在一些实施例中，抑爆部件可以包括第一抑爆部件9和第二抑爆部件12中的至少一种。在一些实施例中，第一抑爆部件9可以沿轴向设置在管道本体 的内周壁上，构成抑爆通道。在一些实施例中，第二抑爆部件12可以沿抑爆通道的轴向间隔设置。
图9是根据本申请说明书一些实施例所示的第一抑爆部件的结构示意图。第一抑爆部件9可以用于减小、抑制或避免***对管道本体内壁造成的影响。例如，第一抑爆部件9可以阻断***传递至管道本体内壁的路径、吸收和/或分散传递至管道本体内壁的***能量、降低***物浓度等。在一些实施例中，第一抑爆部件9可以通过多种方式实现减小、抑制或避免***对管道本体内壁造成的影响。在一些实施例中，第一抑爆部件9可以覆盖在管道本体的内壁上，用于阻断***传递至管道本体内壁的路径。

在一些实施例中，第一抑爆部件9可以包括缓冲减振结构，用于吸收和/或分散传递至管道本体内壁的***能量。缓冲减振结构可以包括弹性结构和/或弹性材料。弹性结构可以包括平板状结构、弯板状结构、弹簧、弹簧片等结构中的一种或多种。弹性材料可以包括铝合金、橡胶等中的一种或多种。
在一些实施例中，第一抑爆部件9可以包括导热结构和/或导热材料，用于吸收***能量产生的热能。导热结构可以是导热材料制成的板状结构、层状结构等。导热材料可以包括铜、铝、锌、石墨、氮化铝、碳化硅等中的一种或多种。在一些实施例中，第一抑爆部件9还可以包括具有高强度性、高耐磨性和/或高耐腐蚀性等的其他结构和/或材料。
在一些实施例中，第一抑爆部件9可以采用抑爆材料制成。图7是根据本申请说明书一些实施例所示的抑爆材料的结构示意图。抑爆材料是指能够减小或抑制***冲击的材料。抑爆材料可以包括金属材料等，例如，铝合金箔材等。在一些实施例中，抑爆材料可以具有多孔六边形结构。多孔六边形结构是指多个六边形单元形成的蜂窝状结构。
可以理解的，蜂窝状结构是指由多个网格单元互相连接并排列形成的结构，网格单元可以是圆形、椭圆形、三角形、多边形等中的一种或多种。在一些实施例中，网格单元的边长可以是3-8mm。例如，4±0.5mm、5±0.5mm、5.5±0.5mm、6±0.5mm、7±0.5mm等。
通过设置抑爆材料为多孔六边形结构，可以使抑爆材料具有良好的强度和缓冲能力，能够吸收***冲击中的部分能量，从而削弱***冲击。
在一些实施例中，如图7、图9所示，第一抑爆部件9可以通过前述铝合金箔卷绕制成，构成抑爆通道，抑爆通道可以覆盖在管道本体内壁上。在一些实施例中，抑爆通道可以与管道本体内壁相抵接，或通过其他方式连接。例如，粘接、焊接、螺纹连接、卡接、磁吸等中的一种或多种。在一些实施例中，第一抑爆部件9和第二抑爆子部件具有多孔六边形结构。
第二抑爆部件可以用于减小、抑制或避免***沿管道本体轴向造成的影响。可以理解的，管道本体内产生的***冲击大部分会沿着管道本体轴向传递，第二抑爆部件12沿抑爆通道的轴向间隔设置，可以有效减小***产生的冲击。在一些实施例中，第二抑爆部件12可以是多种形状。例如，长方体状、多层片状等。
在一些实施例中，第二抑爆部件12包括至少一个第二抑爆子部件。第二抑爆子部件可以指构成第二抑爆部件的下级部件。例如，第二抑爆部件12为多层片状部件时，第二抑爆子部件可以为第二抑爆部件12中的单层片状部件。
可以理解的，管道本体内的天然气可以通过第二抑爆子部件。当管道本体内发生***时，第一抑爆部件9可以削弱朝向管道本体侧壁的部分***冲击，从而减小或避免管道本体侧壁受到的影响。第二抑爆子部件可以对沿着管道本体轴向的***冲击形成部分阻挡，多层第二抑爆子部件可以逐渐削弱沿着管道本体轴向的***冲击。
在一些实施例中，第二抑爆部件12可以沿抑爆通道的轴向等间距设置。可以理解的，如此设置能够使第二抑爆部件12均匀分布在抑爆通道内，在两个 第二抑爆部件12之间的区域形成抑爆单位区域，多个抑爆单位区域的抑爆能力相同，避免第二抑爆部件12分布不均而出现局部区域抑爆能力弱的问题。
在一些实施例中，第二抑爆部件12可以通过多种方式与第一抑爆部件9固定连接连，以提高抑爆部件整体的强度，避免第二抑爆部件12发生位移而导致抑爆通道内局部区域抑爆能力减弱。例如，第二抑爆部件12与第一抑爆部件9可以通过粘接、焊接、螺纹连接、卡接等方式中的中的一种或多种进行连接。
在一些实施例中，第二抑爆子部件也可以由抑爆材料制成。关于抑爆材料的更多内容可以参见前文相关描述。
在一些实施例中，第二抑爆子部件可以沿抑爆通道的径向设置在抑爆通道内。通过使第二抑爆子部件沿抑爆通道的径向设置在抑爆通道内，能够减小第二抑爆子部件占据的面积，方便第二抑爆子部件的安装。
在一些实施例中，第二抑爆子部件可以相对于抑爆通道的径向倾斜设置在抑爆通道内。例如，第二抑爆子部件相对于抑爆通道的径向的倾斜角度可以是30°、45°、60°等。通过使第二抑爆子部件倾斜设置在抑爆通道内，可以增加第二抑爆子部件占据的面积，在发生***时，第二抑爆子部件可以吸收更多的***冲击，减小***冲击影响的范围。
在一些实施例中，如图12、图13所示，第二抑爆部件12可以包括至少三个第二抑爆子部件，至少三个第二抑爆子部件之间等间距设置。通过设置至少三个第二抑爆子部件，当***冲击穿过单第二抑爆部件12时，可以多次削弱***冲击，从而增强单个第二抑爆部件12的抑爆能力。
在一些实施例中，相邻两个第二抑爆子部件之间的距离，小于相邻两个第二抑爆部件12之间的距离。避免多个第二抑爆子部件距离较小而影响天然气正常运输，也能够减小使用成本。
在一些实施例中，相邻第二抑爆子部件相互错位设置。错位设置是指相邻第二抑爆子部件上的六边形单元，在抑爆通道的径向上相互错开。例如，在抑爆通道的轴向上，前一个第二抑爆子部件的六边形单元的中心，可以与后一 个第二抑爆子部件的六边形单元的顶点在同一直线上。又例如，在抑爆通道的轴向上，前一个第二抑爆子部件的六边形单元的顶点，可以与后一个第二抑爆子部件的六边形单元的顶点在同一直线上，两个第二抑爆子部件与该顶点对应的边可以错开一定角度。
当发生***时，***冲击可以依次穿过多个第二抑爆子部件。当***冲击从最前端的第二抑爆子部件穿过时，部分***冲击被六边形单元的边吸收，部分***冲击从六边形单元的中部穿过。穿过的部分***冲击可以与后一个六边形单元的边接触而被减弱。以此能够增强多个第二抑爆子部件的抑爆能力。
在一些实施例中，错位角度可以基于第二抑爆部件12的目标数量确定。错位角度是指不同部件安装时交错的角度。相邻第二抑爆子部件的错位角度可以为，前一个第二抑爆子部件的六边形单元的中心与后一个第二抑爆子部件的距离最近的六边形单元的中心的连线，相对于抑爆通道的轴线的夹角。目标数量是第二抑爆部件12的个数。在一些实施例中，错位角度可以与第二抑爆部件12的目标数量正相关。关于错位角度、目标数量的更多内容，可以见见图3及其相关描述。
在一些实施例中，第二子抑爆部件可以通过第二处理形成，第二处理可以包括叠压切缝扩展。叠压切缝扩展是指将多层材料叠加在一起，在加压状态下切割形成所需的形状。例如，可以将多层蜂窝铝合金箔叠加在一起，在加压状态下切割形成圆柱体、圆球体、正方体或长方体等中的一种或多种。
通过设置第一抑爆部件和第二抑爆部件，能够在管道本体内发生***时，从管道本体内的径向和轴向分别抑爆，减弱或避免***冲击对管道本体侧壁造成影响，同时使***冲击在沿轴向传递的过程中被逐渐削弱，减小***冲击的作用范围和影响。
图2是根据本说明书一些实施例所示的抑爆部件的填充方法的示例性流程图。如图2所示，流程200包括下述步骤。在一些实施例中，流程200可以由抑爆部件填充装置执行。
抑爆部件填充装置可以指用于执行抑爆部件的填充方法的设备。在一些实施例中，抑爆部件填充装置包括至少一个处理器以及至少一个存储器；至少一个存储器用于存储计算机指令；至少一个处理器用于执行计算机指令中的至少部分指令以实现抑爆部件填充方法。
存储器可以用于存储数据和/或指令。存储器可以包括一个或多个存储组件，每个存储组件可以是一个独立的设备，也可以是其他设备的一部分。在一些实施例中，存储器可包括随机存取存储器(RAM)、只读存储器(ROM)、大容量存储器、可移动存储器、易失性读写存储器等或其任意组合。
处理器可以处理从其他设备或***组成部分中获得的数据和/或信息。处理器可以基于这些数据、信息和/或处理结果执行程序指令，以执行一个或多个本说明书中描述的功能。
步骤210，将抑爆材料进行第一处理制成第一抑爆部件，将抑爆材料进行第二处理制成第二抑爆部件。
在一些实施例中，第一抑爆部件和第二抑爆部件具有多孔六边形结构。关于抑爆材料、第一抑爆部件、第二抑爆部件和多孔六边形结构的更多内容可以参见图1及其相关描述。
在一些实施例中，第一处理可以包括对抑爆材料进行切割和卷绕的操作。例如，可以将抑爆材料基于预设尺寸切割，再卷绕形成中空筒状的第一抑爆部件。
在一些实施例中，第二处理可以包括对抑爆材料进行叠压切缝扩展的操作。例如，可以将多张抑爆材料进行叠压之后，基于预设尺寸切割构成多层片状的第二抑爆部件。
步骤220，确定第二抑爆部件的目标数量。
目标数量是指确定的用于组装抑爆部件的第二抑爆部件的数量。
在一些实施例中，处理器可以通过多种方式确定目标数量。例如，处理器可以基于获取用户输入信息确定目标数量。又例如，处理器可以基于历史数 据确定目标数量。仅作为示例的，处理器可以将历史数据中，装配与当前管道具有相同长度的历史管道时使用的第二抑爆部件的历史数量的平均值作为目标数量。
在一些实施例中，处理器还可以获取管道信息、第二抑爆部件的候选数量；通过防爆模型确定最大***压力进而确定目标数量。关于基于防爆模型确定最大***压力进而确定目标数量的更多内容可以参见图3及其相关描述。
步骤230，将目标数量的第二抑爆部件与第一抑爆部件组装，构成抑爆部件。
在一些实施例中，处理器可以基于间隔距离，将第二抑爆部件沿抑爆通道的径向间隔设置在抑爆通道内，组合成抑爆部件。间隔距离可以基于经验或需求设定。关于抑爆通道的具体说明可以参见图1及其相关说明。
步骤240，将抑爆部件放置于天然气管道的管道本体内。
在一些实施例中，处理器可以将组装好的抑爆部件从天然气管道的管道本体的一端伸入并推进，直至抑爆部件放置于天然气管道的管道本体内。
本说明书的一些实施例通过对抑爆材料进行处理、组装并安置，完成对天然气管道的安全加固，第一抑爆部件和第二抑爆部件组合放置，提高了管道运输的安全性。
图3是根据本说明书一些实施例所示的防爆模型的示意图。
在一些实施例中，处理器可以获取管道信息311、第二抑爆部件的候选数量312；基于管道信息311和候选数量312，通过防爆模型320确定最大***压力330，防爆模型320为机器学习模型；基于最大***压力330、候选数量312，确定目标数量340。
管道信息311是指与管道相关的特征信息。管道信息311可以包括管道尺寸、运输物质、管道材质等。例如，管道信息可以是内径a米、外径b米、长度10米的水泥材质的天然气管道。
在一些实施例中，处理器可以通过多种方式获取管道信息311。例如， 处理器可以通过获取用户输入信息获取管道信息。又例如，处理器可以通过抑爆部件填充装置内部或外部的存储装置获取管道信息。
候选数量312是指供选择的第二抑爆部件的数量。候选数量312可以通过多种方式确定。例如，处理器可以基于历史数据中第二抑爆部件的历史数量随机生成第二抑爆部件的候选数量。
最大***压力330是指发生***时管道内承受的最大的***压力。可以理解的，天然气管道存在压力承受阈值(即管道能够承受的最大的压力阈值)，当管道内的最大***压力大于压力承受阈值时，管道就可能出现破损、断裂等风险情况。压力承受阈值可以基于实验、管道参数等预先确定。
在一些实施例中，处理器可以基于管道信息311和候选数量312，通过防爆模型320确定最大***压力330。防爆模型320指用于确定天然气管道对应的最大***压力的模型。在一些实施例中，防爆模型320可以是机器学习模型，例如，神经网络(Neural Networks，NN)模型等。
在一些实施例中，防爆模型的输入可以包括管道信息311和候选数量312；输出可以是最大***压力330。关于管道信息、候选数量和最大***压力的更多内容可以参见前述相关描述。
在一些实施例中，防爆模型320可以通过多个带有第一标签的第一训练样本训练得到。第一训练样本可以包括样本管道的样本管道信息和样本候选数量，第一标签可以包括前述样本管道对应的实际最大***压力。第一训练样本可以基于历史数据获取，第一标签可以通过人工标注的方式确定。
在一些实施例中，处理器可以基于前述样本管道的样本管道信息和样本候选数量，通过抑爆实验方法对前述样本管道进行抑爆实验，并基于抑爆实验中获取的前述样本管道***时的压力数据，确定最大***压力作为第一标签。关于抑爆实验方法、压力数据获取的更多内容可以参见图4及其相关描述。
在一些实施例中，处理器可以基于最大***压力330、候选数量312，通过多种方式确定目标数量340。例如，处理器可以将最大***压力低于压力承 受阈值、二者差异在预设幅度内、且数值最大的候选数量作为第二抑爆部件的目标数量。预设幅度可以基于经验或需求设定。
在一些实施例中，处理器可以基于管道信息、目标数量，确定第二抑爆部件的安装间距。例如，处理器可以将管道信息中管道长度与目标数量的比值(可以理解的，第二抑爆部件为等间距设置)，作为第二抑爆部件的安装间距。
可以理解的，在天然气管道的实际使用过程中，由于管道材质、管道尺寸等因素的不同，发生***的***压力、破坏性等可能存在较大差异。通过基于实验数据获取模型训练所需的样本和标签，可以获得更贴合实际、准确度较高的防爆模型；通过获取管道信息、第二抑爆部件的候选数量，基于防爆模型确定最大***压力，进而确定目标数量，可以对管道参数等数据进行分析，综合考虑多种影响因素，获取准确的最大***压力，进而确定合理的第二抑爆部件的目标数量，便于后续进行天然气管道的装配。
在一些实施例中，将目标数量的第二抑爆部件与第一抑爆部件进行组装时，处理器可以确定不同第二抑爆部件之间的错位角度，将目标数量的第二抑爆部件错位设置，且不同第二抑爆部件之间的错位角度不同。
可以理解的，第二抑爆部件可以平行地间隔设置，也可以基于错位角度间隔设置。在一些实施例中，错位可以包括平移错位和旋转错位。第二抑爆部件之间的错位角度是指安装第二抑爆部件时，不同第二抑爆部件的位置交错的角度。
在一些实施例中，错位角度可以基于第二抑爆部件的目标数量确定。例如，错位角度可以是360°与第二抑爆部件的目标数量的比值。可以理解的，此处的错位角度是基于360°进行确定的，即所有第二抑爆部件安装完毕后，整体错位角度(即第一个第二抑爆部件与最后一个第二抑爆部件之间的旋转角度)为360°，在实际安装过程中，若需要其他数值的整体错位角度，例如，720°、540°等，可以将之前基于360°确定的错位角度与需要的整体错位角度对应比值(例如，720°的对应比值为360°的2倍、540°的对应比值为360° 的1.5倍等)的乘积作为实际安装的错位角度。
在一些实施例中，处理器还可以通过防爆模型确定错位角度。在一些实施例中，防爆模型的输入还可以包括预设错位角度。对应的，在进行模型训练时，第一训练样本还可以包括样本管道的样本预设错位角度，通过抑爆实验获取第一标签时，需将多组第二抑爆部件按对应样本预设错位角度在管道内进行布设。
预设错位角度可以基于经验或需求预设获取。关于防爆模型的输入、输出和训练及标签等更多内容可以参见前文相关描述。
在一些实施例中，处理器还可以将多组第二抑爆部件按照错位角度安置于天然气管道的管道本体内。
在一些实施例中，第二抑爆部件可以按照错位角度，旋转式地安置于抑爆通道内。
本说明书的一些实施例按照一定的错位角度分别安装第二抑爆部件，可以获取较好的防爆性能。此外，由于安装的错位角度不同，会对阻隔抑爆材料的防爆性能造成不同影响，通过防爆模型，并基于实验数据获取模型训练的错位角度相关的样本和标签数据，可以在获取合理的错位角度的同时，大大降低构建模型和训练模型的人力时间成本。
图4是根据本说明书一些实施例所示的抑爆实验方法的示例性流程图。抑爆实验方法可以由实验装置执行。流程400包括以下步骤：
步骤410，获取填充好的实验管道。
实验管道是指用于进行实验的管道。例如，宽×高×长为120mm×120mm×1000mm、厚度为20mm的长方形管道。关于实验管道的更多内容可以参见下文关于图5的相关描述。
在一些实施例中，可以基于抑爆部件的填充方法，将第二抑爆部件与第一抑爆部件进行组装，再将组装好的抑爆部件放置于实验管道的管道本体内，以获取填充好的实验管道。
关于管道本体、第一抑爆部件、第二抑爆部件、抑爆部件的填充方法的更多内容可以参见图1-图3的相关描述。在一些实施例中，进行多次实验时，每次实验对应的填充好的实验管道中，第二抑爆部件的数量和/或位置可以不同。
步骤420，通过气泵排出实验管道内的气体。
在一些实施例中，处理器可以通过气泵，采用排空气法将实验管道内的原有气体泵出。在一些实施例中，气泵可以向实验管道内泵入气体(例如，甲烷等)，替换掉实验管道内原有的空气。
步骤430，通过气瓶、流量控制装置向实验管道内配置目标气体，基于静置时间进行静置。
在一些实施例中，气瓶可以与实验管道通过流量控制装置连通，处理器可以通过流量控制装置控制气瓶内的气体流通到实验管道内。关于气瓶、流量控制装置的更多内容可以参见下文图5的相关描述。
目标气体是指实验需要的、气瓶中存储的气体。例如，目标气体可以是甲烷或甲烷混合物等。在一些实施例中，目标气体可以是浓度为9.5％的甲烷。
在一些实施例中，处理器可以控制气泵向实验管道内的泵入空气，替换掉实验管道内的原有气体。空气替换完成后，处理器可以控制气泵关闭，控制流量控制装置打开，以使气瓶内的气体(如，甲烷等)流通到实验管道内与实验管道内的空气混合，以配置目标气体。
当实验管道内通入预设体积的目标气体后，处理器可以控制流量控制装置关闭并使实验管道保持静止，以静置目标气体。
静置时间是指目标气体需要静置的时长。可以理解的，使目标气体静置，有利于使目标气体分布均匀，避免目标气体分布不均而对实验数据造成干扰。
在一些实施例中，静置时间可以通过多种方式确定。例如，基于查表、经验或历史实验数据获取。
在一些实施例中，静置时间可以基于实验管道内第二抑爆部件的目标数量和第二抑爆部件的位置确定。
可以理解的，第二抑爆部件的数量和位置可能会影响气体的扩散速度。第二抑爆部件的数量越多，气体的扩散速度可能会越慢。第二抑爆部件的位置分布越密集，气体的扩散速度可能会越慢。
在一些实施例中，处理器可以基于实验管道内第二抑爆部件的目标数量和第二抑爆部件的位置，通过多种方式确定静置时间。例如，第二抑爆部件的目标数量越多、位置分布越密集，处理器可以设定静置时间越长。又例如，处理器可以根据基于第二抑爆部件的历史数量、历史位置及其对应的静置时间构建第二预设表。处理器可以根据当前实验管道内第二抑爆部件的目标数量和第二抑爆部件的位置，通过查询第二预设表，确定静置时间。
在一些实施例中，实验装置可以基于实验结果的可靠度确定静置时间。
实验结果的可靠度是指***实验的结果的可靠程度。在一些实施例中，实验结果的可靠度可以通过多种方式获取。例如，处理器可以通过获取用户输入信息确定可靠度。
在一些实施例中，处理器可以基于多次重复实验的实验结果差异值，确定可靠度。例如，处理器可以计算至少两个实验结果的差异值并与差异阈值进行比较，若差异值大于差异阈值，则基于实验结果差异过阈的次数和总实验次数，确定可靠度。仅作为示例的，可以确定可靠度为1-实验结果差异过阈的次数/总实验次数；也可以基于至少两个实验结果的离散程度计算确定实验结果的可靠度。差异阈值可以基于经验或需求预设。
在一些实施例中，实验结果的可靠度与静置时间负相关，实验结果的可靠度越低，则设置越长的静置时间，以防止静置时间过短，气体混合不均匀或分布不均匀影响实验结果。
在一些实施例中，处理器可以将标准静置时间与可靠度的比值确定为静置时间。标准静置时间是指预先设定的静置时间，标准静置时间可以基于经验或需求预设。在一些实施例中，可以预设静置时间的最大限值，避免因为可靠度过低导致静置时间过大的问题。
通过精准确定静置时间，保证气体能够在实验管道内均匀分布，避免花费过多的时间等待气体均匀扩散，有利于提高实验效率。
步骤440，通过同步控制器控制点火装置点火，响应于实验管道内发生***，通过摄像装置获取所述实验管道内的燃烧信息，通过传感装置获取所述实验管道内的压力数据。
燃烧信息是指实验管道内的燃烧相关的信息。燃烧信息可以包括火焰速度、目标气体是否燃烧、燃烧时间、燃烧温度等。在一些实施例中，处理器可以通过摄像装置获取燃烧信息。例如，如图14所示，处理器可以控制摄像装置在点火装置点火时开启，实时拍摄实验管道内的现象，基于拍摄的照片、视频等，通过图像处理模型等方式获取燃烧信息。
压力数据是指与实验管道内的压力相关的数据。例如，***冲击对实验管道的内壁施加的压力等。在一些实施例中，如图15所示，处理器可以通过传感装置获取压力数据。关于传感装置的更多内容可以参见下文图5的相关描述。
在一些实施例中，处理器可以基于样本管道的样本管道信息和样本候选数量，确定相应尺寸的实验管道的管道本体和相应数量的第二抑爆部件，基于抑爆部件的填充方法，将第二抑爆部件、第一抑爆部件与实验管道进行组装，获取填充好的实验管道；通过气泵排出实验管道内的气体；通过气瓶、流量控制装置向实验管道内配置目标气体，基于静置时间进行静置；通过同步控制器控制点火装置点火，响应于实验管道内发生***，通过传感装置获取实验管道内的样本压力数据；基于样本压力数据确定最大***压力作为第一标签。关于样本管道、样本管道信息、样本候选数量、第一标签等的更多内容可以参见图3及其相关描述。

在一些实施例中，处理器可以通过负压装置对实验管道进行抽气操作，抽气时间基于实验管道内抑爆部件的数量和抑爆部件的位置确定。
抽气操作是指利用负压装置抽取实验管道内部空气的操作。在一些实施例中，处理器可以基于气压传感器获取实验管道内的气压信息，响应于气压信息中的气压达到负压阈值时，控制负压装置停止抽气。负压阈值可以指低于标准大气压的阈值。例如，负压阈值可以为标准大气压的80％，即将目标气体通入实验管道并静置一段时间后，实验管道内为80％的空气和20％的目标气体混合物。负压阈值可以基于经验或需求预设。
抽气时间是指实验管道内的气压达到负压阈值时所需的时间。
在一些实施例中，处理器可以基于实验管道内抑爆部件的数量和抑爆部件的位置，通过多种方式确定抽气时间。例如，处理器可以基于历史实验管道内的抑爆部件的历史数量、历史位置及其对应的抽气时间构建第三预设表。处理器可以基于当前实验管道内抑爆部件的数量和抑爆部件的位置，通过查询第三预设表，确定当前抽气时间。
在一些实施例中，处理器还可以基于负压阈值、实验管道信息、第二抑爆部件的目标数量、第二抑爆部件的位置、候选抽气时间、抽气功率确定目标抽气时间；获取抽气功率下的实际抽气时间；响应于达到负压阈值的实际抽气时间与目标抽气时间满足预设条件，判断存在管道泄露，并确定可靠度。关于负压阈值、管道信息、第二抑爆部件的目标数量、第二抑爆部件的位置的更多内容可以参见图1-5的相关描述。
候选抽气时间是指可供选择的抽气时间。在一些实施例中，处理器可以通过获取用户输入信息、获取历史信息等获取候选抽气时间。
抽气功率是指负压装置抽气时的功率。在一些实施例中，抽气功率可以 基于经验或需求预设。
实际抽气时间是指达到负压阈值时实际所需抽气时间。在一些实施例中，处理器可以基于气压传感器、负压装置及计时装置获取实际抽气时间。

在一些实施例中，抽气模型620的输出可以是目标抽气时间630。
在一些实施例中，抽气模型620可以通过多个带有第二标签的第二训练样本训练得到。第二训练样本可以包括样本实验管道的管道信息、样本第二抑爆部件的目标数量、样本第二抑爆部件的错位角度、样本候选抽气时间、样本抽气功率和样本负压阈值。第二标签可以包括前述样本实验管道对应的实际抽气时间。

在一些实施例中，当实际抽气时间与目标抽气时间接近时(例如，当前气压和负压阈值的差值与负压阈值的比值小于20％时等)，可以适当提高传感装置对实验管道内压力数据的监测频率(例如，提高20％到50％等，监测频率可以基于经验或需求预设)，或适当降低抽气功率(例如，降低20％到50％ 等)，以避免造成过度抽气，使实验管道的管道内部的压力数据波动，影响实验结果，也能避免压力数据监测不够及时，造成误差的问题。
预设条件可以包括实际抽气时间与目标抽气时间的差异超出时间差异阈值。时间差异阈值可以基于经验或需求预设。
可以理解的，当达到负压阈值的实际抽气时间与目标抽气时间满足预设条件时，表征实验管道可能出现了管道泄漏等问题，以致影响实验结果的可靠度。关于可靠度的更多内容可以参见图4及其相关描述。
在一些实施例中，当实际抽气时间与目标抽气时间满足预设条件，且差异大于预设时间阈值时，处理器可以设置可靠度为0。此时，静置时间保持不变。关于静置时间的相关内容可以参见图4及其相关内容。
本说明书的一些实施例中，实验管道内的第二抑爆部件的目标数量以及错位角度不同时，会影响实验管道内气体的实际体积，同时也对负压风机的抽气效率产生影响，通过使用训练好的抽气模型对实验管道的管道信息、第二抑爆部件的目标数量和错位角度等数据进行分析，可以快速地确定比较合理的抽气时间，进而可以有效保证实验结果的可靠性。

实施例3
实施例3为将实施例2填充完成的天然气管道进行的抑爆实验，具体为：如图4和图5所示，一种抑爆实验方法，该抑爆实验方法所需的实验装置包括用于放置天然气管道的实验管道8、甲烷气瓶4(又可称作气瓶)、气泵6、流量控制器5(又可称作流量控制装置)、脉冲点火器3(又可称作点火装置)、同步控制器2、压力传感器10(又可称作传感装置)、高速摄影仪7(又可称作摄像装置)和计算机1(又可称作处理器)。在一些实施例中，实验管道8与流量控制器5之间通过通气管道11连通，流量控制器5与甲烷气瓶4通过通气管道11连通，实验管道8与气泵6的输出端之间通过通气管道11连通。在一些实施例中，压力传感器10用于检测实验管道8内的压力，高速摄影仪7用于观察实验管道8实验情况。在一些实施例中，计算机1分别与同步控制器2和压力传感器10连接，同步控制器2与脉冲点火器3连接，脉冲点火器3连接实验管道8，实验管道8上设置有泄爆口。在一些实施例中，抑爆实验方法可以包括如下步骤：

S5、***结束后，关闭实验装置并清理实验管道8。
在一些实施例中，管道本体的形状可以为长方形和圆柱形。当管道本体为长方形管道时，其尺寸可以为120mm×120mm×1000mm，厚度可以为20mm。在一些实施例中，进行抑爆实验时，采用的甲烷浓度可以为9.5％。在一些实施例中，可以先在管道本体内填充阻隔抑爆体9、然后在中间每个阻隔防爆片组12等间隔处放有一、三或五片阻隔防爆片，构成各个实验组，每组进行一次抑爆实验。
可以理解的，在中间每个阻隔防爆片组12等间隔处分别放有一片、两片、三片、五片蜂窝状的多孔六边形结构的阻隔防爆片，可以构成四种实验工况进行实验。在一些实施例中，基于前述四种工况各进行一组抑爆实验，并与不加抑爆材料的情况下的相关实验数据进行对比，通过分析不同工况下不同时间的最大***压力和火焰速度、不同工况下***的最大压力和最大火焰速度，可以得出抑爆效果最好的实验工况，具体实验工况如下表1：
实验一：按照工况a首先在实验管道8内配置一定浓度(9.50％)的甲烷气体，等待3-5分钟后，然后打开高速摄影仪7，调整好拍摄位置，高速摄影仪7用于拍摄管道内的火焰***燃烧情况；再打开同步控制器2，控制脉冲点火器 3点火同时打开压力传感器10记录压力数据；***结束后，关闭实验设备并清理设备。
实验二：按照工况b，在每个阻隔防爆片组12等间隔处放有两片阻隔防爆片，将阻隔防爆材料送入至实验管道8，打开气泵6用排空气法排出管道内剩余气体后，实验管道8另一侧用PVC薄膜封堵作为泄爆口，使用流量控制器5通入工况所要求的一定体积分数量(9.50％)的甲烷气体，并静置3-5分钟，使甲烷气体分散均匀，然后打开高速摄影仪7，调整好拍摄位置，高速摄影仪7用于拍摄实验管道8内的火焰***燃烧情况，再打开同步控制器2，控制脉冲点火器3点火的同时，打开压力传感器10记录压力数据；***结束后，关闭实验装置并清理实验管道8。
实验三：按照工况c，在每个阻隔防爆片组12等间隔处放有三片阻隔防爆片，将阻隔防爆材料送入至实验管道8，打开气泵6用排空气法排出管道内剩余气体后，在实验管道8另一侧用PVC薄膜封堵作为泄爆口，使用流量控制器5通入工况所要求的一定体积分数量(9.50％)的甲烷气体，并静置3-5分钟，使甲烷气体分散均匀，然后打开高速摄影仪7，调整好拍摄位置，高速摄影仪7用于拍摄实验管道8内的火焰***燃烧情况，再打开同步控制器2，控制脉冲点火器3点火同时打开压力传感器10记录压力数据；***结束后，关闭实验装置并清理实验管道8。
实验四：按照工况d，在每个阻隔防爆片组12等间隔处放有五片阻隔防爆片，将阻隔防爆材料送入至实验管道8，打开气泵6用排空气法排出管道内剩余气体后，在实验管道8另一侧用PVC薄膜封堵作为泄爆口，使用流量控制器5通入工况所要求的一定体积分数量(9.50％)的甲烷气体，并静置3-5分钟，使甲烷气体分散均匀，然后打开高速摄影仪7，调整好拍摄位置，高速摄影仪7用于拍摄实验管道8内的火焰***燃烧情况，再打开同步控制器2，控制脉冲点火器3点火同时打开压力传感器10记录压力数据；***结束后，关闭实验装置并清理实验管道8。
如下表2所示，将基于不同填充方式填充抑爆材料时和不填充抑爆材料时，对应的甲烷抑爆效果进行对比，可以看到抑爆材料对甲烷***的削弱效果较为明显。抑爆实验中，甲烷的最大***压力分别为11.304、9.036、11.203，将实验一至实验四的实验结果进行对比，可以看出与不加抑爆材料的实验一的实验结果相比，实验二至实验四的实验结果中，最大***压力、最大火焰速度均下降，最大速度到达的时间也相应延长，这说明添加阻隔抑爆材料对于甲烷***均有一定的抑爆效果，工况c最大***压力下降最明显，最大火焰速度下降明显，最大火焰速度达到的时间最长，达到最大火焰速度时火焰长度最长，因此实验表明只要加了阻隔抑爆材料，就能对甲烷的***有一定的抑制效果，在实验管道8四周都加了阻隔抑爆材料之后，有稍微明显的抑爆效果，同时中间每个阻隔防爆片组12等间隔处放有三片阻隔防爆片时抑爆效果最好。
