Description

Technical Field

[0001] This invention relates to the field of fan technology, specifically to a fan control method, a fan using the fan control method, and a computer-readable storage medium using the fan control method. Background Technology

[0002] Currently, most people use fans at a fixed height or only oscillate left and right to blow air. If they want to blow air to different positions, they need to manually adjust the height of the fan head to adjust the airflow height, which makes it impossible for users to enjoy the most suitable airflow at all times.

[0003] An existing fan can automatically adjust its height and oscillate left and right, delivering airflow in upward, downward, left, and right directions. It adjusts the airflow direction based on the relative position of the target air-receiving area and the original air-delivery area in the image, ensuring the suitable area for airflow is within the fan's delivery range. However, this fan requires manual adjustment, which is inconvenient. Furthermore, the airflow is directed towards the body, potentially causing discomfort. For example, if a user holds the fan very close to their body for an extended period, the side exposed to the airflow evaporates sweat quickly, significantly lowering the skin temperature. The side not exposed to the airflow evaporates sweat more slowly, resulting in a relatively higher skin temperature and dilated blood vessels. This imbalance in blood circulation and sweat excretion can lead to headaches, dizziness, and general malaise, and in severe cases, even stroke. Therefore, direct exposure to drafts can have a significant impact on individuals with weakened immune systems.

[0004] Therefore, the fan control method needs to be further optimized. Summary of the Invention

[0005] The primary objective of this invention is to provide a fan control method that improves the comfort and health benefits of airflow to the human body.

[0006] The second objective of this invention is to provide a fan that improves the comfort and health benefits of blowing air onto the human body.

[0007] A third objective of this invention is to provide a computer-readable storage medium that improves the comfort and health benefits of human body ventilation.

[0008] To achieve the first objective mentioned above, the fan control method provided by the present invention includes: when confirming that a preset healthy blowing mode has been entered, adjusting the distance between the fan and the human body to be within a preset distance range; acquiring human body contour information in real time, and determining the blowing path of the fan along the human body contour based on the human body contour information; and controlling the fan to blow along the blowing path.

[0009] As can be seen from the above solution, when the fan control method of the present invention confirms that the preset healthy blowing mode has been entered, it adjusts the distance between the fan and the human body to a suitable blowing distance and controls the fan to blow along the contour of the human body. This facilitates automatic adjustment of the blowing distance and avoids direct blowing, thereby improving the comfort and health of the human body during blowing.

[0010] In a further proposed solution, the steps for confirming entry into the preset healthy airflow mode include: obtaining the number of people within the fan's airflow range; and when the number of people is determined to be one, then entering the preset healthy airflow mode.

[0011] Therefore, the preset healthy blow-drying mode is only confirmed when the number of people is determined to be one, so as to avoid the blow-drying position being too many when there are too many people, which would not meet the user's blow-drying needs.

[0012] In a further solution, the step of obtaining the number of people within the fan's blowing range includes: obtaining the number of people a preset number of times within a preset time period; when the number of people obtained in the preset number of times is equal, the number of people is confirmed.

[0013] Therefore, in order to avoid personnel movement, the number of personnel is collected a preset number of times within a preset time period, thereby improving the detection accuracy.

[0014] In a further proposed solution, the step of adjusting the distance between the fan and the human body to be within a preset distance range includes: obtaining the distance between the fan and the human body; if the distance between the fan and the human body is less than the lower limit of the preset distance range, then increasing the distance between the fan and the human body; if the distance between the fan and the human body is within the preset distance range, then keeping the fan in its current position; if the distance between the fan and the human body is greater than the upper limit of the preset distance range, then decreasing the distance between the fan and the human body.

[0015] Therefore, by measuring the distance between the fan and the human body, the fan's blowing distance can be controlled, thus improving the comfort of the airflow.

[0016] In a further embodiment, when the distance between the fan and the human body is less than the lower limit of a preset distance range, the method further includes: determining whether the space where the fan is located satisfies the requirement to adjust the distance between the fan and the human body to be within the preset distance range; if not, moving the fan to the position corresponding to the maximum distance from the human body.

[0017] Therefore, when the distance between the fan and the human body is less than the preset distance, it is necessary to first determine whether the space where the fan is located meets the requirement of adjusting the distance between the fan and the human body to be within the preset distance range. If the fan cannot meet the preset distance range when moved to the maximum distance from the human body, then the fan should be moved to the position corresponding to the maximum distance from the human body.

[0018] In a further solution, the step of determining the airflow path of the fan along the human body contour based on the human body contour information includes: determining whether the center of the fan's airflow is on the human body contour path; if not, adjusting the airflow path of the center of the airflow.

[0019] Therefore, when determining the airflow path of the fan along the human body contour based on the human body contour information, if the center of the fan's airflow is outside the human body contour path, the airflow path of the center of the airflow will be adjusted, thereby dynamically adjusting the airflow position and improving the user's comfort.

[0020] In a further embodiment, the steps for controlling the fan to blow air along the airflow path include: adjusting the fan's airflow volume according to the distance between the fan and the human body.

[0021] Therefore, it can be seen that, under the same air volume, the farther the fan is from the human body, the less wind force the human body feels. Therefore, adjusting the air volume of the fan according to the distance between the fan and the human body can reasonably control the air volume of the fan and improve the user's comfort.

[0022] In a further embodiment, the steps for controlling the fan to blow air along the airflow path include: adjusting the fan's airflow volume according to the body temperature.

[0023] Therefore, adjusting the fan's airflow according to body temperature can improve user comfort by adjusting the airflow according to the user's needs.

[0024] In a further embodiment, after controlling the fan to blow air along the airflow path, the method further includes: determining whether the duration of the airflow state exceeds a preset duration; if so, controlling the fan to enter sleep mode, or controlling the fan to enter a preset intermittent working mode, or controlling the fan to enter a preset indoor airflow adjustment mode.

[0025] Therefore, to prevent users from blowing air for too long, when the duration of blowing air exceeds the preset time, the fan will be controlled to enter sleep mode, or the fan will be controlled to enter the preset intermittent working mode, or the fan will be controlled to enter the preset indoor airflow adjustment mode, thereby improving the health of users when blowing air.

[0026] To achieve the second objective of the present invention, the present invention provides a fan including a processor and a memory, the memory storing a computer program, which, when executed by the processor, implements the steps of the above-described fan control method.

[0027] To achieve the third objective of the present invention, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a controller, implements the steps of the fan control method described above.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0037] The fan control method of the present invention is an application program used in a fan to control the fan's airflow and achieve a healthy airflow mode. Preferably, the fan has an airflow control device for controlling the fan's airflow in the upward, downward, left, and right directions, and a drive mechanism for moving the fan's position. In the fan of this embodiment, as... Figure 1 As shown, the blower control device includes a base 1, a motion bracket 2, and a blower assembly 3. The motion bracket 2 is mounted on the base 1, and the blower assembly 3 is mounted on the motion bracket 2. A motor (not shown) is installed inside the base 1 to control the rotation of the motion bracket 2 along the circumference of the base 1, thereby driving the blower assembly 3 to rotate to the left or right. The motion bracket 2 is used to adjust the height of the blower assembly 3 and control its upward or downward swing. See [reference needed]. Figure 2 and Figure 3The motion support 2 includes a first support 21, a second support 22, and a third support 23. The first end of the first support 21 is connected to the base 1, the first end of the second support 22 is connected to the second end of the first support 21, the first end of the third support 23 is connected to the second end of the second support 22, and the second end of the third support 23 is connected to the fan assembly 3. All connections between the first support 21, the second support 22, and the third support 23 are made via motors (not shown). The first support 21 and the second support 22 are used to adjust the height of the fan assembly 3, and the third support 23 is used to control the upward or downward swing of the fan assembly 3. The connection method of the first support 21, the second support 22, and the third support 23 adopts a known method, such as the connection method of a multi-axis robotic arm, which will not be described in detail here.

[0038] In this embodiment, the drive mechanism includes a pulley 4 installed at the bottom of the base 1, which can drive the fan to the position where it needs to be parked.

[0039] In addition, an infrared sensor (not shown) is also provided on the fan assembly 3 for thermal imaging and distance measurement. The infrared sensor is installed at the air outlet of the fan assembly 3. In this embodiment, the thermal imaging of the infrared sensor is used to identify human information, and the distance measurement function is used to measure the distance between the fan and the human body and the size of the space where the fan is located. The thermal imaging and distance measurement functions of the infrared sensor are technologies known to those skilled in the art and will not be described in detail here.

[0040] In another embodiment, human body information can also be obtained through video recognition, which is a technique known to those skilled in the art and will not be described in detail here.

[0041] Example of fan control method:

[0042] like Figure 4 As shown, in this embodiment, when the fan control method is working, it first executes step S1 to determine whether to enter the preset healthy airflow mode. To avoid the fan blowing directly on the user and affecting their health, it is necessary to confirm entry into the preset healthy airflow mode. Entering the preset healthy airflow mode can be done via button commands or by setting certain conditions.

[0043] In this embodiment, see Figure 5 When determining whether to enter the preset healthy airflow mode, step S11 is first executed to obtain the number of people within the fan's airflow range. The fan's airflow range is determined based on the fan's rotatable directional range. The number of people can be determined by infrared detection, which is a technique known to those skilled in the art and will not be elaborated upon here.

[0044] In this embodiment, the step of obtaining the number of people within the fan's blowing range includes: obtaining the number of people a preset number of times within a preset time period; when the number of people obtained the preset number of times is equal, the number of people is confirmed. The preset time period and preset number of times can be preset based on experimental data, for example, a preset time period of 5 seconds and a preset number of times of measurement. Obtaining the number of people a preset number of times within the preset time period avoids changes in the number of people due to movement, thereby improving detection accuracy.

[0045] After obtaining the number of people within the fan's airflow range, step S12 is executed to determine if the number of people is one. If the number of people is confirmed to be one, step S13 is executed to enter the preset healthy airflow mode. To avoid excessive airflow positions when there are too many people, which may not meet the user's airflow needs, the preset healthy airflow mode is only entered when the number of people is confirmed to be one. If it is confirmed that there are more than one person, step S14 is executed to enter the normal airflow mode. The normal airflow mode can be a user-defined mode, such as direct airflow, left-right oscillation airflow, etc.

[0046] If the preset healthy airflow mode is not confirmed during step S1, continue with step S1 for continuous monitoring. Once the preset healthy airflow mode is confirmed, proceed to step S2 to adjust the distance between the fan and the body to a preset range. This preset range can be pre-set based on experimental data. After entering the preset healthy airflow mode, to ensure the fan and body are at a suitable airflow distance, the distance needs to be adjusted to the preset range.

[0047] In this embodiment, the step of adjusting the distance between the fan and the human body to be within a preset distance range includes: obtaining the distance between the fan and the human body; if the distance between the fan and the human body is less than the lower limit of the preset distance range, increasing the distance between the fan and the human body; if the distance between the fan and the human body is within the preset distance range, keeping the fan in its current position; and if the distance between the fan and the human body is greater than the upper limit of the preset distance range, decreasing the distance between the fan and the human body. By obtaining the distance between the fan and the human body, the fan's blowing distance can be controlled, improving the comfort of the airflow.

[0048] In this embodiment, see Figure 6 If the distance between the fan and the human body is less than the lower limit of a preset distance range, step S21 is executed to determine whether the space where the fan is located satisfies the requirement to adjust the distance between the fan and the human body to be within the preset distance range. Before increasing the distance between the fan and the human body, it is necessary to determine whether there is enough space in the space where the fan is located to move the fan. The location of the fan and the size information of the space where the fan is located can be confirmed by obtaining a spatial map function. This is a technique known to those skilled in the art and will not be described in detail here.

[0049] If the space where the fan is located does not meet the requirement of adjusting the distance between the fan and the person to be within the preset distance range, then step S22 is executed to move the fan to the position corresponding to the maximum distance from the person. If moving the fan to the maximum distance from the person does not meet the preset distance, then the fan is moved to the position corresponding to the maximum distance from the person. For example, see... Figure 7 , Figure 7 The upper half of the diagram shows a person 20 sitting in front of a table 30. When the fan 10 is at position A, the distance between the fan 10 and the person 20 is less than the lower limit of a preset distance range. Therefore, the distance between the fan 10 and the person 20 needs to be increased. Assuming that moving the fan 10 to position B represents the maximum distance between the fan 10 and the person 20 within its current space, and this maximum distance is less than the lower limit of the preset distance range, then the fan 10 will be moved to position B, corresponding to the maximum distance from the person 20.

[0050] If the space where the fan is located satisfies the requirement that the distance between the fan and the person be within a preset distance range, then step S23 is executed to adjust the distance between the fan and the person to within the preset distance range. If the space where the fan is located satisfies the requirement that the distance between the fan and the person be within the preset distance range, then the distance between the fan and the person can be directly increased. For example, see... Figure 7 , Figure 7 The lower half of the diagram shows a person 50 sleeping on a bed 60. When the fan 40 is in position C, the distance between the fan 40 and the person 50 is less than a preset distance range. Therefore, it is necessary to increase the distance between the fan 40 and the person 50. At this point, if it is confirmed that the space in which the fan 40 is located satisfies the requirement to adjust the distance between the fan 40 and the person 50 to be within the preset distance range, then the fan 40 can be moved directly. For example, when the fan 40 is moved to position D, the distance between the fan 40 and the person 50 is within the preset distance range.

[0051] After adjusting the distance between the fan and the human body to a preset range, step S3 is executed to acquire human body contour information in real time. Based on this information, the airflow path for the fan to blow air along the human body contour is determined. To facilitate real-time adjustment of the airflow path, it is necessary to acquire human body contour information in real time and adjust the airflow path accordingly to improve comfort. Human body contour information can be obtained through infrared sensor detection.

[0052] In this embodiment, see Figure 8When determining the airflow path of the fan along the human body contour based on the human body contour information, step S31 is first executed to determine whether the fan's airflow center is within the human body contour path. The fan's airflow center refers to the center of the area covered by the fan's airflow near the human body. To prevent the airflow center from deviating due to human body movement, it is necessary to determine in real time whether the fan's airflow center is within the human body contour path. The human body contour path can be determined after obtaining the human body contour information; for example, the fan's airflow center blows air circumferentially around the outside of the human body contour. Of course, since the area covered when the fan's airflow reaches the vicinity of the human body is relatively large, the fan's airflow center can be located at a preset distance away from the human body contour line, thereby further reducing the probability of direct airflow.

[0053] If the fan's airflow center is not on the human body contour path, then step S32 is executed to adjust the airflow path of the airflow center. If the fan's airflow center is not on the human body contour path, it means that the human body contour has shifted and the airflow path needs to be readjusted. Therefore, the fan is controlled to adjust the airflow center.

[0054] If the fan's airflow center is within the human body contour path, then step S33 is executed to maintain the current airflow path. If the fan's airflow center is within the human body contour path, it means that the human body contour has not shifted, and the current airflow path can continue to be maintained.

[0055] After confirming the airflow path of the fan along the contour of the human body, proceed to step S4 to control the fan to blow air along the airflow path. After confirming the airflow path, the fan can be controlled to blow air along the airflow path using the airflow control device.

[0056] In this embodiment, the step of controlling the fan to blow air along the airflow path includes: adjusting the fan's airflow volume according to the distance between the fan and the user. At the same airflow volume, the farther the fan is from the user, the weaker the wind force felt by the user. Therefore, adjusting the fan's airflow volume according to the distance between the fan and the user allows for reasonable control of the fan's airflow volume, improving user comfort. The airflow volume can be adjusted by changing the fan speed.

[0057] In this embodiment, the step of controlling the fan to blow air along the airflow path includes adjusting the fan's airflow volume according to human body temperature. Adjusting the fan's airflow volume according to human body temperature allows for adjustment of the airflow volume according to the user's needs, improving user comfort. For example, by detecting human body temperature information using an infrared sensor, the airflow volume is increased when the fan's airflow center moves to the side of the human body with a higher temperature, and decreased when the fan's airflow center moves to the side of the human body with a lower temperature. Alternatively, the airflow volume can be controlled according to human body temperature.

[0058] After controlling the fan to blow air along the airflow path, step S5 is executed to determine whether the duration of the airflow state exceeds a preset duration. The preset duration can be set based on experimental data, for example, a preset duration of 1 hour. To prevent users from experiencing excessive airflow and affecting their health, it is necessary to control the user's airflow duration.

[0059] If the duration of the fan blowing mode does not exceed the preset duration, proceed to step S4 to continuously blow air onto the user. If the duration of the fan blowing mode exceeds the preset duration, proceed to step S6 to control the fan to enter sleep mode, or control the fan to enter a preset intermittent working mode, or control the fan to enter a preset indoor airflow adjustment mode. By controlling the fan to enter sleep mode, or control the fan to enter a preset intermittent working mode, or control the fan to enter a preset indoor airflow adjustment mode when the duration of the fan blowing mode exceeds the preset duration, the system avoids prolonged exposure to airflow and improves the user's health during fan blowing.

[0060] As can be seen from the above, when the fan control method of the present invention confirms that the preset healthy blowing mode has been entered, it adjusts the distance between the fan and the human body to a suitable distance and controls the fan to blow air along the contour of the human body. This facilitates automatic adjustment of the blowing distance and avoids direct blowing, thereby improving the comfort and health of the human body during blowing.
