Winter UAV Power Patrol script: the most complete strategies are here

as we all know, power patrol inspection is not only a deep mission, but also has certain risks. Whether it is hot summer or snow covered in winter, the "high-altitude figure" of manual power inspection operators is impressive. Nowadays, driven by market demand, UAV Power Patrol greatly reduces the workload of power employees

however, although the UAV is flexible, efficient and highly prepared, it can quickly reach remote areas that are difficult to reach by manpower for patrol inspection. It is a good helper for ice disaster relief. However, it is not easy to use UAV for power inspection. The difficulty is different in different terrain and different seasons, which also has a certain impact on the operation of the flying hand. Especially in the cold winter, UAV flight has also been challenged. Therefore, there are different ways to open the UAV in the ice and snow

if you follow this guide, the flight operation will be more perfect

the structure corresponding to the single arm type is the portal structure. Next, let's get the correct operation method when using it

making the battery "full of energy" in winter

it is an irresistible natural phenomenon to shorten the battery life in winter. Too low temperature will greatly reduce the efficiency and activity of the battery, thus affecting the normal operation of UAV. Low temperature weather often occurs in the north or high altitude areas. It is still cold in the south in winter. The aircraft is powered by lithium batteries. At this time, if the battery is placed outside for a long time, its discharge performance will be greatly reduced in the low temperature environment, and the battery capacity will be sharply reduced. If you still fly at normal temperature, there will be problems. It is found that the battery problem has troubled many inexperienced pilots, who have asked for help from senior pilots. (this figure is only a part, and does not specifically refer to the brand)

tips: in order to ensure the normal operation of the battery in intelligent flight, Liu Gao, the person in charge of Guangdong electric machinery patrol operation site, suggested the following five steps:

1. Before flight, the battery must be fully charged, take off with full power as far as possible, and ensure that the battery is in a high voltage state. If the low battery takes off, the initial voltage of the battery is low, and the temperature of the battery body is low, the voltage will be pulled down rapidly, which greatly increases the risk of insufficient voltage and is easy to cause power failure and explosion

2. Be sure to observe the battery temperature of the aircraft before flying. The battery is forbidden to be used when the temperature is below -10 ℃. When the battery temperature is between -10 ℃ and 5 ℃, it is necessary to keep hovering at low altitude for about 1 minute after takeoff, and preheat the battery. When the temperature is above 5 ℃ and the soft and anti-skid feel is moderate, the flight can be normal

3. Before takeoff, the battery needs to be insulated and stored in a warm environment to raise the battery temperature and ensure stable output current. To quickly install the battery during takeoff and perform the flight mission

4. In low temperature environment, the voltage will drop very quickly. At this time, it is necessary to shorten the flight time, set the low battery alarm voltage at 50%, and control the battery power at more than 30%

5. Fully warm up the aircraft before takeoff. Some cooling holes of the aircraft can also be temporarily sealed, which can also make the aircraft have a thermal insulation effect

outdoor operation magic weapon of "soul" flying hand

flying hand also faces severe challenges in extremely cold environment. Liu Gao told Yuchen that during winter operation, due to the cold weather, the hands of the flying hands are easily frozen stiff, so that the fingers are not flexible, unable to keep up with the response of each rudder in time, unable to operate smoothly, and easy to cause machine damage caused by improper operation. The weather will also lead to the decline of aircraft performance, and the electronic equipment of flight control may not work normally. At this time, the operation of the pilot will also be affected. And under the influence of low-pressure air flow, the instability of the aircraft flight state will make it difficult for the pilot to adjust the attitude in time. Li Bo, a veteran pilot, also sighed, "If the flying hand does not do a good job of thermal insulation, let alone operate the UAV safely, it will be difficult to guarantee his own health.

tips: Liu Gao summed up valuable experience to Yuchen:

1. The flying hand needs to be equipped with sufficient thermal and wind protection equipment to ensure that his hands and feet are flexible and his mind is clear;

2. When flying in icy or snow covered weather, due to the large light reflection effect, the flying hand is Eye damage is serious. Goggles can be equipped to solve this problem

3. In order to prevent aircraft performance degradation, the aircraft needs to be maintained regularly. Before takeoff, the aircraft must be preheated for enough time to ensure stable aircraft performance before takeoff

4. Always pay attention to the weather changes on site, know the weather conditions around the operation through a reliable weather forecast app, and the site should be equipped with anemometer. Blind operation is strictly prohibited when the wind speed is too high

inexplicably out of control remote controller

three senior pilots once said in the exchange that during the test flight in low temperature environment, inexplicably out of control occurred several times. After studying the flight data of the UAV, it was found that the problem was not the UAV itself, but the potentiometer of the remote controller. The so-called potentiometer refers to the device inside the remote control rocker to detect the displacement. It will expand and contract with the change of temperature, which may lead to poor contact and cause the aircraft out of control. Many pilots have encountered similar problems in the cold environment before. Most of them think that there is a problem with the UAV or PTZ, and rarely think that it is the fault of the remote control

tips: to operate the UAV under extremely cold conditions, it is necessary not only to keep the batteries and flying hands warm, but also to maintain the temperature of the remote control

it is found on the Internet that there are special gloves for flying hands, which can not only protect the hand temperature, but also ensure the temperature of the remote control. When using, you can put your hands and the remote control into a bag and observe it through plastic cloth, which can not only maintain the temperature of the remote control, but also prevent your hands from providing solutions to frostbite for a series of industrial markets related to personal hygiene, such as automobile, packaging, medical care, household appliances and construction

the machine itself is also an object that needs to be protected

a UAV user told Yuchen that when performing a mission in Xinjiang at about minus 15 degrees, the flat tail of the VTOL fixed wing UAV is a 3D print, which is spliced with glue, and will be caked under low temperature conditions. But no one noticed this detail that day. After the plane took off, I felt that there was something wrong with the flying posture and thought I was dazzled. After the plane returned, it was found that the flat tail was tilted by nearly 45 degrees. If it was not for the good redundancy design of the plane, it was possible to crash or lose it

delete the currently selected group of records tips:1. During the flight, it is very important to note that although the air humidity is easy to be ignored. The common snow and fog days in winter usually lead to the increase of air humidity. Water mist or snow may enter the body and cause corrosion and damage to internal parts. Therefore, it is necessary to dehumidify the aircraft after the flight. The treatment method is to wrap the napkin with good texture to absorb water, and observe it at all times to prevent the liquid from entering the aircraft

2. In the cold atmosphere, some parts, such as blades, will become more vulnerable. It is necessary to check the blade and shell more diligently for cracks. It is also possible to consider replacing them with solid carbon fiber blades

3. If there is ice on the flat tail, a hole can be punched through the tail, a willow can be placed, and then glue can be used to bond. Even if the tail is degummed, it will not shake
