The principle of drone technology and the ultrasonic ranging technology

The principle of drone technology and ultrasonic ranging transducer demonstrates the loss feasibility of measuring the obstacles in the electrical circuit corridor; the third chapter mainly introduces the ultrasonic ranging transducer system equipment, including selection of UAV equipment parameters and its PTZ transmission acquisition, UAV flight control system has ultrasonic component control unit and data acquisition hardware; Introduction of ultrasonic ranging transducer has main program flow chart, ultrasonic back-transmission and image returns superimposition implementation.The design of the sequence is the fifth chapter mainly introduces the practical application of the UAV ranging technology, mainly including large-area tree barriers.Ultrasonic distance sensor are practical applications, and drone ranging should be carried out in helicopters, drones, and manual cooperative inspections to discuss its broad practical prospects. Summarized the main research results of this paper and analyzed.Deepen the theoretical research and unsolved technical problems in the application of the UAV ranging technology,

Unmanned aerial vehicle (UAV), which is a radio remote control device or itself. An unmanned aerial vehicle operated by a program control device. Modern unmanned aircraft is a complex set of aviation and electricity.it has the integrated systems such as sub-power, reconnaissance, geographic information, and image recognition. Due to altitude and long distance ultrasonic distance measuring transducer.The ability to leave and work quickly in the aspects of surveying, aerial photography, sports, military, reconnaissance and disaster prevention.due to the development of drone control technology, which can carry out telemetry data link control, geographical matching control system and GPS satellite potential control, control operation process is simple and reliable, stable, high economic performance, there is no affected by the climate, long battery life, fast speed and operating efficiency is more than 10 times that of manpower.At present, the technical development of drones is divided into two categories: fixed-wing UAVs and rotary-wing UAVs high performance and technical specifications

1, flight control can achieve manual control mode and self-driving mode. Flight control system takes autonomous landing, and automatically executes the navigation and mission commands loaded before take-off along the route main flight

2, the fuselage structure which the main components of the ultrasonic distance sensor circuit are concentrated in the center, the power system is symmetrically distributed around, and It can be folded and stored. Generally it is used for carbon fiber or honeycomb composite material, it has high strength, light weight, counterweight.The components are well protected and can withstand high frequency, high-intensity operation flight. it is multi-rotor drone,single rotor, quadrotor, multi-rotor. for ultrasonic or subsonic flight speed, fixed wing.Man-machines come in a variety of layouts. For subsonic aircraft, large aspect ratios and small sweeps are generally used.Angle (350 or so), with a supercritical airfoil wing to obtain a higher lift resistance under high cruising conditions ratio. For subsonic aircraft,which usually straights out without sharpening, the aspect ratio of high accuracy ultrasonic transducer sensor is above 6, normal layout.it has single rotor, quadrotor, multi-rotor, for ultrasonic or subsonic flight speed,which fixed to wing come in a variety of layouts. For subsonic aircraft, it is large aspect ratio , small sweep angle with a supercritical airfoil wing to obtain a higher lift resistance under high cruising conditions ratio. For subsonic small aircraft,which usually straights wing without sharpening, the aspect ratio is above 6 layout.
