【正文】 ng，this paper encapsulates some functions about serial portprogram and multipicture show designing，and tells general method of serial munication program and muhipicture show designing．This paper also gives method of realizing remote monitoring and controlling system．Key Words：Remote Monitoring；Visual C++；Objectoriented Serial Connunication Console ControllingRemote monitoring system to control camera head and foot system, an important function, it must be realized by means of serial programming, how to effectively develop serial munication program, full remote monitoring system based on software, the key link. In this paper, objectoriented programming, using Visual C + + implementation monitoring system control and multihead screen Kenji function. 1..A remote monitoring system structure According to features of different hardware and connections, remote monitoring system can be divided into two types: bus type, star, star extended. One star is the most widely used, is the most economical one, the connection method shown in Figure 1. Using satellitebased remote monitoring system is characterized by foot: (1) of the lens can be two variable control: control of aperture, focal length, lens stretching。 (5) coding relentless twoway munication codec: encoder and decoder with separate address code, used for addressing the digital signal, it can be the appropriate feedback information and alarm information back to the main control system can achieve oneway remote control。 lpBuf for storing the data to write buffer, dwCount for the number of bytes to write. (3) Reading serial port: DWORD ReadPort (void * lpBuf, DWORDdwCount)。 cmd [O] = Oxfc。 / / basketry and head directly connected to a constant value cmd [4] = PtcAddr。 }④ close the serial port: m_Port. ClosePort0. 3 remote onitoring system to achieve multiscreen display For remote monitoring systems, multiscreen display is an essential function. And traditional surveillance systems different enough: multiimage was not seeking the help of hard even to achieve, but enough to finish entirely by software. Objectoriented programming idea of this article defines a class CPicView, through it can easily achieve these functions, and can greatly increase the scalability of the software. To the main class of the CPicView interface functions briefly. (1) initialization: BOOL Ini。 / / control head to the left cmdl6] = Oxl00((cmd [O] + cmd [1] + cmd [2] + cmd [3] + cmd [4] + cmd [5])% Oxff。 cmd [2] = EricordAddr。 ② beat Ji serial: m_Port. OpenPort (1,9600, CComPort:: NoParity)。 in receiving data, the serial data bits are converted to bytes. In the Windows environment, the serial port as part of full system resources. Applications to municate using the serial port must be provided to the operating system prior to coop required to open the serial port, munication port must be closed after the release of resources. In actual programming, just as mining and flow control means of munication is not, serial settings are different, this involves the initialization and read and write serial DCB details of the problem, DCB (Device Control Block) structure defines the serial munication device control settings, a number of important settings in the Ministry is done in this structure. In objectoriented programming, class implementation is the core issue, keep the serial port can operate the function with the package as a class: CCorePort. Fabric program as long as Lu Ming An example of a CComPort be on the serial port after the operation. Following on the CComPort several members of the class of the most monly used functions briefly. (1) Open the serial port: void OpenPort (int nPort, DWORD dwBaud = 9600. Parity parity NoParity. BYTE DataBits = 8, StopBits stopbits = 1, FlowControl fc = NoFlowControl, BOOL bOverlapped = FALSE)。 (3) can simultaneously display multiple channels of video information。采用此方法編寫的遠程監(jiān)控系統(tǒng)已投入使用，實地運行結果表明，系統(tǒng)可實現(xiàn)對云臺的上、下、左、右轉動全方位的控制和多畫面顯示功能，特別適用于監(jiān)控對人體有毒、有害的作環(huán)境，而且真正實現(xiàn)了少人或無人看管，減輕了現(xiàn)場工作人員負擔，降低了工程造價，提高了經(jīng)濟效益。(4)設置某一通道為當前畫面：BOOL SetCufDentView(int index)；參數(shù)index為要設置的當前畫面，基數(shù)為0：在整個系統(tǒng)的控制面板上只有一個當前畫面，控制功能只對當前畫面起作用．且只有當前畫面可進行聲音預覽。以對CPicView類的主要的接口函數(shù)進行簡要的說明。)④ 關閉串口：m_Port．ClosePort0。 //編器和云臺直接相連，值恒定為1cmd[4]=PtcAddr。cmd[O]=Oxfc。(3)讀串口：DWORD ReadPort(void* lpBuf,DWORDdwCount)；lpBuf為存放要讀取數(shù)據(jù)的緩沖區(qū)，dwCount為要讀取的字節(jié)數(shù)。布程序中只要盧明一個CComPort的一個實例后便可對串口進行操作。在Windows環(huán)境下，串口足系統(tǒng)資源的一部分。遠程監(jiān)控系統(tǒng)中控制功能有控制鏡頭和控制云臺，它須借助于串行通信來實現(xiàn)。同時編碼控制提高了設備控制的可靠性，使布線、維修較為容易。本文采用面向對象的編程方法，利用Visual C++實現(xiàn)監(jiān)控系統(tǒng)的云臺控制和多畫面顯爾功能。對有關串口編程和多畫面顯示的函數(shù)進行了類的封裝。 } (12,bytXor)。 bytXor=0。 return。 } }}else{//發(fā)送設備操作命令if(m_Address==0 amp。i++) { bytXor=(i)。 (11,0x80)。 }}//根據(jù)iType發(fā)送具體的命令if(iType==40100){(“選擇設備地址！”)。 { (“無操作！”)。 Updatedata(false)。 bytCommand=0x97。 break。 } case 10400。 { (“無操作”)。 Updatedata(false)。 bytCommand=0x93。 break。 } case 10200。 { (“無操作”)。 Updatedata(false)。 BYTE bytXor=0。6 致謝畢業(yè)設計即將結束，感謝我的指導老師吳力普老師。程序流程圖要從大塊做起，然后一步一步細化，越細化越好，編寫軟件的時候要從小塊編起，從一個個子程序環(huán)節(jié)編制，確保每個子程序之間相對獨立，做好出口入口的標志位影響工作，然后再結合到一起進行聯(lián)調。本系統(tǒng)涉及到的原理性知識比較多，對各個知識點的明晰是非常有必要的，每個模塊的功能，各個模塊之間的通訊方式，通訊連接，在功能完備的基礎上，還要考慮安全穩(wěn)定方面的設計，因此在原理概念上一定要明晰。，設計云臺操作控制臺所應具有的基本功能。只有計算機向解碼器的發(fā)送數(shù)據(jù)操作，而沒有計算機從解碼器接收數(shù)據(jù)的操作。因此，本程序是用picture靜態(tài)圖片框來模擬按鈕的操作。 初始化操作 初始化包括對成員變量的初始化及控件的二次創(chuàng)建等操作。選擇設備，打開和關閉雨刷，打開和關閉射燈等操作?？梢栽O置使用的串口號碼，從COM1~COM6。雨刷控制變量賦0雨刷控制變量賦1數(shù)據(jù)發(fā)送流程YN雨刷控制返回雨刷是否正在工作 數(shù)據(jù)發(fā)送程序。 開始程序初始化地址波特率設置按鍵觸發(fā) 主程序軟件流程圖 運動控制流程 。由于Visual C++的這些優(yōu)勢，所以此次選用了此開發(fā)工具。 這些組件通過一個名為Developer Studio的組件集成為和諧的開發(fā)環(huán)境。雖然微軟公司推出了Visual C++.NET(Visual C++)，但它的應用的很大的局限性，只適用于Windows 2000，Windows XP和Windows 。 不同時代的控制系統(tǒng)產(chǎn)生出不同的控制
