1问题提出计算机联锁与自动闭塞系统的结合,需要采集接近离去条件反映车站向区间接发列车。1JGJ、2JGJ、1LQJ和2LQJ电路如图1所示。图1接近离去继电器电路图按照通常方法联锁机直接采集1JGJ、2JGJ、1LQJ和2LQJ接点,存在以下问题:1.列车驶入第一接近区段时,2JGJ由于接近联系线路 1 PROBLEMS The combination of computer interlocking and automatic blockade system is proposed. It is necessary to collect the approaching departure conditions to reflect the departure and arrival of trains to the intervals. 1JGJ, 2JGJ, 1LQJ and 2LQJ circuit shown in Figure 1. Figure 1 approach to leave the relay circuit In accordance with the usual method interlock machine direct acquisition 1JGJ, 2JGJ, 1LQJ and 2LQJ contacts, the following problems: 1. When the train approached the first access section, 2JGJ close to the contact line
