An automatic tracking and positioning jet fire extinguishing method

Abstract

The invention discloses an automatic tracking and positioning jet flow extinguishing method. A camera is used for collecting on-site video images, the water falling point position is corrected through human assistance, and remote quick positioning of a fire point is achieved on a monitoring platform of an upper computer. The method comprises the steps that a fire source signal is detected through a jet flow extinguishing device, and the center position of a fire source region is determined preliminarily and sent to the upper computer so as to control the extinguishing device to spray water for extinguishing; according to on-site real-time monitoring videos collected by the monitoring camera, whether outflow water falls in an effective range of the center position of the fire source is judged, and if yes, adjustment is not needed; if the outflow water is out of range, human-assisted positioning adjustment is conducted on the water falling point position, and the water falling point is made to be in the effective range of the center position of the fire source. By the adoption of the extinguishing method, the positioning precision of an extinguishing system is improved to a great extent, the possibility of software misjudgment is reduced, and a guarantee is provided for quick, efficient and reliable operation of the fire-fighting extinguishing system.

Description

technical field [0001] The invention can be applied to the field of fire protection, and in particular relates to an automatic tracking and positioning jet fire extinguishing method. Background technique [0002] According to the "Technical Regulations for Large-Space Intelligent Active Sprinkler System" (CECS263:2009) formulated by China Engineering Construction Standardization Association, indoor large-space places can be defined as the clearance height of civil and industrial buildings greater than 8m, and the clearance of warehouse buildings. Places with a height greater than 12m (2009C. Technical regulations for intelligent active sprinkler systems in large spaces [s] [D]), such as convention centers, shopping malls, office buildings, hospitals, airports, railway stations, libraries, gymnasiums, museums , hotels, cinemas, sightseeing towers and other large buildings. [0003] In recent years, with the rapid development of my country's economy, large-space buildings hav...

Problems solved by technology

[0009] Therefore, there is a lack of a mechanism that not only uses the live video images collected by the camera to realize the remote and fast positioning of the fire point, but also introduces the camera distortion correction into the fire point positioning system.
