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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, a first embodiment of the present invention provides a method for processing touch data, which can be executed on a TV set, and includes the following steps:
and S10, receiving the data generated by the touch frame connected currently.
In this embodiment, the touch frame may be an Infrared touch frame, the Infrared touch frame (Infrared TouchScreen Technology) is formed by Infrared emitting and receiving sensing elements mounted on a touch screen frame, an Infrared detection net is formed on the screen surface, and any touch object can block the Infrared on the touch points to realize the touch screen operation. The infrared touch frame product can be mounted on electronic devices such as a personal computer, a television, a tablet personal computer and the like, for example, the external infrared touch frame is fixed in front of a display of the TV complete machine and can be connected with the TV complete machine through a USB communication interface. In the embodiment, the complete TV set can be understood as a large flat TV, and an Android board card is configured on the TV set, and the TV set basically has the same functions as a PC (computer), such as USB communication, UART communication, HDMI communication, VGA communication, and the like. It can be understood that the method can also be executed on an electronic device such as a personal computer, a tablet computer, a notebook computer, and the like, so as to implement processing of the touch data.
In this embodiment, the algorithm module has been stripped from the touch frame bottom software, and is run in a system of a TV complete machine in a driving manner, as shown in fig. 2 as an example, the driving module mainly consists of three parts, which are a driving communication module, a driving data processing module (protocol module), and a driving algorithm module, wherein in the driving communication module, its main function is to communicate with a USB interface of a device, and can communicate with the USB interface of the touch frame through an interface packaged in a libusb library under Windows and Linux, while in the Android system, since its kernel is Linux, the bottom USB interface (USB _ fill _ bulk _ ub, USB _ submit _ urb, etc.) reserved by Linux kernel can also be used to communicate with the device.
In this embodiment, as an example, after the touch frame is powered on, the touch frame will perform a scanning operation. When the touch frame is detected to be successfully connected with the complete TV set, the driving communication module sends a notification instruction to the touch frame to enable the touch frame to start sending touch data, and it should be noted that the driving communication module enables the touch frame to send the touch data through the instruction, so that other communication abnormalities caused by the fact that the touch frame sends the touch data all the time can be avoided, for example, some matched application programs or software are used. Here, the touch frame is scanned once at intervals, and the scanned data is stored in the USB buffer, but the data may also be stored in another predetermined buffer, and it should be noted that not only the touch data but also other data, such as command data, are stored in the buffer. Here, if the buffer is full in the buffer, the old touch data is overwritten by the new touch data. In this embodiment, the driving communication module is in a state of always reading the data in the buffer after sending the notification command, so that the data generated by scanning from the touch frame can be received.
And S20, if the data is detected to be touch data, reading a frame of light state data from the touch data.
In this embodiment, after the drive communication module reads the data, all the read data are transmitted to the drive data processing module, and the drive data processing module performs related operations. As an example, if the driving data processing module detects that the data is touch data, one frame of light state data is read from the touch data each time, where the one frame of light state data is different according to a different data format and contains different data amounts.
In this embodiment, the touch frames with different sizes have different numbers of light rays included in the optical net, and the number of light rays included in the touch frames is also different according to the requirement of the touch frames on precision. The larger the size, the more the lamp tubes are, the more light rays are, the higher the precision, the more light rays are contained, and the light density of the optical net is higher. The more the light is, the more the data representing the three values a, b and c are, and in order to more effectively transmit the large amount of data to the driving end, the scanned touch data sometimes needs to be compressed and then transmitted. However, it is necessary to distinguish between the compressed data and the uncompressed data when transmitting, otherwise, it cannot be determined whether the data is compressed or uncompressed data, so the format of the compressed touch data may be defined as data beginning with 0x0a, the format of the uncompressed touch data may be defined as data beginning with 0x0b, and the format of the other command data may be defined as command data beginning with 0 xab. In this embodiment, the USB transfer transfers 64 bytes at a time, as shown in FIG. 3, where FIG. 3 shows two types of transfer data. In this embodiment, the amount of data included in the light status data represents the data size that can be used for calculating the seek point at a time, i.e., the data of one frame. For example, if one frame of light status data in the uncompressed touch data is fixed to be data with a size of 3kb, and the intensity of light in the compressed touch data is different according to the touch position, the one frame of light status data in the compressed touch data is different from 1kb to 4 kb. In this embodiment, the driving data processing module may determine whether the data is the touch data according to a format of the data.
S30, processing the read light state data according to the initialized algorithm to generate original coordinate data; wherein the initialized algorithm is generated from an original algorithm and initialization parameters from the touch frame.
And S40, triggering a touch event according to the original coordinate data.
In this embodiment, before receiving touch data, a system memory is applied on the complete TV set and an initialized algorithm is generated according to an original algorithm and initialization parameters from the touch frame. After the driving data processing module reads a frame of light state data, the light state data is transmitted to the initialized algorithm to be operated and calculated to generate original coordinate data, and a touch event is triggered according to the original coordinate data. In this embodiment, the processing the read light state data according to the initialized algorithm to generate original coordinate data specifically includes: and transmitting the light ray state data to the initialized algorithm to obtain original coordinate data corresponding to the light ray state data. In this embodiment, as an example, if the light state data is read by the driving data processing module, the light state data is input into the initialized algorithm to perform point finding, stain removing, point matching, gesture processing, and the like, so as to generate original coordinate data related to the light state data.
In an implementation manner of this embodiment, as shown in fig. 2, coordinate mapping may be performed on the calculated coordinate data in the driving, and the mapped coordinates are reported to the TV system in response to the event reported by the driving. Specifically, coordinate mapping is carried out on the original coordinate data to generate target coordinate data; transmitting the target coordinate data to an input subsystem; and reporting the target coordinate data to a main system through the input subsystem so as to trigger a touch event. In this embodiment, since the generated original coordinate data may have a difference with respect to a position on a display of the complete TV, coordinate mapping (calibration) needs to be performed on the original coordinate data to generate target coordinate data, and the target coordinate data is returned to the driving communication module by the driving data processing module in the final sending processing, and then the driving communication module transmits the target coordinate data to the host system, and the host system triggers a touch event according to the target coordinate data. In this embodiment, the touch event may be reported by calling an Input subsystem (i.e., an Input subsystem), for example, after the drive communication processing module receives the target coordinate data, the target coordinate data is uploaded to the Input subsystem, the Input subsystem directly uploads the target coordinate data to the host system, and the host system triggers the touch event according to the target coordinate data.
In this embodiment, for sending the target coordinate data to the host system, in addition to directly reporting through the Input subsystem, the target coordinate data may also be returned to the touch frame, and the touch frame sends the touch event through an hid (human interface device) interface.
In another implementation manner of this embodiment, the original coordinate data obtained through the algorithm without coordinate mapping may be sent to the touch frame for coordinate mapping, and the TV system may respond to the touch event reported by the touch frame. Specifically, the drive data processing module transmits the read touch data to the initialized algorithm for operation and calculation, original coordinate data (namely target coordinate data) which are not subjected to coordinate mapping are obtained through algorithm calculation, the original coordinate data are subjected to coordinate mapping through the touch frame, and the mapped data are reported to the TV system to trigger a touch event. In this embodiment, the triggering a touch event according to the target coordinate data specifically includes: returning the original coordinate data to the touch frame, wherein the original coordinate data is used for triggering the original coordinate data to be subjected to coordinate mapping on the touch frame; and receiving first data subjected to coordinate mapping processing of the touch frame, and triggering a touch event according to the first data. In this embodiment, the driving communication module needs to transmit the original coordinate data which is not subjected to coordinate mapping and calculated according to the algorithm to the touch frame, for example, the driving communication module transmits the original coordinate data which is not subjected to coordinate mapping back to the data processing module in the touch frame through the USB interface, and the data processing module in the touch frame may transmit the original coordinate data to the data transmission processing function according to the packet header of the original coordinate data, perform related coordinate mapping on the original coordinate data, obtain the first data after coordinate mapping processing by the touch frame, and upload the first data to the TV system after repackaging processing, so as to trigger a touch event on the TV system according to the first data. It should be noted that, in addition to the instruction data, other data that cannot be used for calculating the coordinates may be regarded as interference data, and the interference data may be discarded.
In this embodiment, the method further includes: and if the data is detected to be instruction data, responding the instruction data to a function processing function, and generating an instruction result to perform related setting according to the instruction result.
In this embodiment, not only touch data but also instruction data is stored in the USB buffer, where the instruction data may be setting instruction data in a received transmission format, or external calibration instruction data, or the like. When the driving data processing module detects that the data sent by the driving communication module is instruction data, the instruction data are sent to the function processing function to respond, after an instruction result is obtained through the response, the driving can perform corresponding setting according to the instruction result, for example, a calibration instruction, and when the driving receives the calibration instruction, the driving can perform corresponding setting, including whether coordinate data are returned to the touch frame or not, and the setting is that only single-point touch is responded. Here, the drive data processing module processes one packet of instruction data every time it reads one packet of instruction data.
In this embodiment, in order to synchronize data as much as possible, a mutual exclusion lock, a kernel lightweight semaphore complete, and other synchronization mechanisms may be used in the driver, so that data can be transmitted as much as possible in time, and data synchronization is achieved.
To facilitate an understanding of embodiments of the present invention, several practical examples will be described below.
The first embodiment is as follows: and moving the algorithm drive into an android whole machine system for operation, and performing scheduling operation by using system resources. The touch frame infrared LED lamp scans data, the obtained original data (namely touch data) are transmitted to an algorithm driver in the android whole machine system through a USB interface, calculation is carried out through the driver, an Input subsystem is called, and the coordinate data obtained through calculation are directly uploaded to the android whole machine system.
Example two: the algorithm is stripped from the touch frame software and independently developed into a drive to be operated on the whole machine system. The scanning data of the touch frame infrared LED lamp is transmitted through the USB interface and transmitted to the algorithm driver in the whole machine system, the coordinate data is obtained through algorithm calculation, the coordinate data is thrown to another driver through a system interface function, the other driver can be developed and maintained by a client, and the touch event is reported and triggered by the driver developed by the client, so that the client driver can realize the functions of touch penetration, touch extension and the like on the touch data driven by the algorithm.
In summary, the present embodiment provides a method for processing touch data, in which an algorithm is stripped from a touch frame software, and is separately developed to be a driver to run on a complete machine system, and by using the advantages of hardware resources of an electronic device connected to the touch frame, complex algorithm operations and processing of a large data volume can be completed, so that the utilization rate of the hardware resources in the overall touch scheme is improved; according to the initialized algorithm, touch data from the touch frame are processed to trigger a touch event, so that the problem that the MCU of the touch frame occupies too many resources by the algorithm to reduce the overall performance of the MCU can be solved, and the problem that the existing touch frame hardware cannot improve the multitask parallel processing capability of software can be solved; and under the premise of not changing the hardware of the touch frame, the expansibility and the portability of software can be improved.
Second embodiment of the invention:
referring to fig. 4, on the basis of the first embodiment, before S10, the method further includes:
s101, acquiring equipment information of a connected touch frame;
s102, identifying the touch frame according to the equipment information;
in this embodiment, the algorithm module needs to be stripped from the underlying software of the touch frame and run in a driving manner in the system of the TV set, so that before processing touch data, the related algorithm in the TV set needs to be initialized. As an example, the touch frame may be connected to a TV set via a USB interface (i.e., a communication interface), and when the touch frame is powered on, the touch frame uploads device information to a system layer of the TV set, where the device information may be generated according to a vendor number (VID) and a product identification code (PID), and represents a unique identifier of the touch frame, and when the touch frame successfully uploads the device information, the touch frame is in a state of monitoring a command. Therefore, the driving communication module can acquire the equipment information of the touch frame connected with the whole TV and identify the touch frame according to the equipment information.
S103, receiving initialization parameters from the touch frame; wherein the initialization parameters include a total number of rays of the optical network, a parameter value representing one ray, and a data type;
and S104, initializing the original algorithm according to the initialization parameters to generate an initialized algorithm.
In this embodiment, after the driving communication module identifies the touch frame, that is, after the touch frame and the TV complete machine successfully establish a communication connection, the driving communication module sends a command or instruction of "reading the algorithm initialization parameter" to the touch frame through the USB interface, and when the touch frame receives the command of reading the algorithm initialization parameter, the driving communication module starts to upload the initialization parameter. And then, after the drive communication module receives the initialization parameter, applying for an internal memory to a main system of the complete TV set, and initializing the original algorithm according to the initialization parameter.
In the present embodiment, the initialization parameter includes, as examples, the total number of rays of the optical network, three values (a, b, c) representing one ray, a data type, and the like. It should be noted that the basic principle of realizing touch by the infrared touch frame is that the transmitting lamp transmits a signal, the receiving lamp receives the signal transmitted by the transmitting lamp, and once the receiving lamp does not receive the signal, it is considered that shielding exists between transmitting and receiving at this time, and one transmitting and one receiving are actually equivalent to connecting a line between the transmitting lamp and the receiving lamp. The whole touch frame has many transmitting lamps and receiving lamps, many lines can be abstracted according to the arrangement and combination mode, all the lines are combined into a touch frame optical network diagram, as shown in fig. 5, fig. 5 shows a simple optical network diagram, and the arrow points to the receiving lamp. Mathematically, a ray can be represented by the equation a x + b y + c 0, so that three values a, b, and c can be determined to plot a ray. Storing these three values is storing an optical network.
In this embodiment, the initializing an original algorithm according to the initialization parameter to generate an initialized algorithm specifically includes:
identifying the initialization parameters to obtain algorithm initialization data;
and transmitting the algorithm initialization data to an original algorithm for initialization processing to generate an initialized algorithm.
In this embodiment, after the driving communication module obtains the initialization parameters, the initialization parameters are transmitted to the driving data processing module, the driving data processing module identifies the initialization parameters, and after the initialization parameters are successfully identified as algorithm initialization data, the algorithm initialization data are transmitted to an original algorithm, a memory is applied to a system, the original algorithm is initialized, and an initialized algorithm is obtained. And after the algorithm is initialized successfully, the driving communication module sends a notification command or an instruction to the touch frame to enable the touch frame to send touch data.
By the method, the algorithm module is stripped from the bottom layer software of the touch frame, so that the problem that the overall performance of the MCU is reduced due to the fact that the MCU of the touch frame is occupied by too many resources by the algorithm can be solved; and receiving initialization parameters from the touch frame and initializing the algorithm, and changing the algorithm scheme at any time by using the advantages of the hardware resources of the whole TV set, so that the method can be adapted to different algorithm mechanisms.
