A Horizontal Positioning Algorithm for Automatic Tracking and Positioning Jet Fire Extinguishing Device

Abstract

The invention belongs to the field of fire-fighting water cannons, and in particular relates to a horizontal positioning algorithm for an automatic tracking and positioning jet fire extinguishing device. In order to solve the problem of inaccurate horizontal positioning, the fire cannot be extinguished in time, which reduces the fire extinguishing efficiency at the initial stage. The invention intends to make up for the horizontal installation error of the water cannon, the manufacturing error and assembly error of mechanical parts, the individual difference of the pyroelectric infrared sensor, and the horizontal positioning error caused by the unstable output signal of the sensor caused by the change of ambient temperature through the horizontal positioning algorithm.

Description

technical field [0001] The invention belongs to the technical field of automatic fire extinguishing of fire fighting equipment, and in particular relates to a horizontal positioning algorithm of an automatic tracking and positioning jet fire extinguishing device. Background technique [0002] Compared with traditional spraying technology, intelligent fire water cannon is an intelligent fire protection product produced by high-tech technology. It integrates computer technology, red and ultraviolet sensing technology, mechanical transmission technology and image transmission technology. It has all-weather and automatic active detection of the monitored area. Once a fire is found, it will immediately complete the positioning and automatically spray the fire to extinguish the fire at an early stage. If there is re-ignition, it can be restarted. After the fire is extinguished, the device automatically closes the valve and stops spraying water automatically. A highly intelligent ...

Problems solved by technology

[0003] At present, the automatic tracking and positioning jet fire extinguishing device used in the market uses horizontal reciprocating swing to sweep water to extinguish the fire after the fire source is located. Due to the horizontal positioning error, the impact force of the water source is not fully utilized to strike the fire source. The problem of the spread of the fire source, so the fire source cannot be extinguished in time, which reduces the fire extinguishing efficiency in the early stage

[0004] Comprehensive analysis The first reason for the inaccurate horizontal positioning is that the product itself is caused by the manufacturing error of mechanical parts, assembly error, and individual differences in infrared sensors. Most manufacturers calibrate the error before leaving the factory.

The second reason is that in the actual fire scene, there are problems of nozzle installation level errors, large flames and small flames, and the distance between the flame position and the water cannon. This situation is generally calibrated through complex program classification. Calibrate once, calibrate once near, calibrate once when the flame is large, and calibrate once if the flame is small, so the program complexity increases and the program stability decreases

However, there will still be errors caused by some unstable factors. In order to solve the above-mentioned problems, the present invention has invented a positioning algorithm
