CN103092964A - Parent-child Point of Information (POI) query method of navigation device - Google Patents

Abstract

The invention discloses a parent-child point of information (POI) query method of a navigation device. The parent-child POI query method includes the functional modules of a retrieval module, a POI pickup module, a POI detailed information query module, a parent-child POI query module, a parent-child list making module, and a POI database, wherein the retrieval module is used for providing common retrieval functions, the POI module is used for providing pickup function of POI on navigation maps, the POI detailed information query module is used for query detailed information of the POI provided by retrieved results or POI pickup module and providing the detailed information of the POI, and the parent-child list making module is used for providing associated relations. The method includes the following steps: obtaining the POI information through destinations which need to be found, querying the detailed information of the POI in the POI database, judging whether association exists in the POI or not, producing execution process of the query, finding associated POI, making a list, and providing the list. The parent-child POI query method of the navigation device has the advantages of expanding the range of the retrieved result, increasing the success rate of one-time query, further simplifying the query process, and avoiding the trouble of repeated queries.

Description

A kind of father and son POI querying method of navigator

Technical field

The present invention relates to field of navigation technology, particularly a kind of father and son POI querying method of navigator.

Background technology

POI is the abbreviation of " Point Of Interest ", translates into point of interest, is the information point of including in the navigation map data storehouse, usually comprises title, classification, positional information, address and phone etc.For POI, we can inquire about according to information such as title, classification and positions usually, and except these conventional methods, we can also inquire about POI by father and son POI.

Father and son POI refers to can exist between POI a kind of incidence relation of inherence, as: the geographic position, the locus, subordinate relation etc., for example: each company in mansion, the mansion is as father POI, and each company in the mansion is sub-POI, for having this seemingly POI of father and son's incidence relation, be called father and son POI.

In traditional navigation, POI is isolated the existence, has ignored the incidence relation between POI.And this contact between POI has been considered in the generation of father and son POI just.If effectively utilize this contact, can help the user, the POI of positioning searching, simplify and search flow process fast, reduces unnecessary operation.

Summary of the invention

The objective of the invention is to simplify search procedure in order rationally to utilize the relation of father and son POI, the spy provides a kind of father and son POI querying method of navigator.

The invention provides a kind of father and son POI querying method of navigator, it is characterized in that: the father and son POI querying method of described navigator adopts following functional module to implement:

Retrieval module provides common search function, such as passing through the querying conditions such as title, classification and positional information, completes the search function of POI, and the functions such as list demonstration of Query Result are provided.The POI pickup model is provided at the hit detect function of the POI information point on navigation map, if pick up on map successfully, and the POI point that the prompting user has picked up; POI details enquiry module, the POI for result for retrieval or POI pickup model provide carries out the inquiry of details, and the details of POI is provided; Father and son POI enquiry module is inquired about current POI and whether is had father and son POI relation, if there is the father and son POI that provides related, if there is no, and the prompting user, there is not father and son POI relation in this POI; Module is made in father and son POI list, for the POI that has father and son POI, the list of the related POI of this POI is made, and provided related relation; The POI database, in the POI query script, the navigation map data storehouse of use comprises the index data of inquiry, the essential information of POI, the incidence relation of father and son POI;

The father and son POI querying method flow process of navigator is as follows:

The application scenarios of father and son POI, at first by the destination to searching, search with search method commonly used, the search function of inquiring about by modes such as title, classification and positions is provided in navigation, perhaps obtain the position of destination by the rolling map, by the mode of picking up, obtain the information of POI;

After determining a POI through the mode of retrieving or pick up, call POI details enquiry module, in the POI database, inquire about the details of POI;

When the details of inquiry POI, judge whether this POI is father and son POI, namely whether has related POI, if exist, there is attribute in father and son POI, be set to effectively, otherwise it is invalid to be set to; If it is invalid value that there is attribute in father and son POI, the details of POI are provided; If it is effective value that there is attribute in father and son POI, whether the inquiry user needs further to check the information of the related POI of this father and son POI, if need to obtain the information of the related POI of this father and son POI, call father and son POI enquiry module, inquire about the incidence relation of this father and son POI, the execution flow process of generated query;

According to the querying flow that father and son POI generates, search the related POI of this father and son POI, according to lookup result, make the list of related POI; The POI of association according to display format, is provided; The related POI itself that provides remains father and son POI, therefore still searches by this POI the POI that is associated when checking related POI.

Advantage of the present invention:

The father and son POI querying method of navigator of the present invention, by the father and son POI in the primary retrieval object information, search again the POI that is associated, to a certain extent, enlarged the scope of result for retrieval, improve the success ratio of one query, further simplified querying flow, avoided the repeatedly puzzlement of inquiry.
