资料介绍

介绍了以ARM内核S3C2440为处理器,24位自带模拟开关的ADS1256芯片为A/D转换和信号输入通道选择,利用其特性、工作原理来设计具有高精度、多通道、实时操作性强的地震数据采集系统电路。数据通过桥式低通滤波输入。有效地抑制了长导线共模信号,并且大大提高了整个电路抗电磁干扰能力,从而可以实现地震数据采集系统的高精度、高质量、低功耗和便携式等特点。

The circuit, which has high accuracy, multi-channel and strong real-time operational performance, and takes ARM kernel S3C2440 as its processor, and 24-bit ADS1256 chip with the analog switch as its A/D conversion and signal input channel, was designed for a seismic data acquisition system. The bridge low-pass filtering input of data effectively inhibits the common mode signal through long wire and greatly improves the ability of the whole circuit resistance against electromagnetic in- terference, by which the characteristics of high precision, high quality, low consumption and portability were realized for the seismic data acquisition system.
