Embodiment Construction

[0022] The invention is a 100M Ethernet LED display control system, and the data transmission between modules in the system all adopts the 100M Ethernet transmission mode. The protocol of Ethernet includes physical layer protocol, data link layer protocol and network layer protocol. Considering the characteristics of real-time transmission and the complexity of system design, when applying 100M Ethernet to the LED display control system, the present invention only uses the physical layer protocol of 100M Ethernet. The design of the 100M Ethernet LED control system involves the design of the transmission part of the system controller and the design of the transmission part of the module controller. The control system is composed of a system controller and a module controller. The FPGA of the system controller is connected with multiple 100M Ethernet interfaces to realize the control and send and receive data of the Ethernet interfaces. Each 100M Ethernet interface is independe...

Abstract

The invention relates to an Ethernet type LED display screen control system which is characterized in that 100M Ethernet technology is drawn into an LED control system so that the data transmission in the interior of the whole system is transmitted in a 100m Ethernet mode and the whole control system is more flexible and convenient to use and particularly suitable for occasions with special requirements. The control system adopts physical layer protocol of 100M Ethernet; the control system comprises a system controller and a module controller; the system controller comprises a plurality of independent 100 M Ethernet interfaces; each 100 M Ethernet interface is independently controlled by a field programmable device; the model controller comprises two network interfaces, an IN port for receiving data and loading autologous field programmable device and an OUT port for transmitting data to a module controller of next level.

Description

1. Technical field: [0001] The invention relates to an LED display screen control system, in particular to an Ethernet-type LED display screen control system, which is an LED display screen control system transmitted by Ethernet. 2. Background technology: [0002] With the popularization of electronic display applications and the improvement of people's quality of life, in many fields people are no longer satisfied with displaying simple text and graphic information on offline displays, and hope that offline displays can also play high-quality, large-size images And video information, and at the same time put forward higher requirements for the refresh rate and frame change frequency of the display screen. In order to meet these requirements, the LED display control system is divided into several modules according to functions, such as: system controller module, module controller module. An LED display control system consists of a system control module and several module co...
