Apparently, the described embodiments are merely some embodiments of the present application, and not all embodiments.

  Hereinafter, a fan switching control method, a device, and a fan according to an embodiment of the present invention will be described with reference to the drawings.

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

  In S101, a travel route of a user located in front of the fan is acquired.

  In the present embodiment, preferably, one infrared matrix sensor is added to the fan body, and the total amount of infrared radiation in the air blowing area of the user can be detected using the infrared matrix sensor. Further, based on the total amount of infrared radiation, it is determined whether or not there is a person in front of the fan body, and when the user is traveling in the airflow area corresponding to the infrared matrix sensor, the infrared matrix sensor emits the user. The total amount of infrared radiation can be detected. In the present embodiment, it is possible to acquire the changing situation of the total infrared radiation amount in the air blowing area corresponding to the fan, and to form the traveling route of the user based on the changing situation.

  If the user approaches the fan from a distance, the total amount of infrared radiation detected by the infrared matrix sensor will increase, and the user's direction of motion can be considered to be the direction of walking toward the fan body, The operation route of the user can be determined based on the change situation of the infrared radiation amount of each infrared sensor in the infrared matrix sensor to be performed. For example, the amount of infrared radiation is detected by the outermost sensor in the infrared matrix sensor, and then, in the direction from the outermost to the central sensor, the amount of infrared radiation of the outermost sensor gradually decreases, If the infrared radiation of the next sensor adjacent to it gradually increases, and then gradually increases to the infrared radiation of the central sensor, and the change stops, the user gradually moves from outside the ventilation area to the front of the fan body. You can think of it as walking.

  As a selectable device, one camera may be installed in the fan, and the traveling route of the user may be determined by the image recognition technology.

  Based on the changing situation of the amount of infrared radiation in the ventilation area corresponding to the fan, a travel route of the user can be formed, and a relative positional relationship between the user and the fan can be determined based on the travel route. For example, assuming that the traveling route is a traveling route in which the user walks from the front of the fan body to the outside of the fan blowing area, it is possible to determine that the traveling route of the user is a traveling route in which the user moves away from the fan. Further, for example, if the travel route is a travel route in which the user enters the front of the fan main body from outside the fan blowing area, it is determined that the user's travel route is a travel route in which the user is approaching the fan. Can be.

  In S102, control is performed to switch the fan based on the traveling route.

  When the traveling route is a traveling route where the user is away from the fan, the fan can be controlled to be switched off, and when the traveling route is a traveling route where the user is approaching the fan, the fan is switched on. Can be controlled as follows.

  According to the switching control method of the fan according to the present embodiment, the traveling route of the user located in front of the fan is acquired, and the control is performed so as to switch the fan based on the traveling route. In this embodiment, based on the travel route of the user, it can be determined whether the user is away from or close to the fan, and further, the fan can be switched on or off. It is possible to determine whether to control, and the switching control of the fan becomes more intelligent and flexible. Since the fan can be controlled to be switched based only on the traveling path of the user, the user can be controlled to switch the fan without depending on the control panel of the existing fan, and the existing fan can be controlled. Solved the problem that the user had to buckle and squat to operate the control button, making the operation inconvenient.

  FIG. 2 is a schematic flow chart of the fan switch-off control method according to the embodiment of the present application. The fan switch off control method includes the following steps.

  In S201, the fan is in a switch-on state.

  In order to realize the execution of the switch-off control for the fan, the fan must first be in the switch-on state.

  In S202, based on the infrared matrix sensor installed in the fan, a change situation of the total infrared radiation amount in the air blowing area corresponding to the fan is acquired.

  In a normal case, the infrared sensor can detect the amount of infrared radiation emitted by a human body. In this embodiment, one infrared matrix sensor is added to the fan body, and the infrared matrix sensor includes a plurality of infrared sensors. When the user is traveling in the air blowing area, the total amount of infrared radiation in the user's air blowing area detected by the infrared matrix sensor also changes. Based on the infrared matrix sensor, it is possible to obtain a change situation of the total infrared radiation amount in the ventilation area corresponding to the fan. The controller installed in the fan can calculate and convert the travel route of the user based on the changing situation of the amount of infrared radiation in the air blowing area.

  In S203, when it is detected that the total infrared radiation amount of the infrared matrix sensor gradually decreases along the first direction until the total infrared radiation amount becomes less than a preset radiation amount threshold value, a first traveling route is formed; The first direction is a direction from the current position where the user is located to outside the blowing area.

  In this embodiment, one radiation amount threshold is set in advance, and when the total infrared radiation amount detected by the infrared matrix sensor is less than the radiation amount threshold, it can be considered that there is no human in front of the fan. In order to control the fan to switch on or off, it is necessary to determine the running direction of the user.

  In this embodiment, the infrared matrix sensor includes a plurality of infrared sensors, and all the infrared sensors in the infrared matrix sensor are used to change the air blowing area in front of the fan main body as shown in FIGS. , In the Y direction. FIG. 3 shows that the blowing area is divided into eight areas in the X direction according to the present embodiment. FIG. 4 shows that the blowing area is divided into eight areas in the Y direction according to the present embodiment. FIG. 5 shows that the blowing area according to the embodiment of the present application is divided into 8 × 8 sub-areas. The 8 × 8 sub-region matrix is formed by dividing the air blowing region into eight regions in the X and Y directions, and all the infrared sensors in the infrared matrix sensor correspond to the divided sub regions one-to-one. Have a relationship. As shown in FIG. 5, the X direction includes X1 to X8, and the Y direction includes Y1 to Y8. The total infrared radiation of the infrared matrix sensor is the radiation from a plurality of sub-regions covered by the user's body. The infrared emission of each sub-region changes as the user moves.

  In the present embodiment, when the detected total infrared radiation amount of the infrared matrix sensor gradually decreases along the first direction until the radiation amount becomes less than a preset radiation amount threshold value, further from the detected sub-region. The traveling direction of the user is determined based on the change in the position of the target sub-region corresponding to the maximum amount of infrared radiation. When the target sub-region corresponding to the maximum infrared radiation amount from the detected sub-region changes from the sub-region corresponding to the current position where the user is located to the sub-region at the boundary of the ventilation region, the traveling direction of the user Is the first direction. If the target sub-region changes from the sub-region corresponding to the current position where the user is located to the sub-region at the boundary of the blowing region, it is assumed that the user has walked from the current position to the coverage of the fan blowing region. It can be considered that the user is gradually moving away from the fan in the traveling process. 6 to 8 are schematic diagrams in which the user is away from the fan. As shown in FIG. 8, after the user gradually walks out of the air blowing area, the body part of the user located in the air blowing area decreases, and the distance between the user and the infrared matrix sensor increases. The amount of infrared radiation detected by the light is weakened.

  For example, as shown in FIG. 9, FIG. 9 is a schematic diagram illustrating a change situation of the position of the target sub-region in the blowing region when the user is away from the fan. The user is walking from the sub-region Y4 to the sub-region Y1 in the X5 direction. The sub-region Y4 is a sub-region corresponding to the current position of the user, and the sub-region Y1 is a sub-region at the boundary of the blowing region. is there. Since the user is initially located in the sub-region Y4, the amount of infrared radiation detected in the sub-region Y4 is the largest. When the user starts moving from the sub-region Y4 to Y3, the amount of infrared radiation in Y4 becomes As the portion of the user entering the Y3 becomes smaller, the infrared radiation at the Y3 becomes the largest, the user continues to move, and the user gradually walks out of the sub-region Y3. Accordingly, the amount of infrared radiation decreases from a large state to a small amount, and accordingly, the amount of infrared radiation detected in the next one sub-region Y2 changes according to the above-mentioned rule as the user moves, and the user changes the sub-region Y1. Until the user starts walking, the detected amount of infrared radiation is less than a preset radiation amount threshold.

  In this embodiment, the controller installed on the fan can determine that the traveling direction of the user is the first direction based on the situation of the position change of the target sub-region, and determine the total infrared radiation amount and the target The first traveling route can be formed based on the position change trajectory of the sub-region. In the present embodiment, the first traveling route is a traveling route where the user is away from the fan.

  In S204, it is determined whether or not the time during which the total amount of infrared radiation is maintained below the radiation amount threshold exceeds a preset first time threshold.

  In this embodiment, one first time threshold is set in advance in order to avoid a situation of switch-off due to the user returning immediately after walking. When the total infrared radiation amount is less than the preset radiation amount threshold, the time of this state is measured, and the time during which the total infrared radiation amount is maintained below the radiation amount threshold is greater than the preset first time threshold. If the value is smaller, it indicates that the user has certainly left the fan blowing area, and S205 is executed. Preferably, the first time threshold is between 10 and 120 seconds.

  In S205, when it is determined that the time during which the total amount of infrared radiation is maintained below the radiation amount threshold exceeds the first time threshold set in advance, control is performed to switch off the fan.

  According to the fan switch-off control method according to the present embodiment, when the fan is in the switch-on state, the fan is positioned in front of the fan based on a change situation of the total infrared radiation amount of the infrared matrix sensor installed in the fan body. It is determined that the user's travel route is the first travel route, and the first travel route switches off the fan if the relative positional relationship between the user and the fan is such that the user is away from the fan. Can be controlled as follows. In this embodiment, by determining that the user is away from the fan based on the user's travel path being the first travel path, by determining to control the fan to switch off, In addition, the fan switch off control becomes more intelligent and flexible, and the user can control to switch off the fan without relying on the existing fan control panel any more. This solves the problem of having to buckle or squat down to operate the, which makes the operation inconvenient.

  FIG. 10 is a schematic flow chart of the fan switch-on control method according to the embodiment of the present application. The fan switch-on control method includes the following steps.

  In S301, the fan is in the switch off state.

  In order to realize controlling the fan to be switched on, the fan must first be in the switched off state.

  In S302, based on the infrared matrix sensor installed on the fan, a change situation of the total infrared radiation amount in the air blowing area corresponding to the fan is acquired.

  For the description regarding S302, the description of the related contents in S202 of the above-described embodiment can be referred to, and the details will not be described here.

  In S303, when 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, the second traveling route is determined. The second direction is a direction from outside the blowing area to a designated area in the blowing area.

  In this embodiment, one radiation amount threshold is set in advance, and when the total infrared radiation amount detected by the infrared matrix sensor is equal to or larger than the radiation amount threshold value, it indicates that there is also a person in front of the fan. In order to control the fan to switch on or off, it is necessary to determine the running direction of the user.

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

  In the present embodiment, if the detected total infrared radiation amount of the infrared matrix sensor gradually increases along the second direction until the radiation amount exceeds a preset radiation amount threshold value, further from the detected sub-region The traveling direction of the user is determined based on the change in the position of the target sub-region corresponding to the maximum amount of infrared radiation. When the target sub-region corresponding to the maximum infrared radiation amount from the detected sub-region changes from the sub-region at the boundary of the ventilation region to the sub-region corresponding to the designated region, the traveling direction of the user is the second direction. Is determined. When the target sub-region changes from the sub-region at the boundary of the blower region to the sub-region corresponding to the designated region, to indicate that the user has entered the cover range of the fan blower region from outside the boundary of the blower region or from the far end. Indicates that the user is approaching the fan in the process of running. 11 to 13 are schematic diagrams showing that the user is approaching the fan. As shown in FIG. 13, when the user gradually enters the air blowing area, the body part of the user located in the air blowing area increases, and when the distance between the user and the infrared matrix sensor becomes short, the infrared The amount of infrared radiation detected by the matrix sensor increases.

  As an example, as shown in FIG. 14, FIG. 14 is a schematic diagram showing a situation in which the position of the target sub-region in the air blowing region changes when the user approaches the fan. In FIG. 14, the designated area is a range included in a broken-line box. In the Y2 direction, the user walks from the sub-region X8 in the Y2 direction to the sub-region X5 in the Y6 direction. When the user enters the sub-region X8, the amount of infrared radiation at X8 is relatively small, and as the portion of the user entering X8 gradually increases, the amount of infrared radiation on X8 increases, and the user continues to move, As the user gradually walks out of the sub-region X8, the amount of infrared radiation gradually decreases from a large state to a small amount, and accordingly, the amount of infrared radiation detected in the sub-region X7 adjacent to the sub-region X8 changes according to the change rule of X8. Begin to. Further, in the sub-region X5 in the Y6 direction, as the distance between the user and the infrared sensor decreases, the detected infrared radiation amount also increases.

  In the present embodiment, the controller installed on the fan can determine that the traveling direction of the user is the second direction based on the position change situation of the target sub-region, and determine the total infrared radiation amount and the target The second travel route can be formed based on the position change trajectory of the sub-region. In the present embodiment, the second traveling route is a traveling route where the user is approaching the fan.

  In S304, it is determined whether or not the time during which the total amount of infrared radiation is maintained at or above the radiation amount threshold exceeds a second time threshold set in advance.

  In this embodiment, one second time threshold is set in advance. When the total infrared radiation amount is equal to or more than the preset radiation amount threshold value, the time of this state is measured, and the time during which the total infrared radiation amount is maintained at or above the radiation amount threshold value is set to the second time threshold value set in advance. If the value is less than the predetermined value, it is determined that the user has certainly entered the designated area in the fan blowing area, and thus S305 is executed. Preferably, the second time threshold is between 1 and 5 seconds.

  As an option, an LED lamp can be installed on the fan body, and if the traveling route of the user is determined to be the first route, the LED lamp is blinked and the fan is controlled to be switched on.
