Description
Automobile industry is present industry the biggest in the world, also is one of mainstay industry of Chinese national economy development.Car is the next new household consumption focus of China, and potential market is huge, and economic benefit is considerable, and the status of automotive electronics in following automobile industry is more and more important.Automobile digitizing, informationization, networking are the inexorable trends of consumer automobile electronics technical development of 21 century, auto navigation, multimedia and internet access system will become the indispensable equipment of 21 century automobile, along with mobile communication technology, computer technology, the development of Internet technology and promoting the use of of gps system, make the mobile automobile can only just can getable message exchange environment before can obtaining in stationary applica-tions such as office and families.These technology and automobile are organically combined the developing direction that has become consumer automobile electronics
The purpose of this vehicle-mounted computer project is ripe already PC technology, mobile communication and network technology, GPS and Computer Multimedia Technology are organically combined, exploitation is towards 21st century, a new generation is the high-tech product that integrates the multifunctional all of broadcast reception, information management, network service, auto navigation and amusement based on the consumer automobile information electric equipment products of open standard, multifunctional all.Accompanying drawing 1 be vehicle-mounted computer mainboard structure figure wherein: central processing unit (1), DVD decoding circuit (2), Ethernet controller (3), interface circuit (4), audio encoding and decoding circuit (5), BIOS circuit (6), NTSC/PAL scrambler (7), terminator (8), composite video output interface (9), composite video input interface (10), serial line interface (2) (11), keyboard and mouse interface (12), USB interface (2) (13), IDE/ATAPI interface (2) (14), serial line interface (2) (15), linear audio R/L input interface (16), linear audio R/L output interface (17), microphone interface (18), earphone interface (19), CD audio frequency R/L input interface (20), TFT interface (21), VGA interface (22).Central processing unit (1) is selected the low-power consumption of National Semiconductor company, the SC1210 processor and the peripheral circuit of high integration for use, processor provides MMX technical support, high slow, the 2D acceleration of 16KB one-level on the sheet, support CRT and TFT while or independent operation, two EIDE interfaces, support the Ultra33 dma mode.Built-in Type II CF draw-in groove, two TTL 16550 compatible serial ports.Two-way, as to meet an EPP/FCP standard parallel interface, two USB interface.DVD decoding circuit (2) adopts EM8400 series audio frequency and video decoding chip and the peripheral circuit of Sigma Designs, energy DVD playing back, DVD Audio, SVCD, VCD1.x/2.0, the audio frequency and video program of forms such as CD-DA.Ethernet controller (3) selects for use the 10/100Mb/sEthernet controller DP83815 of National Semiconductor company and peripheral circuit to carry out pci bus control.Interface circuit (4) selects for use the PC87360 interface chip of National Semiconductor company and peripheral circuit to carry out the various interface expansion.Audio encoding and decoding circuit (5) selects for use the audio encoding and decoding chip LM4548 of National Semiconductor company and peripheral circuit to carry out the sound input and output.BIOS circuit (6) selects for use PAL/NTSC/SECAM video decoder chip SAA7114H and peripheral circuit to carry out the composite video signal input manager for the 32M storer in order to deposit BIOS program curing NTSC/PAL scrambler (7).Terminator (8) transfers pci bus in order to isa bus.
Be the embodiment of this patent below:
Central processing unit (SC1210) (1) reads the DVD-ROM CD-ROM drive program data that links to each other with IDE/ATAPI interface (14), reach DVD decoding circuit (EM8400 series) (2) by pci bus, after DVD decoding circuit (EM8400 series) is handled, pass central processing unit (SC1210) (1) again back by NTSC/PAL scrambler (SAA7114H) (7), by central processing unit (SC1210) (1) with audio frequency, vision signal is by audio encoding and decoding circuit (LM4548) (5), TFT interface (21), VGA interface (22) is play and the TFT display screen, the VGA display screen shows.
Terminator (8) transfers pci bus in order to the isa bus with BIOS circuit (6), by carrying out reading and writing data between Ethernet controller (DP83815) (3) control central processing unit (SC1210) (1), DVD decoding circuit (EM8400 series) and the BIOS circuit (6) (by terminator (8) conversion).
NTSC/PAL scrambler (SAA7114H) (7) carries out the vision signal input manager, as vision signal is the composite video input signal that composite video input interface (10) comes, and then by central processing unit (SC1210) (1) the processed video signal is exported by composite video output interface (9).
Because the input/output port of central processing unit (SC1210) (1) itself can not satisfy vehicle-mounted computer institute palpus port number, carry out the port expansion by interface circuit (PC87360) (4), expansing serial interface (2) (11), keyboard and mouse interface (12), have 4 serial line interfaces at the vehicle-mounted computer mainboard like this, these 4 serial line interfaces as required can external GPS locating device, touch-screen, device for mobile communication, infrared remote-control device etc.
Audio encoding and decoding circuit (LM4548) (5) carries out management such as sound input, output, coding, decoding, total linear audio R/L input interface (16), linear audio R/L output interface (17), microphone interface (18), earphone interface (19), CD audio frequency R/L input interface 5 interfaces such as (20) can connect equipment such as sound equipment.
Vehicle mounted computer main board develops for vehicle-mounted computer, have low in energy consumption, integrated level is high, merit Can be strong, favorable expandability, support several operation systems, the characteristics such as transplantability is good can be widely used in the worker The fields such as industry control, instrument and meter, network communication, home entertaining.
