Building intelligent fire alarm control system and method

Abstract

The invention belongs to the technical field of fire alarm, and discloses a building intelligent fire alarm control system and method. The building intelligent fire alarm control system comprises a fire detection module, a life detection module, an alarm module, a camera shooting module, a central control module, a cut-off module, an evacuation module, an emergency fire-fighting module, an elevator forced landing module, a channel door detection module, a fire safety evaluation module and a display module. According to the system and method, the channel door detection module is used for automatically monitoring the state of a fire-fighting channel door in real time according to a visual identification algorithm, and the patrol by the cleaning and security personnel and the like does not need to be carried out, so that the labor cost is reduced, and the monitoring efficiency of monitoring the state of the fire-fighting channel door is improved; meanwhile, a simulated annealing algorithmis used for searching for a strategy through the fire safety evaluation module so as to find an optimal structure of the bayesian network; and a bayesian estimation method is adopted, and a safety risk assessment result is obtained through analysis through an updated bayesian network analysis tool.

Description

technical field [0001] The invention belongs to the field of fire alarm technology, in particular to a building intelligent fire alarm control system and method. Background technique [0002] With the improvement of people's quality of life. The importance of fire safety is becoming more and more prominent due to the gradual upgrading of decoration and decoration, the increase of electrical equipment, the increase of high-rise and super high-rise buildings, and the rapid expansion of the scale of mass gathering places such as shopping malls and supermarkets. With the development and maturity of intelligent building technology. More and more new buildings adopt intelligent fire protection system. It consists of two parts, one part is the automatic fire alarm system, that is, the perception and central system, which is like the human facial features and brain; the other part is the linkage fire extinguishing system, that is, the execution system, which is like the human limb...

AI Technical Summary

Problems solved by technology

[0004] The opening and closing status of the fire doors in the existing building intelligent fire alarm control system can only be checked by security personnel patrolling, which is prone to missed inspections, untimely inspections, and unmanned inspections at night, and cannot guarantee safety in an all-round way for 24 hours; at the same time, The existing safety risk assessment methods, including those based on basic statistics, empirical judgments, and large number calculations, have poor real-time performance and low accuracy. Therefore, they cannot meet the safety risk assessment needs of the existing fire protection system

[0005] In the prior art, the clarity of the image collected at the fire scene is insufficient, which is not conducive to the accurate and true collection of the fire scene; in the prior art, the life information cannot be accurately collected, prolonging the detection time, and wasting precious rescue time; in the prior art, there is no It is conducive to the display of images and data information at the fire scene, and cannot guarantee the accurate acquisition of the collected fire conditions, which is not conducive to the development of rescue work
