Anti-electromagnetic method for mooring unmanned aerial vehicle and anti-electromagnetic structure of mooring unmanned aerial vehicle

Abstract

The invention discloses an anti-electromagnetic method for a mooring unmanned aerial vehicle. The method comprises steps as follows: high-frequency burr waves in high-voltage direct-current electricity are separated and lead to the ground to be dissipated through a feed-through capacitor; a positive wire and a negative wire of a transmission cable are wound at two ends of a prearranged magnetic ring, and wave crests in the high-voltage direct-current electricity are reduced under the reverse-phase function of the magnetic ring; the positive wire and the negative wire of the transmission cable are intertwined, so that the high-voltage direct-current electricity can counteract electromagnetic waves sent from the positive wire and the negative wire in the transmission process of the transmission cable; the positive wire and the negative wire are covered with first metal covering layers which convert the electromagnetic waves in the high-voltage direct-current electricity into relatively weak electricity to be transmitted to the ground to be dissipated; a cable module is covered with a heat-dissipating covering layer which converts the electromagnetic waves in the high-voltage direct-current electricity into heat to be dissipated in air; a motor is covered with a second metal covering layer which converts the electromagnetic waves in the high-voltage direct-current electricity into relatively weak electricity, so that the relatively weak electricity can be lead into the ground to be dissipated.

Description

technical field [0001] The invention relates to an anti-electromagnetic method for a tethered unmanned aerial vehicle and an anti-electromagnetic structure for a tethered unmanned aerial vehicle. Background technique [0002] Tethered UAVs have been widely used in many fields. When tethered UAVs are working, they need to be connected to UAVs in real time through transmission cables to supply power to UAVs, so as to drive UAVs to achieve various tasks in the air. Operation, the generator in the ground workstation generally provides 220V or 380V AC power, but before the power is transmitted to the drone through the transmission cable, the AC power generated by the generator needs to be converted into DC power through a switching power supply, and the 220V or 380V The voltage is transformed into a high voltage of 800~1000V, and then transmitted to the motor of the drone through the transmission cable, so as to drive the drone to fly or achieve other operations through the mot...

[0002] Tethered UAVs have been widely used in many fields. When tethered UAVs are working, they need to be connected to UAVs in real time through transmission cables to supply power to UAVs, so as to drive UAVs to achieve various tasks in the air. Operation, the generator in the ground workstation generally provides 220V or 380V AC power, but before the power is transmitted to the drone through the transmission cable, the AC power generated by the generator needs to be converted into DC power through a switching power supply, and the 220V or 380V The voltage is transformed into a high voltage of 800~1000V, and then transmitted to the motor of the drone through the transmission cable, so as to drive the drone to fly or achieve other operations through the motor; however, it can be known from the principle of electromagnetics that due to the large voltage The amplitude increases, so a strong electromagnetic field will be generated in the process of power transmission. The electromagnetic waves in this electromagnetic field will greatly affect the UAV flying in the sky to receive the flight control signal from the ground workstation, thus causing unmanned The control of the drone is not sensitive, and it cannot complete the scheduled tasks. Its safety performance will also cause certain hidden dangers, which affects the work efficiency of the tethered drone. Therefore, it is necessary to solve the problems caused by electromagnetic field interference to improve the receiving sensitivity of the flight control signal. , to ensure that the tethered UAV can perform tasks normally
