摘要
阐述了分布智能式火灾报警与联动系统实验装置的研究。该装置的火灾报警控制器基于单片机最小系统设计,改善了传统的火灾报警系统点对点的多线制结构模型,采用基于二总线技术的数字编码、数字信号脉冲信号巡检机制的多节点巡回检测,有效地提高系统的抗干扰能力、解决系统低功耗、远距离通讯的要求。由多个独立的区域控制器子系统和一个集中控制器组成基于CAN总线的分布式控制式系统结构,有效地免去单一控制器大量的信号处理负担,降低系统巡检周期、提高系统运行的灵活性、实时性、稳定性和可靠性。
In this paper, a design of distributed and intelligent fire alarm and control linkage experimental device is introduced , which bawd on single - chip microcomputer, improving traditional node to node multi - lines fire alarm structure model, multi - node measurement based two - line buses adopting digital signal coding and digital pulse signal itinerating test technology, improving strong anti - interference ability and settling the problem on low power loss and super long distance commuciation. The distributed system structure impose of the multi - area controller and centralized controller can real - time comrnunicate base on CAN bus and effectively reduce the heavy load of single controller on multi - signal processing and the itinerating test cycle, meanwhile improve the system excellent flexibility, good real - time ability, high stability and reliability.
