技术领域
本发明涉及车辆车门紧急解锁技术领域，更具体地说，涉及一种车门紧急解锁控制方法，本发明还涉及一种车门系统。
背景技术
紧急出口装置属于轨道交通车辆车门系统的必要部件，用于在运营方允许的紧急情况下(如车辆故障失电等)手动解锁车门，保证车门此时仍能作为车内人员的逃生出口的一种装置。
一般情况下紧急出口装置主要由保护盖板、操作手柄、壳体以及钢丝绳轮组成，通过螺栓安装在车门附近的内饰部件上，处于乘客可视界面上。乘客可在紧急情况下打开保护盖板，按照指示操作手柄，通过与其连接的钢丝绳组件拉动车门承载驱动机构上的解锁装置，实现车门的机械解锁，从而为手动开门提供了可能。
手动解锁后，会触发车门的紧急解锁开关和锁到位开关，这些开关的触发将会为车辆提供必要的信息。
一般情况下，紧急出口装置的解锁控制方法如下：
a)操作紧急出口装置后，激活承载驱动机构上的紧急解锁开关，同时解除车门的锁闭状态，由车门控制单元通过车辆网络总线向车辆控制单元发送车 门紧急解锁信号，断开车门安全回路。
b)若车辆在零速时操作紧急出口装置，乘客可以手动打开车门。
c)若车辆在非零速时操作紧急解锁装置，车门被解锁，产生以下情况；
●车门控制单元将在关闭方向上启动车门驱动电机；
●若车门重新关锁到位，则电机停在当前位置；
●若车门未能关锁到位，电机将试图驱动车门回到关锁到位位置附近；此时若人为强行手动打开车门，则开门力不小于300N，以防止车门被乘客拉开。

具体实施方式
本发明实施例公开了一种车门紧急解锁控制方法，提高了车门是否可以手动打开的安全性，从而更好地保证乘客的安全疏散。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开的车门紧急解锁控制方法，包括以下步骤：
S11、打开紧急出口装置的保护盖板7或者在打开所述保护盖板7后，以不能解锁车门的小角度操作紧急出口装置的手柄9；
S12、若车辆处于故障失电情况，则紧急出口装置的手柄9被手柄控制结 构释放，允许所述手柄9操作；若车辆没有处于故障失电情况，即在车辆得电情况下，则进入步骤S13；
S13、激活车辆车门疏散请求回路，由所述车辆车门疏散请求回路向列车信号系统发送疏散请求信号；
S14、所述列车信号系统接收所述疏散请求信号后，控制车辆停止在安全的区域内，以激活零速车辆线信号(即由低电平变为高电平)，并控制车门禁止解锁车辆线信号无效(即由高电平变为低电平)，进而控制所述手柄9被手柄控制结构释放，允许所述手柄9操作。
本发明通过打开保护盖板7或者小角度操作手柄9，并在车辆处于非零速状态时，激活车辆车门疏散请求回路，向列车信号系统发送疏散请求信号；利用列车信号系统控制车辆停止在安全的区域内，以激活零速车辆线信号，并控制车门禁止解锁车辆线信号无效，进而控制手柄9被手柄控制结构释放，允许手柄9操作；实现了在列车信号系统控车情况下，与列车信号系统的交互，从而更好的保证乘客安全的疏散。
综上所述，本发明提供的车门紧急解锁控制方法在保护盖板7打开或手柄9小角度操作后能激活车辆车门疏散请求回路，主动发出疏散请求信号，后续的手柄9是否允许操作由信号系统决定，能与列车信号系统进行交互，将安全风险由车门级别提高到整个车辆运营系统，从而有利于从更高级别进行风险防范和应对，强化了车辆及车门本身对紧急出口装置控制的安全风险防范能力，所以提高了车门是否可以手动打开的安全性，从而更好地保证乘客的安全疏散。
本发明还满足了紧急出口装置车内与紧急入口装置车外的对紧急解锁开 门的不同功能需求。即：车内解锁需要发起请求信号，并由信号系统进行控制；而车外解锁能保证救援人员在车辆停止后，直接解锁车门，手动开门的需求。
优选的，上述车门紧急解锁控制方法还包括以下步骤：
S21、在手柄9允许操作的情况下，操作手柄9，解锁车门，解锁后的车门可以手动自由打开；
S22、通过车门控制单元检测车辆是否处于零速车辆线激活状态；若是，车门电机无堵转力，可以手动打开车门；若否，则进入步骤S23；
S23、车辆车门安全回路断开，且车门控制单元在关闭方向上启动车门驱动电机；
S24、检测车门是否关锁到位，若是，则车门驱动电机停在当前位置；若否，车门驱动电机驱动车门向关锁到位的位置关闭。
本实施例采用两级的安全风险防范，通过列车信号系统进行一级防范，通过车门控制单元进行二级防范。通过信号系统控制紧急出口装置的手柄9是否允许操作，避免人为误操作。当信号系统对车门禁止解锁车辆线信号控制失效，紧急出口装置手柄9处于允许操作状态；如果乘客操作紧急出口装置，此时由车门控制单元按照上述步骤S22-S24控制车门是否可以手动打开；若在车辆处于运动状态，车门控制单元将在关闭方向上启动车门驱动电机，以阻止车门被打开，仍然能从车辆级别进行风险防范，增强了车门系统本身抗风险能力。
进一步的技术方案中，还包括以下步骤：
S31、在乘客疏散事件结束后，手动复位手柄9；
S32、若车辆处于故障失电情况，则进入步骤S33；若若车辆没有处于故障失电情况，即在车辆得电情况下，则进入步骤S34；
S33、手动关闭车门，利用钥匙复位保护盖板7；
S34、电动驱动车门关闭，控制车辆车门安全回路闭合，利用钥匙复位保护盖板7，使车辆车门疏散请求回路处于未激活状态，控制车门禁止解锁车辆线信号有效，进而控制手柄9被手柄控制结构锁定，手柄9不允许操作。
车门解锁后，触发本地车门紧急解锁开关及锁到位开关，导致车辆安全回路断开，车辆无法启动。必须由授权人员通过钥匙复位保护盖板7，车辆才能恢复到正常状态，确保安全后再继续启动车辆，进一步提高了工作安全性。
优选的，步骤S13还包括：通过车门控制单元向列车信号系统发送疏散请求信号，并通过司机室显示屏显示相应的门紧急解锁信息；
步骤S23还包括：通过车门控制单元向列车信号系统发送紧急出口装置已操作信号；
步骤S34还包括：通过车门控制单元向列车信号系统发送紧急出口装置已复位信号。
本实施例中，当车辆车门疏散请求回路被激活，车门控制单元同时通过网络总线发出单门级的疏散请求网络信号给列车信号系统，方便监控。
乘客操作手柄9，解锁车门，车门控制单元同时通过网络总线发出单门级的紧急出口装置已操作网络信号给列车信号系统，方便监控。
当利用钥匙复位保护盖板7，手柄9不允许操作后，通过车门控制单元向列车信号系统发送紧急出口装置已复位信号，方便正常启动车辆。
本申请的车门控制单元不参与手柄9是否允许操作的控制，仅进行监控，保证了信号系统对该装置安全性控制的要求。
本发明的车门紧急解锁控制方法参与控制的车辆线包括：除零速车辆线、 车辆车门安全回路外，还有车辆车门疏散请求回路、车门禁止解锁车辆线，与列车信号系统实现了更好的交互，同时由车辆硬连线触发的信号安全性很高，尤其适用于采用无人驾驶运营模式的车辆车门。
请参考附图1-5，本发明实施例还提供了一种车门系统，包括车门和紧急出口装置，还包括列车信号系统；紧急出口装置包括：具有紧急操作腔的基座8；能够开闭紧急操作腔的保护盖板7；通过操作能够解锁车门的手柄9，手柄9设置在紧急操作腔；控制手柄9是否可操作的手柄控制结构；能够锁定保护盖板7以使保护盖板7处于关闭状态的盖板锁定结构，盖板锁定结构设置在紧急操作腔；用于驱使盖板锁定结构释放和锁定保护盖板7的盖板打开及复位结构1，盖板打开及复位结构1设置在基座8上；设置在紧急操作腔内的紧急疏散检测开关，紧急疏散检测开关由保护盖板7的打开或手柄9进行的不能解锁车门的小角度操作触发；当紧急疏散检测开关触发时，激活车辆车门疏散请求回路，由车辆车门疏散请求回路向列车信号系统发送疏散请求信号，列车信号系统接收疏散请求信号后，控制车辆停止在安全的区域内，以激活零速车辆线信号，并使得车门禁止解锁车辆线信号无效，进而控制手柄9被手柄控制结构释放，允许手柄9操作。
需要说明的是，手柄9通过钢丝绳拉动车门承载驱动机构上的解锁装置，实现车门的机械解锁，钢丝绳通过钢丝绳轮4和连接器5安装以及与解锁装置连接。
当发生紧急疏散事件时，通过操作盖板打开及复位结构1使盖板锁定结构释放保护盖板7，从而打开紧急出口装置的保护盖板7，或者在打开保护盖板7后，将手柄9进行不能解锁车门的小角度操作，进而触发紧急疏散检测开关， 激活车辆车门疏散请求回路，由车辆车门疏散请求回路向列车信号系统发送疏散请求信号，列车信号系统接收疏散请求信号后，控制车辆停止在安全的区域内，以激活零速车辆线信号，并使得车门禁止解锁车辆线信号无效，进而控制手柄9被手柄控制结构释放，允许手柄9操作，以解锁车门。
本发明通过打开保护盖板7或者小角度操作手柄9，并在车辆处于非零速状态时，激活车辆车门疏散请求回路，向列车信号系统发送疏散请求信号；利用列车信号系统控制车辆停止在安全的区域内，以激活零速车辆线信号，并控制车门禁止解锁车辆线信号无效，进而控制手柄9被手柄控制结构释放，允许手柄9操作；实现了在列车信号系统控车情况下，与列车信号系统的交互，从而更好的保证乘客安全的疏散。
综上所述，本发明提供的车门系统在保护盖板7打开或手柄9小角度操作后能激活车辆车门疏散请求回路，主动发出疏散请求信号，后续的手柄9是否允许操作由信号系统决定，能与列车信号系统进行交互，将安全风险由车门级别提高到整个车辆运营系统，从而有利于从更高级别进行风险防范和应对，强化了车辆及车门本身对紧急出口装置控制的安全风险防范能力，所以提高了车门是否可以手动打开的安全性，从而更好地保证乘客的安全疏散。
当采用通过小角度操作手柄9激活车辆车门疏散请求回路时，
在手柄9上设置二级位置，当手柄9操作一个小角度时，处于第一级位置，此时触发第一个限位开关，激活车辆车门疏散请求回路，发出疏散请求信号；在手柄控制结构未释放手柄9之前，手柄9无法再继续操作；当列车信号系统控制手柄控制结构释放手柄9时，手柄9可以允许继续操作一个较大角度，处于第二级位置的同时触发第二个限位开关，发出手柄9已操作信号，从而解锁 车门。
优选的，上述车门系统还包括手柄检测开关6，当手柄9被操作时手柄9上的手柄触发凸台91触发手柄检测开关6，从而控制车辆车门安全回路断开，并在车辆处于非零速状态时，通过车门控制单元在车门关闭方向上启动车门驱动电机，利用车门驱动电机驱动车门向关锁到位的位置关闭，以防止车门在非安全状态下被手动打开。
本实施例在手柄9操作后，利用手柄9上的手柄触发凸台91触发手柄检测开关6，通过车门控制单元检测车辆是否处于零速车辆线；若是，车门电机无堵转力，可以手动打开车门；若否，则控制车辆车门安全回路断开，并通过车门控制单元在关闭方向上启动车门驱动电机，使车门关锁到位，避免在车辆运行过程中车门被乘客拉开。
本实施例采用两级的安全风险防范，通过列车信号系统进行一级防范，通过车门控制单元进行二级防范。通过信号系统控制紧急出口装置的手柄9是否允许操作，避免人为误操作。当信号系统对车门禁止解锁车辆线信号控制失效，紧急出口装置手柄9处于允许操作状态；如果乘客操作紧急出口装置，此时由车门控制单元控制车门是否可以手动打开；若在车辆处于运动状态，车门控制单元将在关闭方向上启动车门驱动电机，以阻止车门被打开，仍然能从车辆级别进行风险防范，增强了车门系统本身抗风险能力。
具体的实施方式中，紧急疏散检测开关为盖板检测开关2；保护盖板7上设置有盖板开关防触发结构，当保护盖板7处于关闭状态时，盖板开关防触发结构驱使盖板检测开关2处于未触发状态；基座8上设置有盖板开关触发结构，当保护盖板7处于打开状态时，盖板开关触发结构触发盖板检测开关2。
本实施例的盖板检测开关2由保护盖板7的打开触发。当然，紧急疏散检测开关还可以为手柄9小角度操作检测开关，由手柄9进行的不能解锁车门的小角度操作触发。
盖板开关触发结构包括弹性触发件和能够旋转的盖板开关触发转动臂14，弹性触发件能够驱动盖板开关触发转动臂14向触发盖板检测开关2的方向旋转；
盖板开关防触发结构为盖板开关防触发杆13，当保护盖板7处于关闭状态时，盖板开关防触发杆13驱使盖板开关触发转动臂14向与盖板检测开关2分离的方向旋转，从而使得盖板检测开关2处于未触发状态；当保护盖板7打开后，盖板开关防触发杆13离开盖板开关触发转动臂14。如图5所示，当保护盖板7处于关闭状态时，盖板开关防触发杆13作用在盖板开关触发转动臂14上，使得其发生顺时针旋转，离开盖板检测开关2上的机械触点，从而使得盖板检测开关2处于未触发状态；当保护盖板7打开后，盖板开关防触发杆13与保护盖板7一起运动，离开原有位置，此时盖板开关触发转动臂14在弹性触发件的作用力下，逆时针旋转，触发盖板检测开关2。
为了简化结构，弹性触发件优选为套设在盖板开关触发转动臂14的转轴上的扭簧；当然，也可以为位于盖板开关触发转动臂14靠近盖板检测开关2一侧的弹性夹或弹性推杆。
盖板开关防触发结构还可以防触发凸起等。
本发明还可以通过检测保护盖板7位置的检测器，通过发送位置信号来利用控制器来控制盖板检测开关2是否处于触发状态。
为了简化结构，手柄控制结构为手柄控制电磁铁3，手柄控制电磁铁3设 置有锁闭销31，手柄控制电磁铁3在得电情况下，锁闭销31伸出锁住手柄9的手柄操作止挡92，使得手柄9无法操作；在失电情况下，锁闭销31处于收缩状态，使手柄9处于允许操作状态。
本申请利用手柄控制电磁铁3控制手柄9是否允许操作；在得电情况下，手柄控制电磁铁3内部的锁闭销31伸出，锁住操作手柄9的手柄操作止挡92，使得手柄9无法操作。当手柄控制电磁铁3在失电情况下，其内部的锁闭销31处于收缩状态，此时手柄9处于允许操作状态；一旦手柄9被操作，其手柄触发凸台91将触发手柄检测开关6。
可替换的，手柄控制结构还可以为电动推杆、控制气缸等。
本发明一具体的实施例中，保护盖板7上设置有盖板锁钩12；盖板锁定结构为能够与盖板锁钩12卡接配合的销钉，销钉通过旋转出入盖板锁钩12；盖板打开及复位结构1包括：与销钉固定连接的复位钥匙锁；能够驱动销钉向释放保护盖板7的方向旋转的盖板打开旋钮10，盖板打开旋钮10设置有位于销钉一侧的驱动突起；与复位钥匙锁配合的复位钥匙，复位钥匙能够驱使复位钥匙锁连带着销钉向锁定保护盖板7的方向旋转。
本实施例中，盖板打开及复位结构1上设置有销钉，保护盖板7关闭状态下与盖板锁钩12配合，锁定保护盖板7；如图3所示，手动顺时针旋转盖板打开旋钮10，使得盖板打开旋钮10与盖板复位钥匙锁11一起顺时针旋转，从而导致的销钉离开锁定位置并定位，从而释放保护盖板7。
保护盖板7复位时，由于盖板打开旋钮10仅在一侧设置驱动突起，手动反方向即逆时针旋转盖板打开旋钮10时，无法驱动销钉回转，仅能通过复位钥匙逆时针旋转盖板复位钥匙锁11，从而解除销钉的定位，使得销钉回复到 关闭状态重新与盖板锁钩12配合，锁定保护盖板7。
本申请在车门解锁后，触发本地车门紧急解锁开关及锁到位开关，导致车辆安全回路断开，车辆无法启动。必须由授权人员通过复位钥匙复位保护盖板7，车辆才能恢复到正常状态，确保安全后再继续启动车辆，进一步提高了工作安全性。
可以理解的是，上述复位钥匙可以为机械钥匙，也可以为电子钥匙。
本发明提供的紧急出口装置具有极高的安全性，尤其适用于无人驾驶的车辆车门系统，为无人驾驶车辆运营系统中车门作为紧急情况时的疏散出口提供了借鉴范例。
本发明还可以在紧急出口装置上或安装位置的附近加装指示灯，用于指示手柄9是否允许操作。该指示灯由车门控制单元根据输入的车门禁止解锁车辆线信号进行控制。
需要说明的是，本申请涉及的控制电路如下：
车辆车门安全回路：本地车门的关到位开关、锁到位开关及紧急解锁开关相关触点串联，同时并联隔离开关的常开触点，组成本地门安全回路，通过安全回路的输入/出口与其它门的安全回路输出/入口连接，串联组成车辆级别的车门安全回路。
车辆车门疏散请求回路：各个车门的紧急出口盖板检测开关2常闭触点串联，组成车辆级别的紧急疏散请求回路。
车辆设置车门禁止解锁车辆线，一方面输入给车门控制单元，用于车门控制单元的对该信号的监控；另一方面输入给紧急出口装置的手柄控制电磁铁3，用于对手柄9的控制。
车辆设置零速车辆线，作为控制信号输入给车门控制单元。只有在零速车辆线有效且车门禁止解锁车辆线无效的情况下，才能手动解锁并打开车门。
限位开关监控电路：与紧急出口装置相关的车门关到位开关、锁到位开关、紧急解锁开关、隔离开关、盖板检测开关2、手柄检测开关6通过相应触点作为输入信号接入车门控制单元，用于车门控制单元对各信号的监控，以及时判断紧急出口装置操作前/后的车门状态或故障信息。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
