在列车动态定价补票系统中 ,为保证用户终端与中央服务器的通信安全 ,弥补小数量传输系统在可靠性方面存在的不足 ,文章提出采用严格的通信协议 ,利用矩阵分析方法 ,解决了纠错编码技术应用于小系统时成本高、设计复杂的缺陷。试验测试表明该方案能够克服常规的丢帧现象 ,提高了整个系统数据传输的安全性 。
In the train dynamic pricing system of ticket-buying after normal time, it is suggested that a strict communication protocol should be adopted to ensure the safety of data transmission between user terminal and server and to make up the reliability inadequacy of small-quantity transmission system. Meanwhile, with the help of the matrix analysis method, problems such as high cost and complex design will be solved when the technique of rectification and encoding is applied to small system. Through experimentation, it is tested that this project can overcome the general loss of information, and the safety of data transmission of the entire system can be improved. As a result, it is rather reliable when it is employed in the train dynamic pricing system.
