Embodiment Construction

[0041] The two parts of fire monitoring and fire extinguishing belong to the category of fire protection and are related to each other. Therefore, the present invention utilizes computer vision technology to integrate the two into one system to realize closed-loop control of fire fighting and fire extinguishing, and to realize intelligent fire monitoring and fire extinguishing.

[0042]The system consists of a computer and several substations, and the computer realizes centralized management and distributed control. The computer and the substation are connected through the bus (or network) to realize information sharing. The number and location of sub-stations are based on the area of ​​the fire monitoring area and the characteristics of the objects (such as equipment, etc.) in the area, as well as the location of the key fire prevention areas that are prone to fire. For key fire prevention areas, sub-stations can also be added as needed. Each substation takes the MPU embedd...

Abstract

The invention relates to a monocular vision technique based fire monitor control method for adjusting relative positions of a fire point and a water-drop point, which belongs to the technical field of fire monitoring and self-extinguishing. By using a method for controlling a pitching angle and a horizontal angle for a plurality of times respectively in sequence, the fire monitor control method solves the problem of adjusting the relative positions of the fire point and the water-drop point in a three-dimensional space by using a two-dimensional image so that the water-drop point of the fire monitor can track the changes of the position of the fire point in real time so as to provide a condition for the self-extinguishing in a large space.

Description

technical field [0001] The fire monitor control method for adjusting the relative positions of a fire point and a water drop point based on monocular vision technology of the present invention belongs to the technical field of fire monitoring and automatic fire extinguishing. Background technique [0002] Fire is one of the most common serious disasters in human society. According to the fire statistics of the United States, Japan and the European Union in recent years, the direct economic loss of fire in developed countries accounts for 0.2% to 0.3% of the gross national product. Fire fatalities in the US are 0.0016%, in the EU 0.0013%, and in Japan 0.0012%, including many major fires. For example, the fire caused by the Great Hanshin Earthquake in Japan in 1995 killed more than 5,200 people. In 1997, a fire broke out in the holy city of Mecca in Saudi Arabia during Ramadan, killing more than 1,000 people. In June 2002, the forest fire in Arizona State, USA was out of con...
