基于单片机的火灾防盗监控系统设计与仿真

accumulating more and more, and people are paying more and more 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 and designs a simple fire and theft prevention system. The paper is divided into two parts. The first part is the fire monitoring system based on the AT89S52 single-chip microcomputer, 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, eliminating the fire in its infancy to ensure the safety of life and property and minimize losses. The second part is the theft alarm system based on the AT89C51 single-chip microcomputer, which integrates sensor detection technology, intelligent control, and wireless technology. This paper builds hardware circuits and designs software programs for these two parts and tests the software, using Protues software for simulation of the main modules. Keywords: single-chip microcomputer, sensor, fire, door control, Protues.
