A gnss and ins combined navigation precision guidance fire extinguishing bomb device

Abstract

The invention provides a GNSS and an INS combined navigation accurate guidance fire extinguishing bomb device. The fire extinguishing bomb device comprises a fire extinguishing bomb loading cabin anda guidance control cabin; the guidance control cabin comprises a guidance combined body, wherein the guidance combined body comprises a structural component and an information processing unit; the information processing unit comprises a navigation, guidance and control processing unit, wherein the navigation, guidance and control processing unit comprises a micro-inertia measurement module, a satellite navigation module, an embedded combined navigation information processing module, a guidance information processing module and a communication controller module; and the satellite navigation module is used for receiving a global navigation satellite system (GNSS) information, and the embedded combined navigation information processing module is used for receiving inertial measurement unit information and satellite navigation information. The fire extinguishing bomb device adopts the GNSS / the INS combined navigation for accurate guidance, a flight path and a throwing point can be accurately controlled, complete information feedback and control functions are provided, and the comprehensive performance is excellent.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a fire-fighting bomb device that uses GNSS and INS combined navigation to accurately control the flight and throwing of fire-fighting bombs, has fast response and excellent comprehensive performance. Background technique [0002] Forest fire is a natural disaster, the most dangerous enemy of the forest, and the most terrible disaster of forestry. It will bring the most harmful and destructive consequences to the forest. However, great progress has not yet been made in forest fires. Forest fires are listed by the United Nations as one of the eight natural disasters in the world and one of public emergencies. The three-dimensional forest fire that has become a disaster spreads quickly and causes great harm. In order to control the fire in time and avoid greater losses, it is almost the only means to use aviation fire extinguishing. [0003] Domestic and foreign aviation fire...

AI Technical Summary

Problems solved by technology

[0003] Domestic and foreign aviation fire extinguishing can be divided into fixed-wing fire-fighting aircraft and fire-fighting helicopters according to the different fire-fighting platforms. Fixed-wing fire-fighting aircraft are generally equipped with water tanks and other equipment, which are loaded with fire extinguishing agent or water, and fly over the fire field to throw fire. Fire-fighting helicopters generally use buckets (hanging bag) fire extinguishing, hanging bucket (hanging bag) under the aircraft, with fire extinguishing agent (water or chemical fire extinguishing agent) inside for fire extinguishing, the disadvantage of this type of fire extinguishing is that it is greatly affected by aviation conditions, and it is not suitable for remote and terrain The practical problem of forest fire extinguishing in complex areas, and it is impossible to achieve remote control and slow response; in addition, there are still fire extinguishing methods that use aircraft to throw fire extinguishing bombs. In recent years, long-distance forest fire extinguishing bombs have been regarded as an effective means of fire extinguishing, and have attracted the attention of various countries. , this type of fire extinguishing can not be limited by the fire extinguishing conditions, and can also achieve rapid response. The disadvantage is that the fire extinguishing bomb lacks an accurate navigation structure, and its running trajectory and throwing point cannot be accurately controlled. At the same time, it lacks information feedback and control functions. Overall performance is not ideal
