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.

The method and device for controlling the fan switch machine and the fan of the 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 switch machine in an embodiment of the present application. As shown in FIG. 1, the fan switch control method includes the following steps:

S101. Acquire a walking path of a user located in front of the fan.

In this embodiment, an infrared matrix sensor is preferably added to the fan body, and based on the infrared matrix sensor, the total amount of infrared radiation of the user in the air supply area can be detected. Further, determining whether there is a person in front of the fan body according to the total amount of infrared radiation, the infrared matrix sensor can detect the total amount of infrared radiation emitted by the user when the user walks in the air blowing region corresponding to the infrared matrix sensor. In this embodiment, the change of the total amount of infrared radiation in the air supply area corresponding to the fan can be obtained, and the walking path of the user can be formed according to the change.

When the user approaches the fan from a distance, the total amount of infrared radiation detected by the infrared matrix sensor will gradually become larger, indicating that the user's moving direction is toward the fan body, and further, each infrared sensor in the detected infrared matrix sensor The change in the amount of infrared radiation can determine the user's operating path. For example, when the outermost sensor in the infrared matrix sensor detects the amount of infrared radiation, and then from the outermost direction to the direction of the intermediate sensor, the amount of infrared radiation of the outermost sensor gradually decreases while the next sensor adjacent thereto The amount of infrared radiation gradually becomes larger until the amount of infrared radiation of the intermediate sensor becomes larger and stops changing, which indicates that the user is gradually from the outside of the air supply area. Go to the front of the fan body.

Optionally, a camera can be disposed on the fan to determine the walking path of the user by image recognition technology.

After the change of the amount of infrared radiation in the air supply area corresponding to the fan, the traveling path of the user may be formed, and the relative positional relationship between the user and the fan is determined according to the walking path, for example, when the walking path is the user from the fan body Directly forward, go outside the air supply area of the fan, you can determine that the user's walking path is for the user to leave the fan. For another example, when the walking path is that the user enters directly from the air blowing area of the fan directly in front of the fan body, it can be determined that the user's walking path is that the user is close to the fan.

S102. Perform on/off control of the fan according to the walking path.

When the walking path is away from the fan, the fan can be shut down, and when the walking path is the user approaching the fan, the fan can be powered on.

In the fan switch control method provided in this embodiment, the fan is controlled to be turned on and off according to the travel path by acquiring the travel path of the user located in front of the fan. In this embodiment, according to the walking path of the user, it can be determined whether the user is away from the fan or close to the fan, so that it can be determined whether the fan is powered on or off, so that the fan on/off control is more intelligent and flexible. Since the fan can be controlled by the switch according to the user's walking path, the user can no longer rely on the control panel of the existing fan to control the fan, which solves the problem that the user needs to bend or squat in the existing fan to operate and control. Buttons cause problems that are not convenient to operate.

FIG. 2 is a schematic flowchart diagram of a fan shutdown control method according to an embodiment of the present disclosure. The fan shutdown control method includes the following steps:

S201. The fan is powered on.

In order to achieve shutdown control of the fan, the fan first needs to be powered on.

S202. Acquire an infrared pixel sensor disposed on the fan to obtain a change of the total infrared radiation amount in the air supply area corresponding to the fan.

In general, an infrared sensor can detect the amount of infrared radiation emitted by the human body. In this embodiment, an infrared matrix sensor is added to the fan body, and the infrared matrix sensor includes a plurality of infrared sensors. When the user walks in the air supply area, the infrared matrix sensor detects that the total amount of infrared radiation of the user in the air supply area also changes. Based on the infrared matrix sensor, the change of the total infrared radiation amount in the air supply area corresponding to the fan can be obtained. The controller disposed in the fan can be converted into a user walking path according to the change of the amount of infrared radiation in the air supply area.

S203. If it is detected that the total infrared radiation amount of the infrared matrix sensor gradually decreases along the first direction to be lower than a preset radiation amount threshold, forming a first walking path, where the first direction is from the current position where the user is located. Direction outside the air supply area.

In this embodiment, a radiation amount threshold is set in advance. When the total infrared radiation amount detected by the infrared matrix sensor is lower than the radiation amount threshold, it can be stated that the fan is not in front. In order to control the fan to be turned on or off, it is also necessary to determine the direction in which the user walks.

In this embodiment, the infrared matrix sensor includes a plurality of infrared sensors, and all the infrared sensors in the infrared matrix sensor divide the air supply area in front of the fan body into a plurality of regions in the X and Y directions, as shown in FIG. 3 and FIG. 4 is shown. FIG. 3 divides the air supply area into eight areas in the X direction according to the embodiment. FIG. 4 divides the air blowing area into eight areas in the Y direction according to the embodiment. FIG. 5 is a sub-area in which the air supply area is divided into 8*8 according to an embodiment of the present application. The 8*8 sub-area matrix is formed by dividing 8 regions of the air supply region in the XY direction, and all the infrared sensors in the infrared matrix sensor have a one-to-one correspondence with the divided sub-regions. As shown in FIG. 5, the X direction includes: X1 to X8, and the Y direction includes: Y1 to Y8. The total amount of infrared radiation from the infrared matrix sensor comes from multiple sub-areas covered by the user's body. The infrared radiation of each sub-area changes as the user moves.

In this embodiment, when the total infrared radiation amount of the detected infrared matrix sensor is gradually decreased along the first direction to be lower than a preset radiation amount threshold, further, according to the detected maximum infrared radiation amount from the sub-region The position of the corresponding target sub-area changes to determine the direction of travel of the user. When the target sub-area corresponding to the maximum amount of infrared radiation from the sub-area is detected, and the sub-area corresponding to the current position of the user is changed to the sub-area of the boundary of the air supply area, the user's walking direction is determined to be the first direction. . Since the target sub-area changes from the sub-area corresponding to the current location where the user is located to the sub-area of the boundary of the air supply area, the user is out of the coverage of the air supply area of the fan from the current position, indicating that the user is gradually in the process of walking. Keep away from the fan. 6 to 8 are schematic views of the user moving away from the fan. As shown in FIG. 8, when the user gradually walks out of the air supply area, the part of the user's body in the air supply area becomes less and less, and since the user is farther away from the infrared matrix sensor, the infrared matrix sensor detects The amount of infrared radiation will become weaker and weaker.

For example, as shown in FIG. 9 , it is a schematic diagram showing a change in the position of the target sub-area in the air supply area when the user is away from the fan. When the user is in the X5 direction, the user moves out of the sub-area Y1 from the sub-area Y4, wherein the sub-area Y4 is the sub-area corresponding to the current position of the user, and the sub-area Y1 is the air supply area. A subregion of a domain boundary. Since the user starts to be in the sub-area Y4, the amount of infrared radiation detected on the sub-area Y4 is the largest, and the user moves from the sub-area Y4 to Y3, and the amount of infrared radiation on Y4 starts to become smaller, and as the user enters Y3 More and more, the infrared radiation on Y3 will gradually become the maximum, the user continues to move, the user will gradually go out from the sub-area Y3, then the amount of infrared radiation will gradually become smaller, correspondingly, the next sub The amount of infrared radiation detected by the area Y2 also changes according to the above-mentioned law as the user moves, until the user exits from the sub-area Y1, and the detected amount of infrared radiation is lower than the preset radiation amount threshold.

In this embodiment, according to the position change of the target sub-area, the controller disposed on the fan may determine that the traveling direction of the user is the first direction, and may change the trajectory according to the total infrared radiation amount and the position of the target sub-area. A first walking path is formed. In this embodiment, the first walking path is that the user is away from the fan.

S204. Determine whether the total infrared radiation amount is lower than the radiation amount threshold, and the maintenance time exceeds a preset first time threshold.

In this embodiment, in order to avoid the shutdown situation that occurs when the user just walks away and returns immediately, a first time threshold is set in advance. When the total infrared radiation amount is lower than the preset radiation amount threshold, the state can be timed. When the total infrared radiation amount is lower than the radiation amount threshold, the maintenance time is lower than the preset first time threshold, indicating that the user is indeed The air supply area of the fan is left, and S205 is executed. The first time threshold is preferably 10-120 seconds.

S205. When it is determined that the total infrared radiation amount is lower than the radiation amount threshold, the maintenance time exceeds a preset first time threshold, and then the fan is shut down.

The fan shutdown control method provided in this embodiment determines that the walking path of the user located in front of the fan is the first walking according to the change of the total infrared radiation amount on the infrared matrix sensor disposed on the fan body when the fan is in the power-on state. The path, wherein the first walking path indicates a relative positional relationship between the user and the fan, so that the user is away from the fan, and the fan can be shut down. In this embodiment, the walking path of the user may be the first walking path, and the user may be determined to be away from the fan, so that the fan can be determined to be shut down, so that the fan shutdown control is more intelligent and flexible, and the user can no longer rely on the existing fan. The middle control panel performs shutdown control on the fan, which solves the problem that the user needs to bend or squat to operate the control button in the existing fan, resulting in inconvenient operation.

FIG. 10 is a schematic flowchart diagram of a fan booting control method according to an embodiment of the present disclosure. The fan boot control method includes the following steps:

S301. The fan is in the off state.

In order to control the fan, the fan needs to be turned off first.

S302. Acquire an infrared pixel sensor disposed on the fan to obtain a change of the total infrared radiation amount in the air supply area corresponding to the fan.

For the description of S302, refer to the description of related content in S202 in the foregoing embodiment, and details are not described herein again.

S303. If it is detected that the total infrared radiation amount of the infrared matrix sensor gradually increases along the second direction and exceeds a preset radiation amount threshold, forming a second traveling path, wherein the second direction is to send air from the outside of the air supply area. The direction of the specified area within the area.

In this embodiment, a radiation amount threshold is set in advance. When the total infrared radiation amount detected by the infrared matrix sensor is higher than or equal to the radiation amount threshold, it can be stated that there is a person in front of the fan. Since it is necessary to determine whether the fan is to be turned on or off, it is also necessary to determine the direction in which the user is traveling.

In this embodiment, the air blowing area in front of the fan main body is divided into a plurality of areas in the X and Y directions, and the process after the air blowing area is divided can be referred to FIG. 3 to FIG. The total amount of infrared radiation from the infrared matrix sensor comes from multiple sub-areas covered by the user's body. The infrared radiation of each sub-area changes as the user moves.

In this embodiment, when the total amount of infrared radiation of the detected infrared matrix sensor increases gradually along the second direction to be higher than or equal to a preset radiation amount threshold, further, according to the detection of the maximum infrared from the sub-area The position of the target sub-region corresponding to the amount of radiation changes to determine the direction of travel of the user. When the target sub-area corresponding to the maximum amount of infrared radiation from the sub-area is detected, and the sub-area corresponding to the boundary of the air-sending area is changed to the sub-area corresponding to the designated area, it is determined that the traveling direction of the user is the second direction. Since the target sub-area changes from the sub-area of the air supply area boundary to the sub-area corresponding to the designated area, the coverage of the air supply area outside the boundary of the user air supply area or the far end enters the coverage area of the air supply area of the fan, indicating that the user is walking. Medium, gradually approaching the fan. 11 to 13 are schematic views of the user approaching the fan. As shown in FIG. 13, when the user gradually enters the air supply area, the user's body is more and more in the air supply area, and since the user is closer to the infrared matrix sensor, the infrared matrix sensor detects The amount of infrared radiation will become stronger and stronger.

For example, as shown in FIG. 14 , it is a schematic diagram showing a change in the position of the target sub-area in the air supply area when the user approaches the fan. In Figure 14, the designated area is the range included in the virtual box. In the Y2 direction, the user goes from the sub-area X8 in the Y2 direction to the sub-area X5 in the Y6 direction. When the user just When entering the sub-area X8, the amount of infrared radiation on the X8 will be relatively small, and as the user enters the X8 part more and more, the amount of infrared radiation on the X8 will become larger, and the user will continue to move, and the user will follow the sub-area. When the area X8 gradually goes out, the amount of infrared radiation gradually decreases from large to large, and accordingly, the amount of infrared radiation detected on the sub-area X7 adjacent to the sub-area X8 starts to change according to the variation rule of X8. Further, the sub-region X5 in the Y6 direction is getting closer and closer as the user is closer to the infrared sensor, and the amount of infrared radiation detected is also increasing.

In this embodiment, according to the change of the position of the target sub-area, the controller disposed on the fan may determine that the traveling direction of the user is the second direction, and may change the trajectory according to the total infrared radiation amount and the position of the target sub-area. A second walking path is formed. In this embodiment, the second walking path is that the user is close to the fan.

S304. Determine whether the total infrared radiation amount is higher than or equal to the radiation amount threshold, and the maintenance time exceeds a preset second time threshold.

In this embodiment, a second time threshold is set in advance. When the total infrared radiation amount is higher than or equal to the preset radiation amount threshold, the state may be timed when the total infrared radiation amount is higher than or equal to the radiation amount threshold when the maintenance time is lower than the preset second time threshold. It is stated that the user has actually entered the designated area in the air supply area of the fan, and S305 is executed. The second time threshold is preferably 1-5 seconds.

Optionally, an LED light can be disposed on the fan body. When it is determined that the user's walking path is the first path, the LED light flashes to remind the user that the fan will be powered on, and when the user sees the LED light flashing, If you do not want to turn on the fan, you can quickly leave the current area within the second time threshold to avoid accidental opening of the fan. S305. After determining that the total infrared radiation amount is higher than or equal to the radiation amount threshold, the maintenance time exceeds a preset second time threshold, and then the fan is powered on.

In the fan power-on control method provided in this embodiment, when the fan is in a shutdown state, the user's walking path in front of the fan is determined to be the second walking according to the change of the total infrared radiation amount on the infrared matrix sensor disposed on the fan body. The path, wherein the two walking paths indicate a relative positional relationship between the user and the fan, so that the user is close to the fan, and the fan can be powered on. In this embodiment, the user can follow the walking path of the user as the second walking path, and can determine that the user is close to the fan, so that the fan can be determined to be powered on, so that the fan shutdown control is more intelligent and flexible, and the user can no longer rely on the existing fan. The middle control panel controls the fan to be turned on, which solves the problem that the user needs to bend or squat in the existing fan to operate the control button, resulting in inconvenient operation.
