【摘要】：隨著智能穿戴設(shè)備、物聯(lián)網(wǎng)、移動(dòng)互聯(lián)網(wǎng)大潮的到來(lái),低功耗藍(lán)牙技術(shù)(Bluetooth Low Energy,BLE)已然成為了移動(dòng)互聯(lián)網(wǎng)智能連接的重要技術(shù)支撐,但是由于其短距離通信的特性,限制了在各種領(lǐng)域的應(yīng)用發(fā)展,所以為了改善這種現(xiàn)狀,基于Android平臺(tái)設(shè)計(jì)藍(lán)牙通信系統(tǒng)以及能夠?qū)崿F(xiàn)更遠(yuǎn)距離數(shù)據(jù)傳輸?shù)南敕ū銘?yīng)運(yùn)而生,進(jìn)而刺激了當(dāng)前課題研究的展開。本文基于BLE、Android技術(shù)的研究現(xiàn)狀及200m傳輸距離的指標(biāo)需求,將BLE技術(shù)、安卓系統(tǒng)以及高增益天線技術(shù)相結(jié)合,設(shè)計(jì)了基于Android手機(jī)的遠(yuǎn)距離藍(lán)牙通信系統(tǒng),該系統(tǒng)由主機(jī)端Android手機(jī)、從機(jī)端BLE模塊及高增益微帶陣列天線三部分構(gòu)成。首先,在IAR編譯環(huán)境中基于藍(lán)牙4.0協(xié)議棧使用C語(yǔ)言完成了硬件模塊初始化、操作系統(tǒng)抽象層任務(wù)事件驅(qū)動(dòng)機(jī)制設(shè)計(jì)、模塊廣播、與主機(jī)端數(shù)據(jù)交互協(xié)議機(jī)制的功能。然后,設(shè)計(jì)完成了應(yīng)用于BLE通信模塊高增益接收天線,從單元貼片和基板的尺寸計(jì)算、微帶陣列天線饋電方式、阻抗匹配變換器及組陣饋電網(wǎng)絡(luò)的設(shè)計(jì)出發(fā),完成了微帶貼片單元、二元天線陣、2×2天線陣的仿真優(yōu)化與結(jié)果分析,并對(duì)2×2陣列天線進(jìn)行了加工與實(shí)物測(cè)試。最后,基于Android手機(jī)平臺(tái),在Android Studio編譯環(huán)境中,使用Java編程語(yǔ)言搭建了應(yīng)用軟件的搜所和通信界面,并完成了外圍設(shè)備掃描連接、名稱地址信息顯示、傳輸速率記錄、通信字節(jié)數(shù)的統(tǒng)計(jì)等移動(dòng)終端功能。本課題從系統(tǒng)功耗、傳輸速率、通信距離、平均漏包數(shù)方面進(jìn)行了測(cè)試與系統(tǒng)可靠性分析,達(dá)到了預(yù)期指標(biāo),驗(yàn)證了基于Android手機(jī)藍(lán)牙技術(shù)的遠(yuǎn)距離BLE通信系統(tǒng)的可行性,由于本設(shè)計(jì)具有低成本、低功耗、移動(dòng)應(yīng)用軟件靈活性強(qiáng)、天線增益可拓展、擺脫短距離的束縛及實(shí)現(xiàn)遠(yuǎn)距離數(shù)據(jù)傳輸?shù)葍?yōu)點(diǎn),必將成為移動(dòng)BLE通信的應(yīng)用趨勢(shì),進(jìn)而為實(shí)現(xiàn)更遠(yuǎn)距離BLE通信系統(tǒng)的可能性及其應(yīng)用奠定了基礎(chǔ)。
[Abstract]:With smart wearable devices, networking, mobile Internet tide coming, low-power Bluetooth Technology (Bluetooth Low Energy, BLE) has become an important technical support for intelligent mobile Internet connection, but because of the short distance communication characteristics, limits the application and development in the field of all kinds, so in order to improve the situation, design of Bluetooth Android communication system platform and can achieve longer distance data transmission came into being based on the idea, which stimulates the current research. The index demand status and 200m transmission distance of BLE, based on Android technology, BLE technology, Android systems and high gain antenna technology, designed the remote Bluetooth communication system based on the Android mobile phone, the system consists of host Android mobile phone, from the terminal BLE module and high gain microstrip antenna array is composed of three parts. First, in the IAR compiler environment, based on Bluetooth 4 protocol stack, C language is used to complete the function of initialization of hardware module, operation system abstraction layer, task event driven mechanism design, module broadcasting, and data interaction protocol with host. Then, completed the design of BLE communication module used in high gain antenna, calculated from the patch and the substrate size impedance of microstrip array antenna, feed mode, the converter design and array feed network, completed the simulation and optimization results of microstrip patch antenna array unit, two yuan, 2 x 2 antenna array the analysis, and the 2 x 2 antenna array processing and physical test. Finally, based on the Android mobile phone platform, in the Android Studio compiler environment, the use of Java programming language to build the application software search and communication interface, and the peripheral equipment, scanning connection name and address information display, transmission rate, record the number of bytes of communication statistics function of the mobile terminal. This topic from the system power consumption, transmission rate, communication distance and average leakage packets on the reliability test and analysis system, to achieve the desired target, verify the feasibility of remote BLE communication system based on Bluetooth technology for Android mobile phone, because has the advantages of low cost, low power consumption, the mobile application software flexibility, antenna gain development, get rid of the shackles of short distance and long-distance data transmission, the design will become the trend of application of BLE in mobile communication, and then set the foundation for the realization of the possibility and application foundation farther distance BLE communication system.
