Detailed description of the invention
The present invention is described in detail with reference to the accompanying drawings and detailed description:
Fig. 1 is a kind of flow chart of the multilingual dynamic display method for vehicle-mounted digital instrument of the present invention；
Fig. 2 is a kind of structural schematic diagram of the multilingual dynamic display system for vehicle-mounted digital instrument of the present invention.
Specific embodiment
As shown in Figure 1, a kind of multilingual dynamic display method for vehicle-mounted digital instrument, comprising:
S101, information prestore: being pressed by display information of the LZW compression algorithm to the multilingual of vehicle-mounted digital instrument
Code is reduced the staff, and is pre-stored in code database.
Wherein, the present invention supports 11 kinds of language, and display information refers to automobile information, warning information etc..
LZW (Lempel-Ziv-Welch) compression algorithm, is called " string list compression algorithm ", exactly by establishing a character
String list indicates longer character string with shorter code to realize compression.
If desired vehicle-mounted digital instrument support 11 kinds of language Dynamically Announce, and the vehicle-mounted digital instrument have 200 not
Same display information, then 11 kinds of language just have 2200 information to need to store, the majority of some of same meanings of phase cognation
The character of display information be it is identical, will cause the waste of memory space, and hardware store if whole code storages
Condition is extremely difficult to demand, and uses LZW compression algorithm, if the display information character for different language identical meanings is phase
With situation, then only a kind of language is encoded, and for show information character it is not exactly the same in the case of, then
It will show that the character repeated in information only carries out first encoding in this, the character occurred for the first time then recompiles supplement
Into code database, therefore the different display information of meaning is saved as the encoded information of corresponding different Information IDs, meaning by the present invention respectively
The identical display information of identical and character saves as an encoded information, and meaning is identical and the different display information of character is divided
The different coding information of corresponding identical information ID is not saved as, and each encoded information corresponds to corresponding Language ID, referring to
Table 1 can find corresponding encoded information by Information ID and Language ID from code database.
Table 1
In table 1, ABC and AEFG are the different display information of meaning, then the two is saved as to corresponding different information respectively
ID11,12 encoded information, and character identical for meaning is the display information of ABC, then these display information save
For an encoded information (Information ID 11), ABC and ABD are that meaning is identical and the different display information of character, then by the two
The different coding information of corresponding identical information ID11 is saved as respectively, and every encoded information corresponds to corresponding language in table 1
ID。
The present embodiment can realize multilingual Dynamically Announce in segment display, and in order to improve response speed, needing will be more
The letter and the corresponding segment encode of symbol of the display information of kind language are pre-stored in segment encode library.
Preferably, above-mentioned code database and segment encode library prestored information in a tabular form.
S102, encoded information are searched: the current Language ID of vehicle-mounted digital instrument is read, it is aobvious by the Language ID and request
The Information ID for the display information shown finds corresponding encoded information from code database.
S103, decompression: being decoded encoded information by LZW decoding algorithm, obtains showing information accordingly.
S104, information are shown: decoded display information is shown on a display screen, further comprising:
A, corresponding default display format is selected according to Language ID, display position, Right Aligns, a left side such as on a display screen is right
It is neat or placed in the middle etc..
B, corresponding segment encode collection is successively found by the character of display information from segment encode library.
C, above-mentioned display format is pressed, shows above-mentioned segment encode collection on a display screen.
By taking display " DANGER " warning information as an example.After vehicle body detects dangerous information, corresponding warning information can be sent
ID gives vehicle-mounted digital instrument, and vehicle-mounted digital instrument reads current language setting and obtains current Language ID, and passes through the language
ID and warning information ID, finds corresponding encoded information from code database, is then believed by LZW decoding algorithm the coding
Breath is decoded, and obtains showing information accordingly, and then select display format in the bottom left of display screen according to Language ID
It has been shown that, and from segment encode library by the character of above-mentioned display information successively find corresponding segment encode collection (0x211F, 0x0C6F,
0x40EC, 0x087B, 0x0C73,0x4C67), above-mentioned display format is finally pressed, above-mentioned segment encode collection is shown on a display screen, makes to show
Display screen shows " DANGER " on the left of bottom end.
The present invention supports the Dynamically Announce of 11 kinds of language, is believed by LZW compression algorithm the display that 11 kinds of language uses arrive
Breath carries out coding compression and is stored in code database, meets hardware store condition, so that the driver of different demands be allow to appoint
The hobby language of meaning selection oneself, also eliminates automobile on the other hand and reconfigures output language when country variant is produced and dispatched from the factory
The work of speech, is greatly saved production cost.
