Calculation model of fire water cannon shooting

Abstract

The invention relates to a shooting calculation model of a fire-fighting water monitor. The shooting calculation model comprises a shooting filter model and a shooting calculation model, wherein the shooting filter model is as follows: (1) a least square filter model; (2) a tracking and predicating self-adaptive filter algorithm: by combination of a least square identification algorithm and a Kalman filter, online identification and filtering can be realized, parameters a and b are obtained by identification of a filtering output result, a state transfer matrix of a target model in the Kalman filter is determined by the parameters a and b, and circulating calculation is carried out so, and the shooting calculation model is as follows: an encounter trajectory approximation method is mainly adopted, encounter water monitor future points are predicated by combination with the fire-control common method of a shipboard-artillery weapon system, and the influence of the weather condition to the reaching point of the water monitor is fully considered. The shooting calculation model has the advantages of fewer errors and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of fire protection, Background technique [0002] With the development of modern ship technology, various types of ships are used for various tasks such as maritime defense, patrol, and anti-terrorism, which put forward higher requirements for their fire safety. The fire characteristics of these places include: rapid fire development, large fire scale, and explosion hazard. Foreign countries attach great importance to the fire safety of such flammable and explosive dangerous places. For example, industrialized countries such as Japan, the United Kingdom, and Germany have formulated corresponding laws and regulations, clearly stipulating that the above places must be equipped with fire water monitor systems. The fire water monitor system is installed in a specific location and cooperates with the fire protection system to quickly extinguish the fire through remote control according to the needs of the firefi...

AI Technical Summary

Problems solved by technology

[0004] Existing fire water cannons are divided into control water cannons and remote control water cannons. When uncontrollable water cannons shoot at the target, the deviation is large and the accuracy is low, and it is impossible to strike the target precisely; the remote control water cannon can control the water cannon through the control system It is used for fire extinguishing. Generally, there is no fire control system, and the accuracy is not high, especially affected by wind speed and wind direction.
