And the corresponding dot matrix of the region-position code is obtained according to region-position code dot array data storehouse, and the dot array data is sent to into display device is shown
Show.
Especially, the packet of the way point information is sent to control display unit by HB6096 buses by navigation component, and logical
Cross the Chinese information universal standard communication protocol set up to be communicated, the Chinese information universal standard communication protocol is based on HB6096
Bus protocol, state matrix and parity check bit are consistent with which, and wherein, each packet has 4 32 data, the
Most least-significant byte index value in one 32 data is that 0X77 representative informations are Chinese character 1, minimum 8 in second 32 data
It is Chinese character 2 that position index value is 0X78 representative informations, and the most least-significant byte index value in the 3rd 32 data is that 0X79 represents letter
Cease for Chinese character 3, it is Chinese character 4 that the most least-significant byte index value in the 4th 32 data is 0X78 representative informations；Each 32 digit
High 16 according in are used for transmitting Hanzi section-position code, and most most-significant byte is with binary-coded decimal format transmission area code, secondary most-significant byte with binary-coded decimal
Format transmission bit code；The 16th data in each 32 data represent the validity of Hanzi section-position code, 1 effectively, 0 invalid.
More specifically embodiment：
According to way point database store structure inside step one inertial navigation system, the navigation of project way point database purchase is set up
Parameter information；With 01 way point in No. 2 course lines, as a example by way point Chinese Xi'an:Way point title west is obtained by software
Pacify corresponding Hanzi section-position code and be respectively 4687 and 1618, region-position code data message is pressed into way point structure information storage form,
See accompanying drawing 2, stored.
Uc_wp_fp_no=2；/ * course lines number be 2*/
Ui_wp_no=01；/ * air routes period be 1*/
Uc_wp_name [1] [0]=46；1 area's code of/* way point titles word, West code 46.*/

The control instruction of No. 1 point in No. 2 course lines of inquiry of step 2 receive user, analysis instruction are intended to, and are adjusted according to command request
The Chinese information stored in degree inquiry air route point data base.First, No. 2 course data storage startings are reduced to according to route information
Address 0X8,010 0000；Secondly, according to air route period, get and change region way point skew 0X0,000 0000；Final should
Way point information starting 0X8010 00,00+,0X0,000 0000, obtain way point information.
Step 4 by Chinese region-position code information " Xi'an ", according to Chinese information universal standard communications protocol format, can use by generation
In the bus data of HB6096 bus transfers, the transmission of bus format Chinese data is completed, Fig. 3 is seen.
According to 4 32 BITBUS network data words of communications protocol generation transmission " Xi'an " it is：
0X2E57 0677；
0X1012 0678；
0XFFFF 0679；
0XFFFF 067A。
Step 5 control display unit receives the Chinese information of bus transfer, to the total of Chinese information universal standard communications protocol format
, according to being parsed, the word that fetches data is high 16 for line number, and most most-significant byte is area's code, and secondary most-significant byte is bit code；Generate Chinese information correspondence
Hanzi section-position code 4687 and 1618.
Step 6 is by conversion map method, area code code1, bit code code1, Chinese character digit hz_no in mark character library, the Chinese
Starting position coordinates Len of the word in font file, Chinese character dot matrix buffering area hz_buff [32]；Obtain Chinese character point methods as follows：
Hz_no=((code1＆0x07f) * 94)+(code2＆0x07f)；
Len=hz_no*32L；
32 byte dot array datas are continuously read in hz_buff [32] from standard dot matrix word library HZK16 file Len positions, that is, is obtained
The dot array data of the Chinese character.Chinese information " Xi'an " corresponding character lattice information is obtained according to the method, to Chinese character dot matrix according to
According to display algorithm, carry out picture element scan and show to form Chinese Graphic.
It is as follows that Chinese character dot matrix presses picture element scan display methods；
By more than, operation realizes that user checks process Chinese Information application problem to inertial navigation system air route, improves navigation letter
The display capabilities of breath, increased the convenience of user's manipulation.
