Testing Device for Data Communication Capability of RS422 Interface in Aerospace Software
【摘要】 为了保证基于RS422接口的软件数据通信能力,介绍了一种测试装置。该装置以FPGA测试板卡(下位机)与计算机(上位机)相结合,通过调节波特率、通信数据帧格式、通信数据包之间时间间隔等,实现型号软件数据通信能力的检测。
【Abstract】 In order to guarantee the capability of the data communication of software based on RS422 interface, a testing device is introduced. The device consists of a FPGA card(slave computer) and computer(master). The detection for the data communication capability of aerospace software with RS422 interface is realized by adjusting the baud rate, data frame format and time interval in data packets.
