中文摘要:

为了缩短中压配电网网格搜索引擎系统平均响应时长,提升系统搜索召回率,设计一种基于图数据库的中压配电网网格搜索引擎系统。通过搜索器和接口设计系统硬件部分；系统软件部分包括中压配电网网格采集模块、图数据库存储模块和电网网格搜索引擎模块,通过中压配电网网格采集模块采集配电网中设备信息,采用广度优先遍历算法,逐个确认各设备的通电状态,利用图数据模型,通过图数据库存储模块对采集到的设备信息进行规范化处理,创建索引模块,利用关系数据库系统建立中介数据电子目录,根据电子数据目录逐个生成集合对象,根据集合对象创建数据文件,利用图文索引功能,通过索引模块对中压配电网的设备信息进行搜索,根据系统硬件和软件两部分设计完成基于图数据库的中压配电网网格搜索引擎系统设计。经实验证明,该系统的平均响应耗时短及用户满意度高,鲁棒性强。

英文摘要:

In order to shorten the average response time of medium voltage distribution grid search engine system and improve the system search recall rate, a medium voltage distribution grid search engine system based on graph database is designed. The hardware part of the system is designed through searcher and interface; The system software part includes the medium voltage distribution network grid acquisition module, the graph database storage module and the grid search engine module. The medium voltage distribution network grid acquisition module collects the equipment information in the distribution network, adopts the breadth first traversal algorithm, confirms the power on status of each equipment one by one, and uses the graph data model, Through the graph database storage module, the collected equipment information is standardized, the index module is created, the electronic directory of intermediary data is established by using the relational database system, the collection objects are generated one by one according to the electronic data directory, the data files are created according to the collection objects, and the graphic index function is used to search the equipment information of medium voltage distribution network through the index module, According to the system hardware and software design, the grid search engine system design of medium voltage distribution network based on graph database is completed. Experiments show that the system has short average response time, high user satisfaction and strong robustness.
