An electronic map communication device and use based on GPS global position system

Abstract

An electronic map communication device based on GPS Global Position System, which includes: controlling means, a palmtop computer, GPS module, GSM module; whichin the Palmtop computer connects to the GPS module, and initializes the GPS, the palmtop computer is provided with an electronic map and receives the data sent from the GPS module; The palmtop computer connects to the GSM module, initializes the GSM module, the palmtop computer shows the simulation keyboard and dials to put through the radio communication network by the simulation keyboard; The palmtop computer displays call information and the simulation keyboard and chooses to put through the radio communication network by the simulation keyboard; the control device connects to the palmtop computer, outputs the control signals to the palmtop computer and receives the signals from the palmtop compter; the control device connects to the GPS module, outputs control signal to the GPS module and receives the signals that were sent from the GPS module; the control device connects to the GSM module and outputs control signals to the GSM module and receives the signals that were sent from GSM module.

Description

technical field [0001] The invention relates to the field of electric communication, in particular to an electronic map communication device based on the GPS global positioning system and its application. Background technique [0002] With the rapid development of communication technology, a system that combines GPS global positioning system and electronic map has appeared, and its purpose is to provide users with satellite navigation. At present, most of GPS is realized by hardware, and its expensive price has caused difficulties in application promotion. However, most of the current electronic maps are re-digitized maps that have been published, and their products are one-dimensional. Therefore, the accuracy of this electronic map is not enough. When accurate navigation is required, this electronic map cannot meet the requirements at all. Although foreign GPS products with expandable map modules have been used, their high prices and the particularity of the country's map ...
