【摘要】：隨著電子信息產(chǎn)業(yè)和互聯(lián)網(wǎng)技術(shù)日新月異的發(fā)展,各種智能化的家居產(chǎn)品被生產(chǎn)出來,對于市場上的一些家居安防產(chǎn)品,大都是面向別墅、企業(yè)等大型地方開發(fā)設(shè)計的,很難實現(xiàn)系統(tǒng)的真正普及應(yīng)用。所以,本課題面向家庭環(huán)境,設(shè)計實現(xiàn)了基于光學(xué)逆向門禁的智能家居安防系統(tǒng)。本課題首先從光學(xué)逆向調(diào)制識別技術(shù)門禁系統(tǒng)開始入手,然后組建了以WiFi通信的家庭無線局域網(wǎng),實現(xiàn)了基于ARM Cortext-A8為核心板的中心控制器和基于MSP430單片機為MCU的節(jié)點終端數(shù)據(jù)采集交互,討論了家居安防具體實現(xiàn),搭建了多功能且成本較低的智能門禁系統(tǒng)。完成了智能門禁系統(tǒng)的中心控制器的設(shè)計,該處理器具有基本的門禁功能,還具有智能安防監(jiān)控中心的作用。門禁系統(tǒng)采用了的光學(xué)逆向調(diào)制技術(shù),完成了門禁系統(tǒng)的鑰匙和鎖體的結(jié)構(gòu)設(shè)計,測試給出了接收最強信號時的壓電片頻率和接收距離;完成了信號加載部分的驅(qū)動壓電片的振蕩電路和檢測部分的放大濾波電路、檢波等電路設(shè)計,編寫了相應(yīng)功能及實現(xiàn)的配套程序和測試程序,并對門禁系統(tǒng)樣機穩(wěn)定性做了必要的測試分析;還完成了中心控制器SDIO接口、LCD顯示屏驅(qū)動等其它硬件電路設(shè)計,為核心板的Linux操作系統(tǒng)的移植提供了基礎(chǔ),并且完成了相應(yīng)的交叉編譯環(huán)境的構(gòu)建。另外,通過GSM模塊實現(xiàn)了用戶和家庭中心處理器遠(yuǎn)程交互。最后,在PC機上利用QT軟件開發(fā)平臺完成了傳感器上傳物理量數(shù)據(jù)界面設(shè)計,并移植嵌入到中心控制器的LCD顯示屏上顯示。節(jié)點終端負(fù)責(zé)采集家庭環(huán)境各種數(shù)據(jù),包括溫度、壓力和煙霧等,將采集到的物理量數(shù)據(jù)直接經(jīng)由WiFi模塊傳送給中心控制器,另外,節(jié)點上設(shè)計了控制電路,可以響應(yīng)中心控制器的指令對家用電器等進行控制。最后,搭建了流媒體系統(tǒng),配置了FFserver服務(wù)器,完成了USB攝像頭的視頻采集,將采集的視頻經(jīng)FFmpeg轉(zhuǎn)換成視頻流實時上傳至服務(wù)器。
[Abstract]:With the rapid development of the electronic information industry and Internet technology, various kinds of intelligent household products have been produced. For some household security products in the market, most of them are developed and designed for villas, enterprises and other large places. It is difficult to realize the real universal application of the system. Therefore, this paper designs and implements a smart home security system based on optical reverse access control. This subject starts with the optical reverse modulation recognition technology, and then sets up the home wireless local area network (WLAN) based on WiFi communication. The central controller based on ARM Cortext-A8 as the core board and the node terminal data collection interaction based on MSP430 single chip computer as MCU are realized. The realization of home security is discussed, and an intelligent access control system with multi-function and low cost is built. The central controller of the intelligent access control system is designed. The processor has the basic function of access control and the function of intelligent security monitoring center. The optical reverse modulation technology used in the access control system has completed the structural design of the key and lock of the access control system. The frequency and the receiving distance of the piezoelectric chip when receiving the strongest signal have been measured and given. The oscillating circuit of driving piezoelectric plate and the circuit of amplifying and filtering and detecting circuit of the signal loading part are completed, and the corresponding function and the corresponding program and test program are written. The stability of the door guard system prototype is tested and analyzed. Other hardware circuits, such as SDIO interface of central controller and driver of LCD display screen, are also designed, which provides the basis for the transplantation of the core board Linux operating system, and completes the construction of the corresponding cross-compiling environment. In addition, the remote interaction between user and home center processor is realized by GSM module. Finally, the interface design of the sensor upload physical quantity data is completed by using the QT software development platform on the PC computer, and the interface is transplanted to the LCD display screen embedded in the central controller. The node terminal is responsible for collecting all kinds of data in the home environment, including temperature, pressure and smoke, and transmits the collected physical quantity data directly through the WiFi module to the central controller. In addition, the control circuit is designed on the node. Can respond to the instructions of the central controller to control household appliances and so on. Finally, the streaming media system is built, the FFserver server is configured, the video capture of the USB camera is completed, and the collected video is converted into the video stream by FFmpeg and uploaded to the server in real time.
