The use of light materials and new patterns has greatly increased the endurance in the drone. Advanced signal processing and communication technology enhance the image transfer speed. Autopilot allows UAV that will automatically change altitude and heading to the target. The ground operator may change the flight data as needed through the computer. In the war of the 1980s, drones were already capable of attack targets on ground. Its importance in the military field is a growing number of clearly presented to the globe.

    ④　Classification

    After nearly a hundred years of development, you can find variety types of drones. If listed in flight distance, there usually are short-range drones, medium-range drones in addition to long-haul drones. If classified by aircraft shape, there are generally micro drones, small drones, low to medium drones and large drones. If classified influenced by its military applications, there are actually target drones, reconnaissance planes, jammers and attack planes. If classified depending at flight principle, there are usually fixed-wing drones, rotor-wing drones as well as unmanned helicopters.

    UAVRSS(Unmanned Aviation Auto Remote Sensing System)

    The UAV remote sensing product mainly composed of unmanned aerial autos, flight control systems, steady pan-tilt, mission sensors, wireless communication systems, data processing and application analysis techniques, and ground control methods.

    The unmanned aerial vehicle: It is consist of an engine, a steering apparel, a flight control model, a wireless communication system, a GPS unit, a attitude measuring unit, and also a self-feedback stable pan-tilt.

Ground monitoring station video display units and regulates the airfare and mission status instantly.

    The stable pan-tilt immediately monitors the heading, pitch angle and flip angle with the aircraft and implements the task sensor to get parallel to the horizon and vertically shooting by way of a three-axis self-feedback control platform.

    The mission sensor could be equipped with digital camcorders, digital video cameras, infrared video cameras, hyperspectral sensors and other sensor devices according to remote sensing mission specifications.

    Wireless communication system becomes aware of point-to-point real-time data as well as hd video transmission via wireless COFDM technology.

    The data processing and application analysis system may automatically batch process training video and multi-spectral images in real time, quickly detect and recognize edges, and measure structural data to obtain rapid positioning, classification, feature parameter statistics, development problem prediction and thematic details extraction and mapping regarding monitoring targets.

    The ground control system mainly sets the flight path of the drone through the cellular communication system, collects the actual flight parameters, receives and monitors your data collected by task sensors, and adjusts the airline ticket attitude and tasks reported by the parameters in real time.


    Application of UAVRSS inside Disaster Emergency Rescue

    UAV aerial remote sensing system are available in resource survey, the environmental monitoring, disaster emergency rescue and so forth.

    Flood disaster monitoring along with evaluation

    At present, the main flood hazard monitoring method would be to analyze the flood situation on the entire drainage basin from the hydrological data obtained with the hydrological survey site on the ground. But these scattered info points are difficult to make a comprehensive information web. If the drone aerial remote sensing strategy is used to capture the disaster situation in the air, the information obtained might be faster, more objective as well as comprehensive than other normal ways. Its main applications are as follows:

    (1) Using video seized by drones to analyze the contemporary status, changes and traits of flood situation.
    (2) Extract the flood range for the aerial film and examine the damage loss.
    (3)Determine the water level and water depth in combination with topographic data
    (4)Combine land use databases to view different land submerged types and areas.

    Meteorological Devastation Monitoring

    Disaster information and picture data provided by UAVRSS can be utilized for loss assessment, practice monitoring and accurately working out the disaster area. While doing so, UAVRSS can implement real-time dynamic monitoring in the intensity and distribution with rain, snow and ice unfortunate occurances helping us to quickly study the law of the accident occurrence and development and still provide timely and comprehensive information to create effective disaster relief methods.

    Geological disaster inspection and protection

    The images of geological disaster areas furnished by drones include tips on geology, geomorphology, dirt, hydrology, land use and also vegetation. This information constitutes the basis for the assessment of geological disasters. It is important to boost the scientific, accuracy and effectiveness with geological disaster management in addition to disaster situation assessment in the region. Moreover, it can greatly enhance the efficiency and modernization level of disaster reduction, resistance in addition to prevention.

    For major geological disasters for example landslides and debris passes, we can obtain devastation severity and distribution throughout the data provided by UAVs to help government allocate emergency reaction resources and quickly obtain debris flow environment info and monitor its dynamic changes to produce basic data for accurate forecasts.

    Earthquake disaster test and assessment

    The earthquake is sudden and strong harmful. So information’s timeliness 's very important in the rescue. Immediately after earthquake, it is important to quickly grasp the beginning comprehensive information and timely investigate losing so that disaster comfort decisions and implementation measures may be quickly and accurately produced to minimize losses. Even so, the disruption of communications and traffic as well as recurring aftershocks make it impossible for people to fast obtain whole information through conventional suggests.

    Drones can quickly get hold of information of earthquake-stricken areas. Using the sensors to truly record the healthy topography, artificial landscape and traces of human activities for the ground, which can effectively, objectively and comprehensively reflect the comprehensive landscape in the earthquake-stricken area and supplies a scientific basis for seismic accidental injuries investigation and rapid test of losses. Moreover, it is possible to determine the location belonging to the earthquake zone, the extent from the disaster area, the syndication of macroscopic seismic depth, the damage of houses and structures, and the engineering facilities which can be in urgent need of repairs providing quick decision-making for any disaster, quick assessment regarding earthquake losses, disaster pain relief and disaster reduction.

    Some great benefits of using drones in catastrophe rescue

    1. Easy to transport and respond quickly

    Small drones are just a few kilograms and can be manipulated by handy remote control or laptop. An unassembled drone is usually easily carried in your car or on a aircraft. Some drones require very easy take-off conditions, and they might be ejected and taken off in the car. For the VTOL drone, it can take off with a couple of square meters of toned land.

    2. The live video information is transmitted towards the command center in real time for the commander to make judgments and decisions.

    Your basic equipment normally placed by UAV is photographic camera and video transmission program. The digital camera is accountable for video shooting and subsequently output it to transmitter onboard. The actual After encoding and compressing, transmitter deliver video data to receiver in command center.

    THREE OR MORE. With communication relay purpose, fast recover local conversation on site

    Air communication relay is definitely important use of drones. When natural disasters (such when earthquakes, floods, mudslides, tsunamis, and many others. ) occur, the original wired and wireless communication systems on the ground are destroyed in the certain area. At this time, information transmission becomes a big problem. The drone work extremely well as a convenient communication relay machine to develop an invisible information "bridge" in between the command center and the scene, quickly forming an emergency local wireless communication network to resolve the urgent need in addition to win valuable time intended for disaster relief.

    4. Track the development of the incident and assistance the command center for you to implement uninterrupted command canning

    Because the drone is convenient to use and can continuously track the introduction of the event, it may help the command center to discover the event situation with time. In terms of checking incidents, drones have a benefit over manned aircraft. Thanks to its small size, its speed is straightforward to control. Because associated with its good maneuverability, the drone may be turned over quickly whenever a sharp turn is wanted.
