DWY系列电铁远动系统 (DWY Telecontrol System for Electrified Railway)已经在电气化铁道沿线获得了非常广泛的应用。本文分析了 DWY系列电铁远动系统通信协议的通信吞吐率 ,针对其在高误码率信道条件下吞吐率较低 ,信道利用率较低的缺点 ,提出了一种基于级联编码技术的扩展电铁远动通信协议 ,经过计算机模拟与仿真 ,证明该扩展协议在通信吞吐率性能上有很大提高
The DWY Telecontrol System for Electrified Railway has gained a very wide range of applications along the electrified railway. This paper analyzes the communication throughput of DWY series tele-communication system. Considering its low throughput and low channel efficiency under the condition of high bit error rate channel, this paper presents a new scheme based on concatenated coding Extending the telecontrol communication protocol of the electric railway, through computer simulation and simulation, it proves that the extended protocol has greatly improved the communication throughput performance
