摘要
本文根据某机载数传设备各SRU电路特性、接口通信协议,给出了基于SOPC的某机载数传设备板级检测的硬件电路模块和软件设计方法。利用生成多项式提取设备和各SRU输出的三线制长数据串的特征值,并实现了基于NiosII的UART与PC机进行串行通信,从而达到了该设备板级故障自动检测的目的。通过测试,该系统具有速度快、可靠性高等优点。
This paper presents the hardware circuit based on FPGA which realizes the SRU test of an airborne data transfer device,also the method of software design is given after the equipment＇s circuit characteristics and the interface communication protocol of the SRU are analysed.Long string of data is identified using generating polynomial,also the serial communication between the PC computer and the UART based on Nios II is successfully realized,therefore,attaining the purpose of automatic SRU test of the device.The testing results show that the system has the advantages of quick speed and high reliability.
