Abstract

The invention discloses a building fire alarm classification method and system, and the method comprises the following steps: S1, obtaining the alarm equipment, alarm time and alarm place of a to-be-classified fire alarm in real time, and collecting the log data of the fire alarm in a fire alarm system; S2, performing statistics on associated data of the alarm equipment in the log data in combination with the obtained alarm time and place to obtain characteristics of the fire alarm; and S3, standardizing the obtained fire alarm features, inputting the standardized fire alarm features into a pre-trained building fire alarm classification model, and dividing the fire alarm into a fire-alarm-like alarm and a fault alarm. Through the steps above, the type of the fire alarm can be quickly judged; therefore, under the condition of limited fire-fighting conditions, managers of the fire alarm system can determine the fire alarm processing priority according to the types of the fire alarms, preferentially process the fire alarms, the classification speed is high, the false alarm rate of the fire alarms can be rapidly reduced, and the managers can be helped to reasonably allocate limited fire-fighting resources.

Description

technical field [0001] The invention belongs to the technical field of fire alarm data analysis, and more specifically relates to a method and system for classifying building fire alarms. Background technique [0002] Fire detectors are an important part of the fire monitoring system. However, in fire alarms, there are often a large number of false alarms in fire detectors, and the false alarm rate is high. In order to solve the problem of high false alarm rate of fire detectors, scholars at home and abroad have carried out related research on how to reduce the false alarm rate of detectors. A detector of composite fire characteristic parameters that combines smoke with other fire characteristic parameters (gas, temperature, video surveillance, etc.); the other type is through the analysis of the particle size distribution characteristics of fire smoke and non-fire aerosols, through three-stage detection to exclude false alarms caused by non-fire aerosols. However, the two...
