摘　　要：当前物联网调度系统在实际操作过程中,无法精准确定物联网数据状况,导致网络信息收集能力较弱,接入时间延迟率高。为此引入雾计算及RoF-DAS架构设计了一种新的物联网调度系统。硬件结构设计了检测模块、监控模块、定位模块,三个模块协调配合,检测外部数据信息,实现定位监控,增强信息收集能力。软件部分利用雾计算技术,连接硬件终端设备与云计算数据中心系统,并按照连接的组合顺序进行数据排列,在RoF-DAS架构控制下分析物联网的应用数据,由此完成物联网调度系统设计。实验将所设计物联网调度系统设计应用在车辆调度中,结果表明,该系统能够准确地记录车辆数据状况,相较于传统系统,延迟率提高了36.4%,具有实际应用价值。In the actual operation of the current Internet of Things scheduling system,it is impossible to accurately determine the data of the Internet of Things(IoT),resulting in weak network information collection capabilities and high access time delay rates.To this end,fog computing and RoF-DAS architecture are introduced to design a new IoT scheduling system.The hardware structure of it is designed with a detection module,a monitoring module,and a positioning module.The three modules coordinate and cooperate to detect external data,realize positioning monitoring,and enhance information collection capabilities.The software uses fog computing technology to connect the hardware terminal equipment and the cloud computing data center system,arranges the data according to the sequence of combination of the connection,and analyzes the application data of the IoT under the control of the RoF-DAS architecture,thereby completing the design of the IoT scheduling system.The experiment applies the designed IoT scheduling system to vehicle scheduling.The results show that the system can accurately record vehicle data.Compared with the traditional system,the delay rate of this system increases by 36.4%,which proves the practical value of the system.
