Abstract


The process of modern civil aviation operation is an integrated systems engineering, the state of the airport project system is the important to impact the development of the aviation industry, the aviation aircraft DC power supply system is one of critical system to protect flight safety, so DC power system fault detection is an important research subject to airline power research. However, the complexity of the system structure, the difficultiy of fault model, and many fault parameters of sensor nodes can not obtain at the same time which brings much inconvenience to analysis of the system working parameters and faults.According to the disadvantage of traditional fault detection of aircraft DC power and the development trend of fault detection system ,this paper analyzes and fixes the detection points and modes of the airline DC power , makes the FPGA for platform to design the embed real-time fault detection system based on network. The system mainly designs the IP core of controller of A/D converter and FIFO which is to match the differency of data processing and data transmission. By programming peripheral drivers, operation system can identificate and manage peripherals. For data transmission part, the physical layer uses the plastic optical fiber, which is light-weight, anti-jamming, easy-bending, to improve system capability. Upper layer protocol use the TCP/IP to package acquisition data, the application layer uses Socket programming to communicate the detection system and host itself.
