摘要
针对老旧录波器无有效的安防整改措施而不得不脱网运行的现状,以及海量录波数据共涌造成的主站系统运行负担过重的问题,文章提出了一种基于录波器合规并网的数据分层治理和安全防护架构。利用规范化部署的合规并网装置解决脱网录波器合规并网问题,设计录波数据分层治理架构,应用基于变分模态分解样本熵和核极端学习机的录波数据预诊断技术进行故障初判,采用基于动态访问控制和加密传输的信息安全防护技术进行故障信息的安全传输,利用合规并网装置与录波器连接距离短的优势进行定制业务协同提高主站整体性能。实验结果表明,该方法可实现95%的扰动数据过滤和故障信息安全传输,达到主站故障诊断和风险预警性能提升的目标。
In view of the current situation that the old wave recorder has to run off the network without effective security rectification measures,and the problem of excessive operation burden of the master station system caused by the common surge of massive wave recording data,this paper presents a data hierarchical governance and security protection architecture based on wave recorder compliance network access.Standardized deployment of compliant network access devices are used to solve the problem,a hierarchical governance structure of recording data is designed,recording data pre-diagnosis technology based on VMD sample entropy and KELM is used for fault preliminary judgment,information security protection technology based on dynamic access control and encrypted transmission is adopted for fault information secure transmission,and customized business coordination is performed taking advantage of the short connection distance between the compliant network access device and wave recorder to improve the master station overall performance.Experimental results show that this method can achieve the goals of 95%disturbance data filtering and fault information secure transmission,and improve the performance of the master station's fault diagnosis and risk early warning.
