具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的描述中，除非另有明确的规定和限定，术语“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，也可以是两个元件内部的连通；可以是通讯连接；可以是电连接。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
请结合参阅图1，图1为本申请一些实施例提供的灭火控制方法的流程图。
所述灭火控制方法可应用于一灭火系统，所述灭火系统包括灭火装置，如图1所示，所述灭火控制方法包括：
S101：获取所述待保护设备的至少一个预设部位的火焰特征数据。
其中，火焰特征数据可以包括火焰的多个特征，比如火焰发出的光的强度、光谱、频率以及火焰的温度等等特征。
S102：根据所述至少一个预设部位的火焰特征数据判断是否存在火焰。
当确定存在火焰时，执行步骤S103：根据所述至少一个预设部位的火焰特征数据确定所述灭火装置的处置方式。
S104：基于所确定的处置方式控制所述灭火装置执行相应的操作。
从而，通过执行相应的操作以使得工作人员及时发现火情并采取相应的措施以避免火情扩散。
其中，所述预设部位上安装有火焰传感器和/或温度传感器，以获取所述火焰特征数据。
一些实施例中，所述处置方式包括报警、报警并灭火和灭火的其中一种。从而，在存在火焰时，可以提醒附近的工作人员所述待保护设备着火，由工作人员自行灭火，当没有工作人员进行灭火时，所述灭火装置启动灭火功能进行灭火以避免火情扩散，由于工作人员自行灭火的成本比使用灭火装置进行灭火的成本低一些，因此，能够在尽可能节约灭火成本的前提下避免火情扩散，同时也允许所述待保护设备在运行过程中没有工作人员守着的情况出现。
进一步地，一些实施例中，当确定存在火焰时，根据所述火焰特征数据确定所述灭火装置的处置方式，包括：当确定存在火焰时，根据所述火焰特征数据确定火焰大小和/或起火点位置，以及根据确定的所述火焰大小和/或起火点位置确定所述灭火装置的处置方式。
一实施例中，当火焰大小在第一预设范围值内时，确定所述灭火装置的处置方式为报警；当火焰大小在第二预设范围值内时，确定所述灭火装置的处置方式为报警并灭火，其中，所述第一预设范围值中的最大值小于所述第二预设范围值中的最小值，当火焰大小在第一预设范围值内时。
由于火焰大小在第一预设范围值内时，火焰还较小，可以通过报警提醒工作人员来进行灭火，就不用启动灭火装置的灭火功能，节约灭火成本；当火焰大小在第二预设范围值内时，火焰较大，此时继续报警提醒工作人员发生火情，另一方面启动灭火装置的灭火功能进行灭火以避免火情扩散导致更大的经济损失。
另一实施例中，当起火点位置为核心位置(比如容易进一步扩大火情的位置)，确定所述灭火装置的处置方式为报警并灭火；当起火点位置为边缘位置(比如不容易进一步扩大火情 的位置)时，确定所述灭火装置的处置方式为报警。
由于边缘位置不容易进一步扩大火情，因此，处置方式为报警，通过提醒工作人员进行灭火，以尽可能节约灭火成本，但是当着火点为核心位置时，核心位置容易进一步扩大火情，因此处置方式为报警并灭火，以避免火情快速扩散导致更大的经济损失。
再一实施例中，当起火点位置为边缘位置且火焰大小在第一预设范围值内时，确定所述灭火装置的处置方式为报警；起火点位置为核心位置且火焰大小在第一预设范围值内时、起火点位置为核心位置且在第二预设范围值内时、起火点位置为边缘位置且火焰大小在第二预设范围值内时，确定所述灭火装置的处置方式为报警并灭火。
从而，起火点位置为边缘位置且火焰大小在第一预设范围值内时，通过报警提醒工作人员进行灭火，以尽可能节约灭火成本，起火点位置为核心位置且火焰大小在第一预设范围值内时、起火点位置为核心位置且在第二预设范围值内时、起火点位置为边缘位置且火焰大小在第二预设范围值内时，确定所述灭火装置的处置方式为报警并灭火，可以避免火情快速扩散导致更大的经济损失。

其中，每个预设部位可以均设有火焰传感器和/或温度传感器，由于一些火焰传感器的阻抗值随火焰的大小变化，因此，可以根据阻抗值(或者电流值、电压值)的大小来确定火焰大小，同时，由于当出现火焰时，越靠近火焰位置的火焰传感器的阻抗值越小，越靠近火焰位置的温度越高，因此，可以综合多个火焰传感器和/或温度传感器检测到的火焰特征数据判断起火点的位置。
进一步地，一些实施例中，所述灭火控制方法还包括：当所述处置方式包括报警并灭火和灭火的任意一种时，根据确定的所述火焰大小确定阻燃剂的剂量；基于所确定的处置方式与所确定的阻燃剂的剂量控制所述灭火装置执行相应的操作。

进一步地，一些实施例中，所述灭火控制方法还包括：获取预设的灵敏度档位数据；根据所述灵敏度档位数据以及所述火焰特征数据确定所述灭火装置的处置方式。
比如，火焰大小分为一级火焰、二级火焰、三级火焰与四级火焰，其中，火焰的大小为一级火焰>二级火焰>三级火焰>四级火焰；灵敏度分为第一档灵敏度与第二档灵敏度，其中，第一档灵敏度比第二档灵敏度更加灵敏，当灭火装置为第一档灵敏度时，发生四级火焰时所述灭火装置的处置方式为报警，发生一级火焰、二级火焰与三级火焰时灭火装置的处置方式为报警并灭火。当灭火装置为第二档灵敏度时，发生三级火焰与四级火焰时所述灭火装置的处置方式为报警，发生一级火焰与二级火焰时灭火装置的处置方式为报警并灭火。
根据用户的需求不同，有的用户更倾向于避免麻烦喜欢直接使用灭火装置进行灭火，有的更倾向于在工作人员发现及时的情况下通过工作人员使用其他方式进行灭火以降低灭火成本，因此设置灵敏度档位以满足用户不同的需求。

请参考图8～图11，图8为本申请一实施例中的外置灭火系统1a的结构示意图；图9为本申请一实施例中的灭火装置100的立体结构示意图；图10为本申请一实施例中的灭火装置100的拆解示意图；图11为本申请一实施例中的外置灭火系统1a的模块示意图。
如图8所示，所述外置灭火系统1a包括灭火装置100、气管12a、第一控制器13a(如图11所示)和传感器14。如图9所示，所述灭火装置100上设置有出气口115。如图8所示，所述气管12a的一端与所述出气口115连通，另一端用于连接到一待保护设备2的工作区域21b内；所述第一控制器13a与所述灭火装置100之间电性连接；所述传感器14用于设置在所述待保护设备2的工作区域21b，并与所述第一控制器13a之间通信连接；其中，所述第一控制器13a根据所述传感器14获取的感测数据确定所述待保护设备2内着火时，控制所述灭火装置100释放灭火气体并通过所述气管12a进入所述待保护设备2内部进行灭火。
从而，本申请中，待保护设备2可以是但不限于激光雕刻设备、激光切割设备等。灭火装置100设于待保护设备2的外部，灭火装置100和待保护设备2之间通过气管12a连接，传感器14设于待保护设备2的工作区域21b内，可以实时检测待保护设备2内的火焰信息而得到感测数据，第一控制器13a根据传感器14获取的感测数据确定待保护设备2内着火时，控制灭火装置100释放灭火气体并通过所述气管12a进入所述待保护设备2内部进行灭火，可以实现自动灭火。相较于待保护设备内置灭火方式，本申请的外置灭火系统1a的设置位置更加灵活，可以减小待保护设备2的整体体积，并可以兼容不同类型的待保护设备2，兼容性更高。
一些实施例中，请参考图12，所述灭火装置100包括灭火气体储存容器20a和刺破装置10。所述刺破装置10内形成容纳腔50，所述灭火气体储存容器20a的预设部分穿设固定于所述刺破装置10，所述出气口115与所述容纳腔50内部连通。
其中，所述灭火气体储存容器20a的瓶身位于所述容纳腔50外，能够减小所述容纳腔50的体积，有利于所述灭火气体储存容器20a内的灭火剂形成的灭火气体快速充满所述容纳腔50并从所述容纳腔50流出以灭火，并且，所述灭火气体储存容器20a的瓶身位于所述容纳腔50外，使得在更换所述灭火气体储存容器20a时，能够从所述容纳腔50外直接进行更换，无需将所述刺破装置10拆解后才能进行灭火气体储存容器20a的更换。
如图9所示，一些实施例中，所述灭火装置100具有外部壳体111a。如图10所示，所述外部壳体111a内形成收容腔112a。所述灭火气体储存容器20a和刺破装置10位于所述收容腔112a内，所述外部壳体111a上设置有所述出气口115。所述出气口115与所述收容腔112a内部连通。所述气管12a可以插接于所述出气口115上。可以理解的是，存储于所述灭火气体储存容器20a中的灭火剂的压强大于所述收容腔112a内的压强，在所述灭火气体储存容器20a被刺破时，灭火气体储存容器20a内的灭火剂会释放至所述收容腔112a内并升华形成灭 火气体。另一些实施例中，所述气管12a可以穿过所述出气口115进入所述收容腔112内并直接连通于所述刺破装置10的所述容纳腔50。因此，所述灭火气体储存容器20a内的气体直接经所述气管12a喷出。
一些实施例中，所述灭火气体储存容器20a内的灭火剂可以是但不限于二氧化碳、七氟丙烷、三氟甲烷、六氟丙烷等。本实施例中，所述灭火气体储存容器20a内的灭火剂为二氧化碳。在其它实施例中，所述灭火气体储存容器20a内的灭火剂可为其它惰性气体。一些实施例中，所述灭火气体储存容器20a可以是一个或者多个，所述刺破装置10充当一个或者多个所述灭火气体储存容器20a的安装支架。当需要刺破时，所述刺破装置10同时刺破一个或者多个所述灭火气体储存容器20a，灭火剂从所述灭火气体储存容器20a的刺破的空隙中流出充满所述收容腔112a，然后经所述气管12a进入所述待保护设备2内部进行灭火。
一些实施例中，所述传感器14用于设置在所述待保护设备2的工作区域21b的内壁上。另一些实施例中，所述传感器14可以通过中间元件设置于所述待保护设备2的工作区域21b内。
一些实施例中，请参考图8，所述传感器14包括火焰传感器141。所述火焰传感器141用于获取火焰传感数据，所述第一控制器13a基于所述火焰传感器141所获取的火焰传感数据判断所述待保护设备2内是否着火。
一些实施例中，所述火焰传感器141的数量为至少四个，四个所述火焰传感器141用于间隔设置在所述待保护设备2的工作区域21b内壁的不同位置上，以通过不同位置的所述火焰传感器141从不同的角度获取所述火焰传感数据用于判断是否着火。
一些实施例中，四个所述火焰传感器141间隔设置在所述待保护设备2的工作区域21b的顶壁22b的四个对角位置处以通过不同位置的所述火焰传感器141从不同的角度来获取火焰传感数据用于判断是否着火。
一些实施例中，每个所述火焰传感器141的检测范围呈锥形状，且获取预设距离范围内的火焰传感数据。每个所述火焰传感器141所获得的火焰传感数据大于预设值时，确定该火焰传感器141的预设距离范围内发生火焰。四个所述火焰传感器141间隔设置在所述待保护设备的工作区域21b的顶壁22b的四个对角位置处，因而可以分别检测所述待保护设备2的工作区域21b的顶壁22b的四个对角位置的预设距离范围内是否发生火焰。
一些实施例中，由于每个所述火焰传感器141的检测范围呈锥形状，且用于获取预设距离范围内的火焰传感数据。因此，当四个所述火焰传感器141中的较多个数的火焰传感器141检测出火焰时，表明着火面积较大；反之，当四个所述火焰传感器141中的较少个数的火焰传感器141检测出火焰时，表明着火面积较小。此外，根据四个所述火焰传感器141中检测到火焰的所述火焰传感器141的位置，可以确定着火位置。因此，可以通过检测到火焰的所述火焰传感器141的个数来确定着火面积的大小，进而，所述第一控制器13a可以根据四个所述火焰传感器141的火焰传感数据确定着火面积和/或着火位置。
另一些实施例中，所述火焰传感器141的数量为五个，其中，四个所述火焰传感器141用于间隔设置在所述待保护设备2的工作区域21的四个内侧壁上，另外一个所述火焰传感器141设置在所述待保护设备2的工作区域21的顶壁上。
从而，可以在所述待保护设备2的工作区域21的不同位置可以设置火焰传感器141，以实现对待保护设备21的工作区域21的不同位置的着火面积和/或着火位置的检测。
一些实施例中，请再次参考图11，所述传感器14还包括激光头传感器142时，所述激光头传感器142的数量为至少一个，所述激光头传感器142既可以获取工作区域21内的实时 温度数据，也可以获取工作区域21内的实时火焰传感数据；一些实施例中，所述激光头传感器142用于设置在所述待保护设备2的激光头23的侧壁上，以感测所述待保护设备2的工作区域21b是否着火。可以理解的是，在其它实施例中，所述激光头传感器142可以设于所述待保护设备2的其他位置上，在此不做限定。
从而，本申请中，可以通过所述火焰传感器141和所述激光头传感器142的结合，可以更准确的判断所述待保护设备2的工作区域21b内是否着火，减少误判机率，也可以在所述火焰传感器141失效的情况下，由所述激光头传感器142进行检测是否着火，实现双重保险。
一些实施例中，请再次参考图8，所述外置灭火系统1a还包括线缆15，所述线缆15连接在所述传感器14和所述第一控制器13a之间，以实现所述传感器14和所述第一控制器13a之间的通信连接。
一些实施例中，请参考图13，所述外置灭火系统1a还包括若干固线块17，所述固线块17将所述线缆15固定在所述待保护设备2的工作区域21b的内壁上。
