Overview of Drones
① Definition
Unmanned aerial vehicle (UAV) is surely an aerial vehicle that is operated by just a wireless remote control device or controlled by the program. It does not call for the pilot to drive inside cabin and the flight is automatically controlled by just a electronic device. So there isn't any need to install every pilot-related equipment on this, which effectively saves plus utilizes space to load other payloads to perform various tasks. The biggest difference between a drone along with a manned aircraft is in which drones cannot perform any task without getting a strict control system and equipment to become carried according to the actual mission.
② History
The world's first drone was given birth in 1917 made because of the British. It has been known for nearly a 100 years. However its application was with the 1950s. It was used to be a target drone in your early days. Later, it had been gradually used in your fields of aerial reconnaissance, digital camera countermeasures, and target hint. In the Vietnam War of the 1960s and the Middle East War on the 1970s, drones had important performances. During the Gulf Warfare and NATO air moves against Yugoslavia, drones were frequently utilized to perform military missions.
③ Military Application
After the Gulf Struggle, the role of drones while in the war was fully acknowledged. Many countries began to apply high technology to drones for making their technology develop immediately. The use of light materials and new styles has greatly increased the endurance from the drone. Advanced signal processing and communication technology improve the image transfer speed. Autopilot allows UAV in order to automatically change altitude and heading to the target. The ground operator could change the flight data as needed with the computer. In the war from the 1980s, drones were already qualified to attack targets on soil. Its importance in your military field is a lot more clearly presented to everything.
④ Classification
After nearly 100 years of development, you can find variety types of drones. If indexed by flight distance, there are short-range drones, medium-range drones as well as long-haul drones. If indexed by aircraft shape, there are usually micro drones, small drones, choice drones and large drones. If classified influenced by its military applications, you can find target drones, reconnaissance air carriers, jammers and attack aircraft. If classified depending about flight principle, there are generally fixed-wing drones, rotor-wing drones along with unmanned helicopters.

The ground control technique mainly sets the flight path of the drone through the wireless communication system, collects that flight parameters, receives and monitors the slide images collected by task sensors, and adjusts the airfare attitude and tasks as outlined by the parameters in real time.
Application of UAVRSS in Disaster Emergency Rescue
UAV aerial remote sensing system may be used in resource survey, geographical monitoring, disaster emergency rescue et cetera.
Flood disaster monitoring and evaluation
At present, the chief flood hazard monitoring method would be to analyze the flood situation belonging to the entire drainage basin with the hydrological data obtained from the hydrological survey site about the ground. But these scattered data points are difficult to make a comprehensive information world wide web. If the drone aerial remote sensing technique are used to capture the disaster situation in the air, the information obtained might be faster, more objective along with comprehensive than other regular ways. Its main programs are as follows:
(1) Using video harnessed by drones to analyze the current status, changes and traits of flood situation.
(2) Extract the flood range to the aerial film and assess the damage loss.
(3)Determine the water level and water depth in combination with topographic data
(4)Combine land use databases to discover different land submerged styles and areas.
Meteorological Complete distruction Monitoring
Disaster information and photograph data provided by UAVRSS work extremely well for loss assessment, process monitoring and accurately working out the disaster area. Simultaneously, UAVRSS can implement real-time dynamic monitoring with the intensity and distribution regarding rain, snow and ice disasters helping us to quickly study the final law of the devastation occurrence and development and supply timely and comprehensive information to make effective disaster relief measures.
Geological disaster inspection along with protection
The images associated with geological disaster areas presented by drones include details on geology, geomorphology, soil, hydrology, land use along with vegetation. This information constitutes the basis for any assessment of geological really bad problems. It is important to enhance the scientific, accuracy and effectiveness of geological disaster management and also disaster situation assessment within the region. Moreover, it can greatly enhance the efficiency and modernization a better standard of disaster reduction, resistance and prevention.
For major geological disasters just like landslides and debris runs, we can obtain disaster severity and distribution with the data provided by UAVs that will government allocate emergency reply resources and quickly have the debris flow environment info and monitor its dynamic changes to deliver basic data for correct forecasts.
Earthquake disaster recovery and assessment
The earthquake can be sudden and strong dangerous. So information’s timeliness is critical in the rescue. Once earthquake, it is essential to quickly grasp the quick comprehensive information and timely investigate losing so that disaster elimination decisions and implementation measures may be quickly and accurately developed to minimize losses. Even so, the disruption of communications and traffic and also the recurring aftershocks make it impossible for people to fast obtain 100 % information through conventional implies.
Drones can quickly get information of earthquake-stricken regions. Using the sensors to truly record the normal topography, artificial landscape and footprints of human activities on the ground, which can correctly, objectively and comprehensively mirror the comprehensive landscape from the earthquake-stricken area and supplies a scientific basis for seismic deterioration investigation and rapid review of losses. Moreover, it is possible to determine the location on the earthquake zone, the extent with the disaster area, the submitting of macroscopic seismic power, the damage of structures and structures, and the engineering facilities which might be in urgent need with repairs providing quick decision-making for any disaster, quick assessment involving earthquake losses, disaster elimination and disaster reduction.
Some great benefits of using drones in disaster rescue
1. Easy to sling and respond quickly
Small drones are only some kilograms and can be manipulated by remote control or laptop. An unassembled drone is often easily carried in an automobile or on a aircraft. Some drones require very easy take-off conditions, and they usually are ejected and taken off inside a car. For the VTOL drone, it will take off with a several square meters of toned land.
2. The live video information is transmitted to the command center in real time for the commander for making judgments and decisions.
That basic equipment normally placed by UAV is photographic camera and video transmission procedure. The digital camera is accountable for video shooting and in that case output it to transmitter onboard. The After encoding and compressing, transmitter deliver video data to recipient in command center.
THREE OR MORE. With communication relay function, fast recover local transmission on site
Air communication relay is definitely an important use of drones. As soon as natural disasters (such as earthquakes, floods, mudslides, tsunamis, and many others. ) occur, the original wired in addition to wireless communication systems within the ground are destroyed inside a certain area. At this time, information transmission becomes a large problem. The drone works extremely well as a convenient communication relay machine to create an invisible information "bridge" between the command center plus the scene, quickly forming when you need it local wireless communication network to solve the urgent need along with win valuable time to get disaster relief.
4. Track the introduction of the incident and support the command center that will implement uninterrupted command running
Because the drone is simple to use and can continuously track the development of the event, it may help the command center to grasp the event situation with time. In terms of checking incidents, drones have a plus over manned aircraft. Due to its small size, its speed is easy to control. Because involving its good maneuverability, the drone might be turned over quickly whenever a sharp turn is required. In addition, drones can fly at suprisingly low altitudes, while manned aircraft flying from the mountains are subject in order to flight height limitations.
