Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] figure 1 Among them, the navigation device of the present invention comprises GPS antenna (1), differential GPS receiver (2), processor (3), memory (4), input device (5), these six parts of output device (6) composition. In a scenic spot with a large range, the positioning accuracy of GPS can reach the meter level, so in this case, the better choice of the differential GPS receiver (2) is the pseudo-range differential GPS receiver; in the exhibition hall with small space , GPS positioning needs higher precision, so the better choice of GPS receiver (2) in this case is carrier phase difference GPS receiver.

[0019] figure 2 Among them, the workflow of the navigation device of the present invention is as follows:

[0020] a. Start the system and perform initial positioning;

[0021] b. The processor inquires the location information from the differential GP...

Abstract

The invention provides a precision device based on a difference GPS technology. By the utilization of the difference GPS technology, the device for real-time precision positioning is used to carry out real-time interpretation and route alert for tourists. The guiding device is composed of a GPS antenna, a difference GPS receiver, a processor, a memory and an input / output device. Three-dimensional maps or tour guide speeches of a scenic spot or a museum is stored in the memory. When a tourist holds the guiding device in a scenic spot or a museum, the GPS receiver receives the position information of the tourist through the GPS antenna at real time. Then the information is contrasted with the three dimensional maps in the memory to determine which district the tourist is at. Therefore, an appropriate tour guide speech is selected.

Description

Technical field: [0001] The invention belongs to the field of automatic navigation, in particular to an accurate navigation device based on differential GPS technology. Background technique: [0002] With the improvement of people's living standards, people often have higher requirements for the quality of life. When people go sightseeing in various scenic spots, museums, etc., they often need perfect explanations and meticulous tour guides to obtain a more comprehensive experience. In the prior art, tourists are guided by guides or instructions, handbooks, inscriptions, etc. provided at scenic spots, and these explanatory texts are usually closer to the scenic spots. However, when a large number of people want to view the items / works of the scenic spot at the same time or individually in different ways, it is difficult for the existing technology to provide a flexible method. The emergence of intelligent tour guides has solved this problem to a certain extent, but often d...
