基于凌阳61板的数据采集系统的研究
摘要
数据采集系统是指将温度、压力、流量、位移等工业现场的各种物理量通过传感器变为电信号,经过放大、A/D采样转为数字量后,由计算机进行存储,处理、显示或打印的装置。数据采集系统由传感器、模拟信号调理电路、数据采集电路三部分组成。本设计主要是针对模拟信号调理电路、数据采集电路的设计。
本系统是以台湾凌阳公司生产的16位单片机SPCE061A为核心部件组成的一个简单的数据采集系统。该系统的主要部件有:SPCE061A、74LS164、LED、MIC、74HC244、SPY0029A、SPY0030(其中以S开头的器件均为凌阳公司产品)。SPCE061A是一款16位的单片机。
本系统不但能对单路信号进行采集,而且还可以对多路信号进行循环采集,最多可采集4路。在改变线性化程序的前提下,既可以采集温度信号,也可对压力、流量等信号进行采集。

Data Acquisition System
Abstract
Data acquisition system refers industry scene and so on the temperature, pressure, current capacity, displacement each kind of physical quantities(simulated signal) es through the sensor the electrical signal, again passes through A/D carries on the sampling to transfer the digital quantity, carries on the memory by puter, processing, the demonstration or the printing installment. The data acquisition system by puter, processing, the demonstration or the printing installment. The data acquisition system by the sensor, the simulated signal recuperation electric circuit ,the data acquisition electric circuit three parts posed. Our design mainly is aims at the data acquisition electric circuit the design and the simulated signal recuperation electric circuit
This system is insults 16 monolithic integrated circuit SPCE061A take Taiwan which the pany produces as a simple data acquisition system which the core poses. This system ponent includes: SPCE061A , 74LS164 , LED,MIC , 74HC244 , SPY0029A,ponent which begins by S for insult pany product). SPCE061A was design 16 monolithic integrated circuits.
Not only this system can carry on gathering to the single-channel signal, moreover has also been possible to carry on circulation gathering to the multi-channel signals most may gather 4 groups. Namely may gather the temperature signal, simultaneously changes the linearized procedure also to be possible to the pressure, the current capacity equisignal to carry on gathering.
Key words: Data acquisition ; SPCE061A; Memory
