Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Fig. 1 is a flowchart illustrating a method for assisting language learning according to an embodiment of the present application. The method of FIG. 1 is performed by a computing device, such as an AIS terminal, and other AIS onboard equipment. As shown in fig. 1, the AIS interactive operation processing method includes the following contents.
110: and detecting and receiving an interactive operation instruction of a user on a user interface.
Specifically, the user interface may be an AIS communication interface displayed by the AIS terminal device, and the AIS communication interface is configured to receive an interactive operation instruction of a user.
The interoperation instruction may be an operation by a contact object (e.g., a finger). The interactive operation command may be operated by a control (e.g., a cursor or a mouse). The control method for generating the interactive operation instruction is not particularly limited in the embodiments of the present application. And, the interoperation instruction may be to select content presented in the user interface, for example, to click on the AIS function module. The interactive operation command may also be selected through a preset gesture, for example, a circular gesture is input on the interface to perform corresponding command movement.
The method for detecting and receiving the interactive instruction may be that after the interactive instruction of the user is generated, the interactive instruction is used as a trigger operation to execute a corresponding operation, or a background continuously scans a user interface at a predetermined time interval to detect and receive the interactive operation instruction of the user. For details of the detection instruction, reference is made to the following description of the embodiments, which are not repeated herein.
120: and determining an AIS processing event corresponding to the interactive operation instruction based on the interactive operation instruction.
Specifically, the types of AIS processing events may include input-type events and output-type events. And the AIS processing event may include a plurality, such as 3, 4, or 5 (see, e.g., fig. 7). It should be understood that the AIS processing events are in a parallel relationship, and for details of the AIS processing events, reference is made to the following description of the embodiments, which is not repeated herein.
Referring to fig. 7, the output type event, i.e., the external driver needs to be called, may include a change display event, and the display driver is called to present changed contents on the display device, for example, the LCD driver is called; the method also can comprise the steps that a printing event calls the USB printing driver; storage events may also be included, invoking the SD driver. The input-type event may include a UART communication event. The input-type event may also include an input event. For details of the AIS processing events, reference is made to the following description of the embodiments, which are not repeated herein.
130: and executing the operation corresponding to the AIS processing event based on the AIS processing event.
Specifically, the corresponding operation is performed based on the AIS processing event. E.g., the detected AIS handling event is a change display event, a display driver (e.g., as shown in fig. 4) is invoked to present the contents of the change display on the user interface.
Therefore, the embodiment of the application can further embody the complete communication system for the AIS processing events by providing a set of complete GUI interface application programs, performing division processing on different AIS processing events and taking the interactive operation of the user as a trigger instruction.
Fig. 2 is a schematic flowchart illustrating a UART communication event of the AIS interactive operation processing method according to an embodiment of the present application. Fig. 2 is an example of the embodiment of fig. 1, and the same parts are not repeated, and the differences are mainly described here. As shown in fig. 2, the method includes the following.
210: the main control module scans the user interface at preset time intervals and waits for the occurrence of the AIS processing event.
Specifically, the main control module may be a control unit that controls the entire GUI interface application control logic (see the flow of fig. 2). Therefore, the main control module 210 can be understood as a main control module of the central processing unit. The central processing unit may also include a processor, such as an Advanced RISC Machine, ARM processor. The ARM processor is a display and control unit of the intelligent navigation equipment and is composed of an ARM chip, a power circuit and a storage chip. The central processing unit may be developed based on a Linux operating system, may also be developed based on a Windows operating system, and may also be developed based on a MaxOS operating system, which is not specifically limited in this embodiment of the present application.
It can be understood that the ARM chip embeds the Linux operating system, and can run a cross-platform development library, such as Qt, thereon, so as to realize interaction with a user and complete information interaction with the underlying module.
220: and judging whether a UART communication event is input.
Specifically, if there is an input of the UART communication event, step 230 is executed, otherwise, step 210 is returned to continue waiting for the occurrence of the UART communication event.
230: and sending the UART communication event into a digital processing module, analyzing the UART communication event to obtain an analysis result and judging whether the analysis result is data information or control information.
Specifically, the digital processing module includes an FPGA core board, and for details of the description of the digital processing module, reference is made to the following description of the embodiment, which is not repeated herein for avoiding repetition.
Parsing the UART communication events may include frame format parsing the UART communication events. The parsing process may be parsing according to a set frame format and obtaining a corresponding parsing result. Wherein, the set frame format can be a new message designed in advance according to actual requirements.
In one example, parsing the UART communication event may make a parsing determination within a protocol stack. Since the AIS system itself has a communication rate of 9.6Kbps, a path is not provided specifically for data information transmission such as navigation information. Therefore, in order to realize the function, on one hand, the waveform generated by the AIS can be used for communication along the original physical layer scheme; on the other hand, the frame structure of the AIS needs to be redefined, and new message types are added, as shown in table 1.
TABLE 1 message 30
The new message 30 occupies 1 AIS standard time slot and can implement point-to-point data transmission. After the ship receives the message, if the 'target ID' field in the message does not match the self ID, the message is discarded. Thus, only the target vessel will process the message.
To ensure that the message is transmitted correctly, a retransmission mechanism may be enabled. After the receiving side finishes receiving, the receiving side needs to perform feedback to the transmitting side (the message structure is shown in table 2), and the transmitting side is informed that the frame sequence number received correctly does not exist. Thereafter, the transmitting party will retransmit the frames until all frames are received correctly or a preset maximum number of retransmissions is exceeded.
Table 2 message 31
| Parameter(s) | Number of bits | Description of the invention |
| Message ID | 6 | Message ID, fixed to 31 |
| Object ID | 20 | Target vessel ID |
| Source ID | 20 | Source ID |
| Number of erroneous frames | 8 | Total number of frames received in error |
| Serial number | 8 | The frame number of message 31, counting from zero |
| Wrong frame number | 106 | Receiving the wrong frame number, requiring retransmission |
| Total number of bits | 168 | Occupying 1 time slot |
Formation communication, e.g., message 32 (see table 3). The message is used for formation communication, and each ship is assigned a formation ID in advance according to the formation to which the ship belongs. After receiving the message 32, comparing whether the target formation ID is consistent with the formation ID of the target formation ID, if not, discarding the message, otherwise, receiving the message, and performing subsequent processing. Further, the message type of the broadcast communication is also taken as the message 32, and the target formation ID is fixed to 0. Any ship receives message 32 and the target formation ID equals 0.
TABLE 3 message 32
The region broadcasts, for example, message 33 (see table 4). The purpose of the area broadcast is to allow ships within a particular area to receive messages. The message format is shown in table 4, the region is a rectangular region, the longitude and latitude 1 in the message represents the lower left corner coordinate of the rectangle, and the longitude and latitude 2 represents the upper right corner coordinate of the rectangle. After receiving the message 33, the ship determines whether it is within the specified rectangular area, and if so, receives the message, otherwise, discards it.
TABLE 4 message 33
| Parameter(s) | Number of bits | Description of the invention |
| Message ID | 6 | Message ID, fixed to 33 |
| Longitude 1 | 28 | Longitude of lower left corner of rectangular region |
| Latitude 1 | 27 | Latitude of lower left corner of rectangular region |
| Longitude 2 | 28 | Longitude of upper right corner of rectangular region |
| Latitude 2 | 27 | Latitude of upper right corner of rectangular region |
| Navigation data frame number | 8 | Total frame number required by this data transmission |
| Serial number | 8 | Frame number, counting from zero |
| Number of active bits | 8 | Effective bit number of navigation data |
| Navigation data | 196 | Navigation data |
| Total number of bits | 336 | Occupying 2 time slots |
The audio file can also be regarded as a kind of data, so that one of the messages 31 to 33 can be selected for communication according to the difference of communication modes.
Distress call, e.g., message 34 (see table 5). The distress call is only transmitted after being pressed by a special key in distress, and the message number is 34. The distress message is a broadcast message which is repeatedly transmitted, and the distress message carries the position information and the basic information of the distress ship.
TABLE 5 message 34
It should be understood that data generated by all of the communication types described above may be recorded and stored by the AIS device (e.g., receiver). If the amount of memory exceeds the maximum limit, the new message will overwrite the oldest message. In addition, a flag may be set for a critical message, and for a message to which the flag is added, the message will not be overwritten by another message. Because the device provides a data transmission interface, the history information stored in the device can be conveniently transmitted to a PC or other devices for reference, statistics and the like.
Therefore, the self-defined communication protocol provided by the embodiment of the application can transmit information such as voice and characters besides realizing basic navigation data communication between the main ship and the auxiliary ship. The broadcasting mode has a common broadcasting function and a self-defined area broadcasting function, and can realize formation transmission and send specific messages to a designated formation.
240: when the analysis result is data information, entering a data processing module for data format conversion to obtain specific data information; and when the analysis result is the control information, entering a command analysis processing module for analysis to obtain the specific control information.
Specifically, the data information and the control information are analyzed to obtain data therein. For example, the parsed specific data information may be "the target ship arrives at the target location approximately 1 month and 30 days 2018". In addition, the embodiment of the present application does not limit the specific form of parsing the data information and the control information.
250: and returning the analyzed data information and the control information to the main control module, and displaying the analyzed data information and the analyzed control information on a user interface by the main control module.
Specifically, the main control module presents the parsed information (the information includes data information and control information), such as text, on the user interface of the AIS terminal device, and prompts the user.
Therefore, the AIS processing event type is enriched, and the real-time performance, reliability and safety of data communication between sailing ships are improved.
According to one embodiment of the application, the digital processing module comprises a Field Programmable Gate Array (FPGA) core board.
In particular, the FPGA core board may be a core unit of a digital processing module. The FPGA core board can comprise a power supply control circuit, an FPGA minimum system and a storage chip. In order to match with peripheral devices, the pin levels of all the expansion interfaces of the FPGA core board can be adjusted correspondingly. The application embodiment does not specifically limit the use model of the FPGA core board, and can be flexibly set according to actual production needs.
Therefore, by arranging the digital processing module, the embodiment of the application can complete functions such as digital modulation in the digital processing module, and the like, thereby ensuring the high efficiency of bottom layer information processing. Fig. 3 is a schematic flow chart illustrating an input event of the AIS interactive operation processing method according to an embodiment of the present application. Fig. 3 is an example of the embodiment of fig. 1, and the same parts are not repeated herein, and the differences are mainly described herein. As shown in fig. 3, the method includes the following.
310: the main control module scans the user interface at preset time intervals and waits for the occurrence of the AIS processing event.
Specifically, step 310 is substantially the same as step 210 in fig. 2, and for details, please refer to the description in fig. 2, which is not repeated herein to avoid repetition.
320: and judging whether an input event is input or not.
Specifically, it is determined whether there is an input event, where the input event may be a key value sent by an external device, for example, a device such as a keyboard, a remote controller, and a mobile phone. If the keyboard is used as an external device, it should be understood that the keyboard in the embodiment of the present application may be a virtual keyboard or a physical keyboard.
The input event may be a key value, such as a number, a letter, a character, etc., that receives a keyboard input. The input event may also be a key value, such as a number, etc., input by receiving a remote control. The embodiment of the present application does not specifically limit the type of the external device.
When it is determined that there is an input event, step 330 is executed.
330: if the input event is sent to the event processing module, whether the input event is keyboard trigger input or remote control trigger input is judged.
Specifically, the input event processing module may determine that the input event is a keyboard trigger input. The input event processing module can also judge that the input event is the remote control trigger input. The input event processing module can also judge that the input event is the trigger input of the mobile phone/the tablet computer. The embodiment of the present application does not specifically limit the determination of the input event processing module.
To facilitate the description of the embodiments of the present application, the present application selects the external device definition as a keyboard or a remote controller.
In one example, when an input event is detected, the input event processing module performs an event for determining whether the input event is triggered by a keyboard or a remote controller. If so, the keyboard driver described in step 340 is executed and invoked. If the input is from the remote controller, the remote controller driver described in step 340 is executed and invoked.
340: if the key value is input by the keyboard, calling a keyboard driver to obtain the key value; and if the key value is input by the remote controller, calling a remote controller drive to acquire the key value.
Specifically, if the key value is obtained by calling the keyboard driver, and if the key value is obtained by calling the remote controller driver, the key value is obtained. The method for calling the keyboard/remote controller to identify the specific input key value is not particularly limited, and different identification schemes can be set according to different external devices.
In one example, the recognition mode may be that the design input character prediction algorithm recognizes a key value. The interface shape of the keyboard or the remote controller, such as the number of keys, the arrangement of the keys and other information, is stored in the system in advance, each key value is set to be a preset effective area, and the corresponding key value area is predicted by receiving the key touch position of the keyboard or the remote controller, so that the corresponding key value is identified.
350: and returning the key values acquired by the keyboard driver and the remote controller driver to the input event processing module, returning the key values to the main control module by the input event processing module, and displaying the key values on the user interface by the main control module.
In particular, the input event processing module may perform different operations at different stages. After the step 340 is executed to obtain the corresponding key value, the obtained key value is input to the input event processing module again. At the moment, the input event processing module returns the acquired key value to the main control module, and the input key value is displayed on the user interface through the main control module, so that the user is prompted.
Therefore, the AIS processing event is enriched, the corresponding key value is displayed on the user interface of the AIS terminal, and the connectivity between the AIS terminal and the external equipment is enhanced.

410: the main control module scans the user interface at preset time intervals and waits for the occurrence of the AIS processing event.
Specifically, step 410 is substantially the same as step 210 in fig. 2, and for details, please refer to the record in fig. 2, which is not described herein for avoiding repetition.
420: it is determined whether there is a change display event input.
In particular, the change display event may be a change of related content displayed on the user interface. Such as changing navigation information displayed on the user interface, or changing the time displayed on the user interface, etc. When it is determined that there is an input for changing the display event, step 430 is performed, otherwise, step 410 is returned to continue waiting for the occurrence of the event.
430: and if the display event is changed, calling a display driver to display.
Specifically, the Display drive may be an LCD drive (liquid Crystal Display). The display driving may also be LCM driving (Liquid composition driving). The display driver may also be an OLED (Organic Light-Emitting Diode), which is not particularly limited in the embodiments of the present application.
Preferably, the embodiment of the present application selects an LCD driver, that is, if a display change event is detected, the LCD driver is called to display the event to be changed.
Therefore, the type of the AIS processing event is enriched, the LCD drive is selected to save the space of the display drive, save electricity and avoid high temperature, and meanwhile the real-time performance and the intuitiveness of event change are enhanced.
