Design of helicopter vibration signal monitoring system based on FPGA
直升机因优越的灵活性和机动性在军事、民用和民生领域得到广泛使用,并且在特定领域具有不可替代的地位.文中针对传统直升机故障检测虚警率高问题,基于 EP4CE系列 FPGA 芯片利用12位8通道模/数转换芯片ADC128S022实现对直升机振动数据的实时采集,将采集数据进行快速傅里叶变换(Fast Fourier Transform,FFT)并提取特征值分析.实验结果表明,系统对直升机故障检测报警准确率高达99%以上.
Helicopters are widely used in military,civilian,and public sectors due to their superior flexibility and maneuverability,and they hold an irreplaceable position in specific fields.To address the high false alarm rate in traditional helicopter fault detection,this study utilizes the EP4CE series FPGA chip and a 12-bit 8-channel analog-to-digital converter chip ADC128S022 to achieve real-time ac-quisition of helicopter vibration data.The collected data is processed using the Fast Fourier Transform(FFT),and feature values are extracted for analysis.The experimental results demonstrate that the system achieves an accuracy rate of over 99%in helicopter fault detection and alarm.
