电梯在开门过程中的平层功能，俗称提前开门功能，通常用于乘客电梯，其目的是为了节省时间，提高运行效率。开门过程中的再平层功能，指电梯到达门区停止后，允许在装卸载期间进行校正轿厢停止位置的操作，其目的是为了补偿货物或搬运车辆进出轿厢造成曳引钢丝绳伸缩导致的轿厢少量升降，使轿厢地坎和层站地坎基本水平，方便货物或搬运车辆进出。轿厢在门区位置处于开门的状态时，驱动器无任何运行指令，需保证轿厢不发生意外移动，以保护人员和物品。
现有的电梯系统中，提前开门、再平层和轿厢意外移动保护功能大多使用纯继电器方式实现。然而，纯继电器实现方案使用的安全继电器成本较高，并且，在上述纯继电器方案中，电梯的轿厢每经过一个楼层，继电器都会动作一次，导致提前开门模块的寿命难以保证。

 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，是本发明实施例提供的电梯安全运行方法的流程示意图，该方法可应用于电梯主控制器，并与连接到电梯主控制器的安全功能装置配合，实现轿厢的提前开门或再平层。本实施例的方法包括：
步骤S11：实时检测第一门区信号和第二门区信号。在本实施例中，当轿厢到达门区时，第一门区信号和第二门区信号为门区有效信号（例如高电平），而当轿厢离开门区，第一门区信号和第二门区信号则为无效信号（例如低电平）。
具体地，上述第一门区信号可通过上门区信号传感器输出，第二门区信号可通过下门区信号传感器输出，上门区信号传感器和下门区信号传感器位于上平层传感器和下平层传感器之间，且上门区信号传感器和下门区信号传感器的门区有效信号分别由井道内的隔磁板触发，如图2所示。当然，在实际应用中，上述第一门区信号和第二门区信号也可通过其他方式生成。
步骤S12：在检测到第一门区信号和第二门区信号均为门区有效信号时，根据门区有效信号和电梯运行状态生成封门开关组闭合指令，并将封门开关组闭合指令发送至安全功能装置，以使安全功能装置控制封门开关组短接门锁回路，从而便于轿门开启操作。
上述安全功能装置连接到电梯主控制器，且该安全功能装置包括连接到门锁回路的封门开关组。为提高安全性，封门开关组包括至少两个封门继电器，且上述封门继电器的主触点与门锁回路中的门锁开关并联连接。该安全功能装置可执行来自电梯主控制器的封门开关组闭合指令，控制封门开关组短接门锁回路。
步骤S13：在接收到来自安全功能装置的封门反馈信号时，执行提前开门或再平层操作。
上述安全功能装置的封门开关组中的封门继电器可采用双触点继电器，且该双触点继电器的主触点与门锁回路中的门锁开关并联连接，安全功能装置可根据双触点继电器的辅触点获得双触点继电器的主触点的状态，即封门开关组的状态。具体地，当安全功能装置在确认封门开关组中所有的封门开关闭合（即双触点继电器的主触点闭合）时，向电梯主控制器发送封门反馈信号。
上述电梯安全运行方法根据第一门区信号、第二门区信号以及电梯运行状态控制封门开关组短接电梯门锁回路中的门锁开关，大大降低了封门开关的动作次数，提高了相关硬件的使用寿命。
在本发明的一个实施例中，上述步骤S12中的根据门区有效信号和电梯运行状态生成封门开关组闭合指令，具体可包括：根据门区有效信号，在电梯轿门处于打开状态且上平层传感器或下平层传感器信号无效时，生成封门开关组闭合指令。通过该方式，可在货物或搬运车辆进出轿厢而导致曳引钢丝绳伸缩，导致轿厢的上平层开关或下平层开关离开门区时，使轿门保持开启状态，从而可进行再平层操作。
在本发明的一个实施例中，在根据门区有效信号和电梯运行状态生成封门开关组闭合指令之前，还包括：接收来自安全功能装置的封门开关组的状态信号；上述状态信号由安全功能装置根据封门开关组中各个封门开关的状态生成。相应地，在步骤S12中，电梯主控制器可在第一门区信号和第二门区信号均为门区有效信号、且封门开关组中的所有封门开关有效时（即不存在失效的封门开关），根据门区有效信号和电梯运行状态生成封门开关组闭合指令。
如图3所示，是本发明另一实施例提供的电梯安全运行方法的流程示意图，该方法可应用于安全功能装置，该安全功能装置可与电梯主控制器配合，实现轿厢的提前开门或再平层。该安全功能装置包括连接到门锁回路的封门开关组。为提高安全性，封门开关组包括至少两个封门继电器，且上述封门继电器的主触点与门锁回路中的门锁开关并联连接。本实施例的方法包括：
步骤S31：在接收到来自电梯主控制器的封门开关组闭合指令时，控制封门开关组闭合以短接门锁回路，上述封门开关组闭合指令由电梯主控制器根据第一门区有效信号和第二门区有效门区信号以及电梯运行状态生成。
具体地，上述第一门区信号可通过上门区信号传感器输出，第二门区信号可通过下门区信号传感器输出，上门区信号传感器和下门区信号传感器位于上平层传感器和下平层传感器之间，且上门区信号传感器和下门区信号传感器的门区有效信号分别由井道内的隔磁板触发，如图2所示。当然，在实际应用中，上述第一门区信号和第二门区信号也可通过其他方式生成。
步骤S32：在封门开关组闭合后，向电梯主控制器发送封门反馈信号，使电梯主控制器执行提前开门或再平层操作。
上述安全功能装置的封门开关组中的封门继电器可采用双触点继电器，且该双触点继电器的主触点与门锁回路中的门锁开关并联连接，安全功能装置可根据双触点继电器的辅触点获得双触点继电器的主触点的状态，即封门开关组的状态。具体地，当安全功能装置在确认封门开关组中所有的封门开关闭合（即双触点继电器的主触点闭合）时，向电梯主控制器发送封门反馈信号。
上述电梯安全运行方法在电梯主控制器控制下，对门锁回路中的门锁开关进行短接，大大降低了封门开关的动作次数，提高了相关硬件的使用寿命。
在本发明的另一实施例中，安全功能装置还实时检测第一门区信号和第二门区信号，并在检测到第一门区信号为门区无效信号或第二门区信号为门区无效信号时，控制封门开关组失电断开。即在轿厢离开门区时，禁止将轿厢门强行开启，从而实现轿厢意外移动保护。
安全功能装置还检测封门开关组的状态，并发送封门开关组的状态信号至电梯主控制器；并在封门开关组中任意一个或多个失效时，控制封门开关组断开。通过上述方式，可避免封门继电器反复开闭，提高封门接触器的使用寿命。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。如图3所示，是本发明实施例提供的电梯安全运行系统的示意图，该电梯安全运行系统用于实现电梯系统安全可靠地提前开门或再平层。结合图2所示，上述电梯系统包括上门区信号传感器21和下门区信号传感器22，上述上门区信号传感器21和下门区信号传感器22位于上平层传感器23和下平层传感器24之间，且上门区信号传感器21和下门区信号传感器22位于不同高度位置。上门区信号传感器21、下门区信号传感器22、上平层传感器23和下平层传感器24可安装到轿厢，并跟随轿厢上行和下行。具体地，上门区信号传感器21和下门区信号传感器22的输出信号可分别由井道内的隔磁板20触发跳变，例如在上门区信号传感器21和下门区信号传感器22在跟随轿厢运行时，若到达隔磁板20所在区域，则其输出信号由无效（例如低电平）跳变到有效（例如高电平），在离开隔磁板20所在区域，则输出信号由有效跳变为无效。
本实施例的电梯安全运行系统可包括电梯主控制器41和安全功能装置42，上述安全功能装置42可集成到一个可编程电子装置，该可编程电子装置与电梯主控制器41通信连接（例如通过CAN总线）。上述可编程电子装置具体可包括逻辑控制单元421、开关控制单元422以及封门开关组423，其中逻辑控制单元421可由微控制单元并结合在其上运行的软件构成。此外，上述安全功能装置42还可包括供电电路、加密电路、过压及欠压监控电路等。
本实施例的电梯安全运行系统可应用于单开门的电梯系统（即电梯系统的轿厢包括单个轿门，且在该电梯系统的电梯门锁回路中仅包括一个轿门锁开关GS和一组层门锁开关DS，且轿门锁开关GS的尾端连接到层门锁开关DS的首端）中时，本实施例的电梯安全运行系统还包括用于连接轿门锁开关GS的首端的第一外接端子SO1、用于连接层门锁开关DS的尾端的第二外接端子SO2。
相应地，上述封门开关组43包括第一双触点继电器和第二双触点继电器（即封门开关由第一双触点继电器和第二双触点继电器构成），且第一双触点继电器包括常开的主触点KM1-1和常闭的辅触点KM1-2、KM2-2，第二双触点继电器包括常开的主触点KM2-1和常闭的辅触点KM2-2。并且第一双触点继电器的主触点KM1-1的一端和第二双触点继电器的主触点KM2-1的一端短接，第一双触点继电器的主触点KM1-1的另一端连接第一外接端子SO1，第二双触点继电器的主触点KM2-1的另一端连接第二外接端子SO2。当然，在实际应用中，上述封门开关组423中的封门开关也可采用普通继电器或其他开关设备，封门开关的数量也可根据需要进行调整。
逻辑控制单元421连接到上门区信号传感器21和下门区信号传感器22的输出端，从而逻辑控制单元421可实时获取上门区信号传感器21的输出信号FL1和下门区信号传感器22的输出信号FL2。具体地，上门区信号传感器21和下门区信号传感器22的输出端与逻辑控制单元421之间可连接有隔离器件（例如光耦等），以满足逻辑控制单元421的输入电平要求。该逻辑控制单元421还与电梯主控制器41连接（例如通过CAN总线等），以与电梯控制器41进行信息交互。具体地，逻辑控制单元421可在接收到来自电梯主控制器41的封门指令时，生成门锁短接信号。
开关控制单元422用于在接收到来自逻辑控制单元421的门锁短接信号时，控制封门开关组423中的封门开关，即第一双触点继电器的主触点KM1-1和第二双触点继电器的主触点KM2-1闭合，以短接电梯门锁回路中的层门锁开关DS和轿门锁开关GS。此时电梯主控制器可执行开门操作。结合图2所示，由于在上门区信号传感器21和下门区信号传感器22抵达隔磁板20所在区域时，上平层传感器23和下平层传感器24中的一个还未到达隔磁板20所在区域，此时执行开门操作，可大大提高电梯的运行效率。若轿厢本来就处于平层位置，则配合电梯主控制器41，可实现再平层操作。
此外，逻辑控制单元421还可实时检测上门区信号传感器21的输出信号FL1和下门区信号传感器22的输出信号FL2，并在上门区信号传感器21的输出信号FL1和下门区信号传感器22的输出信号FL2中任意一个为门区无效信号时，不向开关控制单元422发出门锁短接信号，从而实现轿厢意外移动保护功能。
上述电梯安全运行系统由逻辑控制单元421根据上门区信号传感器21和下门区信号传感器22的输出信号控制封门开关组423短接电梯门锁回路中的门锁开关，大大降低了封门开关的动作次数，提高了相关硬件的使用寿命。
在本发明的一个实施例中，开关控制单元422具体可包括用于实现第一双触点继电器的主触点KM1-1的通断控制的第一开关控制回路和用于实现第二双触点继电器的主触点KM2-1的通断控制的第二开关控制回路。并且，逻辑控制单元421连接到第一双触点继电器的辅触点KM1-2和第二双触点继电器的辅触点KM2-2，并根据辅触点KM1-2、KM2-2的状态向电梯主控制器41反馈第一双触点继电器的主触点KM1-1和第二双触点继电器的主触点KM2-1的通断状态。通过上述方式，可提高电梯系统在执行提前开门和再平层操作的安全性。
具体地，上述第一开关控制回路包括第一光耦和第一开关管Q1，其中第一光耦的原边连接到逻辑控制单元421，以从逻辑控制单元421获得门锁短接信号，该第一光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第一开关管Q1的控制端连接到第一光耦的副边。第一双触点继电器的线圈KM1-3、第一开关管Q1串联连接在上门区信号传感器或下门区信号传感器的输出端与参考地COM之间。类似地，第二开关控制回路包括第二光耦和第二开关管Q2，其中第二光耦的原边连接到逻辑控制单元421，以从逻辑控制单元421获得门锁短接信号，该第二光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第二开关管Q2的控制端连接到第二光耦的副边。第二双触点继电器的线圈KM2-3、第二开关管Q2串联连接在上门区信号传感器或下门区信号传感器的输出端与参考地COM之间。
由于第一开关控制回路和第二开关控制回路均由上门区信号传感器或下门区信号传感器的输出端供电，即第一光耦、第二光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第一双触点继电器的线圈KM1-3、第二双触点继电器的线圈KM2-3所在回路由上门区信号传感器或下门区信号传感器的输出端供电，从而可保证第一双触点继电器的主触点KM1-1和第二双触点继电器的主触点KM2-1仅在上门区信号传感器和下门区信号传感器位于隔磁板20所在区域（即门区）时才短接电梯门锁回路中的门锁开关，保证安全性。
如图5所示，本发明的电梯安全运行系统还可应用于双开门的电梯系统，即电梯系统的轿厢包括两个轿门，即门一（主门）和门二（副门），相应地，电梯门锁回路包括门一轿门锁开关GS、门一层门锁开关组DS、门二层门锁开关组RDS以及门二轿门锁开关RGS，且门一轿门锁开关GS的尾端连接到门一层门锁开关组DS的首端，门一层门锁开关组DS的尾端连接到门二层门锁开关组RDS的首端，门二层门锁开关组RDS的尾端连接到门二轿门锁开关RGS的首端。本实施例的电梯安全运行系统同样包括电梯主控制器51和安全功能装置52，且安全功能装置包括逻辑控制单元521、开关控制单元522、封门开关组523、用于连接门一轿门锁开关GS的首端的第三外接端子SO3、用于连接门一层门锁开关组GS的尾端的第四外接端子SO4、用于连接门二层门锁开关组RDS的尾端的第五外接端子SO5、用于连接门二轿门锁开关RGS的尾端的第六外接端子SO6。

逻辑控制单元521可由微控制单元并结合在其上运行的软件构成。该逻辑控制单元521连接到上门区信号传感器21和下门区信号传感器22的输出端，从而可实时获取上门区信号传感器21和下门区信号传感器22的输出信号。该逻辑控制单元521还与电梯主控制器51连接，以与电梯控制器51进行信息交互。具体地，逻辑控制单元521可在接收到来自电梯主控制器51的封门指令时，生成门锁短接信号，并将上述门锁短接信号发送到开关控制单元522，使开关控制单元522分别控制相应的接触器闭合，从而配合电梯主控制器51实现提前开门或再平层功能。
上述逻辑控制单元521还连接到所述第三双触点继电器、第四双触点继电器和第五双触点继电器的辅触点KM3-2、KM4-2、KM5-2，并根据上述辅触点KM3-2、KM4-2、KM5-2的状态向电梯主控制器30反馈第三双触点继电器、第四双触点继电器以及第五双触点继电器的主触点KM3-1、KM4-1、KM5-1的通断状态，使电梯主控制器51可根据上述状态执行相应操作，提高安全性。
具体地，第三开关控制回路包括第三光耦和第三开关管Q3，第三光耦的原边连接到逻辑控制单元521，并从逻辑控制单元521获得门锁短接信号，第三光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第三开关管Q3的控制端连接到第三光耦的副边。第三双触点继电器的线圈KM3-3、第三开关管Q3串联连接在上门区信号传感器或下门区信号传感器的输出端与参考地COM之间。类似地，第四开关控制回路包括第四光耦和第四开关管Q4，第四光耦的原边连接到逻辑控制单元521，并从逻辑控制单元521获得门锁短接信号，第四光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第四开关管Q4的控制端连接到第四光耦的副边。第四双触点继电器的线圈KM4-3、第四开关管Q4串联连接在上门区信号传感器或下门区信号传感器的输出端与参考地COM之间。第六开关控制回路包括第五光耦和第五开关管Q5，第五光耦的原边连接到逻辑控制单元521，并从逻辑控制单元521获得门锁短接信号，第五光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第五开关管Q5的控制端连接到第五光耦的副边。第五双触点继电器的线圈KM5-3、第五开关管Q5串联连接在上门区信号传感器或下门区信号传感器的输出端与参考地COM之间。

具体地，第七开关控制回路包括第六光耦和第六开关管Q6，第六光耦的原边连接到逻辑控制单元521，并从逻辑控制单元521获得门锁短接信号，第六光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第六开关管Q6的控制端连接到第六光耦的副边。第六双触点继电器的线圈KM6-3、第六开关管Q6串联连接在供电电源与参考地COM之间。类似地，第八开关控制回路包括第七光耦和第七开关管Q7，第七光耦的原边连接到逻辑控制单元521，并从逻辑控制单元521获得门锁短接信号，第七光耦的副边由上门区信号传感器或下门区信号传感器的输出端供电，且第七开关管Q7的控制端连接到第七光耦的副边。第七双触点继电器的线圈KM7-3、第七开关管Q7串联连接在供电电源与参考地COM之间。
