为了解决现有技术问题，本申请实施例提供了一种电梯故障诊断方法、装置、设备及计算机存储介质。下面首先对本申请实施例所提供的电梯故障诊断方法进行介绍。
为保证电梯能安全地运行，在电梯上装有许多***件。只有每个***件都正常的情况下，电梯才能运行，否则电梯立即停止运行。例如，安全回路，就是在电梯各***件都装有一个安全开关，把所有的安全开关串联，控制一个安全继电器。只有所有安全开关都在接通的情况下，安全继电器吸合，电梯才能得电运行。一般安全回路包括相序保护继电器、限速器、安全钳、紧急停车按钮、紧急出口开关、底坑开关、限位开关等 装置的触点和继电器。其中任意一个装置的继电器失电，电梯便无法行驶，即使是正在行驶的电梯也因此停止运行。又例如，门锁回路，就是在每扇厅门及轿门上都装有门电气联锁开关，把所有的门电气联锁开关串联，控制一个门锁继电器，以保证电梯必须在全部门关闭后才能运行。只有在门锁回路必须接通，即全部门电气联锁开关全部接通的情况下，门锁回路的门锁继电器方能吸合，电梯才能运行。门电气联锁开关是电梯中用量很大，安全系数很高的***件。只有轿厢所在楼层的层门可以被开启，其余层门不允许被开启。
当电梯安全回路被短接时，即安全回路短路时，如果电梯仍处于快车运行状态，电梯将发生危险。例如，当安全回路发生故障时，检修人员在维修过程中有时因工作需要而短接安全回路，当检修结束，一定要先取掉门锁短接线，方能将电梯恢复到快车状态。如果在维修时，没有事先打开检修开关就短接安全回路；或在检修结束后，忘记取掉安全短接线，或存在其他人为短接安全回路的情况下，则会导致电梯在短接安全回路的情况下，还以快车速度运行，这是非常危险的。或者，当门锁回路发生故障时，一般检修做法是确保在检修状态下，控制屏分开短接厅门锁和轿门锁，分出是厅门部分还是轿门部分的故障。确保检修状态下，短接厅门锁回路，以检修速度运行电梯。当检修结束，一定要先取掉门锁短接线，方能将电梯恢复到快车状态。如果在维修时，没有事先打开检修开关就短接门锁回路；或在检修结束后，忘记取掉门锁短接线；或存在其他人为短接门锁回路的情况下，则会导致电梯在短接门锁回路时，还以快车速度运行，这是非常危险的。
图1示出了本申请一个实施例提供的电梯故障诊断方法的流程示意图。如图1所示，本申请实施例的电梯故障诊断方法包括以下步骤：
S110，获取电梯回路中与电压信号相关的检测值；
S120，基于检测值与预设阈值的比较结果，判断电梯回路是否发生故障；
S130、若电梯回路发生故障，确定发生与电梯回路异常相关的电梯故障。
在本申请实施例中，基于电梯回路中与电压信号相关的检测值与预设阈值的比较，进而确定电梯回路是否发生故障。这里，电梯回路故障可以是电梯回路短路，或者电梯回路的电源直接被断掉。可以是将电压采集装置与电梯回路并联以获取电梯回路的与电压信号相关的检测值。根据本申请实施例，能够准确确定电梯回路是否发生故障，进而确定是否发生与电梯回路异常相关的电梯故障，从而将电梯安全事故防患于未然。
在一个实施方式中，电梯回路中与电压信号相关的检测信号包括门锁回路的电压信号。门锁回路的电压信号可以理解为门锁回路的实时电压值。获取门锁回路的电压信号，例如，可以是将电压采集装置与电梯门锁回路并联以获取门锁回路的电压信号。此时，电压采集装置可以是隔离变送器，隔离变送器能够将门锁回路的实际电压信号转换为在一定范围内的电压信号，转换后的电压信号与实际电压信号具有线性关系。
在本申请实施例中，由于获取的是转换后的门锁回路的电压信号，因此能够准确反应门锁回路的特性，即门锁回路的电压信号的变化情况。且电压采集装置与门锁回路是并联关系，对门锁回路本身没有任何影响，也不会因为电压采集装置自身的问题而影响门锁回路。
而若是采集门锁回路的电阻值进而判断门锁回路情况的话，采集的电阻值与门锁回路的实际电阻值不具备线性关系，且电阻采集装置会对门锁回路自身造成影响，不能够准确反应门锁回路的特性。
如图2、图3和图6所示，图2、图3和图6为采集的永春县某个电梯在正常情况下的信号数据，包括门锁回路的电压信号、此电梯的光电对信号和速度信号。线1表示门锁回路的电压信号变化情况，2表示光电对信号变化情况，3表示电梯速度信号变化情况，横轴单位为毫秒，竖轴单位为V。
在本申请实施例中，电梯所在建筑各楼层中的每一层平层处安装有挡片，在电梯轿厢的预设位置处安装光电传感器，这里预设位置可以是电梯轿厢顶部。当电梯通过楼层平层或者停在楼层平层时，挡片遮挡光电传感器，此时，光电传感器检测的光电信号值为1V。而挡片未遮挡光电传感器时，光电传感器检测的光电信号值为0。
在本申请实施例中，当电梯处于移动状态时，若门锁回路的电压值小于预设阈值，确定门锁回路发生短路或者门锁回路的电源直接被断掉，这里，门锁回路的电源直接被断掉可以理解为整个电梯的电源被断掉。当电梯处于静止状态时，若门锁回路的电压值小于预设阈值且电梯处于静止状态的静止时长大于预设第一时长时，确定门锁回路发生短路。其中，预设阈值为第一电压阈值。
这里，门锁回路的电压信号可以表征电梯的开关门信号。正常情况下，当电梯处于移动状态时，即电梯移动速度不为0时，电梯门处于关闭状态，门锁回路的电压为高电压，所谓高电压可以理解为不低于第一电压阈值的电压。这里，电梯处于移动状态可以是电梯处于水平移动状态或者垂直移动状态。当电梯处于静止状态时，即电梯的移动速度为0时，电梯门进行开关门的动作，此时门锁回路的电压信号发生变化，由高电压变为低电压，再由低电压变为高电压，当门锁回路的电压信号变回高电压后，电梯由静止状态变为移动状态。所谓低电压，可以是小于第一电压阈值且非常接近于0的电压，例如，第一电压阈值为0.2V。
如图4和图5所示，图4和图5为采集的泉州市某个电梯在异常情况下的信号数据，包括门锁回路的电压信号、此电梯的光电对信号和速度信号。线1表示门锁回路的电压信号变化情况，2表示光电对信号变化情况，3表示电梯速度信号变化情况，横轴单位为毫秒，竖轴单位为V。
在本申请实施例中，结合电梯运行状态及电梯门锁回路的电压信号判断门锁回路的情况。例如，当电梯运行状态为移动状态时，即电梯移动速度不为0时，若门锁回路的电压信号小于第一电压阈值，则电梯门锁回路短路。当电梯为静止状态时，即电梯的移动速度为0时，若门锁回路的电压信号小于第一电压阈值，且电梯处于静止状态的静止时长大于第一预设时长时，则电梯门锁回路短路或者门锁回路的电源直接被断掉，这里，门锁回路的电源直接被断掉可以理解为整个电梯的电源被断掉。例如，第一预设时长为10秒。
正常情况下，电梯为静止状态或者光电信号为1V时，门锁回路的电压信号会出现高-低-高的变化，即，电梯门被正常的开和关。如图4或图5 所示，电梯为移动状态或者光电信号为0V时，或者，电梯为静止状态的时长超过第一预设时长，而门锁回路的电压信号是小于第一电压阈值的，则说明门锁回路短路或者门锁回路的电源直接被断掉，这里，门锁回路的电源直接被断掉可以理解为整个电梯的电源被断掉，即电梯回路出现异常。
根据本申请实施例，能够准确确定门锁回路是否发生短路或者门锁回路的电源直接被断掉，这里，门锁回路的电源直接被断掉可以理解为整个电梯的电源被断掉，进而确定是否发生与门锁回路异常相关的电梯故障，从而将电梯安全事故防患于未然。
作为一个示例，可以根据电梯运行过程中门锁回路的电压值及电梯所处的状态，判断电梯是否发生与电梯运行相关的电梯故障。
例如，在电梯运行过程中，当电梯所处的状态至少连续发生两次由移动状态向静止状态的切换时，若门锁回路的电压值始终保持不变，确定电梯发生与电梯运行相关的电梯故障。这里可以理解为，当电梯运行状态为至少两次由移动状态至静止状态的循环时，若门锁回路的电压信号未出现变化，确定电梯不属于安全运行状态。如上文所述，门锁回路的电压信号可以表征电梯的开关门信号，若门锁回路的电压信号未出现变化，则表示电梯门没有开关门的动作，此时，可能存在开门走梯的情况，即电梯开着门移动，是非常不安全的运行状态。至少两次由移动状态至静止状态的循环可以理解为，电梯的运行状态为“移动-静止-移动-静止”或者“移动-静止-移动-静止-移动-静止”。
这里，至少两次循环是为了防止出现误判，因为大部分电梯都具备自动归位的功能，即电梯在一定时长后无乘客使用时，自动由当前楼层回归到预设楼层，此时，电梯门是不需要开关门动作的，即门锁回路的电压信号是不会出现变化的。
又例如，当电梯所处的状态由移动状态切换至静止状态，且电梯处于静止状态的静止时长大于预设第二时长时，若门锁回路的电压值始终保持不变，确定电梯内是否有乘客。若电梯内有乘客，确定电梯发生与电梯运行相关的电梯故障。这里可以理解为，当电梯运行状态为移动状态至静止状态，且静止时长大于第二预设时长时，若门锁回路的电压信号未出现变 化，则说明电梯门一直处于关闭状态。进一步判断电梯内是否有乘客，若电梯内有乘客，则说明存在电梯关人的情况，这是非常不安全的运行状态。这里，可以利用红外传感器判断电梯内是否有乘客，或者利用图像采集装置获取电梯内部的采集图像，根据获取的采集图像判断电梯内是否有乘客。若电梯内有乘客，立即进行报警，通知相关工作人员进行施救和维修。
在本申请实施例中，能够及时发现电梯是否存在开门走梯或者电梯关人的情况，将电梯的重大安全事故防患于未然。
在另一个实施方式中，与电压信号相关的检测信号包括安全回路的电压值。若安全回路的电压值小于预设阈值，确定安全回路发生短路或者安全回路的电源直接被断掉，这里，安全回路的电源直接被断掉可以理解为整个电梯的电源被断掉。其中，预设阈值为第二电压阈值。
这里可以理解为，电梯回路中与电压相关的检测信号包括安全回路的电压信号。安全回路的电压信号可以理解为安全回路的实时电压值。获取安全回路的电压信号，例如，可以是将电压采集装置与电梯安全回路并联以获取安全回路的电压信号。此时，电压采集装置可以是隔离变送器，隔离变送器能够将安全回路的实际电压信号转换为在一定范围内的电压信号，转换后的电压信号与实际电压信号具有线性关系。
在本申请实施例中，获取的是转换后的安全回路的电压信号，能够准确反应安全回路的特性，即安全回路的电压信号的变化情况。且电压采集装置与安全回路是并联关系，对安全回路本身没有任何影响，也不会因为电压采集装置自身的问题而影响安全回路。
而若是采集安全回路的电阻值进而判断安全回路情况的话，采集的电阻值与安全回路的实际电阻值不具备线性关系，且电阻采集装置会对安全回路自身造成影响，不能够准确反应安全回路的特性。
如图7所示，正常情况下，无论电梯是移动状态还是静止状态，安全回路的电压信号应该始终为高电压状态，所谓高电压可以理解为不低于第二预设阈值的电压。若安全回路的电压信号小于第二电压阈值，确定电压回路出现短路或者安全回路的电源直接被断掉，这里，安全回路的电源直接被断掉可以理解为整个电梯的电源被断掉。例如，第二电压阈值为0.2V。
根据本申请实施例，能够准确确定安全回路是否发生短路或者安全回路的电源直接被断掉，这里，安全回路的电源直接被断掉可以理解为整个电梯的电源被断掉，进而确定是否发生与安全回路异常相关的电梯故障，从而将电梯安全事故防患于未然。
由于本申请实施例的电梯回路包括安全回路和门锁回路，因此，当检测到安全回路和门锁回路中任一个发生短路或者回路的电源直接被断掉时，这里，回路的电源直接被断掉可以理解为整个电梯的电源被断掉，即确定电梯回路发生短路或者电梯回路的电源直接被断掉，从而确定发生与电梯回路异常相关的电梯故障。
在又一个实施方式中，与电压信号相关的检测信号包括在电梯回路的信号输出点采集的输出信号，其中，输出信号为由电梯回路的信号输入点耦合至电梯回路中的具有预设频率的耦合信号扩散至信号输出点的信号。若输出信号的电压幅值小于预设阈值，确定电梯回路发生短路或者电梯回路的电源直接被断掉，这里，电梯回路的电源直接被断掉可以理解为整个电梯的电源被断掉，其中，预设阈值为所述耦合信号的电压幅值。
这里可以理解为，电梯回路中与电压相关的检测信号包括电梯回路中的输出点输出的耦合信号，耦合信号包括利用信号耦合装置将预设频率的初始电压信号在输入点耦合至电梯回路中并沿着电梯回路扩散至输出点并经接收器输出的信号，其中，初始电压信号包括可编程逻辑控制器(Programmable Logic Controller，PLC)信号，这里初始电压信号不仅可以是PLC信号，也可以是具有预设频率的其他信号，例如，预设频率为50Hz。初始电压信号为小信号，所谓小信号可以理解为小于预设阈值的信号，且预设阈值小于电梯回路的电压信号。例如，正常情况下电梯回路的电压值为5V的话，初始电压信号的值可以为2V。另外，对输入点和输出点在电梯回路上的具***置不作限定。
在本申请实施例中，将耦合信号与预设阈值进行比较，这里预设阈值为初始电压信号，若耦合信号的幅值小于初始电压信号的幅值，即耦合信号出现幅值衰减，确定电梯回路短路或者电梯回路的电源直接被断掉，这里，电梯回路的电源直接被断掉可以理解为整个电梯的电源被断掉。
耦合信号包括利用信号耦合装置分别将预设频率的初始电压信号在输入点耦合至门锁回路和安全回路中，并沿着门锁回路和安全回路扩散至输出点并经接收器输出的信号。即，分别检测门锁回路和安全回路的耦合信号，若门锁回路和安全回路中任一耦合信号出现幅值衰减，确定电梯回路短路或者电梯回路的电源直接被断掉，这里，电梯回路的电源直接被断掉可以理解为整个电梯的电源被断掉。
在本申请实施例中，利用信号耦合法判断电梯回路情况，不会对电梯回路本身造成任何影响，能够准确反应电梯回路的特性。
进一步，若门锁回路和安全回路任意一项出现短路或者电源被断掉，或者电梯开着门的情况下移动，或者电梯静止状态下关人，即电梯门静止状态下打不开，都可以进行报警提示，及时将报警信息上传至云服务平台，以提醒相关人员进行维修或者施救被关闭在电梯内的乘客。
