Deficiency in view of above-mentioned technology, one of purpose of the present invention provides a kind of querying method, this method is formed the index key that this waits to look into the destination with the initial of the phonetic of each Chinese character of destination title, and, take the search algorithm of front end unanimity, when importing above-mentioned initial one by one, in display unit, can demonstrate key word and the identical or approximate place name of input alphabet.
Two of purpose of the present invention provides a kind of querying method, and input waits to look into the initial of phonetic of each Chinese character of the abbreviation of destination title, and the place with identical abbreviation all is retrieved out, and demonstrates the full name of its title.
For this reason, the present invention takes to form the method that this index key of waiting to look into the destination is inquired about with the initial of the phonetic of each Chinese character of destination title, thereby has shortened the time of input inquiry information.And, also taked the querying method of front end unanimity.Like this, when the user in input time, the record that the letter of key word front is identical with user's input alphabet can both be retrieved out according to this, the user can select in these records, the initial that also can continue to import the phonetic of back Chinese character is retrieved until information needed with the indentation range of choice, be presented at top record position, can also be according to the mistake in the timely more positive input of Query Result.Because Query Result has just shown in input, slightly variant information can both be found by the user in query script so those are because the appellation custom is different.
In addition, consider that there is more common abbreviation some destinations, and these are called for short and destination full name differences is bigger, so the present invention also takes another querying method, i.e. input waits to look into the initial of phonetic of each Chinese character of the abbreviation of destination title, the place that has identical abbreviation in the geographic information database is all retrieved, and demonstrate the full name of its title.The user just can search out the information that oneself needs in these result for retrieval.Also can find required information when like this, the user imports the first letter of pinyin of each Chinese character of abbreviation of these destinations.
Below in conjunction with the invention example the present invention is elaborated.
Can realize these purposes with the geographic information database inquiry unit by a kind of vehicle, this geographical information query device comprises CPU (central processing unit), this CPU (central processing unit) is according to the information that obtains from entry terminal, according to the program that is solidificated among the ROM (read-only reservoir), inquire required destination title and latitude and longitude information thereof from the geographic information database that is arranged in the geography information storage unit, and the control display unit shows the destination title that inquires.This geographic information database inquiry unit also comprises: operation panel unit is used for input inquiry information as entry terminal and reaches at query script as selection tool; Display unit is used to receive video data and the video data that receives is presented at screen; The geography information storage unit is used to store data such as geographic information database.
At first, the central processing unit controls display unit demonstrates the initialization interface, and the content at interface mainly is divided into three parts: viewing area, phonetic alphabet button area and control knob zone.It on the phonetic alphabet button area button of 26 phonetic alphabet.Then, the user utilizes operation panel unit to import the initial of phonetic of the destination title of desire inquiry, the i.e. simplicity of destination title according to the order of sequence.The central processing unit controls display unit is presented at user's input in the viewing area, and according to user's input in user's input, in the geographic information database of geography information storage unit storage, inquire about synchronously, and Query Result is outputed in the viewing area of display unit.
Further specify the present invention referring now to accompanying drawing, these accompanying drawings are:
Fig. 1 is suitable for the block scheme of vehicle of the present invention with the geographic information database inquiry unit;
Fig. 2 is a synoptic diagram, and the interface that the present invention who is presented on the display unit is used to inquire about geographic information database is shown;
Fig. 3 is a synoptic diagram, and the flow process that the present invention is used for a kind of inquiry mode of geographic information database inquiry is shown.
Fig. 1 illustrates and is suitable for the block scheme of vehicle of the present invention with the geographic information database inquiry unit.
As shown in Figure 1, inquiry unit comprises geography information storage unit 10 at least, and data such as geographic information database are stored in this unit.Under the control of CPU (central processing unit) 12, geography information storage unit 10 also takes out data such as geography information and the information of taking out is delivered to CPU (central processing unit) 12.Inquiry unit also comprises operation panel unit 11, and this unit has many function keys, can the valid function inquiry unit.Select suitable key by operation panel unit 11, just between user and inquiry unit, form operation interface.Display unit 13 also is connected in CPU (central processing unit) 12, so that show the various situations that the geography information that reads from geography information storage unit 10 and action queries device take place under CPU (central processing unit) 12 control.
CPU (central processing unit) 12 comprises ROM (read-only reservoir) that stores the program that control inquiry unit whole operation is arranged and the RAM (random access reservoir) that is used for temporarily storing deal with data during the action queries device.CPU (central processing unit) 12 with this structure can be inquired about in the geographic information database stored in geography information storage unit 10 of information according to input from operation panel unit 11.Then, CPU (central processing unit) 12 is delivered to display unit 13 with retrieved message, and this unit by CPU (central processing unit) 12 controls, shows retrieved message again.
