Embodiment 1

[0073] The fire hydrant safety state intelligent monitoring method and system proposed by the present invention include several major modules: a Beidou fire hydrant monitoring terminal, a communication transmission terminal, a Beidou navigation location service platform, and an alarm display terminal. The Beidou positioning monitoring terminal dynamically collects the water pressure in the fire well, the inclination angle of the manhole cover, and the ambient light brightness information in the well, and performs data preprocessing. The preprocessed data is sent to the Beidou navigation location service platform through the Beidou positioning monitoring communication terminal, Beidou navigation The location service platform uses the established support vector machine model to identify the current security status by extracting the characteristic measurement information sent by the monitoring terminal, and the identification results are displayed and pushed by the alarm display te...

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...
