摘要
对基于CAN总线的星载软件测试系统设计进行了研究。系统硬件包括PXI工控机和CAN高速板卡,应用LabVIEW编程模拟各下位机,实现了与星载软件的通信,具有下位机的状态检测、遥测数据分析、注数数据监测和计算机内存下卸等功能。实际应用表明:该基于CAN总线的星载软件测试系统满足第三方测试要求,运行稳定可靠。
The design of satellite onboard software test system based on CAN bus was studied in this paper. The test system was composed of PXI IPC and CAN high-speed card. It was simulated using programming by LabVIEW software. The test system realized the functions of status testing, telemetry data analysis, injection data monitor, computer internal memory download and etc. The application results showed that the test system could meet the test requirement by the third party, which had good performance of stability and reliability.
