摘　　要：当对既有采用二线制继电方向电路的两站一区间车站联锁及自闭系统进行更新改造,并同步调整为采用基于区间综合监控系统(QJK)的四线制方向电路时,若其中一站新建联锁系统直接按正式工程先期启用,则存在该站需同步启用基于QJK的四线制方向电路,而另一车站仍维持既有联锁系统及继电二线制方向电路的情况。针对上述情况,本文提出一种仅利用两线制方向电路中WZJJ和WZCJ继电器调整外部继电电路的过渡方案,可在不增加配置过渡版联锁软件的前提下解决过渡期间2种制式方向电路的兼容问题。When the section station interlocking system and automatic blocking system for the existing two stations adopted with two-wire relay directional circuit are being under upgrading and reconstruction,and they are being under modification simultaneously to adopt the four wire directional circuit based on the section integrated monitoring system(QJK),if the new interlocking system built for one of the stations is put into operation in advance as the formal project,then a situation will exist that the station is required to enable synchronously the QJK based four wire directional circuit with the other station still maintaining its existing interlocking system and relay two wire directional circuit.With regard to the above-mentioned situation,this paper proposes a transition scheme to adjust the external relay circuit by using of WZJJ and WZCJ relays only in two-wire directional circuit,it is able solve the compatibility problem of the two types of directional circuits during the transition period without additional version of the transition interlocking software.
