Problems solved by technology

However, a large number of tour guides will put a lot of pressure on management, so an electronic device is needed that can replace manual tour guides to the greatest extent. In the traditional way of explaining, tour guides explain through traditional loudspeakers, and the sound quality of the explanation is not clear. The work pressure of tour guides is high, but the existing multi-channel wireless broadcasting partition explanation system can only conduct audio broadcasting explanations in order, and cannot enable tourists to listen to what they want, without the integrity and continuity of audio explanations

Abstract

The invention discloses a multi-channel wireless radio system which comprises a wireless explaining player covering channels from 64 to 256 and wireless explaining controllers. Each wireless explaining controller comprises a shell and a control circuit arranged in the shell, and the control circuit comprises a power circuit, a radio frequency identification module, a key decoding circuit, a FLASH storage, a CPU, an audio decoding circuit, a D / A conversion unit and an audio amplifier. By means of the wireless explaining player covering the channels from 64 to 256, frequency signals of different channel conversion control signals are sent to exhibition areas or scenic spots of multiple areas, tourists in the corresponding areas receive the frequency signals through the wireless explaining controllers, the control circuits are activated to be connected with the corresponding CPUs, so that audio content and / or video content of the FLASH storages can be called out and completely and continuously played, the tourists can hear explaining information of the scenic spots or the exhibition areas clearly and completely, the adjacent scenic spots or the adjacent exhibition areas do not interfere with each other and the tourists themselves cannot interfere with each other.

Description

technical field [0001] The invention belongs to the technical field of combined audio-visual advertisement or display, and in particular relates to a multi-channel wireless broadcasting system suitable for museums, tourist attractions, former residences and other tourist places. Background technique [0002] With the vigorous development of the tourism industry and the large increase of tourists, the service requirements of tourist places are getting higher and higher, especially the demand for the number of tour guides is increasing. However, a large number of tour guides will put a lot of pressure on management, so an electronic device is needed that can replace manual tour guides to the greatest extent. In the traditional way of explaining, tour guides explain through traditional loudspeakers, and the sound quality of the explanation is not clear. The work pressure of tour guides is high, but the existing multi-channel wireless broadcasting partition explanation system ca...
