基于ETB的列车无线网络的编址寻址方法
Addressing Method of Train Ethernet Based on ETB
【摘要】 随着列车网络技术的高速发展,无线通信将应用于下一代列车网络控制系统中。在IEC 61375 2-5协议基础上提出了以ETB(Ethernet Train Backbone)和ECN(Ethernet Consist Network)为基础的无线列车网络通信结构。针对终端设备之间因列车实际运行需要而进行跨ETB、ECN通信的需求,给出适用于轨道交通专用网络的地址转换(R-NAT)方法,保证跨编组子网之间通信不会出现IP冲突。针对传统编址寻址方式较为复杂的问题,提出了基于偏移量的IP编址方法,提高了编址寻址的速度和准确度。
【Abstract】 With the rapid development of train network technology,wireless communication will be applied to the next generation train network control system.Based on IEC 61375 2-5 protocol,a wireless train network communication structure based on ETB(Ethernet train backbone) and ECN(Ethernet consistent network) is proposed in this paper.Aiming at the requirements of cross ETB and ECN communication between terminal equipment due to the actual operation of trains,this paper presents an address translation(R-NAT) method suitable for rail transit private network to ensure that there will be no IP conflict between cross marshalling subnetworks.Aiming at the complexity of traditional addressing methods,an offset based IP addressing method is proposed to improve the speed and accuracy of addressing.
