【摘要】 空气流量传感器是一个重要的发动机控制反馈元件,在发动机自身排放与控制等性能方面有着十分重要的影响。本文设计了传感器智能测试系统,通过小波变换对信号进行去噪处理,并对处理后的信号进行变换分析并对该系统的进行验证。实验结果表明,该系统能有效地提高空气流量传感器的性能和使用质量。更多还原

【Abstract】 Based on the application status of air flow sensor, this paper designs the sensor intelligent test system and verifies the system. Firstly, after the system is set up, the signal is de-noised by wavelet transform and the signal is transformed. Experimental results show that the system can effectively improve the performance and quality of the air flow senso.更多还原
