Drone forest fire prevention

The application of forestry fire-fighting drones focuses on the early detection of forest fires in remote areas that cannot be considered by ground patrols, as well as the accurate grasp and timely understanding of various dynamic information on major forest fire scenes. It can also solve aircraft patrols. It is impossible to fly at night, smoke causes visibility to be reduced, and it is impossible to fly. As a powerful complement to existing forestry monitoring methods, drones show superiority that other means cannot match, and will be widely used in forestry fire monitoring, prevention, suppression, and post-disaster assessment.

Specific use of drones in forest fire prevention

Background introduction

Forestry is the main body of national ecological construction and plays an indispensable role in maintaining economic and social development. China has a forest area of ​​175 million hectares, a forest stock volume of 12.456 billion cubic meters, and a forest coverage rate of 18.21%. It is a forest resource country. It is also a country with frequent forest fires. How to effectively use high-tech means to solve forest resources surveys, forest fire prevention and other issues has become the top priority of forestry work. At present, many new technologies and new equipments have been applied in forest fire prevention in foreign countries. The domestic demand for applications in this area is also increasing. The investment in forest protection is gradually increasing. Satellites are used for resource surveys and forest fires. The monitoring of forest fires by the drone system is still the initial stage.

Specific use of drones in forest fire prevention

First, daily forest fire patrol

The patrol efficiency of the drone is much higher than that of the traditional manual patrol. It can complete the patrol work that many people need to carry out in a short time, and the running cost is also extremely low.

Second, the forest fire prevention process

1. Quickly locate the fire point. The forest fire is monitored by the infrared and visible light camera of the drone, and is transmitted to the ground control station in real time through the numerical control telemetry circuit. The fire point and hot spot are displayed on the digital map of the ground station, and the identification system determines whether it is a fire point, and Accurate fire point positioning is provided to provide ground fire department geographic coordinates (latitude and longitude) for the ground fire department.

2. Quickly determine the fire. When the drone is flying above the fire, data such as the contour, area, and spread speed of the fire can be transmitted back to the ground control center in real time to provide reliable information for the ground fire command, so that the fire control command department can organize and deploy quickly and effectively. Fire fighting teams to improve the efficiency of fire fighting operations and prevent casualties of firefighters.

3. Provide the best evacuation route for the fire department. The effective communication of all kinds of information not only enables the fire brigade to quickly deploy personnel to carry out fire fighting work in key areas, but also promptly informs firefighters to evacuate dangerous areas and provides firefighters with the best evacuation route based on the fire image data.

Third, artificial precipitation

The UAV system can be used for artificial rain enhancement. It is easy to use, easy to maneuver, easy to put in, and has no risk of personnel safety. Therefore, it is especially suitable for artificial precipitation in forest fire prevention operations. The drone carries a total of 10 additional rain flames, which are mounted on the belly and the landing gear through the pylon. A certain flame is ignited in flight and controlled by the ground remote control, and the state of the flame is displayed by the telemetry information. Each time, multiple cigarette tubes can be ignited at the same time. According to the relationship between the amount of silver iodide and the working area in the man-machine artificial rainfall operation, the silver iodide content of the 10 increasing flame strips can meet the requirements of the artificial rainfall operation area of ​​100 square kilometers.

Fourth, by carrying different mission loads, it can effectively improve the maneuverability and search and rescue efficiency of fire fighting work.

1. Uncooled dual-channel infrared imager for drones: can penetrate the smoke for personnel search and rescue; real-time image transmission system and ground control system can effectively confirm the position of people with key concerns such as personnel and dangerous goods; With regional temperature difference display function; with regional maximum temperature positioning function; with full infrared, video image, dual video channel overlay function;

2. High-resolution digital camera: When the observation object is 100 meters, the geophysical prospecting accuracy is ≤10mm, which can effectively find the details of attention; when taking photos of the area, it can form a positive orthophotometric image of the area with strong phase, so that the task decision, Disaster management and post-disaster reporting are more intuitive and effective.

3. High-definition digital video camera: The real-time image transmission system and the ground control system can effectively assist the staff to lock and gaze at the attention of things.

4. Material delivery equipment: through integrated probes, reels, warehouses, ladders, etc., can carry out horizontal transportation of materials, line traction, leaflet delivery, material delivery, etc.

5. Other: Broadcast, lighting, communication relay
