Analysis of Access Control Board TCP/IP Communication Mode
Access Control Board networking solution realizes communication automation, office automation and management automation. It is based on integrated wiring system and uses computer network as a bridge to realize comprehensive management of communication system and office automation system.
TCP/IP communication protocol is the current computer network universal standard protocol, which has the advantages of fast transmission speed, international standard and good compatibility. The access mode of the controller is the same as that of the HUB of the local area network and the computer network card.
1. Communication distance: In a small local area network, the communication distance can be extended by the cascade of HUB. The communication distance of each level is up to 100 meters, and multiple levels can be cascaded. Moreover, in large-scale local area networks, it can be extended to a long distance or even a few kilometers through various methods such as fiber-optic wireless, and even across cities, it is also possible to connect thousands of kilometers through the Internet.
2. Number of loads: There is no limit in theory. The HUB can be cascaded, and there are no problems in tens of thousands of controllers.
3. Communication speed: The communication speed is fast. The communication speed of TCP/IP (RS485 to Ethernet) products is 10 times or even tens of times of RS485 and RS232 controller. Upload permissions or download records of more than 100, or even hundreds, per second.
Advantages of TCP/IP Networked Access Control Board: Adopting international standard popular communication protocol, the advanced nature and performance are better, and will not be eliminated for many years. The number of networking is unlimited, the network is wide, and it can be cross-regional or even cross-border.
The communication speed is fast, suitable for over 10,000 people, and over 100 access control boards. The communication quality is stable and not susceptible to outside interference. If the user already has a network such as a local area network, it is not necessary to re-lay the network, and the existing network is used to form a secure access control system.
