Attendance system overview
Planning objectives
Based on a high starting point, high standards, and high requirements, using the most advanced domestic smart card and fingerprint time attendance application mode, the following goals are achieved:
(1) The goal of digital office: to build the backbone platform of the “employee card” system. The various subsystems of identity authentication, canteen consumption, and attendance management are all built under this platform. In the future, it only needs to be expanded with the expansion of the scale of the enterprise and the increase of card functions. Increase the subsystem to achieve the goal of digital office;
(2) The goal of the all-in-one card: one card for each employee of the enterprise. This card integrates identity card, attendance card, consumption card, and medical insurance card. All-in-one card can be used inside.
The system design combines real-time transmission and offline operation, all-in-one card operation, and data sharing.
Technical characteristics
1. Advanced network communication structure. The star topology structure does not affect the operation of each other. Combining the advantages of offline application and real-time communication, using firewall and TCP/IP protocol to realize the docking and real-time communication between private network and local area network and terminal equipment.
2. Fingerprint application; as a supplement to the employee card, employee fingerprints can also be used as a method of attendance.
3. Three-tier software structure. The software adopts a modular component structure and a CS structure based on a local area network. The management personnel can perform corresponding operations on the system at any client according to authorization.
4. Large database structure. Using SQL Server 2000 database, the system has high security and reliability, and the operation is more stable.
5. Standard attendance processing function. Standardized report design and real-time data transmission ensure real-time attendance and daily check.
6. Convenient self-service function. Equipped with corporate inquiries, corporate culture publicity, help manuals and other supporting self-service functions to optimize the card environment and reduce management workload.
Attendance mode selection
Optional swipe card mode: use multiple storage areas on the card (up to 16 areas) to store the original card number. By swiping the card on the attendance cabinet, the identified card number corresponds to the personnel information in the system database. If the personnel information After the recognition is successful, the attendance record of the person can be uploaded to the database in real time, and the real-time photo of the employee’s profile picture will be displayed on the cabinet screen, as well as the employee’s name and department information.
Optional fingerprint punch-in mode: To use fingerprint attendance, the fingerprints of each employee must be collected in advance, uploaded to the database, and then updated to each attendance cabinet. When the employee signs in, only need to be in the attendance machine. Press your finger on the fingerprint recognition head, and the attendance machine will compare the fingerprint information at the moment with the corresponding fingerprint in the database. If the match is successful, the relevant information of the personnel will be displayed. The attendance check-in is successful and the fingerprint attendance is also current Use one of the most common attendance methods.
Advantages of One Card:
Employee card can be substituted: work permit, ID card, medical insurance card, meal card.
Application range:
Attendance: employee attendance, office access control.
China Aluminum Attendance Management System
The design of the attendance management system is composed of two basic modules: office building attendance management and factory attendance management.
1. Office building attendance management subsystem

Considering the particularity of the real-time attendance system, the real-time nature of the system is particularly important. The new system management software divides the different functions into two mutually independent operating areas during the design, namely: the system management area and the cabinet program area. The operator’s identity is required to enter the operating area, and for different operators, only special operations can be performed. In this way, on the one hand, the possibility of misoperation is reduced, and on the other hand, the safety of the system is increased.
The office building attendance management system is mainly composed of system management software, cabinet data acquisition software, and cabinet attendance machine. The system software all work under Chinese Win98, win2k, xp platform, use C#, sql server 2000 and other advanced programming tools to make and finish. All Chinese, graphical interface, hotkey online help, easy to learn and understand, and easy to operate.
1. System management area: Responsible for setting various system parameters, making system cards, collecting and uploading fingerprints, and inputting personnel information into various data sorting tasks. In the network version of the system, there are functions such as system users and workstation information maintenance. This area can only allow system administrators or super administrators (online version) who have been properly registered with the system to enter.
2. Operator management area: Its main function is to perform attendance scheduling, attendance record collection and analysis, attendance record summary, etc., various operations of employee cards (including: employee card issuance, re-issuance, etc.), this area only allows Operators who are correctly registered in the system enter.
3. Optional real-time transmission of data: convenient for real-time query of attendance reports and attendance records.
4. Multi-function attendance cabinet: Its main function is to support swipe card attendance and fingerprint attendance, and take photos to record the avatar information of the sign-in personnel. And display the person’s name, department and corresponding avatar information on the touch screen. At the same time, the attendance records are uploaded to the database for the attendance management system for data analysis. Click on the corresponding area of the touch screen to query relevant corporate information and rules and regulations.

Structure diagram of offline attendance system in factory area
Based on the actual situation of staff attendance in the factory, it was decided to adopt a non-real-time attendance system. Attendance management personnel in the factory do not need to know the employees’ work conditions in real time, but only need to collect the attendance records in the attendance machine every afternoon after the employees get off work. Therefore, the wall-mounted 8-inch screen S6 series attendance machine is used through U disk Collect daily attendance and sign-in information, upload it to an independent management database, and analyze the data on the basis of attendance management software to know the daily attendance status of personnel.
The factory attendance management system is mainly composed of system management software, U disk, and wall-mounted attendance machine. The system software all work under Chinese Win98, win2k, xp platform, use VB, sql server 2000 and other advanced programming tools to make and finish. All Chinese, graphical interface, hotkey online help, easy to learn and understand, and easy to operate.
1. System management area: Responsible for the setting of various system parameters, the input of personnel information, the upload and download of fingerprint characteristic values, the display and input of personnel photos, the query of attendance records, and the organization of various data such as reports. Only system administrators or super administrators who have been properly registered with the system can enter this area.
2. Non-real-time data transmission: personnel information, fingerprint characteristic values, operation logs, personnel photos and other information can be uploaded to the management system through U disk, or downloaded to the attendance machine.
3. Wall-mounted camera fingerprint attendance machine: Its main function is to support fingerprint attendance, and take photos to record the avatar information of the sign-in personnel. And display the person’s name, department and corresponding avatar information on the touch screen. At the same time, the attendance records are stored in the local database and wait for the attendance management personnel to collect attendance records, operation logs, personnel photos and other information through U disk or cross-wire.
