該系統以空氣中超聲波的傳播速度為確定條件,利用反射超聲波測量待測距離。The factors include ultrasonic wave frequence, condition temperature, ultrasonic converter instrinisic system error, hareware extended time, electricity noise and sonic noise in the spot, city power defmcient pressure and exceeded pressure, city power peak and pour. we adopt the following compensation schemes of error in the system. about ultrasonic wave frequence ' s effect to measurement precision, we can choose appropriate frequence according to the measured distance
在空氣和液壓缸中影響測距精度的主要因素包括:超聲波的頻率、環境溫度、超聲換能器本身的系統誤差(即探頭固定誤差) 、硬體時間延遲、工作現場的電噪聲和聲噪聲、市電的過壓、介壓噪聲以及市電的尖峰和浪涌噪聲,在本系統中採取了以下幾種誤差的補償方案: ?對于超聲波的頻率對測量精度的影響,只能根據測距的距離選擇合適的超聲頻率。
