Description
Technical Field
The application relates to the technical field of key control, in particular to a key touch method and device, touch equipment and a readable storage medium.
Background
The key interaction is one of the commonly used man-machine interaction modes, and a user can select and set the functions of the equipment through keys, wherein the keys comprise mechanical keys, touch keys and the like. The touch key includes a capacitive touch manner.
For the product with the metal key cover plate, the metal cover plate has a shielding effect, so that when the capacitive touch key is attached to the front cover plate, the touch signal is shielded, and the capacitive touch key is not effective. If the capacitive touch is required to be touched, the metal cover plate needs to be hollowed out, so that the capacitive touch keys are completely exposed, and the whole appearance of the product is affected by the large-area hollowing.
In addition, since capacitive touch detects touch by detecting a change in current, when a user's hand is dry, a phenomenon of touch invalidation occurs.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 and fig. 2 in combination, an internal structure and an external structure of a touch device 10 provided in the embodiments of the present application are schematically illustrated, where the touch device 10 includes a device body 11, a metal cover 12, a touch key 13, and a control system 14 (of the touch key).
The metal cover 12 has an opening 120 (shown by a dotted line), the touch key 13 is disposed below the opening, and the touch key 13 includes a light wave receiving unit 130 and a light wave emitting unit 132.
As an alternative embodiment, the size of the opening 120 matches the overall size of the touch key 13. Correspondingly, the position of the light wave receiving unit 130 is a position capable of receiving the light wave incident from the opening 120; the position of the light wave emitting unit 132 is a position where light waves can be emitted from the opening 120.
The position of the opening 120 on the metal cover 12 may be a position of a mark (such as a mark at a dashed line position in fig. 1) provided on the metal cover 12 for indicating the touch key 13. Such as: assuming that the touch key 13 functions as a device switch, a pattern (or other implementable marks) representing the device switch may be provided on the metal cover 12, and then the opening 120 is provided at the pattern, so that the design of the opening 120 is integrated with the design of the whole metal cover 12, and the appearance of the touch device 10 is not affected.
In addition, the number of the touch keys 13 may be one or more. If the number of the touch keys 13 is one, the openings 120 are correspondingly arranged one. If the number of the touch keys 13 is plural, the openings 120 are correspondingly plural, and one opening 120 corresponds to one touch key 13, for example: assuming that the touch device 10 includes two volume control keys (volume up key and volume down key), the volume up key corresponds to the first opening, the volume down key corresponds to the second opening, and the first opening and the second opening are disposed at different positions on the metal cover 12, such as: the first opening is arranged at the identification pattern with the volume increased, and the second opening is arranged at the identification pattern with the volume decreased.
As an alternative embodiment, the lightwave receiving unit 130 and the lightwave transmitting unit 132 can be independent components, such as: a transmitting tube and a receiving tube. Or may be two parts that form a single element, such as a single element that includes both the emitter tube and the receiver tube.
As an alternative embodiment, the control system 14 includes a host or a motherboard, a main control chip, a signal processing circuit, and a peripheral circuit. The host or the motherboard can be understood as an operating system of the touch device 10, and is configured to implement a function corresponding to the touch key according to the touch operation detected by the main control chip. The main control chip is used for realizing the detection of the touch operation, and the signal processing circuit and the peripheral circuit are circuits required by the main control chip for realizing the detection of the touch operation. The roles of the various modules in the control system 14 are described in connection with the method in the following embodiments.
The operating system may be a Windows or android system, and has an interface (including a hardware interface and a software interface) for receiving the touch operation detection information, and can perform corresponding operations or reactions in combination with the current state and the touch operation detection information.
The main control chip may be an MCU (micro controller Unit) (e.g., STM32F103 series chip). It may include: memory, processor, peripheral interface and serial port. The various elements are electrically connected, directly or indirectly, to enable transmission or interaction of data. For example, electrical connections between these components may be made through one or more communication or signal buses.

Based on the above description of the hardware structure, referring to fig. 3, a flowchart of a key touch method applied to the control system 14 according to an embodiment of the present application is provided, where the method includes:
step 201: the light wave emission unit 132 is controlled to emit light waves.
Step 202: when the light waves received by the light wave receiving unit 130 are acquired, it is determined whether a touch operation of the touch key 13 is currently performed.
Step 203: when it is determined that the touch operation of the touch key 13 is currently performed, the operation corresponding to the function of the touch key 13 is executed.
Compared with the prior art, the touch key 13 is arranged below the opening formed in the metal cover plate 12, and the appearance of the metal cover plate 12 is not affected. The touch key 13 includes a light wave receiving unit 130 and a light wave transmitting unit 132, and the light wave receiving unit 130 and the light wave transmitting unit 132 control the light wave transmitting unit 132 to transmit light waves first, when the light waves received by the light wave receiving unit 130 are obtained, the light waves represent that the transmitted light waves are reflected due to a shielding effect caused by a touch operation of a user, and at this time, whether the touch operation is performed currently can be determined. Compared with capacitive touch, the scheme provided by the application avoids the problem of touch failure caused by the fact that the fingers of the user are dry, and therefore the effectiveness of touch operation of the user is improved.
The embodiments of steps 201-203 are described next in connection with an embodiment of control system 14.
As an alternative implementation manner of step 201, after the touch device 10 is powered on, the main control chip generates a pulse signal corresponding to the touch key 13, and then the signal processing circuit converts the pulse signal into a light wave, and then the light wave is emitted by the light wave emitting unit 132. That is, the main control chip is used for generating the pulse signal, the signal processing circuit is used for converting the pulse signal, and the lightwave emitting unit 132 is used for emitting lightwaves.
If the touch device 10 only includes one touch key 13, the main control chip may generate a pulse signal of the one touch key 13 according to a preset code corresponding to the touch key 13, and send the pulse signal to the signal processing circuit, and the signal processing circuit converts the pulse signal and sends out a light wave by the light wave emitting unit 132. The main control chip can circularly generate the pulse signal according to a preset period, wherein the preset period is a time period below millisecond.
In this embodiment, the preset code may be a code for representing the function of the one touch key 13, the preset code may be a code for representing the name of the one touch key 13, or the preset code may be another executable code. The preset coding forms include but are not limited to: numbers, letters, combinations of numbers and letters, and the like.
Assuming that the touch device 10 includes a plurality of touch keys 13, step 201 may include: the main control chip generates first pulse signals corresponding to the touch keys 13 according to preset codes respectively, and the preset codes corresponding to different touch keys 13 are different; the signal processing circuit converts the first pulse signal into a light wave, and the light wave is emitted by the light wave emitting unit 132 of each touch key 13. The main control chip can cyclically generate a plurality of first pulse signals according to a preset period, and the preset period is also a time period below millisecond level.
In this embodiment, the preset code may be a code for representing functions of different touch keys 13, a code for representing names of different touch keys 13, or other implementable codes. The preset coding forms include but are not limited to: numbers, letters, combinations of numbers and letters, and the like. Such as: the codes of the plus key and the minus key of the volume control key are respectively as follows: v0001 and v 00002.
Further, when the main control chip generates the pulse signal, a corresponding binary pulse wave may be generated according to the code, the binary pulse wave is the generated pulse signal, and the binary pulse wave may be 8 bits.
After the binary pulse wave is acquired by the signal processing circuit, the binary pulse wave is converted into a light wave, which can be understood as invisible light with smaller power, and when the invisible light encounters an obstacle, the light wave is reflected, that is, when a finger of a user touches the opening 120 corresponding to the touch key 13, the light wave emitted by the light wave emitting unit 132 is reflected.
When the number of the touch keys 13 is large, in order to ensure the light wave emitting efficiency of the light wave emitting unit 132 of each touch key 13, a plurality of signal processing circuits may be provided, and then the light wave emitting unit 132 is reasonably divided, for example: assuming that there are 10 touch keys 13, the light wave emission of 5 touch keys 13 is controlled by the first signal processing circuit, and the light wave emission of the other 5 touch keys 13 is controlled by the second signal processing circuit.
In addition, the embodiment in which the signal processing circuit converts the pulse wave into the light wave belongs to the technology known to those skilled in the art, and is not described in the embodiment of the present application.
Further, after each light wave emitting unit 132 emits a light wave, if the user has a touch operation of the touch key 13, each light wave receiving unit 130 correspondingly receives the reflected light wave, but because each light wave receiving unit 130 has an interference event, for example: since the light waves are received by the light wave receiving unit 130 due to an incorrect operation, light waves transmitted by other devices, and the like, step 202 is executed after step 201, and when the light waves received by the light wave receiving unit 130 are acquired, it is determined whether there is a touch operation of the touch button 13 currently.
As an optional implementation manner, for the case of multiple touch keys 13, step 202 includes: when light waves received by the light wave receiving unit of any touch key 13 are acquired, the received light waves are converted into second pulse signals; and judging whether the touch operation of the corresponding touch key 13 exists at present according to the first pulse signal and/or the second pulse signal corresponding to any touch key 13.
For the case of one touch key 13, step 202 includes: when light waves received by the light wave receiving unit of the touch key 13 are acquired, the received light waves are converted into second pulse signals; and judging whether the touch operation of the touch key 13 exists currently according to the first pulse signal and/or the second pulse signal corresponding to the touch key 13.
It can be seen that the control system 14 processes the light waves received by each touch key 13 in the same way regardless of the touch key 13 or the touch keys 13.
In the control system 14, the signal processing circuit converts the light wave received by the light wave receiving unit 130 into a second pulse signal, and then sends the second pulse signal to the main control chip, and the main control chip determines whether the touch operation of the touch key 13 is currently performed according to the first pulse signal and/or the second pulse signal.
When the main control chip determines the touch operation, there are three embodiments, which are described below.
In the first embodiment, it is determined whether a time interval between the emission time of the light wave converted by the first pulse signal corresponding to any touch key 13 and the receiving time of the received light wave is within a preset time range; if the time interval between the emission time of the light wave converted by the first pulse signal corresponding to any touch key 13 and the receiving time of the received light wave is within the preset time range, it is determined that the touch operation of the corresponding touch key is currently performed.
In the first embodiment, the preset time range may be determined according to the speed of light propagation and the maximum distance and the minimum distance between the finger and the touch key 13 when performing the touch operation. It will be appreciated that the interference events excluded in this embodiment are: the interference time due to the non-touch operation of the finger, such as: the finger is currently just stroked over the touch key 13, but no touch is made.
For example, if the speed of light propagation is c, when the finger performs the touch operation, the maximum distance between the finger and the touch key 13 is d1, and the minimum distance between the finger and the touch key 13 is d2, the upper time limit is d1/c, and the lower time limit is d 2/c. The maximum distance and the minimum distance between the finger and the touch key 13 during the touch operation depend on the first relative distance between the metal cover 12 and the touch key 13 and the second relative distance between the finger and the metal cover 12 during the touch operation. The first relative distance is a fixed value, the second relative distance can determine a maximum value and a minimum value according to the actual operation condition, and the maximum distance is the fixed value plus the maximum value; the minimum distance is a fixed value plus a minimum value.
For the time interval, when the main control chip sends out the first pulse signal, it can start timing, assumed as T0, and then when the second pulse signal is received, assumed as T1, the time interval is: T1-T0. It should be noted that the time for the signal processing circuit to convert the signal is almost negligible, and thus, the time for sending out the first pulse signal may represent the transmission time, and the time for receiving the second pulse signal may represent the reception time.
Of course, if the performance of the signal processing circuit is poor, a processing time may be added to the time of sending the first pulse signal and the time of receiving the second pulse signal, and the two times after the addition of the processing time may be used as the sending time and the receiving time.
In the first embodiment, the preset time range may be replaced, for example: the preset condition is not a time range but a distance range, after the time interval is obtained, a distance value corresponding to the time interval is determined based on the time interval and the speed of light propagation, then whether the distance value is within the distance range is judged, if yes, touch operation is determined, and if not, non-touch operation is determined.
In the embodiment of the application, when the touch operation is judged according to the first pulse signal corresponding to the transmitting light wave and the second pulse signal corresponding to the receiving light wave, the interference event is eliminated through the judgment of the time interval, and the accuracy of the touch operation judgment is improved.
In the second embodiment, the second pulse signal is analyzed to obtain a code corresponding to the second pulse signal; judging whether the code corresponding to the second pulse signal is consistent with the code preset by any touch key 13; if the code corresponding to the second pulse signal is consistent with the code preset by any touch key 13, it is determined that the touch operation of the corresponding touch key 13 is currently performed.
In a second embodiment, if the code of the second pulse signal is not consistent with the preset code, the light wave may be light wave emitted by other devices, such as infrared light emitted by a remote controller and a laser pen, and not light wave reflected by the user when performing a touch operation.
When the second pulse signal is analyzed, the principle is similar to that when the first pulse signal is generated according to the preset code, and when the first pulse signal is generated, the preset code is converted into the pulse signal according to the format of the pulse signal (the 8-bit binary pulse in the foregoing embodiment is exemplified), and correspondingly, when the second pulse signal is analyzed, the pulse signal is restored into the code according to the format of the pulse signal.
Because the received light wave and the emitted light wave are processed in the same way, if the converted code is different from the preset code, the received light wave and the emitted light wave are not the same, and can be judged as an interference event.
In the third embodiment, it is determined whether a time interval between the emission time of the light wave converted by the first pulse signal corresponding to any touch key 13 and the receiving time of the received light wave is within a preset time range; if the time interval between the emission time of the light wave converted by the first pulse signal corresponding to any touch key 13 and the receiving time of the received light wave is within a preset time range, analyzing the second pulse signal to obtain a code corresponding to the second pulse signal; judging whether the code corresponding to the second pulse signal is consistent with the code preset by any touch key 13; if the code corresponding to the second pulse signal is consistent with the preset code, it is determined that the touch operation of the corresponding touch key 13 is currently performed.
In a third embodiment, the first embodiment is combined with the second embodiment, the first embodiment is used to determine the first interference event, if the first interference event does not belong to the first interference event, the second embodiment is used to determine the second interference event, and if the second interference event does not belong to the second interference event, the final determination result is that the interference event is not the first interference event, and the current touch operation of the touch key 13 is determined. Of course, in the determination process, if the first interference event belongs to, the interference event is directly determined, and it is determined that there is no touch operation of the touch key 13 currently. If the second type of interference event belongs to, the interference event is directly determined, and it is determined that there is no touch operation of the touch key 13 currently.
The detailed embodiments of the first embodiment and the second embodiment are the same as those described in the previous embodiment, and the description is not repeated here.
In the third embodiment, the determination orders of the first interference event and the second interference event may be exchanged, that is, the second interference event may be determined first, and then the first interference event may be determined, which is not limited in the embodiment of the present application.
For the three embodiments, in practical application, different application scenarios of the touch device 10 and the setting condition of the touch key 13 can be reasonably selected. If there are more touch keys 13 arranged on the touch device 10 and there are more other light waves in the application scene, at this time, there is a probability that both of the two kinds of interference events occur, and the third embodiment can be adopted. The first embodiment may be adopted if the touch device 10 has fewer touch keys 13 and there is substantially no other light wave in the application scene. If the touch device 10 has fewer touch keys 13 and there are more light waves in the application scene, the second embodiment may be adopted.
After the touch operation is determined in step 202, there are two results, the first result is: determining that there is no touch operation of the touch key 13, at this time, continuing to perform step 201, or continuing to perform step 202 without performing the subsequent step 203. The second result is: it is determined that the touch operation of the touch key 13 is currently performed, and step 203 is executed to execute the function of the touch key 13.
In step 203, the main control chip sends the determination result of the touch operation to the host or the motherboard, and the host or the motherboard executes a corresponding operation. Such as: the judgment result of the main control chip is as follows: if the current operation is a volume up touch operation, the host or the motherboard will execute the volume up operation on the touch device 10.
As an optional implementation manner, when the number of the touch keys 13 is multiple, step 203 includes: when it is determined that there are currently touch operations of the plurality of touch keys 13, corresponding operations are executed according to a preset function corresponding to simultaneous touch operations of the plurality of touch keys 13.
In this embodiment, the touch device 10 supports simultaneous touch of a plurality of touch keys 13, and is also configured with corresponding functions. Such as: when the volume plus key and the on-off key are simultaneously touched, the corresponding function is screen capture. Therefore, for the operating system, the touch device 10 may be controlled to perform a corresponding operation or reaction according to a preset corresponding function and currently received touch operation information.
In the embodiment of the present application, when the plurality of touch keys 13 are touched simultaneously, corresponding functions are provided, so that flexibility and convenience in operation of the touch keys 13 are achieved.
