【摘要】：随着科技水平和生活水平的不断提高,人们已经不再满足于传统的家居环境,而逐渐向往自动化、人性化的生活环境。从上世纪80年代智能家居的概念被提出以后,智能家居行业逐步发展,并日益受到重视,具有良好的市场前景。然而,当前的智能家居系统存在智能化与人性化程度低,连接外网的能力差和统一标准缺失等缺陷。针对智能家居系统的研究现状及存在的缺陷,本文提出了一套基于场景模式的智能家居系统设计方案。本系统主要分为家庭节点、家庭网关和监控终端三部分。家庭节点是监控操作实现的直接硬件电路,负责接收并执行网关的控制命令,或上传相应报警信息；家庭网关是整个系统的通信枢纽,负责协调整个系统的运作；监控终端是用户监控的直接界面设备,通过与家庭网关的通信实现对家庭节点的监控。此系统不仅具有简单的设备控制、消防安防报警和参数采集功能,还具有场景模式控制功能,可以通过场景模式的设置,实现对多个设备的联合控制,使得家庭设备的运行状态符合用户对当前环境的需求。首先,对家庭节点的硬件电路和软件流程进行设计。各个节点的硬件电路是在nRF24LE1应用电路的基础上加入相应的执行电路或采集电路实现的；软件设计主要是采用CSMA冲突检测方法,制定了一套简单的无线通信协议,并在此协议基础上实现了家庭内部通信网络。其次,对家庭网关的硬件连接和服务器程序进行设计。网关控制器S3C2440通过无线模块实现与家庭内部网络的通信；通过无线网卡和GPRS模块实现与家庭外部网络的通信。网关服务器程序会实时检测来自外部网络的命令信息和内部网络的数据信息,并对其中的有效信息及时做出相应处理。最后,对Android监控终端软件进行设计。该软件具有服务器登陆功能和监控功能。服务器登陆和监控有短信和网络两种方式,以适应用户不同的监控环境。控制功能通过SQLite数据库命令查询和发送实现；监测功能会实时监测节点的上传信息,并对有效信息进行显示和报警。测试表明,论文设计的系统可以正常稳定地运行。此系统的场景控制功能迎合了人们对家居环境智能化、人性化的需求,为国内智能家居行业的发展提供了新思路。
[Abstract]:With the development of science and technology and living standard, people are no longer satisfied with the traditional living environment, but yearn for the automatic and humanized living environment. Since the concept of smart home was put forward in the 1980s, the smart home industry has gradually developed and been paid more and more attention, which has a good market prospect. However, the current smart home system has some shortcomings, such as low degree of intelligence and humanization, poor ability to connect to external network and lack of unified standard. Aiming at the research status and defects of smart home system, this paper presents a design scheme of intelligent home system based on scene mode. The system is mainly divided into three parts: home node, home gateway and monitoring terminal. The home node is the direct hardware circuit of the monitoring operation, which is responsible for receiving and executing the control command of the gateway, or uploading the corresponding alarm information, and the home gateway is the communication hub of the whole system, which is responsible for coordinating the operation of the whole system. The monitoring terminal is a direct interface device for user monitoring. It can monitor the family nodes through communication with the home gateway. The system not only has the functions of simple equipment control, fire protection and alarm and parameter collection, but also has the function of scene mode control, which can realize the joint control of multiple equipments by setting the scene mode. Make the running state of the home device meet the user's needs for the current environment. Firstly, the hardware circuit and software flow of the home node are designed. The hardware circuit of each node is realized by adding corresponding execution circuit or acquisition circuit on the basis of nRF24LE1 application circuit, and the software design mainly adopts CSMA conflict detection method, and formulates a set of simple wireless communication protocol. On the basis of this protocol, the communication network within the home is realized. Secondly, the hardware connection and server program of home gateway are designed. The gateway controller S3C2440 realizes the communication with the home internal network through the wireless module, and realizes the communication with the home external network through the wireless network card and the GPRS module. The gateway server program detects the command information from the external network and the data information from the internal network in real time and processes the effective information in time. Finally, the software of Android monitoring terminal is designed. The software has server login function and monitoring function. Server login and monitoring have two ways: SMS and network to adapt to different monitoring environments. The control function is realized by SQLite database command query and sending, and the monitoring function can monitor the upload information of nodes in real time, and display and alarm the effective information. The test shows that the system designed in this paper can run normally and stably. The scene control function of this system caters to people's demand for intelligent and humanized home environment, and provides a new way for the development of domestic smart home industry.
