智能家居语音控制系统

Intelligent home voice control system

摘要

近年来，随着信息技术的发展，智能产品得到了快速发展，并深入到人们生活的方方面面，人们对智能产品的依赖程度越来越高；同时，人们的居家模式也正在由传统模式向智能家居模式转变。智能家居主要是以自家房屋为平台，可在该系统平台上进行自动化设计、互联网统一管理；亦可对家电进行控制，智能家居方案设计非常标准，同时拓展性强、安全性高。但现如今的智能家居系统造价昂贵，难以全面推广。

因此，本文针对智能家居系统的功能需求和不足，设计满足大众需求的低成本、高可靠性智能家居系统。本系统采用价格成本低廉同时性能非常强大的树莓派3B+作为智能家居语音控制系统的控制中心，Arduino作为下位机，通过麦克风输入自然语言来控制家居中家电的开关控制和实现智能家居的安防需求。树莓派通过识别语言可以进行人机的交互，GPIO口连接人体红外感应的传感器，定时采集人体红外模块数据进行反馈和警报拍照。Arduino作为下位机连接温度湿度模块以及MQ-2烟雾感应模块实时采集各方面数据，数据显示于OLED屏幕上，达到一定的数值后自动报警。该系统造价低廉，功能完善，人机交互功能良好，实现了家电开关的语音控制，同时提供了监测、安防等智能家居的必要

功能。测试结果表明，本系统能够准确实现上述功能，并且性能良好，具有一定的市场应用价值。

Abstract

In recent years, with the development of information technology, smart products have developed rapidly and penetrated into all aspects of people's lives. People have become more and more dependent on smart products; at the same time, people's home model is also changing from traditional model to smart The transformation of the home model. Smart homes are mainly based on their homes as a platform, which can be used for automatic design and unified network management on this system platform; they can also control home appliances. The smart home design is very standard, and has strong expandability and high security. However, today's smart home systems are expensive to manufacture and difficult to fully promote.

So that，this article designs low-cost, high-reliability smart home systems that meet the needs of the public in response to the functional needs and deficiencies of smart home systems. This system uses the Raspberry Pi 3B + with low cost and high performance as the control center of the smart home voice control system, and the Arduino as the lower computer, through the microphone input na柴油抗磨剂

tural language to control the switch control of home appliances in the home and realize the security needs of smart home . The Raspberry Pi can realize human-computer interaction by recognizing the language. The GPIO port is connected to the infrared sensor of the human body, and regularly collects human infrared module data for feedback and alarm photography. Arduino as the lower computer is connected to the temperature and humidity module and the MQ-2 smoke sensor module to collect all aspects of data in real time, and the data is displayed on the OLED screen. When a certain value is reached, it will automatically alarm. The system has low cost, perfect functions, and good human-computer interaction functions. It realizes the voice control of home appliance switches, and provides the necessary functions of smart homes such as monitoring and security. The test results show that the system can accurately realize the above functions, and the performance is good, which has certain market application value.
