Automatic tracking and positioning fire water monitor and automatic tracking and positioning jet flow fire-extinguishing method

Abstract

The invention provides an automatic tracking and positioning fire water monitor and an automatic tracking and positioning jet flow fire-extinguishing method. The automatic tracking and positioning fire water monitor comprises a base, a support, a shell, a fire water monitor body, an infrared thermal imaging sensor, a processor, a water pump electric control valve, a horizontal stepping motor and a longitudinal stepping motor. The processor draws the coordinates of a thermal image in real time and judges the coordinates of the kindling point according to a preset temperature threshold value, and the thermal image is sent by the infrared thermal imaging sensor in real time. The fire water monitor body is positioned to the coordinates of the kindling point rapidly and tracks the coordinates of the kindling point in real time until the processor controls the water pump electric control valve to be opened and the fire water monitor body sprays water. The automatic tracking and positioning fire water monitor has the advantages of being scientific in design, rapid and accurate in positioning and capable of realizing movable fire tracking. The use method includes the steps of (1) clearing, (2) scanning, (3) judgment, (4) fire extinguishing, (5) water stop detection, (6) fire-extinguishing finishing and the like, and has the advantages of being simple, efficiency, capable of realizing movable fire tracking, complete in scanning coverage and capable of preventing detection omission.

Description

technical field [0001] The invention relates to a fire-fighting equipment, in particular to an automatic tracking and positioning fire-fighting water cannon, and also relates to an automatic tracking and positioning jet fire extinguishing method. Background technique [0002] Most of the commonly used automatic tracking and positioning fire water monitors on the market use the infrared sensor to coordinate with the vertical and horizontal narrow slits to locate the fire point crosswise. When scanning, first scan in the circumferential direction to determine the circumferential position of the fire point, and then Then scan longitudinally to determine the longitudinal position of the ignition point, so as to achieve accurate positioning, but the actual narrow gap covers a range of several meters wide when it is tens of meters away, so the positioning error of the fire water monitor using the traditional narrow gap technology reaches several meters , the farther the distance i...

[0002] Most of the commonly used automatic tracking and positioning fire water monitors on the market use the infrared sensor to coordinate with the vertical and horizontal narrow slits to locate the fire point crosswise. When scanning, first scan in the circumferential direction to determine the circumferential position of the fire point, and then Then scan longitudinally to determine the longitudinal position of the ignition point, so as to achieve accurate positioning, but the actual narrow gap covers a range of several meters wide when it is tens of meters away, so the positioning error of the fire water monitor using the traditional narrow gap technology reaches several meters , the farther the distance is, the greater the error is; in addition, the flame spreads faster in a fire, and the position of the flame will change at any time, resulting in the phenomenon of fire drift. position, resulting in a deviation between the actual fire position and the positioning water spray position, the fire extinguishing failed, and the fire water cannon was useless
