Design And Implementation Of Integrated Audit Management System Of Power Supply Company Based On Big Data Technology

With the development of Power Grid Corp's audit work,audit information construction has been deepened,and a large and varied audit resource has been accumulated.It has the foundation of developing big data applications.At present,big data application power audit area is relatively small,its value has not been fully excavated and large-scale application of audit data,and in the context of large data,audit mode and traditional methods can't meet the needs of the development of audit work power,facing many challenges,such as disorder engineering audit,large sampling risk owing to large-scale audit data,restrictions of time and place,simple audit contents and methods,low utilization rate of audit results,and hysteresis of audit methods.Therefore,it needs to optimize the audit process,establishes an integrated audit work mode,achieves high efficient storage and analysis application of massive audit resources based on big data technology,and constructs city and county integrated audit management system of power supply company based to improve the management level of power company audit.Firstly,this paper analyzes the research background,existing problems and main content of integrated audit management system of power supply company based on big data.Based on UML case diagram,it analyzes the needs of modules,such as audit project management,audit expert management,audit integrated management,audit problems management,audit results analysis,audit big data analysis,and system management.It designs each module based on class diagram,designs typical business execution logic and method based on time series,and designs database and data information table in detail.Based on workflow technology,it constructs the integrated audit management mode of power supply company to achieve scientific management of audit work.Based on HDFS+Oracle,it constructs audit big data storage framework,which realizes efficient storage of massive structured and unstructured audit resources.Based on MapReduce,it constructs audit big analysis framework,and the data is processed in parallel processing,so as to realize the big data analysis application such as audit doubt mining and clue analysis,project risk warning and so on.Based on the research of audit integrated management model and audit big data storage and analysis framework,this paper implements the integrated audit management system of power supply company based on B/S architecture,and analyzes the realization effect of each business function module,especially the typical application.The system is tested in order to find the problems and improve the system in time.Finally,the work done in this paper is summarized,and the future promotion of the integrated audit management system is prospected.This paper constructed the integrated audit management system of power supply company.Based on workflow technology,it established the integrated audit mode,which changed disorder audit,realized combination of on-site audit and remote audit,reduced audit time and cost,and improved audit efficiency.Based on big data technology,it established audit big data storage and analysis framework,which achieved efficient storage of massive audit resources,avoided audit sampling limitations and risks,improved audit timeliness and quality.It realized audit doubts mining and clue analysis of,and improved audit efficiency and accuracy.It realized the comprehensive application of audit results,and provided the decision support for audit departments and business departments.It realized project risk early warning,and improved audit foresight.
