A fast search and connection method based on display screen control system

Abstract

The invention relates to a quick search connection method based on a display screen control system. The quick search connection method based on the display screen control system comprises the following steps of (i) receiving a broadcasting search package from a server; (ii) judging whether a user and a server side are positioned on the same network segment or not according to the received broadcasting search package; (iii) transmitting a first broadcasting replying package to the server side and trying to be in contact with a TCP / IP (transmission control protocol / internet protocol) established in the server side by using an IP (internet protocol) address in an old IP parameter if the user and the server side are positioned on the same network segment; and (iv) acquiring available IP parameters which are in the network segment of the server side according to the broadcasting search package if the user and the server side are not positioned on the same network segment, correcting the old IP parameters into the available IP parameters if the available IP parameters are acquired successfully, transmitting a second broadcasting replying package to the server side after the IP parameters are corrected successfully and trying to be in contact with the TCP / IP established in the server side by using an IP address in the corrected IP parameters.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a fast search and connection method based on a display screen control system. Background technique [0002] In the cluster management application of the LED display screen, the LED display control system and the cluster management terminal are connected through the network, so there are two ways in terms of network data transmission, one is UDP (User Datagram Protocol, user data Protocol) communication, one is TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) communication. [0003] Since UDP communication itself is connectionless and there will be network packet loss during data transmission, TCP / IP network communication is generally used. However, before TCP / IP communication, a connection needs to be established between the server (Server) and the client (Client) through IP, so independent TCP / IP communication wil...

AI Technical Summary

Problems solved by technology

[0004] (1) If the IP of the display control system cannot be determined, the display control system cannot be connected and configured;

[0005] (2) Once a problem occurs during the use of the display control system, if the IP of the display control system cannot be determined, the corresponding connection cannot be established, and the problem cannot be found, which will have a great impact on customers

[0006] In the prior art, in order to solve the problem that TCP / IP cannot establish a connection when the IP cannot be determined, nor can it configure the display control system and control the playback content through TCP / IP, the current existing solution is: establish a TCP Before the connection between the / IP server and the client, the server sends a UDP broadcast search command. If the display screen control system receives the broadcast search command (or non-broadcast search command) from the server, it tries to establish a connection with the server. The TCP / IP connection at the end, the specific process is as follows figure 1 shown

[0007] However, when the display control system receives the UDP broadcast search packet from the server, the display control system (TCP / IP client) establishes a connection with the server. If the server and the client are not in the same network segment, still cannot establish a connection, configure the display or control playback
