当前DS6-11计算机联锁设备在全路各条干线上已大量使用,随着铁路的快速发展,大量电化改造和扩能改造的进行,在既有DS6-11计算机联锁设备上进行结合ZPW-2000A、闭环电码化、出发三改四等技术改造施工也越来越多。由于DS6-11计算机联锁结口电路设计的特殊性,对既涉及到软件的修改、又要增加大量继电设备的既有DS6-11的改造施工,如果不在施工前作精心的准备,不采取科学的故障判断方法,仅靠施工时间点.既要完成联锁软件的更换,又要进行大量的拆配线和联锁试验,还不排除有一些比较复杂的故障要进行查找,确保施工的安全与正点难度很大。
At present, the DS6-11 computer interlocking equipment has been widely used on all the main lines of the whole road. With the rapid development of the railway, a large number of electrification transformation and expansion of capacity expansion are carried out. In combination with the existing DS6-11 computer interlocking equipment, ZPW -2000A, closed-loop code, starting three to four technical transformation construction more and more. Due to the particularity of DS6-11 computer interlocking interface circuit design, the reconstruction of existing DS6-11, which involves both the modification of software and the addition of a large number of relay devices, is not taken unless it is carefully prepared before construction Scientific fault judgment method, only by the construction time point. It is necessary to complete the replacement of interlocking software, but also a large number of demolition lines and interlocking test, but also not ruled out that there are some more complex fault to be found to ensure that the construction Safety and punctuality is very difficult.
