摘要
随着电子信息技术的不断发展,雷达产品的集成度和复杂度日益提高,产品交付的资料难以全面有效地指导用户排查产品故障,而在产品使用过程中,大量的故障数据并没得到有效利用。基于数据的雷达产品快速排故技术是以雷达产品大量使用数据为主要输入,利用分层推理集合搜索技术模型,从雷达产品的层次结构入手,分析功能故障与系统故障的关系,利用有向图的传播路径,形成故障相关性矩阵。依据故障相关性矩阵,通过故障现象等数据输入,推理出有效的排故策略。形成故障排查指导手册等形式的指导文件,以指导用户快速定位故障,解决问题,提升用户自身的排故能力。
With the continuous development of electronic information technology,the integration and complexity of radar products are increasing,and the materials delivered by the product are difficult to guide the user to troubleshoot the product failures comprehensively and effectively.Furthermore,in the process of product usage,a large amount of fault data have not been effectively utilized.The data-based rapid troubleshooting technology for radar products uses a large amount of usage data of radar products as the main input,using hierarchical reasoning to aggregate search technology models,starting with the hierarchical structure of radar products,analyzing the relationship between functional failures and system failures,and using the propagation path of the directed graph to form a fault correlation matrix.Based on the fault correlation matrix,the technology infers effective troubleshooting strategies through the input of fault phenomena and other data,and forms guidance documents in the form of troubleshooting guides to guide users to quickly locate faults,solve problems,and improve uses’own troubleshooting capability.
