[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0038] At present, most tethered drones use a power supply to provide long-term power for the tethered drone. The power supply can be directly connected to the mains power grid to initially ensure the stability of the power supply for the tethered drone. At the same time, an onboard backup power supply is also provided as a power guarantee after the power supply of the tethered drone is powered off. However, this solution has the following disadvantages. First, the onboard backup power supply will occupy the space of the tethered drone and increase the complexity of setting the circuit board of the tethered drone. Secondly, the onboard backup power supply will occupy the overall weight of the tethered drone, which will increase the working power of the tethered drone during normal work, thereby increasing the power consumption of the tethered drone. Thirdly, the onboard backup battery also needs to be equipped with additional charging equipment, which will increase the manufacturing cost of the tethered drone and reduce the portability of the tethered drone.

[0039] The embodiment of the present application discloses a power supply system for a tethered drone, which ensures the stability of the operation of the tethered drone and improves the practicality of the tethered drone. Detailed descriptions are given below.

[0040] Figure 1 Schematic diagram of the structure of the power supply system of the tethered drone disclosed in the embodiment of the present application. Figure 1 As shown, the power supply system of the tethered drone may include a power supply, a backup power supply, a transmission circuit and a detection module.

[0041] In one embodiment, both the power supply and the backup power supply can be used to power the tethered drone, wherein the power supply can be a source of long-term stable power generation, for example, the power supply can be a mains power grid. The backup power supply can be a power supply that stores a certain amount of power, specifically, the backup power supply can be a 48V backup battery. The backup power supply can also be connected to the power supply, and when the power supply system of the tethered drone detects that the power of the backup power supply is lower than a preset power threshold, the backup power supply can be charged by the power supply to ensure that the backup power supply has sufficient power.

[0042] Optionally, the transmission circuit can be used to transmit the current output by the power supply or the backup power supply. When the power supply fails, the current output by the backup power supply can be transmitted to maintain the normal operation of the tethered drone.

[0043] As an optional implementation, the detection module can be used to detect the current of the transmission circuit to obtain a current state signal; if it is determined that the current state signal indicates that the current is abnormal, the current of the backup power supply is transmitted to the tethered drone through the boost module; if it is determined that the current state signal indicates that the current is normal, the current of the power supply is transmitted to the tethered drone. Among them, the current state signal can be a signal used to only transmit the current state in the circuit, and there can be two types of current state signals, namely normal signals and abnormal signals, wherein the normal signal can be used to indicate that the current in the power supply system of the tethered drone is normal, and the abnormal signal can be used to indicate that the current in the power supply system of the tethered drone is abnormal. Optionally, the boost module is connected to the circuit between the backup power supply and the tethered drone, and can also be set in the transmission circuit for transmitting the power output by the backup power supply, so that the current output by the backup power supply is boosted before being transmitted to the tethered drone.

[0044] In some embodiments, the transmission circuit further includes a bidirectional optocoupler unit, which can be used to isolate the current of the high-voltage output end of the transmission circuit. Specifically, the bidirectional optocoupler unit can be used to isolate the circuit that transmits the power output of the backup power supply and the circuit that transmits the power output of the power supply, so that the detection module can accurately detect the circuit that transmits the power output of the backup power supply, or can accurately detect the circuit that transmits the power output of the power supply. Optionally, the bidirectional optocoupler unit can be composed of one or more optocouplers, which are used to isolate the circuit that needs to be isolated.

[0045] Furthermore, the detection module also includes a signal detection unit, which can be used to detect the current at the high-voltage output end of the transmission circuit to obtain a current state signal. Among them, the transmission circuit can also be provided with an electronic device required for boosting, so as to boost the current in the transmission circuit to obtain the high-voltage output end of the transmission circuit. The high-voltage output end of the transmission circuit can be directly connected to the tethered drone to transmit high-voltage current to the tethered drone. For example, if the tethered drone is powered by a power supply, assuming that the power supply is 220V, the transmission circuit can boost the current of the 220V power supply to 400V and then output it to the tethered drone. If the tethered drone is powered by a backup power supply, assuming that the backup power supply is 48V, the current can be boosted to 400V by the boost module connected to the backup power supply, and then output to the transmission circuit, so that the transmission circuit transmits the current to the tethered drone, thereby providing a high-voltage and stable current for the tethered drone. The signal detection unit may include a microprocessor and a current sensor, wherein the microprocessor is connected to the current sensor, the microprocessor may control the current sensor to collect current information, the current sensor monitors the current, and the processor collects and processes the current information collected by the current sensor to obtain a current state signal.

[0046] Figure 2 FIG. 1 is a schematic diagram of a structure in which a power supply and a backup power supply are connected to a tethered drone in an embodiment. Figure 2 As shown, the power supply can be a 220V mains power supply. The power supply performs leakage detection on the current output by the power supply through the leakage protection / AC power supply detection module, thereby avoiding leakage of the power supply and improving the safety of the power supply system of the tethered drone. After the current output by the power supply passes through the leakage protection / AC power supply detection module, the output current can be boosted to convert the 220V current into a 400V current, and then transmitted to the tethered drone, thereby providing the tethered drone with the voltage required for operation. In the circuit for transmitting current of the power supply, a hardware light-off circuit can be provided, and the AC state collected by the leakage protection module can be controlled to turn off the tethered drone load through the circuit under abnormal conditions. The backup power supply can be a 48V backup battery, which can boost the 48V voltage output by the backup power supply to a 400V current through the boost module, and then transmit the boosted 400V current to the tethered drone, thereby maintaining the normal operation of the tethered drone.

[0047] As an optional implementation, the power supply system of the tethered drone includes a backup power supply and a power supply, wherein the current output by the backup power supply and the power supply can reach the tethered drone through two different lines, that is, the tethered drone can be powered by dual lines. Figure 3FIG. 1 is a functional block diagram of switching between power supply and backup power supply in one embodiment. Figure 3 As shown, the power supply system of the tethered drone includes an AC-DC power module, a DC-DC backup power module, a dual-channel switching circuit, a power carrier module, a high-voltage discharge circuit, and a hardware light-off control circuit. Among them, the power supply can be an AC-DC power module, and the AC-DC power module is an AC-DC power module with a main output to provide the power required by the tethered drone. The backup power supply can be a DC-DC backup power module, and the DC-DC backup power module is a DC-DC boost power module with a backup output to maintain the backup power supply for the flight function of the tethered drone. The dual-channel switching circuit outputs the two output ends in parallel through a high-power anti-reverse diode to achieve seamless switching, and can prevent the output voltage from being affected by the power module, such as a single module failure and reducing the output voltage, resulting in failure to work properly. The power carrier module can use the power carrier communication function to communicate with the tethered drone. The high-voltage discharge circuit can open the circuit to quickly discharge the high voltage when the high-voltage output is turned off to prevent the high voltage from remaining and accidentally electric shock when the staff is using it. The hardware light-off control circuit can control the drone load to shut down through the circuit under abnormal conditions through the AC state collected by the leakage protection module.

[0048] In some embodiments, the detection module can also be used to detect the voltage of the tethered drone to obtain voltage data; if it is determined that the voltage data is lower than a preset voltage threshold, the current of the backup power supply is transmitted to the tethered drone through the boost module. The voltage data can be used to describe the voltage condition in the transmission circuit. If it is determined that the voltage data is lower than the preset voltage threshold, it can indicate that the current output by the power supply is abnormal, for example, the current output by the power supply is too small, or it indicates that the current output by the power supply is abnormal during the boost process and cannot reach the voltage required for the tethered drone to work. Therefore, the current of the backup power supply can be transmitted to the tethered drone through the boost module to ensure the normal operation of the tethered drone. If it is determined that the voltage data is greater than or equal to the preset voltage threshold, it indicates that the current output by the power supply can meet the normal operation of the tethered drone, and the tethered drone can continue to be powered by the power supply.

[0049] In an embodiment of the present application, the power supply system of the tethered drone may include a power supply and a backup power supply, a transmission circuit and a detection module, wherein the power supply and the backup power supply are used to power the tethered drone; the transmission circuit is used to transmit the current output by the power supply or the backup power supply; the detection module is used to detect the current of the transmission circuit to obtain a current state signal; if it is determined that the current state signal indicates that the current is abnormal, the current of the backup power supply is transmitted to the tethered drone through the boost module; if it is determined that the current state signal indicates that the current is normal, the current of the power supply is transmitted to the tethered drone. The power supply system of the tethered drone can transmit the current of the backup power supply to the tethered drone through the boost module when it is determined that the current state signal indicates that the current is abnormal, so as to maintain the subsequent flight operation of the tethered drone, and when it is determined that the current state signal indicates that the current is normal, the current of the power supply is transmitted to the tethered drone to ensure that the tethered drone can be connected to a stable power supply again, and the stable supply of electricity can be ensured without setting an onboard backup power supply in the tethered drone, which ensures the stability of the operation of the tethered drone and improves the practicality of the tethered drone.

[0050] Figure 4 Schematic diagram of the process of obtaining the current state signal in the embodiment of the present application. Figure 4 As shown, the step of obtaining the current state signal further includes the following steps:

[0051] Step S401, obtaining a current signal.

[0052] In some embodiments, the current signal can be used to reflect the current condition within a time period. A current sensor and a microprocessor may also be provided in the power supply system of the tethered drone, and the microprocessor may control the current sensor to obtain the current signal. Specifically, the microprocessor may control the current sensor to collect the current condition within a preset time length, thereby obtaining a current signal. For example, the microprocessor may control the sensor to collect the current condition within 0.01 seconds to obtain a current signal. The current sensor may be disposed in the power supply system of the tethered drone close to the microprocessor, or may be disposed at a location where current signal collection is required, which is not limited here. By real-time collection of the current condition by the current sensor, the microprocessor can quickly obtain the current signal, thereby providing a technical basis for the microprocessor to quickly process the current signal.

[0053] Step S402: extracting features from the current signal through a microprocessor to obtain current extraction features.

[0054] In some embodiments, the power supply system of the tethered drone can perform time domain feature extraction processing, frequency domain feature extraction processing or time-frequency domain feature extraction processing on the collected current signal through a microprocessor to obtain current extraction features. Specifically, the time domain feature extraction processing can be to analyze the time characteristics of the current signal. Common time domain features include maximum value, minimum value, mean value, standard deviation, root mean square value, skewness, kurtosis, etc. The frequency domain feature extraction processing can be to convert the time domain signal into a frequency domain signal through Fourier transform, and then extract the frequency domain features. Common frequency domain features include centroid frequency, average frequency, frequency root mean square, frequency variance, etc. The time-frequency domain feature extraction processing is to combine the time domain and frequency domain features for comprehensive analysis. Common methods include wavelet packet analysis and EMD signal analysis. By extracting the features of the current signal through the microprocessor to obtain the current extraction features, the current signal classification, fault diagnosis and other tasks can be effectively performed, thereby improving the accuracy of the current signal processing.

[0055] Step S403: Analyze the current extraction characteristics through the microprocessor to obtain a current state signal.

[0056] In some embodiments, the current extraction features are analyzed by a microprocessor, and the current extraction features can be classified to obtain a current state signal indicating whether the current in the power supply system of the tethered drone is normal or abnormal. Specifically, the current extraction features can be classified by a classifier preset in the microprocessor to obtain a classification result, and the current state signal can be determined according to the classification result. Among them, the classifier can be a support vector machine, etc., which is not specifically limited.

[0057] As an optional implementation, the detection module also includes an energy-saving unit, which can be used to control the tethered drone to enter an energy-saving mode if it is determined that the current status signal indicates that the current is abnormal, and transmit the current of the backup power supply to the tethered drone through the boost module. Among them, the energy-saving mode can be used to instruct the tethered drone to shut down some task processes to save power consumption. If it is determined that the current status signal indicates that the current is abnormal, it is necessary to extend the flight time of the tethered drone by reducing the power consumption of the tethered drone, thereby preventing the tethered drone from falling due to insufficient power.

[0058] Furthermore, the energy-saving unit can also be used to detect the power consumption of each energy-consuming hardware to obtain the power consumption data corresponding to each energy-consuming hardware; if it is determined that the power consumption data corresponding to the energy-consuming hardware is greater than the preset power consumption threshold, the energy-consuming hardware is controlled to be turned off. The tethered drone can record the power consumption data corresponding to each energy-consuming hardware in real time when working, and the energy-saving unit can query according to each energy-consuming hardware to obtain the power consumption data corresponding to each energy-consuming hardware. After determining the energy-consuming hardware with power consumption data greater than the preset power consumption threshold, the energy-consuming hardware with lower importance can be selected to be turned off according to the importance of each energy-consuming hardware, or the energy-consuming hardware with importance less than the preset important threshold can be turned off according to the importance of each energy-consuming hardware. If the importance is greater than or equal to the preset important threshold, the working state of the energy-consuming hardware can be maintained. For example, assuming that the importance of the energy-consuming hardware that maintains flight is set to be greater than the preset important threshold, and the importance of the energy-consuming hardware related to the light is set to be less than the preset important threshold, if the tethered drone is controlled to enter the energy-saving mode, the energy-consuming hardware related to the light can be turned off, and the energy-consuming hardware that maintains flight can continue to maintain the working state. By setting the importance of each energy-consuming hardware, it is possible to avoid shutting down energy-consuming hardware with high importance, which would seriously affect the working state of the tethered drone.

[0059] The power supply system of the tethered drone detects the power consumption of each energy-consuming hardware to obtain the power consumption data corresponding to each energy-consuming hardware; if it is determined that the power consumption data corresponding to the energy-consuming hardware is greater than the preset power consumption threshold, the energy-consuming hardware is controlled to be turned off. This can save the power consumption of the tethered drone to a large extent after the power supply of the tethered drone is abnormal, and can effectively avoid the problem of the tethered drone falling rapidly due to power supply abnormalities.

[0060] In some embodiments, the power supply system of the tethered drone further includes: an energy storage acquisition module, which is used to obtain energy storage information corresponding to the backup power supply; a warning module, which is used to generate a warning signal if it is determined that the energy storage information corresponding to the backup power supply is lower than a preset energy storage threshold, and send the warning signal to the central control platform. Among them, the energy storage information corresponding to the backup power supply can indicate the energy storage status of the backup power supply, and specifically, can be used to indicate the power status of the backup power supply. Optionally, the power supply system of the tethered drone may also include a ground-end control interface. If it is determined that the energy storage information corresponding to the backup power supply is lower than a preset energy storage threshold, a warning signal is generated, and the warning signal is displayed on the ground-end control interface, and the warning signal is sent to the central control platform, so that engineers who maintain the tethered drone can quickly know the energy storage status of the backup power supply. Figure 5 FIG. 1 is a functional block diagram of a ground terminal in an embodiment. Figure 5As shown, the ground-end function may include a leakage protection module, a control board, a main board and a button panel, as well as the connection between the leakage protection module, the control board, the main board and the button panel and the circuit. Through the connection of the ground-end function block diagram, the normal operation of each function can be ensured.

[0061] In some embodiments, the power supply system of the tethered drone includes an operation acquisition module and a voltage determination module; the operation acquisition module can be used to acquire the operation data corresponding to the current time period of the tethered drone; the voltage determination module can be used to determine the voltage data corresponding to the current transmitted by the transmission circuit according to the operation data. Among them, the operation data can be used to indicate the current operation status of the tethered drone, for example, it may include power consumption data, the amount of tasks performed, etc. The voltage determination module may store the correspondence between the operation data and the voltage data corresponding to the current transmitted by the transmission circuit, and the voltage determination module may directly determine the voltage data corresponding to the current transmitted by the transmission circuit according to the operation data and the correspondence. The power supply system of the tethered drone can determine the voltage data corresponding to the current transmitted by the transmission circuit according to the operation data, which can save the power consumption of the tethered drone, thereby also providing a technical basis for the tethered drone to work stably.

[0062] Furthermore, the voltage determination module is also used to predict the voltage data corresponding to the operation data in the next time period through the voltage calculation model obtained by training the historical operation data set; the transmission circuit is also used to transmit the current corresponding to the voltage data output by the power supply in the next time period. Among them, the voltage calculation model can be obtained by training the historical operation data set, and the historical operation data set includes multiple historical operation data and target voltage data corresponding to each historical operation data. The historical operation data set is input into the voltage calculation model to be trained, and the voltage calculation model to be trained calculates the predicted voltage data corresponding to each historical operation data according to each historical operation data. According to the error between the target voltage data corresponding to each historical operation data and the predicted voltage data corresponding to each historical operation data, the model parameters of the voltage calculation model to be trained are adjusted until the error is less than the preset error threshold, and the trained voltage calculation model is obtained. After the voltage calculation model obtained by training the historical operation data set predicts the voltage data corresponding to the operation data in the next time period, the power supply system of the tethered drone can control the current corresponding to the voltage data output by the power supply in the next time period, so that the transmission circuit transmits the current corresponding to the voltage data output by the power supply, so as to improve the planning of power supply for the tethered drone, thereby saving the power consumption of the tethered drone.

[0063] In an embodiment of the present application, a current signal is acquired, and features of the current signal are extracted by a microprocessor to obtain current extraction features. The current extraction features are analyzed by the microprocessor to obtain a current state signal, which can improve the accuracy of processing the current signal.
