Discussion on the management method of LED display IP address

At present, LED display screens are mainly used in two situations, one is one-to-one, one computer corresponds to one LED display or multiple computers in the local area network, corresponding to one display; the other is one computer Multiple LED displays or multiple computers correspond to multiple LED displays. In the case of forgotten IP addresses, many manufacturers' solutions are to let the user reset the factory settings, let the control system restore to the factory default IP address, or only one device at a time, this is only the first case. Well, there is only a single display, but when it comes to the second case, multiple display screens, the workload is very large, so the feasibility of these methods is very low, even restore the factory settings, you need to touch the hardware processing, if the screen The installation is high, the reset brings great difficulty to the user, and even if the recovery, including the control system setting information, remark information and other related content are cleared one by one, for users who are not very familiar will cause more and more Trouble, leading to a more chaotic situation. The following figure shows the structure of the management system of the LED display IP address.

As shown in Figure 1, the system includes a host computer 1 and more than one LED display control system 2, each LED display control system 2 is provided with an asynchronous control card 3, the upper computer 1 and each LED display control The asynchronous control card 3 in the system 2 is connected.

The asynchronous control card 3 is provided with a storage module 31. The storage module 31 stores an IP address, a subnet mask, a default gateway, a port number, a physical address, a master control information, and a master control address of the LED display control system 2. .
