本文的目的是设计一种使用较低的制造和维护成本的公交语音报站系统,并使之实现智能公交的部分基本功能。本文首先提出了公交车语音报站系统的总体设计方案,然后以车载终端的硬件平台的构建和软件设计构架为主要内容,对显示模块、语音模块等功能模块进行了详细的说明。接着介绍了车载终端的调试、使用过程。设计的主要成果是车载终端的实验板,它具备语音手动报站和自动报站、站数显示等功能,它可以作为一种低成本的自动语音报站系统被用于各种公交车上。
The purpose of this paper is to design a public address system that uses lower manufacturing and maintenance costs and to enable some of the basic functions of intelligent public transportation. In this paper, the overall design of bus voice station system is first proposed. Then, the functional modules of display module and voice module are described in detail with the hardware platform of vehicle terminal and the software design framework as the main contents. Then introduced the vehicle terminal debugging, use process. The main result of the design is the vehicle board terminal board, which has the functions of manual voice reporting and automatic reporting, station number display, etc. It can be used as a low-cost automatic voice reporting system in various buses.
