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 some, but not all, embodiments of the present application. 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.
In a first embodiment of the present application, please refer to fig. 1, which is a flowchart illustrating steps of a broadcast audio accompanying text display method based on an OLED window according to the first embodiment of the present application; as shown, the OLED window based broadcast audio accompanying text display method S includes the following steps S1 to S3. Wherein:
step S1, storing the text information of all broadcast audio in the OLED window. And connecting the OLED window with the vehicle-mounted PIS system, and storing text information corresponding to all broadcast audios of the vehicle-mounted PIS system in the OLED window.
Specifically, the OLED window is communicated with the vehicle-mounted PIS through an Ethernet interface, and before a train runs, broadcast audio files and text information of all broadcast contents in the vehicle-mounted PIS are stored in the intelligent transparent OLED window in a one-to-one mode.
Step S2 is to store the broadcast audio and the text information and text information display control command corresponding to the broadcast audio as a set. And formulating a text information display control instruction corresponding to each broadcast audio in the control system of the OLED car window, and storing each broadcast audio, and the text information display control instruction corresponding to the broadcast audio as a group.
Specifically, according to a control protocol specified by the vehicle-mounted PIS system, a text information display control instruction corresponding to each broadcast audio frequency is formulated in the OLED window system, and the text information, the broadcast audio frequency file and the text information display control instruction corresponding to each broadcast audio frequency are stored as a group.
And step S3, calling corresponding stored data according to the broadcast audio and displaying the corresponding stored data on the OLED window. When the vehicle-mounted PIS system sends broadcast audio to the vehicle-mounted loudspeaker, the vehicle-mounted PIS system simultaneously sends a broadcast voice control instruction corresponding to the broadcast audio to the OLED window, and the OLED window displays text information corresponding to the broadcast audio on the OLED display screen according to the broadcast voice control instruction.
Specifically, in the running process of the train, the vehicle-mounted PIS system sends broadcast audio to an in-train loudspeaker and simultaneously sends a broadcast voice control instruction corresponding to the broadcast audio to an OLED window through an Ethernet interface. After a machine core board in the OLED car window receives the broadcast voice control instruction, the received broadcast voice control instruction is converted into a searching text information display control instruction according to a preset vehicle-mounted PIS system control protocol, the searching text information display control instruction is matched with all stored text information display control instructions, after the searching text information display control instruction is recognized to be completely matched with the corresponding broadcast voice control instruction, text information corresponding to the broadcast voice control instruction is called and sent to an OLED display screen to be displayed on the OLED display screen, and therefore when the PIS voice broadcast of the train is carried out, passengers can know the related contents of the broadcast through the OLED car window.
Furthermore, after the OLED car window recognizes that the searched text information display control instruction is completely matched with the corresponding broadcast voice control instruction, the core board of the OLED car window simultaneously calls the broadcast audio corresponding to the broadcast voice control instruction, sends the broadcast audio to the loudspeaker on the OLED car window, and plays the broadcast audio through the loudspeaker, so that when the broadcast text information is displayed on the OLED display screen, the loudspeaker of the OLED car window synchronously plays the corresponding broadcast audio.
In this embodiment, after the above steps S1 and S2, if the vehicle-mounted PIS system performs manual broadcasting, the vehicle-mounted PIS system automatically records the audio, generates an audio file in MP3 format, and sends the audio file to the OLED window, and the OLED window controls a speaker thereon to perform broadcasting after audio analysis. Specifically, the vehicle-mounted PIS system automatically records the artificial voice, generates an audio file in an MP3 format, sends the audio file to a core board of the OLED window through the Ethernet, and after receiving the MP3 audio file, the core board performs audio analysis and controls a window loudspeaker to play. Meanwhile, the OLED window stores the MP3 audio file in the solid state disk, and a user can call the audio file through corresponding keys on the OLED window to play in a circulating mode.
In a second embodiment of the present application, please refer to fig. 2, which is a schematic diagram of a broadcast audio accompanying text display system according to the second embodiment of the present application; as shown, a broadcast audio text display system 1 includes an OLED window 2. The OLED window 2 is connected to an onboard PIS system 3. Specifically, the OLED window 2 is in communication connection with the vehicle-mounted PIS system 3 through the Ethernet, and the vehicle-mounted PIS system 3 sends a broadcast voice control command corresponding to broadcast audio to the OLED window 2 through the Ethernet.
The OLED window 2 includes an OLED display screen 21 and a core board 22. The engine core board 22 stores text information corresponding to all broadcast audio of the vehicle-mounted PIS system 3, and after receiving the broadcast voice control instruction, the OLED vehicle window 2 searches for the text information corresponding to the broadcast voice control instruction and sends the text information to the OLED display screen 21, so that the OLED display screen 21 is controlled to display the text information. In this embodiment, the OLED display 21 has a long strip-shaped display area 211 disposed at the upper end or the lower end thereof for displaying text information.
In this embodiment, referring again to fig. 2, OLED window 2 further includes a speaker 23. The speaker 23 is connected to the core board 22. After receiving the broadcast voice control instruction, the OLED window 2 searches for a corresponding broadcast audio at the same time, and sends the broadcast audio to the speaker 23, so as to control the speaker 23 to play the broadcast audio. In this embodiment, the OLED window 2 further includes a solid state disk 24, the solid state disk 24 is connected to the core board 22, and the solid state disk 24 is used to store an audio file, so that a user can call the audio file through a corresponding key on the OLED window to perform circular playing, but not limited thereto.
In summary, the application provides a broadcasting audio accompanying sound character display method and system based on an OLED (organic light emitting diode) window, when a train broadcasts, text information corresponding to an on-board PIS (picture information system) is synchronously displayed on the OLED window, so that passengers can see the text information corresponding to the train broadcast on the OLED window on the side of the passengers while the train broadcasts, and a loudspeaker of an intelligent transparent OLED window can synchronously play corresponding broadcasting audio.
