Demand Analysis
Currently, drones are more and more widely used in the field of power transmission lines, and drone crashes happen from time to time. 1kg drone falling at 30 meters height and hitting a person's head will cause irreversible injuries and deaths; however, light drones are limited to a height of 120 meters, micro drones are limited to a height of 50 meters, and the general height of buildings and public facilities is 25 meters to 40 meters, with power lines, branches, high-altitude birds, electromagnetic interference, signal loss, and excessively low power, etc. There are too many unknown factors affecting the safety of flight. There are too many unknown factors affecting flight safety. To summarize, UAV crash damage seriously affects the efficiency of daily work, while causing unnecessary economic property loss, personal injury accidents.
Working Principle
In view of the current problems , and the daily work of the combination of the development of a drone anti-crash buffer device, this device is suitable for DJI Elf 4, Royal 2 drone and other models. The device can be set up parameters have angle and speed protection, in the drone before takeoff will be mounted on the back of the drone, when a serious collision occurs, the side flip flip angle reaches 90 degrees, the air stops, the free fall speed reaches the set value when the trigger buffer airbag device action, and immediately open the anti-crash buffer device, quickly slow down the faulty drone's falling speed, to avoid the drone directly hit the ground and cause damage, as well as to avoid directly hitting the ground and damage. It can also prevent the UAV from directly hitting the ground and injuring the personnel or other equipments on the ground.
Functional features
1、Large umbrella cloth area: it can be adapted to heavier DJI Elf series drones, and the average descending speed of the test is 5.5m/s (Elf 4), and it doesn't affect the upper RTK module and the lower gimbal.
2, replaceable umbrella cabin: more convenient to reuse, a variety of safety performance options, the use of replaceable umbrella cabin design, the umbrella cabin contains the power unit and umbrella, save the aircraft quickly replace the umbrella cabin, at the same time, divided into the standard version and Plus version of the umbrella cabin, the two common, in order to adapt to more models.
3、Convenient replacement: independent parachute bag, eliminating the trouble of opening and reassembling the parachute, convenient and worry-free.
4、APS scoring algorithm: industry-level UAV parachute algorithm transplantation, six-direction attitude sensing, millisecond response speed.
5、Dual-core scoring: Barometer and attitude sensor two-way scoring, detecting the real-time condition of the drone.
6、Independent firmware: DFU firmware switching, manually select the matching model algorithm, more secure.
7、Enjoy a safe and worry-free flight with the integration of three major functions: industrial-grade memory (black box), high-precision barometer, and omnidirectional attitude sensor for flight safety.
8, omni-directional attitude and barometer data collection and processing in real time, milliseconds in the discernment of the drone flight status, IMU and barometer summary scoring, but the perception of the drone is in a dangerous situation, 0.5 seconds of instantaneous response, you can send out the umbrella command, so that you fried chicken not panic, from the landing.
9, long battery life, more powerful: 150 mAh battery, to give you a smooth experience, charging once to meet the drone 30 minutes × 6 flight range, so that you have fun. Battery power can be viewed instantly, power report warning function.
10, sound warning / prompt: new buzzer, command prompts, the use of more easy to get started, after the opening of the umbrella continued to chirp to hear the sound defense.
11, lightly loaded, extraordinary hand
12, light weight, slight impact on the duration of the drone, so that you enjoy playing, because it is always there for you to escort.
