Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic diagram illustrating a control method of an intelligent range hood according to an exemplary embodiment, and as shown in fig. 1, the method is used in the intelligent range hood and includes the following steps 101 and 104:
in step 101, a target motion of the user is identified by the information detected by the at least two motion recognition probes.
Here, the front panel of the intelligent range hood is provided with at least two motion recognition probes, wherein at least one motion recognition probe is located on a first side, at least one motion recognition probe is located on a second side, the first side and the second side are opposite sides, the first side and the second side may be the left side and the right side of the front panel, or the upper side and the lower side of the front panel, and the first side and the second side are the left side and the right side of the front panel in the following embodiments. For example, fig. 2 is a schematic diagram of a motion recognition probe on an intelligent range hood according to an exemplary embodiment, and as shown in fig. 2, two motion recognition probes, namely, a motion recognition probe 21 on the left side and a motion recognition probe 22 on the right side, may be disposed on a front panel 20 of the intelligent range hood.
Here, the intelligent range hood is provided with a control circuit board, the control circuit board is connected with the motion recognition probes, and can recognize a target motion of a user through signals detected by the motion recognition probes on two sides, the target motion comprises a hand waving motion in a target direction, a hovering motion of a target position and a hovering motion after hand waving in the target direction, wherein the target direction comprises a first direction from a first side to a second side or a second direction from the second side to the first side, and the target position comprises a first side position and/or a second side position. For example, taking the first side as the left side and the second side as the right side as an example, the target actions include a waving action from left to right, a waving action from right to left, a hovering action at a left position, a hovering action at a right position, a hovering action after waving from left to right, and a hovering action after waving from right to left.
In step 102, when the intelligent range hood is in a standby state and the target motion is a hand waving motion in a first direction, controlling the intelligent range hood to execute a command for starting a weak wind mode; and when the target motion is taken as a hand waving motion in a second direction, controlling the intelligent range hood to execute an instruction for starting the work in the strong wind mode.
In step 103, when the intelligent range hood is in the on state and the target motion is a hand waving motion in the first direction or the second direction, the intelligent range hood is controlled to execute an instruction for turning off the intelligent range hood.
In step 104, when the intelligent range hood is in a starting state and the target action is taken as a hovering action of a first side position, controlling the intelligent range hood to execute an instruction of reducing air volume; and when the target action is taken as the hovering action of the second side position, controlling the intelligent range hood to execute an instruction for increasing the air volume.
Here, the control circuit board may store a corresponding relationship between each target motion and a command of the intelligent range hood, where the command may include a power-on command, a power-off command, and a wind power adjustment command of the intelligent range hood, and after the control circuit board identifies a target motion of a user, the control circuit board may execute a command corresponding to the identified target motion according to the corresponding relationship.
Here, in the standby state of the intelligent hood, a waving motion in a first direction from the first side to the second side corresponds to a command to start a weak wind mode operation, and a waving motion in a second direction from the second side to the first side corresponds to a command to start a strong wind mode operation. When the intelligent range hood is in the starting state, the hand waving action in the first direction or the second direction corresponds to an instruction for closing the intelligent range hood. In addition to the start and stop commands, the user sometimes needs a larger air volume to smoke vigorously during the cooking process, and sometimes only needs a smaller air volume to smoke vigorously, so that some corresponding relations between the target actions and the air volume adjusting commands need to be set so that the user can adjust the air volume through the target actions. In this embodiment, the hovering action at the first side position may be set to correspond to an instruction for decreasing the air volume, and the hovering action at the second side position may be set to correspond to an instruction for increasing the air volume.
The following description of the use of the intelligent range hood is given by taking the first side as the left side and the second side as the right side as an example:
when the intelligent range hood is in a standby state and a user wants to control the intelligent range hood to start a weak wind mode to work, the user can swing a hand from the left motion recognition probe to the right motion recognition probe, the control circuit board can determine that a target motion of the user is a hand swinging motion from left to right according to information detected by the left motion recognition probe and the right motion recognition probe, and at the moment, the control circuit board can control the intelligent range hood to execute an instruction of reducing the wind volume. Certainly, if the user wants to start the operation in the strong wind mode, the user can swing the hand from the right motion recognition probe to the left motion recognition probe, at this time, the control circuit board can determine the target motion of the user as the right-to-left hand swinging motion according to the information detected by the left motion recognition probe and the right motion recognition probe, and at this time, the control circuit board can control the intelligent range hood to execute the instruction for starting the operation in the strong wind mode.
When the intelligent range hood is in operation and a user wants to close the intelligent range hood, the user can swing a hand from the left motion recognition probe to the right motion recognition probe or swing the hand from the right motion recognition probe to the left motion recognition probe, then the control circuit board can determine that a target motion of the user is a hand waving motion from left to right or a hand waving motion from right to left according to information detected by the left motion recognition probe and the right motion recognition probe, and at the moment, the control circuit board can control the intelligent range hood to execute an instruction for closing the intelligent range hood.
When the user wants to reduce the air volume, the user can hover the action recognition probe with the hand extending to the left side, the control circuit board can determine the target action of the user as the hovering action of the left side according to the information detected by the left action recognition probe, and at the moment, the control circuit board can control the intelligent range hood to execute the instruction of reducing the air volume. Of course, if the user wants to increase the air volume, the user can hover the motion recognition probe with the hand extending to the right side, the control circuit board can determine the target motion of the user as the hovering motion of the right side according to the information detected by the motion recognition probe at the right side, and at this time, the control circuit board can control the intelligent range hood to execute the instruction of increasing the air volume.
Of course, when the first side is the right side and the second side is the left side, the use of the intelligent range hood is similar to that described above, and reference is made to the above description, which is not illustrated one by one.
It should be noted here that in some other embodiments, an instruction for turning down the air volume corresponding to the hover action after waving in the first direction from the first side to the second side may be further set, and an instruction for increasing the air volume corresponding to the hover action after waving in the second direction from the second side to the first side may be further set; the left-side hover action is set to correspond to an instruction to page down from the current page of the display screen, and the right-side hover action is set to correspond to an instruction to page up from the current page of the display screen, which is not limited herein.
The embodiment can identify a plurality of target actions of a user through at least two action identification probes, and then control the intelligent range hood to execute the identified instructions corresponding to the target actions according to the corresponding relation between the prestored target actions and the instructions, wherein the instructions comprise a power-on/off instruction, a wind power adjusting instruction and a page turning instruction.
In a possible embodiment, fig. 3 is a schematic diagram illustrating a control method of an intelligent range hood according to an exemplary embodiment, and as shown in fig. 3, the control method of the intelligent range hood may further include step 105.
In step 105, when the intelligent range hood is provided with a display screen, the intelligent range hood is in a power-on state, and the display screen is used for displaying an intelligent menu, and when the target action is a hand waving hovering action in a first direction, the intelligent range hood is controlled to execute an instruction for turning down one page from a current page of the display screen; and when the target action is a hand-waving hovering action in a second direction, controlling the intelligent range hood to execute an instruction of turning up one page from the current page of the display screen.
Here, the intelligent range hood is provided with a display screen, the display screen may display an intelligent menu, and when a user uses the intelligent menu in a cooking process, the user needs to turn a page back and forth to view the menu, so that some corresponding relations between target actions and air volume adjusting instructions may be set, so that the user adjusts the air volume through the target actions.
The following description will be given by taking the first side as the left side and the second side as the right side as an example, if a user wants to turn down a page from a current page displayed on the display screen, the user can swing the hand from the left-side motion recognition probe to the right-side motion recognition probe and suspend the hand for a period of time, the control circuit board can determine that the target motion of the user is a motion of hovering the user after swinging the hand from left to right according to information detected by the left-side motion recognition probe and the right-side motion recognition probe, and at this time, the control circuit board can control the intelligent range hood to execute an instruction of turning down a page from the current page of the display screen. Of course, if the user wants to turn up a page from the current page, the user can swing the hand from the right motion recognition probe to the left motion recognition probe, the control circuit board can determine the target motion of the user as the motion of hovering after swinging the hand from right to left according to the information detected by the left motion recognition probe and the right motion recognition probe, and at this time, the control circuit board can control the intelligent range hood to execute an instruction of turning up a page from the current page of the display screen.
Of course, when the first side is the right side and the second side is the left side, the use of the intelligent range hood is similar to that described above, and reference is made to the above description, which is not illustrated one by one.
It should be noted here that in some other embodiments, an instruction for turning down the air volume corresponding to the hover action after waving in the first direction from the first side to the second side may be further set, and an instruction for increasing the air volume corresponding to the hover action after waving in the second direction from the second side to the first side may be further set; the left-side hover action is set to correspond to an instruction to page down from the current page of the display screen, and the right-side hover action is set to correspond to an instruction to page up from the current page of the display screen, which is not limited herein.
In a possible embodiment, step 101 in the above-mentioned control method of the intelligent cigarette machine may also be implemented as the following steps a1 and a 2.
In step a1, the motion recognition probe detects information as to whether or not the corresponding position of the motion recognition probe is blocked by an object.
In step a2, the target motion of the user is recognized based on the information as to whether the corresponding position of the motion recognition probe is blocked by an object.
Here, the motion recognition probe is used to recognize information whether the corresponding position of the motion recognition probe is blocked by an object, and the control circuit board may recognize a target motion of the user according to the information whether the corresponding position of each motion recognition probe is blocked by an object. For example, if the one-side action recognition probe detects that the corresponding position of the action recognition probe is shielded by an object for a preset time, the control circuit board may recognize the target action of the user as the hovering action on the one side of the action recognition probe.
In one possible embodiment, the motion recognition probe includes any one of a camera, an infrared sensor, and an ultrasonic sensor; the motion recognition probe is used for recognizing whether the corresponding position of the motion recognition probe is shielded by an object, for example, when the motion recognition probe is a camera, whether the corresponding position of the motion recognition probe is shielded by the object can be determined through a shot image; when the motion recognition probe is an infrared sensor, whether the corresponding position is shielded by an object can be determined by sensing infrared rays radiated by a target; when the motion recognition probe is an ultrasonic sensor, whether the corresponding position is shielded by an object can be determined by receiving an ultrasonic signal reflected by the target object.
In a possible embodiment, the distance between the motion recognition probe on the first side and the motion recognition probe on the second side is not easy to be too small, so as to prevent the motion recognition probes on the two sides from being recognized by mistake, and the distance between the motion recognition probe on the first side and the motion recognition probe on the second side is not easy to be too large, so that the gesture range of a user is prevented from being too large and the operation is not easy to be performed. Therefore, it is preferable that the distance range between the first side motion recognition probe and the second side motion recognition probe includes 200mm to 800 mm.
In a possible embodiment, the step a2 in the control method of the intelligent range hood can be further implemented as the following steps a21 to a 24.
In step a21, when the object detected by the one motion recognition probe is occluded, the first timer is started, and when the first occluded time period between the occlusion of the object detected by the one motion recognition probe and the detection of the non-occlusion of the object is recorded, the first timer is ended.
In step a22, the second time measurement is started when the first time measurement is finished, and the second time measurement is finished when a delay time period is recorded between the detection by the motion recognition probe on the one side that is not blocked by the object and the detection by the motion recognition probe on the other side that is blocked by the object.
In step a23, the third time measurement is started when the second time measurement is finished, and the third time measurement is finished when the second occluded time period is recorded until the occlusion by the object detected by the other motion recognition probe is not detected.
In step a24, when the first and second occluded durations are both within a first preset duration range and the delay duration is within a second preset duration range, the target action is identified as a hand-waving action in the target direction.
Here, the motion recognition probes on both sides may detect whether or not they are shielded by an object, and an MCU (micro controller Unit) and a timer are provided in the control circuit board.
Here, when the user swings his hand from one side to the other side, the hand of the user is positioned in front of the motion recognition probe on the one side to shield the motion recognition probe on the one side, and then swings to the front of the motion recognition probe on the other side after a while to shield the motion recognition probe on the other side. When the control circuit board identifies the waving hand from one side to the other side, the timer can sequentially count time for three times, record the first shielded time length from the time when the motion recognition probe at one side detects that the motion recognition probe at one side is shielded by the object to the time when the motion recognition probe at one side detects that the motion recognition probe at the other side is not shielded by the object to the time when the motion recognition probe at one side detects that the motion recognition probe at the other side is shielded by the object; and the action recognition probe on the other side detects a second shielded time period from the shielding of the object to the non-shielding of the object. And if the timing is sequentially finished for three times, the first shielded duration and the second shielded duration are both within the first preset duration range, and the delay duration is within the second preset duration range, indicating that the user is a hand waving action from one side to the other side. Of course, if only one or two times of timing are completed, it indicates that the user is not performing the hand-waving motion.
Here, when the one side is a first side and the other side is a second side, the target direction is a first direction, when the one side is a second side and the other side is a first side, the target direction is a second direction, in this embodiment, the first side is a left side and the second side is a right side, and then the target direction is a first direction from left to right or a second direction from right to left.
Taking one side as the left side and the other side as the right side as an example, the first preset time period ranges from 10ms to 500ms, and the second preset time period ranges from 200ms to 5000 ms. When the left motion recognition probe detects the occlusion by the object, the timer starts to count for the first time to obtain a first occluded time length t1 (the first counting is from the beginning of the occlusion by the left motion recognition probe to the end of the restoration to the non-occluded state), when the left motion recognition probe returns to the non-occluded state, the timer starts to count for the second time to obtain a time length t2 (the second counting is from the beginning of the restoration to the non-occluded state by the object to the end of the recognition to the occlusion by the right motion recognition probe), when the right motion recognition probe recognizes the occlusion by the object, the timer starts to count for the third time to obtain an occluded time length t3 (the third counting is from the beginning of the detection by the object to the end of the restoration to the non-occluded state by the object by the left motion recognition probe), if the conditions that 10ms is not less than t1/t3 not less than 500ms and that 200ms is not less than t2 not less, the MCU of the control circuit board determines that the current target motion is a left-to-right hand waving motion. The hand waving motion from right to left is similar to the above determination and will not be described again.
Therefore, when the intelligent range hood is in a standby state, when a user wants to control the intelligent range hood to start the weak wind mode to work, the user can swing the hand from the left motion recognition probe to the right motion recognition probe, the control circuit board can count three times through the timer to obtain first sheltered duration, delay duration and second sheltered duration, the first sheltered duration and the second sheltered duration are within a first preset duration range, the delay duration is within a second preset duration range, the MCU of the control circuit board determines that the target motion detected by the user when the intelligent range hood is in the standby state is the hand swinging motion from left to right, and at the moment, the MCU can control the intelligent range hood to execute an instruction for starting the weak wind mode to work. Of course, if the user wants to increase the air volume, the user can swing the hand from the right-side motion recognition probe to the left-side motion recognition probe, at this time, the MCU of the control circuit board can determine that the target motion of the user is the right-to-left hand swinging motion when the intelligent range hood is in the standby state, and at this time, the MCU can control the intelligent range hood to execute the start-up strong wind mode.
When the intelligent range hood is in a starting state, when a user wants to control the intelligent range hood to be closed, the user can swing a hand from the left motion recognition probe to the right motion recognition probe or swing the hand from the right motion recognition probe to the left motion recognition probe, the control circuit board can be timed for three times through the timer to obtain first sheltered duration, delay duration and second sheltered duration, the first sheltered duration and the second sheltered duration are within a first preset duration range, the delay duration is within a second preset duration range, the MCU of the control circuit board determines that the target motion detected by the user when the intelligent range hood is in the starting state is the hand swinging motion from left to right or the hand swinging motion from right to left, and at the moment, the MCU can close the intelligent range hood.
It should be noted that the second preset time length range may be determined according to a distance range between the motion recognition probe on the first side and the motion recognition probe on the second side, and if the distance between the probes on the two sides is larger, the second preset time length may be correspondingly set to be larger.
In a possible embodiment, the step a2 in the control method of the intelligent range hood can be further implemented as the following step a 25.
In step a25, when the first occluded duration is within the first preset duration range, the delay duration is within a second preset duration range, and the second occluded duration is within a third preset duration range, the target motion is identified as the waving hovering action in the target direction.
Here, the duration in the third preset duration range is greater than the duration in the first preset duration range.
Still taking one side as the left side and the other side as the right side as an example, the first preset time range is 10ms to 500ms, the second preset time range is 200ms to 5000ms, the third preset time range includes more than or equal to 500ms, when the motion recognition probe on the left side detects the occlusion by the object, the timer starts to count for the first time to obtain a first occluded time t1 (the first time starts from the detection of the occlusion by the object by the motion recognition probe on the left side to end to recover to the non-occluded state again), when the motion recognition probe on the left side recovers to the non-occluded state, the second time starts to count for the second time to obtain Δ t2 (the second time starts from the recovery of the motion recognition probe on the left side to the non-occluded state by the object to the recognition of the object by the motion recognition probe on the right side), the timer starts to count for the third time when the motion recognition probe on the right side recognizes the occlusion by the object, obtaining the shielded time length t3 (the third time is from the beginning of the detection of the left motion recognition probe by the object shielding to the end of the restoration of the left motion recognition probe to the end of the non-shielding by the object shielding), if the conditions that the t1 is more than or equal to 10ms and less than or equal to 500ms and the 200ms is more than or equal to delta t2 is more than or equal to 5000ms ANDt3 is more than or equal to 500ms are met, the MCU of the control circuit board judges that the current target motion is the hovering motion after waving from. The operation of swinging the hand backward from right to left is similar to the above determination, and is not described again.
Therefore, when a user wants to turn down a page from the current page, the user can swing the hand from the left action recognition probe to the right action recognition probe and suspend for a period of time, the control circuit board can count three times through the timer to obtain a first sheltered time length, a delay time length and a second sheltered time length, the first sheltered time length is within the second preset time length range, the delay time length is within the second preset time length range, the second sheltered time length is within the third preset time length range, the MCU of the control circuit board determines that the target action of the user is a hovering action after swinging the hand from left to right, and at the moment, the MCU can control the intelligent smoke exhaust ventilator to execute an instruction of turning down a page from the current page of the display screen. Of course, if the user wants to turn up a page from the current page, the user can swing the hand from the right motion recognition probe to the left motion recognition probe, at this time, the MCU of the control circuit board can determine the target motion of the user as a hover motion after swinging the hand from right to left as described above, and at this time, the MCU can control the intelligent range hood to execute a command of turning up a page from the current page of the display screen.
In a possible embodiment, the step a2 in the control method of the intelligent range hood can be further implemented as the following steps a26 and a 27.
In step a26, a third occluded period from occluded to unoccluded by the object detected by the motion recognition probe on one side is determined.
In step a27, when the third occluded duration is within a fourth preset duration range, identifying the target action as a hover action of the target location, where the hover action of the target location is a hover action of a first side location when the side is a first side, and the hover action of the target location is a hover action of a second side location when the side is a second side.
Here, taking the left side as an example, the third preset time range includes a time period of 500ms or more, and when the motion recognition probe on the left side recognizes that the object is occluded, the timer starts to count time to obtain a third occluded time period t4(t4 is a time period from when the motion recognition probe on the left side detects that the object is occluded to when the motion recognition probe returns to the unoccluded state again), and when t4 is equal to or more than 500ms, it is determined that the target motion of the user is the left-side hovering motion. The right-side hovering action is similar to the judgment, and is not described in detail. It should be noted that the duration in the third preset duration range is longer than the duration in the first preset duration range.
Therefore, when the user wants to reduce the air volume, the user can extend the hand to the left action recognition probe, the time length for shielding the left action recognition probe is within a fourth preset time length range, if the time length exceeds 500ms, the control circuit board can determine that the third shielded time length t4 from the shielding of an object to the non-shielding of the object, which is detected by the left action recognition probe, exceeds 500ms through the timer, within the fourth preset time length range, the MCU of the control circuit board determines the target action of the user as the left hovering action, and at the moment, the MCU can control the intelligent range hood to execute the instruction for reducing the air volume. Of course, if the user wants to increase the air volume, the user may extend the hand to the right motion recognition probe, and the time length for shielding the right motion recognition probe is within the fourth preset time length range, for example, exceeds 500 ms. The specific detection and control process of the control circuit board may be as described above, and will not be described in detail. At this moment, the MCU of the control circuit board can determine the target action of the user as the right hovering action, and at this moment, the MCU can control the intelligent range hood to execute the instruction for increasing the air volume.
