Interactive wireless electric tour guide system and method

Abstract

The present invention provides a interactive wireless electric guide system, which includes emitting set and portable receiver, emitting set includes master controller MCU and guide information memory connecting with it, first radio frequency module; portable receiver includes digital signal processor, random memorizer, nonvolatile store, second radio frequency module, programmable logic device and playback module, the first radio frequency module controlled by main controller, second radio frequency module controlled by digital signal processor according to communication protocols automatic switchover frequency channel, so communication interactive is completed. The present invention has the advantage of low cost, easy to update system maintenance and guide information, realizing automatic recognition sight by user end, taking photo at any time, standard, personalized and intelligentize of tour serves are realized.

Description

technical field [0001] The invention relates to an electronic tour guide device and a tour guide method based on wireless communication technology, voice signal coding and decoding technology, and digital signal processor embedded system technology, and belongs to the field of wireless interactive electronic tour guide equipment manufacturing. Background technique [0002] In recent years, with the development of internationalization, electronicization, intelligence and networking of tourism services, many tourist attractions have begun to introduce electronic tour guide technology, among which more advanced electronic tour guide devices basically use wireless transmitters and portable receivers Combined mode, in terms of signal transmission and control, there are mainly the following two methods: [0003] One is to adopt the local voice storage mode, such as "Intelligent Tour Guide Explaining System and Its Working Method" with Publication No. CN101018062, "Intelligent Elec...

AI Technical Summary

Problems solved by technology

There are three main defects in this technology: 1) all the explanation content is stored in the receiver, which requires a large-capacity non-volatile memory chip, which increases the cost of the receiver. In addition, if you want to change the explanation content, you must It is very inconvenient to rewrite with one receiver; 2) Using infrared transmission technology, the distance is short and directional, and it is easy to be blocked by other tourists so that the receiver cannot receive correctly. If GPS is used for precise positioning, the receiver will be added 3) The use of infrared technology cannot realize the interactive function between the transmitter and the receiver. If GPRS and other navigation technologies are used, additional GPRS information costs will be generated

Both of these systems are designed for tour guides with group tours. The tour guides hold the launcher to explain, and the tourists carry receivers to listen. The biggest problem is: 1) they cannot provide multilingual tour guides at the same time; Started to listen to the explanation; 3) did not consider the self-help travel of individual tourists; 4) the service quality is still affected by the personal tour guide
