Internet of things cooperative linkage fire extinguishing control method and system for electrical cabinet cluster

By installing non-pressurized perfluorohexanone fire extinguishing devices and composite detection nodes within the electrical cabinet cluster, a dual-mode Internet of Things collaborative communication network was constructed. This enabled real-time acquisition of multi-dimensional environmental characteristic data and dynamic fire situation assessment, solving the problems of delayed fire early warning and cross-cabinet spread in electrical cabinets, and improving the reliability and anti-spread capability of the fire protection system.

AI Technical Summary

Technical Problem

The existing electrical cabinet fire protection system has a single detection dimension, resulting in delayed early warning. It lacks a clustered collaborative mechanism to prevent the fire from spreading, and it is easily paralyzed under strong electromagnetic interference and power outage conditions, making it unable to effectively prevent the fire from spreading across cabinets.

Method used

Non-pressurized perfluorohexanone fire extinguishing devices and composite detection nodes are deployed within the electrical cabinet cluster to construct a dual-mode Internet of Things collaborative communication network. Through multi-dimensional environmental characteristic data and dynamic fire situation analysis models, a four-level fire early warning system is achieved, and a perfluorohexanone protective air curtain is formed between the electrical cabinet clusters to block the spread of fire.

Benefits of technology

It enables early warning and precise location fire suppression for electrical cabinet fires, improves the rate of fire spread prevention across cabinets, ensures the reliability of the system under strong electromagnetic interference and power outage conditions, and avoids false alarms and missed spraying.

Abstract

The application discloses an Internet of Things cooperative linkage fire extinguishing control method and system for electrical cabinet clusters, and relates to the technical field of Internet of Things control and fire-fighting automation; a dual-mode Internet of Things communication network is constructed by deploying a non-pressure-stored perfluorohexanone fire extinguishing device, a composite detection node and a passive temperature-sensing magnetic power generation node in an electrical cabinet; a four-level early warning is output by inputting a dynamic research and judgment model with a target feature vector generated by real-time collection of multi-dimensional features and combined filtering and denoising; when a fire is determined to occur, the target cabinet triggers quantitative release of perfluorohexanone; adjacent electrical cabinets are identified according to a physical position topology matrix, and the adjacent cabinets are controlled to objectively lower the early warning threshold or preventively release perfluorohexanone quantitatively, and the high-density sinking property of perfluorohexanone is utilized to form an inert protective air curtain in the bottom cable trench; the application breaks through the limitation of single-cabinet isolated defense, realizes early warning, cross-cabinet spread blocking and passive redundant fire extinguishing under a power-off working condition, and improves the fire safety resilience of large-scale electrical cabinet clusters.
