Description

Background
The wind sweeping function is an important function of many devices (such as air conditioners and fans), but if a wind sweeping component (such as a wind sweeping plate or a wind sweeping blade) is clamped by an object during the wind sweeping process of the device, the device is easy to malfunction. If the fingers of a person are accidentally stuck, the fingers can cause injury to the human body.
Taking an air conditioner as an example, at present, the prior art mainly utilizes a photoelectric switch to detect the hand clamping, and the principle is that the existence of an object is detected by utilizing the shielding or reflection of the detected object to a light beam, under the normal condition, the output of the photoelectric switch is changed by high and low levels, if the air outlet panel of the air conditioner stops by external force left and right in the moving process, the rack on the air outlet panel also stops moving, so that the output of the photoelectric switch is changed from the original high and low levels to continuous high levels or continuous low levels. If the time of lasting high level or lasting low level exceeds a certain time, the phenomenon that the air-out panel of the air conditioner has a hand clamping is determined, and then the motor is controlled to overturn, so that the hand clamping is prevented from continuing.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided an anti-pinch control method embodiment, it should be noted that the steps illustrated in the flowchart of the accompanying drawings may be implemented in a computer system, such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be executed in an order different than that illustrated herein.
Fig. 1 is a flowchart of a hand-pinching prevention control method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
and S102, detecting whether a target object moves to the position of the wind sweeping component or not when the wind sweeping component of the wind sweeping equipment is in a moving state.
Specifically, the wind sweeping device includes, but is not limited to, a device having a wind sweeping function, such as an air conditioner and a fan, and the wind sweeping component refers to a component that moves when the wind sweeping function is implemented on the wind sweeping device, and includes, but is not limited to, any form of a wind sweeping plate, a wind guide plate, a wind sweeping blade, and the like. The target object may be any object or human body (or a part of the human body, such as a receiver or a finger) that can enter the closable area of the wind sweeping member of the wind sweeping device.
It should be noted that, when the wind sweeping device sweeps the wind, the wind sweeping component on the wind sweeping device is in a moving state, and when the wind sweeping component is in a moving state, if the target object moves to the position where the wind sweeping component is located, the risk that the target object is pinched may occur, and especially when a child plays with the accessory, the risk that the target object is pinched is greater.
It is easy to note that, in general, when the wind sweeping device is in the wind sweeping state or in the shutdown reset state, the wind sweeping component on the wind sweeping device is in the moving state, so as to be an alternative embodiment, the anti-pinch control method provided by the present application can be applied to, but is not limited to, the wind sweeping device in the wind sweeping state and in the shutdown reset state.
Optionally, when the wind sweeping component of the wind sweeping device is in a moving state, detecting whether a target object moves to the position where the wind sweeping component is located includes any one of the following steps:
detecting whether a target object moves to the position of the wind sweeping component when the wind sweeping equipment is in a wind sweeping state; or
And in the resetting process of the wind sweeping component, detecting whether a target object moves to the position of the wind sweeping component.
As an alternative embodiment, when the wind sweeping component of the wind sweeping device is in a moving state (for example, the wind sweeping device is in a wind sweeping state, or is in a power-off reset state), whether a target object moves to a position where the wind sweeping component is located may be detected by a human body sensing sensor (for example, an infrared sensor) or a camera device. Alternatively, it may be determined whether the target object moves towards the position where the sweeping member is located by detecting the orientation of the target object, the speed of movement, and the change in distance from the sweeping device.
Step S104, when the target object is detected to move to the position of the wind sweeping component, the detection device is controlled to detect whether the target object moves to the closable area or not by adopting the detection signal of the first frequency, wherein the closable area is an area where a hand is clamped on the wind sweeping component, and when the target object is not detected to move to the position of the wind sweeping component, the detection device is controlled to detect whether the target object moves to the closable area or not by adopting the detection signal of the second frequency, and the first frequency is higher than the second frequency.
Specifically, the detection device may be a detection device arranged at the wind sweeping component on the wind sweeping device, for example, a photoelectric switch, for detecting whether the target object moves to a closable area of the wind sweeping component; the closable area may be an area where a target object on the wind sweeping component is pinched, for example, a gap area between the wind sweeping plates, and if the target object has entered the closable area of the wind sweeping component and a pinch has occurred, in order to prevent the pinch, the detecting device may be controlled to detect whether the target object has moved to the closable area of the wind sweeping component with a detection signal of the first frequency when detecting that the target object has moved to the position of the wind sweeping component; in the case where the movement of the target object to the position where the wind sweeping member is located is not detected, the detection means may be controlled to detect whether the target object moves to the closable region of the wind sweeping member with the detection signal of the second frequency.
Since the possibility that the target object is pinched when moving to the position where the wind sweeping member is located is higher than the possibility that the target object is pinched when moving to the position where the wind sweeping member is located, when the target object moves into the preset region, the control detecting device detects whether the target object moves to the closable region of the wind sweeping member at a high frequency, whereas, when the target object does not move to the preset region, the control detecting device detects whether the target object moves to the closable region of the wind sweeping member at a low frequency, where the preset region may be a safe region outside the closable region of the wind sweeping member, for example, may be a region within a range of 0.5m from the wind sweeping device. When the target object is detected to move towards the position where the wind sweeping component is located and the target object moves to the preset area, the wind sweeping component can be controlled to stop moving, and therefore the purpose of effective prevention is achieved.
And step S106, controlling the wind sweeping component to stop moving when the target object is detected to move to the closable area.
Specifically, whether the target object moves to the closable area is detected by a detection device (e.g., a photoelectric sensor) mounted on the wind sweeping device at the wind sweeping member, and if the target object is detected to move to the closable area of the wind sweeping member, the wind sweeping member is controlled to stop moving.
As can be seen from the above, in the above embodiments of the present application, when the wind sweeping component of the wind sweeping apparatus is in a moving state, it is detected whether the target object moves to the position of the wind sweeping component, if it is detected that the target object moves to the position of the wind sweeping component, the detection device is controlled to detect whether the target object moves to the closable area of the wind sweeping component at a high frequency, and when it is detected that the target object moves to the closable area, the wind sweeping component is controlled to stop moving The technical effect of the safety of the wind sweeping equipment is improved, and the technical problem that the hand clamping prevention detection of the wind sweeping equipment can only be applied to the condition that fingers are clamped and cannot be effectively prevented due to the fact that photoelectric switches are adopted in the prior art is solved.
In an alternative embodiment, the wind sweeping member is controlled to continue to move in the event that no movement of the target object to the closable area is detected.
Optionally, based on any optional embodiment, in the case that the target object is detected to move to the position where the wind sweeping component is located, the method may further include: detecting whether a target object moves to a preset area, wherein the preset area is an area outside a closable area of the wind sweeping component; controlling the wind sweeping component to stop moving when the target object is detected to move to the position where the wind sweeping component is located and the target object moves to a preset area; and controlling the wind sweeping component to continue moving under the condition that the target object is not detected to move towards the position of the wind sweeping component, or the target object moves towards the position of the wind sweeping component and does not reach the preset area.
Through the embodiment, the reliability of the detection of the wind sweeping equipment is further improved.
Taking a photoelectric switch on an air conditioner as an example, the current anti-pinch mode of the photoelectric switch on the air conditioner is as follows: when the air outlet panel of the air conditioner stops due to external force, the rack on the air outlet panel stops moving, and the output of the photoelectric switch changes from the original high level to the low level and then changes into continuous high level (or low level output). If the main chip detects a constant high level (or low level) for a certain time T1, if T1 is greater than a set value T0, it is determined that a pinching state occurs. At the moment, the motor rotates reversely, so that the phenomenon that the hands are clamped continuously and the human body is injured is prevented.
In the above embodiment of the application, the photoelectric switch and the human body sensing sensor (or the camera device) are combined, and when the human body sensing sensor (or the camera device) detects that a person approaches the wind sweeping equipment (detects that the target object moves to the position of the wind sweeping component and moves to the preset area), the high-frequency detection signal of the photoelectric switch is controlled to detect whether the hand clamping phenomenon occurs or not; when the human body induction sensor (or the camera device) does not detect that a person approaches the wind sweeping equipment (for example, the movement of the target object to the position of the wind sweeping component is not detected, or the movement of the target object to the position of the wind sweeping component is detected but the movement is not moved to a preset area), the photoelectric switch is controlled to detect whether the hand clamping phenomenon occurs or not by using a low-frequency detection signal.
For example, fig. 2 is a flowchart of a method for performing anti-pinch control when an optional wind sweeping device is in a wind sweeping state according to an embodiment of the present disclosure, and as shown in fig. 2, when the wind sweeping device (e.g., an air conditioner) is in a wind sweeping state (e.g., a left-right wind sweeping state), a sensor (or an image capturing device) is initialized to start detecting whether a person approaches. If a person is detected, the detection mode I is entered, the detection time of single hand clamping is shortened (for example, the detection time of the photoelectric switch is reduced from the original 1.5s to 1.2s), and after the detection time is shortened, the hand clamping pain is greatly reduced. If no person is detected, the detection mode II is entered (the sensitivity of the detection mode I is higher than that of the detection mode II), or the detection is carried out according to the original detection time (for example, the detection time of the photoelectric switch is kept to be 1.5 s).
Therefore, by utilizing photoelectric switch detection and combining human body approach recognition technology, when a person is near the air conditioner, the detection time of the photoelectric switch is shortened, the pain of clamping hands of the air sweeping component is relieved, and the safety of the air conditioner is improved. When people are not near the air conditioner, the photoelectric switch detection is still effective, and the fault that the moving part of the air conditioner cannot move due to interference of the detection structure can be detected.
Optionally, based on any one of the above optional embodiments, in a case that it is detected that the target object moves to a position where the wind sweeping component is located, and the target object moves to a preset area, controlling the wind sweeping component to stop moving includes the following steps:
step S302, judging whether the staying time of the target object in the preset area and not reaching the closable area exceeds a preset time length or not;
and step S304, controlling the wind sweeping component to continue moving under the condition that the target object stays in the preset area and the staying time of the target object not reaching the closable area exceeds the preset time length.
Specifically, in the above embodiment, if it is detected that the target object moves to the wind sweeping component and moves to the preset area, it is determined whether the staying time of the target object staying in the preset area but not reaching the closable area exceeds a preset duration, if the staying time exceeds the preset duration, there may be an object blocking in front of the scanning device or a sensor fails, and the wind sweeping component may be controlled to continue moving, where if the scanning device is currently in a wind sweeping state, the wind sweeping component is controlled to continue to sweep wind, and if the scanning device is in a shutdown state and the wind sweeping component is in a reset stage, the wind sweeping component is controlled to continue to reset, that is, to directly close.
Still taking the wind sweeping device shown in fig. 2 as an example, in a left wind sweeping state and a right wind sweeping state, if a human body sensor or a camera device detects a person, the wind sweeping is directly stopped or the first detection mode is entered, if a certain time T3 (for example, 10min) is exceeded and a person is continuously detected, it is considered that an object is blocked in front of the air conditioner or the sensor fails, the function is directly shielded, and the detection is performed again after the air conditioner is powered off and powered on.
Fig. 4 is a flowchart of a method for controlling anti-pinch when an optional air sweeping device is in a shutdown reset state according to an embodiment of the present application, and as shown in fig. 4, in a shutdown reset process of a scanning device (e.g., an air conditioner), if a person is detected to approach, the air sweeping component is controlled to stop moving (e.g., the air sweeping panel of the air conditioner is controlled not to close). When people walk away, the air sweeping component is controlled to continue to reset (for example, the air sweeping panel of the air conditioner is controlled to be closed), and the possibility of clamping hands is avoided. If a person is continuously detected for a certain time T3 (for example, 10min), it is determined that an object is blocked in front of the air conditioner or the sensor fails, and the door plate is directly closed.
According to the embodiment of the invention, the invention also provides a system embodiment for realizing the anti-pinch control method,
fig. 5 is a schematic view of a hand-pinching prevention control system according to an embodiment of the present invention, as shown in fig. 5, the system includes: a detection device 501 and a controller 503.
The detection device 501 is used for detecting whether a target object moves to the position of the wind sweeping component when the wind sweeping component of the wind sweeping device is in a moving state;
the controller 503 is connected to the detection device 501, and is configured to control the detection device to detect whether the target object moves to the closable area by using a detection signal of a first frequency when the target object is detected to move to the position where the wind sweeping component is located, and control the wind sweeping component to stop moving when the target object is detected to move to the closable area, where the closable area is an area where a hand is pinched on the wind sweeping component, and control the detection device to detect whether the target object moves to the closable area by using a detection signal of a second frequency when the target object is not detected to move to the position where the wind sweeping component is located, where the first frequency is higher than the second frequency.
Optionally, the detection device includes, but is not limited to, a human body sensing sensor (e.g., an infrared sensor) or a camera.
As can be seen from the above, in the above embodiments of the present application, when the wind sweeping component of the wind sweeping device is in a moving state, the detection device 501 detects whether the target object moves to the position of the wind sweeping component, the controller 503 controls the detection device to detect whether the target object moves to the closable area of the wind sweeping component at a high frequency when the target object moves to the position of the wind sweeping component, and controls the wind sweeping component to stop moving when the target object moves to the closable area, it is easy to notice that the detection device can be controlled to detect whether the target object moves to the wind sweeping component at a low frequency when the target object does not move to the position of the wind sweeping component, so as to achieve the purpose of controlling the wind sweeping component to move in advance before the target object reaches the closable area of the wind sweeping component to prevent the occurrence of the hand pinching phenomenon, therefore, the technical effects of reducing human body injury and improving the safety of the wind sweeping equipment are achieved, and the technical problem that in the prior art, the wind sweeping equipment is subjected to anti-pinch detection by adopting a photoelectric switch, and the technical problem that the wind sweeping equipment can only be applied to the condition that fingers are pinched and cannot be effectively prevented is solved.
