Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fire-fighting equipment management, and in particular to an intelligent management system for fire-fighting equipment based on image processing. Background Art
[0002] In the current intelligent management of fire-fighting equipment, early fire detection usually uses sensor perception, such as smoke detectors and temperature sensors. Smoke detectors rely on changes in the concentration of smoke particles in the air to determine the occurrence of fire and thus provide early warning. At the same time, in the management and maintenance of fire-fighting equipment, regular manual inspections and monitoring of sensor data are required to monitor the operating status of the equipment and ensure the normal operation of the fire-fighting equipment.
[0003] However, in the initial stage of a fire, smoke will not spread quickly to the location of the detector, especially in a large space or well-ventilated environment, which will cause the detector to fail to respond in time. Similarly, temperature sensors only work in the middle and late stages of a fire, that is, when the temperature rises significantly, an alarm is triggered. Relying on temperature sensors for early fire detection will miss the best time to respond. In terms of daily maintenance, manual inspections are relatively inefficient and require a lot of time. At the same time, when a fire disaster occurs, equipment in the disaster scene and equipment with harsh installation environments (such as high-altitude fire extinguishers, sensors in pipelines, etc.) are difficult to inspect, take a long time, and cannot detect problems in time. Therefore, there is an urgent need for an intelligent management system for fire equipment based on image processing to solve such problems. Summary of the invention
[0004] To this end, the present invention provides an intelligent management system for fire-fighting equipment based on image processing to overcome the problems in the prior art that the sensor perception effect is delayed and fire scenes cannot be warned in time; manual inspection efficiency is relatively low, and the inspection of equipment in disaster scenes and equipment in harsh installation environments is difficult and time-consuming, and problems cannot be discovered in time.
