract]:A LED (light emitting diode) indoor visible light location system based on label method is designed and implemented. While satisfying the basic lighting requirements, the current position information is cyclically loaded on the LED light source and transmitted to the mobile terminal through the wireless optical link. According to the information received by the mobile terminal, the system analyzes its relative position in the environment. The location can also be mapped to the map and the prompt instructions related to the current position can be mapped to achieve the location of visible light. Using Stm32 processor as the main controller of the system, a coding protocol suitable for visible light location is designed to transmit position information flexibly and reliably. The transmitter tests the characteristics of LED light source and the driving circuit, which can guarantee the basic lighting and communication, and the receiver uses C # language to design the upper computer software to realize the mapping and real-time updating function of the mobile terminal on the map. The positioning effect of the system is ideal.
