现行设计方案采用四显示移频自动闭塞。因区间改造只能按区段一次开通,站场改造又先于区间改造,本着最大限度减少对运输影响的原则,避免二次大封锁,制定的施工过渡方案为软件不变,即站内仍按区间四显示设计一步到位(包括计算机联锁软件),只改硬件(即接口、信号机点灯电路),这样既减少了施工封锁次数,又满足了运输生产的需要。
The current design uses four display frequency shift automatic blocking. Due to the range of transformation can only be opened once by the section, station transformation and transformation of the first section, in line with the principle of minimizing the impact on transport, to avoid a second blockade, the construction of the transition plan for the software unchanged, that station still According to the interval four shows the design step (including computer interlocking software), only to hardware (interface, signal lighting circuit), so that not only reduces the construction blockade, but also to meet the needs of transport production.
