Description

Technical Field

[0001] This invention relates to the field of energy-saving fan equipment technology, and in particular to a power outage-resumption fan device and its control method, control device, and storage medium. Background Technology

[0002] Traditional fan units rely on the power grid for power. However, in some regions (such as Africa and South Asia) or in certain application scenarios, the power grid supply system is often accompanied by voltage fluctuations, line faults, and sudden power outages, which will cause the fan unit to stop. In hot environments, users lose their source of cooling, which seriously affects their activities. Some users will install energy storage modules in the fan unit to keep it running. However, since the energy stored in the energy storage module is limited, it is not enough to support the user's use at will. Otherwise, the energy will be depleted quickly and cannot meet the user's basic heat dissipation needs. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a power outage-resumption fan device and control method, control device, and storage medium, which maintains airflow supply and improves airflow utilization during power fluctuations or even power outages, rationally utilizes energy storage, reduces power consumption, and extends the airflow duration.

[0004] According to a first aspect of the present invention, a power-off fan device includes: a sensing terminal, comprising a wind speed sensor, a main control module, and a sensing coupling component, wherein the wind speed sensor is used to detect the airflow speed at the location of the sensing terminal; an air outlet module, comprising a base, an air outlet module, a control module, a sensing receiver, a voltage detection module, a power supply switching module, and an energy storage module, wherein the sensing receiver is used to sense the interaction direction of the sensing coupling component, the control module is wirelessly connected to the main control module, the air outlet module is rotatably mounted on the base to change the air outlet direction, the voltage detection module is used to connect to a power supply to detect the power supply voltage, the power supply switching module includes a power supply terminal, an energy storage terminal, and an output terminal, wherein the power supply terminal of the power supply switching module is used to connect to the power supply, the energy storage terminal of the power supply switching module is connected to the energy storage module, and the output terminal of the power supply switching module is connected to the air outlet module, the power supply switching module has at least a first operating state and a second operating state that can be switched between each other, wherein in the first operating state, the power supply terminal and the energy storage terminal of the power supply switching module are connected, and the power supply terminal and the output terminal of the power supply switching module are connected. In the second working state, the energy storage terminal and the output terminal of the power supply switching module are connected. The control module is connected to the air outlet module, the sensing receiver, the voltage detection module, and the power supply switching module to execute the regulation method. The regulation method includes controlling the power supply switching module to be in the first working state and controlling the air outlet module to run according to the set air outlet speed and the set air outlet direction. When the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold, the air supply regulation step is executed. The air supply regulation step includes: determining the air detection direction range according to the interaction direction, which is used to limit the range of the air outlet direction of the air outlet module; controlling the air outlet module to rotate to traverse the air detection position points of different air outlet directions within the air detection direction range, and acquiring the airflow speed fed back by the wind speed sensor at each air detection position point; selecting the air outlet direction corresponding to the air detection position point with the largest airflow speed to set as the air supply direction, and controlling the air outlet module to rotate to the air supply direction; when the power supply voltage is zero, controlling the power supply switching module to switch to the second working state and controlling the air outlet module to run the blowing according to the regulated air outlet speed.

[0005] The power-off fan device according to the embodiments of the present invention has at least the following beneficial effects:

[0006] This invention relates to a power outage-resumption fan device. The user places the sensing terminal nearby. When power is normal, the air outlet module can output air according to the user-set airflow speed and direction. The voltage detection module samples the power supply voltage. When the voltage fluctuation reaches a threshold, it indicates a potential power outage. At this point, a resuming airflow control step is executed. The interaction direction of the sensing receiver and sensing device is used to roughly determine the user's direction relative to the air outlet module. This interaction direction defines the airflow detection direction range. The air outlet module then traverses different airflow detection points within this range. The airflow speed is determined by the wind speed sensor on the sensing terminal to determine which detection point the air outlet module rotates to for airflow output. The airflow near the user is also considered. The system operates at a relatively high speed, serving as the airflow direction. It controls the air outlet module to rotate to this direction and outputs air at the user-defined speed. If a power outage occurs, the power supply voltage drops to zero, and the power switching module switches to a second operating state, powered by the energy storage module. The air outlet module then operates at the regulated speed. While the regulated speed is typically lower than the set speed, the air outlet module, having rotated to the airflow direction, maintains a reasonable airflow for the user by combining the airflow from the regulated speed with the ambient airflow, ensuring basic heat dissipation. This design maintains airflow supply and improves airflow utilization during power fluctuations or even outages, effectively utilizing energy storage to reduce energy consumption and extend the airflow duration.

[0008] According to some embodiments of the present invention, the step of determining the air detection direction range based on the interaction direction includes: determining the air detection direction range in a fan-shaped area centered on the interaction direction and at a preset angle.

[0009] According to some embodiments of the present invention, the step of determining the air detection direction range based on the interaction direction includes: deriving the equilibrium direction based on the center between the interaction direction and the set air outlet direction; and determining the air detection direction range with the equilibrium direction as the center and a fan-shaped area with a preset angle.

[0010] According to some embodiments of the present invention, the process of controlling the air outlet module to rotate to traverse the air inspection position points of different air outlet directions within the air inspection direction range, and correspondingly acquiring the airflow velocity fed back by the wind speed sensor at each air inspection position point, includes: dividing the air inspection direction range into a preset number of directional intervals, with the nodes at the beginning and end of the air inspection direction range and the nodes between adjacent directional intervals serving as air inspection position points; rotating the air outlet module to the air inspection position point at the beginning of the air inspection direction range, starting from the air inspection position point at the beginning of the air inspection direction range, controlling the air outlet module to rotate towards the air inspection position point at the end of the air inspection direction range, and rotating to the next air inspection position point after staying at each air inspection position point for the required air inspection time, wherein the air outlet velocity of the air outlet module is the same at each air inspection position point; and acquiring the airflow velocity fed back by the wind speed sensor while staying at each air inspection position point.

[0011] According to some embodiments of the present invention, the process of obtaining the airflow velocity fed back by the wind speed sensor when staying at each air detection location includes: obtaining N airflow velocity values ​​at each air detection location at a preset frequency; calculating the average value of the N airflow velocity values ​​as an airflow reference value; and selecting the air outlet direction corresponding to the air detection location with the largest airflow velocity to set as the continuing airflow direction includes: selecting the maximum value from the airflow reference values ​​of each air detection location, and setting the air outlet direction corresponding to the maximum value as the continuing airflow direction.

[0012] According to some embodiments of the present invention, the air outlet module further includes a power detection module, which is connected to the energy storage module to detect the energy storage power value; the process of controlling the air outlet module to operate the blowing according to the controlled air outlet speed includes: setting the controlled air outlet speed according to the change of the energy storage power value, wherein the smaller the energy storage power value, the smaller the controlled air outlet speed.

[0013] According to the second aspect of the present invention, the control method is applied to the power outage fan device disclosed in any of the above embodiments, and the control module executes the control method to control the operation of the air outlet module.

[0014] The control method according to embodiments of the present invention has at least the following beneficial effects:

[0015] The control method of the present invention is applied to the power outage-resumption fan device disclosed in any of the above embodiments. When the power supply fluctuates or even fails, it maintains the airflow supply and improves the airflow utilization rate, makes reasonable use of energy storage, reduces power consumption, and extends the airflow duration.

[0031] like Figures 1 to 4 As shown, the power outage and resuming fan device according to a first aspect embodiment of the present invention includes a sensing terminal 100 and an air outlet module 200. The sensing terminal 100 includes a wind speed sensor 110, a main control module 120, and a sensing coupling component 130. The wind speed sensor 110 is used to detect the airflow speed at the location of the sensing terminal 100. The air outlet module 200 includes a base, an air outlet module 210, a control module 220, a sensing receiver 230, a voltage detection module 240, a power supply switching module 250, and an energy storage module 260. The sensing receiver 230 is used to sense the interaction direction of the sensing coupling component 130. The control module 220 is wirelessly connected to the main control module 120. The air outlet module 210 is rotatably mounted on the base to change the air outlet direction. The voltage detection module 240 is used to connect to the power supply to detect the power supply voltage. The power supply switching module 250 includes... The power supply switching module 250 has a power supply terminal, an energy storage terminal, and an output terminal. The power supply terminal of the power supply switching module 250 is connected to the power supply, the energy storage terminal of the power supply switching module 250 is connected to the energy storage module 260, and the output terminal of the power supply switching module 250 is connected to the air outlet module 210. The power supply switching module 250 has at least a first working state and a second working state that can be switched between each other. In the first working state, the power supply terminal and the energy storage terminal of the power supply switching module 250 are connected, and the power supply terminal and the output terminal of the power supply switching module 250 are connected. In the second working state, the energy storage terminal and the output terminal of the power supply switching module 250 are connected. The control module 220 is connected to the air outlet module 210, the sensing receiver 230, the voltage detection module 240, and the power supply switching module 250 respectively to execute the control method.

[0032] The sensing terminal 100 includes a movable housing, which can be table-shaped for placement on a desktop or long-handled for user grip, depending on the manufacturer's specific needs. The main control module 120 can be a processor such as an MCU or CPU and its associated circuitry, and can be housed within the housing. The sensing component 130 can be a radar emitting chip or an ultrasonic emitting chip, and can be inserted into the housing. The wind speed sensor 110 can be a thermal anemometer chip, a rotor-type anemometer, etc., and is exposed within the housing to detect airflow speed. The housing can also house a control module, which can be buttons, a touchscreen, etc., on the housing. Users can input settings such as airflow speed and direction through the control module to wirelessly control the airflow module 210. The sensing terminal 100 can contain a battery that powers the control module, main control module 120, wind speed sensor 110, and sensing component 130.

[0033] The air outlet module 200 can be a fan, air conditioner, etc. Taking a fan as an example, the base can be vertically installed on the ground or a table. The air outlet module 210 can include a housing, a fan, a motor, and blades. The fan and motor are both installed in the housing. The motor is connected to the base, thereby changing the air outlet direction. The fan is connected to the blades to drive the blades to rotate. It can be understood that the control module 220 can be a processor such as an MCU or CPU and its auxiliary circuits. The drive circuit in the control module 220 is connected to the motor and the fan respectively to drive the motor and the fan to run. The control module 220 can record the rotation position of the motor to determine the air outlet direction. The control module 220 can adjust the magnitude of the drive current output to the fan to control the fan speed, and change the air outlet speed by controlling the fan speed. The sensing receiver 230 can be a radar receiver chip or an ultrasonic receiver chip paired with the sensing mating component 130. The sensing receiver 230 analyzes the direction of the sensing mating component 130 based on the direction and intensity of the signal transmission to determine the interaction direction.

[0034] The voltage detection module 240 can be selected from a conventional resistive voltage divider circuit, and the energy storage module 260 can be selected from a conventional battery. Under normal use, the air outlet module 210, control module 220, and sensing receiver 230 can all be powered by the power supply. When the power supply is turned off, the energy storage module 260 supplies power to the air outlet module 210, control module 220, and sensing receiver 230.

[0035] The power supply switching module 250 can be selected from conventional charging and discharging circuits. In the first working state, the energy storage terminal and the output terminal of the power supply switching module 250 are disconnected. The power supply can be rectified and regulated by the charging and discharging circuit to adjust to a suitable voltage to power the air outlet module 210, the control module 220, and the sensing receiver 230, while also charging the energy storage module 260. In the second working state, the power supply terminal and the energy storage terminal of the power supply switching module 250 are disconnected, as are the output terminal of the power supply switching module 250. The energy storage module 260 supplies power to the air outlet module 210, the control module 220, and the sensing receiver 230 through the charging and discharging circuit.

[0036] In addition, the control module 220 and the main control module 120 can be wirelessly connected via communication protocols such as Bluetooth, radio frequency, infrared, and WiFi.

[0037] The control method includes controlling the power supply switching module to be in a first working state, and controlling the air outlet module to operate according to a set air outlet speed and a set air outlet direction. When the fluctuation amplitude of the power supply voltage reaches a fluctuation threshold, a follow-up airflow control step is executed, such as... Figure 4 As shown, the air supply regulation step includes:

[0038] S310. Determine the air detection direction range based on the interaction direction. The air detection direction range is used to limit the range of the air outlet direction of the air outlet module.

[0039] S320: Control the air outlet module to rotate to traverse the air outlet position points of different air outlet directions within the air inspection direction range, and obtain the airflow speed fed back by the wind speed sensor at each air inspection position point.

[0040] S330: Filter out the air outlet direction corresponding to the air detection position point with the maximum airflow velocity and set it as the air supply direction; control the air outlet module to rotate to the air supply direction.

[0041] S340. When the power supply voltage is zero, control the power supply switching module to switch to the second working state, and control the air outlet module to run the blowing according to the regulated air outlet speed.

[0042] Under normal use, the air outlet speed of the air outlet module 210 can be adjusted by stepless modulation or multi-level adjustment. The air outlet module 210 controls the motor to rotate to the corresponding direction according to the set air outlet direction, and then controls the fan to rotate and outlet air according to the set air outlet speed.

[0043] It is understandable that when a user uses the sensor terminal 100, the user places it next to them. Therefore, the airflow speed detected by the sensor terminal 100 is roughly the airflow speed at the user's location.

[0044] When the air outlet module 200 is placed in the environment, there is also natural airflow in the environment. Since the air outlet direction is set arbitrarily by the user, the air outlet module 210 outlets air according to the set air outlet direction. After the airflow mixes with the natural wind, it may not be able to make the airflow speed at the user's location reach a large value.

[0045] The voltage detection module 240 samples the power supply voltage. When the fluctuation range of the power supply voltage reaches the fluctuation threshold, it means that there may be a risk of power outage. The power supply can be selected as DC or three-phase AC according to the actual power consumption of the region. The fluctuation threshold can be set to 10-30V, or the fluctuation threshold can be set to ±10% of the local standard power supply voltage. At this time, the airflow control step is executed. The interaction direction of the sensing receiver 230 and the sensing cooperation component 130 is obtained to roughly determine the direction of the user relative to the air outlet module 200. The airflow direction range is determined by the interaction direction. Then, the air outlet module 200 traverses the airflow detection position points of different airflow directions within the airflow detection direction range. The airflow speed fed back by the wind speed sensor 110 on the sensing terminal 100 is used to determine which airflow detection position the air outlet module 200 rotates to to discharge air. The airflow speed near the user is relatively large, which is taken as the airflow direction. The air outlet module 210 is controlled to rotate to the airflow direction. Furthermore, the airflow is delivered according to the user-set airflow speed. If the power supply subsequently fails and the power supply voltage becomes zero, the power supply switching module 250 switches to the second working state, where the energy storage module 260 provides power and controls the airflow module 210 to operate at the regulated airflow speed. Generally, the regulated airflow speed is lower than the set airflow speed, which is set by the manufacturer based on the actual conditions of the area of ​​use, or by the user according to their own needs. Of course, the regulated airflow speed can be varied. The higher the initial value of the regulated airflow speed is set, the faster the energy consumption. In addition, since the airflow module 210 has been rotated and adjusted to the airflow direction, the airflow output by the airflow module 200 according to the regulated airflow speed, combined with the airflow in the environment, can maintain a reasonable airflow for the user, ensuring basic heat dissipation. This design maintains the airflow supply and improves the airflow utilization rate during power fluctuations or even power outages, rationally utilizes energy storage, reduces energy consumption, and extends the airflow duration.

[0046] It should be noted that before a power outage, if the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold, the air outlet module 210 is controlled to rotate and traverse each air detection point within the air detection direction range. A power outage may occur during this traversal. If a power outage occurs at this time, the energy storage module 260 provides power to continue the traversal of each air detection point within the air detection direction range. If the traversal of each air detection point within the air detection direction range is completed without a power outage, the air outlet module 210 can be controlled to rotate to the air supply direction and output air at a set airflow speed. This ensures that after a power outage, the air outlet module 210 does not need to perform other actions, thus avoiding wasting energy; only the airflow speed needs to be adjusted. If, after a period of fluctuation, there is no secondary fluctuation or power outage, it can be considered an occasional fluctuation. Therefore, in some embodiments of the present invention, the step of controlling the power supply switching module 250 to switch to the second working state when the power supply voltage is zero and controlling the air outlet module 210 to operate according to the adjusted airflow speed includes:

[0047] The recording delay time is triggered when the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold.

[0048] When the power supply voltage is zero, the power supply switching module 250 is switched to the second working state, and the air outlet module 210 is controlled to blow air according to the regulated air outlet speed.

[0049] When the delay time reaches the delay threshold, the air outlet module 210 is controlled to resume operation according to the set air outlet direction;

[0050] If, during the recording of the delay time, the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold again, the delay time will be reset to zero.

[0051] The delay threshold can be set to 60s, 80s, 120s, etc. The air outlet module 200 can be equipped with a timer. When the fluctuation of the power supply voltage reaches the fluctuation threshold, the delay time of the timer is reset to zero, and then the delay time is recorded again. If the power supply voltage is zero during this time, it means that the power supply is cut off. The power supply switching module 250 is controlled to switch to the second working state, and the air outlet module 210 operates according to the regulated air outlet speed. If the delay time reaches the delay threshold, it means that the fluctuation is just an occasional event, and the air supply regulation step is canceled. If the fluctuation occurs again, it means that the risk has not been eliminated, and the delay is restarted to prepare for possible power outages in the future.

[0052] In some embodiments of the present invention, such as Figure 2 As shown, the range of wind inspection directions determined based on the interaction direction includes:

[0053] The range α of the air detection direction is defined by a fan-shaped area centered on the interaction direction and at a preset angle.

[0054] The preset angle of the fan-shaped area can be set by the manufacturer and the user according to the actual situation. For example, it can be 60°, 80° or 120°. The air outlet module 210 can rotate within the air detection direction range to find a position point where the wind speed at the user's location can reach a relatively fast position as the air supply direction.

[0055] Considering that the initial airflow direction set by the user has some reference value, in some embodiments of the present invention, such as Figure 3 As shown, the range of wind inspection directions determined based on the interaction direction includes:

[0056] The equilibrium direction is determined by the center between the interaction direction and the set air outlet direction.

[0057] The range β of the air detection direction is determined by a fan-shaped area centered on the equilibrium direction and at a preset angle.

[0058] Taking into account the user's settings, the center between the interaction direction and the set airflow direction is first calculated as the equilibrium direction. Then, using the equilibrium direction as the center, a fan-shaped area with a preset angle is used to determine the airflow detection direction range. At this time, the determined airflow detection direction range can be compatible with the direction set by the user and the direction near the interaction direction, making it easy to find a location that meets the user's needs and allows the wind speed at the user's location to reach a relatively fast position as the continuing airflow direction.

[0059] In some embodiments of the present invention, the control air outlet module 210 rotates to traverse the air outlet position points of different air outlet directions within the air outlet direction range, and the airflow velocity fed back by the wind speed sensor 110 is obtained correspondingly at each air outlet position point, including:

[0060] The air inspection direction range is divided into a preset number of direction intervals on an average basis. The nodes at the beginning and end of the air inspection direction range and the nodes between adjacent direction intervals are used as air inspection location points.

[0061] Rotate the air outlet module 210 to the air inspection position at the beginning of the air inspection direction range. Starting from the air inspection position at the beginning of the air inspection direction range, control the air outlet module 210 to rotate toward the air inspection position at the end of the air inspection direction range. After staying at each air inspection position for the required time, rotate to the next air inspection position. The air outlet speed of the air outlet module 210 is the same at each air inspection position.

[0062] The wind speed is obtained from the wind speed sensor 110 when the device stays at each wind detection location.

[0063] Taking a 60° airflow detection direction range as an example, the span of the direction interval can be set to 5°, 10°, etc. The air outlet module 210 first rotates to the airflow detection position at the beginning of the airflow detection direction range, i.e., the 0° position. The air outlet module 210 stays at this position for the airflow detection time and maintains airflow. The airflow speed at each airflow detection position is the same. The airflow speed here can be a set airflow speed or an additional set airflow detection airflow speed, which is set by the manufacturer or the user. During the dwell time, the wind speed sensor 110 detects multiple airflow speeds and feeds them back to the control module 220. Each airflow detection position uses the same method to collect data, and finally determines the magnitude of the airflow speed at each airflow detection position.

[0064] Specifically, the airflow velocity fed back by the wind speed sensor 110 when staying at each wind detection location point includes:

[0065] At each air detection location, N airflow velocity values ​​are acquired at a preset frequency;

[0066] Calculate the average of N airflow velocity values ​​as the airflow reference value;

[0067] The process of selecting the air outlet direction corresponding to the air sensor location with the maximum airflow velocity and setting it as the continuing air direction includes:

[0068] The maximum value is selected from the airflow reference values ​​at each air inspection point, and the air outlet direction corresponding to the maximum value is set as the continuous airflow direction.

[0069] The preset frequency can be set by the manufacturer or user according to the actual situation. It can be understood that the period corresponding to the preset frequency can be set to 0.2s, 0.5s, etc., which means that one airflow velocity value is collected in each period. The air detection time can also be set by the manufacturer or user according to the actual situation. For example, if the air detection time is 2s and the period corresponding to the preset frequency is 0.2s, then 10 airflow velocity values ​​can be collected, that is, N=10. The average value of the 10 airflow velocity values ​​is calculated as the airflow reference value. It can be understood that there is natural airflow in the environment. Although the airflow in the environment is constantly changing, the impact of airflow changes is reduced by setting a certain air detection time. At the same time, it can also combine the outlet airflow with the natural airflow. The airflow velocity fed back by the wind speed sensor 110 is used to characterize the impact of the combined airflow on the user's location, and to find the best airflow direction of the outlet module 210.

[0070] In some embodiments of the present invention, the air outlet module 200 further includes a power detection module 270, which is connected to the energy storage module 260 to detect the stored energy value; the control of the air outlet module 210 to operate the blowing according to the regulated air outlet speed includes:

[0071] The air outlet speed is adjusted based on the change in the energy storage capacity; the smaller the energy storage capacity, the smaller the air outlet speed.

[0072] The power detection module 270 can be a coulomb meter or a negative pressure detection circuit. Since the energy storage module 260 has a limited energy storage capacity, when the energy storage capacity reaches full charge, the air outlet speed can be adjusted to the maximum value. The maximum value of the air outlet speed can be set by the manufacturer or the user according to the actual situation.
