First of all, if an IC card is not issued in the network management workstation issuing system, it cannot be used in the system. After the administrator of the network management workstation logs into the system, he performs the IC card issuance operation, enters relevant information about the IC card, the network management station archives the relevant data of the issued IC card and all the operation records of the network administrator, and updates the relevant database in the network management station , And then send all the recorded data this time to the relevant data table of the web server database.
After the server database receives the data from the network management station, it updates the related data table and sends the data of the IC card to the corresponding management workstation according to the setting of the IC card authority at the time of issuance.
After each management workstation receives the data sent by the server, it updates the corresponding data table in this site. According to the content of the data, download the corresponding data to the on-site controller. The controller updates the data in the memory. If the added data exceeds the storage recording capacity, the controller adopts an overwrite method to overwrite the earliest entered data with the newly added data.
