基于51单片机和CAN总线的延伸报警系统的研制

Research & Development of the extend alarm system based on CAN bus and MCU51

本文给出一种以51单片机为控制核心,以CAN总线为通信纽带的延伸报警系统,该系统能够实时监测现场环境中多路报警信号并根据预设规则发出声光报警,若在规定时间内报警未得到有效处理,则将报警信号延伸到指定位置。此外,系统还能实现自我检测,值班人设置、显示等功能。整个系统结构简单、稳定可靠、功能齐全。

This paper gives an extended alarm system, in which is used MCU51 as the main micro-controller and the CAN bus as communication link. Multiplex real-time alarm signal can be responded by sound and light by predetermined rules, and if the alarm signal is not handled effective within a scheduled time, the signal will be extended to the specified location. Other functions such as watcher setting and display are also included in this self-detection system. This system stable and reliable, fully functional.
