摘要
在数字化测控及检测系统中,对现场各种信号源信息的获取主要由各种类型传感器及数据采集通道组成,系统的技术指标通常也由这两方面决定。主要就传感器输出及模拟输入A/D分辨率进行了辨析,对传感器与数据采集(即模拟输入A/D)的理性选型及合理匹配进行了简要分析,旨在达到降低系统误差,提高系统精度等级的目的,进而为系统准确度提供保证。
Different kinds of signals are acquired by sensors and DAQ channels which decide the technology parameters in digital measure and control system.This paper introduces the output of sensors and analog input A/D resolution.It also analyzes the selection and matching of sensors and DAQ.The purpose of this paper is to reduce the system error and improve precision to a certain extent.
