Electronic peripheral card of global satellite location system which can be dynamically plugged or drawn to obtain navigation information

Abstract

The present invention relates to an electronic peripheral card of global satellite location system for dynamically inserting-extracting navigation information. It has a multiple interface controller, a dynamic inserting-extracting card interface in which a storage card with stored map data can be dynamically inserted, a global satellite location system module and a main machine interface. When a storage card is inserted into the dynamic inserting-extracting card interface, said dynamic inserting-extracting card interface can notify that to said multiple interface controller, and further utilizes the main machine interface to notifying main machine to read the map coordinate data of said storage card to display the correspondent map; after the location coordinate is calculated by said global satellite location system module.

Description

Technical field [0001] The invention relates to a multi-interface electronic peripheral card, in particular to a global satellite positioning system electronic peripheral card suitable for portable devices that can dynamically plug navigation information. Background technique [0002] With the advancement of satellite communication technology, the use of global satellite positioning systems has gradually become widespread, and due to the miniaturization of electronic devices, the terminal equipment of the global satellite positioning system can be implemented in, for example, personal digital assistants (PDAs). ) Portable electronic device, the user only needs to carry the personal digital assistant device to have the function of global satellite positioning. [0003] In the realization of the global satellite function with the aforementioned personal digital assistant device, the current practice requires first inserting a memory card storing map data of a certain area into the ...

[0004] However, when the user arrives in a new area and needs to change the map data, the GPS module card must be pulled out, and a memory card storing the map data of the area must be inserted into the PCMCIA / CF of the personal digital assistant device. slot, and load the new map data into the memory of the personal digital assistant device again, after that, pull out the memory card, and then insert the GPS module card into the PCMCIA / CF slot of the personal digital assistant device, so The process is obviously extremely cumbersome and inconvenient to use

[0005] In order to improve the aforementioned shortcomings, a direct method is to make the storage module and the GPS module on a multifunctional electronic peripheral card, and the memory module therein stores the map data of a certain area. Therefore, as long as the Insert this multifunctional electronic peripheral card into the PCMCIA / CF slot of the personal digital assistant device, and then the map data can be loaded into the memory of the personal digital assistant device, and the coordinate position of the user can be located by receiving the signal of satellite positioning, however , when the user arrives in a new area and needs to change the map data, the multi-function electronic peripheral card must still be pulled out, and another multi-functional electronic peripheral card with a GPS module and a storage module storing the map data of the area must be replaced. The functional electronic peripheral card is inserted into the PCMCIA / CF slot of the personal digital assistant device, and the new map data is loaded into the memory of the personal digital assistant device again, which will cause interruption of GPS execution and lead to poor performance
