摘要:
针对电源调试过程中设计者经验不足,认知水平有限等问题,提出了一种基于知识图谱技术的辅助电源调试方法。通过分析德州仪器的电源管理实验套件TI-PMLK,挖掘出开关电源主要包含的性能指标以及影响它们的各个因素,并作为知识图谱的实体节点。基于电源设计软件Webench仿真得到数据,再将数据导入到统计学软件SPSS进行相关性分析,得到电源性能指标与各影响因素之间的相关性系数矩阵。矩阵中的系数作为知识图谱中边的属性,表示节点之间相关性的强弱。最后,基于图形数据库Neo4j构建出电源知识图谱,将电源性能指标与影响因素之间的复杂关系展现出来,以辅助设计者进行电源调试。
Abstract:
In order to solve the problems of insufficient experience and limited cognitive level of designers in the process of power debugging,an auxiliary power debugging method based on knowledge graph technology is proposed.Firstly,by analyzing the Texas Instruments Power Management Lab Kit TI-PMLK,the performance indicators mainly included in the switching power supply and the various factors affecting them are extracted and used as the entity nodes in the knowledge graph.Secondly,the data are obtained based on the power design software Webench simulation,and imported to the statistical software SPSS for correlation analysis. The correlation coefficient matrix between the power supply performance index and the influencing factors is obtained.The coefficients in the matrix,as the property of the edges in the knowledge graph,represent the correlation between nodes.Finally,based on the graphic database Neo4j,the power supply knowledge graph is constructed,and the complex relation between the power supply performance index and the influencing factors is presented,so as to assist the designer to carry out the power supply debugging.
