智能交通车站呼叫系统的设计与实现

摘要

车站呼叫系统是智能交通系统的重要组成部分,旨在为乘客在固定
站点进行车辆呼叫提供便利的人机交互接口。该系统分为车站人机交互
终端和中央控制室上位机信息管理平台两大部分。
本文首先设计了车站人机交互终端,该终端以 S3C44B0X 处理器和
µC/OS-II 嵌入式操作系统为软硬件平台;并开发了以中央控制室主机为
核心的集中控制式智能交通系统局域网通信系统。在成功移植嵌入式操
作系统的基础上,开发并实现了车站人机交互终端所需的三大功能:应
用矩阵键盘循环扫描法实现了按键信息的识别;利用灰度液晶实现了相
关信息的显示;使用 UDP 协议实现了车站人机交互终端与中央控制室
上位机之间的信息传递。
在中央控制室主机方面,应用 Visual C#开发环境开发出了呼叫信息
管理软件,该软件选择 MySQL 数据库作为呼叫信息管理的数据库平台。
呼叫信息管理软件实现了监听实时车站呼叫信息、操作数据库系统、刷
新和显示呼叫信息等功能,同时支持手动添加呼叫信息的功能,并集成
了对短信呼叫信息进行管理的功能。

DESIGN AND REALIZATION OF THE STATION
CALLING SYSTEM FOR INTELLIGENT
TRANSPORTATION SYSTEM

ABSTRACT

Station calling system is a key part of intelligent transportation system,
which aims to provide a convenient human machine interface for passengers
to call vehicles in settled stations. This system could be divided into two
parts, viz. the station human machine interface terminal and the information
administration platform in the puter of central control room.
The station human machine interface, whose hardware and software
platforms are made up of S3C44B0X processor and µC/OS-II embedded
operating system, is designed firstly. Using infrastructure mode LAN whose
core is the puter of the central control room, munication
system for intelligent transportation system is developed. Based on
replanting the embedded operating system essfully, three functions
station human machine interface terminal needed are developed and realized:
key-press information identification is realized by the matrix keyboard
