【摘要】：白光LED由于綠色環(huán)保節(jié)能,將逐漸成為日常照明光源。由于白光LED具有高調(diào)制速率,以白光LED作為光源的可見光通信技術(shù)逐漸引起重視。白光LED不僅可以作為照明光源還可以作為通信信號源的特征,使白光LED可見光通信技術(shù)具有非常廣闊的應(yīng)用前景。白光光通信技術(shù)因保密性高、無電磁輻射非常適合在飛機(jī)、醫(yī)院、礦井等通信條件特殊的環(huán)境中應(yīng)用。本文以醫(yī)院掛號為應(yīng)用背景,研究了基于Android移動(dòng)設(shè)備的可見光通信系統(tǒng)。該系統(tǒng)主要由CPLD控制的服務(wù)端和Android設(shè)備開發(fā)的客戶端構(gòu)成。為解決上下行鏈路信號在通信過程中產(chǎn)生的干擾,確定了空間分割信道模型。通過對Android設(shè)備的性能分析,使用LED點(diǎn)陣作為信源增大每幀信息的容量。在CPLD中設(shè)計(jì)了LED顯示屏控制電路和信息處理電路,同時(shí)在手機(jī)上實(shí)現(xiàn)圖像處理、信息解碼和閃光燈的控制。完成了室內(nèi)白光LED與Android設(shè)備的雙向通信,實(shí)現(xiàn)了醫(yī)院環(huán)境內(nèi)的自助掛號功能。
[Abstract]:White LED will gradually become a daily lighting source because of its green environment and energy saving. Due to the high modulation rate of white light LED, The visible light communication technology with white LED as the light source has attracted more and more attention. White light LED can be used not only as the lighting source but also as the characteristic of the communication signal source. White light LED visible light communication technology has a very broad application prospects. White light communication technology because of high confidentiality, no electromagnetic radiation is very suitable for aircraft, hospitals, Mine and other special communication conditions in the application of the environment. This paper based on the hospital registration as the application background, The visible light communication system based on Android mobile device is studied. The system is mainly composed of the server controlled by CPLD and the client developed by Android device. In order to solve the interference of uplink and downlink signal in the communication process, By analyzing the performance of Android devices, the LED lattice is used as a source to increase the capacity of each frame of information. The control circuit and information processing circuit of LED display screen are designed in CPLD. At the same time, image processing, information decoding and flash control are realized on the mobile phone. The two-way communication between indoor white light LED and Android equipment is completed, and the self-registration function in hospital environment is realized.
