1999年元月10日,我段管内马砦-中牟站间共5个区间6个站ZP-89型集中式移频自动闭塞设备开通使用。该设备具有维护、日常测试方便,系统稳定性高等诸多优点,其电路设计也满足了区间及出站红灯转移、区间黄灯(U灯)、绿灯(L灯)灯丝双断(灭灯)时,前方出站信号机能降级显示的功能,但存在当二离去(2LQ)信号机U灯或L灯灯丝双断时出站信号不能降级显示的问题。该问题不解决就可能使高速列车不能在灭灯信号机(2LQ信号点)前停车。造成行车事故。为此,我们将管内5个区间与站内结合电路进行了修改,使问题得以解决。现就郑
On January 10, 1999, ZP-89 centralized frequency-shift automatic blocking equipment was opened at 6 stations in 5 sections of Mazhai-Zhongmou Station in our section. The device has many advantages such as maintenance, daily test convenience and high system stability. Its circuit design also meets the needs of the interval and outbound red light transfer. The interval yellow light (U lamp) and green light (L lamp) , There is a problem that the outbound signal at the front can degrade the display function but the outbound signal can not be degraded when the 2LQ signal U lamp or the L lamp filament is double-interrupted. If this problem is not solved, high-speed trains may not be able to stop before the traffic lights (2LQ signal point). Cause traffic accident. To this end, we will be within the tube and the station within the 5 combined circuit was modified so that the problem can be solved. Now Zheng
