How is the application of fixed UAV systems in China s civilian market?

Hello, happy to answer your questions.

The requirements for UAVs in the civilian field are usually below 100 kilometers per hour, flight altitude below 3000 meters, and 4000 5000 meters for some special applications. Due to the economy, safety and ease of operation of UAVs, there is a strong demand for UAVs in many civilian fields, and small UAVs can be widely used in disaster prevention and mitigation, search and rescue, nuclear radiation detection, traffic supervision, resource exploration, land and resources monitoring, border patrol, forest fire prevention, meteorological detection, crop yield estimation, pipeline inspection and other fields. Due to the aviation characteristics of small UAVs and the characteristics of large-scale inspections, they have special advantages in real-time monitoring and evaluation of natural disasters such as floods, droughts, **, and forest fires.

The application of civil UAVs in the field of aerial survey can also be used as a supplement to satellite remote sensing means. Satellite images have become the main data source for small- and medium-scale remote sensing monitoring and mapping, and even an important data source for the mapping and updating of 1:10,000 topographic maps and thematic maps.

However, due to the constraints of satellite space cycle, climate and supply channels, the coverage, timeliness and resolution of high-resolution satellite data ordered by users are greatly affected. In terms of UAV aerial photography, due to its advantages of strong maneuverability and high resolution, it can be used as a supplement to satellite remote sensing means to form an all-weather, all-weather, full-coverage three-dimensional monitoring system that combines high, medium and low platforms, and complements coarse, medium and fine resolutions. At present, many private enterprises have basic application capabilities in small UAV aerial survey, for example, Kunming Jinying UAV specializes in the design, production, sales, and aerial survey and aerial photography services of aerial survey UAV equipment, and is China's top technology aerial survey UAV design, manufacturing and aerial flight service provider.

One of the key problems faced by UAVs in expanding the application of civilian fields is to engage in "affordable equipment" and "equipment that can be driven", which can be used at low cost, so the body should reduce costs, and the flight control should also reduce costs; It can be driven, that is, it is easy to operate and easy to use, without too long a period of learning and training, and the autonomous performance of the UAV should be high, and the human factor should be minimized. Kunming Jinying UAV has low cost, strong technology, short construction period and high precision, and is leading in the industry. With the investment of state-owned capital and private capital, the basic technology of the UAV industry has gradually matured, the application field of UAVs has expanded from a single military field to the civilian field, and UAV manufacturers have gradually transformed from state-owned enterprises to private enterprises.

The continuous maturity of flight control and engine technology makes the overall technology gradually mature, and then promotes the maturity of market demand, and eventually will make the entire industry tend to mature. Therefore, the UAV industry will usher in a mature era.

Satisfaction.

It's not just these aspects. It also includes urban planning, environmental monitoring, power (telecommunications, television) line inspections, pesticide spraying, communication relays, etc., and will be used more and more extensively.

Summary. A drone is an unmanned aerial vehicle that is controlled by a radio-controlled device or its own program control device, which can achieve autonomous flight.

The UAV system refers to the control of the operation of the UAV, the UAV to complete the task, in addition to the need for the aircraft and the task equipment it carries, also need to have ground control equipment, data communication equipment, maintenance equipment, as well as command and control and necessary operation, maintenance personnel, etc., larger UAVs also need special launch devices. Therefore, UAVs in the full sense should be called UAV systems.

The difference between a drone and an unmanned aerial system.

Hello, I'm glad to serve you, your question Li Jingbei I have received which destroy, see will reply in time. After the question, because there are too many people asking for it, we will reply in turn, so please be patient and wait for the manuscript

A drone is an unmanned aerial vehicle that is controlled by a radio-controlled device or its own program control device, which can achieve autonomous flight. The UAV system refers to the control of the operation of the UAV, the UAV to complete the task, in addition to the need for the aircraft and the task equipment it carries, but also need to have ground control equipment, data communication equipment and equipment, maintenance equipment, as well as command and control and necessary operation, maintenance personnel, etc., larger UAVs also need special launch devices. Therefore, UAVs in the full sense should be called UAV systems.

Summary. Merit.

Avoid sacrificing flight crew, because there is no need for flight personnel on the aircraft, so the safety of human life is guaranteed as much as possible.

The UAV is relatively small in size, and is not limited by the physiological conditions of the pilot when designed, so it can have a great work intensity, and does not require a personnel survival support system and an emergency rescue system, which greatly reduces the weight of the aircraft.

Low manufacturing cost and life cycle cost, no expensive training and maintenance costs, long service life of the body, easy to overhaul and maintain.

The technical advantage of UAVs is that they can take off and land at fixed points, and the conditions of the take-off and landing sites are not high, and they can be remotely controlled by radio or through the on-board computer.

The diversity of equipment and its adaptability are good.

2.Limitations of UAVsCompared to manned aircraft, UAVs have the following limitations. (1) There is no pilot and crew on the drone, and the dependence on navigation systems and communication systems is higher.

2) UAVs relax redundancy and reliability indicators, reducing flight safety. In the event of a mechanical failure or electronic obstruction, drones and onboard equipment can cause fatal injuries. (3) The endurance of drones is relatively short, especially electric drones.

4) The communication frequency and ground obstacles of UAV remote control, ground station, image transmission, data transmission radio and other equipment limit the communication transmission distance of UAV system and limit the flight range of UAV. (5) The volume, weight and power of the UAV determine the limited wind and rain resistance of the UAV.

What is the take-off problem caused by improper control of the drone.

Ask about custom messages].

The drone has two modes of operation:

1. Operate according to the pre-set procedures. Usually the mission with a relatively fixed flight trajectory, such as reconnaissance of a fixed area and delivery of a fixed location, will adopt this mode. The disadvantage is that it is too rigid and lacks the ability to respond flexibly.

2. Human-style remote control mode. This approach is relatively flexible, but there is still a time delay.

In general, there are no random people on the drone, and there is a lack of immediate response to emergencies and unforeseen events.

So at present, UAVs cannot completely replace manned aircraft.

The UAV flight system mainly uses the following electronic equipment. electronic equipment, radio remote control equipment, radio telemetry equipment, radiopositioning equipment, information transmission equipment, relay equipment, etc. (this part is often called data link); Task equipment.

Flight control is involved in those functions of air-land amphibious UAVs.

I don't quite understand what you mean, can you explain it?

It is the flight control that participates in those functions of the amphibious drone.

The flight controller generally includes three parts: sensors, on-board computers and service search and service actuation equipment, and its main function is to automatically maintain the normal flight attitude of the aircraft, including geomagnetic induction, ultrasonic sensor, optical flow sensor, control circuit, accelerometer, barometric pressure sensor, GPS module and gyroscope.

To be exact. To be precise, the main function is to control the power of the aircraft.
