Design And Development Of Laboratory Punch System Based On Android Platform

With the development of mobile Internet technology and the popularization of mobile smart devices,people are increasingly using mobile apps to deal with various matters in work,study and life.As a widely used information system,the attendance system also has a need for technological updates and upgrades.The traditional IC punch-in system has the problems of easy punch and loss.The fingerprint punch system has the problems of finger molting and dry skin affecting recognition,and the face recognition punch system has problems such as slow recognition speed and inability to customize development.Aiming at the above shortcomings,based on mobile phone terminals,face recognition technology,and speech synthesis technology,this paper designs a mobile attendance system to improve the convenience,intelligence and interactivity of the attendance system.This article systematically introduces the requirements analysis,functional design,key technology,database design,interface design,system development and testing of the laboratory punch system based on the Android platform.The overall design idea of this punch system is to first enter the basic information of the laboratory personnel into the system,and then use the laboratory punch machine for face recognition punch,or log in through your own Android mobile phone to log in and log-in to the LAN,ask for leave,and release the plan,Check the school calendar schedule and curriculum management;according to the type of personnel and attendance,the voice synthesis technology is used for external reminders.In the development process of this laboratory punch system,the currently popular Android development technology was used,and the design and implementation of the data table was completed conveniently and quickly by citing the LitePal database open source framework.The punch system uses Android Studio development tools to complete the development of all interfaces and business process codes of this system.
