Multiple-redundancy variable master-slave fire alarm monitoring system and method

Abstract

The invention relates to a multiple-redundancy variable master-slave fire alarm monitoring system and method. The multiple-redundancy variable master-slave fire alarm monitoring system solves the problems that a monitoring system in the prior art is weak in real-time performance, is free of key prevention and control differentiation, and fails to work easily when a fault occurs. The system comprises a plurality of control nodes, a master monitoring master computer, a database and a node configuration terminal. Each control node comprises a controller module, a double-redundancy network module, a USB module, a storage module and a fire monitoring module. Each double-redundancy network module is provided with two network interfaces, each network interface is connected to one network exchange unit, the node configuration terminal is connected with the USB module of each control node, the database is connected with the node configuration terminal and the master monitoring master computer respectively, and the master monitoring master computer is connected with the two network exchange units respectively. The system can automatically adjust master-slave relationships according to fault situations and automatically switch the network interfaces and the network exchange units, and therefore the reliability and stability of key systems like the fire alarm monitoring system are greatly improved.

Description

technical field [0001] The invention relates to a fire monitoring technology, in particular to a multi-redundant variable master-slave fire early warning monitoring system and method with variable master-slave control and multiple backup technologies. Background technique [0002] With the rapid development of information technology, fire early warning and monitoring technology has also developed rapidly. Various types of monitoring devices and sensors emerge in an endless stream, but the control mode of the entire monitoring system is still generally single, that is, centralized early warning in one area (single floor) When monitoring, the existing monitoring system needs to pre-set a master control node, and other slave nodes in the same area are controlled by the master control node, that is, the master control node actively initiates polling commands, and other slave nodes respond to the master control node in turn The control instructions are finally centrally processed...

AI Technical Summary

Problems solved by technology

[0007] The present invention mainly solves the problems in the prior art that the real-time performance of the monitoring system is not strong, there is no key prevention and control distinction, and faults easily lead to failure. It provides a multi-redundant multi-redundant system with variable master-slave control and multiple backup technologies. Variable master-slave fire early warning monitoring system, and monitoring method of the system
