智能火灾报警联动系统的设计研究

Research of Intelligent Fire Alarm and Linkage Control Systems

针对市场上火灾报警系统布线复杂,报警联动控制系统数学模型不够完善的实际问题,提出了运用嵌入式多CPU控制、总线探测、总线控制的方案。在系统设计中引入物理结构和逻辑结构的概念,使系统在布线时不用考虑系统物理结构和火灾显示器的分布影响,只需能满足系统逻辑结构的要求,从而大大简化系统布线复杂度。同时为系统建立火灾报警联动控制的数学模型,提出了模型中两种关键参数-系统权重和误报指数。针对不同的监控现场只需设定相关参数便可实现,系统可以现场编程实现总线探测以及联动控制模型。在监控中采用多级网络监控的方式,实现远程监控的功能。

Fire alarm systems on the market are too complex and their linkage control module is still imperfect.To solve this problem,a method based on several embedded CPU and bus inspecting is presented.The concepts of physical structure and logical structure are introduced,so that the distributing influences of physical structure and fire display can not be considered during the system connection.It simply needs to meet the requirement of the logical structure.Thus,the system is much simpler.The mathematic model of...
