Information coupling system, map information supply apparatus for area navigation and area navigation apparatus

Abstract

The invention relates to an information coupling system for regional navigation, a cartographic information supply device and a regional navigation device. Firstly, a regional cartographic information is written to a storage module of the cartographic information supply device by a write module, then the cartographic information supply device transfers the regional cartographic information to the regional navigation device in a wired or wireless manner, and a user can know the feature information of each special position point through the operation of special position points on the map, or the regional navigation device can generate corresponding regional trip path according to the requirement of the user to facilitating the trip of the user. Meanwhile, the cartographic information supply device and the regional navigation device have low cost, thus greatly lowering the navigation cost to provide benefit for more common people and enable the people to fully know the various feature information in a certain region.

Description

technical field [0001] The invention relates to an information coupling system for regional navigation, in particular to an information system coupled by a map information supply device and a regional navigation device. Background technique [0002] At present, GPS-based satellite positioning and navigation systems, such as car navigation systems and smart handheld device navigation systems, can provide convenient and intuitive real-time location navigation with regional or city maps. However, GPS-based navigation systems have higher requirements for terminal devices. Specifically, the following characteristics are shown: 1. The processor capacity requirements of the terminal are relatively high (mostly require support for open embedded OS, such as WINCE, LINUX, Symbian, PALM, etc.); High power consumption, continuous work during navigation); 3. High terminal cost (mostly high-end smart phone architecture, which requires a built-in or external GPS module); 4. Large storage i...

AI Technical Summary

Problems solved by technology

In addition, GPS navigation is also difficult to solve precise navigation in local areas, let alone the location and information navigation inside the building, and these locations and information navigation have great practical value for the public

[0003] However, the existing position positioning and information navigation based on wireless communication base stations are mainly for mobile phone users. Although this technology has low requirements on the overall performance of mobile terminals and is easy to implement, this information navigation is mainly described in text. It is not intuitive enough, and it is difficult to couple the information description with the specific geographical location. At the same time, it is difficult to guarantee the accuracy of the expression of the geographical location by text information, and the amount of information contained is also limited.
