摘要
为了解决同步LED显示控制系统大流量实时数据的采集、接收等[1]问题,将DVI接口技术与高速千兆以太网技术应用到同步LED显示系统数据采集与发送模块设计中,并通过显示系统的帧率、色彩分辨、像素长宽等信息对实际需要的信号带宽给予计算分析,提出以FPGA为系统核心部件、用显卡的DVI接口作为数据源、以高速千兆以太网进行实时显示数据的传输的设计方案,最后给出实际测试结果。结果表明,该模块满足同步LED控制系统对实时数字像素信息传输的要求。
In order to solve the problems of the large volume of real-time data acquisition and transmission of the synchronous LED display control system,the technology of DVI interface and gigabit Ethernet was applied.And the signal bandwidth needs were put forward by calculating and analyzing.The design for the system with FPGA as the core part,DVI interface of vedio card as data sources was presented and high-speed gigabit Ethernet technology was used for real-time display data transmission,finally the practical test results were given.Results show that the module of control system meet the synchronous LED real-time digital pixel information transmission requirements.
