摘　　要：为提高存储测试系统的实时性和稳定性,并考虑到数据量较大和数据存储安全的特点,设计了一种新型无线数据传输系统。该系统采用FPGA+W5100架构的以太网接口设计方法,外围电路采用NAND Flash存储器来作数据备份,引入了片外存储坏块地址的方法对Flash的坏块进行检测,并给出了系统的结构组成、硬件连接和软件实现方法。该系统增强了数据存储安全性,满足了远程和复杂环境下数据通信的要求。In order to improve the real-time and stability of the storage test system, and to take into account the large amount of data and the security of data storage, a new wireless data transmission system is designed. The system adopts Ethernet interface design method of FPGA＋W5100 architecture, the peripheral circuit using NAND Flash memory for data backup method introduces the external memory address of the bad block on Flash bad block detection, and gives the realization method of system components, hardware connection and software. This system enhances the security of data storage and meets the requirements of data communication in the remote and complex environment.
