Description
Technical Field
The present invention relates to the field of touch technologies, and in particular, to a method and apparatus for converting control data, and a master control device.
Background
The input device may input manipulation instructions to the master device, which the application in the master device recognizes and responds to. Because the input devices are various, such as a mouse, a keyboard, a touch screen and the like, the input modes are different, if a corresponding driver is configured for each different input device in the main control device, so that an application program in the main control device can identify the control instruction input by the different input device, the development and operation cost is too high.
In the related art, to simplify the driving in the host device, an input subsystem (input subsystem) is often provided in an operating system (such as linxu operating system and Android operating system) of the host device. An event driven and a device driven are provided in the input subsystem, and the input subsystem interfaces with the application through the event driven and interfaces with the input device through the device driven. The input subsystem can convert the control instructions input by the input devices into standard events meeting preset standards, and input the standard events to the application program so that the application program executes corresponding business operations, and therefore the application program can identify the control instructions input by different input devices only by being in butt joint with event drivers.
However, the device driver of the input subsystem in the related art can only interface with the USB (Universal Serial Bus ) driver, so that only the input device accessing the master device through the USB interface in the related art can access the input subsystem. For the input devices accessing the main control device through the serial port, the input subsystem cannot be accessed, so that the control instructions input by the input devices cannot be converted into standard events through the input subsystem, and corresponding drivers need to be configured for the application programs aiming at the input devices, so that the development and operation and maintenance costs of the application programs are increased.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the 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 described in the following by way of example, and it will 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 in other embodiments, the standard event construction method provided by the embodiment of the present invention may be applied to other possible application scenarios, which are not limited by the following examples.
The conference flat board has the functions of a plurality of 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 panel comprises a touch screen and a main control device, wherein the main control device can refer to a sub-device comprising a CPU in the conference panel, a user can touch the touch screen through fingers or other objects, and the touch screen generates corresponding control instructions according to the sensed touch operation and inputs the corresponding control instructions to the main control device in the conference panel so as to control the main control device to execute corresponding operations, such as opening a designated application program, playing videos and the like.
Fig. 1 is a schematic diagram of an input subsystem according to an embodiment of the present 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.
The core layer 120 is used for interfacing the device driving layer 110 and the event driving layer 130, the device driving layer 110 is used for interfacing the touch screen and the input subsystem, and the event driving layer 130 is used for interfacing the application processing layer 140 and the input subsystem. In the figure, the arrow with a thick solid line indicates the transmission direction of the control instruction, the conference panel can convert the control instruction input by the touch panel into a standard event meeting a preset standard by using the input subsystem, and the standard event is uniformly input to the application program through the event driving layer so as to control the application program to respond to the input control instruction.
The input subsystem can unify the input of the application program, so that no matter what input device is used for inputting the control instruction, the input of the application program is a standard event. The development cost and the operation cost of the application program can be effectively reduced.
The device driver layer 110 of the input subsystem can only interface with the USB driver and therefore only input devices that access the master device through the USB interface can access the input subsystem. However, due to design requirements, such as cost, the USB interface of the master device is limited, so the touch screen may not be able to access the master device through the USB interface, but only through the serial port. Resulting in the inability of the touch screen to interface with the device driver layer 110 of the input subsystem, i.e., the inability of the touch screen 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 thus an application program in the conference panel may need to configure a corresponding driver for the touch screen, otherwise, a user cannot control the conference panel to perform a partial operation through the touch screen.
Based on this, the embodiment of the invention provides a control data conversion method, which can be applied to any main control equipment supporting access to input equipment, such as a processing module in a mobile phone, a main control equipment in a conference flat board, a computer and the like, wherein the main control equipment comprises a serial port and is connected with the input equipment through the serial port. The method may, as shown in fig. 2, comprise:
s201, intercepting the manipulation data and caching the manipulation data whenever the manipulation data sent by the input device is received through the serial port.
S202, after at least one data packet is completely cached, aiming at each completely cached data packet in sequence, using event driving of an input subsystem to convert control data included in the data packet into standard events meeting preset standards.
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 is obtained in a buffer mode, and the control data are converted into standard events by utilizing event driving, so that the control instruction input from the serial port is accurately converted into the standard events. The method and the device have the advantages that corresponding drivers are not required to be configured for the application program aiming at the input equipment accessed from the serial port, and development and operation cost of the application program is 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 belong to the same data packet. The input device may be different types of input devices according to application scenes, for example, a mouse, a keyboard, a touch screen, a remote control lever, and the like. And the input device should be one that is capable of interfacing with a serial port. Since serial data is transferred byte by byte, and a single byte of manipulation data cannot represent the operation of generating the manipulation data, the manipulation data needs to be cached to obtain the manipulation data which can completely represent the operation of generating the manipulation data.
In a possible embodiment, each time data is received, it may be determined whether header information of a data packet to which the data belongs matches with identification information of a serial port, if the header information matches with the identification information, it is determined that the received data is control data input by an input device through the serial port, and the control data is intercepted and cached. The hook function is used for detecting whether the packet header information of a data packet to which the received data belongs is matched with the identification information of the serial port or not, if the packet header information is matched with the identification information, the received data is determined to be control data input by the input device through the serial port, and the control data is intercepted.
It will be understood that the header information of a data packet often includes information indicating an interface that receives the data packet, so if the header information matches with the identification information of the serial port, the data packet may be considered to be received through the serial port, and the data belonging to the data packet may be considered to be control data input by the input device through the serial port.
Intercepting the control data may mean refusing to transmit the control data to a downstream in the preset business logic, and the preset business logic is different according to different application scenarios, so that the object referred to by the downstream may be different. It may also mean copying the manipulation data and continuing to transmit the manipulation data downstream in the preset business logic.
In a possible embodiment, when the packet header of the data packet is received, analyzing the packet header information carried in the data packet, judging whether the packet header information is matched with the serial port identification information, and if the packet header information is matched with the serial port identification information, considering all data in the data packet as control data sent by the input device received through the serial port.
In S202, it may be determined that all manipulation data in a data packet has been completely buffered when the end of the data packet is received. Because the operation data generated by the same operation belong to the same data packet, after one data packet is completely cached, the operation data included in the data packet in the cache can completely represent the operation of generating the operation data, so that the operation data included in the data packet can be converted into standard events meeting the preset standard by using event driving of the input subsystem.
After the standard event is obtained, the standard event can be triggered continuously through event driving so as to control the application program to respond to the control data input by the input device through the serial port. In some application scenarios, S201 and S202 may be performed synchronously, i.e. the manipulation data in the buffer is converted into standard events while the manipulation data is buffered.
As the process of caching the manipulation data, more and more manipulation data need to be cached may be performed, but the space of the cache is often limited, and if all manipulation data needing to be cached cannot be cached, the loss of the manipulation data will be caused.
Based on this, the embodiment of the present invention provides a cache management method, which may be shown in fig. 3, and fig. 3 is a schematic flow diagram of the cache management method provided by the embodiment of the present invention, and may include:
s301, intercepting control data and caching the control data in a unit indicated by a writing identifier in a preset annular cache area when the control data sent by the input device are received through a serial port.
The unit from the writing identification to the reading identification in the preset ring buffer area is an idle unit, the idle unit refers to a unit capable of writing new control data, the idle unit may or may not store data, and if the idle unit stores data, the new control data can be rewritten into the idle unit when the new control data is written into the idle unit.
The ring buffer may be as shown in fig. 4, and the units from the start of writing to the start of reading of the identifier refer to the units from the start of writing to the start of reading of the identifier along the positive direction of the ring buffer, and for convenience of description, if the positive direction of the ring buffer is clockwise in fig. 4, the units 4, 5, 6, and 1 in the ring buffer shown in fig. 4 are idle units.
The write identifier initially indicates a preset initial unit in the ring buffer, and updates the unit indicated by the write identifier every time one packet is completely buffered, the updated unit indicated by the write identifier changes to the next unit that can store a packet starting from the unit indicated before the update. The preset initial unit may be different according to application scenarios, and may be, for example, unit 1 shown in fig. 4. The next cell is the next cell in the forward direction of the ring buffer, as shown in fig. 4 for example, the next cell of cell 4 that can store a packet is cell 5.
S302, aiming at the data packet cached in the unit indicated by the read identifier, converting the control data included in the data packet into a standard event meeting a preset standard by using event driving of the input subsystem.
The read identifier initially indicates a preset initial unit, and each time the unit indicated by the read identifier is updated after a standard event is constructed, the unit indicated by the read identifier after updating is the next unit which stores unconverted control data from the unit indicated before updating. By adopting the embodiment, the unit storing unconverted operation data can be accurately represented in real time by setting the read identifier and the write identifier, so that the unit not storing the unconverted operation data is released in time, the limited cache space is fully utilized, the operation data is stored as much as possible, and the possibility of losing the operation data is reduced.
The following will describe the process of converting the manipulation data in the same data packet into the standard event, and fig. 5a may be referred to, where fig. 5a is a schematic flow diagram of a method for converting manipulation data into the standard event according to an embodiment of the present invention, and may include:
s501, analyzing the control data included in the data packet to obtain at least one piece of effective operation information.
Wherein each valid operation information is used to represent a sub-operation in the operation that generated the data packet. Taking the input device as a touch screen for example, the effective operation information may be used to represent sub-operations such as a pressing sub-operation, a drawing sub-operation, a lifting sub-operation, and the like. 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 by using the finger or other objects according to a certain track, 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 for example, the effective operation information may be used to represent a left click sub-operation, a move sub-operation, a right click sub-operation, a scroll wheel sub-operation, and the like.
S502, converting all effective operation information into standard events meeting preset standards by using event driving of an input subsystem.
Take the example of an input device as a touch screen. It will be appreciated that a complete gesture operation typically begins with a press sub-operation and ends with a lift sub-operation. Therefore, it is possible to convert all the effective operation information from the effective operation information (hereinafter referred to as pressing effective operation information) for representing the pressing sub-operation to the effective operation information (hereinafter referred to as lifting effective operation information) for representing the next lifting sub-operation into the same standard event. The conversion rule may be different according to the application scenario, and for example, assuming that three pieces of continuous effective operation information are effective operation information for representing a pressing sub-operation, effective operation information for representing a drawing sub-operation (hereinafter referred to as drawing effective operation information), and effective operation information for representing a lifting sub-operation in this order, the three pieces of 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 appreciated that due to loss of control data or other reasons, the effective operation information obtained by parsing may be incomplete, so that the standard event obtained by conversion may not be well matched with the operation sensed by the input device, so that a certain difference exists between the business operation executed by the main control device and the user expectation.
Based on this, in an application scenario where the input device is a touch screen, in a possible embodiment, the method for handling data to standard event may also be as shown in fig. 5b, and between S501 and S502, further include:
S503, if the at least one piece of effective operation information includes the line drawing effective operation information and does not include the pressing effective operation information for the line drawing point, adding the pressing effective operation information for the line drawing point to the at least one piece of effective operation information.
The line drawing point is a touch point for line drawing sub operation on the input device. As with the previous analysis, a complete gesture operation is typically initiated with a press sub-operation and terminated with a lift sub-operation. Thus, if at least one valid operation information includes valid operation information for drawing a line, it means that the touch screen senses a sub-operation of drawing a line and a trajectory along which the sub-operation of drawing a line is started from a point of drawing a line, and thus there should be one valid operation information for pressing the point of drawing a line, and if there is no valid operation information for pressing the point of drawing a line, it may be considered that one valid operation information for pressing the point of drawing a line is lost. Thus, 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 is usually initiated by a pressing sub-operation and ends with a lifting sub-operation, so if the effective operation information for representing the lifting sub-operation is lost, the effective operation information for representing the pressing sub-operation corresponding to the effective operation information cannot be combined with other effective operation information to represent the complete gesture operation, and thus is not correctly converted into a standard event, so that the effective operation information for representing the pressing sub-operation is not normally responded.
Based on this, in one possible embodiment, as shown in fig. 5c, after S502, the method may further include:
S504, if there is press valid operation information that has not been converted yet, the control application responds to the press valid operation information.
In the application scenario, since the pressing effective operation information cannot be normally converted into a standard event, the effective operation information may be converted into an up event to control the application program to forcibly respond to the pressing effective operation information.
The execution timing of S504 may be executed immediately after S502 or after a preset period of time after S502. For example, a background process for timing execution may be set, and S504 is executed by the background process every time a preset time node is reached.
By adopting the embodiment, the possibility that the effective operation information is not responded by the application program can be reduced, so that a user can better control the main control device through the input device.
