基于FPGA的飞机轮速测量系统设计

The Design of the Aircraft Wheel Speeds Measurement Based on FPGA

飞机机轮速度信号在飞机刹车过程中至关重要,随着航空业对速度采集标准要求的日益提高,对机轮速度信号的高精度,实时性,可靠性也提出了更高的要求。系统硬件以单片FPGA芯片为核心,采用状态机的思想来实现多路速度信号的采集。通过软件优化和反复验证,调试结果表明该系统运行可靠,满足设计。

The singals of the Aircraft wheel speed are very important in the brake process of the aircraft.As for the standards of data acquisition speed improved in aviation day by day the singals of the aircraft wheel speed are required higher precision.Also the real time and reliability are need to be improved.In this system we use the FPGA and DSP chip as the core of the hardware and adopt state machine to realize multiple signal collection.The application shows that this system runs stably and accurately and has been used in reality.
