"基于C51单片机的烟雾报警器设计与实现"

摘要 随着现代家庭用火和电量的增加，家庭火灾发生的频率也在逐渐上升。为了提高家庭火灾的安全性，烟雾报警器作为一种重要的安全设备被广泛应用于各种场合。本设计基于C51单片机和传感器技术开发了一款烟雾报警系统。该系统主要由烟雾传感器、C51单片机主控电路和外围设备电路组成，通过传感器实时监测环境中的烟雾浓度，并通过单片机进行数据处理和报警。本文详细介绍了烟雾报警器系统的各个组成部件，包括主控电路和外围设备电路之间的接口技术，以及软件设计方面的重点内容。 关键词：报警器、C51单片机、烟雾传感器 Abstract With the increasing use of fire and electricity in modern homes, the frequency of home fires is also gradually increasing. In order to improve the safety of home fires, smoke alarms, as an important safety device, are widely used in various occasions. This design is based on the C51 single-chip microcomputer and sensor technology to develop a smoke alarm system. The system is mainly composed of smoke sensors, the C51 single-chip microcomputer main control circuit, and peripheral device circuits. The sensor monitors the smoke concentration in the environment in real-time, and the microcontroller processes the data and triggers an alarm. This paper provides a detailed introduction to the various components of the smoke alarm system, including the interface technology between the main control circuit and peripheral device circuit, as well as the key points of software design.
