Intelligent networking method based on fire-fighting automatic fire alarm system

Abstract

The invention relates to an intelligent networking method based on a fire-fighting automatic fire alarm system, and the method comprises a plurality of controllers which are cascaded by a tree topology structure and are in communication connection, wherein the controller at a root node is used as a head node controller for a main fire-fighting control room, and other child nodes are branch node controllers used for a secondary fire control room; each controller is matched with a networking communication ID number corresponding to the controller, and a network logic node of each controller is set through the networking communication ID number of the controller and the networking communication ID number of a superior node controller networked with the controller; the message identifier of the networking communication ID number of the first node controller in all the controllers is minimum, and the message identifiers of the networking communication ID numbers of the branch node controllers are progressively increased in a hierarchical manner by taking the message identifier of the communication ID number of the first node controller as a basic level. The purposes of centralized management, unified coordination and hierarchical control are achieved.

Description

technical field [0001] The invention relates to a security system, in particular to an intelligent networking method based on an automatic fire alarm system. Background technique [0002] With the rapid development of modern society, building complexes continue to increase, building groups and communities continue to expand, fire safety work has become the primary task of these buildings, and automatic fire alarm systems are an indispensable part of buildings. The automatic fire alarm system has its own particularity. Both industry norms and national standards stipulate that the automatic fire alarm system needs to adopt distributed settings and monitoring management, so as to reduce the fire safety of buildings caused by the failure of the automatic fire alarm system. Therefore, in practical applications, multiple fire control rooms will be set up for the same building or building group to realize distributed management. For owners or property managers, this will increase ...

Problems solved by technology

Peer-to-peer networking is adopted, that is, the system controllers are all hosts in the network, which can control all other controllers in the network to execute various instructions, and can display the terminal status information connected to all system controllers in the network, which is very important for It is very convenient to manage and control the automatic fire alarm system of a small multi-fire control room, but if it encounters a medium and large-scale project, the number of automatic fire alarm system controllers is large (the national standard requires that the number of terminal points of a controller loop should not exceed 3200 points) , the whole system will become complicated and difficult to run. First, the network communication is easy to be blocked. Second, the hardware resources of the system controller cannot meet the various communication data processing and linkage computing requirements in the network, so the peer-to-peer network can only meet small projects. ;Adopt the master-slave network networking method. In this network, one controller is required as the master, and the other controllers are all slaves. The master can control all slaves to execute various commands and display the status information of all slaves in the network. , and the status information of all terminals connected to the slave machine, which can well realize the system management mode of centralized management and unified control; but if the host machine fails or is abnormal, the entire system will be paralyzed, which will bring great harm to the fire safety of the building. great risk
