摘要
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。
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.
