摘要
通过研究WTB总线通信机制,解决WTB总线带宽利用率低的问题。提出了利用TCN消息通信机制以及过程数据通信机制,实现WTB总线数据通信的网关软件程序设计。对WTB总线传输的数据量的通信时间计算分析、实验表明,该通信方式增加了基本通信周期内WTB总线传输的数据量,提高了WTB总线带宽利用率。利用TCN消息和过程数据的网关程序设计方式降低了大容量数据在WTB总线上的传输延时和程序开发的复杂度,保证了列车网络系统的可靠性。
By studying the communication mechanism of WTB bus, the problem of low bandwidth utilization of WTB bus was solved. The gateway software programing for WTB bus data communication was proposed by using TCN message communication mechanism and process data communication mechanism. The calculation and analysis of communication time and experimental verification of the data amount transmitted by WTB bus showed that the communication mode increased the data amount transmitted by WTB bus in the basic communication cycle, and improved the bandwidth utilization of WTB bus. The gateway programming method of TCN message and process data reduced the transmission delay of large capacity data on WTB bus, reduced the complexity of program development and ensured the reliability of train network system.
