摘要
国内万吨以上重载组合列车普遍采用分布式动力机车无线同步操控系统实现牵引制动,无线通信通常采用GSM-R车载终端+数传电台设备或LTE车载终端+数传电台设备,双套设备保证了无线通信的可靠性,但是双套设备独立控制,逻辑复杂,不利于快速切换,难以实现重联机车在GSM-R与LTE线路互通。针对以上情况,采用了多通信技术冗余的一体化平台,统一控制GSM-R,LTE,数传电台等通信单元,并在国铁多个区段进行了测试,结果表明一体化平台完全可以满足通信的可靠性,相比既有系统逻辑简单、成本低,尤其是可支持GSM-R,LTE等多种不同通信方式的线路。
In China,distributed power locomotive wireless synchronous control system is widely used for traction and braking of a heavy haul train which weighs over 10,000 tons.Wireless communication usually adopts GSM-R vehicle terminal with digital radio equipment or LTE vehicle terminal with digital radio equipment.The two sets of equipment guarantee the reliability of wireless communication,but the independent control and complex logic of the two sets of equipment are not conducive to rapid switching,and it is difficult to realize the GSM-R and LTE railway section of reconnection locomotive.For the above situation,an integrated platform of various communication redundant technology was adopted to control GSM-R,LTE,digital radio or other communication units,and was tested in several sections of the national railway.The results show that the integrated platform can satisfy the reliability of communication;Compared with the existingsystem,it has more simple logic and lower cost.In particular,it can support GSM-R,LTE and the railway section of other communication modes.
