Detailed Description
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 some, not all, embodiments of the present invention. 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 embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict. The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
The knob switch described in this embodiment may be used for any device that is controlled by a switch, for example, a lamp, and the knob switch controls the lamp to generate gradual change of brightness and/or color, and is also applicable to other devices that need to be turned on and off, and an application scenario of the knob switch is not specifically limited herein.
Referring to fig. 1a and 1b, which are schematic structural diagrams of a knob-type switch according to an embodiment of the present invention, a switch 100 includes a base 10, a knob 20, a breathing lamp 30 and a control board 40, wherein the knob 20 and the breathing lamp 30 are disposed on one end surface of the base 10, the other end surface of the base 10 is mounted on a wall surface or a to-be-mounted surface such as a controller, and the control board 40 is disposed in the base 10, and the control board 40 is electrically connected to the knob 20 and the breathing lamp 30, respectively. The knob 20 can rotate clockwise or counterclockwise relative to the end face of the base 10, and the control board 40 can control the breathing lamp 30 to perform brightness gradation according to the rotation of the knob 20. It should be noted that the gradual brightness change of the breathing lamp 30 in the embodiment of the present invention includes gradual brightness increase or gradual brightness decrease of the breathing lamp 30.
It should be noted that the shapes of the base 10, the knob 20 and the breathing lamp 30 and the relative positional relationship therebetween can be adjusted according to the needs of the user, and the structural schematic diagram of the knob switch shown in the present embodiment is only an exemplary illustration, and is not limited to the shapes and the relative positional relationship thereof.
The control panel 40 is used for acquiring the rotation angle of the knob 20 and controlling the breathing lamp 30 to realize gradual brightness change according to the rotation angle. Specifically, the control board 40 includes an angle sensor 41, a processor 42 and a storage device 43, wherein the processor 42 is electrically connected to the angle sensor 41 and the storage device 43, respectively, it should be noted that the number of the processors 42 may be one or more, and in the present embodiment, as shown in fig. 1b, one is taken as an example for description. In other embodiments, the angle sensor 41 may be replaced by an encoder or other component capable of collecting an angle or angle-related variable.
In one embodiment, the angle sensor 41 is mounted on the rotary knob 20 and rotates clockwise or counterclockwise together with the rotary knob 20, and the angle sensor 41 collects the real-time rotation angle of the rotary knob 20. In this embodiment, the rotation angle output by the angle sensor 41 is accumulated according to the rotation direction of the knob 20, and when the angle sensor 41 rotates clockwise with the knob 20, the rotation angle currently output by the angle sensor 41 increases progressively on the basis of the previous rotation angle; when the angle sensor 41 rotates counterclockwise with the knob 20, the rotation angle currently output by the angle sensor 41 is decreased on the basis of the previous rotation angle. For example, when the knob 20 has rotated clockwise and the rotation angle output by the angle sensor 41 is +60 degrees, if the knob 20 rotates counterclockwise and the rotated angle is 5 degrees, the rotation angle currently output by the angle sensor 41 is decreased on the basis of the previous rotation angle of +60 degrees, i.e., the rotation angle currently output by the angle sensor 41 is +55 degrees. For another example, when the knob 20 has been rotated clockwise and the rotation angle output by the angle sensor 41 is +60 degrees, if the knob 20 continues to rotate clockwise and the rotated angle is 5 degrees, the rotation angle currently output by the angle sensor 41 is incremented on the basis of the last rotation angle of +60 degrees, i.e. the rotation angle currently output by the angle sensor 41 is +65 degrees. It should be noted that, when the user operation includes multiple operations and the time interval between two adjacent operations is smaller than the preset time threshold, the rotation angle value output by the angle sensor 41 is an accumulated value, and in this embodiment, the multiple operations are referred to as a rotation operation; otherwise, the processor 42 regards the first rotation operation of the two adjacent operations as the end of the wheel rotation operation, and refers to the second rotation operation of the two adjacent operations as a new rotation operation. In the present embodiment, when it is determined that the user operation is finished, that is, when the user performs a new rotation operation, the rotation angle value output by the angle sensor 41 is cleared.
In the present embodiment, the angle sensor 41 sends the output rotation angle to the processor 42, and the processor 42 obtains the control mode of the knob 20 according to the rotation angle, wherein the control mode includes the rotation angle generated by the angle sensor 41 when the knob 20 is rotated. In some embodiments, processor 42 also determines the current rotational direction of knob 20 based on the current rotational angle and the last one or more rotational angles. For example, if the current rotation angle is increased from the previous rotation angle, the current rotation direction of the knob 20 is clockwise; if the current rotation angle is decreased from the previous rotation angle, the current rotation direction of the knob 20 is counterclockwise.
The processor 42 is connected to the angle sensor 41, on one hand, and is configured to receive the rotation angle output by the angle sensor 41, on the other hand, the processor 42 is further electrically connected to the breathing lamp 30, and the processor 42 controls the brightness gradient of the breathing lamp 30 according to the rotation angle output by the angle sensor 41.
The memory device 43 is communicatively coupled to the one or more processors 42, and the one or more programs stored on the memory device 43 are executable by the one or more processors 42 to enable the one or more processors to perform an embodiment of a method of controlling a breathing lamp as described in any of the embodiments below.
In the embodiment of the invention, the rotation angle of the knob is acquired by the angle sensor, so that the processor can control the breathing lamp to gradually change the brightness according to the rotation angle, the user operation is associated with the brightness of the breathing lamp, the brightness of the breathing lamp gradually changes the brightness along with the user operation, and the user experience is improved.
Referring to fig. 2, an embodiment of the present invention provides a method for controlling a breathing lamp, which is applied to the knob switch, where the knob switch includes a knob and the breathing lamp, and the method includes:
s21, acquiring a control mode of the knob;
the control mode refers to a control mode of the breathing lamp formed by operating a knob by a user, wherein the control mode comprises a rotation angle generated when the knob is rotated. It should be noted that the rotation angle output by the angle sensor is an angle rotated by the user through one or more continuous operations of the knob, wherein when the user performs multiple continuous operations, and the time interval between any two adjacent operations is smaller than a preset time threshold, the user can be regarded as one rotation operation.
The user operation knob can rotate clockwise or anticlockwise relative to the switch base, and when the operation knob rotates clockwise, the rotating angle is increased progressively on the basis of the rotating angle of the last output; when the direction of the operation knob is counterclockwise rotation, the rotation angle is decreased on the basis of the rotation angle of the last output.
In some embodiments, the difference between the currently output rotation angle and the last output rotation angle may be used to determine the rotation direction of the user operation knob. For example, the currently output rotation angle is +60 degrees, the last output rotation angle is +55 degrees, and the difference between the two rotation angles is +5 degrees, so that the current direction in which the user operates the knob is clockwise rotation of the knob. For another example, the currently output rotation angle is +60 degrees, the last output rotation angle is +65 degrees, and the difference between the two rotation angles is-5 degrees, so that the current direction in which the user operates the knob is to rotate the knob counterclockwise.
S23, determining a brightness control function of the breathing lamp according to the control mode, wherein the brightness control function is related to the rotation angle of the control mode;
the brightness control function is used for controlling the rule of brightness gradual change of the breathing lamp, wherein the brightness gradual change specifically refers to gradual brightness increase or gradual brightness decrease. In this embodiment, the brightness control of the breathing lamp is associated with the user operation, the user operation is specifically embodied as the direction and the rotation speed of the knob rotated by the user, the rotation speed is directly embodied as the change of the rotation angle, the faster the change of the rotation angle is, the faster the speed of controlling the brightness gradual change of the breathing lamp is, and conversely, the slower the change of the rotation angle is, the slower the speed of controlling the brightness gradual change of the breathing lamp is, so that the brightness change of the breathing lamp can follow the user operation, and the user experience is improved. For example, when the user slowly operates the knob, then the breathing lamp performs brightness gradation according to the slow operation speed of the user; when the user quickly operates the knob, then, the breathing lamp quickly changes the brightness gradually according to the operation speed of the user.
In some embodiments, the control mode further comprises a first operation and/or a second operation, wherein the first operation is for instructing to rotate the knob clockwise and the second operation is for instructing to rotate the knob counterclockwise. Then, step S23 includes:
s231, determining a brightness control function of the breathing lamp according to the rotation angle generated by the first operation and/or the second operation.
It will be appreciated that the user operation may be embodied to include only the first operation, only the second operation, or both the first and second operations. According to the characteristic that the angle sensor outputs the rotation angle value, when the knob rotates clockwise, the angle value which is sensed by the angle sensor to rotate is a positive value, and when the knob rotates anticlockwise, the angle value which is sensed by the angle sensor to rotate is a negative value, so that when the user operation includes the first operation and the second operation, and the time interval between the first operation and the second operation is less than the preset time threshold, the rotation angle output by the angle sensor represents the accumulated value of the rotation angle during the first operation and the rotation angle during the second operation which are sensed by the angle sensor. For example, if the knob is rotated by +60 degrees in the first operation and-30 degrees in the second operation, the final rotation angle according to the first operation and/or the second operation is +30 degrees. The angular change of the angle of rotation is then used to determine a brightness control function of the breathing lamp.
In this embodiment, the user operation is subdivided, and may be embodied as only including the first operation, only including the second operation, or including both the first operation and the second operation, and the rotation angle generated by the user operation is used to determine the brightness control function of the breathing lamp, so that the brightness control manner of the breathing lamp is enriched.
And S25, controlling the brightness of the breathing lamp according to the brightness control function and the rotation angle.
In the embodiment, the brightness control function is divided into a brightness gradually-increasing control function and a brightness gradually-decreasing control function according to the gradual brightness change of the breathing lamp, wherein the brightness gradually-increasing control function is used for controlling the brightness of the breathing lamp to gradually increase along with the increase of the rotation angle, and the brightness gradually-decreasing control function is used for controlling the brightness of the breathing lamp to gradually decrease until the lowest brightness of the breathing lamp.
In the embodiment of the invention, the control mode of the knob is obtained, the brightness control function of the breathing lamp is determined according to the control mode, so that the brightness of the breathing lamp is controlled according to the brightness control function and the rotation angle of the control mode, and further, the user operation is associated with the brightness of the breathing lamp, so that the brightness of the breathing lamp is gradually changed in brightness along with the user operation, and the user experience is improved.
Referring to fig. 3a, when the control mode includes the first operation, the determining the brightness control function of the breathing lamp according to the rotation angle generated by the first operation and/or the second operation includes:
s31, determining a gradually-lighting control function of the breathing lamp according to the first rotation angle;
the first rotation angle is generated during the first operation, and the fade-in control function is used for controlling the brightness of the breathing lamp to gradually increase along with the increase of the first rotation angle within a certain angle range.
The first operation is used for instructing the knob to rotate clockwise, and it can be understood that the brightness of the breathing lamp cannot rise infinitely, and an excessive working current burns out the breathing lamp to cause the breathing lamp to work normally, so in this embodiment, a first angle threshold is predefined, and when a first rotation angle of the knob is smaller than the first angle threshold, the brightness of the breathing lamp is controlled to gradually rise as the first rotation angle becomes larger; when the first rotation angle of the knob is equal to the first angle threshold value, the brightness of the breathing lamp reaches the maximum brightness; when the first rotation angle of the knob is larger than the first angle threshold, the brightness of the breathing lamp does not gradually rise along with the increase of the first rotation angle, and the brightness stays at the maximum brightness all the time. Preferably, the first angle threshold is 180 degrees. It should be noted that the first angle threshold may be customized according to the product requirement, and the numerical value of the first angle threshold is not specifically limited herein.
To improve the comfort of the user, in some embodiments, the fade-in control function is a sinusoidal function. Specifically, referring to fig. 3b, the brightness of the breathing lamp can be controlled to change with the rotation angle in unit time according to the following fade-in control function:
where ω is the rotation angular velocity (the rotation of the user is considered to be similar to a uniform rotation), LmaxIs the maximum brightness, L, of the breathing lamp0Brightness, T, of the breathing lamp at the beginning of said first operationdelThe preset delay time of the breathing lamp relative to the rotation action is greater than or equal to 0. In one embodiment, TdelSet to 0.5 s. In addition, L is0Greater than or equal to LminWhen the rotation angle of the knob is changed from 0 degree, L0＝Lmin。
As shown in FIG. 3b, the brightness of the breathing lamp reaches LmaxTime, i.e. t corresponding to the time axis1When the position is determined, if the first rotation angle is greater than or equal to the first angle threshold, the fade-up control function is:
f(t)＝Lmax，t≥α1/ω+Tdel
wherein L ismaxIs the maximum brightness, alpha, of the breathing lamp1Is a predetermined first angle threshold, TdelA preset delay time for the breathing light relative to the rotational movement. At this time, the breathing lamp will not control the brightness of the breathing lamp to rise according to the user operation, but maintain the brightness of the breathing lamp at the maximum brightness.
In some embodiments, when the first operation ends, the method further comprises:
s33, acquiring a stop signal of the first operation, wherein the stop signal of the first operation is used for indicating that the clockwise rotation of the knob is stopped;
before the stop signal of the first operation is acquired, the processor continues to sample the first rotation angle according to a preset sampling rate, and if the first rotation angle is not sampled within a preset sampling time threshold value and is changed, the stop signal of the first operation is generated.
In the present embodiment, when the stop signal of the first operation is generated, the angle sensor is reset, and the first rotation angle output is set to 0 degrees.
S35, determining a first dimming control function of the breathing lamp according to the stop signal of the first operation;
wherein the first dimming control function is used for controlling the brightness of the breathing lamp to gradually decrease until the lowest brightness of the breathing lamp.
In some embodiments, the first dimming control function is a cosine function. Specifically, referring to fig. 3c, the brightness of the breathing lamp is controlled to gradually decrease according to the following first dimming control function:
wherein,
Lαfor the brightness of the breathing lamp at the time of receiving the stop signal of the second operation, TαIs the stop time of the second operation, TdimFor controlling the brightness of the breathing lamp from LmaxTo LminThe preset light-off time. In addition, L isαLess than or equal to LmaxWhen the rotation angle of the knob is greater than the angle threshold, Lα＝Lmax。LminThe minimum brightness of the breathing lamp is generally not 0, because when the knob switch is connected to the circuit, the indicator lamp has a minimum brightness and is not completely dark, and only when the circuit is switched off, the indicator lamp is not powered on and is completely dark.
In the embodiment of the invention, the first rotation angle during the first operation of the user is associated with the dimming control function of the breathing lamp, and after the operation is stopped, the brightness of the breathing lamp is controlled to be gradually dimmed according to the dimming control function within the preset time, so that the brightness of the breathing lamp is gradually changed along with the operation of the user, and the brightness of the breathing lamp is controlled to be gradually dimmed after the operation of the user is finished, so that the brightness change occurs again along with the operation of the user next time, and the use experience of the user is improved.
In still other embodiments, when the control mode includes the second operation, referring to fig. 4a, the determining the brightness control function of the breathing lamp according to the rotation angle generated by the first operation and/or the second operation includes:
s41, linearly adjusting the brightness of the breathing lamp to the highest brightness within a preset lamp-on time;
and S42, determining a second dimming control function of the breathing lamp according to the second rotation angle.
The second rotation angle is generated during the second operation, and the second dimming control function is used for controlling the brightness of the breathing lamp to gradually decrease as the second rotation angle becomes larger (where larger means that the absolute value of the second rotation angle becomes larger) until the lowest brightness of the breathing lamp.
In some embodiments, the second dimming control function is a cosine function, and in particular, referring to fig. 4b, the brightness of the breathing lamp is controlled to gradually decrease according to the following second dimming control function:
where ω is a rotational angular velocity of the second operation, LmaxIs the maximum brightness, L, of the breathing lampminIs the minimum brightness, T, of the breathing lampdelThe delay time of the breathing lamp relative to the rotation action is preset.
Please refer to FIG. 4b, when the brightness of the breathing lamp reaches LminAt this time, if the second rotation angle is greater than or equal to a second angle threshold, the second dimming control function of the breathing lamp is:
wherein alpha is2The second angle threshold is preset. At this time, the breathing lamp will not control the brightness of the breathing lamp to decrease according to the user operation, but maintain the brightness of the breathing lamp at the minimum brightness. In the present embodiment, the method for calculating the rotation angle output from the angle sensor described above is used to calculate the rotation angleThe second rotation angle is obtained when rotating counterclockwise, and the rotation angle of the angle sensor output is decreased on the basis of the previous rotation angle at the counterclockwise rotation, so that the value of the second rotation angle is a negative value. Then, the second rotation angle being greater than or equal to a second angle threshold means that the absolute value of the second rotation angle is greater than or equal to the second angle threshold.
It should be noted that, in the present embodiment, the first angle threshold and the second angle threshold may be set to the same angle value, such as 180 degrees.
In still other embodiments, when the second operation is stopped and the brightness of the breathing lamp does not reach a minimum brightness, the method further comprises:
s43, acquiring a stop signal of the second operation, wherein the stop signal is used for indicating that the knob stops rotating anticlockwise;
the processor continues to sample the second rotation angle according to a preset sampling rate before obtaining the stop signal of the second operation, which is the same as the stop signal of the first operation, and generates the stop signal of the second operation if the second rotation angle is not sampled to be changed within a preset sampling time threshold.
In the present embodiment, when the stop signal of the second operation is generated, the angle sensor is reset, and the second rotation angle output is set to 0 degrees.
And S44, determining a first dimming control function of the breathing lamp according to the stop signal of the second operation, wherein the first dimming control function is used for controlling the brightness of the breathing lamp to gradually decrease.
Specifically, please refer to the brightness change of the breathing lamp shown in fig. 4c, during the second operation of the user, the brightness of the breathing lamp is controlled to gradually decrease according to the second dimming control function until the stop signal of the second operation is obtained; when a stop signal of a second operation is acquired, the brightness of the breathing lamp is controlled to gradually decrease until the lowest brightness of the breathing lamp according to a first dimming control function.
In some embodiments, the first dimming control function is a cosine function. Specifically, referring to fig. 3c, the brightness of the breathing lamp is controlled to gradually decrease according to the following first dimming control function:
wherein,
Lαfor the brightness of the breathing lamp at the time of receiving the stop signal of the second operation, TαTime of the second operation, TdimFor controlling the brightness of the breathing lamp from LmaxTo LminThe preset light-off time. In addition, L isαLess than or equal to LmaxWhen the rotation angle of the knob is greater than the angle threshold, Lα＝Lmax。
In the embodiment of the invention, the second rotation angle during the second operation of the user is associated with the dimming control function of the breathing lamp, so that the brightness gradient of the breathing lamp is changed along with the change of the operation of the user.
When the control mode includes at least one first operation and at least one second operation, or includes at least two first operations, or includes at least two second operations, in this embodiment, when the time interval between any two adjacent operations is greater than or equal to the preset time interval threshold, then the two operations are defined as two independent and unrelated rotation operations, and the breathing lamp controls the brightness gradient of the breathing lamp according to the first rotation operation and the second rotation operation respectively; and when the time interval between any two adjacent operations is smaller than a preset time interval threshold value, regarding the operations as the same rotation operation.
Thus, in some embodiments, referring to fig. 5a, when a time interval between two adjacent operations is smaller than a preset time interval threshold, the determining the brightness control function of the breathing lamp according to the rotation angle generated by the first operation and/or the second operation includes:
s51, acquiring a rotation angle generated in the (N + 1) th operation;
s52, determining a brightness control function of the breathing lamp according to the rotation angle generated in the (N + 1) th operation, so as to control the brightness of the breathing lamp in the time interval of the (N + 1) th operation and the (N + 2) th operation, wherein N is an integer greater than or equal to 0.
It can be understood that when the required rotation angle is large, the user may not rotate the breathing lamp to the position at one time, a slight pause may occur in the rotation process, and the brightness control function controls the brightness change of the breathing lamp according to the change of the rotation angle, however, in the time interval between the N +1 operation and the N +2 operation, the brightness of the breathing lamp is kept unchanged in the time interval because the rotation angle is not changed.
