摘　　要：针对岩土工程对现场数据采集的精度和速度提出了更高的要求，该文以S3C4480处理器为核心，辅vY,必要的外围电路，设计了一种上位机监控的多路数据采集器。采用ADS8505芯片进行AD数据采集，达到16位的精度；采用电子开关CD4067芯片扩展输入通道，实现了16路信号的数据采集；通过RS-485方式与PC机进行数据通信，实现上位机对采集器的控制和数据的处理显示．进而设计出了高精度、高分辨率、多通道的数据采集系统。Meeting the higher request in precision and speed toward data acquisition for geotechnical engineering, this paper taking the S3C44B0 processor as the core and adding the necessary peripheral circuit, design a kind of PC monitoring of multi-channel data acquisition unit. Using ADS8505 for AD data acquisition, reach 16 bit accuracy; Expand input channel by using CD4067 which is an electronic switch, realize the 16 channel signal acquisition; Communicate with PC through RS-485 so that upper computer can control it and data can process and display, then design a data acquisition system with high accuracy, high resolution and multi-channel,
