城市信息化离不开公共基础设施建设,中国轨道交通建设起步晚,但起点也高。随着大中城市的不断发展以及奥运会和世博会的召开,中国新建的轨道交通项目无疑在硬件标准上会走在世界前列。而其基础信息传输系统也必须要有前瞻性,能够为未来轨道交通线路延伸和设备升级留下空间。而中国城区人口密度高的特点也影响了轨道交通项目的规划和铺设,对相关的特殊应用如CCTV监控、自动检售票机、公共广播等服务的要求更高。——西门子数字程控通信系统有限公司(SBCS)OTN产品经理包巍
Urban informatization can not be separated from public infrastructure construction. China’s rail transit construction started late, but its starting point is also high. With the continuous development of large and medium-sized cities as well as the holding of the Olympic Games and the World Expo, China’s newly established rail transit project undoubtedly will take the lead in the world in hardware standards. And its basic information transmission system must also be forward-looking, which can leave space for future extension of rail transit lines and equipment upgrades. However, the high density of urban areas in China has also affected the planning and laying of rail transit projects. The requirements for related special applications such as CCTV monitoring, automatic ticket vending machines and public address broadcasting are even higher. - Siemens Digital Program Control Communication Systems Ltd.
