根据铁路技术的现状,我们可以推测出它到二十一世纪时的发展前景。微电子技术是铁路发展的主要推动力之一,因此本文着重讲述微电子技术在铁路应用方面的发展。一、在信号方面的应用 1.运量较小的线路英国铁路不久前建成一个无线电信号系统,可用很少的人力和占地较小的地下建筑物来完成与现在相同的功能。该系统采用了无线电话和计算机。计算机能够安全可靠地把信号传给司机,使得在一个区间内只能有一趟列车的司机能获得行车凭证,从而防止了正面冲突的可能。司机室内有显示装置,可向司机显示,是否能进入这个区间。无线电信号系统向着取消地面信号的方向前进了一步,这对于偏僻地区、运量很小的线路有着重要意义。
According to the status quo of railway technology, we can speculate on its development prospects in the 21st century. Microelectronic technology is one of the main driving forces for railway development. Therefore, this article focuses on the development of microelectronic technology in railway applications. I. SIGNAL APPLICATIONS 1. Less traffic lines British Rail recently built a radio signal system that could accomplish the same function as today with little manpower and smaller underground structures. The system uses a wireless phone and a computer. The computer can safely and reliably relay the signal to the driver so that drivers who have only one train in a range can get driving permits and thus prevent the possibility of a positive conflict. The driver has a display device inside the room, can show to the driver, whether to enter this range. Radio signal system to cancel the direction of the ground signal a step forward, which for remote areas, traffic is very small lines of great significance.
