基于单片机控制的光电式烟雾感应报警器的设计

The development of photoelectric smoke sensor alarm system based on Sonix MCU control

目前国内多侧重于大型场所的大型火灾报警系统的研发,而在居民住宅区等小型防火单位,却需要安装廉价实用的烟雾自动报警装置,因此,我们就有必要设计开发出一种结构简单、价格低廉的数字联网烟雾报警器,以适应市场的需求。本文通过烟雾感应电路,配合单片机控制电路,设计合理的报警系统,简单易用,使单片机在烟雾报警系统中得到充分的应用。

At present the domestic focus on large areas of large fire alarm system research and development, and in the residential area of small fire units, but need to install the cheap and practical automatic smoke alarm device, therefore, it is necessary for us to design a kind of simple structure, low price digital networking smoke alarm, to meet the needs of the market. This article through the smoke sensing circuit, with the SCM control circuit, the alarm system is reasonable in design, easy to use, the single chip microcomputer in the smoke alarm system to obtain the full application.
