汽车动态称重信号的两个处理方法
The Two Measurements of Signal Processing for Weigh-in Motion of Vehicle
【摘要】 利用周期性多项式拟合去除 0~ 30Hz低频噪声 ,基于参数估计进行轮重动态辨识 ,结果表明在 30km/h的实验车速时 ,对汽车动态称重信号处理的方法可使得轮重辨识精度达到国际参考标准ASTME1318- 94的要求 .
【Abstract】 The noise in frequency domain of 0~30 Hz is dismissed by using the optimization arithmetic to fit the low frequency periodic disturbing. Based on parameter estimation, the dynamic identifying of wheel load is carried out by math modeling mechanism of weigh-in-motion system. The identifying results meet the international standard ASTM E1318-94 at the test velocity of 30 km/h.
