摘要
作为当前传感网络和机器自动化的一种重要应用,无人自助超市受到广泛关注和研究。随着万物互联时代的临近和无线电频段资源的紧张,可见光通信技术及自动化技术显示出极大的优势。该系统基于STM32F767IGT6单片机,通过采用卡尔曼滤波和一种基于FFT的定位算法,运用修正的三边定位法实现了室内三维定位,并具有室内导引、无人检测称重计费及防盗的功能。按顺序介绍了该系统的硬件组成、软件思维导图及数学原理,并提供了详细的分析论证。该结构简单、成本较低、功能较传统超市较为完善。
As an important application of sensor network and machine automation,unmanned supermarket has been widely concerned and studied.Accompanied by the generation of the Internet of things and the shortage of wireless electronic frequency band,VLC and automation technology show many advantages.Based on STM32 F767 IGT6 microcontroller,via Kalman and a kind of FFT positioning algorithm,this system realizes indoor 3 D positioning,guiding,weighting to calculate the price and guarding functions by using triangulation-positioning method.The hardware design,software mind mapping and its math theory are introduced in order,and gives a detail analysis and certification.It has a simple structure,lower cost and better function than traditional unmanned supermarket.
