摘要:
CBTC(基于通信的列车控制)系统的VOBC(车载控制器)通过调用预制、存储的线路数据来获取线路信息，其存储的数据称为车载电子地图。车载ATP(列车自动防护)/ATO(列车自动运行)系统以车载电子地图为基础，结合列车自身定位系统的数据，根据移动授权实现列车的安全运行。为满足网络化运营下线路间互联互通的要求，设计了4个车载电子地图传输方案，分别是基于无线传输的线网电子地图方案、基于固定范围的线网电子地图方案、基于行车交路的线网电子地图方案、基于行车交路的单线电子地图方案。从车载电子地图的传输范围和运营交路角度对全线网车载电子地图进行“切片”和“订制”处理，并对4个方案进行了对比分析，得到结论如下：只有1~2条互联互通线路的线网宜选用基于无线传输的线网电子地图方案；有3条及以上互联互通线路的线网宜选用基于固定范围的线网电子地图方案和基于行车交路的单线电子地图方案。
Abstracts:
The VOBC (vehicle on-board computer) of CBTC (communication based train control) system obtains line information through invoking prefabricated and stored line data, i.e, the on-board electronic map. Based on which and combined with the self-positioning system data, the on-board ATP/ATO system realizes train safe operation through mobile authorization. To meet interoperation requirements between lines in the context of networking operation, 4 electronic map schemes are designed, including wireless communication network based scheme, fixed range based scheme, routing transmission based scheme and a single line electronic map scheme based on routing transmission. The on-board electronic map of the whole network is ′sliced′ and ′customized′ from the perspective of electronic map transmission range and operation routing, then 4 schemes are comparatively analyzed. It is concluded that a network with only one to two interoperating lines should select the electronic map scheme based on wireless transmission; a network with three or more interope-rating lines should select the electronic map transmission scheme based on fixed range and the single line electronic map scheme based on routing transmission.
