摘要：随着物联网概念的普及，家居智能化成为当下研究的热点方向。在家居环境中，安防问题显得尤其重要，家居智能安防系统能够帮助居民合理及有效的保证整个家居环境的安全。但是家居智能安防系统在国内的普及率一直不高，究其原因，主要在于不同人群对于安防系统的要求有所差异以及控制系统价格相对较高。因此，一种普适性、性价比高且操作简单的家居智能安防系统需要提供给社会大众。

本文设计开发并完成了一套基于Arduino的家居智能安防系统，从基本的功能需求着手，借助一系列传感器设备及模块的帮助，实现家居安防系统的智能化。因为Arduino开源的特性，后续可以根据不同用户对于功能要求的差异而更改。通过对目前各种家居智能安防系统功能进行统计分析，选择共性功能进行设计，并提出一套总体方案。该方案包括监控并发现整个家居环境内的严重异常，如火灾、门窗破损、燃气泄漏等险情，且险情发生时能够记录房屋重点区域的图像，另外监测数据及警报信息能够自动上传至云端以及移动端以供远程查看以及获知险情，及时处理险情。

硬件方面包括温度传感器、人体红外传感器、火焰传感器、烟雾传感器、有源蜂鸣器、串口摄像头、WIFI模块以及ArduinoUNOR3主控制器。经过测试，本设计能够实现将采集的温度、人体红外、火焰、烟雾、警报等信息上传至云服务器，同时能够通过移动终端APP查看，而布置在现场的串口摄像头能够拍摄险情图像保存在本地，因此家居智能安防系统满足预期要求。

Abstract：As the concept of internet of things become popularized, home intelligent become a hot direction of the current study. In the home environment, the security problem is particularly important, home intelligent security system to help residents reasonable and effective to ensure the safety of the entire home environment. But the penetration rate of the home intelligent security system in our country is not high, the reason is mainly due to different groups of security systems for the different requirements and control system prices are relatively high. Therefore, a universal, cost-effective and simply operating of the home intelligent security system needs to be provided in the community.

This article has designed and developed a set of home intelligent security system based on Arduino, from the basic functional requirements, with a series of sensor equipment and modules to help achieve the intelligent home security system. Because of the characteristic of Arduino's open source, subsequent changes can be made depending on the differences in user requirements for different users. Through the statistical analysis of the function of various intelligent home security systems, the design of common function is selected and a set of general scheme is put forward. The program includes monitoring and finding serious anomalies throughout the home environment, such as fires, doors and windows damaged, gas leaks, when the danger occurs, the image of the key area of the house can be recorded, and the monitoring data and alarm information  can be automatically uploaded to the cloud and moved for remote viewing and informing of the danger, to solve the dangerous situation timely.

Hardware includes temperature sensor, human body infrared sensor, flame sensor, smoke sensor, active buzzer, serial camera, WIFI module and Arduino UNO R3 main controller. After testing, the design can achieve the collection of temperature, human infrared, flame, smoke, alarm and other information uploaded to the cloud server, and can be viewed through the mobile terminal APP, and arranged in the field of the serial camera can take pictures of dangerous situation stored in the local, so the home intelligent security system meets the expected requirements.
