家用防火防盗报警系统的设计(论文10800字)
摘要：营造一个舒适安全的家庭环境，对社会安定和人民幸福具有重大意义。目前住宅的防火防盗问题困扰着人民，主要因为防火防盗系统绝大多数是面向大型场所研发，其价格高昂操作复杂，不适合居民住宅。因此设计一款价格低廉、安全可靠的家用防火防盗系统势在必行。本文设计了一种以STC89C52单片机为核心的防火防盗报警系统，运用多个传感器对住宅环境信息进行检测，一旦探测到有人非法入侵或温度过高或天然气等易燃气体泄漏时，该系统不仅可以立马发出声光警报，而且可以发送短信提醒他家中有人入侵或发生火灾，从而确保家庭安全，降低财产损失。经实践检验，该系统稳定可靠,操作简单,灵敏度较高,适用于绝大多数的普通家庭。

Design and Development of Home Fire Alarm System
Abstract:Creating a comfortable and safe family environment is of great significance to social stability and people’s well-being.At present, fire and burglary problems in residential buildings are plagued by people.The main reason is that the vast majority of fire prevention and security systems are developed for large-scale sites. Their high prices and complicated operations are not suitable for residential buildings. Therefore, it is imperative to design a low-cost, safe and reliable home fire protection system. This paper designed a fire alarm system based on STC89C52 microcontroller and used multiple sensors to detect the environmental information of the house.Once the detection of illegal intrusion or high temperature or the leakage of flammable gas such as natural gas, the system can not only immediately send out sound and light alarm, but also send text messages to remind him of someone in the family to invade or a fire, thus ensuring family safety and reducing property damage.After practice tests, the system is stable and reliable, simple operation, high sensitivity, suitable for the vast majority of ordinary families.
