【摘要】：隨著通信技術(shù)的發(fā)展,網(wǎng)絡(luò)的傳輸速率得到了顯著提高,其接入成本也不斷降低,這使得利用網(wǎng)絡(luò)作為萬物互聯(lián)的載體成為了可能。在互聯(lián)網(wǎng)中運用云計算技術(shù)將網(wǎng)絡(luò)資源協(xié)調(diào)利用起來,并按需求為用戶提供內(nèi)容豐富且功能強大的網(wǎng)絡(luò)服務(wù),已成為未來互聯(lián)網(wǎng)發(fā)展的方向。本文通過在嵌入式系統(tǒng)內(nèi)部構(gòu)建服務(wù)器,使嵌入式設(shè)備實現(xiàn)了網(wǎng)絡(luò)通信的功能,若進(jìn)一步將其與公共網(wǎng)絡(luò)相連,便能實現(xiàn)用戶對設(shè)備的遠(yuǎn)程控制與監(jiān)測。另外,嵌入式設(shè)備接入公共網(wǎng)絡(luò),使其成為互聯(lián)網(wǎng)資源的一部分,也為利用云計算技術(shù)將這些資源按需提供給使用者創(chuàng)造了可能。本文采用SOPC技術(shù),利用支持Nios II軟核處理器的FPGA實現(xiàn)了嵌入式服務(wù)器的功能。用戶可以通過客戶端訪問服務(wù)器中的網(wǎng)頁信息,在網(wǎng)頁中對電機驅(qū)動系統(tǒng)進(jìn)行配置、控制與監(jiān)控,實現(xiàn)通過網(wǎng)絡(luò)對嵌入式設(shè)備進(jìn)行操控的過程。本系統(tǒng)設(shè)計時按照SOPC流程進(jìn)行。首先根據(jù)設(shè)計需求,對處理器和外設(shè)接口進(jìn)行定制,構(gòu)建出服務(wù)器硬件模型;然后在硬件基礎(chǔ)上進(jìn)行軟件開發(fā),添加μC/OS-II操作系統(tǒng),并在其上植入NicheStack TCP/IP協(xié)議棧以實現(xiàn)網(wǎng)絡(luò)通信的功能;隨后在操作系統(tǒng)中進(jìn)行用戶應(yīng)用程序的編寫,這些程序主要用來對網(wǎng)絡(luò)數(shù)據(jù)進(jìn)行接收和發(fā)送,并將這些數(shù)據(jù)處理成控制器串口命令,同時用戶應(yīng)用程序也需要實現(xiàn)對設(shè)備反饋信息的處理和封裝,使之可以通過網(wǎng)絡(luò)反饋給客戶端;最后進(jìn)行了電機驅(qū)動平臺的構(gòu)建,完成了系統(tǒng)的設(shè)計功能。另外,為了使用戶可以在網(wǎng)頁上直觀地執(zhí)行配置、控制與監(jiān)測等操作,還需通過網(wǎng)頁編程去實現(xiàn)網(wǎng)頁信息的局部刷新以及網(wǎng)頁圖形的動態(tài)顯示。本文完成了一個面向云服務(wù)的嵌入式平臺的構(gòu)建,成功實現(xiàn)了通過網(wǎng)絡(luò)對設(shè)備的控制與監(jiān)測。用戶可以通過網(wǎng)頁對設(shè)備的各項參數(shù)及功能進(jìn)行配置,同時可在網(wǎng)頁中對設(shè)備的運轉(zhuǎn)情況進(jìn)行直觀的監(jiān)測。平臺進(jìn)行了配置、控制及監(jiān)測功能的測試,均滿足設(shè)計要求。
[Abstract]:With the development of communication technology, the transmission rate of the network has been greatly improved and its access cost has been reduced, which makes it possible to use the network as the carrier of the interconnection of all things. In the Internet, the network resources are used in a coordinated way, and a rich and powerful network is provided for the users according to the demand. Service has become the direction of the development of the Internet in the future. By constructing the server in the embedded system, this paper makes the embedded device realize the function of the network communication. If it is connected with the public network further, the remote control and monitoring of the equipment can be realized. In addition, the embedded equipment is connected to the public network to make it interconnected. A part of network resources also creates the possibility of providing these resources to users on demand by using cloud computing technology. This paper uses SOPC technology to implement the function of embedded server by using FPGA supporting Nios II soft core processor. Users can access the web page information in the server by client and the motor drive system on the web page Configure, control and monitor the process of manipulating the embedded equipment through the network. This system is designed in accordance with the SOPC process. First, according to the design requirements, the processor and peripherals are customized and the hardware model of the server is built. Then the software is developed on the basis of hardware, and the operating system of Mu C/OS-II is added, and The NicheStack TCP/IP protocol stack is implanted to realize the function of network communication; then the user application program is written in the operating system. These programs are mainly used to receive and send the network data, and the data are processed into the serial command of the controller, and the user application needs to implement the device feedback letter. The processing and encapsulation of interest can be fed to the client through the network; finally, the construction of the motor drive platform is built, and the design function of the system is completed. In addition, in order to use the user to perform the configuration, control and monitoring operations on the web page, it also needs to realize the local refresh of the web page information and the web page through the web page programming. This paper completes the dynamic display of the graphics. This paper completes the construction of a cloud oriented embedded platform, successfully realizes the control and monitoring of the equipment through the network. The user can configure the parameters and functions of the equipment through the web page, and can monitor the operation of the equipment in the web page. The platform is configured. The test of control and monitoring functions meet the design requirements.
