设备现状苏联已有50％以上的铁路装设了自动闭塞和调度集中。在电气化区段广泛采用频率25或50 Hz交流轨道电路三显示计数电码自动闭塞,而在内燃牵引区段则采用直流脉冲轨道电路三显示计数电码自动闭塞。在自动闭塞区段经常加装连续式机车信号(АЛСН)。为调整同方向运行间隔5min的高速行车(160～200km/h)和一般行车(160km/h以下),曾研制出四显示频率自动闭塞系统,并设有连续式多显示АЛС,保证机车色灯信号机有9种不同显示。多显示АЛС的机车设备加装自动停车,速度监督和检查司机警惕性装置,如设有相应制动设备时,则应加装自动调速装置。
Equipment status The Soviet Union has more than 50% of the railway installed automatic blocking and scheduling focus. In the electrification zone, the frequency of 25 or 50 Hz AC track circuit is widely used to automatically block the counting code, while in the internal combustion traction zone, the DC pulse track circuit is used to automatically display the counting code. In the automatic block section often install continuous locomotive signal (АЛСН). In order to adjust the high-speed driving (160 ~ 200km / h) and general driving (less than 160km / h) in the same direction for 5min intervals, a four-display frequency automatic blocking system has been developed and a continuous multi-display АЛС Signal machine has 9 different display. Multi-display АЛС locomotive equipment with automatic parking, speed monitoring and check the driver vigilance device, if there is a corresponding brake equipment, you should install automatic speed control device.
