1、课程设计报告摩尔斯电码发声器课程设计报告Morse电码发声器 程序方案：0-9和A-Z的摩尔斯电码表如下图所示：将0-9和A-Z的摩尔斯电码制作为一个36行6列的二维数组，如下图所示当输入0-9或A-Z之间的字符时，程序会根绝具体的字符，从摩尔斯电码表的二维数组中选出对应该字符的一行数组输出，作为该字符的摩尔斯电码。用一个字节的二进制数代表一个字符的摩尔斯电码，左起第一个1为起始标志（起始标志及之前的0无效）。起始标志后的0表示点。起始标志后的1表示划。如：A 的报文信息 0000 0101B 的报文信息 0001 1000C 的报文信息 0001 1010按此规律建立一个报文信息表，报文信息

2、表要按 09 、AZ的顺序排列，发送时先查表找字符对应的报文信息，左移报文信息找起始标志，（起始标志及之前的0不发声），然后调用点划子程序发点划声响，发送一个字符循环8次则自动结束。报文信息表同样为一个36行6列的二维数组，如下图所示：系统细节方案：点划间隔子程序是通过调用window.h库中的Beep函数是系统发出声音。程序收到字符后，根据字符对应的摩尔斯电码表中的数组，输出该字符的摩尔斯电码，并且查找到该字符的01报文信息表，通过两个循环，调用点划子程序，完成电码的发音功能。子程序及其流程图：点声音程序代码： 点声音程序流程图int dot()/点声音 Beep(7000,200); re

3、turn 0;划声音程序代码： 划声音程序流程图int dash()/划声音 Beep(7000,600); return 0;点划之间间隔程序代码：int space()/电码间隔声音 Beep(0,400); return 0; 主程序详解：程序设计初期，用C+编写了一个控制台应用，先编写了一个电码编译的子程序：int tra(char c)/电码编译 if(c=48&c=57) coutc的摩尔斯电码是：mc-48endl; for(i=0;i8;i+) if(nc-48i=1) j=i+1; break; for(i=j;i=65&c=90) coutc的摩尔斯电码是：mc-65+10

4、endl; for(i=0;i8;i+) if(nc-65+10i=1) j=i+1; break; for(i=j;i8;i+) if(nc-65+10i=0) dot(); if(nc-65+10i=1) dash(); space(); else if(c57&c90) coutc输入格式错误，不是0-9或A-Z之间的字符endl; return 0;电码编译子程序流程图：在主程序中利用fstream库中的ifstream文件流又编写了一段可以打开文件的语句，主程序代码如下：int main()/主程序 while(1) cout请选择输入字符或者文件路径ch; if(ch=c)/输入字

5、符进行编括译 cout请输入0-9或A-Z之间的字符c; tra(c);/调用编码函 Sleep(500);/设置读取字符延迟 else if(ch=f)/输入文件路径进行编译 cout请输入文件路径filename; ifstream infile(filename,ios:in); if(!infile) cerr打开文件错误endl; while(infile.get(c) tra(c); Sleep(500);/设置读取字符延迟 else cout输入格式错误endl; 主程序流程图编译运行的结果：程序设计后期在windows窗体应用中创建项目，建立一个窗体，在窗体中完成字符、文件的打

6、开、编译功能，在窗体中添加控件，将之前的程序写入各个控件的动作中，完成程序的功能，程序运行结果如下图：在textBox1中输入字符，程序将textBox1中的字符存入指向字符数组的指针中，再根绝数组中字符，找到相对应的报文信息进行编译发声。利用openFileDialog打开文件，利用richTextBox中的LoadFile方法加载文件，再将richTextBox中的字符存入数组指针中，利用指针循环自加对数组指针中的字符进行编译发声。Morse电码主程序自动生成的cpp：/ morse.cpp: 主项目文件#include stdafx.h#include Form1.husing name
