Description
Technical field
A kind of Vehicle meter display system is the utility model is related to, more particularly, to a kind of auto meter of two-ways cpu
Display system.
Background technology
Present automobile function, which becomes increasingly complex, needs the information that shows also more and more, and traditional automobile instrument panel is shown
Content is fixed and single, and the information of display is unable to spread conversion.And with the increase of display information, instrument board needs
Increase area simultaneously sets up instrument, and this is in limited interior space and its limited, and causes index dial structure complexity to increase
Add, wiring is more more complicated.Moreover, even if being designed to more complicated structure, can not meet in display effect and complexity
Hold the demand of display etc..Existing Vehicle meter display system uses single CPU, operation real time operating system come obtain compared with
Good display effect and realization shows complex content.
But because the display of instrumented data requires high toggle speed and the response speed being exceedingly fast to ensure security.
In addition, when realizing the functions such as the more complicated such as navigation of completion, media play, networking using single cpu system can be caused very multiple
It is miscellaneous, strong influence toggle speed and response speed, cause security to reduce, so as to be difficult to meet that what automobile instrument show wants
Ask.So even if automobile has Vehicle meter display system now, while also need to additionally to increase a central control system and led to handle
The tasks such as boat, multimedia.Such system was both uneconomical, also the confined spaces for occupying in-car more.
Utility model content
To solve the above problems, the utility model uses dual-cpu structure, CPU is divided the work, improves CPU processing speed
Degree.Make system that there is very high toggle speed and response speed, substantially increase the security of system.
Above-mentioned purpose is accomplished by the following way in the utility model, there is provided a kind of auto meter display system of two-ways cpu
System, it is characterised in that the automobile-used display system includes：Screen, the first control module and the second control module；The screen tool
There is screen interface, the screen connects first control module, obtains display data and show letter by the screen interface
Breath；First control module includes the first CPU and microcontroller, and the first CPU connections microcontroller simultaneously receives institute
State the information for coming from vehicle of microcontroller collection；The microcontroller connects vehicle data line, and from the vehicle data
Line transceiving data；And second control module includes the 2nd CPU and GPS module, the 2nd CPU passes through data wire and institute
GPS module is stated to connect and communicate；Wherein, the 2nd CPU connects the first CPU by data wire, and will can need aobvious
The Content Transformation shown is sent to the first CPU into media data by data wire；The first CPU connections screen is simultaneously
The display data is provided for the screen.
Second control module also includes radio, and the radio is connected with the 2nd CPU.
Second control module also includes audio frequency apparatus, and the audio frequency apparatus is connected with the 2nd CPU.
Second control module also includes bluetooth module, and the bluetooth module is connected with the 2nd CPU.
Second control module also includes 4G modules, and the 4G modules are connected with the 2nd CPU.
Vehicle meter display system of the present utility model changes the side of single CPU operations of traditional Vehicle meter display system
Formula, the very high instrument display content of security and requirement of real-time is responsible for specially using the first CPU, direct control instrument is shown
Screen, while additionally one the 2nd CPU of increase is responsible for specially handling the complicated but not high task of security, for example navigate, network,
The tasks such as multimedia, bluetooth.After the 2nd newly-increased CPU has handled corresponding task, it will need to show by high speed data lines
Content be transmitted to the first CPU, and the first CPU only needs a simple division region on screen to show what is transmitted from the 2nd CPU
Content, such first CPU only increase the task that the data received are shown, can be to allow instrument board to be shown in instrument
Outside content, the very more function of superposition.Instrument board and navigation, the work(of entertainment systems have been provided simultaneously with equivalent to single instrument board is allowed
Energy.Because two CPU share a screen, there is more preferable Consumer's Experience while reducing cost, less safe complexity is appointed
Business is due to operating on the 2nd CPU, even if the 2nd CPU there is a problem, does not influence the instrument of the CPU controls of high security completely
The normal function of display system.
Brief description of the drawings
Fig. 1 is the module diagram according to the Vehicle meter display system of an embodiment of the present utility model.
Wherein accompanying drawing is that content of the present utility model is schematically illustrated, not using content shown in the drawings to this
The content of utility model is specifically limited.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment.
Fig. 1 is a kind of module diagram of Vehicle meter display system, including CPU 1, CPU 2 and connection CPU 1
And CPU 2 tells data wire 3.CPU 1 runs the real time operating system of high security, is mainly used to drive screen 5 to show,
The typesetting and switching of display content are carried out, and display effect renders, receive that microcontroller (MCU) 4 gathered comes from
The information of automobile, receive to come from the data of data that CPU 2 needs show and control correlation from high speed data lines 3 simultaneously
Subregion is divided on screen to show.The microcontroller 4 being connected with CPU 1, from transceiving data on car data line.Screen
Curtain 5 obtains the data of display from CPU 1 by screen interface 11 and shown.
CPU 2 runs the complex operations system of common security, processing navigation, radio, audio, bluetooth, communication etc. times
Business, and the Content Transformation for needing to show is sent to CPU 1 into media data by high speed data lines, while send in the lump a small amount of
Control category information.
GPS module 6, radio 7, audio frequency apparatus 10, bluetooth 8,4G modules 9 are communicated by respective data wire and CPU 2,
