CIR设备通过地面服务器获取呼叫信息方案的研究

Research on CIR Equipment Obtaining Call Information by Location Server

既有的CIR设备车站呼叫信息是通过本身的GIS数据库获取的,在线路信息有变化的情况下,需要逐台升级CIR设备,工作量大,升级更新时间长。GIS数据制作长期依赖厂家,制作方式不统一,各厂家实现的效果不一致。为此,提出由地面服务器根据机车下传的位置信息向机车发送呼叫信息,从而解决GIS数据制作难度高、维护工作量大的问题。

Station call information of existing CIR equipment can be obtained via its own GIS da tabase. When line data changes, the database of each set of CIR equipment will be upgraded one by one. The preparation of GIS data relies on the providers of GIS for a long time and the ways of data preparation are not uniform so that their results are different from each other. Therefore, it is proposed that the ground server send call information to the locomotive base on location data from the locomotive, thus solving the problems of high difficulty and heavy workload of GIS database preparation.
