Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A message sending method, a message sending apparatus, a touch device, a vehicle-mounted terminal, an electronic device, and a computer-readable storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a message transmission method according to an embodiment of the present invention. In an embodiment of the present invention, as shown in fig. 2, the sending of the message may be implemented by a touch panel, a microprocessor, a communication bus, an application processor. The touch control device can send the touch message corresponding to the touch control operation to the application processor through the communication bus, and the application processor is used for receiving and identifying the touch message to send out a corresponding instruction and control the running of related applications, so that the response to the touch control operation of the user is realized.
As shown in fig. 1, a message sending method according to an embodiment of the present invention includes the following steps:
s101, touch operation on the touch pad is detected, and first position information of the first touch operation detected currently is acquired.
It should be noted that, a user may perform a touch operation on the touch panel, detect the touch operation through the touch detection device, and acquire position information of the touch operation.
Optionally, the touch operation may include single-finger touch, multi-touch, gesture operation, and the like.
Optionally, the touch detection device may include a touch chip, a pressure sensor, and the like. For example, when a touch operation is detected by a touch chip, the touch chip may output a driving signal to a driving line of the touch panel, scan the driving line, receive a sensing signal from a corresponding sensing line, determine whether there is a touch operation by determining a value of the sensing signal, and generate an interrupt signal if there is a touch operation. The sensing signal may include a capacitance value, a resistance value, and the like.
Taking the sensing signal as an example of the capacitance value, when a user performs a touch operation on the touch panel, the capacitance value of the position of the touch operation on the touch panel changes, and the touch chip can detect the capacitance value on the touch panel, determine whether the touch operation exists according to the capacitance value, and acquire the position of the touch operation on the touch panel.
In an embodiment of the present invention, acquiring the position information of the touch operation may include establishing a coordinate system on the touch panel in advance, and using a coordinate corresponding to the touch operation as the position information of the touch operation. Taking the touch panel as a plane, a two-dimensional rectangular coordinate system may be established on the touch panel in advance, optionally, a two-dimensional rectangular coordinate system may be established with one corner of the touch panel as an origin, and a two-dimensional coordinate corresponding to the touch operation is used as the position information of the touch operation.
As shown in fig. 3, the touch panel is a rectangular planar touch panel, and a two-dimensional rectangular coordinate system may be established with the lower left corner of the touch panel as the origin, the lower frame of the touch panel as the X axis, and the left frame as the Y axis, so that the position information of the touch operation a may be obtained as coordinates (3, 3).
S102, second position information of a second touch operation of the last touch message is obtained.
And S103, identifying whether to send the touch message to the application processor according to the first position information and the second position information. Wherein the touch message carries first position information.
It should be noted that, each time it is determined to send a touch message to the application processor, the position information of the touch operation forming the touch message may be stored in a storage space of the touch detection device, for example, in a storage space of the touch chip.
For example, after acquiring the position information of the currently detected first touch operation, the touch detection device may call out, from its own storage space, second position information of a second touch operation that has formed a touch message last time, and identify whether to send the touch message to the application processor according to the first position information and the second position information.
In an embodiment of the present invention, identifying whether to send the touch message to the application processor according to the first location information and the second location information may include obtaining a distance between the first touch operation and the second touch operation, and identifying whether to send the touch message to the application processor according to a magnitude relationship between the distance and a preset distance threshold.
If the distance is greater than or equal to the preset distance threshold, it is indicated that the distance between the first touch operation and the second touch operation is relatively long, the difference between the first position information and the second position information is relatively large, because the touch message carries the position information, the touch message corresponding to the first touch operation and the touch message corresponding to the second touch operation are relatively large, in order to ensure the accuracy of the touch message, the touch message corresponding to the first touch operation needs to be sent to the application processor, and the touch message carries the first position information, so that the application processor can receive and identify the operation intention of the user according to the first position information, generate a corresponding control instruction, and control the operation of the related application. The preset distance threshold may be calibrated according to an actual situation, and may be preset in a storage space of the touch detection device, for example, may be preset in a storage space of the touch chip.
Optionally, a mapping relation or a mapping table between the position information of the touch operation and the instruction may be pre-established in a storage space of the application processor, and after the position information is obtained, the mapping relation or the mapping table is queried, so that a control instruction required under the current position information can be determined, and a corresponding control instruction is generated to control the operation of the relevant application.
If the distance is smaller than the preset distance threshold, it is indicated that the distance between the first touch operation and the second touch operation is short, the difference between the first position information and the second position information is not large, and because the touch message carries the position information, the difference between the touch message corresponding to the first touch operation and the touch message corresponding to the second touch operation is not large, in order to reduce the number of the touch messages sent to the application processor and reduce the load pressure of the communication bus, the touch message corresponding to the first touch operation may not be sent to the application processor at this time.
Therefore, according to the method, whether the touch message is sent to the application processor or not can be identified according to the size relation between the distance between the first touch operation and the second touch operation and the preset distance threshold, the accuracy of the touch message can be guaranteed, and meanwhile, the quantity of the touch message can be reduced, so that the load pressure of a communication bus is relieved.
For example, as shown in fig. 4, if the position information of the first touch operation is the coordinate a (5, 3), the position information of the second touch operation is the coordinate B (3,3), and the preset distance threshold is 1, the distance between the first touch operation and the second touch operation is 2 and is greater than the preset distance threshold, and in order to ensure the accuracy of the touch message, the touch message corresponding to the first touch operation may be sent to the application processor.
Or if the position information of the first touch operation is the coordinate C (3.5, 3), the position information of the second touch operation is still the coordinate B (3,3), and the preset distance threshold is 1, the distance between the first touch operation and the second touch operation is 0.5 and is smaller than the preset distance threshold, and in order to reduce the number of touch messages sent to the application processor and reduce the load pressure of the communication bus, the touch message corresponding to the first touch operation may not be sent to the application processor at this time.
Further, after sending the touch message to the application processor, in order to continue to detect whether there is a touch operation, the touch operation on the touch panel may be re-detected at an interval of a third preset time. The third preset time may be calibrated according to an actual situation, for example, may be calibrated to be 10 milliseconds, and the third preset time may be preset in the storage space of the touch detection device, for example, may be preset in the storage space of the touch chip.
Optionally, after sending the touch message to the application processor, in order to detect whether the touch operation disappears, the state of the touch panel may be detected, and when it is detected that the touch panel is in the release state, which indicates that the touch operation disappears, a prompt message released by the touch panel is sent to the application processor, so that the application processor can generate a corresponding control instruction according to the prompt message, and control the running of the related application.
Optionally, the state of the touch panel may be detected by a touch detection device. For example, when the state of the touch panel is detected by the touch chip, the touch chip may output a driving signal to a driving line of the touch panel, scan the driving line, receive a sensing signal from a corresponding sensing line, determine whether there is a touch operation and whether the touch operation disappears according to a value of the sensing signal and a change of the value, generate an interrupt signal if there is the touch operation, and stop generating the interrupt signal if the touch operation disappears, that is, the touch panel is in a release state.
In summary, according to the message sending method of the embodiment of the present invention, whether to send a touch message to an application processor can be identified according to the magnitude relationship between the distance between the currently detected first touch operation and the second touch operation that forms the touch message last time and the preset distance threshold, so that the accuracy of the touch message can be ensured, and the number of the touch messages sent to the application processor can be reduced to reduce the load pressure of a communication bus.
A message transmission method according to another embodiment of the present invention is described below with reference to fig. 5.
As shown in fig. 5, the message sending method according to the embodiment of the present invention includes the following steps:
s201, touch operation on the touch pad is detected, and first position information and time information of the first touch operation detected currently are acquired.
S202, second position information and time information of a second touch operation of the last touch message are acquired.
It should be noted that, time information corresponding to the touch operation may be acquired by installing a timer in the touch detection device, and optionally, after determining to send the touch message to the application processor, the time information of the touch operation forming the touch message may be stored in a storage space of the touch detection device, for example, in a storage space of a touch chip.
S203, acquiring the distance between the first touch operation and the second touch operation according to the first position information and the second position information.
And S204, identifying whether the distance is smaller than a preset distance threshold value.
If yes, step S205 is performed, and if no, step S207 is performed.
S205, a time interval between the first touch operation and the second touch operation is obtained. In an embodiment of the present invention, if it is recognized that the distance between the first touch operation and the second touch operation is smaller than the preset distance threshold, the time interval between the first touch operation and the second touch operation may be further obtained according to the time information of the first touch operation and the time information of the second touch operation that is called out from the storage space of the first touch operation and forms the touch message last time, and whether to send the touch message to the application processor is recognized according to a size relationship between the time interval and the first preset time. The first preset time may be calibrated according to an actual situation, and may be preset in a storage space of the touch detection device, for example, the first preset time may be preset in a storage space of the touch chip.
S206, whether the time interval is larger than or equal to a first preset time is identified.
If yes, step S207 is performed, and if no, step S209 is performed.
S207, sending the touch message to the application processor.
If the time interval is greater than or equal to the first preset time, it is indicated that the time interval between the first touch operation and the second touch operation is long, in order to avoid missing a touch message due to a recognition error, even if the touch message corresponding to the first touch operation is not much different from the touch message corresponding to the second touch operation, in order to ensure the accuracy of the touch message, the touch message corresponding to the first touch operation needs to be sent to the application processor, and the touch message carries the first position information, so that the application processor can receive and recognize the operation intention of the user according to the first position information, generate a corresponding control instruction, and control the operation of the related application.
And S208, storing the first position information and the time information of the first touch operation as the second position information and the time information of the second touch operation, and returning to execute the detection and subsequent steps of the touch operation on the touch panel.
In an embodiment of the present invention, after sending the touch message to the application processor, the touch detection device may further delete the second position information and the time information of the second touch operation from the storage space, and use the first position information and the time information of the first touch operation as the second position information and the time information of the second touch operation, and store the second position information and the time information in its own storage space, so that the storage space stores the position information and the time information of at most one touch operation at the same time, which is beneficial to saving the storage space of the touch detection device.
And S209, not sending a touch message to the application processor, and returning to execute the detection of the touch operation on the touch pad and the subsequent steps.
If the time interval is less than the first preset time, which indicates that the time interval between the first touch operation and the second touch operation is short, repeated operations may occur to the user, and at this time, the touch message corresponding to the first touch operation should be slightly different from the touch message corresponding to the second touch operation.
Therefore, after the method identifies that the distance between the first touch operation and the second touch operation is smaller than the preset distance threshold, whether a touch message is sent to the application processor or not can be identified according to the size relation between the time interval of the first touch operation and the second touch operation and the first preset time, the accuracy of the touch message can be ensured, and meanwhile, the number of the touch messages sent to the application processor can be reduced, so that the load pressure of a communication bus is reduced.
For example, after recognizing that the distance between the first touch operation and the second touch operation is smaller than the preset distance threshold, if the time corresponding to the first touch operation is 3 seconds, the time corresponding to the second touch operation is 1 second, and the first preset time is 1 second, the time interval between the first touch operation and the second touch operation is 2 seconds and is greater than the first preset time, and in order to ensure the accuracy of the touch message, the touch message corresponding to the first touch operation may be sent to the application processor at this time.
Or if the time corresponding to the first touch operation is 1.2 seconds, the time corresponding to the second touch operation is still 1 second, and the first preset time is 1 second, the time interval between the first touch operation and the second touch operation is 0.2 seconds and is less than the first preset time, in order to reduce the number of touch messages sent to the application processor and reduce the load pressure of the communication bus, the touch message corresponding to the first touch operation may not be sent to the application processor at this time.
In summary, according to the message sending method in the embodiment of the present invention, after it is identified that the distance between the first touch operation and the second touch operation is smaller than the preset distance threshold, whether to send the touch message to the application processor can be identified according to the magnitude relationship between the time interval between the first touch operation and the second touch operation and the first preset time, so that the accuracy of the touch message can be ensured, and the number of the touch messages sent to the application processor can be reduced, so as to reduce the load pressure of the communication bus.
As another possible implementation manner, the touch operation on the touch panel is detected, after the first position information of the currently detected first touch operation is acquired, whether the first touch operation is the first operation within the second preset time may be identified, if so, it indicates that the time interval between the first touch operation and the second touch operation forming the touch message last time is longer, and in order to ensure the accuracy of the touch message, the distance between the first touch operation and the second touch operation may not be determined at this time, and the touch message is directly sent to the application processor, so that the message sending efficiency is improved. The second preset time may be calibrated according to an actual situation, and may be preset in a storage space of the touch detection device, for example, the second preset time may be preset in a storage space of the touch chip.
If not, it is indicated that the time interval between the first touch operation and the second touch operation is short, and in order to reduce the number of touch messages sent to the application processor and reduce the load pressure of the communication bus, it is necessary to continue to acquire the second position information of the second touch operation which formed the touch message last time and subsequent steps thereof.
To make the present invention more clear to those skilled in the art, fig. 6 is a flowchart of a message sending method according to a specific example of the present invention, and as shown in fig. 6, the message sending method may include the following steps:
s301, detecting the touch operation on the touch pad, and acquiring first position information of the currently detected first touch operation.
S302, whether the first touch operation is the first operation within a second preset time is identified. If yes, step S303 is performed, and if no, step S306 is performed.
S303, sending the touch message to the application processor.
S304, saving the first position information and the time information of the first touch operation as the second position information and the time information of the second touch operation.
And S305, delaying for a third preset time, and returning to continue to execute the detection and subsequent steps of the touch operation on the touch panel.
S306, second position information of a second touch operation of the last touch message is obtained.
S307, acquiring the distance between the first touch operation and the second touch operation according to the first position information and the second position information.
S308, whether the distance is smaller than a preset distance threshold value or not is identified. If yes, step S309 is performed, and if no, step S303 is performed.
S309, acquiring a time interval between the first touch operation and the second touch operation.
And S310, identifying whether the time interval is greater than or equal to a first preset time, if so, executing the step S303, and if not, returning to continuously execute the steps of detecting the touch operation on the touch pad and the subsequent steps.
