摘要
工业物联网传统的单路传输方式无法有效保证信息传递的机密性与完整性,在通信过程中容易发生信息传输错误进而产生安全风险.本文针对工业物联网环境下智能化生产线设备间感知信息的安全通信需求,构建了一种多重冗余的工业物联网智能产线安全通信模型,提出了一种工业物联网辅助路径多重冗余传输方法,有效防止因通信节点失效而造成数据传输失败,降低了初始通信数据被整体捕获的概率,提高了通信的安全性.此外,针对安全通信模型由于特殊因素造成通信数据周期性丢失的特殊情况,本文进一步提出了一种智能产线通信缺失数据预测方法.该方法对于25个周期温度预测目标的多周期预测结果误差控制在0.15℃之内,在安全通信模型失效的特殊情况下有效预测填充了连续周期缺失通信数据,满足了工业物联网智能产线对于通信数据的完整性要求.
The traditional one-way transmission method of the Industrial Internet of Things(IIoT) cannot guarantee the confidentiality and integrity of information transmission effectively.In the communication process,information transmission errors are prone to occur,which may cause security risks.Aiming at the security communication requirements of perception information between intelligent production line devices in the IIoT environment,this paper constructs a multi-redundant secure communication model for intelligent production line of IIoT,and proposes a multi-redundant transmission method for auxiliary path of IIoT.This method can prevent data transmission failure effectively caused by the failure of wireless communication nodes in intelligent production lines,reduce the probability of data packets being intercepted by malicious nodes,and enhance the security of communication.In addition,aiming at the special situation that multi-redundant secure communication model fails periodically due to the special factors,this paper propose a method for predicting missing data in intelligent production lines communication further.In this method,the error of multi-cycle prediction results for 25 cycles temperature prediction targets is controlled within 0.15℃.In the special situation of failure of secure communication model,it can predict and fill in the missing communication data of continuous cycle effectively,which meets the integrity requirements of communication data for intelligent production line of IIoT.
