本文介绍的多语种语音播放电路是多语种讲解系统的一部分,该系统已经在北京颐和园正式运行。下面简要描述该系统的构成和应用,重点介绍多语种语音播放电路及工程应用的思路,供大家参考。 该系统必须满足以下三个要求:第一,要具有在各景点自动播放解说词的功能;第二,系统必须具备多语种播放功能;第三,要求产品具有较强的可操作性,系统采用小范围定点无线发射,游客可租用单频点接收机。 多语种讲解系统分成无线发射和接收两部分。无线发射部分是由直流稳压电源、多语种语音播放电路和多个不同频点的调频发射单元组成;接收部分是由单频点调频接收机构成。
This article describes the multilingual voice broadcast circuit is part of a multilingual explanation system, the system has been officially run in Beijing Summer Palace. The following briefly describes the composition and application of the system, focusing on multi-language voice broadcast circuit and engineering ideas for your reference. The system must meet the following three requirements: first, to have the function of automatically playing the commentary in each attraction; secondly, the system must have the multi-language playing function; thirdly, to require the product to have strong operability, and the system adopts Small range of fixed-point wireless launch, tourists can rent single-frequency receiver. Multilingual explanation system is divided into two parts: wireless transmitting and receiving. Wireless transmitter part is a DC power supply, multi-language voice broadcast circuit and a number of different frequency FM transmit units; receiving part is composed of single-frequency FM receiver.
