Embodiment 1

[0021] This embodiment provides a method for incremental update of embedded POI data that supports incremental update, characterized in that: the incremental update process is to add differential data to the original data, so that the original data is upgraded to the latest data, Satisfy reversibility; a compiling module is added to the software to realize incremental update, the data in the data storage area stores the interest point information of the basic version Ver1, the differential data storage module stores the differential data, and the data compiling module is responsible for converting the information in the differential data module The data is updated to the data storage area;

[0022] The implementation method of the data compilation module is as follows:

[0023] Traversing the records, traversing each data record in the differential data between the new data and the original data, and performing a differential search on it; searching for the corresponding recor...

Abstract

The invention discloses an embedded POI (Point of Interest) data increment updating method supporting increment updating. The method is characterized in that the increment updating method comprises the steps that differential data is added to the original data to allow the original data to be upgraded to the latest data and satisfy the reversibility; a compilation module is added to software to achieve increment updating; data in a data storage area stores POI information of a basic version Ver1; the differential data is stored in a differential data storage module; and the data compilation module is responsible for updating the data in the differential data module to the data storage area; all data records in the new data and the differential data of the original data are traversed and subjected to differential search; the POI information in the differential data is differentiated and compiled to the original data; and the compiled block data is inserted into the original data. The method has the advantages that navigation and map software achieves automatic increment updating, and the convenience for a user to upgrade the POI data is improved greatly.

Description

technical field [0001] The invention relates to the field of navigation systems, in particular to an incremental update method for embedded POI data supporting incremental update. Background technique [0002] At present, the embedded navigation and map product data upgrade methods on the market are relatively simple, and the data update is basically achieved by replacing the overall data. Due to the relatively large POI data, this method cannot be downloaded and upgraded through the mobile network. In the past, the update method of the car machine was to go to the 4S shop to find professionals to help upgrade, which brought a lot of inconvenience to the user to upgrade the data. This patent is to design a solution that can be automatically updated, which greatly simplifies the complexity of updating data for users. [0003] Terminology: Navigation system: The full name is "car navigation system", which is the product of the close combination of embedded hardware, GPS, geog...
