Portable Face Attendance System Based On Android System

At present,all enterprises and institutions pay more attention to the security of entrance guard,and most of them adopt the way of punch card,fingerprint or face recognition to complete the work of attendance.The convenience of carrying,data management and statistical summary of this way of attendance checking are inadequate.This paper mainly studies the portable face attendance system based on Android.It adopts face recognition technology and realizes portable face attendance management through Android mobile terminal,which ensures the accuracy of attendance and improves the efficiency of attendance.The functional modules include user management,data management,attendance management,system background.It is based on the existing problems in personnel attendance,this paper proposes the portable face attendance requirements with the combination of face recognition technology,aiming at improving the efficiency of attendance,and completes the system demand analysis.Through demand analysis,the business process of face attendance is understood,and then the functions of the system are realized.The system functions include user management,data management,attendance management,system background,etc.Through system function analysis,the functions of mobile terminal and background management of the system are mastered.Combined with the system operating environment,the system non-functional requirements analysis is completed.On the basis of demand analysis,the overall design of the system is completed,in which the system server adopts JavaEE architecture and the mobile terminal adopts Android,including business relationship layer,system function layer,data support layer,presentation layer and other multi-layer structure design,and the system database design is completed through the database conceptual model and physical model.System summary design,after the completion of the analysis,complete the user management module,data management module,attendance management module and system background module,at the same time draw the sequence diagram and class diagram to represent the system each module of the design process,these function modules built a portable facial attendance system,including user management to complete all attendance object registration and management,data management are used to implement the attendance data of import and export,attendance managementimplementation based on face recognition mode of attendance and artificial attendance function,the combination of system background face data acquisition to the background,the process of feature recognition through four function modules,A unified management platform integrating mobile terminal attendance checking and background data statistics and summary is built.After completing the module design,the server USES JavaEE to complete the technical implementation of each module.When implementing the module,it USES typical functions to describe the implementation process.After the realization of the function module,the paper selects the typical function and completes the function and performance test of the system.Test results show that the system functions to meet the face attendance requirements;The performance of the system can satisfy the company's multi-user concurrent access,and the system runs stably.
