Attendance information management system is based on ASP technology development, using B / S mode, to achieve greater sharing of employee attendance information, authorized Internet users at any time anywhere through the browser to the Web server data access request . The system uses a three-tier network construction, including on-site control network, intranet and information release network.
The on-site control network is connected to multiple intelligent access controllers via an RS-485 serial bus, and communicates with the system server through RS-232/485 converters in real time. The field control network adopts the master-slave mode for multi-machine communication. The host is the system server of the system. The slave is the intelligent access controller for field control. Each slave has its own unique address, and the host controls each communication.
The internal network includes the LAN of the office building, where the enterprise attendance management department is the network center, and connects the various functional departments within the enterprise; the production management LAN is connected to the production workshops through twisted pair cables and switches. The LAN network design is a star Ethernet based on the TCP/IP protocol, implemented using 100Base-T and Super Category 5 twisted pair technology. The information publishing network uses Internet technology to implement reliable exchange of information with remote servers.
The construction of the system's network database is based on the management of employee attendance information, and the development of the network database is based on data entry, processing, aggregation, and management. The enterprise's attendance management department is the data integration management center and is equipped with the development database database query software. Adopt client/server and browser/server based access and operating modes. The client application connects to the network database by setting the name of the SQL Server server in ODBC.
