UAV as a training plan for college students' innovation and entrepreneurship. . I hope to give a feasible scheme. thank you

As one of the two branches of spatial information technology system, aerial photogrammetry technology has an important application in surveying and mapping industry. The traditional aerial survey equipment is bulky, has a large carrier, is not flexible enough to use, and requires high personnel, so it has not been widely promoted. With the progress of science and technology, drones have gradually spread from the military field to the civilian industry. Compared with traditional aerial survey aircraft, Jinying 1 aerial survey gasoline aerial survey UAV has the advantages of low cost, safety of flight controllers, low flight cost, flexibility, multiple functions, rapid task deployment and over-the-horizon automatic driving, so it is of great practical value to develop aerial survey solutions based on Jinying 1 aerial survey gasoline aerial survey UAV.

I. Main components

The aerial survey solution of Jinying 1 gasoline aerial survey UAV mainly includes four parts: flight system, data link, ground control and data processing.

1, flight system

Flight system is the most important part of the whole solution, and its overall cost determines the cost of UAV aerial survey solution. The principle of this solution is low cost and easy maintenance, so all accessories are selected from mature products in the market. The flight system mainly includes aircraft, power, control system, energy supply and camera system.

A. Carrier-based aircraft: Choosing a fixed-wing aircraft as a carrier-based aircraft has the advantages of high stability, strong wind resistance and strong site adaptability.

B. Power: The power of the general airplane model is oil and electricity, which has heavy oil and electricity load, long range and strong endurance. Finally, oil power is selected as the power source of the aircraft.

C control system: the control system includes two parts: manual remote control and automatic driving. Manual remote control is mainly responsible for human intervention in take-off and landing to avoid the unknown influence of automatic take-off and landing. It is very flexible in the selection of aerial survey sites, and it is more efficient than the self-propelled UAV. The autopilot system is mainly responsible for autonomous flight control from the landing point to the investigation area according to the preset waypoints in the investigation area. The automatic control system includes corresponding auxiliary sensors such as airspeed indicator and GPS.

2. Data transmitter

The data link includes the carrier part and the ground station part. Its main purpose is to transmit the flight attitude back to the ground station in real time, and transmit the preset waypoint tasks, flight instructions and debugging data from the ground station to the flight control system of the carrier in real time, which is the guarantee for the carrier to perform the measurement tasks normally.

3. Ground controlled

The ground control system adopts the software matched with the aircraft automatic control system, which is mainly responsible for the setting of measurement tasks, the debugging of flight control parameters and the preparation of parameters before takeoff.

4. Data processing

The format of outfield flight data can be freely converted by software to adapt to different processing schemes. Post-processing can choose different software and processing schemes according to different precision and product differences. According to the customer's demand for surveying and mapping products, the appropriate treatment scheme can be selected, which has obvious advantages in controlling costs.

Second, the performance and aerial survey application of Jinying 1 gasoline aerial survey aerial survey UAV.

2. Successful cases

Jinying 1 gasoline aerial survey aerial survey drone went to Africa and other foreign aerial surveys with harsh natural conditions, and came to Songming County and Lijiang Grand Canyon all the way. With rich aerial photography experience, technology and careful preparation, we also successfully completed the aerial survey task! After several years of flight challenges, such as high altitude limit, bad take-off and landing conditions, complex airflow environment, large-scale operation in plains, extremely high temperature environment in Africa, and high precision requirements in Europe, it has become a very stable and mature aerial survey aerial drone.
