Abstract
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S3C44b0处理器为核心,辅以必要的外围电路,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.
