【摘要】：在信息技术高速发展的时代,智能、方便、快捷成为人们青睐的主题。随着互联网的迅速发展,智能家居(Smart Home)的概念也慢慢融入了进来。智能家居是互联化的体现,它以小区、住宅为平台,集成了综合布线技术、网络通信技术、安全防范技术、自动控制技术、音视频技术。智能家居系统不仅让管理家居设备更方便,还可以实现家居控制与室内环境监测的一体化。本文在设计系统时考虑到市面上的家电设备大多使用红外遥控技术,因此采用相同的技术实现对家具设备的统一控制。本系统分为红外学习、编码、控制和Zigbee技术两大部分。在红外编码控制方面:为了解决家电种类间编码协议不完全相同,不能统一加装继电器的问题。首先,需要搭建红外发射电路、红外接收电路和红外存储电路,用以保证对家电遥控器红外码的学习,通过学习不同遥控器发出的红外码,最终达到控制不同家电的目的;在家庭环境监测方面:由于人们对生活环境要求越来越高,室内环境监测系统随处可见,本文系统中的另一部分功能是通过CC2530 Zigbee模块采集室内各环境指标,使用户可以清楚地了解室内的实时环境信息。本系统由红外控制模块、网关、Zigbee协调器和Zigbee传感器四部分组成。其中,网关(ARM Cortex-A8)通过路由器连接进行通信,网关通过无线网控制Zigbee协调器,而Zigbee协调器又分别控制红外控制模块的Zigbee节点和Zigbee无线传感器。红外控制模块包含红外学习模块,通过红外码学习,可以使用户能够实现电视、影音设备、电扇和电灯等家电的一体化控制。Zigbee无线传感器可以采集室内的温度、湿度、光照强度、气压强度和空气质量等,并将采集的数据通过CC2530单片机实时发送给网关。由此,用户就能同时实现家居控制和环境监测。
[Abstract]:In the era of high-speed development of information technology, intelligence, convenience, and speediness have become popular themes. With the rapid development of the Internet, the concept of smart home (Smart Home) also slowly integrated into the. Intelligent home is the embodiment of interconnection. It is integrated with comprehensive wiring technology, network communication technology, security prevention technology, automatic control technology, audio and video technology based on residential area and residential platform. Smart home system not only makes the management of home equipment more convenient, but also realizes the integration of home control and indoor environment monitoring. When designing the system, we consider that most of the household appliances in the market use infrared remote control technology, so we adopt the same technology to realize the unified control of furniture and equipment. The system is divided into infrared learning, coding, control and Zigbee technology. In the aspect of infrared coding control: in order to solve the problem that the coding protocol between household appliances is not exactly the same, the relay can not be installed uniformly. Firstly, it is necessary to set up infrared transmitting circuit, infrared receiving circuit and infrared storage circuit to ensure the learning of infrared code of home appliance remote controller, and finally achieve the purpose of controlling different household appliances by learning the infrared code emitted by different remote control. In the aspect of family environment monitoring: because people have higher and higher demands on living environment, indoor environment monitoring system can be seen everywhere. Another part of the function of this system is to collect indoor environmental indicators through CC2530 Zigbee module. Allows users to clearly understand indoor real-time environmental information. The system consists of infrared control module, gateway, Zigbee coordinator and Zigbee sensor. Among them, the gateway (ARM Cortex-A8) communicates through the router connection, the gateway controls the Zigbee coordinator through the wireless network, and the Zigbee coordinator controls the Zigbee node and the Zigbee wireless sensor of the infrared control module respectively. Infrared control module includes infrared learning module, through infrared code learning, can enable users to achieve television, audio and video equipment, electric fans and lights and other household appliances integrated control. Zigbee wireless sensor can collect indoor temperature, humidity, and so on. Light intensity, air pressure intensity and air quality, etc., and the collected data are sent to the gateway through CC2530 MCU in real time. Thus, users can simultaneously achieve home control and environmental monitoring.
