基于LTE-R通信和400MHz数字通信的双模列尾技术研究

Research on Dual Communication Mode Solution to End-of-train Safety Equipment Based on LTE-R Communication and 400 MHz Digital Communication

针对国能集团旗下铁路公司重载铁路列车跨线运行存在多种列尾通信制式的问题,在需求调研的基础上,提出基于LTE-R通信和400 MHz数字通信的双模列尾技术方案,并完成设备研制。功能和性能测试表明:该装置可有效提高通信的成功率,满足地方铁路列尾装置应用需求,保障重载铁路运输安全。

To cope with the problem of multiple communication modes for end-of-train safety equipment encountered in cross-line operation of the trains on the heavy-haul railway owned by National Energy Group,a dual communication mode solution to end-of-train safety equipment is proposed based on LTE-R communication and 400 MHz digital communication according to requirement investigation.On basis of this,the end-of-train safety equipment with dual communication mode has been developed and its function and performance have been tested and validated.The test results show that this equipment can effectively improve the rate of communication success and meet the requirements of applying the end-of-train safety equipment in local railways,thus ensuring the safety of railway transportation.
