Intelligent tour guide service system with scenic spot and intersection broadcasting function

Abstract

The invention discloses an intelligent tour guide service system with a scenic spot and intersection broadcasting function, comprising a mobile terminal, a mobile communication system, a mobile positioning system and a GIS application server; the GIS application server comprises a module used for processing the broadcasting conflict between scenic spots, the module is used for sieving the most matched effective explaining path by Thiessen polygon technology and multi-round computation so as to accurately determine the scenic spot to be broadcasted; the GIS application server further comprisesa module used for processing the broadcasting conflict bewtene the scenic spot and the intersection, judging the broadcasting mode according to the spatial position information of the scenic spot explaining region and the intersection broadcasting region, subdividing the position relation of the two regions into the following five states: displacement, internally tangent, exterior contact, intersection and inclusion, and regulating a corresponding broadcasting conflict solution condition. The system of the invention has the advantages of effectively solving the explain target conflict problemin the electronic tour guide technology.

Description

technical field [0001] The invention relates to an intelligent tour guide service system, in particular to an intelligent tour guide service system with the function of broadcasting scenic spots and crossings. Background technique [0002] With the development of GPS technology and GIS technology, the intelligent tour guide system is more and more popular among tourists. It can not only meet the needs of tourists for self-guided tours, but also explain scenic spots for tourists, and has become a flexible and fashionable way of tour guides nowadays. . However, in the existing intelligent tour guide service system that uses GPS to provide tour guide service, there is no consideration of how to reasonably divide the scope of explanation of scenic spots, and how to deal with the conflict between the explanation of scenic spots and the broadcast of intersection turning information. For broadcast conflicts between scenic spots, the prior art simply triggers the tour guide service...

AI Technical Summary

Problems solved by technology

For broadcast conflicts between scenic spots, the prior art simply triggers the tour guide service according to the distance relationship between the user's position and the scenic spot's position, such as publication numbers CN101587673, CN1913403, CN102142215A and other patents. There are often problems in use. For example, when the positions of some scenic spots are close together, it is very likely that multiple identical values ​​will appear when calculating the distance between the user's position and the positions of these scenic spots. For the problem of tour guides, although some patents provide solutions to such problems, such as relying on manual methods to divide the appropriate broadcast trigger distance for each scenic spot, and divide the priority of scenic spot broadcasts, etc., but considering its implementation cost and achieve efficiencies, these approaches still have deficiencies

For the broadcast conflict between scenic spots and crossing information, the prior art does not provide a reasonable solution, as the publication number is CN101587673, and the name is "a triggering method for scenic spots based on commentary points in a GPS intelligent tour guide system" The invention patent provides a method of searching all the commentary points in the scenic area according to the set trigger cycle and trigger radius to see if they meet the trigger conditions, and selects a commentary point from the set of commentary points according to the selection rules of the commentary point for voice playback. It only considers how the user triggers the information broadcast of the scenic spot (POI point), and does not consider the path guidance relationship between the scenic spot and the scenic spot (between POI points), which cannot solve the purpose of tourists getting lost in the scenic spot or visiting the best scenic spots; public The invention patent with the number CN101498586 and the title "Application of Intelligent Tour Guide System for Scenic Spot Information Preview and Tour Route Planning Method" downloads the map of the scenic spot and sets a control at each scenic spot location, and tourists click on the control to obtain the scenic spot tour information, and according to the tourists Select the scenic spots to be visited, and use the FLOYD algorithm to display a shortest route connecting all selected scenic spots on the map. Tourists can refer to this route for sightseeing. Although this method provides tourists with a recommended scenic spot tour route, it does not have a real-time guidance function. It is undoubtedly a great pity for tourists who like self-guided tours and in-depth tours
