"基于单片机的家庭火灾防盗监控系统设计与仿真"

Accumulating more and more, people are paying increasingly attention to the prevention and control of household disasters. Currently, household disasters mainly manifest in two aspects: fire and theft. Therefore, the prevention and monitoring of these two situations have become the focus of household disaster prevention. This paper is based on this social phenomenon designed a simple fire and theft prevention system. The design is divided into two parts. The first part is a fire monitoring system based on the AT89S52 single-chip microcomputer, which can timely detect system failures and whether there is a fire in the environment. Once a fire occurs, it will sound and light alarm, and take effective measures to control the development of the fire, extinguish the fire in the bud state to ensure the safety of personal and property and minimize losses. The other part is a theft alarm system based on the AT89C51 single-chip microcomputer, which integrates sensor detection technology, intelligent control, and radio technology. This paper constructs hardware circuits and designs software programs for these two parts separately, and finally tests the software, using Protues software for simulation of the main modules. Keywords: single-chip microcomputer, sensor, fire, door control, Protues.
