基于角反射可见光通信的净零能耗物联网技术研究与实验验证
Research on VLBC-based net-zero-energy IoT with experimental verification
摘要
Abstract
As the 6G era approaches,the number of Internet of things(IoT)terminal devices has rapidly increased,lead-ing to a significant increase in battery consumption and maintenance costs.As a result,achieving net-zero energy con-sumption has become one of the key technical requirements for promoting the widespread adoption of IoT terminals.Vis-ible light communication(VLC),as an emerging green communication technology in recent years,can effectively utilize existing lighting sources to carry downlink information,while terminal devices can use solar panels to simultaneously ac-quire both information and energy.However,traditional VLC uplinks typically rely on infrared communication technol-ogy,which imposes higher energy demands on terminal devices,making it difficult to achieve the goal of net-zero energy consumption.Accordingly,a novel net-zero energy IoT technology solution was proposed,which integrated solar-panel-based visible light communication with retroreflector-based passive visible light communication,and a prototype was con-structed.This solution aimed to achieve net-zero energy consumption for IoT terminal devices by enhancing energy har-vesting efficiency and reducing wireless transmission energy consumption.Experimental results showed that the proto-type could achieve a transmission distance of over 50 cm under indoor natural lighting conditions,with downlink and up-link transmission rates reaching 4 300 bit/s and 50 bit/s,respectively,making it suitable for short-range,low-rate IoT ap-plication scenarios such as smart locks.Furthermore,due to the adoption of passive uplink transmission,the required so-lar panel area for achieving net-zero energy consumption in terminal devices was reduced from 615 mm² to 125 mm²,sig-nificantly enhancing the deployment flexibility of the terminal devices.关键词
