Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
It is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
In order to solve the technical problem that holes need to be formed in the screen of the terminal device due to the fact that the infrared distance sensor is used in the current terminal device, and therefore the screen occupation ratio of the terminal device is reduced, the invention provides a technical scheme for sensing a proximity event based on a sensing metal sheet.
Before explaining the distance sensing processing method of the terminal device according to the embodiment of the present invention, in order to facilitate those skilled in the art to more clearly understand the terminal device according to the embodiment of the present invention, first, a structure of the terminal device according to the embodiment of the present invention is explained, and the following description is made:
in the embodiment of the present invention, the terminal device includes a capacitance sensing chip and multiple metal sheets for suspension processing, where at least one metal sheet is connected to the capacitance sensing chip to form a sensing metal sheet, and the multiple metal sheets for suspension processing may be of different hardware types, for example, may be one or more of a metal mesh enclosure of an earpiece suspended inside the terminal device, an antenna metal radiation sheet (e.g., a metal frame of the terminal device) suspended inside a frame of the terminal device, and an FPC cable suspended inside the frame of the terminal device.
Wherein, it is difficult to understand that, the sheetmetal of many places suspension processing mentioned above all need not all be at the openly trompil setting of terminal equipment casing, has reduced the black limit on the terminal equipment and has taken up the ratio, helps the screen of terminal equipment to take up the improvement of ratio, for example, when the sheetmetal of many places suspension processing includes the metal screen panel of earphone, can satisfy the design demand that the high screen took up the ratio through the size of the metal screen panel of control earphone. In addition, the above-mentioned metal sheets subjected to suspension processing at multiple positions are all hardware inherent to the device on the terminal, in this embodiment, by multiplexing these hardware, occupation of an internal accommodating space of the terminal device is further avoided, and it is helpful to improve function implementation of other hardware, for example, for an antenna, a signal of the antenna is affected when the antenna is arranged relatively close to an infrared distance sensor.
Next, a distance sensing processing method of the terminal device is described, wherein the execution subject of the method may be the above-mentioned capacitance sensing chip, and the capacitance sensing chip is used as a processor to execute the method of the embodiment.
Specifically, fig. 1 is a schematic flow chart of a distance sensing processing method for a terminal device according to an embodiment of the present invention, where the method includes the following steps:
It can be understood that after at least one metal sheet is connected with the capacitance sensing chip to form a sensing metal sheet, the change of the capacitance of each sensing metal sheet reflects the proximity of other objects and the like. This is because the capacitance of the sensing metal piece increases as other objects approach. Therefore, in the present embodiment, whether the capacitance value of each sensing metal sheet changes is monitored, so as to determine the proximity of an external object and the like.
However, the change in capacitance can be manifested by its own capacitance value and mutual capacitance value with other sensing metal sheets. Therefore, as a possible implementation manner, whether the capacitance value between each sensing metal sheet and the ground changes or not can be monitored, that is, the change of the capacitance value of each sensing metal sheet per se is monitored, so that the approach condition of the object is determined according to the change of the capacitance value of each sensing metal sheet per se;
as another possible implementation manner, whether the mutual capacitance value between each sensing metal sheet and each adjacent sensing metal sheet changes is monitored, because when an object approaches a certain sensing metal sheet, the capacitance value of the object itself changes, and the mutual capacitance value between the adjacent sensing metal sheets also necessarily changes, that is, the approach condition of the object is determined according to the change between the mutual capacitance values between the adjacent sensing metal sheets.
And 102, if the target induction metal sheet with the capacitance value changing exists, determining a medium and a distance close to the target induction metal sheet according to the capacitance value changing of the target induction metal sheet.
Specifically, as analyzed above, the capacitance value may represent the approach of the object, and therefore, if it is known that there exists the target sensing metal piece with the capacitance value changing, since the capacitance value represents the approach condition of the object, for example, a medium (for example, the approach of the metal medium and the approach of the human body represent different capacitance values) and a distance (for example, the closer the object is, the higher the capacitance value is increased), and the like, the medium and the distance approaching the target sensing metal piece may be determined according to the capacitance value changing of the target sensing metal piece.
It should be noted that, in different application scenarios, the way of determining the medium and the distance approaching the target sensing metal sheet according to the capacitance value change of the target sensing metal sheet is different, and the following examples are illustrated:
example one:
in this example, as shown in fig. 2, the step 102 includes:
Specifically, because the medium of the object that is close is different, the influence to the change of target response sheetmetal's capacitance value can be different certainly, therefore, according to a large amount of experimental data calibration in advance when the medium that is close the object is the human body, corresponding first numerical value, wherein, in order to further improve the accuracy of judging, when setting up first numerical value, can also combine the material and the position of every response sheetmetal, set up different first numerical value to different response sheetmetals.
Therefore, when the capacitance value of the target induction metal sheet is increased by a value larger than a preset first value in unit time, the capacitance value of the target induction metal sheet is rapidly increased in a short time, and the change situation of the capacitance value is consistent with that when the object medium is a human body, so that the medium close to the target induction metal sheet is determined to be the human body.
Specifically, under the state that no object is close, each induction metal sheet has an initial capacitance value, in the actual execution process, when the object is close to the induction metal sheet, it is obvious that the capacitance value of the target induction metal sheet can change, the approach distance of the object is different, the capacitance change value relative to the initial capacitance value is different, and the corresponding real-time capacitance value is different.
Example two:
in this example, as shown in fig. 3, the step 102 includes:
Similarly, because the media of the approaching object are different, the influence on the change of the capacitance value of the target induction metal sheet is different, and therefore, a corresponding second numerical value is calibrated in advance according to a large amount of experimental data when the media of the approaching object is metal, wherein when the second numerical value is set, the material and the position of each induction metal sheet can be combined, and different second numerical values are set aiming at different induction metal sheets in order to further improve the accuracy of judgment.
Therefore, when the capacitance value of the target induction metal sheet is increased by a value larger than a preset second value in unit time, the capacitance value of the target induction metal sheet is rapidly increased in a short time, and the change situation of the capacitance value is consistent with that when the object medium is metal, so that the medium close to the target induction metal sheet is determined to be metal.
Specifically, under the state of no object approaching, each sensing metal sheet has an initial capacitance value, in the actual execution process, when an object approaches the sensing metal sheet, it is obvious that the capacitance value of the target sensing metal sheet changes, the approaching distance of the object is different, and the capacitance change value relative to the initial capacitance value is different, and the corresponding real-time capacitance value is different.
When the approaching medium is metal, because metal may affect a signal of the antenna, a radiation mode and efficiency of the antenna depend on a proximity degree with the metal, in this embodiment, in order to ensure performance of the antenna, if it is determined that a suspension position of the target induction metal sheet in the terminal device is an antenna metal radiation sheet inside the frame, it is monitored whether a proximity distance between the current metal and the target induction metal sheet is smaller than a preset threshold value, the preset threshold value is calibrated according to experimental data, and when the proximity distance is smaller than the preset threshold value, it is verified that the target induction metal sheet may affect the signal of the antenna, therefore, if it is known that the proximity distance is smaller than the preset threshold value, the corresponding tuning switch is controlled to perform antenna tuning on the antenna metal radiation sheet, where a mode of performing antenna tuning on the antenna metal radiation sheet based on the corresponding tuning switch may include impedance tuning, aperture tuning, and the like.
As a possible implementation manner, the number of the antenna metal radiating sheets is multiple, and some loss performance can be recovered through tuning between the antenna metal radiating sheets, that is, the corresponding tuning switch is controlled through antenna tuning to add the antenna metal radiating sheets to achieve more optimal performance in a wider frequency range, and influence brought by a target sensing metal sheet is compensated, where the number of the antenna radiating sheets that are accessed may be determined according to a difference between a threshold value and an approach distance when the approach distance is smaller than a preset threshold value, and the transmission power of the antenna may also be determined according to a difference between the threshold value and the approach distance when the approach distance is smaller than the preset threshold value.
Example three:
in this example, it is considered that when the medium approaching the object is different, the change of the capacitance value is different, and thus, capacitance values of a plurality of target sensing metal pieces are collected according to a preset sampling period, a capacitance value change curve is constructed according to the collected capacitance values, the capacitance value change curve is matched with a pre-stored approach curve and a pre-stored distance curve corresponding to different media, wherein, as shown in fig. 4, the abscissa in each curve is the approach distance from the target sensor (the approach curve corresponding to the medium a in the figure), and the ordinate is the capacitance value, and the medium and the distance approaching the target sensing metal piece are determined according to the curve successfully matched.
And 103, carrying out corresponding operation processing on the terminal equipment according to the suspension position, medium and distance of the target induction metal sheet in the terminal equipment.
Specifically, the terminal device is correspondingly processed according to the suspension position, medium and distance of the target induction metal sheet in the terminal device, wherein the corresponding processing modes are different according to different application scenes, for example, the processing modes comprise screen turning-off and screen lighting, induction animation display control and the like. As a possible implementation manner, when the medium close to the object is the human body described above with reference to fig. 2, if it is determined that the suspension position of the target sensing metal piece in the terminal device is the top, it is monitored whether the proximity distance to the target sensing metal piece is smaller than a preset threshold, the preset threshold may be calibrated according to a large amount of experimental data, if it is known that the proximity distance is smaller than the preset threshold, it indicates that a certain part of the human body is close to the terminal device, and in order to avoid a wrong operation, the terminal device is controlled to turn off the screen, for example, if it is known that the proximity distance is smaller than the preset threshold, it indicates that ears or cheeks of the human body are close to the screen of the terminal device, and thus, the terminal device is controlled to turn off the screen.
As another possible implementation manner, when the approaching object is a human body, an interactive special effect may also be provided in cooperation with a game application and the like, and different animations are displayed according to the approaching distance between the human body and the target sensing metal sheet in the terminal device, so as to indicate the approaching degree between the user and the terminal device, thereby forming an interesting display effect.
For example, as shown in fig. 5, the proximity of the user to the terminal device may be indicated by the size of a "ball" animation displayed on the screen, for example, as shown in fig. 5, as the distance between the user and the target sensing metal sheet approaches, the "ball" animation becomes larger and larger, and so on.
To sum up, the distance sensing processing method for a terminal device according to the embodiment of the present invention provides a terminal device, where the terminal device includes: the method comprises the steps that whether the capacitance value of each induction metal sheet changes or not is monitored, if the target induction metal sheet with the changed capacitance value is obtained, a medium and a distance close to the target induction metal sheet are determined according to the capacitance value change of the target induction metal sheet, and then the terminal equipment is subjected to corresponding operation processing according to the suspension position, the medium and the distance of the target induction metal sheet in the terminal equipment. Therefore, the proximity event of the terminal equipment is detected according to the suspended sensing metal sheet, the situation that a proximity sensor is arranged on the terminal equipment through a hole is avoided, and the screen occupation ratio of the terminal equipment is improved.
