Research And Development Of Automatic Sign-in System Based On Wifi And Cell Phone Camera

With the continuous improvement of the employer's management mechanism,the unit's attendance forms gradually become diversified.How to more effectively manage employee attendance becomes a problem that employers need to solve.The forms of check-in are various,from initial signing(verbal answer),signature signing,and then to subsequent electronic sign-ups,such as fingerprint sign-in,face recognition sign-in and so on.The form of attendance gradually becomes diversified,and different forms of attendance are suitable for different attendance scenarios.Therefore,it becomes more efficient to select an appropriate check-in form according to different scenarios.The purpose of this system is to facilitate attendance checking,reduce attendance management cost and solve the problem of cheating.The main users of this system are attendance management personnel and employees on duty,combined with the company's actual attendance management system,and thus developed a duty attendance management system that records,analyzes,and analyzes the attendance of employees on duty.With this system,multiple ways of signing in(check-out)can be achieved,and only the use of a personal mobile phone for sign-in operations is required.The user's operation is convenient,and its flexibility and convenience are greatly improved compared to other attendance forms.The work done in this paper:1)Check in using wifi.The sign-in method makes full use of the wifi resources of the employer,and the sign-in method is convenient and fast.2)Use mobile phone to upload photos to check in.Photo check-in ensures that you can sign in where the employer does not have wifi.Upload the photos and save the longitude and latitude of the location to the database,ensuring the accuracy of the check-in location.3)A random check-in mechanism is adopted to ensure that attendants on duty do not leave the job midway.During the on-duty time of the on-duty personnel,thesystem randomly sends the on-duty instructions to the on-duty personnel.The on-duty personnel need to check in at the designated place within the specified time to ensure that the on-duty personnel are on duty at all times.4)Diversified scheduling methods reduce the cost of attendance management.Attendance management can use excel form the way to sign in assignment of the personnel on duty,can also add a sign in a detailed task,according to the different application scenarios choose different methods of scheduling,reduce the information management and maintenance cost of unit of choose and employ persons.5)Measures to prevent cheating in attendance: collect the MAC address of the mobile phone and prevent others from signing in;The ability to select photos from the album is restricted in the photo check-in of the mobile phone.Only the functions that support the photo and upload can prevent the sign-in personnel from checking in on the spot.With the increase in the number of attendance and the improvement of attendance,there will be a large amount of attendance data.At this time,the storage,retrieval,and data maintenance of massive attendance data will meet challenges.The loading of the attendance statistics list page in the attendance information statistics module will become slow.The solutions are as follows:(1)Using Hadoop to store and maintain a large amount of attendance data,storing attendance data on the HDFS of the Hadoop system;(2)Using Elastic Search to implement attendance information statistics and implement a field Real-time search;(3)The display of diversified attendance data with the data display tool kibana.The system can display attendance statistics such as late arrival rate,early withdrawal rate,appointment rate,number of attendances,and number of attendances in kibana.Sign in rate of attendance data by ARIMA model to model,based on previous attendance data to predict future attendance data,scheduling of attendance management has guiding significance.Practice shows that this system can realize the function of signing in(check-out)based on two forms of “wifi” and “mobile phone photographing”;ordinary attendanceusers can easily complete the attendance task;attendance managers can efficiently realize personal check-in and sign-out information And scheduling information management and maintenance.Under the massive attendance data,the distributed tool system can be used to store,maintain,and retrieve attendance data.
