摘　　要：针对工业领域中高速图像数据有效监测困难以及传统测试系统测量模式单一的问题,设计了一种以FPGA控制芯片为核心,以千兆以太网为数据存储与实时监测的接口,以FLASH为存储单元,合理选择存储模式,结合任务指标要求,提出了高速交叉模式接收存储千兆以太网数据并与PCM数据存储系统方案,该系统可将高速图像数据与音频数据传输并存储至上位机。测试与数据分析结果表明数据存储误码率为0,存储容量为16 GB,具有操作简单、性能稳定等优点。Aiming at the problems of the difficulty in the effective monitoring of high-peed image data in the industrial field and the single measurement mode of the traditional test system,a kind of storage mode was designed,which took FPGA control chip as the core,gigabit Ethernet as the interface of data storage and real-time monitoring,and FLASH as the storage unit.A high speed cross mode receiving and storing gigabit network data and combining with PCM data storage system was proposed.The system can transmit and store high speed image data and audio data to the master computer.The test and data analysis results show that the data storage error rate is zero,and the storage capacity is 16 GB.It has the advantages of simple operation and stable performance.
