Building fire scene monitoring system based on unmanned aerial vehicle and implementation method thereof

Abstract

The invention discloses a building fire scene monitoring system based on an unmanned aerial vehicle and an implementation method thereof, and the system comprises the unmanned aerial vehicle, a holder structure disposed on the unmanned aerial vehicle, a high-altitude displacement telemetering device connected to the holder structure, and a corresponding signal conversion circuit and a voltage stabilizing circuit, a displacement beacon arranged outside the building, a temperature sensor, a displacement sensor and a low-delay communication device which are arranged inside the building, and a monitoring and early warning terminal for receiving and processing signals. A 3D digital model is established for the high-risk fire building, and a building fire collapse database is established through simulation analysis; the displacement value of each monitored part is compared with a displacement threshold value in a database, and early warning processing is carried out. According to the invention, a mode of combined monitoring inside and outside the building is adopted, the unmanned aerial vehicle is adopted to carry the high-altitude displacement telemetering device above the building for monitoring, and monitoring information is transmitted in a low-delay manner, so that effective monitoring of a building fire scene is realized.

Description

technical field [0001] The invention belongs to the technical field of fire fighting and rescue, and in particular relates to a building fire site monitoring system based on an unmanned aerial vehicle and an implementation method thereof. Background technique [0002] With the rapid development of my country's economic construction, the fire risk of buildings remains high. Once a fire breaks out in a building, if it is not extinguished in time, it may lead to the collapse of the building, which may cause heavy losses of people's lives and property. The collapse of buildings under fire is random, and there are many kinds of building component materials. At present, with the extensive application of new materials such as steel and plastic, different forms of deformation and collapse will appear under different fire conditions, and some are localized. Some of the damages are caused by partial collapse and total collapse, and some are the rapid and comprehensive collapse of the ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no effective method for monitoring and early warning of building collapse under fire. Non-contact monitoring technology usually uses optical methods, but it is easily interfered by high-temperature smoke from fires. In addition, radars are deployed on the ground around buildings in fire for monitoring. , but this method can only monitor the displacement of a few points, and in order to ensure the displacement accuracy of monitoring, it is necessary to place the radar very close to the burning building, which has a high risk in actual operation. Early warning often lacks corresponding technical means
