Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of an identification method for detecting a manipulation of a magnetic attraction control button according to the present application. The execution main body of the identification method for detecting the control of the magnetic attraction control button is a magnetic attraction touch panel.
Referring to fig. 2, the magnetic touch panel 1000 includes a touch substrate 1100, a plurality of gear/function sensing electrodes 1200, a storage device 1300 and a processing device 1400, wherein the plurality of gear/function sensing electrodes 1200 are disposed on the same side of the touch substrate 1100, and at the same time, a side of the touch substrate 1100 where the plurality of gear/function sensing electrodes 1200 are not disposed is used for placing a magnetic attraction control button 2000.
The magnetic control knob 2000 is adsorbed on the touch substrate 1100 in a magnetic manner, so that the touch substrate 1100 is not required to be grooved, related control can be realized by the magnetic control knob 2000, the magnetic control knob is attractive and practical, and waterproof is realized, and when accumulated greasy dirt is required to be cleaned, the magnetic control knob 2000 can be directly taken away from the touch substrate 1100, so that the magnetic control knob is attractive to the greatest extent, and better use experience is brought to a user.
Referring to fig. 3, the magnetic attraction control knob 2000 includes a gear/function selection sensing block 2110, wherein the material of the gear/function selection sensing block 2110 is metal, and the gear/function selection sensing block 2110 corresponds to a plurality of gear/function sensing electrodes 1200.
Specifically, the plurality of gear/function sensing electrodes 1200 in the magnetic touch panel 1000 are used for sensing the operation on the gear/function selection sensing block 2110 in the magnetic control knob 2000 to generate corresponding sensing values, and meanwhile, the plurality of gear/function sensing electrodes 1200 correspond to different gears or different execution functions, when the user operates the magnetic control knob 2000 to change the position of the gear/function selection sensing block 2110, the target gear/function sensing electrode 1200 is selected, thereby realizing the selection of functions or gears.
The magnetic attraction control knob 2000 of the present application is operated by changing the position of the gear/function selection sensing block 2110 after the user contacts with the gear/function selection sensing block 2110, and the whole working principle is to use the capacitive sensing effect between the gear/function selection sensing block 2110 and the gear/function sensing electrode 1200.
The memory device 1300 stores a program, and the processing device 1400 connects the memory device 1300 and the plurality of gear/function sensing electrodes 1200 to retrieve the program stored in the memory device 1300 to execute the identification method for detecting the manipulation of the magnetic attraction control button according to the present application.
With continued reference to fig. 1, the identification method includes:
S110, detecting the sensing values of the plurality of gear/function sensing electrodes 1200 to determine whether at least one sensing value of the gear/function sensing electrodes 1200 changes to a first direction or a second direction more than a first threshold.
And S120, when the sensing value of the at least one gear/function sensing electrode 1200 is determined to change to be larger than a first threshold value in a first direction or a second direction, corresponding identification instructions are generated, wherein the identification instructions comprise a first identification instruction for indicating that the magnetic attraction control button 2000 is placed on the magnetic attraction touch panel 1000 and/or a second identification instruction for indicating that the magnetic attraction control button 2000 is taken away from the magnetic attraction touch panel 1000.
When the magnetic manipulation knob 2000 is placed on the magnetic touch panel 1000, the sensing value of at least one of the gear/function sensing electrodes 1200 may change more than the first threshold in one direction due to the capacitive sensing effect between the gear/function selection sensing block 2110 and the gear/function sensing electrode 1200, and a sudden change may be formed compared to when the magnetic manipulation knob 2000 is not placed, and when the magnetic manipulation knob 2000 is removed from the magnetic touch panel 1000, the sensing value of at least one of the gear/function sensing electrodes 1200 may also change more than the first threshold in one direction due to the capacitive sensing effect, and a sudden change may also be formed compared to when the magnetic manipulation knob 2000 is placed on the magnetic touch panel 1000.
In the above embodiment, the state of the magnetic attraction control knob 2000 can be determined based on the capacitance sensing effect by using the change condition of the sensing value of the at least one gear/function sensing electrode 1200 to determine whether the magnetic attraction control knob 2000 is placed on the magnetic attraction touch panel 1000 or removed from the magnetic attraction touch panel 1000, so that the additional cost is avoided.
In the present embodiment, the first recognition instruction is generated when it is determined that the sensed value of the at least one shift position/function sensing electrode 1200 is changed to be greater than the first threshold value in the first direction, or the second recognition instruction is generated when it is determined that the sensed value of the at least one shift position/function sensing electrode 1200 is changed to be greater than the first threshold value in the second direction.
It can be understood that, when the magnetic control knob 2000 is placed on the magnetic touch panel 1000, the direction of the change of the sensing value generated by the gear/function sensing electrode 1200 is opposite to the direction of the change of the sensing value generated when the magnetic control knob 2000 is removed, and see fig. 4 and 5.
Therefore, in an application scenario, when the magnetic attraction control knob 2000 is set to be placed, the direction of the change of the sensing value generated by the at least one gear/function sensing electrode 1200 is a positive direction, and when the magnetic attraction control knob 2000 is taken away, the direction of the change of the sensing value generated by the at least one gear/function sensing electrode 1200 is a negative direction.
That is, in this application scenario, the first direction is a positive direction, that is, when the amount of increase in the sensing value of the at least one gear/function sensing electrode 1200 is greater than the first threshold, a first recognition instruction is generated that instructs the magnetic attraction control knob 2000 to be placed on the magnetic attraction touch panel 1000, and the second direction is a negative direction, that is, when the amount of decrease in the sensing value of the at least one gear/function sensing electrode 1200 is greater than the first threshold, a second recognition instruction is generated that instructs the magnetic attraction control knob 2000 to be taken away from the magnetic attraction touch panel 1000.
In this embodiment, referring to fig. 4 and 5, step S110 further specifically includes detecting the sensing values of the plurality of gear/function sensing electrodes 1200 to determine whether there is a change in the sensing values of the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220 in the first direction or the second direction that is greater than the first threshold, where the first gear/function sensing electrode 1210 is adjacent to the second gear/function sensing electrode 1220, and the projection of the gear/function selecting sensing block 2110 on the magnetic touch panel 1000 at least partially overlaps the area between the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220 when the magnetic attraction control knob 2000 is placed on the magnetic touch panel 1000.
Specifically, when the magnetic attraction control knob 2000 is placed on the magnetic attraction touch panel 1000, the gear/function selection sensing block 2110 is placed adjacent to two adjacent gear/function sensing electrodes 1200 at the same time with a high probability, and when the magnetic attraction control knob 2000 is placed on the magnetic attraction touch panel 1000, the projection of the gear/function selection sensing block 2110 on the adjacent first gear/function sensing electrode 1210 and second gear/function sensing electrode 1220 is entirely between the adjacent first gear/function sensing electrode 1210 and second gear/function sensing electrode 1220, and when the magnetic attraction control knob 2000 is removed, the sensing value of the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220 is changed to be larger than the first threshold value, and therefore, the sensing value of the adjacent first gear/function sensing electrode 1210 and second gear/function sensing electrode 1220 is determined to be accurately controlled by the sensed state of the adjacent first gear/function sensing electrode 1210 and the adjacent second gear/function sensing electrode 1220 for the recognition.
The closer the gear/function sensing electrode 1200 is to the gear/function selecting sensing block 2110, the larger the amount of change in the sensing value, for example, in the application scenario of fig. 4 and 5, the closer the first gear/function sensing electrode 1210 is to the gear/function selecting sensing block 2110 than the second gear/function sensing electrode 1220, so that the amount of change in the sensing value on the first gear/function sensing electrode 1210 is greater than the amount of change in the sensing value on the second gear/function sensing electrode 1220 when the magnetic attraction control knob 2000 is placed or removed.
Meanwhile, in the application scenario of fig. 4 and 5, when the magnetic attraction control knob 2000 is placed or removed, the sensing values of the rest of the gear/function sensing electrodes 1200 except the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220 are changed in the first direction or the second direction, but the change is not large, and the first threshold value is not exceeded.
In other embodiments, when it is ensured that the magnetic control knob 2000 is placed on the magnetic touch panel 1000, the gear/function selecting sensing block 2110 is opposite to one gear/function sensing electrode 1200, and step S110 may specifically be detecting the sensing values of the plurality of gear/function sensing electrodes 1200 to determine whether there is a change of the sensing value of one gear/function sensing electrode 1200 in the first direction or the second direction, which is greater than the first threshold.
In this embodiment, the first threshold exceeds 20% or more of the background noise.
Specifically, when the user manipulates the magnetic attraction control knob 2000 to perform gear/function selection, the sensing value generated by the selected gear/function sensing electrode 1200 may change, but the sensing value generated by the unselected gear/function sensing electrode 1200 may also change, but the amount of change does not exceed the amount of change generated by the selected gear/function sensing electrode 1200, that is, when the user performs gear/function selection, the amount of change of the sensing value generated by the selected gear/function sensing electrode 1200 is the largest, but there is an upper limit defined as the upper limit, that is, the lower limit is the maximum amount of change of the sensing value generated by the selected gear/function sensing electrode 1200 when the user manipulates the magnetic attraction control knob 2000 to perform gear/function selection.
In this embodiment, however, the reason why the sensing value of the at least one gear/function sensing electrode 1200 is changed to be greater than the first threshold in the first direction or the second direction is that the user operates the magnetic attraction control knob 2000 to select the gear/function, so that the first threshold is set to be greater than 20% of the background noise, for example, the first threshold is set to be greater than 20%, 30% or 40% of the background noise.
In this embodiment, the identification method further includes:
s130, detecting the sensing value of the auxiliary function sensing electrode 1500 to determine whether the sensing value is changed in the first direction or the second direction more than the second threshold.
And S140, when the sensing value of the auxiliary function sensing electrode 1500 is determined to change to be larger than a second threshold value in the first direction or the second direction, corresponding auxiliary identification instructions are generated, wherein the auxiliary identification instructions comprise a first auxiliary identification instruction for indicating that the magnetic attraction control button 2000 is placed on the magnetic attraction touch panel 1000 and/or a second auxiliary identification instruction for indicating that the magnetic attraction control button 2000 is taken away from the magnetic attraction touch panel 1000.
In one embodiment, as shown in fig. 3, the magnetic attraction control knob 2000 includes an auxiliary key 2200 in addition to the gear/function selection sensing block 2110, and the magnetic attraction control knob 2000 further includes a conductive ring 2100, a first magnetic member 2300, a first insulating ring 2400, and a second insulating ring 2500.
The gear/function selecting sensor 2110 is convexly disposed on an inner wall of the conductive ring 2100 and is connected with the conductive ring 2100, the conductive ring 2100 is made of a conductive material, for example, metal, in an application scenario, the gear/function selecting sensor 2110 and the conductive ring 2100 are integrally formed, the auxiliary key 2200 includes a cap 2210 and a rod 2220 convexly disposed on the cap 2210, the cap 2210 is used for contacting with a hand of a user, the rod 2220 sequentially passes through the first insulating ring 2400, the conductive ring 2100 and the second insulating ring 2500 to contact with the touch substrate 1100, specifically, an end surface of the rod 2220 far from the cap 2210 contacts with the touch substrate 1100, and meanwhile, the rod 2220 is of a hollow structure, which is provided with a groove (not shown in the figure), the first magnetic member 2300 is accommodated in the groove, the second magnetic member (not shown in the figure) in the first magnetic member 2300 and the magnetic touch panel 1000 are attracted to each other, so that the magnetic knob 2000 is adsorbed on the touch substrate 1100, and the first insulating ring 2400 and the second insulating ring 2500 are used for isolating the conductive ring 2500 and the auxiliary key 2100.
The first magnetic element 2300 in the magnetic actuation button 2000 and the second magnetic element in the magnetic actuation touch panel 1000 may be a pair of magnets that attract each other, or one may be a magnet, and the other may be a metal element that can be attracted by a magnet.
Referring to fig. 2, corresponding to the auxiliary key 2200 in the magnetic control knob 2000, there is an auxiliary function sensing electrode 1500 in the magnetic touch panel 1000, and the auxiliary function sensing electrode 1500 and the gear/function sensing electrode 1200 are located on the same side of the touch substrate 1100, for sensing the control on the auxiliary key 2200 in the magnetic control knob 2000 to generate a corresponding sensing value.
In an application scenario, in the magnetic attraction control knob 2000 of fig. 3, the user first changes the state of the gear/function selection sensing block 2110 by rotating the conductive ring 2100, so as to select the plurality of gear/function sensing electrodes 1200, and after the user selects the gear/function, the user confirms by touching the auxiliary key 2200, and then the device adjusts the corresponding gear/function, that is, the auxiliary key 2200 is the confirmation key, and the user confirms by manipulating the auxiliary key 2200, specifically, when the user manipulates the auxiliary key 2200, the auxiliary function sensing electrode 1500 is triggered, and then generates the corresponding confirmation identification command.
In another application scenario, the user may also perform operations such as cancel, pause, etc. by manipulating the auxiliary key 2200, for example, when the device is running, the user may pause the device by manipulating the auxiliary key 2200, or after the user performs selection of a gear or function, the user may cancel the previous selection of the gear or function by manipulating the auxiliary key 2200.
In summary, the present application is not limited with respect to the function of the auxiliary key 2200.
In contrast, when the auxiliary function sensing electrode 1500 is placed or removed from the magnetic attraction control knob 2000, as shown in fig. 6 and 7, the change amount of the sensing value on the auxiliary function sensing electrode 1500 is a fixed value due to the capacitive sensing effect between the auxiliary function sensing electrode 1500 and the auxiliary key 2200, so that the embodiment utilizes the change amount of the sensing value of the auxiliary function sensing electrode 1500 to perform auxiliary identification, and can avoid that the sensing value of the at least one gear/function sensing electrode 1200 changes to be larger than the first threshold in the first direction or the second direction, which is not caused by the fact that the magnetic attraction control knob 2000 is placed or removed, but is caused by the interference of external factors (such as oil stain generated on the magnetic attraction control knob 2000), thereby ensuring the accuracy of identification.
In the present embodiment, the first auxiliary command is generated when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes more than the second threshold in the first direction, or the second auxiliary command is generated when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes more than the second threshold in the second direction.
The direction of change of the sensing value of the auxiliary function sensing electrode 1500 is opposite to that of the gear/function sensing electrode 1200 when the magnetic attraction control knob 2000 is placed and removed.
In this embodiment, the second threshold value is equal to the first threshold value. In other embodiments, the second threshold may be unequal to the first threshold, which is not limited herein.
