Problems solved by technology

At this stage, the fire extinguishing method for offshore platforms adopts the method of linkage fire extinguishing. When there is a fire point, the fire protection system of the entire offshore platform will start. However, the existing system cannot quickly and accurately find the fire point and quickly extinguish the fire.

Embodiment Construction

[0022]The present invention is a kind of marine platform automatic foam fire extinguishing vehicle rapid and accurate fire extinguishing method, comprising the following steps:

[0023] Step 1: Choose any O on the FPSO deck s Establish the spatial coordinate system O s X s Y s Z s , select any direction as X on deck level s Axis positive direction, select one on the same plane as X s The vertical direction of the axis is Y s Positive axis, Z s Axis with X s Axis, Y s The axis is perpendicular and perpendicular to the deck horizontally facing upwards in a positive direction;

[0024] Step 2: Install three thermal cameras on the FPSO deck (the thermal camera is available on the market) and obtain the spatial position point coordinates of the center point of the lens of the three thermal cameras, which are recorded as A(X). 1 ，Y 1 ，Z 1 ),B(X 2 ，Y 2 ，Z 2 ),C(X 3 ， Y 3 ，Z 3 ), and the coordinates of the three spatial location points are entered into the computer of the FPSO general con...

Abstract

The invention discloses a rapid and accurate fire extinguishing method for an automatic foam fire extinguishing vehicle in an ocean platform, which comprises the following steps: establishing a space rectangular coordinate system on an FPSO deck, and calculating the position coordinates of a fire point through the space position coordinates of three thermal cameras on the deck and the distances from the cameras to the fire point; the shortest path from the foam fire extinguishing vehicle to the fire point is calculated according to the position coordinates of the fire point, the position coordinates of the spraying center point of the foam gun of the foam fire extinguishing vehicle and the path information, and the foam fire extinguishing vehicle runs along the shortest path to a certain distance away from the fire point and stops; a rectangular plane coordinate system is established on a plane passing through a spraying center point and a fire point in a stop state of the foam gun, a motion trail equation of foam sprayed from the spraying center point of the foam gun to the fire point is established by utilizing the Newton second law, and the angle required by the foam gun is calculated by the motion trail equation. According to the invention, accurate positioning and rapid fire extinguishing can be realized, and the fire extinguishing requirements of different fire points are met.

Description

Technical field [0001] The present invention relates to a rapid and precise fire extinguishing method, in particular to a rapid and precise fire extinguishing method of an automatic foam fire extinguishing vehicle within an offshore platform. Background [0002] The FPSO offshore platform is mined in flammable and explosive natural gas, the fire prevention level on the marine platform is higher, once the fire occurs, the fire area is more dangerous, so it is important to accurately find the location of the ignition point and quickly extinguish the fire. At this stage, the fire extinguishing method of the marine platform is a linkage fire extinguishing method, after there is a fire point, the fire protection system of the entire marine platform will be activated, but the existing system cannot quickly and accurately find the ignition point and quickly extinguish the fire. Contents of the Invention [0003] Object of the present invention is to overcome the shortcomings of the pri...
