一种复杂环境下基于物联网的墨水屏电子标牌终端组网方案

A Networking Solution Based on IOT for Signage Terminals using Electronic Ink Screen underComplex Environment

墨水屏电子标牌终端传统采用星形组网结构,在复杂的环境下存在通信距离有限、易受干扰等问题,在实际应用中受到较大的制约,为此,设计一种复杂环境下基于物联网的墨水屏电子标牌终端组网系统。在传统星形组网结构的基础上,增加墨水屏电子标牌终端转发数据包机制和通过运营商的窄带物联网(NB-IoT)接入网络的功能,并设计终端选择接入方式的算法,实现了复杂环境下墨水屏电子标牌终端的灵活接入,提高了系统的可靠性。

Signage terminals using electronic ink screen used to be connected in star interconnec-tion network,itscommunication distance is limited and data transmission is Easy to be dis-turbed,so it is restricted in many scenes.A networking solution based on IOT for signage ter-minals using electronic ink screen undercomplex environment add functionality to the base of star interconnection network,using NB-loT and packet forwarding mcchanism to improve per-formance.In addition,this Solutiondesigns an algorithm for Signage terminals using clectronic ink screen to connect network in appropriate way,it can Improve the system reliability.
