Today we will return to the drone equipment itself, talk about common situations in safe use, and what you must know during daily maintenance, and help everyone start a drone flight journey. Safe use 1. Be "nice" to the propeller" The damage of the propeller will affect the flight stability of the UAV and affect the quality of the captured image. In normal use, there are not many opportunities for the UAV to fall to the ground and cause the blade to break, but the tree collision caused by visual error or improper manipulation occurs frequently. Therefore, it is necessary for the pilot or observer to observe the obstacles in the flight path as clearly as possible before takeoff. At the same time, daily also need to pay special attention to whether the blade cracks, gaps and other issues directly affect the flight stability. If the damage is serious, it is best to replace the new propeller directly. 2. Waterproof, moisture-proof and dust-proof In the industrial field, many times it is necessary to perform operations on sites with unique topography; many individual pilots like to photograph the sea. At this time, attention should be paid to avoid taking off from the sandy gravel ground as far as possible to prevent sand and dust from entering the motor, and to remove dust and clean it in time after use. When working, the motor is magnetic, and fine metal particles contained in dust and fine sand may be adsorbed into the motor, which may cause the motor to stop. If particles accidentally enter the motor, you can try to use a vacuum cleaner, but if the motor still does not run smoothly, you may have to disassemble the motor or repair it. 3. Prevent the influence of magnetic field It is recommended to calibrate the IMU and compass every time you go to a new place, because the turbulence of long-distance transportation has an impact on the IMU, and the different magnetic field environment in each place also has an impact on the compass. 4. When working in the field, the battery must be placed in a cool place to avoid direct sunlight. 5. Just finished the job, do not directly take the battery to charge, place for a period of time until the battery cooling stable before charging. 6. Grasp the operation time of the unmanned aerial vehicle, and the minimum voltage of each battery shall not be lower than 3.6v during the operation. 7. Before using the UAV in cold areas, the temperature of the battery should be preheated to about 25 degrees before flying (warm baby and hot water bag can be used for preheating through clothes); When flying at low temperature, the efficiency of the battery will be greatly reduced, and the probability of battery problems will be much higher than that at normal temperature. It is recommended to set the low battery alarm value to 50%, shorten the flight time and perform multiple flights to complete image acquisition. 8. When using drones in hot areas, especially when the light is strong, sun exposure and heat generated by their own work may cause the battery temperature to reach 65 ° or more. High temperature work will drastically shorten the battery life, accompanied by explosion, fire, smoke and other risks. It is recommended that the pilot monitor the battery temperature on the ground in real time. Once the danger threshold is exceeded, the drone should be landed as soon as possible to avoid danger. It is suggested to reduce the continuous operation time of UAV in high temperature environment. Maintenance after use 1. Clean up the water vapor on the unmanned aerial vehicle in time. If the unmanned aerial vehicle is affected with moisture or water during use, the power shall be cut off to dry the unmanned aerial vehicle after use, and then put it into a moisture-proof box to absorb moisture, and then use it after the moisture is removed. 2. If the drone has a problem of unexplained roll or unable to land smoothly when hovering, there may be a problem with the motor. You can try to re-calibrate the plane before taking off. If this problem still occurs, you need to send it to the factory for overhaul in time to avoid the loss of control or crash caused by the motor stopping. 3. Found that the metal sheet at the connection of the aircraft battery has dirt must be cleaned in time. 4. Regularly observe the status of UAV propeller blades and understand the status of equipment. 5. After the cumulative flight time of the aircraft exceeds 50-100 hours, it is recommended to observe the color of the metal wire in the motor. If problems such as discoloration are found, it is recommended to replace the motor so as not to cause flight safety problems. Battery maintenance 1. When using the battery, try to avoid overcharging or overdischarging. Try not to run out of battery power when flying, keep at least 15% of the power when returning home, and fly at a constant speed. You can pay attention to whether the voltage and power drop too fast. 2. Aerial photography operations, making digital ground models, should also pay attention to the impact of temperature on the battery. When used in low temperature areas, the battery should do a good job of "keeping warm" and "warming up" to reduce the rapid rise of voltage. 3. During daily storage, the battery should be kept at about 40-65%, and the battery should be discharged to 5% on the plane. 4. If the plan is not used for a long time, the battery should not be fully charged; if it is not used for two months, it should be fully charged once before use. 5. If the original charger of the model you purchased can charge the battery and the remote control at the same time, it is best not to charge at the same time for safety reasons. 6. For unfamiliar drones, check whether the battery can be used: observe whether there is a bulge on the appearance. A battery with a bulge can definitely not be used. Some special batteries for drones are installed in a protective shell to observe whether the battery is loose after installation. If the installation is not smooth, it is likely that the battery expansion will be squeezed out of the protective shell. Similarly, in the process of battery installation of different brands of unmanned aerial vehicles, it is necessary to consider whether the battery is deformed and cannot be used. 7. Charging precautions Not only drones, from the current technical point of view, charging is still a high incidence of battery accidents. We often learn from the news that battery cars and electric vehicles catch fire during the charging process. Therefore, the drone battery must also be guarded during the charging process. If you feel abnormalities such as sound or severe heat, disconnect the charging as soon as possible. At the same time, we should also pay attention to the battery charging progress. Excessive charging will affect the battery life, bulge, and cause explosion and fire. When used in the field, if the electric quantity is below 10%, it is over-discharge, which is very harmful to the battery life. If the operation relationship causes the battery to be over-discharged, the mobile power supply can be used for temporary remedy. In addition, it is suggested that the UAV manager should properly keep the original charger and charging line, and it is better to use the matching charging equipment for each charging. At the same time, do not charge the battery in a high temperature environment. Safe storage 1. Keep it clean and dry: As a kind of precision electronic equipment, the UAV needs to be kept dry and clean. Although the UAV is not damaged by water, if it is not treated in time after being exposed to water or damp, it will cause damage to electronic components, causing the UAV to malfunction and reducing the service life of the UAV. Therefore, the experience recommends that the pilot place a dry bag inside the box of the drone and replace it every one to two months. 2. The UAV plug should be connected with a protective cover to avoid short circuit. 3. In the process of storage and carrying, handle with care, do not hit, collision, be careful of sharp objects. 4. Draw key points: The propeller should be removed and preserved. Don't believe in unmanned aerial vehicle bags that can be stored without removing the propeller. This is the basic thing that novice users need to know when using unmanned aerial vehicles. After taking oblique photos, they can use Easy Model App to make the captured scenes into models. Without a computer, the whole mobile phone a key operation, 5-20 minutes to generate holographic color three-dimensional model. Select more than 50 images taken by unmanned aerial vehicles from the matching App of unmanned aerial vehicles and download them to the mobile phone. Then switch to Easy Mode App and select the scene modeling in [Custom Mode]. The system will automatically model after uploading the picture.
