These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present disclosure, the first information may also be called second information, and similarly, the second information may also be called first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to determining."

In related technologies, power consumption is generally controlled based on battery power. When the power is lower than a certain threshold (for example, 20% of the total power), the drone is switched from a high-power mode to a low-power mode. The switching granularity of this power consumption control method is relatively coarse, and the power consumption control effect is poor.

In order to solve the above problems, the present disclosure provides a power consumption control method for a UAV. As shown in Figure 1, the UAV is communicated with image transmission glasses; the method includes:

Step 101: Obtain the flight status of the drone and the wearing status of the image transmission glasses;

Step 102: Determine the target working scenario that matches the flight state and the wearing state;

Step 103: Determine the power consumption mode of the drone according to the target working scenario;

Step 104: Control the power consumption of the drone based on the power consumption mode.

The drone and the image transmission glasses in the embodiment of the present disclosure can communicate using any wireless communication method, such as Bluetooth communication method, infrared communication method, 5G communication method, etc. The drone can be equipped with an image acquisition device, such as a camera, to collect images of the environment surrounding the drone. The collected images can be transmitted to the image transmission glasses through the image transmission system on the drone. After users wear image transmission glasses, they can view the images transmitted by the image transmission system and experience the first-person perspective of the drone.

This method can be executed by the control system on the drone. In step 101, the flight status of the drone and the wearing status of the image transmission glasses can be monitored. Among them, the flight status of the drone is used to indicate whether the drone is flying, including the ready-to-fly state and the aerial status. The ready-to-fly status indicates that the drone is not flying, that is, the drone is on the ground and ready to fly; the aerial status indicates that there is no one The plane is flying. The flight status of the UAV can be obtained through the flight system on the UAV. For example, the flight system can obtain information such as the UAV's blade speed, the UAV's position, the UAV's moving speed, etc., and then determine the UAV's flight status based on this information. The flight status of the human and machine. The wearing status of the image transmission glasses is used to determine whether the image transmission glasses are being worn, including the worn state and the unworn state. Sensors, such as depth sensors, proximity light sensors, infrared sensors, etc., can be installed on the image transmission glasses to sense the wearing status of the image transmission glasses.

The flight status of the drone and the wearing status of the image transmission glasses can be obtained at regular intervals, or they can also be obtained when triggered by a preset event. The drone and the image transmission glasses can actively report their status to the control system, and the control system can also actively query the flight status of the drone and the wearing status of the image transmission glasses. For example, drones and image transmission glasses can report their own status at intervals, or they can report the changed status only when their own status changes. In addition, other methods can be used to obtain the flight status of the drone and the wearing status of the image transmission glasses. The methods used can be set according to actual needs, and will not be listed here.

In step 102, after the flight state and the wearing state are determined, the target working scene of the UAV can be comprehensively determined based on the flight state and the wearing state. Since both the flight status and the wearing status are considered when determining the target work scene, the process of determining the work scene is more accurate. Moreover, the determined target working scene matches the flight status of the drone and the wearing status of the image transmission glasses. Therefore, the determined target working scene is more in line with the working status and needs of the drone.

In some embodiments, the work scene can be divided into a first work scene and a second work scene according to the image transmission code rate. Among them, the image transmission code rate of the first working scenario is higher than the image transmission code rate of the second working scenario. Therefore, the first working scenario can also be called a high bit rate scenario, and the second working scenario can also be called a low bit rate scenario. . In other embodiments, the work scene can be divided into a flight scene, a ground scene and a bombing scene according to whether the drone is in a normal flight state. Among them, in the flight scene, the drone flies normally in the air; in the ground scene, the drone does not fly; in the bombing scene, the drone's flight status is abnormal. For the sake of simplicity, the ground scene and the bombing scene can be collectively referred to as the third work scene.

Further, the ground scene specifically includes at least one of the following scenes:

In the scene of stopping the propellers and waiting to fly, the propellers of the UAV are in a stopped rotating state and the UAV has not taken off. The scene of stopping the propellers and waiting to fly can be further divided into the far-field stopping and waiting-to-fly scene and the near-field stopping and waiting-to-fly scene; in the far field In the scenario of stopping the propellers and waiting to fly, the UAV may malfunction and land at a far distance. Therefore, in the scenario of stopping the propellers and waiting to fly in the far field, it is often necessary to keep the image transmission system working; in the scenario of stopping the propellers and waiting to fly in the near field, it is often necessary to keep the image transmission system working. , you can keep the image transmission system working or turn off the image transmission system;

Upgrade scenario (also called one-click upgrade scenario) is used to upgrade the system or firmware; the system can include but is not limited to the power system, control system, flight system and/or image transmission system on the drone;

Download and playback scenarios are used for media data download and playback; the media data may include but are not limited to image data historically captured by the image collection device on the drone and data related to the image data, such as the time when the image was captured. Information, the position information of the drone when the image was captured and/or the shooting parameters of the image collection device, etc., may also include audio data and logs, which can be downloaded and played back through the drone's application program (APP);

Log export scenario, used for log export; the log can be a log on the drone's application program (APP), used to record the status parameters (for example, temperature), alarm information and /or abnormal events, etc.;

U disk mode scenario is used to read and write data stored inside the drone; the data can include but is not limited to data collected by various sensors on the drone and various log data, data collected by sensors Including but not limited to image data collected by vision sensors, temperature data collected by temperature sensors, pressure data collected by pressure sensors, etc.;

The ground photography and video recording scene is used to take photos or videos through the image collection device on the drone when the drone is parked on the ground.

In addition to the work scenarios listed above, work scenarios can also be divided according to other conditions, or at least one of the above work scenarios can be further divided into multiple sub-scenarios according to actual needs, which will not be listed here.

Different working scenarios are matched with different flight states of the drone and/or different wearing states of the image transmission glasses. For example, when the image transmission glasses are being worn, the image transmission system on the drone is often expected to transmit images at a higher image transmission bit rate, that is, the drone is expected to work in a high bit rate scenario. However, when the drone is ready to fly, due to the difficulty in dissipating heat, the drone is often expected to work in a low bitrate scenario to reduce the risk of the drone being overheated.

Therefore, in some embodiments, the target working scene is determined to be a high bit rate scene only when the drone is in the air and the image transmission glasses are in the worn state. If the drone is ready to fly or the image transmission glasses are not worn, the target working scene is determined to be a low bit rate scene, as shown in Figure 2. In this way, the target work scenario can take into account the heat dissipation of the drone and the bit rate transmission requirements of the image transmission.

Further, as shown in Figure 3, the flight state of the UAV can be determined first, and when the flight state is the ready-to-fly state, the target working scene is directly determined to be a low bit rate scene. When the flight state is the air state, the target working scene is determined based on the wearing state of the image transmission glasses. Specifically, when the wearing state is the unworn state, it can be determined that the target working scene is a low code rate scene. When the wearing state is the worn state, it can be determined that the target working scene is a high code rate scene. In this way, priority can be given to ensuring the heat dissipation of the drone, reducing damage caused by poor heat dissipation of the drone, and extending the service life of the drone. On the basis of ensuring heat dissipation, the code rate transmission requirements of image transmission are also taken into consideration.

In some embodiments, in addition to determining the target work scene based on the flight status of the drone and the wearing status of the image transmission glasses, the target work scene can also be determined based on trigger information used to trigger work scene switching. Specifically, when the target working scene is a low code rate scene, if the trigger information for triggering the working scene switching is obtained, the target working scene can be determined to be the third working scene.

As shown in Figure 4, the information on the arrow is the trigger information. For example, when the UAV is in a scene where the propellers are stopped and ready to fly, if the trigger information issued by the upgrade center indicating the start of the upgrade is received, the target working scene switches to the upgrade scene, which can be controlled through the controls on the UAV or remote control. One-click upgrade of the system or firmware on the drone. In the upgrade scenario, if the trigger information issued by the upgrade center indicating the termination of the upgrade is received, the target working scenario switches back to the propeller-stopped and ready-to-fly scenario.

When the drone is in the stop-and-fly scenario, if a blackbox notification is received, the target working scenario switches to the log export scenario. In the log export scenario, if a blackbox notification is received, the target work scenario switches back to the stop propellers and standby scenario.

When the UAV is in a scene where the propellers are stopped and ready to fly, if the trigger information to enter playback/download issued by the camera is received, the target working scene switches to the download playback scene. In the download and playback scenario, if the trigger information issued by the camera to exit playback/download is received, the target working scene switches back to the stop propellers and ready-to-fly scenario.

When the drone is in a stop-and-fly scenario, a log export scenario, or a download and playback scenario, if the motor on trigger information released by the flight system is received, the target working scenario switches to a low bit rate scenario. In a low bitrate scenario, if the motor off trigger information issued by the flight system is received and log export is currently in progress, the target working scene switches back to the log export scene; if only the motor off trigger information issued by the flight system is received, and If the log is not currently being exported, the target working scene will switch back to the scene of stopping the propellers and waiting to fly; if the motor off trigger information issued by the flight system is received and playback/downloading is currently in progress, the target working scene will switch back to the downloading playback scene.

When the UAV is in a scene where the propellers are stopped and ready to fly, if a trigger message for USB connection is received, the target working scene switches to the USB disk mode scene. In the USB disk mode scenario, if a trigger message to disconnect the USB is received, the target working scenario switches back to the propeller-stop and ready-to-fly scenario.

When the drone is in a scene where the propellers are stopped and ready to fly, if a trigger message is received from the image acquisition device (for example, a camera) on the drone to start taking pictures/videos, the target working scene is switched to a ground photography and video recording scene. In the ground photography and video recording scenario, if the camera receives the trigger information of the end of photography/video recording, the target working scene switches back to the scene of stopping the propellers and waiting to fly.

When the drone is in a low bit rate scene, if it receives the motor off trigger information issued by the flight system and is currently taking photos/videos, the target working scene will switch to the photo and video scenes. In the photo and video scene, if the motor on trigger information issued by the flight system is received, the target working scene switches back to the low bit rate scene.

When the UAV is in a high bit rate scenario or a low bit rate scenario, if it receives abnormal flight status trigger information released by the flight system, the target working scene will switch to a bombing scenario.

In some embodiments, a default working scene can be set in advance. In the initial situation, the default working scene is entered first, and then based on the flight status of the drone, the wearing status of the image transmission glasses, and the trigger information, the default working scene is entered. Transition to target work scenario.

In step 103, after the target working scenario is determined, the power consumption mode can be determined according to the target working scenario. In this way, the determined power consumption mode matches the working scenario of the drone, so that the power consumption requirements of the current working scenario can be met. , without causing excessive waste of power consumption. The corresponding relationship between various working scenarios and power consumption modes can be set in advance. After the target working scenario is determined, the corresponding power consumption mode can be found from the corresponding relationship according to the target working scenario.

In some embodiments, the power consumption mode includes power consumption modes of several subsystems on the drone. The subsystems may include, but are not limited to, camera systems, flight control systems, and/or image transmission systems, etc. The power consumption mode of the subsystem may include multiple power consumption levels. For example, the power consumption mode of a subsystem can be divided into three power consumption levels, respectively recorded as S0, S1 and S2, and the corresponding power consumption of S0, S1 and S2 decreases in sequence. Those skilled in the art can understand that the number and representation of power consumption levels are not limited thereto. For example, two power consumption levels or four power consumption levels may be used. The power consumption modes of different subsystems can use the same or a different number of power consumption levels. For example, the power consumption mode of the camera system can use two power consumption levels, and the power consumption mode of the flight control system can use four power consumption levels. An optional situation of each subsystem and its corresponding power consumption mode is shown in the following table:

In some embodiments, the power consumption mode of at least one of the subsystems is dynamically adjustable. For example, the power consumption level can be dynamically adjusted based on the status parameters of the drone (eg, voltage parameters, temperature parameters, and/or power parameters, etc.). For example, in a low bitrate scenario, the power consumption level of the camera system is originally set to S0, but if it is detected that the battery power is too low (for example, less than 10% of the total power), and/or the drone temperature is too high ( For example, if a certain temperature threshold is exceeded), the power consumption level of the camera system is adjusted to S1. In this way, the power consumption level can be adapted to the status parameters of the drone, further improving the power consumption control effect.

In addition, the dynamically adjustable power consumption mode may also include but is not limited to at least one of the following situations:

The number of power consumption levels included in the power consumption mode of the subsystem is adjustable. For example, the number of power consumption levels included in a subsystem can be adjusted from 3 to 2 (i.e., reduced), or from 4 to 5 (i.e., increased). ). In this way, a variety of granular power consumption control methods can be achieved.

The power consumption mode of the subsystem includes parameters of at least one power consumption level that are adjustable. For example, the range of the voltage parameters of a power consumption level can be set to [V1, V2], so that under this power consumption level, Dynamically adjust the voltage parameters of the subsystem within the range of [V1, V2]. By setting the parameters of the power consumption level to be adjustable, the granularity of the power consumption adjustment method can be further reduced, and the current power consumption mode can be adapted to the working scenario of the drone as much as possible.

In addition to the situations listed above, other methods can also be used to dynamically adjust the power consumption mode of at least one of the subsystems, which will not be listed here.

In step 104, after the power consumption mode is determined, the power consumption of the drone can be controlled based on the determined power consumption mode. If the initial power consumption mode of the drone matches the power consumption mode determined based on the target working scenario, there is no need to adjust the initial power consumption mode. If the initial power consumption mode of the drone does not match the power consumption mode determined based on the target working scenario, the power consumption mode of the drone can be switched from the initial power consumption mode to the power consumption mode determined based on the target working scenario.

When controlling power consumption, the switching status of the sensor on the drone, the switching status of the clock signal, the adaptive status of the radio frequency module and/or the working mode of the image transmission chip can be controlled based on the determined power consumption mode. The sensors may include but are not limited to vision sensors, TOF sensors, ACC sensors, etc. A possible implementation of the power consumption control method of each subsystem is shown in the following table:

For the flight system, when it is at the S0 power consumption level, the business operates normally and the visual sensor switch is adaptive; when it is at the S1 power consumption level, it enters the low power consumption mode, and the relevant visual sensors, TOF, and ACC are turned off or enter low power mode. consumption mode.

For the camera, it is hoped to achieve a balance (tradeoff) between image quality and power consumption. Therefore, when it is at the S0 power consumption level, the business operates normally, and the main camera sensor and IP clk (IP clock signal) switch are adaptive; When it is at the S1 power consumption level, the business works normally, but only high-definition images are transmitted. For example, 1080P images are transmitted at a frame rate of 30fps, and the unused IP clk is turned off; when it is at the S2 power consumption level, the business does not When working, the clock signals of the main camera sensor and related IP are all turned off.

For the image transmission system, it is hoped to realize adaptive adjustment of power devices such as FEM. Therefore, when it is at the S0 power consumption level, the image transmission chip works in the normal working mode and the RF module adapts; when it is at the S1 power consumption level, the image transmission system The transmission chip works in low power consumption mode, and the radio frequency module is adaptive; when it is at the S2 power consumption level, the image transmission chip subsystem is powered off.

In some embodiments, when the drone enters the low-power mode, the air interface link between the drone and the image transmission glasses will be affected, which may cause the uplink messages sent by the image transmission glasses to the drone to be blocked. , therefore, a control signal can also be sent to the image transmission glasses, and the control signal is used to change the power consumption mode of the image transmission glasses. For example, the power consumption mode of the image transmission glasses can be adjusted to a low power consumption mode. In this way, the probability of the image transmission glasses sending invalid signals can be reduced, the power consumption of the image transmission glasses can be reduced, and the battery life of the image transmission glasses can be improved.

In this disclosed embodiment, the target working scenario of the drone is jointly determined by combining the wearing status of the image transmission glasses and the flight status of the drone, and the power consumption mode of the drone is determined based on the target working scenario, thereby achieving The power consumption of the drone is controlled through "sky-ground linkage" between the drone end (i.e., the air end) and the image transmission glasses (i.e., the ground end). Compared with the method of switching between high power consumption mode and low power consumption mode based on electricity, it can make the power consumption mode of the drone more suitable for the working scene, and the switching granularity of the power consumption mode is finer. , which can effectively improve the power consumption control effect, improve the endurance of the drone, and thereby improve the user experience.
