基于FPGA与DSP的发动机参数采集系统设计

介绍可编程逻辑器件（FPGA）与数字信号处理器（DSP）在航空发动机参数采集系统中的应用研究。文章以EP4CE115F23I7可编程逻辑器件与TMS320VC5416数字信号处理器为核心设计、开发发动机参数采集系统。采用模块化设计，根据电路功能将发动机参数采集系统硬件分解为AD信号采集模块、通讯模块、离散量控制模块、数据处理模块以及参数记录模块。FPGA软件方面采用应用广泛的VERILOG语言，DSP软件采用C语言与汇编语言混合编程。并将发动机参数采集系统成功应用于某型直升机，效果良好。

The Design of Engine Parameter Acquisition System Based on FPGA and DSP

This paper introduces the application and research of programmable logic device (FPGA) and digital signal processor (DSP) in aero-engine parameter acquisition system. The engine parameter acquisition system is designed based on EP4CE115F23I7 programmable logic device and TMS320VC5416 digital signal processor. The hardware of the engine parameter acquisition system is decomposed into AD signal acquisition module, communication module, discrete quantity control module, data processing module and the parameter record module. FPGA software uses a wide range of VERILOG language, DSP software using C language and assembly language mixed programming. The engine parameter acquisition system is successfully applied to a certain type of helicopter, and the effect is very good.
