    Introduction to entrance guard system transmission way change

    2023-08-09 00:00:00
    , domestic door industry development with each passing day, whether it’s on the size of the market, or on the application of new technology, there is a lot of different.In these changes, some people think that transport entrance guard system is one of the biggest breakthrough, although it may not be completely correct, but still have a point.

    the traditional access control system mainly USES the RS - 485 bus, wigan communication mode, such as traditional protocols with the development of technology upgrade, there are a variety of transmission way used in the entrance guard system, such as wigan, RS - 485, TCP/IP, etc., the combined transport, together constitute the entrance guard system.Such as card reader and control machine use wiggins agreement link, between the lower controller via RS - 485 link with the main controller, and links to the control center can be via TCP/IP network connections.

    in addition to the wired network connection, also appeared a wireless Internet connection, form the integration of a variety of communications technology solutions, in response to different scenarios, the requirements of different customers.

    the current in the large entrance guard system, mainly USES is the combination of RS - 485 + TCP/IP architecture.RS - 485 connection between LAN equipment used in small scale, such as card reader and control machine, used to make up for the wigan agreement security problems.But because the RS - 485 output distance is limited, if you want to remote management and control of entrance guard system, still need to be transmitted via TCP/IP connection, this is the RS - 485 + TCP/IP double network architecture, the enterprise to meet requirements of access control management.

    , so to speak, with the development of network technology and the Internet, TCP/IP will be the entrance guard system common transmission mode.()
