【摘要】：近幾年,智能家居的概念在國內(nèi)已廣為人知,智能家居技術(shù)在國內(nèi)外也得到了迅速的發(fā)展。智能家居不僅可以為人們提供傳統(tǒng)的居住生活環(huán)境,而且還加入了物聯(lián)網(wǎng)和互聯(lián)網(wǎng)的相關(guān)技術(shù),使人們可以擁有網(wǎng)絡(luò)家電、信息家電、智能安防等全方位功能的居住環(huán)境。如今,越來越多的人們向往智能化、信息化和網(wǎng)絡(luò)化的生活方式,因此,智能家居將會有越來越多的市場需求。本文通過分析智能家居系統(tǒng)的功能和需求,設(shè)計了一款功能完善、成本較低、安全、穩(wěn)定的智能家居系統(tǒng)。本文采用Cortex-A9作為微處理器核心,對智能家居無線通信和環(huán)境監(jiān)測、紅外學(xué)習(xí)與發(fā)射進(jìn)行設(shè)計與實現(xiàn)。系統(tǒng)設(shè)計整體分為三大部分:Zigbee終端節(jié)點數(shù)據(jù)的采集與控制、主控制器的程序設(shè)計、IP攝像頭程序設(shè)計。為了減少信號的串?dāng)_,本文選用Zigbee無線通信協(xié)議,選用TI公司最新的CC2530芯片來解決信號的串?dāng)_問題。主控制器通過串口控制協(xié)調(diào)器,實現(xiàn)對節(jié)點設(shè)備的管理,包括允許入網(wǎng)、不允許入網(wǎng),恢復(fù)出廠設(shè)置。傳感設(shè)備節(jié)點通過Zigbee網(wǎng)絡(luò)將采集到的數(shù)據(jù)周期發(fā)送給主控制器,主控制器不但可以將檢測到的環(huán)境信息實時更新在環(huán)境界面中,還能夠通過控制界面隨時控制節(jié)點。主控制器發(fā)送命令通知紅外轉(zhuǎn)發(fā)器學(xué)習(xí)紅外信號,然后存儲到主控制器的數(shù)據(jù)庫中,以備下次發(fā)送紅外信號使用。通過無線網(wǎng)絡(luò),主控制器可以訪問IP攝像頭,用戶可以設(shè)置IP攝像頭的視頻質(zhì)量、開啟語音、關(guān)閉語音等監(jiān)控家庭情況。本文設(shè)計了一個功能較全面的智能家居系統(tǒng),經(jīng)測試,通過IOTC協(xié)議主控制器能夠成功訪問到IP攝像頭,主控制器可以通過Zigbee無線通信協(xié)議控制節(jié)點并且能夠成功接收節(jié)點的反饋信息,驗證結(jié)果表明本文所設(shè)計的智能家居系統(tǒng)符合使用要求。
[Abstract]:In recent years, the concept of smart home has been widely known in China, smart home technology has also been rapid development at home and abroad. Smart home can not only provide people with traditional living environment, but also join the Internet of things and Internet technology, so that people can have network appliances, information appliances, intelligent security and other comprehensive functions of living environment. Nowadays, more and more people yearn for intelligent, information and network lifestyle. Therefore, smart home will have more and more market demand. By analyzing the functions and requirements of smart home system, this paper designs a smart home system with perfect function, low cost, safety and stability. In this paper, Cortex-A9 is used as the core of microprocessor to design and implement wireless communication, environment monitoring, infrared learning and transmitting in smart home. The system design is divided into three parts: data acquisition and control of Zigbee terminal node, program design of main controller and program design of IP camera. In order to reduce signal crosstalk, this paper chooses Zigbee wireless communication protocol and TI's newest CC2530 chip to solve the signal crosstalk problem. The main controller realizes the management of the node equipment through the serial port control coordinator, including allowing access to the network, not allowing access to the network, and resuming the factory setting. The sensor node sends the collected data cycle to the main controller through the Zigbee network. The main controller not only can update the detected environmental information in the environment interface, but also can control the node at any time through the control interface. The main controller sends a command to the infrared repeater to learn the infrared signal, and then stores it in the database of the main controller for the next time sending the infrared signal. Through the wireless network, the main controller can access the IP camera, users can set the video quality of the IP camera, turn on the voice, turn off the voice and monitor the situation of the home. A fully functional smart home system is designed in this paper. After testing, the main controller of IOTC protocol can access the IP camera successfully. The main controller can control the nodes through Zigbee wireless communication protocol and can receive the feedback information from the nodes successfully. The verification results show that the smart home system designed in this paper meets the requirements.
