海青线GSM-R复杂地段无线覆盖及频率规划分析

Analysis of GSM-R Wireless Coverage and Frequency Planning for Haitian-Qingdao Line

无线覆盖和频率规划情况直接关系到GSM-R系统能否实现预期功能以及系统能否稳定运行。新建海青线上跨胶济客专后接入胶济线,形成三角地带,对此特殊地段的无线覆盖和频率规划进行了研究分析,提出了切实可行的解决方案,保障新建及既有GSM-R系统的安全性和可靠性,为今后相似工程的设计提供参考。

The wireless coverage and frequency planning are directly related to whether the GSM-R sys- tem can achieve expected function and whether the system can operate stably. After crossing the Qingdao- Jinan passenger dedicated line, the Haitian-Qingdao railway is connected with the Qingdao-Jinan line, forming a triangle zone. This paper analyzes the wireless coverage and frequency planning of this special area, and proposes a feasible solution to guarantee the safety and reliability of the newly-buih and existing GSM-R system, providing a reference for similar engineering design in the future.
