Description

Technical Field

[0001] The embodiments of the present invention relate to the field of intelligent devices, and in particular to a fan control method, a fan and a storage medium. Background Art

[0002] Fans generally have two working states: one is directional working state, that is, blowing air continuously in a fixed direction; the other is uniform swing working state, that is, rotating at a fixed speed within the maximum swing angle range and blowing air continuously. The fan's working state switching and working or standby state are all controlled by the user.

[0003] However, the inventors have found that the fan has at least the following problems: if the user leaves the fan's air supply angle range for some reason and forgets to stop the fan from blowing, the fan continues to run and does ineffective work, resulting in waste. In addition, if the user leaves the air supply angle range, the user needs to control the fan to adjust to a suitable blowing angle by himself, and the fan's swing head working mode is not flexible and not automated enough. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a fan control method, a fan and a storage medium, so as to reduce the energy waste caused by the fan doing ineffective work and improve the flexibility of the fan steering control, so as to make the fan control more intelligent.

[0005] To solve the above technical problems, an embodiment of the present invention provides a fan control method, comprising: when the fan is in a directional working state, detecting whether a target object is identified within the wide-area viewing angle of a camera device in the current direction of the working device; wherein the wide-area viewing angle of the camera device changes with the direction of the working device; if the target object is identified, the working device is controlled to turn to the direction of the target object; in the process of controlling the working device to turn to the direction of the target object, if the target object is included in the air supply angle range of the working device during the turning process, the working device is controlled to stop rotating and keep supplying air, and if the target object never enters the air supply angle range of the working device during the turning process, the working device is controlled to reset and stop supplying air.

[0006] An embodiment of the present invention also provides a fan, comprising: a working device, an actuating module, a camera device, a base and a processor; the working device is connected to the base through the actuating module; the actuating module is arranged in the inner cavity of the base; the camera device is arranged on the working device, and the wide-area viewing angle range of the camera device changes with the direction of the working device; the processor is connected to the actuating module, and the processor is used to control the actuating module to drive the working device to rotate, so as to realize the above-mentioned fan control method.

[0007] An embodiment of the present invention further provides a computer-readable storage medium storing a computer program, wherein the computer program implements the above-mentioned fan control method when executed by a processor.

[0008] Compared with the prior art, the embodiment of the present invention, when the fan is in a directional working state, uses a camera device to identify whether there is a target object in front of the fan. If there is a target object, it is determined whether the target object is within the air supply angle range. If the target object is not within the air supply angle range regardless of how the fan rotates, it means that the fan air supply effect does not affect the target object and the fan is doing ineffective work. At this time, the control working device is reset and stops supplying air, reducing the energy waste of the fan doing ineffective work. In addition, if it is identified that there is a target object in front of the fan, and the target object can be within the air supply angle range by controlling the fan rotation, the control working device is turned to the direction of the target object, and the fan is intelligently controlled to turn to the appropriate position by itself.

[0009] In addition, when the fan is in a directional working state, if the target object is not identified within the wide-area viewing angle of the camera device in the current direction of the working device within the first preset time, the working device is controlled to rotate within the maximum swing angle range, and the wide-area viewing angle of the camera device is continuously identified during the rotation of the working device. Whether the target object is included in the wide-area viewing angle of the camera device; if the target object is identified during the rotation of the working device, the working device is controlled to turn to the direction of the target object so that the target object is within the air supply angle range of the working device; if the target object is not identified within the maximum swing range of the working device, the working device is controlled to reset and stop supplying air. In this way, when the fan is doing ineffective work in the directional working state, the fan can be automatically controlled to adjust to a suitable air supply angle, or the fan can be automatically controlled to stop supplying air to save power consumption.

[0010] In addition, if the number of identified target objects is greater than 1, the shortest straight-line distance between each target object and the working device is calculated; the direction of the target object with the smallest shortest straight-line distance is selected as the target direction of the working device, and the working device is controlled to turn to the target direction. In the case of multiple target objects in front of the fan, a suitable and fixed single object is selected to adjust the fan blowing direction, so as to avoid the influence of multiple target objects on the control of the fan, which is conducive to improving the accuracy of fan control.

[0011] In addition, after the working device is controlled to turn to the target direction, the method further includes: if the target object of the shortest straight-line distance is outside the air supply angle range under the current direction of the working device, the shortest straight-line distance between the target object within the wide-area viewing angle range of the camera device under the current direction of the working device and the working device is recalculated, and the target direction of the air blowing of the working device is re-determined based on the recalculated shortest straight-line distances. In this way, when there are multiple target objects, the fan can make effective output while reducing the operation of turning the fan.

[0012] In addition, when the fan is in the uniform swinging working state, if the target object is not recognized within the wide-area viewing angle of the camera device within the second preset time, the working device is controlled to reset and be in a standby state. In this way, when there is no object that needs to be blown in front of the fan, the fan automatically stops working to reduce energy consumption.

[0013] In addition, after the fan is in the standby state, the method further includes: if a target object is detected within the wide-area viewing angle of the camera device, the fan is restored to the uniform speed swinging working state. In this way, when an object requiring air blowing is detected in front of the fan, the fan can be woken up immediately and restored to the state before the standby state.

[0014] In addition, the function of the camera device to identify the target object is activated by triggering a voice command; and / or the switching of the identified target object is triggered by a gesture command.

[0015] In addition, after controlling the working device to turn toward the direction of the target object, it also includes: adjusting the preset wind speed according to the actual distance between the target object and the fan, and the corresponding relationship between the preset wind speed and the distance; wherein the adjusted wind speed is greater than or equal to the preset wind speed.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0023] The following embodiments are divided for the convenience of description and shall not constitute any limitation on the specific implementation of the present invention. The embodiments may be combined with each other and referenced to each other without contradiction.

[0024] An embodiment of the present invention relates to a fan control method, comprising: when the fan is in a directional working state, detecting whether a target object is identified within the wide-area viewing angle of a camera device in the current direction of a working device; wherein the wide-area viewing angle of the camera device changes with the direction of the working device; if the target object is identified, the working device is controlled to turn in the direction of the target object; in the process of controlling the working device to turn in the direction of the target object, if the target object is included in the air supply angle range of the working device during the turning process, the working device is controlled to stop rotating and keep supplying air, and if the target object never enters the air supply angle range of the working device during the turning process, the working device is controlled to reset and stop supplying air.

[0025] Compared with the prior art, the embodiment of the present invention, when the fan is in a directional working state, uses a camera device to identify whether there is a target object in front of the fan. If there is a target object, it is determined whether the target object is within the air supply angle range. If the target object is not within the air supply angle range regardless of how the fan rotates, it means that the fan air supply effect does not affect the target object and the fan is doing ineffective work. At this time, the control working device is reset and stops supplying air, reducing the energy waste of the fan doing ineffective work. In addition, if it is identified that there is a target object in front of the fan, and the target object can be within the air supply angle range by controlling the fan rotation, the control working device is turned to the direction of the target object, and the fan is intelligently controlled to turn to the appropriate position by itself.

[0026] The fan control rules of this implementation are described in detail below. The following content is only implementation details provided for easy understanding and is not necessary for implementing this solution.

[0027] When the fan is in working state, it has a directional working state mode and a uniform speed swing working state mode. The following is a specific description of the fan control methods in different working modes:

[0028] When the fan is in directional working mode, Figure 1 As shown, the fan control method includes the following steps:

[0029] Step 101 , when the fan is in a directional working state, detecting whether a target object is recognized within the wide-area viewing angle of a camera device in the current direction of the working device.

[0030] Specifically, when the fan is in a directional working state, the fan will blow air in a fixed direction, and the wind speed will remain at a set fixed value. At this time, the wide-area viewing angle range captured by the camera device will include the fan's air supply angle range, where the wide-area viewing angle range is the monitorable range of the camera device, and the air supply angle range is the fan's air blowing coverage range. Figure 2 As shown, the wide-area viewing angle range α captured by the camera device completely covers the air supply angle range β of the fan. By using the image captured in front of the fan, it can be determined whether there is an object that needs air supply in the direction where the fan is blowing, for example, whether there is a user or equipment and objects that need air supply, etc. The object that needs air supply is the target object mentioned in this embodiment.

[0031] After the camera device takes an image, the processor identifies the objects in the image. After determining that there are objects in the image that meet the corresponding shape, size and other characteristics, it is determined that the target object is identified within the wide-area viewing angle of the camera device. Conversely, if there are no objects in the image that meet the corresponding shape, size and other characteristics, it is determined that the target object is not identified within the wide-area viewing angle of the camera device.

[0032] Step 102: If the target object is identified, the working device is controlled to turn to the direction where the target object is located.

[0033] Specifically, since the wide viewing angle range α captured by the camera device completely covers the air supply angle range β of the fan, there is a situation where the target object is identified but the target object is not within the air supply angle range of the fan. In order to ensure that the target object can be within the air supply angle range, it is necessary to control the steering of the working device to ensure that the target object can be within the air supply angle range.

[0034] In order to ensure the blowing effect on the target object, the blowing direction of the working device can also be adjusted to an angle facing the target object, that is, the target object is on the extension line of the axis of rotation of the fan blade.

[0035] In the process of controlling the steering of the working device, the camera device can always capture images of the position in front of the working device as the working device rotates. The steering of the working device can be continuously corrected based on the images captured by the camera device until the working device is turned to the direction where the target object is located.

[0036] Step 103: If the target object is included in the air supply angle range of the working device during the turning process, the working device is controlled to stop rotating and keep supplying air.

[0037] Specifically, the rule for determining whether the target object is included in the air supply angle range of the working device can be to determine whether the target object is on the extension line of the axis of rotation of the fan blade through the image captured by the camera device, or to determine whether the target object has entered the air supply angle range through the image. Different rules can be selected according to actual needs. If it is necessary to ensure the air supply effect on the target object, the target object can be adjusted to be near the extension line of the axis of rotation of the fan blade to control the steering of the working device. If it is necessary to minimize the adjustment of the blowing direction of the working device, the fan steering control rule can be selected as the target object just entering the air supply angle range.

[0038] In addition, the method of determining the position of the target object relative to the working device through the captured image is as follows: based on the position of the camera device relative to the working device, the positional relationship between the air supply angle range of the working device and the image captured by the camera device is determined. For example, when the camera device is set on the front cover of the fan and is on the axis of rotation of the fan blades, if the target object is on the mid-perpendicular line of the captured image, it is determined that the target object is on the extension line of the axis of rotation of the fan blades, and so on.

[0039] Step 104: If the target object does not enter the air supply angle range of the working device during the turning process, the working device is controlled to reset and stop supplying air.

[0040] Step 105, if the target object is not identified within the wide-area viewing angle of the camera device in the current direction of the working device within the first preset time, the working device is controlled to rotate within the maximum head swing angle range, and continuously identify whether the target object is included in the wide-area viewing angle of the camera device during the rotation of the working device.

[0041] Specifically, when the fan is in a directional working state, the target object is not identified within the wide-area viewing angle of the camera device within the first preset time, indicating that the fan has not provided effective blowing for a sustained period of time. At this time, it is necessary to consider whether the fan's blowing effect needs to be continuously provided in the current scene.

[0042] By controlling the working device to rotate within the maximum swing angle range, and then using the camera device to continuously collect whether there is a target object within the maximum swing angle range, it is determined whether there is a target object that needs to provide a blowing effect in the current scene. If there is, the blowing direction can be automatically adjusted by controlling the steering of the working device to provide a blowing effect for the target object. If there is no fan, it means that the fan does not need to work in the current scene and the energy-saving mode can be automatically entered.

[0043] Step 106: If a target object is identified during the rotation of the working device, the working device is controlled to turn in the direction of the target object.

[0044] Specifically, if a target object is identified during the turning process, the working device can be controlled to turn toward the target object according to step 103 so that the target object is within the air supply angle range of the working device.

[0045] Step 107: If the target object is not identified within the maximum swing range of the working device, the working device is controlled to reset and stop supplying air.

[0046] Specifically, if the fan is not needed in the current scenario, the working device is controlled to reset (the working device is in the middle state position of the maximum swing angle range) and the air supply is stopped. Controlling the working device to reset is conducive to controlling the fan direction after the fan resumes working, and the middle state position can be quickly adjusted to the maximum swing position on both sides.

[0047] In an embodiment of the present invention, if the number of target objects recognized within the wide-area viewing angle of the camera device is greater than one, the shortest straight-line distance between each target object and the working device is calculated; the direction of the target object with the smallest shortest straight-line distance is selected as the target direction of the working device blowing air, and the working device is controlled to turn to the target direction. In the case where there are multiple target objects in front of the fan, a suitable and fixed single object is selected to adjust the blowing direction of the fan, so as to avoid the influence of multiple target objects on the control of the fan, which is conducive to improving the accuracy of fan control.

[0048] The shortest straight-line distance between the target object and the working device is the shortest distance between the working device and the target object. The shortest straight-line distance can be determined based on the depth information in the captured image, or calculated based on the size of the target object in the image, the actual size of the target object, the focal length of the camera, and other parameters.

[0049] If the target object with the shortest straight-line distance is outside the air supply angle range under the current direction of the working device, the shortest straight-line distance between the target object within the wide-area viewing angle of the camera device under the current direction of the working device and the working device is recalculated, and the target direction of the air blowing of the working device is re-determined based on the recalculated shortest straight-line distances. After the target object leaves the air supply angle range, if there are still other target objects within the current air supply angle range, the fan does not need to be readjusted, reducing the number of adjustments to the fan direction. If there is no target object within the air supply angle range, but there is a target object within the wide-area viewing angle of the camera device under the current direction of the working device, then the working device can be adjusted to a suitable blowing position with the minimum rotation angle according to the position of the target object, and the fan can also be quickly adjusted to a suitable blowing position.

[0050] In addition, if the target object just leaves the air supply angle range under the current orientation of the working device, the working device can also be controlled to track the orientation of the target object and automatically swing its head, that is, the working device can be controlled to turn so that the target object is always within the air supply angle range, until the working device rotates to the maximum swing angle and can no longer track the target object, then a suitable target object can be reselected and adjusted to a suitable blowing angle. This fan control method can be applied to continuous air supply to key objects, which is beneficial for targeted blowing of specific objects when there are multiple target objects in the scene.

[0051] If the number of target objects recognized within the wide-area viewing angle of the camera device is greater than one, the blowing direction of the fan can also be determined based on the positions of the multiple target objects in the image, and the position of the target object close to the center of the image is selected as the target direction of the fan blowing, and the fan can continue to track the position of the target object to blow until the target object is out of the maximum swing angle of the fan. Alternatively, the blowing direction is determined based on the change in the number of target objects in the image, so that the number of target objects in the image recognized in the blowing direction is the largest, ensuring that the blowing utilization rate of the fan is the highest at this time.

[0052] When the fan is in the uniform speed swing working mode, Figure 3 As shown, the fan control method includes the following steps:

[0053] Step 301, when the fan is in a uniform swinging working state, if the target object is not recognized within the wide-area viewing angle of the camera device within a second preset time, the working device is controlled to reset and be in a standby state.

[0054] Specifically, when the fan is in a uniform swinging state, it means that the user wants the fan to blow air continuously in a larger range. At this time, the fan usually does not change its own working mode. In order to avoid the ineffective operation of the fan at this time, the camera device will be used to continuously detect whether there is a target object within the fan swinging range. If the target object is not detected within a certain period of time, the working device is directly controlled to reset and enter the standby state. In the standby state, the fan will not supply air, and the working device will not be controlled to rotate.

[0055] Step 302: after the fan is in the standby state, if it is detected that there is a target object within the wide-area viewing angle of the camera device, the fan is restored to the uniform-speed swinging working state.

[0056] Specifically, when the fan is in standby mode, the camera device will still collect images within the wide-area viewing angle according to certain rules, and determine whether a target object enters the wide-area viewing angle. For example, images can be collected at a fixed period, or images can be collected continuously. If the target object is recognized in the image, the fan's uniform head swing working state is restored.

[0057] In addition, the recognition function of the camera device for the target object can be controlled by voice. A microphone is set on the fan to collect the user's voice instructions. When the preset instructions are recognized, the camera device can be triggered to recognize the fan in any working state. If the camera device detects a specific gesture of the user during the recognition process, it will trigger the relevant action corresponding to the gesture, such as triggering the control of the fan's direction, switching the target object the fan is facing to a new target object, etc.

[0058] In addition, during the operation of the fan, in addition to identifying the target according to the orientation of the working device, the camera device can also trigger all-round identification detection according to a fixed period. That is, under a fixed period, the working device is triggered to rotate within the maximum swing angle range, driving the camera device to perform a target identification within the maximum angle range. This all-round target identification method can coordinate the overall situation and formulate a suitable fan control strategy based on the overall situation in the scene.

[0059] In addition, in addition to controlling the direction of the fan, the wind speed can also be adjusted. After identifying the target object, the preset wind speed can be adjusted according to the actual distance between the target object and the fan, and the corresponding relationship between the preset wind speed and distance. For example, if the distance between the target object and the fan is greater than the optimal blowing distance under the current wind speed, the wind speed of the fan can be increased to ensure a better experience for the target object. In the process of adjusting the wind speed, it is necessary to ensure that the adjusted wind speed is not lower than the preset wind speed when the fan is turned on, to avoid the wind speed being too low to affect the blowing effect.

[0060] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.

In addition, a stepper motor 23 in the actuating module drives the driven wheel 21 through a driving wheel 24 to realize rotation control of the turntable 21, thereby driving the working device to reciprocate around the axis of the turntable center axis 25.

The camera device 3 is arranged on the working device front cover 11 and always rotates at the same angle as the working device. The camera device can usually be arranged on the symmetry axis of the working device front cover 11, or at the center position, to facilitate determination of the relative position relationship between the camera device shooting picture and the fan blowing range.
