【摘要】：工業(yè)無線傳感器網(wǎng)絡(luò)協(xié)調(diào)器是整個(gè)網(wǎng)絡(luò)的主控制器,負(fù)責(zé)網(wǎng)絡(luò)的建立、成員身份管理、鏈路狀態(tài)信息管理以及分組轉(zhuǎn)發(fā)等任務(wù)。目前國(guó)內(nèi)存在的工業(yè)無線傳感器網(wǎng)絡(luò)應(yīng)用中,往往是借助于國(guó)外成熟的單芯片解決方案和不透明的協(xié)議棧。而協(xié)調(diào)器需要具備強(qiáng)大的計(jì)算能力和存儲(chǔ)能力,隨著網(wǎng)絡(luò)規(guī)模的增大,單芯片解決方案已不能滿足協(xié)調(diào)器的功能和性能需求。并且不透明的協(xié)議棧在安全性、可定制性、可靠性、可移植性和效率等方面都值得去衡量。 在分析目前國(guó)內(nèi)外工業(yè)無線傳感器網(wǎng)絡(luò)協(xié)調(diào)器應(yīng)用的基礎(chǔ)上,提出了一種基于S3C2440A微處理器的解決方案,并且詳細(xì)探討了協(xié)調(diào)器系統(tǒng)硬件和軟件的設(shè)計(jì)和實(shí)現(xiàn)方案。系統(tǒng)硬件設(shè)計(jì)的外圍接口電路主要包括電源接口、射頻接口、LCD接口、以太網(wǎng)接口、串行接口等。系統(tǒng)軟件設(shè)計(jì)主要包括嵌入式Linux操作系統(tǒng)的構(gòu)建、射頻模塊驅(qū)動(dòng)程序的設(shè)計(jì)實(shí)現(xiàn)、FreakZ開源協(xié)議棧的移植、協(xié)調(diào)器系統(tǒng)和上位機(jī)圖形用戶程序的設(shè)計(jì)實(shí)現(xiàn)以及對(duì)測(cè)試節(jié)點(diǎn)上TinyOS的移植。論文還對(duì)數(shù)據(jù)的可靠性和安全性進(jìn)行了分析,然后給出了系統(tǒng)的調(diào)試和測(cè)試過程,最后給出了對(duì)整個(gè)系統(tǒng)研究過程的總結(jié)并給出了系統(tǒng)可以改進(jìn)之處。 本研究的嵌入式Linux工業(yè)無線傳感器網(wǎng)絡(luò)協(xié)調(diào)器在硬件上具有強(qiáng)大的處理計(jì)算能力、較大的存儲(chǔ)容量、批量數(shù)據(jù)網(wǎng)絡(luò)傳輸、彩色液晶顯示和觸摸輸入等功能。軟件上運(yùn)行穩(wěn)定可靠的嵌入式Linux操作系統(tǒng)、穩(wěn)定的射頻模塊驅(qū)動(dòng)程序、開源可定制的FreakZ協(xié)議棧以及友好的上位機(jī)和協(xié)調(diào)器圖形用戶界面應(yīng)用程序。本協(xié)調(diào)器系統(tǒng)運(yùn)行穩(wěn)定可靠,可應(yīng)用于工業(yè)現(xiàn)場(chǎng)的信號(hào)監(jiān)測(cè)和控制,具有良好的市場(chǎng)價(jià)值和發(fā)展前景。 論文總共分為六個(gè)章節(jié),第一章主要闡述了課題的背景、意義以及研究現(xiàn)狀,并且對(duì)論文的總體結(jié)構(gòu)進(jìn)行了介紹；第二章主要闡述了工業(yè)無線傳感器網(wǎng)絡(luò)協(xié)調(diào)器總體方案設(shè)計(jì),主要包含硬件平臺(tái)設(shè)計(jì)和軟件平臺(tái)設(shè)計(jì)兩個(gè)方面；第三章和第四章分別對(duì)第二章闡述的硬件和軟件方面的設(shè)計(jì)和實(shí)現(xiàn)進(jìn)行了詳細(xì)的論述；第五章是協(xié)調(diào)器系統(tǒng)的調(diào)試測(cè)試部分；第六章對(duì)整個(gè)研究進(jìn)行了總結(jié)和展望。
[Abstract]:The industrial wireless sensor network coordinator is the main controller of the whole network, which is responsible for the establishment of the network, membership management, link state information management and packet forwarding.At present, industrial wireless sensor network applications in our country often rely on mature single chip solutions and opaque protocol stacks.The coordinator needs powerful computing power and storage capacity. With the increase of network size, the single-chip solution can not meet the functional and performance requirements of the coordinator.And the opaque protocol stack is worth measuring in terms of security, customization, reliability, portability and efficiency.On the basis of analyzing the application of industrial wireless sensor network coordinator at home and abroad, a solution based on S3C2440A microprocessor is proposed, and the design and implementation of hardware and software of the coordinator system are discussed in detail.The peripheral interface circuit mainly includes power interface, RF interface and LCD interface, Ethernet interface, serial interface and so on.The system software design mainly includes the construction of embedded Linux operating system and the design of RF module driver to realize the transplantation of FreakZ open source protocol stack.The design and implementation of the coordinator system and the upper computer graphics user program, as well as the porting of TinyOS on the test node.The paper also analyzes the reliability and security of the data, then gives the debugging and testing process of the system, and finally gives a summary of the whole system research process and points out the system can be improved.The embedded Linux industrial wireless sensor network coordinator in this paper has powerful processing and computing power, large storage capacity, bulk data network transmission, color LCD display and touch input functions in hardware.The software runs stable and reliable embedded Linux operating system, stable RF module driver, open source customizable FreakZ protocol stack and friendly upper computer and coordinator graphical user interface application program.The system is stable and reliable, and can be used in signal monitoring and control of industrial field. It has good market value and development prospect.The thesis is divided into six chapters. The first chapter mainly describes the background, significance and research status of the subject, and introduces the overall structure of the paper. Chapter 2 mainly describes the overall scheme design of industrial wireless sensor network coordinator.It mainly includes two aspects: hardware platform design and software platform design. Chapter 3 and 4 discuss the design and implementation of hardware and software in chapter 2 respectively. Chapter 5 is the debugging and testing part of the coordinator system.Chapter six summarizes and prospects the whole research.
