Description

[0001] The present invention relates to the technical field of intelligent detection and alarm, and in particular to an intelligent detection and alarm system and method for emergency management. Background Art

[0002] Under existing technology, sprinklers and water pipes are usually installed in high-rise buildings to automatically spray water mist to extinguish fires when fires occur. However, regular maintenance and inspection of fire-fighting equipment may lead to personnel negligence and missed inspections, so a detection system is needed to detect fire sprinklers. However, there is a chain reaction in the failure of fire sprinklers. When the detection system fails to correctly identify the root cause of the fire sprinkler failure, if the maintenance personnel perform maintenance without understanding the actual situation, it may also bring additional safety hazards. In addition, the root cause of the fire sprinkler failure is not resolved, resulting in another failure before the next maintenance, so that the sprinkler may not work properly when a fire occurs, thereby increasing the risk of fire. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent detection and alarm system and method for emergency management to solve the problems raised in the above background technology.

When the data information fed back by the fire protection system to the fire protection system under any debugging information does not match the standard data information, it is determined that the debugging point corresponding to the debugging information has a failure, that is, the failure point, j'=1, 2, 3...J', because it is based on different debugging information. The test information is used to sort the number of fire sprinklers that are not consistent with the standard data information fed back to the fire protection system, so the types of debugging information are the same, that is, j'∈{1, 2, 3...J}; S303, the actual fault cause of the fire sprinkler is traced back through the fault association relationship and the fault point Pi"j' of the fire sprinkler ui", and the actual fault cause Y(Pi"j') corresponding to the fire sprinkler fault point Pi"j' is obtained, wherein the actual fault cause of the fire sprinkler is traced back according to the position of the fault point of the fire sprinkler in the corresponding fault association relationship, and the actual fault cause of the fire sprinkler can be obtained by tracing back in the opposite direction of the arrow "→"; by accumulating the number of the same actual fault causes corresponding to the fire fault point ui", the actual fault causes are sorted from high to low according to the accumulated number, and the fire sprinklers are inspected and maintained in turn according to the sorting results.
