【摘要】：近年来,随着通信技术的迅速发展,信息化程度越来越高,人们对家居的智能化也有了更高的期盼,盼望可以随时随地控制家居,创造更加舒适化、安全化、人性化、智能化的居住环境。现代家居将一些静止的设备转变为具有能动智能的工具,使得家居与外部环境保持信息的交流,实现了信息的全方位交互。随着家居数字化、建筑智能化及其相关技术的发展,智能家居正逐渐改变人们的生活方式和工作方式,智能化家居将逐步走入人们的生活。本文研究设计了基于ARM的智能家居温控系统,系统实现了智能控制空调的功能。智能的系统就是能根据系统所处状态的不同来选择不同的控制方式。比如当人在室内温度超过室内温度设定上限值,系统应该打开空调,当人离开房间一段时间后,系统应该关闭空调。当人在室外控制空调时,系统应该根据远程控制指令控制空调等等。这里我用两个状态位来共同表示系统所处的状态,一个是人状态位,表示人当前是处于室内状态还是室外状态;一个是远程控制状态位,表示当前是否有远程控制。系统就是根据这两个状态位来决定采取控制的方式。主要研究内容包括MCU(Micro Controller Unit,微控制单元)的选型,最小系统的设计,温度采集模块、人体识别模块、GPRS(General Packet Radio Service,通用分组无线业务)模块、红外学习模块的选择以及它们与主MCU的硬件连接。软件设计搭建Web(World Wide Web,全球广域网)服务器,手机通过Web浏览器访问Web服务器实现远程监控;以及在主芯片上移植UC/OS-II嵌入式实时操作系统实现多任务协调安全工作的功能。硬件设计采用模块设计思想,在系统软件的协调下实现整体的功能。在软件设计上,将系统划分成一系列具有优先级顺序的任务,通过UCOS-II嵌入式系统来协调这些任务,进行任务之间的切换。
[Abstract]:In recent years, with the rapid development of communications technology, the degree of information is becoming more and more high, people also have a higher expectation of home intelligence, hope to control the home anytime, anywhere, create more comfortable, safe, humanized, Intelligent living environment Modern home transforms some static devices into dynamic intelligent tools, which make home and external environment keep information exchange and realize the omnidirectional interaction of information. With the development of digital home, intelligent building and its related technology, smart home is gradually changing people's way of life and working style, intelligent home will gradually enter into people's life. In this paper, the intelligent home temperature control system based on ARM is designed. The system realizes the function of intelligent control air conditioning. Intelligent system is to choose different control methods according to the state of the system. For example, when a person exceeds the upper limit of indoor temperature, the system should turn on the air conditioner, and when the person leaves the room for a period of time, the system should turn off the air conditioning. When people control the air conditioning outdoors, the system should control the air conditioning according to the remote control instructions. Here I use two state bits to represent the state of the system, one is the human state bit, which indicates whether the person is currently in an indoor state or an outdoor state, and the other is a remote control state bit, indicating whether there is a remote control at present. The system is based on these two state bits to decide how to take control. The main research contents include the selection of MCU (Micro Controller Unit, micro-control unit, the design of minimum system, the temperature acquisition module, the human body identification module and the GPRS (General Packet Radio Service, general packet radio service) module. The selection of infrared learning modules and their hardware connection with the main MCU. The software is designed to build the Web (World Wide Web, wide area network (WAN) server, the mobile phone accesses the Web server through the Web browser to realize the remote monitoring, and the UC/OS-II embedded real-time operating system is transplanted on the main chip to realize the function of multi-task coordination and security work. The hardware design adopts the module design idea, realizes the whole function under the coordination of the system software. In software design, the system is divided into a series of tasks with priority order, and these tasks are coordinated by UCOS-II embedded system, and the tasks are switched between them.
