随着我国经济的快速发展,高速铁路的建设进入到一个蓬勃发展的时期,而高速动力组列车网络控制技术又是列车快速稳定运行的关键。1999年TCN网络标准被制定出来,加上目前计算机技术、电控技术、微型电子技术的发展,几乎所有的高速动力组列车都采用了网络控制技术。TCN的控制系统具有较高的可靠性,优良的系统柔性,以及更好的交互性,而高速动力组列车控制和传统的工业控制相比具有更复杂的特点,容易出现网络阻塞、数据丢失、信息传输不稳定等问题,这就使得高速动力组列车网络控制的设计显得很困难。本文就目前高速动力组列车网络控制的问题进行了分析,并阐述了这一领域的发展趋势。
With the rapid economic development in our country, the construction of high-speed railway has entered a period of vigorous development, and the network control technology of high-speed power train is the key to the rapid and stable operation of trains. In 1999, TCN network standard was developed. Coupled with the development of computer technology, electronic control technology and microelectronic technology, almost all of the high-speed trains use network control technology. TCN control system has high reliability, excellent system flexibility and better interaction, and high-speed power train control compared with the traditional industrial control has more complex features, prone to network congestion, data loss, Information transmission instability and other issues, which makes high-speed train power train control network design is very difficult. This paper analyzes the current problems of high speed train control network and expounds the development trend in this field.
