【摘要】：隨著無線網(wǎng)絡(luò)技術(shù)的發(fā)展，有關(guān)WiFi無線網(wǎng)絡(luò)通信與控制技術(shù)取得長足進步，在當今世界上的大多數(shù)國家里，WiFi技術(shù)已經(jīng)成為無線網(wǎng)絡(luò)寬帶接入的主流標準。在國內(nèi)相當一部分城市都提供了WiFi信號，如許多電話亭被改造為WiFi信號熱點。在大街上，我們只要隨身攜帶帶有WiFi模塊的電子產(chǎn)品終端，就可接入互聯(lián)網(wǎng)沖浪。眼下，物聯(lián)網(wǎng)也如火如荼地發(fā)展，人們追求手持終端的智能性和良好的操作控制能力及相關(guān)設(shè)備的互聯(lián)互控的實用操作。若將一把能夠控制遠端的智能電子設(shè)備掌握在手，就可以省去很多不必要的麻煩在網(wǎng)絡(luò)的另一端就可以輕松解決問題。當今手持智能終端大多是采用ARM架構(gòu)。因此在ARM上通過研究WiFi無線通信終端實現(xiàn)智能控制顯得很有意義。 本課題主要基于三星公司的S3C2440A為核心處理器，通過搭建其外圍電路來設(shè)計開發(fā)通用的無線控制終端的硬件，在控制終端的硬件平臺即本課題中的目標板上移植Linux嵌入式操作系統(tǒng)，設(shè)計一個穩(wěn)定可靠的無線模塊與目標板相連接，能夠?qū)崿F(xiàn)目標板通過WiFi信號組建局域網(wǎng)或者通過WiFi熱點連接互聯(lián)網(wǎng)，并能控制網(wǎng)中的另一智能設(shè)備，研究智能終端在組網(wǎng)中的相互訪問和控制能力。 本課題在軟件方面，采用嵌入式Linux系統(tǒng)作為操作系統(tǒng)，使用Qtopia桌面環(huán)境。詳細分析了該無線智能控制系統(tǒng)的軟件部分，包括從底層到頂層的實現(xiàn)，，如Linux內(nèi)核的圖形化配置與移植，根文件系統(tǒng)的相關(guān)制作，WiFi無線網(wǎng)卡、LCD、觸摸屏校準的程序設(shè)置、Qtopia桌面環(huán)境的移植、無線控制的時延、信號的反饋等。 經(jīng)系統(tǒng)實驗測試結(jié)果表明，該無線智能控制終端能夠在WiFi信號覆蓋區(qū)域連接互聯(lián)網(wǎng)，也可在兩兩組網(wǎng)即組成局域網(wǎng)，并能與通過聯(lián)網(wǎng)模擬的宿主機進行連接與相互控制。目標板可用觸摸屏進行操作。在聯(lián)網(wǎng)狀況下，利用SSH協(xié)議能夠?qū)崿F(xiàn)遠程智能控制等。
[Abstract]:With the development of wireless network technology, WiFi wireless network communication and control technology has made great progress. In most countries in the world today, WiFi technology has become the mainstream standard for broadband access to wireless networks. In a considerable number of cities in China, WiFi signals have been provided, such as many telephone booths have been transformed into hot spots of WiFi signals. As long as we carry an electronic device terminal with a WiFi module, we can access the Internet of things. Now, the Internet of things is in full swing. People pursue the intelligence of the handheld terminal, the good operation control ability and the practical operation of the interconnection and mutual control of the related equipment. If a intelligent electronic device which can control the remote part is in hand, At the other end of the network, the problem can be solved easily. Nowadays, most of the handheld intelligent terminals are based on ARM architecture. Therefore, it is very meaningful to study the intelligent control of WiFi wireless communication terminals on ARM. This subject is mainly based on S3C2440A of Samsung company as the core processor, by building its peripheral circuit to design and develop the hardware of the general wireless control terminal. Linux embedded operating system is transplanted on the target board of the control terminal, and a stable and reliable wireless module is designed to connect with the target board. The target board can construct local area network through WiFi signal or connect to Internet through WiFi hot spot, and can control another intelligent device in the network, and study the mutual access and control ability of intelligent terminal in the network. In the software aspect, the embedded Linux system is used as the operating system and the Qtopia desktop environment is used. The software part of the wireless intelligent control system is analyzed in detail, including the realization from the bottom to the top. Such as the graphical configuration and transplantation of the Linux kernel, the related production of the root file system, the LCDs of the WiFi wireless network card, the programming of the touch screen calibration, the transplant of the Qtopia desktop environment, the delay of wireless control, the feedback of the signal, etc. The experimental results show that the wireless intelligent control terminal can connect to the Internet in the WiFi signal coverage area, and can also form a local area network in two sets of networks. The target board can be operated by touch screen. Under the condition of networking, remote intelligent control can be realized by using SSH protocol.
