基于FPGA的燃烧动态监测系统设计

摘要

设计了一种基于FPGA的燃烧动态监测系统,介绍了该系统的硬件结构.该系统能够实现对燃烧室动态压力信号和加速度信号的实时采集、缓存、Blackman加窗、FFT变换和频域稳定性分析功能.此外该系统还可以通过PCIe接口将日常运行数据发送至上位机,由上位机保存到硬盘进行备份.最后通过仿真和硬件调试,验证了方案的可行性.%A FPGA-based monitoring system for dynamic combustion was designed and its hardware structure was introduced.The system can collect dynamic pressure signals and acceleration signals from the combustion chamber and can pre-store them,including implementation of Blackman window processing,FFT and stability analysis in frequency domain at real time.In addition,this system can has daily operation data uploaded to the upper computer through PCI express interface and then saved them to hard disk for backup.Simulation and hardware debugging verify the feasibility of this scheme.
