【挑战一】基于行空板、Mind+图形化编程的公交语音广播及交互系统 简单

头像 豆爸 2022.10.19 1107 3

1 项目背景

 

对于公交车而言，一套完整的到站语音广播及交互系统能给乘客提供良好的用户体验。本系统旨在通过星空板、Mind+图形化编程，模拟实现公交语音广播及交互系统。

 

 

2 系统架构

 

本系统由司乘语音广播终端、乘客人机交互终端、公交站点交互终端组成。

 

 

 

3 系统功能

 

车载语音广播终端：设置于公交车驾驶位附近，用于实现列车进站、出站手动TTS语音广播、自动TTS语音广播（未开发）、人工话筒广播（未开发）；并驾驶员显示公交线路、列车运行方向、站点等信息显示。

 

乘客人机交互终端：设置于公交车下客车门附近，用于向乘客显示公交线路、行驶方向、到达站点等信息，并设置按钮，用于乘客提醒驾驶员有乘客在前方站点下车。

 

公交站点交互终端：设置于公交站点，用于向乘客显示线路公交车辆线路信息、车辆位置、运营时间等。

 

 

4 硬件设计

 

司乘语音广播终端：行空板 1 块，USB免驱3W小喇叭 1块

 

 

乘客人机交互终端：行空板 1 块，按钮模块 1块

 

 

公交站点交互终端：行空板 1 块，USB免驱3W小喇叭 1块

 

硬件介绍

 

（1）行空板    

 

行空板

 

行空板是一款拥有自主知识产权的国产教学用开源硬件，采用微型计算机架构，集成LCD彩屏、WiFi蓝牙、多种常用传感器和丰富的拓展接口。同时，其自带Linux操作系统和python环境，还预装了常用的python库，让广大师生只需两步就能开始python教学。
