摘要
工业物联网的网络拓扑结构复杂,包含多个层级和多种类型的网络设备。然而,数据在传输过程中需要经过多个节点转发,每个节点都会存在一定的处理延迟,导致整体数据传输延时增加。针对该问题,提出了基于5G通信的工业物联网设备数据低延时传输方法。首先,构建了工业物联网通信传输时延模型。该模型充分考虑了5G通信的高带宽、低延时特性,以及工业物联网设备的多样性和分布性。其次,根据香农公式计算出信道容量的极限值,并以此为基准进行数据传输的规划。最后,设计了设备数据自适应延时公平调度传输方法,通过动态调整传输优先级,使得重要数据可以更快地通过各个节点,减少在每个节点排队等待的时间,从而在一定程度上缓解网络拓扑复杂导致的延迟。实例应用证明,该方法能够显著降低数据传输延时,提高传输效率,同时保证数据传输的公平性和可靠性,为工业物联网的智能化、自动化生产提供了有力支持。
The network topology of industrial Internet of Things is complex,including multiple levels and types of network devices.Data needs to be forwarded through multiple nodes during transmission,and each node will have a certain processing delay,resulting in an overall increase in data transmission delay.A low latency transmission method for industrial IoT device data based on 5G communication has been proposed to address this issue.Firstly,a communication transmission delay model for industrial Internet of Things was constructed.This model fully considers the high bandwidth and low latency characteristics of 5G communication,as well as the diversity and distribution of industrial IoT devices.Secondly,calculate the limit value of channel capacity based on Shannon′s formula and use it as a reference for data transmission planning.Finally,a device data adaptive delay fair scheduling transmission method was designed.By dynamically adjusting the transmission priority,important data can pass through each node faster,reducing the waiting time at each node and alleviating the delay caused by complex network topology to a certain extent.Case studies have shown that this method can significantly reduce data transmission latency,improve transmission efficiency,while ensuring fairness and reliability of data transmission,providing strong support for the intelligent and automated production of industrial Internet of Things.
