Embodiment
As shown in Figure 7, car borne GPS navigation of the present invention, entertainment systems comprise: system control chip 1, navigational system 2, DVD player 3, radio 5, input media 6, audio frequency handover module 4, digital power amplifier 7 and supply unit 10; The annexation of each module is as follows:
Briefly introduce each functions of modules of vehicle GPS Voice Navigation of the present invention, entertainment systems below:
Input media 6: this device is used to import user instruction, and present embodiment adopts touch-screen to come input instruction.Certainly, also other input mode be can adopt, as the display screen of button or telepilot etc. had.
DVD player 3: comprise DVD decode system and DVD player core; Wherein the DVD decode system provides the ATAPI interface of system and DVD player core, and system control chip 1 will pass to the DVD decode system from the order that input media obtains by communication signal.If the amusement video disc is the reporting system control chip then, make system enter the play mode that entertainment mode is entertain mem signal such as DVD/VCD/CD, the DVD decode system number is sent to the audio frequency handover module with sound; If the navigation data video disc is the reporting system control chip then, make system enter navigation mode, the DVD decode system is sent to navigation feature CPU with data simultaneously.
Navigational system 2: system control chip 1 will pass to navigational system 2 from the order that input media obtains by communication signal, the function of control navigational system.Navigational system 2 receives navigation data and calculates the realization navigation feature from the decode system of DVD player 3.Navigational system is sent to sound effect control and audio frequency handover module with the navigation speech signal.
Radio receiver module 8: this module work of system control chip 1 control, realize radio function.The radio sound signal is sent to sound effect control and audio frequency handover module.
Sound effect control and audio frequency handover module 5: with the navigating audio signal, the sound signal that DVD entertain mem signal or radio transmit is sent to digital power amplifier under the control of system control chip.Under the situation that navigational system and radio are worked simultaneously, the audio frequency handover module can switch output navigation speech signal or radio receiver signal, when switching is output as radio receiver signal, the audio frequency handover module can be in time, as: when calculating vehicle from 100 meters of junction aheads, (can set various indicating modes) according to different situations, automatically switch to the navigation speech function, to remind the driver to note, after prompting finishes, switch to play mode before again.System control chip is also realized the control to the sound effect control chip.
Digital power amplifier 7: realize the power amplification of sound signal.
Power-supply system 10:, realize the control of power supply for each functional module provides power supply.
Below in conjunction with Fig. 8, the workflow of concrete introducing system control chip 1:
System control chip receives the user instruction that transmits from input media, sends control signal according to user instruction to corresponding navigation system, DVD player or radio, particularly:
If be navigation command, then system control chip sends instruction to the DVD decode system, as being the navigation video disc in the DVD player, DVD decode system reporting system control chip, navigational system is under the control of system control chip, receive navigation data from the DVD decode system, export the navigating audio signal to audio frequency handover module and power amplifier as calculated, realize Voice Navigation by output device; If video disc is the amusement video disc, DVD decode system reporting system control chip, and under the control of system control chip, export entertainment audio signal to the audio frequency handover module, and by the output device output audio signal.It is to be noted, the navigational system of present embodiment is under the normal situation of route or travel by vehicle, just can navigate according to the navigation information in the DVD player navigation video disc, but when vehicle operating departs from navigation direction, only the information according to the navigation video disc will produce deviation, this moment, system can be used in combination the mode of satnav, redefined the residing correct orientation of vehicle, and recomputated navigation data according to positioning result.
If user's input is the amusement order, system control chip will be according to concrete AM/FM, DVD/VCD/CD Play command mode, send steering order to corresponding radio receiver module, DVD player interface, described radio, the DVD player interface arrives audio frequency handover module and power amplifier according to control command with audio signal output, and the audio frequency handover module can switch the output multipath audio signal, and by the output device output audio signal.
Each module interface circuit figure of the embodiment of the invention please refer to Fig. 1 to shown in Figure 6.Wherein, the trend of the input/output signal of each interface circuit can be with reference to this signal name and subsequent numeral among the figure, the corresponding page number of this numeral Figure of description.Just the signal of respective name is connected in the corresponding page number of this signal and Figure of description.For example, the pin one 1 of VU8 connects signal " IRDATB 4 " among Fig. 5, represents that the signal " IRDATB " among the 4th page of Fig. 4 of itself and Figure of description links to each other, and promptly links to each other with the pin 8 of JG1 among Fig. 4.Therefore the signal trend of each interface is no longer repeated in instructions among the figure.
