信息技术已经成为当今社会的主流技术。及时、准确地得到需要的信息是很多客户的要求。无线局域网(WLAN)是相当便利的数据民用通信传输系统。随着WLAN技术的普及,如何将其融合到城市轨道交通环境中去,更好地为乘客信息系统、乘客个人终端服务,已经成为一个新的课题。车地通信的实现是WLAN能够在城市轨道交通中成功应用的关键。针对不同的模式对WLAN的应用进行了阐述,以寻找最适合上海轨道交通系统的应用方案。
In leading the modem society, the information tech- nique has been the main current. Most customers request to get the information about what they need timely and correctly. Wireless local area network（WLAN） is a very convenient data communication transmission system. Along with the application of WLAN technique, it becomes a new topic that how to adapt it to the environment of metro, and how to serve the PIS system in metro and the passenger＇s personal terminal the best. To realize the communication between the train and the station, it is the crux of the successful application of WLAN technique in metro. In this paper the author elaborates the application of WLAN in different patterns and looks for the most suitable plan for Shanghai Metro.
