摘　　要：文中针对传统的采编存储设备的可靠性低,不利于硬接收,数据记录量小,传递速度低的问题,设计了以FPGA为主控模块,以LVDS为采编器与存储器的输送数据接口,以千兆以太网为采编器与地面设备的数据传输接口,以采编模块、数据传输、实时监测、存储单元为主要功能模块,采用Flash作为存储单元,合理选择存储的工作模式,按照标准化的设计思路,结合任务书要求进行设计,提出了基于FPGA的视频监测存储系统设计方案。实验结果表明传递数据最高错误率为0.1%,具有操作简易、抗高过载、集成度高、工作稳定的优点。In view of the traditional editorial storage equipment reliability is low,is not conducive to receiving,has small amount of data records and low pass rate,this paper designed FPGA as the master control module,LVDS as data interface of editorial and storage equipment,and gigabit Ethernet as data transmission interface of editorial and ground equipment,this paper designed editorial module,data transmission,real-time monitoring,storage unit as the main function modules,took Flash as the storage unit,chose the reasonable working mode of storage,according to the design idea of standardization,combined with the requirements of the task book design,a design scheme of video monitoring and storage system based on FPGA was proposed.The experimental results show that the highest error rate of transmission data is 0.1%.It has the advantages of simple operation,high overload resistance,high integration and stable operation.
