具体实施方式
下面详细描述本公开的实施例，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，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例提出的电梯控制方法、电梯控制装置、电梯控制器、计算机可读存储介质、计算机程序、计算机程序产品、电梯安全系统和电梯。
图1为根据本公开实施例的电梯控制方法的流程图。
如图1所示，本公开实施例的电梯控制方法，可包括：
S1，确定故障楼层，并根据故障楼层确定安全区域；
S2，在轿厢位置处于安全区域内时，根据轿厢位置、目标楼层以及安全区域确定目标停靠楼层，以根据目标停靠楼层执行救援操作，其中，目标楼层为用户选择楼层。
具体地，故障楼层用于限定无法满足电梯正常运行需求的楼层，例如，厅门无法正常 打开、关闭的楼层等。例如，在每个楼层分别进行检测单元的布置，根据检测单元的反馈信号确定相应楼层是否发生故障，从而确定故障楼层。检测单元可采用传感器、摄像头、接触开关等方式，此处不作限制。
基于故障楼层划分安全区域和非安全区域，当轿厢位置处于安全区域内时，认为电梯运行的安全系数较高，可以控制电梯继续运行，以控制轿厢停靠相应楼层，并控制轿厢门和相应楼层的厅门开启，使用户尽快撤离出轿厢。当轿厢位置处于非安全区域时，则认为电梯继续运行会存在较大的安全隐患，控制电梯紧急停止运行。
以电梯服务范围为1-10楼，故障楼层为5楼为例，基于5楼的上下一个楼层之间都认为是不安全的，则4-6楼为非安全区域，1-3楼以及5-10楼认为是安全区域。假设轿厢位置处于2楼，轿厢位置处于安全区域，则按照电梯实际运行方向，控制轿厢停靠在最接近的楼层位置，例如，若电梯运行方向为向上运行，可以控制轿厢运行至3楼停止，然后控制轿厢门和3楼的厅门开启，使用户及时离开。
为提升用户乘坐体验，在存在故障楼层，且轿厢位置处于安全区域内的情况下，根据轿厢位置、目标楼层以及安全区域确定目标停靠楼层，该目标停靠楼层为进行救援操作的停靠楼层，在保证乘客尽快离开电梯轿厢的前提下，保证目标停靠楼层位于安全区域，提高救援安全，同时与目标楼层相结合，可以使目标停靠楼层尽量靠近目标楼层，以减少用户从轿厢离开后前往目标楼层所需的爬楼梯距离。
在本公开的一个实施例，各楼层设有厅门锁，确定故障楼层，包括：获取发生故障的厅门锁位置；根据厅门锁位置确定故障楼层。
也就是说，根据各楼层对应设置的厅门锁的状态进行故障楼层确定。
具体地，如图2所示，对一个每个楼层设置有相应的厅门锁(K_1、K_2……K_n-1、K_n)对相应楼层的厅门状态进行监测，其中，在相应楼层的厅门关闭时，厅门锁处于闭合状态；在厅门打开时，厅门锁处于断开状态。通过厅门装置61对厅门锁的状态进行监测，其中，厅门安全装置61的数量可根据楼层数配置，在图2中每六个楼层配置一个厅门安全装置61，通过一个厅门安全装置61对六个楼层的厅门锁进行状态监测。
以最靠近底坑位置的厅门安全装置61为例，第一楼层的厅门锁K_1、第二楼层的厅门锁K_2、第三楼层的厅门锁K_3、第四楼层的厅门锁K_4、第五楼层的厅门锁K_5和第六楼层的厅门锁K_6的一端均连接至厅门安全装置61的PWR引脚，该PWR引脚用于供电，另一端分别连接至厅门安全装置61的In6、In5、In4、In3、In2、In1引脚，厅门安全装置61可以根据各引脚的接收电平，确定各楼层的厅门锁状态。例如，在In1引脚为高电平时，确定第六楼层的厅门锁K_6处于闭合状态，若基于电梯控制确定当时控制第六楼层的厅门打开，则认为厅门锁K_6发生故障，若基于电梯控制确定未控制第六楼层的厅门打开，则认为厅门锁K_6未发生故障；在In1引脚为高电平时，确定第六楼层的厅门锁K_6处于断开状态，若基于电梯控制确定当时控制第六楼层的厅门打开，则认为厅门锁K_6未发生故障；若基于电梯控制确定未控制第六楼层的厅门打开，则认为厅门锁K_6发生故障。由此，在确定厅门锁K_6发生故障的情况下，基于厅门锁K_6的安装位置，确定将第六楼层为故 障楼层。
在本公开的一个实施例中，根据故障楼层确定安全区域，包括：获取电梯的运行速度和制动能力；根据运行速度和制动能力确定目标安全距离；基于目标安全距离和故障楼层，确定安全区域。
当电梯轿厢处于安全区域内时，若按照预设制动力对电梯进行制动控制，则电梯轿厢的停止位置与故障楼层之间的距离满足安全要求，运行安全性较高。当电梯轿厢处于非安全区域时，若按照预设制动力对电梯进行制动控制，则可能出现电梯轿厢的停止位置靠近故障楼层，或者制动过程中电梯轿厢经过故障楼层，安全性较低。因此，为提升电梯运行安全，该实施例基于电梯的制动能力和运行速度对安全区域进行动态调整。
具体地，为保证电梯的安全运行，电梯安全系统通过制动检测单元对电梯的制动能力进行周期性监测，其中，制动能力可通过制动距离、制动力等参数进行确定。在电梯控制过程中，制动能力可以直接从电梯安全系统内调用，并基于速度传感器确定电梯的运行速度。可以理解的是，在相同运行速度下，制动能力越强，所需的制动距离越短；制动能力越弱，所需的制动距离越长。在相同制动能力下，运行速度越快，所需制动距离越长；运行速度越慢，所需制动距离越短。
在确定电梯的制动能力与运行速度之后，根据制动能力和运行速度确定实际制动距离，基于实际制动距离确定目标安全距离，进一步结合故障楼层的位置进行安全区域的确定。例如，假设实际制动距离为1m，可确定目标安全距离为1.5m，假设故障楼层的高度为10m，那么安全区域为8.5m以下、11.5m以上。
在本公开的一个实施例中，根据运行速度和制动能力确定目标安全距离，包括：根据运行速度和制动能力确定距离调节参数；基于距离调节参数对预设安全距离进行调整，得到目标安全距离。
具体地，除上述基于运行速度和制动能力确定实际制动距离，基于实际制动距离确定目标安全距离之外，也可以预先保存预设安全距离，根据实时确定的运行速度和制动能力确定距离调节参数，距离调节参数可以为比例系数、距离值。例如，可基于试验预先建立运行速度、制动能力与距离调节参数的关系表，在控制过程中基于确定的运行速度和制动能力查表得到距离调节参数，进而通过距离调节参数对预设安全距离进行调整，以调整后的预设安全距离作为目标安全距离。
该方法基于电梯的运行速度和制动能力，自动修正电梯的目标安全距离，提高可控制可靠性，保证乘坐安全。
在本公开的一个实施例中，根据故障楼层确定安全区域，包括：基于故障楼层和预设安全距离，确定安全区域。也就是说，在电梯控制过程中以固定的预设安全距离进行安全区域的确定。
在本公开的一个实施例中，根据轿厢位置、目标楼层以及安全区域确定目标停靠楼层，包括：在目标楼层处于安全区域内时，基于轿厢位置与目标楼层的位置关系确定目标停靠楼层；在目标楼层处于安全区域外时，根据轿厢位置和安全区域确定目标停靠楼层。
具体地，以电梯服务楼层为1-20楼，故障楼层为10楼，则安全区域为1-8楼和12-20楼为例。若轿厢位置处于安全区域，且用户选择的目标楼层也处于安全区域内，则根据轿厢位置和目标楼层确定目标停靠楼层，以进行电梯救援控制。若轿厢位置处于安全区域，且用户选择的目标楼层处于安全区域外即非安全区域，则根据轿厢位置和安全区域确定目标停靠楼层，以保证救援操作的安全性。
在本公开的一个实施例中，基于轿厢位置与目标楼层的位置关系确定目标停靠楼层，包括：在轿厢位置和目标楼层处于故障楼层的同一侧时，将目标楼层作为目标停靠楼层；在轿厢位置和目标楼层处于故障楼层的两侧时，根据轿厢位置和安全区域确定目标停靠楼层。
具体地，继续以电梯服务楼层为1-20楼，故障楼层为10楼，则安全区域为1-8楼和12-20楼为例。
如果当前轿厢位置处于2楼，目标楼层为6楼，则直接以6楼作为目标楼层，即控制电梯运行至6楼停靠，然后控制轿厢门和6楼厅门打开，使用户及时离开电梯轿厢。该实施例在完成对用户救援操作的前提下，也满足了用户的出行需求。
如果当前轿厢位置处于2楼，目标楼层为15楼，那么运行至目标楼层就会经过故障楼层，存在安全风险，因此根据轿厢位置和安全区域确定目标停靠楼层，例如确定目标停靠楼层为3楼。在控制电梯保持当前运行方向的前提下，使得目标停靠楼层处于安全区域内，以保证乘坐安全。
在本公开的一个实施例中，电梯控制方法还包括：在轿厢位置处于安全区域外时，控制电梯急停，并根据轿厢位置和安全区域确定目标停靠楼层，以根据目标停靠楼层执行在电梯急停后的救援操作。
具体地，继续以电梯服务楼层为1-20楼，故障楼层为10楼，则安全区域为1-8楼和12-20楼为例。
如果当前轿厢位置处于9楼，此时，若控制电梯继续运行或者按照预设制动力进行制动，可能会出现电梯轿厢停靠在故障楼层10楼，甚至电梯轿厢穿过故障楼层的情况，具有较大的安全风险。因此，在确定当前轿厢位置处于安全区域外时，控制电梯急停，在电梯急停后再进行救援操作。
在本公开的一个实施例中，根据轿厢位置和安全区域确定目标停靠楼层，包括：根据轿厢位置和安全区域确定安全区域极限位置，并将最接近安全区域极限位置且处于安全区域内的楼层作为目标停靠楼层，且轿厢位置至目标停靠楼层之间不包括故障楼层。
具体地，继续以电梯服务楼层为1-20楼，故障楼层为10楼，则安全区域为1-8楼和12-20楼为例。
如果当前轿厢位置处于2楼，目标楼层为15楼，则以8楼作为目标停靠楼层。如果当前轿厢位置处于9楼，那么在控制电梯急停后，以8楼作为目标停靠楼层。如果当前轿厢位置处于10楼，那么轿厢位置距离两个安全区域的距离相等，这个情况下可以根据急停前的电梯运行方向进行确定，例如，假设在电梯急停控制前电梯向上运行，则选择12作为目 标停靠楼层。
在本公开的一个实施例中，电梯控制方法还包括：根据安全区域对电梯的预设服务楼层区间进行调整。
也就是说，假设电梯的预设服务楼层区间为1-20楼，在确定10楼为故障楼层，安全区域为1-8楼和12-20楼的情况下，可将电梯的预设服务楼层区间调整为1-8楼，使得电梯可以在安全区域内正常运行。
作为本申请的一个具体实施例，如图3所示，该电梯控制方法可包括以下步骤：
S301，获取厅门锁的状态信息。
S302，判断是否有厅门锁发生故障。若是，执行步骤S303；若否，执行步骤S301。
S303，获取发生故障的厅门锁位置。
S304，根据厅门锁位置确定故障楼层。
S305，获取电梯的运行速度和制动能力。
S306，根据运行速度和制动能力查表确定距离调节参数k。
S307，计算目标安全距离S＝k*S0。其中，S0为预设安全距离。
S308，根据目标安全距离S和故障楼层确定安全区域。
S309，判断轿厢位置是否处于安全区域内。若是，执行步骤S310；若否，执行步骤S316。
S310，判断目标楼层是否处于安全区域内。若是，执行步骤S311；若否，执行步骤S312。
S311，判断轿厢位置和目标楼层是否处于故障楼层的同一侧。若是，执行步骤S312；若否，执行步骤S314。
S312，将目标楼层作为目标停靠楼层。
S313，根据目标停靠楼层执行救援操作。
S314，根据轿厢位置和安全区域确定安全区域极限位置。
S315，将最接近安全区域极限位置且处于安全区域内的楼层作为目标停靠楼层，且轿厢位置至目标停靠楼层之间不包括故障楼层。执行步骤S313。
S316，控制电梯急停。执行步骤S314。
除了通过厅门锁确定故障楼层外，在底坑或机房处的电气安全开关发生故障时，也可以以底坑、机房作为故障楼层，进而确定安全区域，以执行救援运行。例如，轿厢位置为10楼，位于底坑的轿厢缓冲器开关故障，此时可以结合电梯的运行方向和轿厢位置执行就近平层救援，以防止电梯急停故障困人，同时可根据实际情况对电梯运行速度进行降速，以相对低的速度停靠在目标停靠楼层，保证电梯运行的安全性。
综上，根据本公开实施例的电梯控制方法，首先确定故障楼层，并根据故障楼层确定安全区域，并在轿厢位置处于安全区域内时，根据轿厢位置、目标楼层以及安全区域确定目标停靠楼层，以根据目标停靠楼层执行救援操作，其中，目标楼层为用户选择楼层。由此，该方法在出现故障楼层，且轿厢位置处于安全区域内的情况下，结合轿厢位置、目标楼层以及安全区域执行救援操作，可在保证安全的前提下及时完成乘客救援，避免乘客长时间被困电梯轿厢内的情况发生，提升乘客的乘坐体验。

如图6所示，本公开实施例的电梯安全系统，该电梯安全系统包括：安全回路50、安全装置60、轿厢位置检测装置70和上述的电梯控制器80。
其中，安全回路50包括若干电气安全开关51。安全装置60用于检测电气安全开关51的工作状态，并生成相应的状态检测信号。轿厢位置检测装置70用于检测电梯的轿厢位置。电梯控制器80与安全装置60和轿厢位置检测装置70相连，电梯控制器80用于根据状态检测信号确定故障楼层，并根据故障楼层确定安全区域，以及在轿厢位置处于安全区域内时，根据轿厢位置、目标楼层和安全区域确定目标停靠楼层，以基于目标停靠楼层执行救援操作，其中，目标楼层为用户选择楼层。
具体地，下面结合图2、图6至图9对该实施例的电梯安全系统进行举例说明。
在电梯安全系统中布置有多个电气安全开关51，电梯安全系统基于电气安全开关的状 态检测，实现对电梯的安全监测以及控制。
在相关技术中，采用将电梯中的所有电气安全开关依次串联的形式来构成安全回路，以控制电梯的驱动主机的供电电源和制动器的电源。由于电气安全开关分别放置在机房、井道、厅门、轿顶、底坑的位置，因此整个电梯的安全回路的线路非常长，以电梯提升高度为100米为例，安全回路的线路将达到1000米甚至更长。安全回路的电源电压通常采用交流220Vac或者有变压器产生的110Vac,较长的安全回路会带来回路干扰、回路压降、回路线径、门锁触点老化造成回路电阻过大等问题，另外，在电梯长期使用的情况下，电梯产品老化，也会使安全回路处在不稳定状态，进一步降低了电梯的安全性能。
在本申请实施例的电梯安全系统中，安全装置60包括厅门安全装置61、底坑安全装置62、轿顶安全装置63和机房安全装置64，厅门安全装置61的数量可根据电梯运行的楼层数量进行配置，例如在电梯的服务楼层为20层时，可设置4个厅门安全装置61每个厅门安全装置61负责检测五个楼层的厅门锁。电气安全开关51根据电气安全开关51的安装位置，就近连接至厅门安全装置61、底坑安全装置62、轿顶安全装置63、机房安全装置64，且各个电气安全开关51通过I/O方式接入相应安全装置60，以进行开关状态监控。结合可编程电子系统，厅门安全装置61、底坑安全装置62、轿顶安全装置63通过总线(例如CAN/485等安全总线)将监测到的电气安全开关51的状态发送到机房安全装置64，至此整个电梯的电气安全开关51的状态汇总到机房安全装置64。机房安全装置64结合电梯控制器80的运行指令，通过引脚Control对安全继电器K1、K2进行接通处理，以控制电梯的驱动主机的供电电源和制动器的电源。由此，该实施例简化了安全回路50的物理连接的复杂性，缩短了安全回路50的路径，同步降低了过长的线路阻抗问题，以及电网电压波动对回路阻抗引起的阻抗波动问题。
可以理解的是每个安全装置60都设置有用于检测电气安全开关51的开关状态的状态检测电路以及控制模块。为提高状态检测精度，可在每个状态检测电路中进行多个检测单元的布置，通过多个检测单元对一个电气安全开关51的状态进行检测并分别输出检测反馈信号，相应安全装置60内的控制模块根据多个检测反馈信号来判断该电气安全开关51的当前状态，以提高检测精度。例如，可以在同一个电气安全开关51的多个检测反馈信号相同的情况下，根据检测反馈信号确定该电气安全开关51的当前状态；在同一电气安全开关51的多个检测反馈信号不相同的情况下，直接认为该电气安全开关51故障，也可以反馈检测故障信号。
举例来说，对厅门锁K_1的状态检测电路如图9所示，厅门安全装置61的PWR引脚用于提供电源VCC，厅门锁K_1的一端通过PWR引脚与电源VCC相连，另一端连接至In6引脚以接入状态检测电路。该状态检测电路包括两个检测单元，每个检测单元电路相同，每个检测单元电路分别由电阻R1、电阻R2、稳压二极管D1、比较器A1和隔离光耦U1组成，其中，隔离光耦U1的输出端用于输出检测反馈信号。
该实施例采用电压比较电路进行厅门锁K_1的状态监控，当厅门锁K_1处于闭合阶段，通过厅门锁K_1和电阻R1对VCC分压，并输出第一分压电压至比较器A1的正输入端， 基于电阻R2和稳压二极管D1输出电压Vref至比较器A2的负输入端，在比较器A1的正输入端的电压大于比较器A2的负输入端的电压的情况下，比较器A1输出高电平，以驱动隔离光耦U1动作，隔离光耦U1输出高电平的检测反馈信号。
需要说明的是，图9中各电气元件的参数可根据实际情况进行选择，以保证在厅门锁K_1闭合的情况下，比较器A1均输出高电平，以驱动隔离光耦U1动作，输出高电平的检测反馈信号。此时，只有在厅门锁K_1断开的情况下，比较器A1才会输出低电平，检测反馈信号为低电平，以判定厅门锁K_1处于断开状态。该电路大大降低了电梯安全系统对厅门锁触点的要求，提升了电梯电控系统对环境的适应能力，避免了相关技术中因厅门锁的触点电阻过大造成状态检测错误的情况发生。
厅门安全装置61的控制模块根据接收的两个检测反馈信号来判断厅门锁K_1的当前状态。例如，在两个检测单元的检测反馈信号均为高电平的情况下，认为厅门锁K_1处于闭合状态；在两个检测单元的检测反馈信号均为低电平的情况下，认为厅门锁K_1处于断开状态；在两个检测单元的检测反馈信号一个为高电平、一个为低电平的情况下，由于无法确定厅门锁K_1的当前状态，则直接认为厅门锁K_1故障，或者也可以反馈检测故障信号。
可以理解的是，图9也可以用于其他电气安全开关51的状态监测。例如，底坑安全装置62对应的缓冲器电气安全开关、极限开关、辅助急停开关、底坑门开关、底坑爬梯开关、限速器张紧装置开关、绝对值位置磁条张紧装置开关、底坑平台开关等；轿顶安全装置63对应的安全钳电气安全开关、极限开关、轿顶急停开关、辅助急停开关、安全窗开关、轿厢锁定开关等；机房安全装置64对应的限速器电气安全开关、极限开关、控制柜急停开关、辅助急停开关、盘车手轮开关、夹绳器开关、曳引机防护罩开关等。
进一步需要说明的是，底坑安全装置62、轿顶安全装置63、机房安全装置64的电气安全开关51可以参照厅门锁的布置方式，即如图7和图8所示的一一对应监测，即通过In引脚对每个电气安全开关51进行状态检测；也可以根据是否被紧急电动开关旁路对电气安全开关进行分组，如图2所示，将可以被紧急电动旁路的电气安全开关进行串联，将不可以被紧急电动旁路的电气安全开关进行串联，相应安全装置的PWR引脚和In引脚分别连接串联支路的两端，以进行电气安全开关的状态检测。
当电梯正常运行启动时，各个安全模块60对相应的电气安全开关51的状态进行监测，并通过安全总线将各个电气安全开关51的状态传输到机房安全装置64，机房安全装置64得到所有的电气安全开关51的工作状态，并在确定所有电气安全开关51均处于闭合状态的情况下确定安全回路50状态正常，并通过通讯将安全回路50的状态传输给电梯控制器80，电梯控制器80发起启动指令给机房安全模块64，机房安全模块64闭合输出安全继电器K1、K2。其中，安全继电器K1、K2作为控制主接触器，以控制曳引机电源和抱闸电源。在电梯正常运行过程中，如果发生电气安全开关51断开，通过安全总线立刻将电气安全开关51的断开状态传输至机房安全装置64，机房安全装置64立刻断开输出安全继电器的电源，达到安全切断曳引机电源和抱闸电源安全控制，满足电梯标准的安全设计要求。
另外，该电梯安全系统还可以通过操作机房安全装置64连接的层门旁路装置、轿门旁 路装置对相应的厅门锁、电梯轿厢的轿门锁进行旁路。具体地，由于厅门锁是独立监控的，因此维保人员在操作厅门锁旁路装置时，可以针对性的旁路有问题的厅门锁，此时其他完好的厅门锁仍处于被监测状态，如在运行过程中发生突然断开，可以使电梯安全停车。相应的，由于轿门锁是独立监控的，因此维保人员在操作轿门锁旁路时，也可以针对性的旁路有问题的轿门锁。
在对位于机房、底坑、轿顶的各个电气安全开关51进行独立监控的实施例(如图7、图8)中，当紧急电动运行时，可以对电气安全开关51进行针对性的旁路，例如在测试操作过程中可以针对性的旁路被测试的电气安全开关51，使其他电气安全开关51仍处于监测状态，提升了操作安全性。另外，轿厢位置检测装置70采用绝对值安全井道位置传感器对轿厢位置进行实时监控，提升了监测精度。
在图8所示的实施例中，电梯安全系统作用于电梯群控系统，电梯安全系统基于目的层选层系统90可以将有故障的厅门锁排除在相应楼梯的服务楼层以外，使得电梯可以继续服务客户。例如，在该系统中包括电梯A和电梯B，假设电梯A的29楼的厅门锁故障，那么将29楼排除在电梯A的服务楼层范围以外。
根据本公开实施例的电梯安全系统，安全回路包括若干电气安全开关，通过安全装置检测电气安全开关的工作状态，并生成相应的状态检测信号，通过轿厢位置检测装置检测电梯的轿厢位置，电梯控制器可根据状态检测信号确定故障楼层，并根据故障楼层确定安全区域，以及在轿厢位置处于安全区域内时，根据轿厢位置、目标楼层和安全区域确定目标停靠楼层，以基于目标停靠楼层执行救援操作，其中，目标楼层为用户选择楼层。由此，该电梯安全系统在出现故障楼层，且轿厢位置处于安全区域内的情况下，结合轿厢位置、目标楼层以及安全区域执行救援操作，可在保证安全的前提下及时完成乘客救援，避免乘客长时间被困电梯轿厢内的情况发生，提升乘客的乘坐体验，另外电梯安全系统也可以将故障同步上报至运维中心，缩短维保的响应时间。
