Abstract

The invention relates to a navigating device used in region navigation, which comprises a processing module for controlling the working state of the navigating device and processing data, a user controller for receiving the control information sent from user, a navigation information output portion for outputting navigation information to user, a power supply for powering each element of the navigating device, a memory unit for storing an electric map, and a wireless signal receiving / emitting module for transmitting data with external device. the user controller receives an operation command indicating destination, the wireless signal receiving / emitting module receives a data pack sent from an external device nearest with the navigating device and obtains the present position of user via the data pack, the processing module according to the position of user, the destination, and the electric map obtains a navigation path, as the navigation information to be output to the navigation information output portion to be played, thereby realizing region navigation.

Description

【Technical field】 [0001] The present invention relates to a navigation device for small-area navigation, in particular to a data transmission using a wireless signal transceiver module and a landmark indicating device set at a fixed position to locate the user's location, and generate a navigation device based on the user's location, destination, and electronic map. The navigation path, and then obtain the comparison between the user's orientation and the navigation path according to the direction acquisition module, thereby generating navigation information indicating the direction of the user's progress, and realizing a navigation device for locating and navigating within a certain range. 【Background technique】 [0002] The current positioning and navigation technology generally adopts the Global Positioning System (GPS, Global Positioning System), which is a global positioning, navigation and timing system composed of 24 satellites launched by the US Department of Defense....
