具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面参照附图描述根据本发明实施例的道岔转辙联锁保护装置和包括该装置的道岔系统。
图1是根据本发明实施例的道岔转辙联锁保护装置的框图,如图1所示,该道岔转辙联锁保护装置100包括接收模块10、确认模块20、处理模块30和集中控制联锁模块40。
其中,接收模块10,例如转辙启动按钮,用于接收道岔转辙指令,例如,当经过某个道岔的列车进路时,可以通过操作该接收模块10选择该道岔以发出道岔转辙信号。
确认模块20用于接收确认指令,即同意道岔梁锁闭的指令。需要说明的是,接收模块10和确认模块20的具体形式不做限制,可以为单独设置的按钮,或者一个按钮的两次操作,或者其他可实现形式。
处理模块30,例如现有技术中的信号系统,根据道岔转辙指令确定目标道岔位置,并根据确认指令输出确认驱动信号。
集中控制联锁模块40包括确认单元41和位置开关单元42。在集中控制模式下,确认单元41根据目标道岔位置进行道岔单独锁闭并根据确认驱动信号进行锁闭确认。具体地,在经过某个道岔的列车进路时,接收模块10接收操作并发出道岔转辙信号之后,处理模块 30进行运算和选择,确定该道岔空闲且未发生故障,则控制确认单元41动作以单独锁闭该道岔的道岔梁,即其他设备例如信号机或进路的锁闭信号、或其他道岔的控制信号将不做响应,进而,在确认模块20输出确认指令之后,控制确认单元41动作以同意道岔锁闭,例如,同意位置开关单元42作出相应动作以驱动目标道岔进行转辙,即再次进行确认。通过在集中控制联锁模块40中设置确认单元41,进行双重确认,提高安全性。
位置开关单元42在锁闭确认之后,根据目标道岔位置接通目标道岔位置开关且断开除目标道岔位置开关之外的其它的道岔位置开关,以输出目标道岔转辙控制信号,实现联锁保护,从而在目标道岔进行转辙时,其他转辙信号将失效,有效降低风险。
进一步地,如图2所示,确认单元41包括锁闭开关411和确认开关412。其中,锁闭开关411用于在集中控制模式下接收到目标道岔位置时接通以进行道岔单独锁闭,即在接收模块10接收到用户指令输出道岔转辙信号之后,处理模块30进行运算和选择确定目标道岔位置的状态适于列车通行,则控制锁闭开关411接通以进行到道岔的单独锁闭,可以忽略其他的控制信号。确认开关412用于在集中控制模式下接收到确认驱动信号时接通以进行锁闭确认,具体地,在确认模块20接收到用户的确认指令之后,处理模块30控制确认开关412动作,相当于再次确认后同意道岔锁闭。通过锁闭开关411和确认开关412实现双重安全保护,降低转辙风险。
参照图3所示,锁闭开关411为两个,确认开关412为两个。例如,锁闭开关411包括第一锁闭开关KA0408-1和第二锁闭开关KA0408-2,确认开关412包括第一确认开关KA0411-1和第二确认开关KA0411-2。其中,第一锁闭开关,例如KA0408-1,的一端连接第一确认开关,例如KA0411-1,的一端,第一锁闭开关KA0408-1的另一端连接电源正极P,第一确认开关KA0411-1的另一端连接位置开关单元42,第二锁闭开关,例如KA0408-2,的一端连接第二确认开关,例如KA0411-2的一端,第二锁闭开关KA0408-2的另一端连接电源负极N,第二确认开关KA0411-2的另一端连接位置开关单元42。处理模块30根据道岔转辙指令进行运算和选择确定目标道岔位置的状态适于列车通行,则控制KA0408-1和KA0408-2接通,以进行到道岔的单独锁闭,在确认模块20接收到确认指令时,处理模块30控制KA0411-1和KA0411-2接通以进行锁闭确认,从而实现双重安全保证,其他控制信号将不再有效,提高安全性。
进一步地,在本发明实施例中,道岔可以包括双线式、三线式、四线式或者五线式,甚至更多形式的,在此不作具体限制,都可以实现联锁保护。
参照图3所示,对于两个道岔线路的联锁保护,位置开关单元42可以包括第一联锁保护支路和第二联锁保护支路。

在进行转辙控制时,如果目标道岔位置为第一道岔位置,控制第一道岔位置常开开关KA0430-1和KA0430-2上电,而其他道岔位置开关维持下电状态,则第一联锁保护支路的回路接通,输出集中控制第一道岔转辙指令条件至道岔转辙机,实现第一道岔位置的转辙控制,而第二道岔位置位于无效状态。如果目标道岔位置为第二道岔位置,则控制第二道岔位置常开开关KA0436-2和KA0436-3上电,其他道岔位置开关维持当前下电状态,则此时第二联锁保护支路回路接通,输出集中控制第二道岔转辙指令条件至道岔转辙机,实现第二道岔位置转辙控制,而第一道岔位置控制无效,实现联锁保护。
参照图3所示,对于三线式道岔,在上述两个道岔线路的基础上,第一联锁保护支路和第二联锁保护支路分别还包括第三道岔位置常闭开关KA0442-1,其中,在第一联锁保护支路中,第三道岔位置常闭开关KA0442-1的一端与第二道岔位置常闭开关KA0436-1的另一端相连,第三道岔位置常闭开关KA0442-1的另一端与道岔转辙机相连,在第二联锁保护支路中,第三道岔位置常闭开关KA0442-1的一端与一个第二道岔位置常开开关KA0436-2的第一静触点2相连,第三道岔位置常闭开关KA0442-1的另一端与道岔转辙机相连。

在进行转辙控制时,当目标转辙道岔位置为第二道岔位置,则控制第三道岔位置常开开关KA0442-2和KA0442-3上电,而其他道岔位置开关维持下电状态,则第三联锁保护支路回路接通,输出集中控制第三道岔转辙指令条件至道岔转辙机,实现第三道岔位置的转辙控制,而其他道岔位置控制信号无效,达到联锁保护效果。
对于四线式道岔,在上述三线式道岔线路的基础上,第一联锁保护支路、第二连锁保护支路和第三联锁保护支路分别还包括第四道岔位置常闭开关KA0448-1,其中,在第一联锁保护支路和第二联锁保护支路中,第四道岔位置常闭开关KA0448-1的一端与第三道岔位置常闭开关KA0442-1的另一端相连,第四道岔位置常闭开关KA0448-1的另一端与道岔转辙机相连,在第三联锁保护支路中,第四道岔位置常闭开关KA0448-1的一端与第三道岔位置常开开关KA0442-2的第一静触点2相连,第四道岔位置常闭开关KA0448-1的另一端与道岔转辙机相连。
位置开关单元42还包括第四联锁保护支路,第四联锁保护支路包括第四道岔位置常开开关,第四道岔位置常开开关为两个,每个第四道岔位置常开开关包括动触点1、第一静触点2和第二静触点3,一个第四道岔位置常开开关KA0448-2的动触点1与一个第三道岔位置常开开关KA0442-2的第二静触点3相连,第四道岔位置常开开关KA0448-2的第一静触点2与道岔转辙机相连,另一个第四道岔位置常开开关KA0448-3的动触点1与另一个第三道岔位置常开开关KA0442-3的第二静触点3相连,另一个第四道岔位置常开开关KA0448-3的第一静触点2与道岔转辙机相连。
在进行转辙控制时,如果目标道岔位置为第四道岔位置,则控制第四道岔位置常开开关KA0448-2和KA0448-3上电,而其他道岔位置开关维持下电状态,则第四联锁保护支路回路接通,输出集中控制第四道岔转辙指令条件至道岔转辙机,实现第四道岔位置的转辙控制,而其他道岔位置控制信号无效,达到联锁保护效果。
参照图3所示,对于五线式道岔,在上述四线式道岔线路的基础上,第一联锁保护支路、第二联锁保护支路、第三联锁保护支路和第四联锁保护支路分别还包括第五道岔位置常闭开关KA0506-1,其中,在第一联锁保护支路、第二联锁保护支路和第三联锁保护支路中,第五道岔位置常闭开关KA0506-1的一端与第四道岔位置常闭开关KA0448-1的另一端相连,第五道岔位置常闭开关KA0506-1的另一端与道岔转辙机相连,在第四联锁保护支路中,第五道岔位置常闭开关KA0506-1的一端与一个第四道岔位置常开开关KA0448-2的第一静触点2相连,第五道岔位置常闭开关KA0506-1的另一端与道岔转辙机相连。
位置开关单元42还包括第五联锁保护支路,第五联锁保护支路包括第五道岔位置常开开关,第五道岔位置常开开关为两个,每个第五道岔位置常开开关包括动触点1、第一静触点2和第二静触点3,其中,一个第五道岔位置常开开关KA0506-2的动触点与一个第四道 岔位置常开开关KA0448-2的第二静触点3相连,一个第五道岔位置常开开关KA0506-2的第一静触点2与道岔转辙机相连,另一个第五道岔位置常开开关KA0506-3的动触点1与另一个第四道岔位置常开开关KA0448-3的第二静触点3相连,另一个第五道岔位置常开开关KA0506-3的第一静触点2与道岔转辙机相连。
在进行转辙控制时,如果目标道岔位置为第五道岔位置,则控制第五道岔位置常开开关KA0506-2和KA0506-3上电,而其他道岔位置开关维持下电状态,则第五联锁保护支路回路接通,输出集中控制第五道岔转辙指令条件至道岔转辙机,实现第五道岔位置的转辙控制,而其他道岔位置控制信号无效,达到联锁保护效果。
另外,如图3中,每个联锁保护支路上还包括区段锁闭继电器KA0812,用于实现区段锁闭控制。
具体来说,参照图3所示,当经过第一道岔的列车进路时,在发出第一道岔转辙信号之后,经过处理模块30即信号系统联锁计算机运算和选择,控制第一道岔位置常开开关KA0430-1和KA0430-2上电,同时其他道岔位置开关掉电,形成联锁保护。在正常情况下,五个联锁保护支路中只能同时有一路的道岔位置的常开开关有输出,确认开关KA0411动作,在检查道岔单独锁闭条件之后,向室外道岔系统输出道岔转换条件。上述各个开关可以采用继电器形式实现,例如,对于第一道岔位置的联锁保护中动作过程为:电源→锁闭继电器KA0408上电→确认开关即同意道岔锁闭继电器KA0411上电→第一道岔位置常开开关即道岔位置表示继电器KA0430上电→其他道岔位置的位置开关保持下电状态即道岔位置表示继电器KA0436/KA0442/KA0448/KA0506掉电→输出道岔转换条件即将第一道岔位置转辙控制信号发送至道岔转辙机以对第一道岔位置进行转换,实现列车换道。

例如,通过切换模块50切换至应急控制模式时,选择将要转辙的道岔位置即目标道岔位置,例如选择第一道岔位置,此时,第一道岔位置常开继电器L1K上电,输出转辙条件,同时其他道岔位置的常开继电器维持掉电,因而在控制第一应急联锁保护支路接通的同时禁 止其他应急联锁保护支路的控制信号有效,实现应急模式下的联锁保护机制,防止在第一道岔转辙时接收其他转辙信号,造成系统混乱,报错。
总的来说,本发明实施例的道岔转辙联锁保护装置100,增加确认模块20和确认单元41,在进行转辙之前进行锁闭确认,可以更加安全可靠地控制道岔的转辙,防止道岔转辙时,处理模块30再次发送错误转辙信号,并通过位置开关单元42进行联锁保护,有效降低道岔转辙风险。
