摘要

物联网正在以超越“爆炸”的速度发展,其对世界的影响也是越来越明显。智能家居是现代家居生活的一种趋势,以至于在第三届中国国际物联网(传感器网络)博览会上,家居智能作为“十二五”规划中工信部主推应用领域之一,家居系统产品或网络家居得以展示,物联网技术在智能家居方面的应用已经初见成效。

随着物联网技术在智能家居系统中的应用不断成熟,考虑到智能家居系统中存在的一些安全问题,例如“如何对住宅环境进行实时监测”,以及现有家居安全系统存在的局限性,一种基于物联网的高度网络化智能家居安防系统被设计出来。该智能家居安防系统是针对对非授权访问进行检测、拦截和报警进行设计。本设计涉及到两个节点(CC2530芯片为主控芯片的开发板),一个用作协调器节点,一个用作终端设备;协调器负责组建网络,并维护网络,与PC电脑相连,终端设备负责控制各个功能模块的正常工作,并把数据传递给协调器节点。另外功能模块主要有温湿度采集模块、烟雾检测模块、继电器模块和人体红外传感模块。

本文主要从理论和原理方面对家居物联网的安全系统进行研究,另外也从硬件方面做了很简易的家居环境安全监测系统。

ABSTRACT

Internet of Things is developing with the speed beyond “explode”,and its influence to the world is more and more obvious.Smart home is a trend of modern home life.So in the Third China International Internet of Things(sensor network) Exposition,the Ministry of Industry and Information has taken it as one of the main application fields,household system products and network home are able to be exhibited.

As the Internet of Things technology’s application in smart home matures;considering some security problems exist in the intelligent home system, for example “How to monitor the residential environmentreal-time” and the limitation of the existing household system.A highly networked intelligent household security system based on Internet of Things has been designed. This design involves two nodes(the main chip of development board designed as CC2530 chip),one is coordinator,and another is end-device.The coordinator is responsible for creating the network and maintaining the network.The End-device is responsible for keeping the various functional modules work well,and passing the data to the coordinator node.The main function modules of the hardware design involves temperature and humidity module,smoke detection module,relay module and human infrared sensor module.

This article studies the security system of home networking from the theory and principle aspects,and the hardware design of a simple home’s environment safety monitoring system has been designed.
