Abstract: By examining the characteristics and technical requirements of the moving block system of Shuozhou-Huanghua heavy haul railway, this paper studies the heavy haul radio block center (RBC) system, and provides a solution for calculating movement authority for heavy haul trains by the moving block method. In view of the greater length and weak braking performance of heavy haul trains, heavy haul RBC provides the following functions: assisted train positioning, train screening, maintaining movement authority, transition between fixed block and moving block without stopping and other functions applicable to heavy haul trains. Through a field test on Shuozhou-Huanghua Railway, it is verified that each function of the heavy haul RBC system meets the technical requirements of the moving block system of the heavy haul railway, which lays a foundation for the development of Smart Shuozhou-Huanghua Railway in the future.

Key words: heavy haul radio block center, assisted train positioning, train screening, maintaining movement authority, transition without stopping

摘要： 针对朔黄重载铁路移动闭塞系统的特点和技术要求，对重载无线闭塞中心（RBC）系统进行研究，实现以移动闭塞方式为重载列车计算行车许可。重载RBC针对重载列车长度长、制动性能弱等特点，研究适应重载列车的列车辅助定位、列车筛选、行车许可保持、固定闭塞与移动闭塞间不停车切换等功能。通过朔黄铁路现场试验，验证重载RBC系统各项功能满足重载铁路移动系统的技术要求，为将来朔黄智慧铁路的建设奠定基础。
