Network, intelligentized instrument, its function are more powerful, and display content is more enriched, and wire harness link is simpler.
The function of automobile instrument is exactly to obtain the data needed and shown using suitable mode.Instrument amount in the past
Display and about 40 warning monitoring functions.Different information is by different acquisition modes and display mode, and new-type instrument is believed at present
Breath acquisition modes mainly have three kinds：Transmitted by Vehicle Body Bus；Sampled and converted by A/D；Changed by I/O state and obtained.And set
Meter is a kind of to be used to point out the LCD liquid crystal display screen of vehicular meter information to be necessary.
Utility model content
The purpose of this utility model is that providing a kind of LCD liquid crystal display screen for being used to point out vehicular meter information controls dress
Put.
In order to achieve the above object, the technical solution adopted in the utility model is as follows：
LCD liquid crystal display screen control device, including LCD liquid crystal display screen, LCD display control system, SDRAM display datas
Memory, automotive electronics signal acquisition module, the LCD liquid crystal display screen, SDRAM display data memories and automotive electronics letter
Number acquisition module is connected with LCD display control system.
Further, the LCD display control system is also connected with the first to the 3rd alarm display apparatus, first report
Alert display device is arranged at the passenger side bin location, and second alarm display apparatus and the 3rd alarm display apparatus distinguish heel row two
In individual passenger cabin.
Further, second alarm display apparatus and the 3rd alarm display apparatus are arranged on front-row seats back.
Further, first alarm display apparatus is arranged on the front panel of the passenger side storehouse.
Compared with prior art, the utility model has the advantage of：The utility model when in use, can pass through programmable control
Platform processed, freely shows relevant figure and text information etc. on LCD liquid crystal displays.It is real using Low power CPLD device drive LCD
Intelligent self-inspection is proceeded by after having showed the intelligent self-inspection and on-line monitoring fault alarm warning of system, system energization, is led to
The LCD for crossing instrument shows in the running status of body control system, car running process that system can be monitored automatically, go out item
During failure, trouble point and warning of alarming are shown by LCD.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work

The utility model is served as theme with LCD liquid crystal display systems controllers, and the chip of the LCD controller of use is
SED1520, mainly realizes Chinese display, roll screen and moves left and right function.
As shown in fig.2, LCD liquid crystal display screen be the video interface by formulation to MCU module, entered by MCU module
The corresponding computing (this computing belongs to prior art) of row, realizes the display information to be seen of various drivers, such as vehicle body failure
Information, symbol, word, language, multi-faceted prompting and warning.
LCD display control system is also connected with the first to the 3rd alarm display apparatus (1-3), the first alarm display apparatus 1
At the position of the passenger side storehouse 4, the second alarm display apparatus 2 and the 3rd alarm display apparatus 3 difference two passenger cabins 5 of heel row
In.Facilitate vehicle problematic when travelling, vehicle is all to be seen per capita, can effectively prevent the behaviors such as driver's hypervelocity.
It is preferred that, the second alarm display apparatus 2 and the 3rd alarm display apparatus 3 are arranged on the back of front-row seats 6.First report
Alert display device 1 is arranged on the front panel 7 in the passenger side storehouse 4.Each passenger can easily monitor the feelings of vehicle safe driving
Condition.
The utility model when in use, can freely show relevant figure by PLC technology platform on LCD liquid crystal displays
With text information etc..Using Low power CPLD device drive LCD, intelligent self-inspection and the on-line monitoring failure report of system are realized
Intelligent self-inspection is proceeded by after warning, system energization, the operation shape of body control system is shown by the LCD of instrument
In state, car running process, system can be monitored automatically, when haveing failure, passed through LCD and shown trouble point and warning of alarming.
