摘要 随着航空技术的发展,大量机载设备特别是航空仪器仪表与传动系统采用电能驱动,航空电源在现代飞行器中的作用愈发重要;作为飞机发电机与机载用电设备之间的电力枢纽,飞机二次电源的可靠性对于维持用电设备的稳定运行具有重要的意义;应用BIT技术可以实现对飞机二次电源运行状态的实时监控,然而虚警问题对BIT技术的应用造成了很大的困扰;针对某型飞机二次电源采用合理的硬件设计结合有效的检测算法可以显著改善BIT系统的虚警率,这就使操作人员能够准确掌握飞机二次电源的工作状态,及时的发现问题、减少损失。 With a large number of airborne devices powered by electric energy such as aviation Instrumentation and transmission system, the role of electric power in modern aviation aircraft is becoming increasingly important. As the hub between power generator and airborne e- lectrical devices, the reliability of aircraft secondary power supply for electrical equipment stable operation is of great significance. Apply the BIT technology can monitor operating state of aircraft secondary power supply in real--time, however false alarm problems for the application of the BIT technology caused a lot of trouble. For a type of aircraft secondary power supply using reasonable hardware design combined with effective monitoring algorithms can significantly improve false alarm rate of BIT system. Whereby the operator can get the operating state of aircraft secondary power supply, to identify problems in time and reduce losses.
