摘要
为了有效地进行列车司机驾驶疲劳实时检测,利用ADI公司的双核DSP芯片ADSP-BF561,设计了车载的嵌入式列车司机驾驶疲劳在线检测系统。阐明了该嵌入式系统的硬件组成原理和PERCLOS非接触式疲劳检测方法,最后详细阐述了系统软件结构和设计实现方法。实验结果表明此方案能实时检测疲劳发生,该系统体积小、成本低、实时性好。
In order to do effective,real-time detection of the train driving fatigue,a vehicle-mounted embedded train driving fatigue detecting system is designed taking ADI dual-core DSP chip ADSP-BF561 as a core.The hardware components principle of this embedded system and PERCLOS,a non-contact fatigue detection method,are clarified.Finally,the structure,design and implementation methods of the system software are elaborated in details.The results show that this design scheme can detect fatigue in real time; the system has small size,low cost.
