基于51单片机的环境监测与防盗系统的设计(任务书,开题报告,外文翻译,论文15000字)
摘 要
随着社会的日益发展，人们长期工作和居住的室内的空气质量问题已经愈发受到大家关注。如何监测并及时对当前已经出现安全隐患的空气质量发出警告，已经成为一个急需解决的问题。本文以此为设计背景，通过Protues软件进行仿真，运用C语言进行设计，不仅能解决实时监测当前室内空气质量的需求，同时还要能对当前超标的空气质量和外人的闯入作出及时的报警，通过灯光、声响以及短信的方式及时警告使用者应当注意此时的空气质量以及可能发生盗窃的情况，以保障使用者的生命健康和财产安全。
论文主要详细论述了一个基于51单片机开发的空气质量监测与报警系统的设计和实现过程。制造出了一个能实时监测当前环境中的温度、湿度、PM2.5含量以及甲醛含量的单片机系统，并且该系统能够对空气中超标的参数以及外人的闯入发出警告短信，以提醒使用者此时应该注意调整室内环境和防盗。
本文的特色在于基于专业所学知识，把传统的带有探测功能的硬件与无线通信相结合，在系统满足监测和报警的具体功能的基础上，还能通过发送短信的方式给使用者发出警告。

Abstract
With the development of society, people have paid more and more attention to the indoor air quality problems that people work and live in for a long time. How to monitor and warn the air quality which has appeared potential safety hazards in time has become an urgent problem to be solved. This paper takes this as the design background, carries on the simulation through the Protus software, carries on the design using the C language, not only needs to solve the real-time monitoring current indoor air quality demand, but also can make the prompt alarm to the current excessive air quality and the intrusion of outsiders, through the light, the sound and the short message way promptly warns the user to pay attention to the air quality at this time as well as. Theft may occur in order to protect the life, health and property safety of users.
This paper mainly discusses the design and implementation of an air quality monitoring and alarm system based on 51 single chip computer. A single-chip computer system which can real-time monitor the temperature, humidity, PM2.5 content and formaldehyde content in the current environment is developed. The system can send warning messages to the parameters exceeding the standard in the air and the intrusion of outsiders, so as to remind users to pay attention to adjusting the indoor environment and anti-theft at this time.
Based on the professional knowledge, this paper combines the traditional hardware with detection function with wireless communication. On the basis of meeting the specific functions of monitoring and alarming, the system can also send warnings to users by sending short messages. In line with professional characteristics, it also conforms to the development trend of the information age.
