Description
Technical Field

Background
The input device can input control instructions to the main control device, and an application program in the main control device recognizes the control instructions and responds. Because the input devices are various, such as a mouse, a keyboard, a touch screen, etc., and the input modes are different, if a corresponding driver is configured for each different input device in the main control device, so that the application program in the main control device can recognize the control instructions input by the different input devices, the development, operation and maintenance costs are too high.
In order to simplify the driving in the main control device in the related art, an input subsystem (input subsystem) is often provided in an operating system (such as a linxu operating system and an Android operating system) of the main control device. An event driver and a device driver are provided in the input subsystem, and the input subsystem interfaces with the application program through the event driver and interfaces with the input device through the device driver. The input subsystem can convert the control instruction input by the input equipment into a standard event meeting a preset standard, and inputs the standard event into the application program, so that the application program executes corresponding business operation, and therefore the application program can recognize the control instruction input by different input equipment only by being in butt joint with the event driver.
However, in the related art, the device driver of the input subsystem can only interface with a USB (Universal Serial Bus) driver, and therefore, in the related art, only the input device accessing the master device through the USB interface can access the input subsystem. For the input devices that access the main control device through the serial port, since the input subsystem cannot be accessed, the control instructions input by the input devices cannot be converted into standard events through the input subsystem, and therefore, corresponding drivers need to be configured for the application programs for the input devices, which increases the development and operation and maintenance costs of the application programs.

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.
In order to more clearly describe the standard event construction method provided by the embodiment of the present invention, an application scenario of the standard event construction method provided by the embodiment of the present invention will be exemplarily described below, it should be understood that the application scenario illustrated below is only one possible application scenario of the standard event construction method provided by the embodiment of the present invention, and the standard event construction method provided by the embodiment of the present invention may also be applied to other possible application scenarios in other embodiments, which are not limited by the following examples.
The conference tablet has the functions of various devices such as a curtain, an electronic whiteboard, a sound, a computer, a remote conference terminal and the like, and is often applied to scenes such as conference office, education training and the like. The conference tablet comprises a touch screen and a main control device, wherein the main control device can be a sub-device including a CPU in the conference tablet, a user can touch the touch screen through a finger or other objects, and the touch screen generates a corresponding control instruction according to the sensed touch operation and inputs the control instruction to the main control device in the conference tablet so as to control the main control device to execute corresponding operation, such as opening a designated application program, playing a video and the like.
Fig. 1 shows a schematic diagram of an input subsystem provided by an embodiment of the invention, where the schematic diagram includes a device driver layer 110, a core layer 120, an event driver layer 130, and an application processing layer 140.
Wherein the core layer 120 is used to interface the device driver layer 110 and the event driver layer 130, the device driver layer 110 is used to interface the touch screen and the input subsystem, and the event driver layer 130 is used to interface the application processing layer 140 and the input subsystem. The arrow of the thick solid line in the figure represents the transmission direction of the control command, and the conference tablet can convert the control command input by the touch pad into a standard event meeting the preset standard by using the input subsystem, and uniformly input the standard event into the application program through the event driving layer so as to control the application program to respond to the input control command.
The input of the application program can be unified through the input subsystem, so that the input of the application program is a standard event no matter what input device is used for inputting the control command. The development cost and the operation and maintenance cost of the application program can be effectively reduced.
However, the device driver layer 110 of the input subsystem can only interface with the USB driver, and thus only the input device accessing the master device through the USB interface can access the input subsystem. Due to design requirements, for example, due to cost considerations, the USB interface of the master device is limited, and therefore, the touch screen may not be able to access the master device through the USB interface, but only can access the master device through a serial port. Resulting in the touchscreen not being able to interface with the device driver layer 110 of the input subsystem, i.e., the touchscreen not being able to interface with the input subsystem. Therefore, it is difficult to convert the manipulation instruction input by the touch screen into a standard event, and therefore, an application program in the conference tablet may need to configure a corresponding driver program for the touch screen, otherwise, a user cannot control the conference tablet to perform a part of operations through the touch screen.
Based on this, the embodiment of the present invention provides a method for converting control data, which can be applied to any master control device supporting access to an input device, such as a processing module in a mobile phone, a master control device in a conference tablet, a computer, and the like, where the master control device includes a serial port and is connected to the input device through the serial port. The method may be as shown in fig. 2, comprising:
s201, when the control data sent by the input device is received through the serial port, the control data is intercepted and cached.
And S202, after at least one data packet is completely cached, sequentially aiming at each completely cached data packet, converting the control data included in the data packet into a standard event meeting a preset standard by utilizing the event drive of the input subsystem.
By adopting the embodiment, the control data transmitted by the serial port can be intercepted, the control data capable of completely representing the control instruction can be obtained in a cache mode, and the control data is converted into the standard event by utilizing event driving, so that the control instruction input from the serial port is accurately converted into the standard event. The corresponding driver does not need to be configured for the application program aiming at the input equipment accessed from the serial port, and the development, operation and maintenance costs of the application program are effectively reduced.
In S201, the manipulation data is generated by the input device after sensing the operation, and the manipulation data generated by the same operation belongs to the same data packet. The input device may be different types of input devices according to application scenarios, and may be, for example, a mouse, a keyboard, a touch screen, a remote control stick, and the like. And the input device should be one that can interface with a serial port. Since the serial port transmits data byte by byte, and the single byte of the manipulation data cannot represent the operation for generating the manipulation data, the manipulation data needs to be buffered to obtain the manipulation data capable of completely representing the operation for generating the manipulation data.
In a possible embodiment, when data is received, it is determined whether header information of a data packet to which the data belongs matches identification information of a serial port, and if the header information matches the identification information, it is determined that the received data is control data input by an input device through the serial port, the control data is intercepted, and the control data is cached. The method may include setting a hook function in the serial port driver, where the hook function is used to detect whether header information of a data packet to which the received data belongs matches identification information of the serial port, and if the header information matches the identification information, determining that the received data is control data input by the input device through the serial port, and intercepting the control data.
It can be understood that the header information of a data packet often includes information indicating an interface that receives the data packet, so that if the header information matches the identification information of the serial port, the data packet may be considered to be received through the serial port, and data belonging to the data packet may be considered to be manipulation data input by the input device through the serial port.
Intercepting the manipulation data may mean rejecting transmission of the manipulation data to a downstream in a preset service logic, and the preset service logic is different according to different application scenarios, so that objects referred to by the downstream may be different. Or copying the control data and continuing to transmit the control data to the downstream in the preset business logic.
In a possible embodiment, when the header of the data packet is received, the header information carried in the data packet is analyzed, whether the header information is matched with the identification information of the serial port or not is judged, and if the header information is matched with the identification information of the serial port, all data in the data packet are considered to be control data received through the serial port and sent by the input device.
In S202, it may be determined that all the handling data in a data packet has been completely buffered when the packet end of the data packet is received. Because the operation data generated by the same operation belongs to the same data packet, after a data packet is completely cached, the operation data included in the data packet in the cache can completely represent the operation for generating the operation data, and therefore the operation data included in the data packet can be converted into the standard event which meets the preset standard by utilizing the event drive of the input subsystem.
After the standard event is obtained, the standard event can be continuously triggered through event driving so as to control the application program to respond to the control data input by the input equipment through the serial port. In some application scenarios, S201 and S202 may be performed synchronously, that is, the manipulation data in the cache is converted into a standard event while the manipulation data is cached.
The handling data needing to be cached may be more and more as the caching of the handling data proceeds, but the space of the cache is often limited, and if all the handling data needing to be cached cannot be cached, the handling data will be lost.
Based on this, an embodiment of the present invention provides a cache management method, which may be as shown in fig. 3, where fig. 3 is a schematic flow chart of the cache management method provided in the embodiment of the present invention, and the method may include:
s301, when the control data sent by the input device is received through the serial port, the control data is intercepted and cached in a unit indicated by the writing identifier in the preset annular cache region.
The unit from the writing identifier to the reading identifier in the preset ring buffer is an idle unit, the idle unit refers to a unit into which new control data can be written, the idle unit may store data or may not store data, and if the idle unit stores data, the idle unit may overwrite new control data to the idle unit when writing the new control data into the idle unit.
The circular buffer area may be as shown in fig. 4, where the unit from the beginning of the write identifier to the end of the read identifier refers to a unit from the beginning of the write identifier to the end of the read identifier along the positive direction of the circular buffer area, and for convenience of description, it is assumed that the positive direction of the circular buffer area is the clockwise direction in fig. 4, and then the unit 4, the unit 5, the unit 6, and the unit 1 in the circular buffer area shown in fig. 4 are idle units.
The write identifier indicates a preset initial unit in the ring buffer area when the write identifier is initial, and updates the unit indicated by the write identifier when one data packet is completely buffered, wherein the unit indicated by the write identifier after updating is changed into a unit which can store the data packet next to the unit indicated before updating. The preset initial unit may be different according to different application scenarios, and may be, for example, the unit 1 shown in fig. 4. The next unit is the next unit in the forward direction of the ring buffer, and taking the example shown in fig. 4 as an example, the next unit of the unit 4 that can store the data packet is the unit 5.
And S302, sequentially aiming at the data packets cached in the units indicated by the read identifications, converting the control data included in the data packets into standard events meeting the preset standard by using the event drive of the input subsystem.
The reading identifier indicates a preset initial unit at the initial time, and the unit indicated by the reading identifier is updated after the standard event is constructed, wherein the unit indicated by the reading identifier after the updating is the next unit which stores the unconverted control data from the unit indicated before the updating. By adopting the embodiment, the unit which stores the unconverted control data can be accurately represented in real time by setting the read identifier and the write identifier, so that the unit which does not store the unconverted control data is released in time, the limited cache space is fully utilized, the control data is stored as much as possible, and the possibility of losing the control data is reduced.
A description will be given below of a process for converting the control data in the same data packet into the standard event, and referring to fig. 5a, fig. 5a is a schematic flow diagram of a method for converting the control data into the standard event according to an embodiment of the present invention, where the method may include:
s501, analyzing the operation data included in the data packet to obtain at least one valid operation information.
Wherein each valid operation information is used to indicate a sub-operation in the operation of generating the data packet. Taking the input device as a touch screen as an example, the valid operation information may be used to indicate sub-operations such as a pressing sub-operation, a drawing sub-operation, and a lifting sub-operation. The pressing sub-operation is used for indicating that a user presses one or more touch points on the touch screen by using a finger or other objects, the drawing sub-operation is used for indicating that the user slides on the touch screen according to a certain track by using the finger or other objects, and the lifting sub-operation is used for indicating that the user removes the finger or other objects pressed on the touch screen. Taking the input device as a mouse as an example, the valid operation information may be used to indicate a left click sub-operation, a move sub-operation, a right click sub-operation, a scroll wheel sub-operation, and the like.
And S502, converting all effective operation information into standard events meeting preset standards by using the event drive of the input subsystem.
Take the input device as a touch screen as an example. It will be appreciated that a full gesture operation typically begins with a press sub-operation to end with a lift sub-operation. Therefore, all the valid operation information from the valid operation information (hereinafter, referred to as the press valid operation information) indicating the press sub-operation to the next valid operation information (hereinafter, referred to as the lift valid operation information) indicating the lift sub-operation can be converted into the same standard event. The rule of the conversion may be different according to different application scenarios, and for example, assuming that three continuous effective operation information are effective operation information for representing a pressing sub-operation, effective operation information for representing a drawing sub-operation (hereinafter, drawing effective operation information), and effective operation information for representing a lifting sub-operation, the three continuous effective operation information may be converted into the same standard event. In another possible embodiment, each valid operation information may be converted into a standard event.
It can be understood that, due to loss of the manipulation data or other reasons, the effective operation information obtained by the parsing may not be complete, so that the converted standard event may not be well matched with the operation sensed by the input device, so that the business operation performed by the main control device is different from the operation expected by the user.
Based on this, in an application scenario where the input device is a touch screen, in a possible embodiment, the method for converting the manipulated data into the standard event may also be as shown in fig. 5b, and between S501 and S502, the method may further include:
and S503, if the at least one piece of effective operation information comprises the drawn line effective operation information and does not comprise the pressing effective operation information aiming at the drawn line point, adding the pressing effective operation information aiming at the drawn line point in the at least one piece of effective operation information.
The drawing point is a touch point aimed at by the drawing sub operation on the input equipment. As discussed above, a full gesture operation is typically initiated by a press sub-operation to complete a lift sub-operation. Therefore, if the effective operation information for drawing the line is included in the at least one piece of effective operation information, the touch screen is indicated to sense a line drawing sub-operation, and the track along which the line drawing sub-operation is performed starts from the line drawing point, so that there should be pressing effective operation information for the line drawing point, and if there is no pressing effective operation information for the line drawing point, it can be considered that one piece of pressing effective operation information for the line drawing point is lost. Therefore, the lost valid operation information can be complemented.
By adopting the embodiment, the possibility of incomplete effective operation information can be effectively reduced.
As described above, a complete gesture operation usually starts with a pressing sub-operation and ends with a lifting sub-operation, so if the valid operation information for indicating the lifting sub-operation is lost, the corresponding valid operation information for indicating the pressing sub-operation cannot indicate the complete gesture operation together with other valid operation information, and therefore is not correctly converted into a standard event, so that the valid operation information for indicating the pressing sub-operation is not normally responded.
Based on this, in a possible embodiment, as also shown in fig. 5c, after S502, the method may further include:
s504, if the press effective operation information which is not converted yet exists, the control application program responds to the press effective operation information.
In the application scenario, since the press valid operation information cannot be normally converted into the standard event, the application program may be controlled to forcibly respond to the press valid operation information by converting the valid operation information into an up event.
The execution timing of S504 may be immediately after S502, or may be after a preset time period after S502 is executed. For example, a regularly executed background process may be set, and each time the preset time node is reached, the background process executes S504.
By adopting the embodiment, the possibility that the effective operation information is not responded by the application program can be reduced, so that the user can better control the main control equipment through the input equipment.
