摘要
针对北京地铁1、2号线地铁电视和PIS系统工程的特殊性、现场工况的复杂性和功能的多样性,重点介绍了地铁电视系统设计方案。针对现有轨道交通实际采用的PIS车-地传输方案固有的局限性及缺点,探讨了地铁电视系统无发射机(DVB-T)设计方案在车-地传输方面应用的可行性及优点。
This paper focus on the design of Metro TV and PIS system for Beijing subway line 1 and line 2 in the light of engineering specialty of Metro TV and PIS system, the complexity of field environment, and the diversity of functionalities. In view of the inherent limitations and shortcomings of existing PIS transmission system between vehicle and station, this paper discuss the feasibility and benefits of apply- ing train-wayside transmission without transmitter, i. e. DVB-T.
