| 针对物联网控制规则在实际应用中，由于延迟触发执行导致物联网系统引发不同程度的控制安全事故，本文基于规则的实时特性提出了一种面向物联网控制规则的端云动态分配方法(EasiDEP)，以提高物联网系统控制规则的实时性。首先，根据规则之间的相关性以及实时特性，提出了一种规则聚类算法，将规则库中的规则分为实时和无实时规则；然后，基于规则聚类结果提出一种端云动态规则分配方法，将实时规则分发至云端和本地规则服务端同时处理，提高实时规则的触发执行率。最后，通过实验验证了EasiDEP能够有效地提高物联网控制规则的实时触发执行率，降低系统发生控制安全事故的风险。 |

| Aiming at the control rules of the Internet of Things in the practical application, the Internet of Things system causes different degrees of control security accidents due to the delayed trigger execution. Based on the real-time characteristics of the rules, this paper proposes an end-cloud dynamic allocation method (EasiDEP) for the control rules of the Internet of Things system, so as to improve the real-time performance of the control rules of the Internet of Things system. Firstly, according to the correlation between rules and real-time characteristics, a rule clustering algorithm is proposed, which divides the rules in the rule base into real-time and non-real-time rules.Then, based on the result of rule clustering, a dynamic rule allocation method is proposed to distribute real-time rules to the cloud and local rule server for simultaneous processing, so as to improve the execution rate of real-time rules.Finally, the experiment verifies that EasiDEP can effectively improve the real-time trigger execution rate of Internet of Things control rules and reduce the risk of control security accidents. |
