大连轨道交通12号线信号系统控车码序应用研究

Study on the application of control car sequence of signal system in Dalian rail transit line 12

文章针对大连轨道交通12号线实际情况,利用ZPW-2000A轨道电路4种载频发送低频信息,实现控车码序信息码传送,在区间采用大台阶速度控制方式。详细分析了18位控车信息码的定义和设置,探讨了区间、岔区、站台区段、折返线轨道区段的控车码序信息码的编码原则。提出在终端折返站通过增加点式应答器设备,利用58/0A、58/0B特殊码位,采用终端站模式曲线控车方式,提高折返效率。

This paper aims at the actual situation of Dalian rail transit line 12, we use ZPW-2000A track circuit, four carrier frequencies to send low frequency information to realize the transmission of code sequence information code, and adopt large step speed control mode in the interval. The definition and setting of the 18 bits car control information code are analyzed in detail. The coding principle of the code information code of the vehicle control section in the interval, turnaround area, platform section and reentry line segment is discussed. It is proposed to improve the reentry efficiency by adding point transponder equipment and using 58/0A and 58/0B special code bits and by adopting the terminal station mode curve control mode.
