对利用AP数据库排除车载无线电台干扰的研究

Research on exclusion of on-board radio interference by AP database

介绍CBTC系统的数据通信网,根据CBTC系统骨干网的双网特性,为轨旁AP建立2个AP数据库,与列车车头和车尾的2套车载无线电台相对应。车载设备中设计一个车载无线电台管理模块,利用轨旁AP数据库排除非法的无线干扰,实现无线覆盖区域间的越区切换,保证切换的安全性和稳定性。

This paper introduced the CBTC Data Communication Network. According to the redundancy of backbone network, it was established two AP databases, which corresponded to two set of on-board radio. The on-board radio management module was designed in on-board equipment to exclude the illegal radio interferences by the AP databases, implemented the handoff between wireless coverage areas, ensure the handoff safety and stability.
