Sensors make pilotless, and speedometers are used to determine position and flight attitude. These small MEMS sensors play a key role in maintaining flight control. There are many ways to sense the motion attitude of the accelerometer, and one type of technology can sense the tiny motion of the micro integrated circuit. This kind of "diving board" movement changes the current movement in the structure, thus indicating the displacement change related to gravity.
The precise positioning of Surveying and mapping UAV is due to the application of the MEMS magnetic sensor used to detect the earth's magnetic field to the navigation system of aerial photography UAV, in order to improve the accuracy and speed of navigation and positioning.
How can the endurance of electric inspection UAV be effectively solved? Industrial surveying and mapping UAVs such as electric power patrol line, police reconnaissance, search and rescue have higher requirements for endurance. Some insiders say that airtime is a prerequisite for industrial surveying and mapping UAVs to solve all operational problems. Once the airtime problem is solved, the application scenario and use of Industrial Surveying and mapping UAVs will be greatly expanded. Way. So how to effectively solve the problem of the endurance of the electric patrol UAV?
In recent years, UAV has become more and more popular. Whether it is for work or entertainment, it is inevitable that there will be damage in the use process. The daily maintenance of UAV is the guarantee of UAV flight safety and use time. Battery Batteries are absolutely consumable in UAV. Six criteria should be followed in the process of use: "not long enough, not long enough to place, not enough power to save, not damaging the skin, not short circuit, not `catch cold'". When flying, try not to run out of battery power. When returning, at least 15% of battery power should be maintained and flying at a uniform speed. If the battery is not in use for a long time, please store it half-electrically. Do not store it at full voltage or empty voltage. Charger should set the type of charging battery and plug connection correctly. When using batteries, pay attention to whether the voltage and electricity drop too fast. Usually, when used twice a week, the batteries begin to age significantly for at least one year. Batteries should not be used when bulging occurs, because it does not guarantee long flight time. When you go out to work, you should pay attention to the "warmth" and "cooling" of batteries.
