摘要
本文介绍了一种用DS18B20作为测温报警元件,以CAN总线作为主干网的大型火灾温度报警系统,并围绕DS18B20详细阐述了系统的硬件实现和软件实现。较之只用单总线组成的DS18B20测温报警系统,此系统具有测点多、造价低、安装维修方便、便于扩展、可靠性高、抗干扰性强等优点。
The article describes a large -scale fire temperature alarm system, which uses DS18B20 to acquire temperature and alarm, and use CAN bus as backbone. It has many advantages such as abundant measuring points, low price, easy to set up and maintain, easy to expand, high reliability, and high interference immunity.
