High-rise building fire positioning system and high-rise building fire positioning method

Abstract

The invention provides a high-rise building fire positioning system and a high-rise building fire positioning method. The system comprises a detector, a two-dimensional adjusting base, an information fusing and processing module and a human-computer interaction module. The detector is composed of a laser range finder, an infrared thermal imager and a visible light camera. The two-dimensional adjusting base adjusts the optical axis of the detector to make the optical axis point to a fire site according to an instruction of the human-computer interaction module. The information fusing and processing module analyzes acquired distance information, an infrared image and a visible light image of the fire site to get the line-of-sight angle and actual distance information of the fire site, and sends the line-of-sight angle and the actual distance information of the fire site to the human-computer interaction module. The human-computer interaction module is used for sending an instruction for adjusting the optical axis of the detector to make the optical axis point to the fire site to the two-dimensional adjusting base, and displaying the information and the images. With the system and the method of the invention, accurate guidance information can be provided for a fire fighting and rescue system, accurate ignition location and distance information can be provided for the launch of a fire extinguishing bomb, and the ignition position can be located quickly and accurately. The system and the method are applicable to positioning of a fire characterized by heavy smoke, large distance, fast spread and high floor.

Description

technical field [0001] The invention relates to a high-rise building fire positioning system and method. Background technique [0002] With the development of urbanization, land use in large and medium-sized cities is becoming increasingly scarce. In order to improve land utilization, urban planners regard the construction of high-rise buildings as an effective way to solve this problem. Residential buildings, commercial buildings, office buildings, and high-rise buildings for various purposes have become the first choice of urban designers and urban landmarks. In a relatively long period of time in the future, high-rise buildings will become the main form of buildings in large and medium-sized cities, and residential buildings will also appear in the form of high-rise buildings. However, while saving land, these high-rise buildings also bring great potential safety hazards. Judging from many building fire accidents that have occurred in recent years, once a fire breaks ...

Problems solved by technology

[0005] (2) It is very difficult to put out fires in high-rise buildings

However, limited by the physical strength of the human body, firefighters can support the height of the 20th floor under the condition of equipped with equipment, but they cannot maintain the physical strength required for subsequent fire fighting work, which will cause great harm to firefighters and rescued personnel.

At the same time, it may not be able to meet the current fire extinguishing requirements of high-rise buildings.

[0008] (3) Fires in high-rise buildings last for a long time and cause great losses

Under the long-term high-temperature action, although reinforced concrete members and steel structures cannot burn, the long-term high-temperature action will cause the strength and stiffness of the material to decrease, and the building will be damaged and cracked, resulting in overall or partial collapse, causing serious property losses and casualties

A large number of household appliances, clothing and furniture are piled up in a limited space in a residential building, and a large number of flammable materials are used for decoration. After a fire occurs, it is difficult to move the materials and the property losses are serious.
