Intelligent electronic tour guide system based on wireless sensor network and method of intelligent electronic tour guide system based on wireless sensor network

Abstract

The invention discloses an intelligent electronic tour guide system based on a wireless sensor network and a method of the intelligent electronic tour guide system based on the wireless sensor network. The system comprises two parts of a host machine and slave machines; wherein the host machine is provided for a tour guide; the slave machines are provided for tourists; the host machine is composed of a microprocessor, a wireless digital radio frequency transmitting and receiving module, an FM frequency modulation transmitting module, a display warning module, a keyboard module and an MCI; the slave machines are composed of microprocessors, wireless digital radio frequency transmitting and receiving modules, FM frequency modulation receiving modules, display warning modules, keyboard modules and earplugs; and the host machines are often installed in boxes. According to the system and the method, the defects in the prior art that the maintenance is difficult, the architecture of damaging a base and the complex decomposition are avoided; it is unnecessary to request to a background terminal for allowing audio communication when audio communication is necessary, therefore, the transmission efficiency of the transmission line is improved, and the tour guide can timely acquire corresponding reactions after the tour guides acquire the host machine.

Description

technical field [0001] The invention belongs to the technical field of electronic tour guides, and in particular relates to an intelligent electronic tour guide system and method based on a wireless sensor network. Background technique [0002] The intelligent electronic tour guide system includes two parts, the host computer and the slave computer.

[0003] The tour guide's commentary is collecte...

AI Technical Summary

Problems solved by technology

[0004] The base is a very common support device, and the guide often connects the box through the base to allow the host to set the position, so that the box can better prevent particles and impurities from being involved in the space where the host is located. On the other hand, after erecting the box body on the base, it is often necessary to extend the fingers into the box body to perform maintenance on the host. It is very difficult. In addition, because the box body is the final assembly process, the connection with the base must be combined with rivets. The structure of the base will inevitably be damaged, and it will also cause cumbersome disassembly.

[0005] In addition, in the case of a large number of tour guides so far, several tour guides need to conduct audio communication in real time, so it needs to be combined with the MCI collected by the host and input to the FM frequency modulation transmitter module, and then transmitted, so that it can be realized for the tour guide on-site The collected audio information is used for audio communication. However, with the increasing demand for audio communication of several tour guides, once a large number of tour guides perform audio communication in real time and synchronously, they will often interfere with each other, and the audio of specific tour guides cannot be identified at all. Audio communication is not possible

[0006] In order to solve this problem, the tour guide uses the host's MCI acquisition alone for audio communication, which leads to the problem of inefficient use of the host's MCI acquisition. Although in order to solve this problem, a background terminal is also introduced to operate the audio signal Sending and receiving, which will often increase the amount of transmitted signal and affect the transmission efficiency of the transmission line; in addition, the audio signal may be distorted due to the lag of the transmission line
