Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The embodiment of the present invention proposes a UDP+TCP / IP mixed communication method in a local area network in order to improve communication efficiency, enhance communication stability and user experience when realizing the communication between the LED display control card and the host computer through the network cable.

[0022] Such as figure 1 As shown, the upper computer such as a PC can be directly connected to the LED display control card through a network cable, or can be connected to the LED display control card through a router or switch; that is, the LED display control card and the upper computer are connected through Ethernet. communication. In this embodiment, the Ethernet communication mechanism between the...

Abstract

The invention relates to an implementation method for performing Ethernet communication with an LED display control card. The method includes the following steps: (a) an upper computer searches an LED display control card located in a same local area network as the upper computer through UDP broadcast, so as to obtain the IP address and unique identifier of the LED display control card in the local area network; (b) the upper computer uses a system PING command to judge whether the IP address of the target LED display control card can establish a TCP / IP communication connection according to the acquired IP address of the LED display control card; and (c) the upper computer selectively communicates through a TCP / IP protocol or in the form of a UDP broadcast according to a judgment result and the target LED display control card. Thus, the implementation method can solve the problem that an IP address needs to be set when a user operates the LED display control card, and can solve the problem that when the LED display control card and the upper computer are located in the same local area network but IP addresses are on different network segments, normal communication cannot be performed.

Description

technical field [0001] The invention relates to the technical field of Ethernet communication, in particular to a method for realizing Ethernet communication with an LED display control card. Background technique [0002] In the LED display control system, the control card is typically connected to the host computer (such as a PC) through a network cable. When the control card and the host computer establish communication through the network cable, the host computer needs to obtain the IP address of the control card first, and judge whether it is the same network segment. addresses are in the same network segment. Afterwards, during data communication, the upper computer establishes a TCP / IP protocol connection with the control card, and communicates with the control card through the TCP / IP protocol. [0003] Therefore, it is necessary to solve the problem that the user needs to set the IP address when operating the control card, and solve the problem that the control card...
