【正文】 loatingpoint processor TMS320F28335 is selected as the DSP, which possesses excellent dataprocessing performance and be rich of onchip peripherals. The type of FPGA is EP2C8Q208CN, which is of large mount of onchip logic elements and cost effective. The core controller DSP is in charge of mission flow control, task allocation and system harmonization which mainly includes algolithm operation, missions dispatch, ethernet munication etc. The obligations of FPGA are to extend interfaces with peripheral functional modules such as feedback signal input, control signal output, data latching. In addition, FPGA can receive data process mission from DSP and be implanted digital signal processing IP cores while some plex algorithms operation in need.The system software consists of real time monitoring module, background dataprocessing module, network service module. They three are not only closely interrelated but also relatively independent. Network service module is the bridge of the munication between local dataacquisitionamp。關(guān)鍵詞：網(wǎng)絡(luò)化；信號(hào)采集；嵌入式控制；DSP+FPGAAbstractMeasurement and control are two indispensable ponents of modern engineering science and technology. Along with the rapid development of puter, network, microelectronics and new technological achievements achieved constantly, more powerful and costeffective approaches can be implemented in measurement and control system. Networkbased virtual measuring instrument and embedded control system is the development tendency of the measurement and control system. This engineering technology achievements not only can be turned into economic benefit quickly but also is of profound meaning in improving military technology and industrial production level.Combining the advantages of networkbased virtual instrument and embedded control technology, a system with network munication function, remote signal acquisition function and control function is designed. The system is designed to meet the synchronization requirement of multicontrolledplant, which has the following performance index—expandability, network munication ability, large data bandwidth, relatively wide application field. With above abilities, networkbased information interaction, embedded control, virtual presentation of operation interface could be brought to realization. Within this system, dataacquisitionamp。網(wǎng)絡(luò)通信模塊是其它兩個(gè)模塊與系統(tǒng)下位各測(cè)控端點(diǎn)聯(lián)系的通道，執(zhí)行以太網(wǎng)通信功能；實(shí)時(shí)監(jiān)控模塊是測(cè)控軟件的核心，對(duì)其它兩模塊有控制、調(diào)用與配置的權(quán)利，為操作者表達(dá)功能需求實(shí)現(xiàn)測(cè)控功能提供操作接口；數(shù)據(jù)后臺(tái)處理模塊根據(jù)監(jiān)控模塊的控制、通過(guò)文件型數(shù)據(jù)庫(kù)對(duì)測(cè)控?cái)?shù)據(jù)進(jìn)行管理。測(cè)控系統(tǒng)軟件由實(shí)時(shí)監(jiān)控、數(shù)據(jù)后臺(tái)處理、網(wǎng)絡(luò)通信三大功能模塊組成。FPGA用以擴(kuò)展與外圍功能模塊的通信接口，如獲取反饋信號(hào)、輸出控制信號(hào)、數(shù)據(jù)鎖存等，這樣就為系統(tǒng)升級(jí)、增加外設(shè)種類提供了廣闊空間，同時(shí)當(dāng)系統(tǒng)有大量復(fù)雜算法需要運(yùn)算時(shí)，可以接受DSP分配的數(shù)據(jù)處理任務(wù)。測(cè)控卡的功能架構(gòu)為DSP+FPGA結(jié)構(gòu)，DSP采用數(shù)據(jù)處理性能優(yōu)異、片上外設(shè)豐富的最新一代的工控專用浮點(diǎn)處理器TMS320F28335，F(xiàn)PGA選用片上邏輯資源量大、性價(jià)比高的EP2C8Q208CN。系統(tǒng)的設(shè)計(jì)目標(biāo)是：滿足多受控系統(tǒng)同步的需要，搭建具有網(wǎng)絡(luò)化、可擴(kuò)展化、大數(shù)據(jù)帶寬特點(diǎn)的，應(yīng)用領(lǐng)域相對(duì)廣泛的測(cè)控平臺(tái)系統(tǒng)，實(shí)現(xiàn)信息的遠(yuǎn)程通信、測(cè)控功能的嵌入式實(shí)現(xiàn)、操作界面的虛擬化呈現(xiàn)。網(wǎng)絡(luò)化的虛擬信號(hào)測(cè)量?jī)x器與嵌入式控制系統(tǒng)是當(dāng)今測(cè)控系統(tǒng)的發(fā)展趨勢(shì)，該工程技術(shù)領(lǐng)域的研究成果不僅能夠很快地實(shí)現(xiàn)經(jīng)濟(jì)效益的轉(zhuǎn)化，而且對(duì)提高一國(guó)的軍工科技水平和工業(yè)生產(chǎn)水平也具有深遠(yuǎn)的意義。 碩士學(xué)位論文網(wǎng)絡(luò)化測(cè)控系統(tǒng)的設(shè)計(jì)與開(kāi)發(fā)DESIGN AND DEVELOPMENT OF NETWORKED MEASUREMENT AND CONTROL SYSTEM 哈爾濱工業(yè)大學(xué)2014年7月國(guó)內(nèi)圖書(shū)分類號(hào)：TP273 學(xué)校代碼：10213 國(guó)際圖書(shū)分類號(hào)： 密級(jí)：公開(kāi)工學(xué)碩士學(xué)位論文網(wǎng)絡(luò)化測(cè)控系統(tǒng)的設(shè)計(jì)與開(kāi)發(fā)碩士研究生:導(dǎo)師:副教授申請(qǐng)學(xué)位:工學(xué)碩士學(xué)科、專業(yè):控制科學(xué)與工程所在單位:航天學(xué)院答辯日期:2014年7月授予學(xué)位單位:哈爾濱工業(yè)大學(xué)Classified Index: TP273: Dissertation for the Master Degree in EngineeringDESIGN AND DEVELOPMENT OF NETWORKED MEASUREMENT AND CONTROL SYSTEM Candidate：JSupervisor：Associate Prof. ZhAcademic Degree Applied for：Master of EngineeringSpeciality：Control Science and EngineeringAffiliation：School of AstronauticsDate of Defence：July, 2014DegreeConferringInstitution：Harbin Institute of Technology摘 要測(cè)量與控制是現(xiàn)代工程科技不可或缺的兩個(gè)重要組成部分。隨著計(jì)算機(jī)、網(wǎng)絡(luò)、微電子等領(lǐng)域的快速發(fā)展及新技術(shù)成果的不斷取得，測(cè)控系統(tǒng)也出現(xiàn)了功能更強(qiáng)大、性價(jià)比更高的實(shí)現(xiàn)方式。本課題結(jié)合網(wǎng)絡(luò)化虛擬儀器和嵌入式控制系統(tǒng)的特點(diǎn)與優(yōu)勢(shì)，設(shè)計(jì)實(shí)現(xiàn)了具有網(wǎng)絡(luò)通信功能和遠(yuǎn)程信號(hào)采集及控制功能的網(wǎng)絡(luò)化測(cè)控系統(tǒng)。系統(tǒng)以數(shù)據(jù)采集控制卡作為測(cè)控現(xiàn)場(chǎng)的具體執(zhí)行端，多測(cè)控卡通過(guò)以太網(wǎng)實(shí)現(xiàn)多端點(diǎn)聯(lián)網(wǎng)，通過(guò)運(yùn)行于上位機(jī)的測(cè)控系統(tǒng)軟件對(duì)整個(gè)系統(tǒng)進(jìn)行整體控制。DSP在測(cè)控端擔(dān)負(fù)主控制器職能，負(fù)責(zé)流程控制、任務(wù)分配及系統(tǒng)各部分軟、硬件的協(xié)調(diào)，主要包括測(cè)控算法的實(shí)現(xiàn)、協(xié)處理器任務(wù)的發(fā)放、以太網(wǎng)通信等。主要的測(cè)量及控制任務(wù)通過(guò)以太網(wǎng)通信由運(yùn)行于上位機(jī)的測(cè)控系統(tǒng)軟件進(jìn)行人工操作。三者既有緊密聯(lián)系的數(shù)據(jù)交互，又有相對(duì)獨(dú)立的功能執(zhí)行。通過(guò)測(cè)控軟件聯(lián)網(wǎng)現(xiàn)場(chǎng)測(cè)控端執(zhí)行系統(tǒng)聯(lián)調(diào)，系統(tǒng)能很好的執(zhí)行由操作者分配的測(cè)控任務(wù)，達(dá)到設(shè)計(jì)目標(biāo)。control cards are the actual executors, which consist the network topology through ethernet and manipulated by someone through the system software running on PC.The functional architecture of the dataacquisitionamp。control endpoints and the other two modules.
