[0036] With the widespread use of electronic devices, the impact of electromagnetic pulse (EMP) interference on electronic devices has attracted more and more attention. Among them, drones are a typical example. Drones have been widely used in many fields such as military, agriculture, logistics, photography, etc. When flying, they may be interfered by electromagnetic pulses caused by natural phenomena or human factors, which may cause drones to malfunction or be damaged.

[0037] In the known technologies, drones usually use simple shielding or filtering measures to reduce electromagnetic pulse interference, but these measures are often not effective in dealing with strong electromagnetic pulse interference. For example, although traditional shielding methods can reduce electromagnetic interference to a certain extent, when facing high-intensity electromagnetic pulses, the shielding effect is limited and cannot completely protect the flight control module and other key circuit modules of the drone.

[0038] In order to solve the above problems, the known technology generally needs to set up complex anti-interference devices at a relatively high cost, which is not suitable for electronic devices such as drones that have high requirements for lightweight, and has the defect of high cost.

[0039] The present application provides an anti-interference device for a drone to solve the above-mentioned problems. Among them, the anti-interference device of the present application includes a nonlinear zinc oxide resistor, an electrode and a plurality of groups of conductors, wherein each group of conductors includes a positive conductor and a negative conductor. Specifically, the positive conductor and the negative conductor are respectively connected in series to the positive and negative electrodes of the electrode to form a closed loop. The nonlinear zinc oxide resistor is arranged between the positive and negative electrodes of the electrode, so that when the drone anti-interference device is interfered by an electromagnetic pulse, the nonlinear zinc oxide resistor can quickly change from a high impedance state to a low impedance state to absorb the energy brought by the electromagnetic pulse, and can release the excess energy into a plurality of closed loops, thereby effectively protecting the drone. The drone anti-interference device of the present application has the characteristics of low cost, simple and light structure.

[0040] It is understandable that the anti-interference device for drones of the present application can also be applied to any electronic device that needs to resist electromagnetic pulse interference and has high requirements for lightness, which is not limited in this embodiment. Figure 1 A schematic diagram of an application scenario of a drone anti-interference device provided in an embodiment of the present application, such as Figure 1 As shown, the UAV anti-interference device 2 can be set on the outer shell of the UAV body 1. During the flight of the UAV, it may be interfered by electromagnetic pulses caused by natural factors such as solar storms. By setting the UAV anti-interference device 2 of the present application on the outer shell where the flight control module, sensitive devices, etc. of the UAV body 1 are located, the electromagnetic pulse interference can be suppressed, thereby effectively protecting the UAV flight control module, etc., and ensuring the safe flight of the UAV.

[0041] It is understandable that during the flight of a drone, electromagnetic pulse interference may be caused by human factors, such as the presence of other high-power electronic devices during the flight. Through a drone anti-interference device of the present application, the electromagnetic pulse interference can be effectively suppressed.

[0042] Specifically, when the drone is subjected to electromagnetic pulse interference due to natural factors such as lightning, solar storms or other human factors, the nonlinear zinc oxide resistor of the anti-interference device quickly reduces its resistance to absorb the energy generated by the electromagnetic pulse and releases the excess energy into a closed loop composed of positive conductors, negative conductors, etc., thereby preventing the electromagnetic pulse from damaging the flight control module, sensitive devices, etc. inside the drone and ensuring the safe flight of the drone.

[0043] Understandably, Figure 1The area within the middle dotted line is the location of the UAV anti-interference device 2.

[0044] In the following, some embodiments of the present application are described in detail in conjunction with the accompanying drawings. In the case where the embodiments do not conflict with each other, the following embodiments and features in the embodiments can be combined with each other.

[0045] Figure 2 A schematic diagram of the structure of an anti-interference device for a drone provided in an embodiment of the present application Figure 1 ,like Figure 2 As shown, in this embodiment, the UAV anti-interference device 2 is used on the UAV body 1. Specifically, the UAV anti-interference device 2 includes an electrode 23, a plurality of groups of conductors, and a nonlinear zinc oxide resistor 24.

[0046] The electrode 23 has a positive electrode and a negative electrode. In this embodiment, each group of conductors includes a positive conductor 21 and a negative conductor 22, and in the plurality of groups of conductors, the positive conductors 21 and the negative conductors 22 are arranged at intervals.

[0047] In this embodiment, the positive conductor 21 and the negative conductor 22 are connected in series to the positive and negative electrodes of the electrode 23 to form a closed loop. Specifically, the positive conductor 21 is connected to the positive electrode of the electrode 23, and the negative conductor 22 is connected to the negative electrode of the electrode 23.

[0048] Based on the above arrangement, multiple groups of conductors are connected in parallel to the positive and negative electrodes of the electrode 23, thereby forming multiple closed loops.

[0049] It is understandable that in practical applications, the electrode 23 may be an electrode sheet or an electrode block, etc., and the material may be copper, aluminum, etc. The conductor may specifically be a metal wire, a metal foil, a conductive coating, etc., which is not limited in this embodiment, as long as the anti-interference device of a drone of the present application can achieve anti-interference.

[0050] In this embodiment, the electrode 23 is specifically an electrode sheet, and the conductor is specifically an electric wire, which is made of a flexible conductive material. Based on this setting, when the drone anti-interference device 2 is installed on an electronic device, the shape of the conductor can be changed at will, so that various sensor probe holes and installation ports reserved for the drone can be flexibly bypassed, thereby enabling the drone anti-interference device 2 of the present application to adapt to the structure of the drone.

[0051] like Figure 1 As shown, in this embodiment, the nonlinear zinc oxide resistor 24 is arranged between the positive electrode and the negative electrode of the electrode 23. Specifically, the nonlinear zinc oxide resistor 24 is connected in series between the positive electrode and the negative electrode of the electrode 23, so that the electrode 23, the nonlinear zinc oxide resistor 24, the positive electrode conductor 21 and the negative electrode conductor 22 form a closed loop together.

[0052] When there is no electromagnetic pulse interference, the nonlinear zinc oxide resistor 24 is in a high impedance state and is almost non-conductive, so that no significant current flows in the closed loop. When subjected to electromagnetic pulse interference, when the voltage exceeds the threshold of the nonlinear zinc oxide resistor 24, the nonlinear zinc oxide resistor 24 quickly changes to a low impedance state, absorbs electromagnetic pulse energy, and releases excess electromagnetic pulse energy into the closed loop.

[0053] It can be understood that the nonlinear zinc oxide resistor 24 has higher performance than ordinary varistors, which can enable the drone anti-interference device 2 to have the advantages of high energy absorption capacity, fast response time, nonlinear resistance characteristics, wide voltage range, multiple uses and ease of use.

[0054] The anti-interference device 2 for drones provided in this embodiment forms multiple closed loops by setting a nonlinear zinc oxide resistor 24, an electrode sheet, and multiple groups of conductors, so that when electromagnetic pulse interference exists, the nonlinear zinc oxide resistor 24 can quickly reduce its resistance to absorb the energy generated by the electromagnetic pulse interference, and release the excess energy into the closed loop, thereby effectively suppressing the electromagnetic pulse and effectively protecting the electronic equipment to ensure the safe use of the electronic equipment. In addition, in this embodiment, the positive conductor 21 and the negative conductor 22 are arranged at intervals, which can effectively reduce the electromagnetic coupling between the conductors, thereby reducing electromagnetic interference.

[0055] It is understandable that, in this embodiment, when the drone is provided with the drone anti-interference device 2, an insulating material should be provided between the drone housing and the drone anti-interference device 2 to achieve electrical isolation between the drone and the drone anti-interference device 2. Specifically, the insulating material can be provided on the drone housing, and the drone anti-interference device 2 is provided on the side of the insulating material facing away from the drone. In practical applications, if the housing of the drone body 1 itself has insulating properties, the drone anti-interference device 2 can be directly provided on the drone housing.

[0056] It is understandable that, in practical applications, the number of positive conductors 21 and negative conductors 22 can be set according to the area that the drone needs to protect. In this embodiment, the number of positive conductors 21 and negative conductors 22 is not limited.

[0057] Exemplarily, five groups of positive conductors 21 and negative conductors 22 can be set. When the drone is interfered by an electromagnetic pulse, the nonlinear zinc oxide resistor 24 in the drone anti-interference device 2 absorbs the energy generated by the electromagnetic pulse and releases the excess energy into five closed loops to effectively absorb the energy of the electromagnetic pulse.

[0058] In addition, the distance between the positive conductor 21 and the negative conductor 22 can also be determined according to the actual situation of the drone. Specifically, the distance between the positive conductor 21 and the negative conductor 22 can be relatively small in the area that needs to be protected to improve the anti-interference ability.

[0059] Furthermore, in practical applications, an electrically controlled switch can be provided in the closed loop formed by each group of positive conductors 21 and negative conductors 22 and the electrode 23, and the electrically controlled switch is in a normally open state. Accordingly, the UAV adaptively closes a corresponding number of electrically controlled switches according to the intensity of the electromagnetic pulse, so that a corresponding number of closed loops absorb the energy of the electromagnetic pulse, thereby effectively protecting each component in the UAV anti-interference device 2 and avoiding damage to the anti-interference device.

[0060] It is understandable that when at least two groups of positive conductors 21 and negative conductors 22 are provided, at least two groups of positive conductors 21 and negative conductors 22 are arranged crosswise, and the intersection of each group of positive conductors 21 and negative conductors 22 is insulated. This arrangement can effectively save space and avoid short circuits.

[0061] Figure 3 A schematic diagram of the structure of an anti-interference device for a drone provided in an embodiment of the present application Figure 2 , based on the above-mentioned embodiments, this embodiment further illustrates the anti-interference device.

[0062] Specifically, Figure 3 As shown, in this embodiment, the electrode 23 is specifically an electrode sheet, there are multiple electrode sheets, and multiple nonlinear zinc oxide resistor sheets 24 are provided, which are inserted between the electrode sheets at intervals and fastened in series, and the multiple electrode sheets and multiple nonlinear zinc oxide resistor sheets 24 are used to be fastened to the drone body 1.

[0063] It is understandable that the area that needs to be protected by the drone is different, and the energy of electromagnetic pulse absorption that needs to be set is different. Correspondingly, the number of electrode sheets and nonlinear zinc oxide resistors 24 set is also different. Therefore, the number of electrode sheets and nonlinear zinc oxide resistors 24 is not limited in this embodiment.

[0064] In this embodiment, the nonlinear zinc oxide resistor 24 is arranged at intervals between multiple electrode sheets. When an abnormal situation occurs in the closed loop, such as overvoltage or overcurrent, the nonlinear zinc oxide resistor 24 can provide protection at multiple positions, respond quickly and limit or cut off the current, thereby more effectively protecting the various components of the drone anti-interference device 2.

[0065] It is understandable that the nonlinear zinc oxide resistor 24 and the electrode 23 may generate heat in the process of consuming electromagnetic pulses. Therefore, in this embodiment, the nonlinear zinc oxide resistor and the electrode 23 are wrapped with insulating material to prevent the electrode 23 and the nonlinear zinc oxide resistor 24 from being damaged due to overheating.

[0066] In addition, in this embodiment, the UAV anti-interference device also includes an insulating plate 25, and the positive and negative wires are fastened to the insulating plate 25. Specifically, screws, bolts, or adhesives can be used to fasten the wires to the insulating plate 25 to ensure the mechanical stability of the wires, which is not limited in this embodiment. By making the UAV anti-interference device 2 include an insulating plate 25, the UAV anti-interference device 2 can be applied to UAVs whose shells are not made of insulating materials and UAVs whose shells are made of insulating materials, thereby improving the applicability of the UAV anti-interference device 2.

[0067] like Figure 2 and Figure 3 As shown, the positive conductor and the negative conductor 22 are laid flat on the insulating plate 25. In this embodiment, the intersections of the positive conductor 21 and the negative conductor 22 are all insulated. Based on this arrangement, the UAV anti-interference device 2 saves more space and avoids short circuits.

[0068] It is understandable that the nonlinear zinc oxide resistor 24 needs to be maintained or replaced after being used for a period of time to ensure the energy absorption performance of the drone anti-interference device 2.

[0069] Therefore, further, in this embodiment, the UAV anti-interference device also includes a sensing unit, a control unit and an alarm unit. Specifically, the sensing unit is connected to the nonlinear zinc oxide resistor 24 to monitor the real-time data of the nonlinear zinc oxide resistor 24.

[0070] The real-time data includes at least one of voltage, current, temperature and leakage current. The corresponding sensing unit should include at least one of a device for monitoring voltage, a device for monitoring current, a device for monitoring temperature and a device for monitoring leakage current.

[0071] The input end of the control unit is connected to the output end of the sensing unit, and is used to send an alarm instruction to the alarm unit when the real-time data does not meet the preset range. Specifically, the control unit includes a comparator, which is used to compare the real-time data with the stored preset range, and further, when the real-time data does not meet the preset range, the stored alarm instruction is sent to the alarm unit.

[0072] The input end of the alarm unit is connected to the output end of the control unit to obtain an alarm instruction, and when receiving the alarm instruction, execute a preset alarm action. Specifically, the alarm action may be sending a replacement prompt to the user terminal, or prompting through a buzzer or indicator light.

[0073] Through this configuration, the state of the nonlinear zinc oxide resistor 24 can be known in real time, which is conducive to timely replacement when it needs to be replaced, so as to ensure the performance of the anti-interference device.

[0074] In this embodiment, the UAV anti-interference device 2 also includes a communication unit, and the input end of the communication unit is connected to the output end of the control unit to obtain and transmit the alarm instruction. Optionally, the output end of the communication unit is connected to the input end of the user terminal, and can be connected wirelessly via Bluetooth or mobile network, etc. This is not limited in this embodiment, as long as the input end of the user terminal can be connected to the output end of the communication unit, so that the user terminal can receive the alarm instruction transmitted by the communication unit, so that the nonlinear zinc oxide resistor 24 can be replaced in time.

[0075] Optionally, the output end of the communication unit can also be connected to the input end of the drone control module, which is helpful for the drone to know that the nonlinear zinc oxide resistor 24 needs to be replaced, thereby reducing the risk of damage due to electromagnetic pulse interference during use. This is not limited in this embodiment.

[0076] As an example, the sensing unit included in the drone anti-interference device 2 in this embodiment specifically includes a device for monitoring voltage, a device for monitoring current, a device for monitoring temperature, and a device for monitoring leakage current. Based on this, when the drone anti-interference device 2 obtains real-time data including voltage, current, temperature, and leakage current, it compares the voltage with the voltage preset range stored in the comparator, the current with the current preset range stored in the comparator, the temperature with the temperature preset range stored in the comparator, and the leakage current with the leakage current preset range stored in the comparator to determine whether the above four items all meet the corresponding preset ranges. If not, an alarm instruction is transmitted to the alarm unit connected thereto to prompt the user to replace the nonlinear zinc oxide resistor 24, so that the nonlinear zinc oxide resistor 24 is always kept in a better state, which is conducive to ensuring the performance of the drone anti-interference device 2.

[0077] It is understandable that in order to prevent the above-mentioned sensing unit and communication unit from being interfered by electromagnetic pulses, shielding materials such as conductive rubber may be provided on their surfaces, which is not limited in this embodiment.

[0078] The present application also provides a drone, Figure 4 A schematic diagram of the structure of a drone provided in an embodiment of the present application is shown in FIG. Figure 4 The drone shown includes the drone anti-interference device 2 in the above embodiment, and the drone anti-interference device 2 is arranged at a position on the outer surface of the drone that needs to be protected.

[0079] Specifically, the drone can be of any shape, as long as the conductor is made of a flexible conductive material. In addition, the shell of the drone can be made of an insulating material or not, as long as the drone anti-interference device 2 includes an insulating plate 25. This embodiment does not limit the electronic device.

[0080] It can be understood that the drone can be a quadcopter, a multi-axis drone, a fixed-wing drone, etc., as long as the drone anti-interference device 2 can cover the location of its flight control module and other key circuit boards. This is not limited in this embodiment.

[0081] It is understandable that there may be multiple locations on the drone body 1 that need to be protected. Figure 4 As shown, drone anti-interference devices can be respectively installed at multiple locations that need to be protected. In multiple locations that need to be protected, based on the size of the area that needs to be protected, the overall area of ​​the drone anti-interference device installed accordingly is also different, which is not limited in this embodiment. Specifically, Figure 4 The area within the middle dotted line is the location of the UAV anti-interference device 2.

[0082] As an example, in Figure 4 When the shell of the drone shown is not made of insulating material, the position and structure of the corresponding drone anti-interference device 2 include positive wire, negative wire, electrode sheet, nonlinear zinc oxide resistor 24, and insulating plate 25 in sequence. The positive wire is connected in series with the negative wire, and multiple wires are arranged and fastened on the surface of the insulating plate 25. The positive wire and the negative wire are made of conductive material. The positive wire and the negative wire are respectively connected in series with the positive and negative electrodes of the electrode sheet. The nonlinear zinc oxide resistor 24 is inserted into the electrode sheet at intervals to form a closed circuit, which is used to divide electromagnetic pulses, conduct current, and consume the energy of electromagnetic pulses. This structure is connected to form the drone anti-interference device 2.

[0083] Specifically, the positive and negative wires are fastened to the front side of the insulating plate 25, and the back side of the insulating plate 25 is tightly placed on the shell of the drone, wherein the insulating plate 25 is made of a flexible insulating material and can be bent to adapt to the shape of the drone.

[0084] The positive and negative wires are laid flat on the insulating board, and the intersections of the positive and negative wires are all insulated. In practical applications, different groups of wires are set according to the area to be protected. The positive and negative wires are arranged at intervals, and the intervals of positive and negative wires divide the electromagnetic pulse beam into different electromotive forces, forming multiple closed loops.

[0085] exist Figure 4 When the shell of the drone shown is made of insulating material, the insulating plate 25 in the drone anti-interference device 2 can be removed, and the positive and negative wires can be placed in the drone insulating shell as a whole. The installation direction can be horizontal and vertical, up and down, left and right, and front and back. The installation position can also cover the entire shell to achieve the effect of shielding electromagnetic pulses.

[0086] When installing the drone anti-interference device 2, a curved layout is adopted so that the positive and negative wires bypass the various sensor probe holes reserved for the drone and the locations of the installation ports, so that the drone anti-interference device 2 can be applied to drones of any geometric shape on the current market, including quadcopters, multi-axis drones, fixed-wing drones, etc., as long as the drone anti-interference device 2 covers its flight control module and key circuit boards.

In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described.
