工作环境设置及软件安装这章介绍工作环境的设置及软件安装方面知识。为什么要进行工作环境设置呢？因为现在的PCB 工程师要设计的文件很多。文件多了如果不进行管理就会很混乱，导致以后的维护十分困难。所以要从刚开始学习的时候养成一个好的操作习惯，这是很有必要的。2.1 建立自己的工作目录在电脑的桌面上打开我的电脑，在我的电脑中打开D盘。在D 盘中建立三个文件夹。分别为“D：\EDA”“D：\EDA_LIB”“D：\EDA_PROJECT 三个文件夹”。如下图所示：图2-1-1 “建立工作目录”建立好三个文件夹后，在这三个文件夹中分别另建立一个新文夹，并命名为Protel99se。三个文件夹的作用分别是：EDA文件夹是用来存放安装文件；EDA—LIB 文件夹是用来存放元件库。EDA—PROJECT 文件夹是用来存放设计数据。2.2 对Protel 99se 进行安装设置好工作目录后，就可以对软件进行安装。图2-1-2就是Protel 99se的安装程序。其中“Protel99SP6”是升级补丁，“Protel99 汉化”是汉化文件。（1）双击Setup 安装图标对软件进行安装。

This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) PROJECT. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP PROJECT, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

便携式信号采集在机器健康诊断系统中有较高的应用价值。机器健康诊断的信号特点是包括低频信号。本文研究是为了实现简易而且低成本的低频便携式信号采集。以Microchip公司单片机PIC18F1320为核心设计信号采集电路，实现了信号的采集和保存。系统采用串行电可擦除芯片24LC32A保存数据，经过有线通信，信号数据由串行口通过MAX232芯片输送到微型计算机接收和保存，最后绘制出信号波形。 微型计算机程序采用Visual Basic编程。研究成功采样频率为3 kHz的复杂信号，证明该方案符合设计要求。 Abstract: Portable signal acquisition is useful in machine health monitoring systems. The signal characteristics of machine health monitoring includes low frequency signals. The goal of this study is to realize simple, inexpensive and portable low frequency signal sampling. This paper provides the PROJECT of signal acquisition system design based on PIC18F1320 microcontroller manufactured by the Microchip Technology Incorporation to achieve signal sampling and storage. The system adopted EEPROM 24LC32A to store the signal data. The microcomputer received data via wired link with the MAX232 IC through the serial port. The microcomputer program, programmed in Visual Basic, received the data, stored it and plotted the signal. The study successfully samples 3kHz complicated signals and thus meets the design requirement.
