Summary of the invention
Goal of the invention of the present invention is to provide a kind of song storage means and device of automobile audio, can realize the storage of automobile audio song more easily.
The present invention is based on same inventive concept, have three independent technique schemes:
1, a kind of song storage means of automobile audio, it is characterized in that: decoding unit is decoded to song audio files, under the control of main control chip, decoded audio file is deposited into the FLASH storage chip, carries out the single first storage or the deletion of song.
Decoding unit can be decoded to the song audio files of storing on USB card or the SD card.
Main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected K9F1G08VOM for use.
The decoding unit of movement is decoded to the song audio files of storing on the video disc, under the control of main control chip, decoded audio file is deposited into the FLASH storage chip, carries out the single first storage or the deletion of song.
Main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected MLC 3890 for use.
Be provided with the memory power supply that is in "on" position all the time, the memory power supply connects the photoelectric tube that can discern video disc, and after photoelectric tube identification video disc, the photoelectric tube output signal is to main control chip, and main control chip output control signal is opened the sound equipment power supply, and movement is started.
Select song by button on the sound equipment panel, carry out the storage or the deletion action of single first song.
2, a kind of device of realizing aforementioned automobile audio song storage means, it is characterized in that: the signal output part of USB card or SD card connects decoding unit, and the signal output part of decoding unit connects the FLASH storage chip, and decoding unit is connected with the main control chip communication.
Main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected K9F1G08VOM for use.
3, a kind of device of realizing aforementioned automobile audio song storage means, main control chip is connected with the movement communication, it is characterized in that: the signal output part of decoding unit connects the FLASH storage chip in the movement.
Main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected MLC 3890 for use.
Be provided with the memory power supply that is in "on" position all the time, the memory power supply connects the photoelectric tube that can discern video disc, and the photoelectric tube signal output part connects main control chip, and the main control chip signal output part connects the sound equipment power control unit, thus the startup of control movement.
The beneficial effect that the present invention has:
The present invention realizes the single first storage or the deletion of song by main control chip and special FLASH storage chip, on the basis that keeps existing car audio system basic function, car audio system is further improved,, can farthest meet consumers' demand with the intelligent functions of automatic storage.
The present invention can discern video disc by photoelectric tube, thereby startup movement, the storage of realization song, characteristics with hommization operation and intellectualized operation, strengthened the terseness of operation greatly, and the present invention do not need additionally to increase other hardware devices, but directly utilize the main control chip to control, realize function from software, effectively provide cost savings.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the embodiment of the invention one;
Fig. 2 is the schematic block circuit diagram of the embodiment of the invention two.
Embodiment
Embodiment one:
As shown in Figure 1, the signal output part of sound equipment USB card or SD card connects decoding unit, and the signal output part of decoding unit connects the FLASH storage chip, and decoding unit is connected with the main control chip communication.Wherein, main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected K9F1G08VOM for use, and decoding unit is the MP3 decoding device.
Under USB or SD interface, select song by button on the sound equipment panel, decoding unit is decoded to song audio files, under the control of main control chip, decoded audio file is deposited into the FLASH storage chip, carries out the single first storage or the deletion of song.
Embodiment two:
As shown in Figure 2, main control chip is connected with the movement communication, and the signal output part of decoding unit connects the FLASH storage chip in the movement.Wherein, main control chip is selected TMP 85FS4 for use, and the FLASH storage chip is selected MLC 3890 for use.
Be provided with the memory power supply that is in "on" position all the time, the memory power supply connects the photoelectric tube that can discern video disc, and the photoelectric tube signal output part connects main control chip, and the main control chip signal output part connects the sound equipment power control unit, thus the startup of control movement.
The video disc of packing into, photoelectric tube is sensed video disc, remembers power supply signal displacement low level this moment, and photoelectric tube is sent to main control chip with low level signal, and main control chip receives this low level signal, and the output control signal is opened the sound equipment power supply, and movement is started.Shaven head reads the song audio files of storing on the video disc, the decoding unit of movement is decoded to it, the digital signal that decoding obtains becomes simulating signal through A/D converter, and filter by low-pass filter, main control chip is controlled its output, and the audio files storage that makes output is to the FLASH storage chip, under the CD interface, select song by button on the sound equipment panel, carry out the storage or the deletion action of single first song.
