Description
Technical field
The present invention relates to automotive entertainment system, be specifically related to the automotive entertainment system with automatic arousal function.
Background technology
Automobile is generally all equipped with automotive acoustics, with in the automotive acoustics of movement, have employed two kinds of modes and realizes automatically inhaling dish, read dish.One is mechanical type, and take video disc mode of touching to transmit information, realize automatically inhaling dish, another kind is Photoinduction type, takes photoelectric tube induction mode to realize automatically inhaling dish, reading the function of dish.These two kinds of modes all must could realize above function under the state of normal boot-strap.
Existing car audio system does not have automatic arousal function, and car audio system utilization factor is low, can not meet consumers' demand.Therefore, on the basis of basic function retaining former car audio system, being further improved by car audio system, to realize the intelligent functions automatically waken up, can farthest meeting consumers' demand, is that the one of prior art is improved.
Summary of the invention
The object of the invention is, solve the problem that current car audio system does not have automatic arousal function, by cpu control circuit, video disc can be inserted under the state of shutdown, and send instruction by CPU, realize Auto Power On, read video disc.Along with increasing automobile enters average family, the demand of user is also more and more diversified, the automatic arousal function of automobile audio is become win the additional function that more consumers like.
The present invention realizes above-mentioned purpose and takes following technical scheme:
A kind of automotive entertainment system, comprises the photoelectric tube connected successively, CPU, power supply, movement and voice control module; Memory power supply is also comprised between described photoelectric tube and CPU; CPU control linkage movement; Described power supply connects ACC shelves.
Further, described power supply is provided with the circuit of NPN type triode composition, and the circuit of described NPN type triode composition, takes to power at transistor base, utilize the principle of emitter conducting, connect ACC shelves.
Further, described movement comprises motor driving chip and audio decoder chip.
When described photoelectric tube senses video disc, memory power supply output low level, be sent to CPU by I/O port, CPU receives low level, converts built-in command to, is sent to power supply, and power supply connects the energising of ACC shelves; Then CPU sends out high level to movement, realizes reading dish.
For better realizing goal of the invention, described CPU is CPU S3C84I9; Described motor driving chip is AM5766FM; Described audio decoder chip is SAMSUMG S5L8035.
Memory power detecting photoelectric tube signal, when there being video disc to insert optical disc enter port, photoelectric tube senses video disc, and memory power supply displacement low level, CPU driving power discrete component carries out start work, and reads video disc.
The invention has the beneficial effects as follows, by memory power supply and cpu control circuit, video disc can be inserted under the state of OFF shelves, and send instruction by CPU, realize Auto Power On, read video disc wakeup of automotive entertainment systems.Solve current car audio system when not inserting car key and forwarding ACC shelves shelves to, not there is the problem of arousal function.

Fig. 2 is utility model works principle flow chart.
Fig. 3 is the schematic diagram of the utility model CPU control loudspeaker.
Embodiment
As shown in Figure 1, BATTERY (memory power supply) is all the time in "on" position, and when photoelectric tube does not sense video disc, signal keeps original state.When described photoelectric tube senses video disc, now BATTERY Signal permuting low level, be sent to CPU S3C84I9 by I/O port, CPU S3C84I9 receives this low level, converts built-in command to, being sent to power unit. power unit is mainly the circuit of NPN type triode composition, take to power at transistor base, utilize the principle of emitter conducting, connect ACC shelves, and start shooting, and power to successively each operating circuit.
As shown in Figure 2, CPU S3C84I9 continues to send out high level to movement, is first sent to described motor driving chip AM5766FM, loading motor FF030PK11160 works, and now loading motor rotates forward, and drives Load System pinion rotation, video disc is sent into movement, forms pressure dish.When video disc enters pallet completely, load switch and detect, whether video disc puts in place.If video disc does not put in place, now load switch and send low-voltage to drive motor FF030PK11160, drive motor FF030PK11160 reverses, and exits video disc.If video disc puts in place, described loading switch sends high voltage to CPU S3C84I9 by I/O port, and video disc rotates, and shaven head tracks, and now just can normally read video disc information.The information that shaven head reads can be sent to audio decoder chip SAMSUMG S5L8035 and decode.
As shown in Figure 3, the digital signal tentatively obtained of decoding becomes simulating signal through A/D converter, and filtered by low-pass filter, the simulating signal of final output divides two-way, volume control signal is sent in described CPU S3C84I9, sound signal is input in audio-frequency power amplifier TDA7388, volume control chip PT2313 is controlled volume accordingly by described CPU S3C84I9, now the external loudspeaker matched of described audio-frequency power amplifier TDA7388, realizes the broadcasting of sound.
