detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

A method, an apparatus, and a fan for controlling a fan according to an embodiment of the present application are described below with reference to the accompanying drawings.

1 is a schematic flow chart of a method for controlling a fan in an embodiment of the present application. As shown in FIG. 1, the control method of the fan includes the following steps:

S101. Identify an current target posture of a user's limb located in front of the fan based on an infrared matrix sensor disposed on the fan.

In this embodiment, an infrared matrix sensor is added to the fan body, and based on the infrared matrix sensor, infrared radiation emitted by the user's limb can be detected. When the position of the user's limb changes, the area of the infrared radiation that can be detected to emit infrared radiation also changes. For example, if the user's limb changes from the A position to the B position, the infrared radiation area will also change from the A position to the B position accordingly. Further, the current target posture of the user's limb can be identified according to the detected trajectory of the infrared radiation region emitting the infrared radiation. For example, when the user's limb moves in a certain direction, the correspondingly detected infrared radiation-emitting region of the infrared radiation also moves in that direction.

S102. Acquire a target control mode corresponding to the target posture.

In this embodiment, a plurality of control modes may be set in advance, for example, controlling the switch machine, adjusting the wind speed value of the fan, and adjusting the pan angle value of the fan. In order to be able to control the fan according to the user's posture, a correspondence relationship between the gesture and the control mode can be established in advance. After the target posture of the user is recognized, the target control mode corresponding to the target posture can be determined according to the correspondence relationship.

For example, the user's limb may be the user's hand, the hand may move in different directions, and the different moving directions are set to different postures. The user's limb can be the user's head, and can be shaken according to the direction of the head, for example, shaking the head left or right or shaking the head up and down. The user's limb can be the upper limb of the user. The upper limb can draw a certain arc according to different directions, and set the different arc directions of the upper limb to different postures. For example, the upper limb can draw an arc from left to right or from right to left. As two postures, the upper limb draws an arc from left to right or from right to left, and can be used as two postures. Different postures can correspond to different control modes, draw arcs from left to right, and draw arcs from right to left to adjust the wind speed, draw arrows from left to right, and draw arcs from right to left. You can adjust the head angle accordingly.

S103. Control the fan accordingly according to the target control mode.

After the target control mode is determined according to the target posture, the fan can be controlled accordingly. For example, when the target control mode is to adjust the wind speed value of the fan, the wind speed value can be adjusted based on the current fan value.

The control method of the fan provided in this embodiment is based on the infrared matrix sensor disposed on the fan, identifying the current target posture of the user's limb located in front of the fan, acquiring the target control mode corresponding to the target posture, and correspondingly controlling the fan based on the target control mode. control. In this embodiment, the current posture of the user can be determined according to the infrared matrix sensor disposed on the fan, thereby determining the control mode of the fan, so that the control of the fan is more intelligent and flexible. Since the fan can be controlled according to the posture of the user, such as switching on and off, adjusting the wind speed, and adjusting the head angle, the user can no longer rely on the control panel of the existing fan or the remote controller of the fan to control the fan, thereby solving the existing The problem that the user in the fan needs to bend or squat to operate the control panel or if the remote controller is lost or cannot be found, resulting in inconvenient operation.

FIG. 2 is a schematic flowchart diagram of another method for controlling a fan according to an embodiment of the present disclosure. The control method of the fan provided in this embodiment is explained by taking the user's limb as the user's hand as an example.

The control method of the fan includes the following steps:

S201. Acquire a change track of an infrared radiation region emitting infrared radiation in a coverage area corresponding to the infrared matrix sensor.

In general, the infrared sensor can detect the infrared radiation emitted by the user's hand. An infrared sensor is disposed on the existing fan body. In this embodiment, an infrared matrix sensor is used to replace a single infrared sensor on the existing fan body, wherein the infrared matrix sensor includes a plurality of infrared sensors. The infrared matrix sensor can be placed at the height of the fan body 30-160CM. When the position is low, it can be tilted at a certain angle, so that the infrared matrix sensor can be aligned parallel to the palm of the user's hand, as shown in Figures 3 and 4. When the position of the user's hand changes, the area of the infrared radiation that can be detected to emit infrared radiation also changes. The controller disposed in the fan can calculate a target gesture converted into a user's hand according to a change trajectory of the infrared radiation region in the coverage area.

S202. When the detected infrared radiation area remains unchanged for a preset duration, determine the target posture as the first gesture for power on/off control.

When the user's hand stays in an area within the coverage of the infrared matrix sensor, the detected infrared radiation area will stay at the current position and will not change. In this embodiment, a duration is set in advance, and when the infrared radiation region remains unchanged for a preset duration, the target gesture may be determined as the first gesture for turning the power on and off.

In this embodiment, the coverage area of the infrared matrix sensor is divided into a plurality of regions in the X and Y directions, as shown in FIGS. 5 and 6. FIG. 5 divides the coverage area into eight areas in the X direction according to the embodiment. FIG. 6 divides the coverage area into eight areas in the Y direction according to the embodiment. FIG. 7 is a sub-area in which the coverage area is divided into 8*8 according to an embodiment of the present application. The 8*8 sub-area matrix is formed by dividing the coverage area into eight areas in the XY direction. Wherein, the infrared sensor forms a one-to-one correspondence with the sub-areas. As shown in FIG. 7, the X direction includes: X1 to X8, and the Y direction includes: Y1 to Y8. The amount of infrared radiation detected by the infrared matrix sensor comes from multiple sub-areas covered by the user's palm. The infrared radiation of each sub-area changes as the user's hand moves.

Figure 8 is a schematic illustration of the user's palm in the coverage area of the infrared matrix sensor. In Figure 8, the infrared radiation area corresponding to the palm of the user is the area in the virtual frame. When the user extends the palm of the hand in the area of the virtual frame for a preset period of time, the target gesture can be identified as adjusting the first posture for turning the machine on and off.

S203. Determine whether the detected amount of infrared radiation is within a preset range.

When the user reaches into the infrared matrix sensor, the amount of infrared radiation detected by the infrared matrix sensor increases as the user's hand enters the coverage area more and more. In practical applications, the user's palm extends and needs to cover more than half of the infrared matrix sensor. In Figure 8, the infrared matrix sensor divides the coverage area into 8*8=64 sub-areas, and the palm needs to cover at least 8 or more areas, and The deviation of the amount of infrared radiation at each point is within +/- 20%.

Under normal circumstances, the coverage of the infrared matrix sensor will exceed the coverage of the user's hand, so when the user's hand is completely within the coverage of the infrared matrix sensor, the amount of infrared radiation detected will be stable within a range. In this embodiment, a range can be set in advance.

It is judged whether the user's hands are all within the coverage of the infrared matrix sensor by judging whether the detected amount of infrared radiation is within a preset range. When it is judged that the detected amount of infrared radiation is within a preset range, then S204 is performed.

S204. If the detected amount of infrared radiation is within a preset range, the current working state of the fan is identified.

In this embodiment, the working state of the fan may include a power on state and a power off state. When the detected amount of infrared radiation is within a preset range, since it is determined that the target posture is the first gesture for power on/off control, it is necessary to recognize the current working state of the fan. When the current working state is not turned on, S205 is executed; when the current working state is not turned on, 207 is performed.

S205. If the current working state is the power-on state, determine that the target control mode is the shutdown control.

When it is recognized that the current target posture of the user is the first gesture, and the fan is currently in the power-on state, indicating that the user attempts to turn off the fan, it may be determined that the target control mode is the shutdown control.

S206. Perform shutdown control on the fan.

After determining that the target control mode is the shutdown control, the fan can be shut down based on the shutdown control.

S207. If the current working state is the shutdown state, determine that the target control mode is the power-on control.

When it is recognized that the current target posture of the user is the first gesture, and the fan is currently in the shutdown state, indicating that the user attempts to turn on the fan, it may be determined that the target control mode is the power-on control.

S208: Turn on the fan to control.

After determining that the target control mode is the power-on control, the fan can be powered on based on the power-on control.

The control method of the fan provided in this embodiment detects the change trajectory of the infrared radiation region according to the infrared matrix sensor disposed on the fan body, and determines when the detected infrared radiation region maintains the position within a preset duration. The current target posture is a first gesture for turning on and off, and further, the fan is on/off controlled according to the first gesture and the working state in which the fan is currently in operation. In this embodiment, the fan can be automatically controlled according to the current gesture of the user, and the fan switch control is more intelligent and flexible, so that the user can no longer rely on the control panel of the existing fan or the remote controller of the fan.
