With the continuous development of society and the continuous improvement of people's lives, people tend to be more convenient, faster and smarter lifestyles. The One Card System is increasingly favored by major companies and universities. The new generation of one-card system uses IC card technology, biometrics technology, computer network technology and other modern technologies to conduct personnel identification management of corporate offices, equipment rooms, and conference rooms. Through the construction of the one-card system, it can facilitate the management of entry and exit of enterprise personnel, and one card can enter and exit all places where there is authority to enter and exit, and realize the information management of personnel activity areas. The use of advanced Ethernet network communication technology enables real-time monitoring of the entire office area and recording of personnel's access time.
However, the traditional 232 card system requires a computer to control a single card system. For large enterprises, more than one card access control system requires more computers to control and requires more financial and material resources and manpower. Trouble and the communication distance is less than 1200 meters. Generally, large companies have many branch offices distributed throughout the country, so that the 232/485 card system can not meet the needs of large companies. In order not to let the traditional 232/485 card system be eliminated prematurely, Lingchuang Technology has introduced a serial port to TCP/IP solution, adding a serial port to Ethernet module NEPORT on the original serial port 232/485, NEPORT with its compact The volume is easily embedded in the original circuit system. NEPORT is derived from the development of the 32-bit ARM7TDMI core from the German company UCLPU. It has powerful data processing and expansion capabilities and can handle a large amount of data and issuance volume. Such data processing capability is generally based on the SCM architecture. Unable to bear. Real-time transmission of monitoring data through serial port to Ethernet can transmit 10,000 monitoring information in 1 second. Its processing capacity is several thousand times that of the control equipment based on 485 network, meeting the real-time monitoring requirements of access control systems of any size. Through the integration with other monitoring subsystems, the automation and intelligence of the entire office area can be improved, and comprehensive digital security can be achieved. Can be directly on the Ethernet, can be seamlessly connected with the user information management system. The traditional card system's real-time monitoring, openness, standardization and advancement have been completely resolved.
