WiFi Check-in System Based On OpenWRT Technology

With the development of society and the progress of science and technology,attendance management sign can't just rely on paper to sign,through the computer aided system for attendance management has become a big trend,at the same time,also can greatly save manpower and material resources,avoid the waste of resources and cost.At present,most of the high-class attendance management system can complete the task of attendance,and the hardware system is perfect,but the corresponding management software is not enough.Some attendance items,such as overtime,leave and going out,cannot be recorded.In attendance management system,on the basis of a detailed requirement analysis,this paper designed a WiFi attendance management system,through the mobile phone login WiFi sign in,greatly improve the efficiency of the attendance management,is also a great way to save costs,just rely on the router and computer can manage attendance.Based on the intelligent WiFi attendance statistics system,including intelligent WiFi device and background server two parts,and according to the function realization is divided into modules.The system is divided into three modules according to the function implementation,namely data acquisition module,data transmission module and data processing module.Check-in process is mainly based on OpenWRT system intelligent WiFi devices access to sign in the MAC address of the information,the computer by connecting to WiFi will sign in information transmission and storage,at the same time,using LabVIEW software design sign in the data processing module,to sign in information processing,so as to realize the management of staff attendance.Finally,the system is tested under different environments,and the results are analyzed and studied.The test results show that in different environments,the WiFi check-in system can complete the check-in management quickly and accurately,and record and query the sign in information.The research in this paper provides a reference for the innovation of the sign in system.
