Design and Implementation of Fire Prevention and Anti-Theft Alarm System Based on Single-Chip Microcomputer

Abstract

With the advancement of the times, the living conditions of people have improved significantly, and high-rise buildings and comprehensive buildings have risen from the ground. Once these buildings are caught in a fire or theft, they will cause great losses to people's life safety and property safety. There are many alarms on the market that solve security risks, but their functions are relatively single and the cost is high. This paper designs a fireproof and anti-theft intelligent alarm system based on a microcomputer to address the issues, using a smoke sensor, a temperature sensor, a pyroelectric infrared sensor to achieve fireproof and anti-theft functions. This paper analyses the requirements and the hardware circuit module of the fire and anti-theft system, designs the system software, and introduces the software design ideas. Based on simulation software, tests were carried out to verify the feasibility of the proposed design. The fireproof and anti-theft system in this paper can detect the leakage of combustible gases, the sudden rise in temperature and the function of human body intrusion, and automatically alarm. The system in this paper has low cost and can expand the function, which helps to protect people's lives and property safety, and has high practical significance.
