驼峰辅助复示信号显示方案改进研究

6502电气集中电路是铁路信号联锁系统、联锁逻辑的重要基础。针对6502电气集中电路中驼峰辅助复示信号在驼峰辅助信号开放前进信号后呈现闪光信号的问题,分析驼峰辅助复示信号显示电路的工作原理,研究驼峰辅助复示信号出现闪光信号的原因;从驼峰辅助信号前进信号灯丝断丝是否驱动LXJ的角度提出了4种修改方案,比较了4种方案对原6502电气集中电路的修改范围;以阜阳北三场为应用对象进行试验,结果表明,方案4满足故障-安全的处理原则,可为后续联锁软件相关问题的修改提供参考。

Improvement of display scheme of hump auxiliary repeater signal

The 6502 electric centralized circuit is the important foundation of railway signal interlocking system and interlocking logic. In view of the flash signal of the hump auxiliary repeater signal in the 6502 electric centralized circuit after the hump auxiliary signal opens the forward signal, this article analyzed the principle of hump auxiliary repeater signal display circuit, and studied the cause of the flash signal of the hump auxiliary repeater signal. From the point of view of whether the break of the advance signal filament of the auxiliary signal of the hump drives the LXJ, the article put forward four modification schemes, and compared the modification range of the original 6502 electric centralized circuit by four schemes, carried out the test in the North Fuyang Three Field. The results show that scheme 4 meets the fault - safety processing principle, which can provide reference for the modification of the subsequent interlocking software related problems.
