摘　　要：四显示自动闭塞区段,车站计算机联锁一般需要3个闭塞分区作为接近轨道,当两站之间距离较短,少于3个闭塞分区时,则需要对接近轨的逻辑电路进行特殊处理。以神头站至大新站短区间为例,介绍以大新站进站信号机至出站信号机之间作为神头站的1JG、大新站出站信号机至1LQG为神头站的2JG的特殊情况,详细分析接近轨道电路的原理,并对具体工程应用进行说明。As for four-aspect automatic block district, three block sections are generally needed to serve as the approach track in station computer-based interlocking system. And if the distance is short and the number of block sections is less than three between two stations, the logic circuit of approach track should be processed specially. This paper, taking the short section between Shentou station and Daxin station as example, introduces the special circumstances in which the section from the home signal to the starting signal of Daxin station serves as the 1JG of Shentou station while the section from the starting signal of Daxin station to the ILQG serves as the 2JG of Shentou station. At the same time, this paper analyzes in detail the principle of the track circuit of approach track, and describes the specific engineering application of it.
