摘　　要：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。According to the current design scheme, the block system is an automatic block of 4-aspect shift frequency. Since section of reconstruction must be commissioned in one time by segment and the station/yard reconstruction is earlier than section reconstruction, in the principle of reducing its influence to transportation to the maximum extend and avoiding the second system blockage, the construction transit scheme is designed as one with no change on the software, i.e. 4-aspect for section is adopted in station （including computer interlocking software）, and change only with the hardware （namely interface and lighting circuit for signals）. Thus, not only the times of construction blockage are reduced, but also the demands of transport and production are met.
