The drone is referred to as the "UAV" and the English abbreviation is "UAV". UAVs first appeared in the 1920s. They have been in existence for hundreds of years, from military to civilian, to a group of consumer-class drones represented by Dajiang. The application field of drones is expanding like never before, and drones appear in commercial, agricultural, public utilities and so on. In addition to the well-known DJI brand, Parrot, 3DRoboTIcs, and Yihang are also launching powerful drones. What kind of mystery is hidden inside the drones of various brands? What is the configuration?
Let's take a look at the five latest consumer-grade UAV solutions!
1. Dajiang - Phantom 4
In the civilian quadcopter market, Dajiang is the king of no doubt. When various drone manufacturers are still chasing the Elf 3 in all aspects, DJI has launched the Elf Phantom4 without warning. The biggest feature of Phantom 4 is its "obstacle perception", "smart following" and "pointing". "Flight" three functions. It can identify surrounding objects, judge the flight environment, and achieve autonomous flight under certain conditions.
Basic parameters related to Phantom 4:
Weight (with battery and paddle) 1380 grams
Diagonal distance (without paddle) 350 mm
Maximum ascent speed 6 m/s (sport mode)
Maximum descent speed 4 m/s (sport mode)
Maximum horizontal flight speed 20 m/s (sport mode)
Maximum flight altitude of 6000 meters
Flight time 28 minutes
Satellite Positioning Module GPS / GLONASS Dual Mode
The Phantom4's pan/tilt has a controllable range of tilt from -90° to +30°, and a stable system: 3-axis (pitch, roll, yaw). For the camera, the image sensor is 1/2.3-inch CMOS with 12 million effective pixels. The remote control's operating frequency is 2.400-2.483GHz. Battery 6000 mAh Lithium rechargeable battery 2S. The Phantom4 camera can shoot 4K/30fps and 1080p/120fps video. The camera lens is specially optimized for aerial photography, and the lens with ultra-low distortion of 94° viewing angle and f/2.8 aperture is sharp and sharp. Using computer vision to achieve autonomous flight, the related chip is Movidius' Myriad 2 chip. The chip consumes very low power and provides floating-point performance at half-watt power consumption and is fabricated using a 20-nanometer process. The visual downsight positioning system consists of a binocular vision sensor and a set of ultrasonic sensors. Effective when the flying height is less than 10 meters, the visual positioning system can enhance the hovering accuracy and flight stability. The Phantom 4 is equipped with a dual compass module and a dual inertial measurement unit that takes data from two sets of sensors and compares them to detect data accuracy through advanced algorithms.
In the event of a power outage, the emergency exit light displaying the exit sign must remain lit for an emergency period of 90 minutes and must remain lit continuously in working condition. Specially designed plastic and acrylic materials are lightweight, ABS material is strong, insulating, and not conductive. The letters "EXIT" can be printed on the transparent acrylic sheet and can be customized in green or red. Easy to install, simple to operate, can be hung on the wall or hung from the ceiling. The Emergency Exit Sign lamp suitable for different commercial buildings or public places such as hospitals, schools, subways, train stations, etc.
