为了准确获取实时的飞行参数,提出了一种以FPGA为核心的多路数据采集系统设计。描述了系统硬件设计,通过VerilogHDL语言设计有限状态机完成流水采样以及FPGA与DSP数据通信,并用Modelsim对各设计模块进行仿真。实验证明这种设计方法简化了系统的硬件电路复杂性,使整个采集系统具有灵活高效的特点。

In order to collect real-time flight parameters accurately, the design of a multi-channel data acquisition system was proposed using FPGA as the core. The system hardware design was described. Pipeline sampling and data communication between FPGA and DSP were both realized by Finite State Machine described in VerilogHDL, and the design modules were simulated by Modelsim. Experiment proved that this design simplifies the complexity of the hardware circuit and makes the data acquisition system possess a flexible and efficient characteristic.
