Forestry, anti-drug solution

Forestry, anti-drug solution

First,Overview

 
    China's forest resources are relatively poor, the forest coverage rate is about 13%, per capita forest area is only the world average of 1/6, but the forest fire every year, how to solve the problem of forest fire, In the heavy At present, foreign forest fire protection in the application of more new technologies and new equipment, domestic applications in this area is also increasing demand for forest protection gradually increased investment, has used the satellite for resource census, forest fire surveillance, now use UAV system monitoring of forest fire is imperative.
The low-altitude monitoring system of UAV has the characteristics of rapid operation, low cost and simple maintenance operation. It has a fast real-time monitoring and monitoring capability, and is a new type of low-level real-time TV imaging and infrared imaging fast acquisition system. In the car, people can not reach the zone of resources and environment monitoring, forest fire monitoring and rescue command has its unique advantages.
 
 
 

Second,the overall program introduced

 
1,the overall structure
 
Operators only according to the ground station tips, set the route, camera parameters, flight scale can start to do the task, and do not need manual control, the safety factor is higher! Ground control software can automatically calculate the flight space and range, but also according to the wind direction to adjust the course, set the emergency protection parameters, so that the aircraft in a variety of uncertainties to ensure maximum data security.
Airborne real-time monitoring and tracking equipment can telemetry flight trajectory, the task is automatically returned to the default location after the parachute drop.

2,2 Model Description:
 
1) Dedicated rubber band catapult take off, no need to control the hand, wide adaptability. Triangle wing rudder design, wing area large weight light, heavy load, you can carry sony rx1r2 micro single camera, pixels to 42 million.
2) fixed-point parachute, high security.
3) the overall modular, removable after the volume of conventional fixed wing smaller, easy to transport to carry. Aerospace honeycomb composites, light weight, high strength. Oil version of a task can fly 3-4 hours operating area of ​​30 to 60 square kilometers, range of 300 km range, speed 100 km, wind resistance 6 - 7 level.
4) DY-2000 automatic ejection took off, canceled the bulky catapult, easy to carry.
 
 
5) the operator simply according to the ground station tips, set the route, camera parameters, flight scale can start to do the task, and do not need manual control, higher safety factor!
6) The ground control software can automatically calculate the flying area and range, but also according to the wind direction to adjust the course, set the emergency protection parameters, so that the aircraft in a variety of uncertainties to ensure maximum data security.
Airborne real-time monitoring and tracking equipment can telemetry flight trajectory, the task is automatically returned to the default location after the parachute drop.
 
 
 
 
2,3 DY-2000 Applicable industry
 
         In addition to forest fire monitoring and forest protection, but also can be used for aerial photogrammetry, power line inspection, urban planning, land and resources survey land survey law enforcement, mineral resources development, emergency relief, flood control and drought, environmental monitoring, border surveillance, military reconnaissance and police Fire control and other industries, as well as other UAV operations can be used in special industries.
 
2,4 ground station software features
 
1) support fool pre-flight checklist, just 10 steps, 1 minute to complete the flight check. To ensure efficient, to prevent mistakes forget.
 
 
 
2) support multi-user management, each flight operation can record users, operating procedures, easy to post-analysis statistics.
3) support the automated aerial test route design, just enter the aerial photography range, select the camera model, image resolution requirements, can automatically generate aerial routes,
 
 
 
4) to support the professional zoning route planning and design, for high drop area, according to different flight height, overlap rate, a single sub-partition design routes to meet the aerial survey requirements.
5) support a variety of maps for route planning (Google, BING, etc.) can also support custom map import
6) support route preview function, can visually display the route height and terrain height difference, to ensure safety, to prevent the occurrence of mountain collision.
7) Support height protection function, can set the flight protection height, if fault, the aircraft dropped to the default value, can automatically open the umbrella to protect the aircraft.
8) support the task area multi-format import, such as kml file, excel file.
 
2,5 autopilot:
 
1) core cpu chip using the United States Motorola industrial chip, mpc565, to ensure safe and reliable, known as not crash cpu. The model cpu is widely used in aerospace, high-class car automatic control field. (Different from the ordinary civilian use of the ARM control chip - mobile phone chip, there is the risk of crash)
2) core algorithm: based on the United States Boeing's total energy control algorithm, adaptive control height, airspeed balance, is a dual-channel input, dual-channel output of advanced control algorithms. Currently widely used in Boeing airliner. Which does not need the same as the ordinary PID control algorithm by the automatic control of the aircraft by the hands of the aircraft to control the plane after the flight control the middle of the rudder, and the aircraft engine accidental parking, ground operations must be started to glide in order to ensure that the aircraft will not crash down.
3) Integrated 9 axis, accelerometer, angular velocity meter, magnetic sensor, dynamic and static pressure sensor, high precision UBLOX gps module, using extended Kalman filter algorithm, temperature drift compensation to ensure that the data source accurate.
4) the use of gps fusion imu, gnss integrated navigation, in the case of gps loss of lock, can be converted to AHRS inertial navigation, to ensure that the aircraft attitude security
5) support up to 8-channel servo and high and low output, high flexibility, each channel can be set arbitrarily set.
6) support automatic ejection takeoff mode, ground preparation, climb, flight, parachute, landing mode automatically switch according to the task, without human intervention
7) support timing, fixed-point control camera camera

Third,the results of aerial photography

 
 
 
 

 

Fourth, the use of forest system customers case

 
 
 
 
 

Fifth, the flight effect map

 
(Unmanned aerial vehicles for anti-drug) through the aircraft to shoot the photos found suspicious sites
 
 
 
 
According to the photo shoot recorded GPS point, directly to find the poppy cultivation
 
 
 
Conclusion: It can be seen that the application of UAVs focuses on the accurate grasp and timely understanding of the dynamic information of the major forest fires in remote areas where the ground patrol can not be taken into account, as a powerful complement to existing forestry monitoring methods, Unmanned aerial vehicles show that other means can not match the superiority, in the forestry fire monitoring, prevention, fighting, post-disaster assessment and anti-drug, etc. will be widely used.
