"基于单片机的火灾防盗监控系统设计与仿真-毕业论文"

With the social development, single-family economic accumulation has increased, and people have paid more attention to the prevention and control of household disasters. Currently, household disasters mainly manifest in two aspects, fire and theft, so preventing and monitoring these two situations has become the focus of home disaster prevention. This paper designs a simple fire and theft prevention system based on this social phenomenon. This paper is divided into two parts for design. The first part is a fire monitoring system based on AT89S52 single-chip microcontroller, which can timely detect system faults and the presence of fire in the environment. Once a fire occurs, it will sound and light an alarm and take effective measures to control the development of the fire, extinguishing it in its early stages to ensure personal and property safety and minimize losses. The second part is an anti-theft alarm system based on AT89C51 single-chip microcontroller, which integrates sensor detection technology, intelligent control, and radio technology. This paper separately carries out hardware circuit construction and software program design for these two parts, and finally tests the software. The main modules are simulated using Protues software. Keywords: single-chip microcontroller, sensor, fire, access control, Protues.
