Description: 利用SPCE061A，RS485 多路数据采集系统
本系统采用双CPU控制，主机与从机的CPU都是使用SPCE061A单片机。从CPU负责采集七路数据，同时应答主CPU发送的命令。主CPU进行数据处理，数据显示，键盘输入，系统报警，语音播报通道的电压值。在主CPU与从CPU的通讯中，采用国际标准的RS485差分方式接口，使通讯的速率和传输距离均大于RS232的标准接口方式，并且用线最少（只要两根）。本系统实现了一种具有语音播报、语音提示的高性能、高智能的实用型远距离多路数据采集系统。-The use of SPCE061A, RS485 multi-channel data acquisition system using dual-CPU of the system control, the host machine s CPU from SPCE061A Singlechip use. From the CPU is responsible for collecting data on seven routes, while answering the main CPU to send commands. The main CPU for data processing, data display, keyboard input, the system alarm, voice broadcast channel voltage. In the main CPU and the communications from the CPU, using international standards, the way RS485 differential interface to enable communication rate and transmission distance were greater than the standard RS232 interface mode, and with lines at least (as long as 2). The system achieved a voice broadcast, voice prompts, high-performance, high intelligence, practical long-range multi-channel data acquisition system. Platform: |

Description: 基于LabVIEW的多通道数据采集系统的设计,江苏科技大学硕士毕业论文。全文分为2部分第一部分数据采集硬件的设计中，采用DSP 作为采集卡的CPU，利用USB 接口实现了采集卡与PC 机的通信，整个外围逻辑时序部分用CPLD 控制。第二部分数据管理与分析，作者利用LabVIEW 编写了基于Windows XP的上位机应用程序以及上位机与采集卡之间的通信程序；利用LabSQL 工具包建立了ACCESS 数据库，实现对采集到的数据的存储，并可以查询历史数据。同时系统可以生成报表以及可以对所需要的数据进行打印，并可以对得到的数据进行一些必要的分析，如加窗函数，逐点分析。本文版权归作者所有！下载后产生后果下载者个人负责-LabVIEW-based multi-channel data acquisition system, Jiangsu University of Science Thesis. Paper is divided into two parts the first part of data acquisition hardware design, acquisition card with DSP as CPU, USB interface using a capture card and PC-communication, the entire outer part of the logic timing control with the CPLD. The second part of the data management and analysis, the authors prepared using LabVIEW Windows XP-based PC applications and PC and the communication between the acquisition card program use LabSQL Kit ACCESS database was established to achieve the collected data storage and can query the historical data. At the same time the system can generate the required reports and data can be printed, and can get the necessary data analysis, such as windowing function, point by point analysis.

Description: This document will describe some of the general usage of MATLAB s Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire
data from sensors and to send out electrical signals that can be used to control or
drive external devices. We will be using this toolbox with two different pieces of
hardware. One is the sound card built into your laptop, the microphone and speaker
will serve as the data acquisition (and output) devices. The sound card provides
convenience because it will allow you to test the DAT outside of the lab. We will
also be using Measurement Computing data acquisition cards that will ¯ t into your
laptops PCMCIA slot, these devices will be in the class laboratory. The data acquisition (DAQ) cards allow your computer to acquire data from many different types
of sensors. Platform: |
