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 the development of aviation technology, a large number of airborne equipment, especially aeronautical instrumentation and transmission systems, are driven by electric energy, and the role of aviation power supply in modern aircraft becomes more and more important. As the power hub between aircraft generators and airborne electrical equipment , The reliability of aircraft secondary power is of great significance for maintaining the stable operation of electrical equipment. The application of BIT technology can realize the real-time monitoring of the operating status of aircraft secondary power supply. However, the false alarm problem has caused a great deal of application of BIT technology Of the aircraft; for a type of aircraft secondary power supply using a reasonable hardware design combined with effective detection algorithm can significantly improve the false alarm rate of BIT system, which allows the operator to accurately grasp the working status of the aircraft secondary power supply, timely detection of problems , Reduce losses.
