摘要: 航空电气系统包括用电设备与供电系统。飞机供电系统在现代飞机系统中至关重要，保障着航空器飞行任务的顺利执行。随着机载用电设备数量的急剧增多，用电设备与飞机系统间的供电兼容性问题日益突出。供电兼容性试验的试验结果成为验证机载用电设备供电兼容性是否合格的依据。本系统基于NI LabVIEW开发环境，结合信号监测设备以及信号输出设备，设计用于机载用电设备电压畸变频谱的自动化测试系统。该测试系统可移植性良好，易于部署，交互界面简洁，能够提高测试系统的自动化水平。

Abstract: The aviation electrical system comprises electrical equipment and power supply systems. The aircraft power supply system plays a crucial role in modern aircraft systems, ensuring the smooth execution of aviation mission tasks. With the rapid increase in the number of onboard electrical equipment, the issue of power supply compatibility between electrical equipment and the aircraft system has become increasingly prominent. The results of power supply compatibility tests serve as the basis for verifying whether the onboard electrical equipment meets the power supply compatibility standards. Based on the NI LabVIEW development environment, this system integrates signal monitoring equipment and signal output devices to design an automated testing system for the voltage distortion spectrum of onboard electrical equipment. This testing system boasts good portability, easy deployment, and a user-friendly interface, enabling it to enhance the automation level of the testing process.
