铁路控制分为三代:1)较早的电机械控制;2)中央计算机控制;3)分布计算机控制。在第二代控制中,铁轨分为若干段,应用计算机探测前面各路段的路轨上是否有列车,并发送必要的信息给各调度点上的列车。 本研究课题的目的是确立第三代铁路控制系统。课题的基本想法是识别每列火车和开关。此法免除了无效的路轨探测和离散的调度方法。为了建立分布计算机控制的铁路系统,列车上应配备有计算机,用开关控制处理机探测并控制开关,主计算机能同各列车和开关进行通讯联系。本文提出分布计算机控制铁路(DCCR)的主要想法和任务,以及给出业已进行的实验结果。
Railway control is divided into three generations: 1) earlier electromechanical control; 2) central computer control; 3) distribution of computer control. In the second generation of control, the railroad track is divided into several sections, and the computer is used to detect whether there are trains on the tracks in front of the sections and send the necessary information to the trains at each scheduling point. The purpose of this research project is to establish a third generation railway control system. The basic idea of the task is to identify each train and switch. This method eliminates inefficient track detection and discrete scheduling methods. In order to establish a distributed computer control of the railway system, the train should be equipped with a computer, with the switch control processor to detect and control the switch, the host computer can communicate with the train and switch. This paper presents the main ideas and tasks of distributing computer controlled railroads (DCCRs) and gives the results of the experiments that have been conducted.
