基于CAN总线的消防联动控制系统设计

Design of Fire Fighting Linkage Control Based on CAN Bus

本文提出一种基于CAN总线的大规模玻璃窗建筑消防联动控制系统的设计。该系统用CAN总线实现通信,根据外部环境的信号,实现电动窗消防通风控制。系统利用烟雾、风雨传感器采集外部环境的信号,将采集的信号送给STM32微处理器分析、处理,然后通过CAN总线传递给其它节点或者PC机。系统可以联网对电动窗进行控制,检测各个节点的状态,实现对各个节点的群控、点控。每个节点还可以通过检测到的外部环境信号自动地控制,例如电动窗的开关状态。当然每个节点必须有相应的按键,实现对节点的手动控制,而且手动控制的优先级应该最高,保证系统的安全性。

This paper presents a design of fire control system based on CAN bus. It adopts CAN bus to communicate.According to the external environment of the signal, it controls the power window. The system collects the signal of the external environment of, then sends it to the STM32 microprocessor for analysis and processing, and then transmits it to other nodes or PC.The system can control the power window ,detect the status of each node, and realize the group control and point control.According to the environment signal ,each node can also automatically control the switching status of the power window.Of course, each node must have a corresponding key to achieve the manual control, and manual control should have the highest priority to ensure the safety of the system.
