It should be said that there are different between the Car PC and the common desktop, which is dependent up on the function of the car pc and the car environment.
Functionally, I think the main board computer has the following functions:
1, audio and video entertainment. Can play MP3, DVDRIP movies, audio and video files, you can stop the course of such person or vehicle to the driver, passengers boredom
entertainment purposes, of course, traffic can only listen to the voice of the driver.
2, GPS navigation. A computer, the function is very powerful, just a little investment, plus take a GPS receiver, with some software to be used for navigation, on the one hand
is a very useful feature, but it is also to their own car increased the number of high-tech car charm.
3, when they go out as the vehicle computer, we can do some simple accounting, diary, digital photos, and more general computer down often do.
Loading restrictions on car computer:
1 car space is limited, especially as we pony car that A0-class car, space is limited, so car computer must be as small as possible;
2, power supply, car power supply is only 12V, the battery capacity is not large, as we pony only 45AH, so the car computer power must be strictly controlled, otherwise, on the
one hand the current is too large to bring wiring, heating difficulties On the one hand, turn off the computer after the life will be greatly reduced. Be careful not to start up
when the truck!
3, the installation, should be minimal damage to the original car structure, easy operation, would not block the original vehicle equipment, switches, etc., but also note that
absolutely can not affect safety. For this we pony car, but also a big test.
Integrated the above factors, I made the following selection of car computer:
1, the board: INTEL integrated motherboard, 845GV chipset, integrated sound card was, and CPU, the most important thing is small enough: 17X19CM, there is a simple version
because of the integrity of the PM 1G processor, performance can meet the requirements of power consumption is very low.
2, Memory: 512M DDR 400 ------ memory is still relatively cheap, directly on the 512M. Large memory systems can reduce the time to read the hard disk, on the one hand can play a
role in protecting the hard disk, but it is also able to reduce power consumption.
3, the hard disk: Samsung 40G notebook drives notebook hard drives ------- must, on the one hand size, power consumption, shock resistance are better out on the one hand, after
all, is used in the car ah. Notebook hard drive big or expensive, first playing the whole 40. MP3 release point of what should be sufficient.
4, Power supply: integrated ITPS Power ----- 12V input, ATX output to the ignition key with the location, according to changes in vehicle automatically switches the computer,
just like the original car stereo look easy.
5, GPS Receiver: HOLUX GR213 GPS MOUSE ---- will not be the highest performance GPS MOUSE is it?
6, Display: 7 inch LCD display with touch measure function, daily use of just "pointing" it you will do it!
7, Chassis: Other people help me DIY small chassis, the size of about 22X24X6CM. It can be placed under auxiliary seat.
