[description of drawings]
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structured flowchart of vehicle video/audio controlling system of the present invention;
Fig. 2 is the control block diagram of vehicle video/audio controlling system of the present invention.
[embodiment]
Below the invention will be further described:
See also Fig. 1, vehicle video/audio controlling system of the present invention mainly comprises six major parts, i.e. power supply, MCU master control system, PC mainboard module, radio receiver module, CD conversion module and power amplifier module.The PC mainboard module has two input ends, is electrically connected with power supply and MCU master control system respectively, is used to provide the mutual of power supply and information; The MCU master control system has two input ends, is electrically connected with power supply and PC mainboard module respectively, and it also has three output terminals, is electrically connected with radio receiver module, CD conversion module and power amplifier module respectively, is used to control the work of these three modules.
As shown in Figure 2, micro-control unit MCU is connected with electronic control unit ECU by the RS232 serial line interface and exchanges information, it also is connected with the PC mainboard module by the RS232 serial line interface, simultaneously, the PC mainboard module links to each other with power supply by the control signal PS-ON of PC power source mainboard with MCU, automobile batteries level BACK general+12V outputs to the power supply place, and power supply is powered to PC mainboard module and micro-control unit MCU again.Micro-control unit MCU controls the startup of motor by control motor-driven IC and closes.Micro-control unit MCU also links to each other with the electronic sound volume tuner by iic bus, thereby further controls four positions of power amplifier.And PC mainboard module, dish box box radio all link to each other with the voice-frequency-multichannel selector switch, by preposition amplification, are connected with the electronic sound volume tuner, thereby carry out the power amplifier output of sound.Automobile ignition switch signal ACC and automobile batteries level BACK+12V power to dish box, radio and MCU respectively.Simultaneously micro-control unit MCU controls radio and dish box, and it with radio between communicate by letter and realize by the SPI agreement, with communicating by letter between the dish box then be adopt the full duplex serial communication mode.
The PC mainboard module is responsible for providing required each power supply by power module, and this power supply adopts the DC-DC mode, be the required operating voltage of PC mainboard module with the voltage transitions of accumulator, and this power supply adopts the control mode of ATX power supply.The PC mainboard module is controlled by ITPS of Automobile Igniting Control system and MCU.The user is after opening automobile ignition switch, vehicle-mounted PC is in the stand-by operation pattern, after the user turns on the power switch, PC begins operate as normal, and miscellaneous equipment also is in the stand-by operation pattern, the user as long as select by button, just can easily be switched on the needed working equipment of arriving when selecting required equipment.When PC uses, when if emergency condition takes place in the user, withdraw from immediately, as long as it is just passable to close ignition switch, this moment, the power supply of PC can not closed immediately, but waiting system has been preserved setting, send shutdown command by system, really powered-down has only when opening ignition switch once more, just can open standby power, this moment, motherboard power supply could operate as normal.When the vehicle-mounted PC of the normal use of user, the operation of switching on and shutting down is the same with desktop PC, so the user handles official business in car, amusement equally can be as convenient on desktop PC.
The AM/FM radio receiver module, control the pattern and the frequency of searching platform by MCU, communication between MCU and the radio is that the agreement by SPI realizes, after communication is set up, radio receiver module just can be finished the work of searching platform and lock platform according to the instruction of MCU, and the radio station of searching out left in 6 channels, the user can freely select the radio station of being liked.Described 6 dish CD converters are also controlled by MCU, and are the mode of the full duplex serial communication of employing between the MCU, finish the switching back and forth of 6 CD dish, can also browse and shuffle simultaneously.Described 4 * 45W power amplifier is that all audio output apparatus are tapped into, and realizes the adjusting of volume, audio, bass and supper bass between the MCU by the communication protocol of IIC, to adapt to the requirement of different user to tonequality.
Except that the PC mainboard module, the working power of other module all is subjected to the control of MCU, and when the user selects different mode of operations, MCU can switch to the corresponding work state and handle corresponding thing.Certainly the user selects by button, under the radio mode of operation when operation A M/FM radio and 6 dish CD converters, the user can be according to the needs of oneself, come channel selection by button, can also automatic channel search, and the radio station that oneself is liked stored.Under 6 dish CD converter mode of operations, the user can be switched each CD dish arbitrarily by button, has saved the trouble of manually changing dish, can also browse the control with shuffle simultaneously.The power amplifier of 4 * 45W mainly is to connect each audio output apparatus, and the sound of each equipment is sent by loudspeaker, gives the user with high-quality seeing and hearing enjoyment.The user when not opening PC, equally can enjoy in the car other that audio-visual equipment brought was happy.Because these device power supply (DPS)s are what to separate with PC mainboard module power supply, so the user does not open PC, equally also can broadcast listening, listen 6 dish CD etc., and this moment radio and 6 dish CD converters and power amplifier information, all pass to PC in real time, if the user opens PC by the serial ports of MCU, the information of this moment just can be seen on display screen, is more convenient for user's operation.
