针对实测信号微弱、频变、窄带的特点,设计出低噪声、窄通频带、高精度的数据采集滤波电路,有效地滤除了干扰和噪声,使系统探测精度达到±0.3m左右;根据磁感应强度数据的采集要求,制定了单组数据校验的通信协议,减少了干扰导致的个别数据传输错误对整体数据的影响。
針對實測信號微弱、頻變、窄帶的特點,設計齣低譟聲、窄通頻帶、高精度的數據採集濾波電路,有效地濾除瞭榦擾和譟聲,使繫統探測精度達到±0.3m左右;根據磁感應彊度數據的採集要求,製定瞭單組數據校驗的通信協議,減少瞭榦擾導緻的箇彆數據傳輸錯誤對整體數據的影響。
침대실측신호미약、빈변、착대적특점,설계출저조성、착통빈대、고정도적수거채집려파전로,유효지려제료간우화조성,사계통탐측정도체도±0.3m좌우;근거자감응강도수거적채집요구,제정료단조수거교험적통신협의,감소료간우도치적개별수거전수착오대정체수거적영향。
For the measured signal is weak,the frequency change,narrowband characteristics,design a low noise, narrow band pass,high-precision data acquisition filter circuit,effectively filter out the interference and noise,allowing the system to detect accuracy of about±0.3m;based on magnetic induction the data collection requirements to develop a single set of data validation communication protocol reduces the impact of individual data transmission errors due to interference on the overall data.
