QPSK rayleigh channel matlab modeling and simulation

用S7-200PLC的自由口模式和VB中的MSComm控件方便地实现了计算机与S7-200（CPU224）PLC的通讯。计算机作为主站,用户通过计算机可以方便地设置房间的控制指令并向PLC发出控制或监测命令， PLC作为从站来响应计算机发送的指令并采取相应的动作并将房间的电、水、热信息发回到计算机。用户可以通过电脑屏幕实时地监视到房间的电、水、热信息并进行相应的处理。-with S7-200PLC the Free Port Mode and the VB MSComm to realize a trap Computer and S7-200 (CPU224) PLC communications. Computer as a master station, Computer users can easily set up control rooms PLC issued directives to control or monitoring orders, PLC as from the station to respond to orders sent by the computer and take corresponding action will be room for electricity, water, Heat fat information to the computer. The user can screen real-time surveillance of the room electricity, water and heat information and handled accordingly.

串口开发的另一种方式 最近在整理文件的时候发现了原先写的一个串口程序，为了提高重用性就又重新的写了一下。根据以前的使用过的一系列串口操作软件发现，大多数的串口操作软件不具备自动的记录保存功能，于是我就在这里把它加进去，记录文件是在应用程序目录下以时间命名的文本文件。程序使用了两个可以重用的 C++ 类，串口通讯类文件 superSP.cpp, superSP.h 文件操作类文件 fileCtrl.cpp, fileCtrl.h。 -development in a different way recently in the collation of the documents identified a previously written a serial process, In order to improve reusability also on the re-write a bit. Under the previous use of the series of Serial operating software found, Most of the serial operating software does not have an automatic record-keeping functions, so I was here it added. documented in the application directory time to a text file named. Procedures for the use of the two can reuse the C category, serial communications superSP.cpp document, superSP.h file manipulation fileCtrl.cpp types of documents, fileCtrl.h.

MTP3层测试程序-ATM layer testing procedures

约简单的说就是指在电力系统中,发送信息端与接受信息端对所发送数据的报文格式封装与解封装的一套约定。为了实现规约的标准化,国际电工委员(International Electrotechnical Commission)制定了一系列的远动规约的基本标准,并在此基础上制定了基于TCP/IP协议的IEC 60870-5-104国际标准,用以对地理广域过程的监视和控制。
