> Along with the people living standard
enhancement, the private upscale vehicle quantity is more and more
big, comes from to the national correlation statistics department's
data display that, Recent years, the our country domestic new
vehicle produced the sales volume approximately is 600,000, this
numeral in 2005 achieved 1.1 million, so far, the domestic private
vehicle quantity conservative estimate also had 5.3 million,
definitely was allowed to break through 10 million to 2010, in these
vehicles 1,/10 will install the automobile from the navigation
product, therefore inserted the type geography information to have and
its the broad application prospect. The automobile is smoothly
arrives the destination from the navigation for the driver under not
the familiar environment, cannot become lost, saves the time, enhances
the efficiency, therefore more and more receives welcome gradually to
walk into people's life. Below the automobile mainly has the
function from the navigation: 1. intelligent navigation function
2. The entire journey voice prompt 3. drifts off course the
error correction function 4. The electronic map function 5.
wireless accesses the net function 6. The entertainment function
7. travelling schedules records and return put the function [ System principle > The satellite positioning automobile integrated
the satellite positioning technology from the navigation aid (GPS),
the geography information management (GIS) and the Internet
technology, take the electronic map as the foundation, through the GPS
receive satellite signal, can complete the intelligent way plan, the
entire journey voice prompt, electronic function and so on map
browsing, satellite positioning navigation, moreover also has on the
palm computer all functions, for example: Sets at 56k MODEM
through in to access the net the browsing, receives and dispatches
function and so on E-mall, language processing, electronic forms, MP3,
game. Not only enables the people smoothly to arrive the
destination under the strange environment, moreover can cause the
driver to access the net on the vehicle understood as necessary
information and so on when person may carry on the entertainment.
[ System diagram > Automobile from navigation function formidable,
not only must be able to demonstrate the map speed is quick, can
enlarge to the map reduces responds quickly, moreover must have the
massive data storage space to carry on the track data to save in order
to returns puts as well as saves the massive positional information.
The common monolithic integrated circuit has not been able to
complete the so high request, needs the rank high to insert the type
single board computer sbc in addition to take the hardware platform. The automobile mainly has following several requests from
the navigation to the hardware platform: 1st, formidable CPU processing operation ability
2nd, formidable data storage ability
3rd, formidable demonstration ability
4th, can provide many strings mouth and a AUDIO mouth,
can support TFT real color LCD
5th, the hardware single trigger volume is small
6th, bigger compatibility and extension
[ System appraisal > 1. has the high performance, the low power loss,
light-sized, PC compatible, is completely easy to promote and so on
the characteristic
2. structures nimble, the expansion are easy
3. installed the way fully to consider the anti-
vibration adverse circumstance application request
[ System disposition > Motherboard: ETX - 1541CLDNA (GX233CPU)
Memory: 32M
DOM: 64M ETX is the Embedded Technology Extended
abbreviation, is one kind inserts the type PC standard. ETX mainly faces the special purpose computer system board
the designer, its core idea is "equally designs the PC likely chip the
customer in the goal application system". Therefore designed the
personnel definitely to be allowed to regard as the ETX module is
integrated CPU, PCI main line, ISA main line as well as standard PC/IO
function special chip. The ETX series product must unify the
user the PCB foundation plate to use together. ETX structure characteristic: ETX has the high
performance, low power loss, light-sized, completely PC compatible, is
easy to promote and so on the characteristic. It installed the
way fully to consider the anti- vibration adverse circumstance
application request. Is one kind suits the labor to control the
profession request the industry motherboard. ETX took one kind
inserts the type industry motherboard standard, the most prominent
performance for the structure nimble, the expansion is easy, the size
is exquisite and so on, inserts the type with the present to be
possible to cut out the thought to tally, conforms to the industrial
development tendency. Mainly is accelerates the ODM customer
product design cycle in the application aspect.
