Intelligent method and system for monitoring hydrant's safety state

Abstract

The invention discloses an intelligent method and a system for monitoring a hydrant's safety state. The method is performed through the following steps: 101) acquiring the measuring information of all sensors and conducting time synchronization processing to all acquired measuring information, wherein the measuring information includes water pressure inside a hydrant well, the inclination angle of a well cover, or environmental brightness inside the well; 102) adopting principal component analysis to degrade the dimensions of the measuring information after time synchronization and extracting the characteristic vectors of the dimension degraded space in the same process, according to the values of the characteristic vectors, picking a plurality of the characteristic vectors as the characteristic vectors for current hydrant's safety state judgment; 103) utilizing historical data to learn the relationship between the characteristic vectors and the safety state so as to establish a machine learning model; and 104) based on the characteristic vectors processed in step 102) and by combining with the SVM recognition function built in step 103), identifying the current safety sate of the hydrant.

Description

technical field [0001] The invention belongs to the fields of information technology, automatic control and electronic technology, and specifically relates to realizing the judgment of the safety state of the current fire hydrant by constructing an intelligent identification model for the safety state of the fire hydrant, so as to assist management personnel to conduct scientific and effective supervision and maintenance, and to ensure Availability of the fire protection system. Background technique [0002] The municipal fire hydrant is an important part of the urban fire protection system, and it shoulders the important mission of quickly providing water for fire nozzles and fire trucks to meet the fire water supply. However, at present, the supervision of the fire protection system mainly adopts the method of regular inspection, which lacks scientific and efficient supervision methods. Phenomena such as theft of important components of fire protection facilities, damage a...

Problems solved by technology

[0003] At present, the safety state of the fire protection system is mainly judged by setting a simple threshold. There are problems such as false positives in safety state identification, high false alarm rate, and rough classification of safety state. How to accurately identify safety state is very important for improving The intelligent control level of fire hydrants is of great significance
