【摘要】：随着全球经济的迅猛增长,人们对生活质量的要求也在不断地提高,居住环境更是越来越受到人们的重视。同时,电子、计算机等领域也发展到了一个不可思议的阶段,这为居住环境的智能化提供了坚实的技术支持。在这样的条件下,智能家居诞生并得到了很有利的发展。因此,智能家居也成了近些年来的备受人们关注的话题之一。目前智能家居以及智能家居环境正处于初步发展阶段,各大电子、电器公司都在加大研究力度,以达到早一步占领市场。而伴随着室外的空气质量日益变差,人们也逐渐地关注室内的空气条件。因而如何使得室内的居住环境质量更优质、健康、安全,就是智能家居中一个非常重要的课题。本论文的设计是为了解决室内温度、湿度、烟雾浓度的监视与控制等问题而提出的,同时,为小型智能家庭环境DIY提供借鉴,也为物联网底层监测系统提供参考。本论文主要工作是设计一套家庭环境监控系统,使某台计算机能通过无线传输方式与家庭环境监测系统进行数据交互,以监控室内的温度、湿度、烟雾浓度等参数。该系统主要实现了四大功能：不同的监测器对家庭环境各种参数的采集,将采集到的环境参数通过RS-485电路传送到主控器；主控器通过433MHz无线传输系统将环境参数传输到PC上位机；上位机对家庭环境参数的实时显示以及实现人机交互；通过PC机返回的指令控制加热器、加湿器、报警器来调控室内环境参数。经过测试和实际应用,该系统运行良好,基本实现了各项功能要求,符合设计标准。本设计将温度、湿度、烟雾浓度等空气质量参数融合在一个系统里面,打破了以前的多种参数独立采集方式,为后面的研究提供了很好的借鉴作用。
[Abstract]:With the rapid growth of the global economy, people's requirements for the quality of life are also constantly improving, living environment is more and more attention. At the same time, electronics. Computer and other fields have also developed to an incredible stage, which provides a solid technical support for the intelligent living environment. Under such conditions, smart home was born and got a very favorable development. Smart home has also become one of the most concerned topics in recent years. At present, smart home and smart home environment are in the initial stage of development, the major electronic and electrical companies are increasing research. With the increasing deterioration of outdoor air quality, people gradually pay attention to indoor air conditions. Therefore, how to make indoor living environment quality better, healthy and safe. This paper is designed to solve the indoor temperature, humidity, smoke concentration monitoring and control and other issues, at the same time. For the small intelligent home environment DIY to provide reference, but also for the Internet of things bottom monitoring system to provide reference. The main work of this paper is to design a home environment monitoring system. A computer can exchange data with the home environment monitoring system through wireless transmission to monitor indoor temperature and humidity. The main functions of the system are as follows: different monitors collect various parameters of the home environment, and the collected environmental parameters are transmitted to the main controller through the RS-485 circuit; The main controller transmits the environment parameters to PC through 433MHz wireless transmission system. The real time display of home environment parameters and man-machine interaction are realized by the upper computer. The heater, humidifier and alarm are used to control the indoor environmental parameters through the instruction returned by PC. After testing and practical application, the system runs well and basically realizes the functional requirements. Meet the design standards. This design will be temperature, humidity, smoke concentration and other air quality parameters in a system, breaking the previous independent collection of a variety of parameters. It provides a good reference for the later research.
