in the embodiment shown in fig. 1, an intelligent cockpit bluetooth music playing method can be seen, which has the following operation flows: firstly, connecting a terminal device with the Bluetooth of an intelligent cabin, and starting to play Bluetooth music; step two, the intelligent cockpit acquires Bluetooth music information and matches the Bluetooth music information in an online music library through the acquired Bluetooth music information; and step three, adding the song information into the Bluetooth song list according to the matching result, and step four, disconnecting the Bluetooth, and directly playing the Bluetooth song in the intelligent cabin by the user through the Bluetooth song list.
The Bluetooth music in the invention refers to music played by the terminal equipment connected with the intelligent cabin through Bluetooth, and the Bluetooth song refers to Bluetooth music which is cached in the Bluetooth song list and can be played without being connected with the Bluetooth again. After matching through the online music library, an entry of "bluetooth music song list" is generated in the music main interface, and the song list inside is the play record (ordered by time) of bluetooth music. After the Bluetooth song list is generated, the user does not need to connect the mobile phone to play favorite music next time, and the song listening is conveniently realized. According to the invention, by combining the on-line matching and the local cache of the Bluetooth music information, the user can generate corresponding song information on the intelligent passenger cabin only by playing the Bluetooth song once, so that the user experience is improved.
The following further illustrates the technical solutions and effects of the present invention by means of specific examples.
The first step is as follows: terminal equipment connects intelligent passenger cabin bluetooth, and the bluetooth music begins to play to intelligent passenger cabin, and when the bluetooth music begins to play at intelligent passenger cabin, acquires bluetooth music information (song name, singer name), matches this song through bluetooth music information in own online music song library, if match, records the online song ID information of this song.
When matching, matching can be performed by using an accurate matching algorithm, and accurate matching retrieval refers to a retrieval mode that a retrieval word is completely the same as a certain field in a resource library, so that positioning information can be accurately found. Since the matching of the song information is actually performed according to the information of the song name, the singer name and the like of the song, and belongs to character matching, an accurate matching algorithm can be used.
Firstly, music information to be matched is generated according to the information of the music in the online music library, each piece of music generates one piece of music information to be matched, and all pieces of music generate one piece of music information set to be matched. The song information includes song title, genre, track, composition, singer, language, duration, etc. And establishing index information according to the information including the song name, the singer name and the duration information of the Bluetooth song to generate a keyword set.
And taking the keyword set as input, firstly, scanning the music information set to be matched by using a fuzzy algorithm, judging whether the music information set to be matched has the music information to be matched containing the keywords, and if not, indicating that no corresponding Bluetooth song exists in the online music song library. If so, matching is carried out in the selected music information to be matched by using an accurate matching algorithm. When generating the music information set to be matched with the keyword set, the traditional Chinese language is required to be converted into the simplified Chinese language, other languages are required to be converted into the Chinese translation, and Arabic numerals are required to be converted into the Chinese shorthand.
The specific matching process may also classify the songs in the online song library according to the first prefix letter capitalization sequence of the song names, and if there are repeated song names, sort the songs according to the singer names. Firstly, the category of the Bluetooth song is determined according to the capitalization of the first letter of the name of the Bluetooth song, and then whether a corresponding song exists or not is searched under the category.
In the song matching process, if the contents of the online song library are matched, acquiring an online music song ID, recording a Bluetooth music song list, and then listening to the Bluetooth song, wherein Bluetooth is not required to be connected, and the online music song ID can be directly listened through the Bluetooth song list in the intelligent cabin; if the music is not matched with the music, the audio data of the music is cached by adopting a local audio caching method, and meanwhile, the song information is stored.
After matching through the online music library, an entry of "bluetooth music song list" is generated in the music main interface, and the song list inside is the play record (ordered by time) of bluetooth music.
The second step is that: if the Bluetooth music information cannot be inquired in the online music library, the audio data of the music is cached by adopting a local audio caching method, the specific method is that the current Bluetooth music channel is obtained through an audio management channel of an android system, audio stream data (pcm format) is obtained and cached in an internal memory, and when one Bluetooth music is played and meets the following conditions, the music caching is judged to be a complete song:
1. no drag is generated in the playing process of the Bluetooth music interface progress bar of the cabin
2. The actual playing time of the song is consistent with the song duration in the music information.
When the two conditions are met, the audio data cached in the cockpit is judged to be a complete song, and after the song is played, the song is stored in a disk (the name of the song, the name of a singer and time duration information are stored at the same time). If the music is not a complete one, the Bluetooth music buffer is discarded.
In the caching process, setting a pause time threshold and a pause time threshold, stopping caching if the Bluetooth music is paused, discarding the Bluetooth music cache if the pause time exceeds the threshold, and continuing caching if the Bluetooth music is resumed within the pause time threshold; if the pause times of the same Bluetooth music in the same playing exceeds the pause time threshold value, the Bluetooth music cache is discarded. If the pause time is too long, the bluetooth is disconnected or the user does not play music in the current time period, the cache is not stored any more, and the bluetooth cache function is automatically closed. The number of pauses is too long and may affect the integrity of the song, so this bluetooth buffer is discarded.
And only one part of the songs can be selectively recorded according to the requirement through the large-screen interaction of the intelligent cockpit. At this time, the user is required to manually select the starting point and the end point of the acquisition when the audio data stream is acquired, and after the acquisition is finished, the storage cache is manually clicked, so that whether the song is complete or not is not required to be judged, and the song information to be stored is already stored.
The third step: after matching through the above online song library or this time of buffering, an entry of a "bluetooth music song list" is generated in the music main interface, and the song list in the entry is the play record (ordered by time) of bluetooth music.
The fourth step: after the Bluetooth music is generated, the user does not need to connect the mobile phone to play favorite music next time, and can directly use the large-screen interaction (including voice control) of the intelligent cabin to listen to songs in the aspect.
The fifth step: when the user plays new Bluetooth music, the Bluetooth music song list can be kept updated synchronously. Through repeating above-mentioned step, the bluetooth song list is updated in step, expands the bluetooth song list, can directly use the broadcast of intelligent passenger cabin when playing same music once more without connecting the bluetooth to can broadcast at any time.
According to the invention, when the Bluetooth music is played, through the modes of network online song library matching and local audio data caching, a user can generate corresponding song information on the intelligent passenger cabin only by playing the Bluetooth song once, a Bluetooth music song list is created and produced, and a subsequent user can directly play the Bluetooth song at the passenger cabin end (without connecting Bluetooth again), so that the method is very convenient.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
