实施例一
图1是本申请实施例一提供的智能火灾报警方法的流程图。根据不同的需求，该流程图中的执行顺序可以改变，某些步骤可以省略。
S11、接收火灾报警指令。
在一些实施例中，可以事先在终端上安装有火灾应用程序(下文简称为“火灾APP”)，所述火灾APP可以用于检测火灾险情、获取火灾信息以及接收火灾报警指令等。当用户发现有火灾险情或者认为有必要进行火灾报警时，可以通过所述终端的火灾APP手动输入火灾报警指令。用户输入的火灾报警指令可以包括以下一种或多种的组合：输入预设文字信息，例如，输入文字“火灾”；输入预设语音信息，例如，输入语音“报警”；触摸所述火灾APP的预设按钮或图标等。
在一些实施例中，还可以事先在所述终端上集成至少一种感测器，所述感测器可以为诸如热敏电阻等的热感测器，或者为检测诸如一氧化碳、二氧化碳、氢气或NOx等可指示火灾的气体的气体感测器，热感测器和/或气体感测器所检测到的信号可以被所述终端用来确定环境中是否存在火灾。即，可以由所述终端根据所述至少一种感测器检测到的信号及预设报警条件判断是否触发火灾报警指令，当确定至少一种感测器检测到的信号满足所述预设报警条件时，终端自动触发火灾报警指令。
所述预设报警条件为预先设置的报警条件，可以包括，但不限于：当检测到空气中的温度超过预设第一温度阈值，且在预设第一时间段内侦测到用户的输入操作时，确定满足所述预设报警条件；当检测到空气中的温度超过预设第二温度阈值时，确定满足所述预设报警条件；当检测到空气中的气体浓度超过预设第一气体浓度阈值，且在预设第二时间段内侦测到用户的输入操作时，确定满足所述预设报警条件；当检测到空气中的气体浓度超过预设第二气体浓度阈值时，确定满足所述预设报警条件。其中，所述预设第一温度阈值小于所述预设第二温度阈值，所述预设第一气体浓度阈值小于所述预设第二气体浓度阈值。所述预设第一时间段可以与所述预设第二时间段相同，也可以不相同。
设置所述预设第一温度阈值(例如，20度)小于所述预设第二温度阈值(例如，50度)及所述预设第一时间段，是为了当空气中的温度超过所述预设第一温度阈值但并没有超过所述预设第二温度阈值时，给用户缓冲时间，由用户根据火灾现场情况自行决定是否输入报警指令或者何时输入报警指令，例如，当发生火灾现场的范围较小，且周围有较便利的灭火设备，用户能够在所述预设第一时间段内将火情控制或者灭火时，可选择不触发报警指令。同时，当空气中的温度在所述预设第一时间段(例如，1分钟)内，由所述预设第一温度阈值骤升到所述预设第二温度阈值，而用户未来得及或无法输入操作时，能够自动且快速的触发报警指令。本文对于设置所述预设第一气体浓度阈值(例如，20％)小于所述预设第二气体浓度阈值(例如，30％) 及所述预设第二时间段(例如，30秒钟)的目的同上述温度所述，在此不再详细赘述。
所述终端侦测到用户输入的火灾报警指令时及/或侦测到满足所述预设报警条件时，即接收到了所述火灾报警指令，本申请对所述火灾报警指令的获取方式不做任何具体限定。
S12、响应所述火灾报警指令，获取多个感测器的感测信息。
在一些实施例中，所述感测信息可以包括，但不限于：可燃物的燃烧值、风向值、火灾现场的烟雾浓度值、温度值、火焰值、用户的心跳值、血压值及呼吸频率等。
在一些实施例中，所述多个感测器可以内置于终端中，也可以与终端通讯连接，所述多个感测器的感测信息可以通过以下方式获取：
1)通过读取内置于所述终端的至少一个感测器所检测到的信号来获取；
2)通过接收与所述终端通讯连接的外部装置来获取。
所述外部装置可以包括，但不限于：烟雾感测器、位置感测器、温度感测器、湿度感测器以及光敏感测器等。优选地，所述外部装置为烟雾感测器，当空气中的烟雾浓度为0.1mg/m 3时，烟雾感测器能够快速响应，响应时间小于30秒。
S13、根据所述感测信息判断所述火灾报警指令是否有效。
作为一种可选的实施方式，所述根据所述感测信息判断所述火灾报警指令是否有效可以包括：
分别将所述燃烧值及所述风向值映射到预设函数中得到映射后的燃烧值及映射后的风向值，其中，预设函数为S(x)＝1/(1+e -x)，x为映射前的变量值，S(x)为映射后的值；
比较所述映射后的燃烧值是否大于所述映射后的风向值；
若大于，则将所述映射后的燃烧值确定为最大值，否则，将所述映射后的风向值确定为最大值；
判断所述最大值是否大于预设火势趋势阈值；
若所述最大值大于或者等于所述预设火势趋势阈值，则确定所述火灾报警指令有效。
通过预设函数能将具有不同单位的燃烧值和风向值归一化到(0,1)的范围内且无量纲，然后结合可燃物的燃烧值及当前的风向值进一步判断终端当前所处的环境是否真的发生火灾，如果发生火灾且具有扩大的趋势，则确定所述火灾报警指令有效，能够避免用户无意识的启动火灾APP导致了触发火灾报警指令的发生。
作为另一种可选的实施方式，所述根据所述感测信息判断所述火灾报警指令是否有效可以包括：
对所述心跳值、所述血压值及所述呼吸频率进行比较；
确定所述心跳值、所述血压值及所述呼吸频率中的最小值；
判断所述最小值是否大于预设生理参数阈值，所述预设生理参数阈值为预先设置的生理参数，是表征用户处于意识不清醒状态的生理参数临界值；
若所述最小值大于或者等于所述预设生理参数阈值，则确定所述火灾报警指令有效。
通过结合用户的生理参数(如心跳、血压、呼吸频率)进一步判断用户当前是否处于意识不清醒状态，若用户当前处于意识不清醒状态，可以确定所述火灾报警指令有效。
当确定所述火灾报警指令有效时，执行步骤S14；当确定所述火灾报警指令无效时，执行步骤S15。
S14、获取火灾现场的火灾视频，并将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端。
在一些实施例中，可以通过预先设置的摄像头来拍摄火灾现场的实时火灾视频，所述摄像头可以对火灾现场进行360度无死角拍摄，所述摄像头可以与所述终端进行实时通信，所述终端能够实时获取所述摄像头拍摄的所述火灾视频并将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端。所述报警终端可以为报警平台中心，通常是119报警中心。
S15、输出火灾自救措施的提示，以引导用户进行自救。
当确定所述火灾报警指令无效时，可以输出火灾自救措施的提示，例如输入预设语音或者输入预设消防学习视频等以引导用户如何防止吸入过多浓烟、如何使用灭火设备、如何逃生等，能够使得用户在救援人员赶到之前进行自我救援，争取更多的生还机会。此外，当确定所述火灾报警指令无效时，不向所述报警终端发送火灾报警指令，还可以减少消防资源的浪费。
S16、获取所述火灾报警指令被发送至所述报警终端的时间。
终端将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端之后，获取当前发送的时间。
S17、若确定发送时间在白天，则实时获取道路的路况信息并向所述报警终端发送最优路径规划；若确定发送时间在夜晚，则实时获取道路的路灯信息并向所述报警终端发送最优路径规划。
通常，如果在白天发送火灾报警指令，报警终端一侧虽有足够的救援人员分配，但白天时，道路上人流量及车流量较大，有可能因为道路拥堵造成相关人员无法及时的赶往火灾现场。而如果在夜晚发送火灾报警指令，由于夜晚的不便及救援人员配备不充足等问题，很难在第一时间调配大量的执行人员执行救援工作，因而为了适应各种情况，所述终端可以根据火灾报警指令的发送时间来做出不同的操作。
如果所述火灾报警指令的发送时间是在白天，终端可以获取与报警终端之间的实时路况信息，所述路况信息包括：道路的质量信息及道路的拥堵信息，获取路面质量好、拥堵少的道路作为最优路径规划，以便报警终端的救援人员能以最快的速度及时地到达火灾现场进行救援，从而减少人员伤亡及财产损失。如果所述火灾报警指令的发送时间是在夜晚，还需要考虑额外的外界因素-亮度，终端则可以获取有照明设施且在正常工作的路段作为最优路径规划，不仅便于报警终端的救援人员能以最快的速度及时地到达火灾现场进行救援，还能确保救援人员在赶往火灾现场的路程中安全驾驶。
作为一种可选的实施方式，在接收到火灾报警指令时，所述方法还可以进一步包括：输出预设提示信息以提示用户输入火灾现场被困人数、火灾发生的原因；将用户输入的被困人数及火灾发生的原因发送至所述报警终端。
所述预设提示信息可以是以文字形式进行提示，也可以是以语音形式进行提示，用户根据所述预设提示信息输入火灾现场被困人数及火灾发生的原因(例如，可燃物自然、人为纵火、线路老化等)，并在接收到用户输入的提示信息后将携带有所述火灾现场被困人数、所述火灾发生的原因、所述火灾视频以及所述感测信息的火灾报警指令发送至所述报警终端，有利于所述报警终端的救援人员能够获得更多更详细且准确的火灾信息，便于报警终端的救援人员及时做出准确的火灾救援决策。
作为一种可选的实施方式，当确定所述火灾报警指令有效时，所述方法还可以包括：确定火灾现场的火灾等级；判断所述火灾等级是否大于预设火灾等级阈值；当确定所述火灾等级大于或者等于所述预设火灾等级阈值时，向用户房屋所属的管理人员的终端发送火灾告警信息。
所述火灾告警信息可以包括：所述终端当前所处的地理位置、火灾等级及所述火灾现场的火灾视频。所述预设火灾等级阈值为预先设置的火灾等级，是区分火灾现场的火灾等级为高等级或低等级的临界值。当火灾现场的火灾等级大于或者等于所述预设火灾等级阈值时，确定火灾等级为高等级，表明火灾现场的火灾较为严重，火灾现场的烟雾浓度较高、温度较高、火焰辐射较大，火灾危险程度较高，破坏力较强；当火灾现场的火灾等级小于所述预设火灾等级阈值时，确定火灾等级为低等级，表明火灾现场的烟雾浓度较低、温度较低、火焰辐射较小，火灾危险程度较低，破坏力较弱。
在一些实施例中，所述确定火灾现场的火灾等级具体可以包括：根据预设计算规则对所述烟雾浓度值、温度值以及火焰值进行加权求和，得到所述火灾现场的火灾等级，其中，所述预设计算规则为：yi＝(e xi-e -xi)/(e xi+e -xi)，S＝a1*|y1|+a2*|y2|+a3*|y3|，且a1+a2+a3＝1，xi代表所述烟雾浓度值、温度值以及火焰值，a1为预先对烟雾浓度值设置的权重值，a2为预先对温度值设置的权重值，a3为预先对火焰值设置的权重值，S为计算得到的火灾等级。yi＝(e xi-e -xi)/(e xi+e -xi)的目的是将所述烟雾浓度值、温度值以及火焰值归一化到(-1,1)的范围内，再通过取绝对值进一步归一化到(0,1)的范围内。
当确定所述火灾等级为高等级时，即在确定火灾现场的火灾比较严重的情况下，向房屋所属的管理人员的终端发送火灾告警信息，能够有利于房屋所属的管理人员在所述报警终端的救援人员到达火灾现场之前，及时地进行前期的救援工作，尽最大可能的争取一切救援机会，避免报警终端的救援人员出警不及时而耽误救援。
作为一种可选的实施方式，在所述获取火灾现场的火灾视频之后，所述方法还可以进一步包括：根据所述火灾视频分析火灾发生的原因，确定火灾类型；根据所述火灾类型控制对应的灭火装置进行灭火。
在一些实施例中，终端可以预先存储多个火灾类型及对应的灭火装置。 所述火灾类型可以根据国家标准修订发布的《火灾分类》进行设置。所述灭火装置可以通过物联网实现网络连接，并可以智能控制。
所述根据所述火灾视频分析火灾发生的原因具体包括：提取视频中的每一帧图像；判断每一帧图像中是否出现了预设物质；当确定出现了预设物质时，根据所述预设物质确定火灾类型。例如，判断火灾视频中出现了如木材、棉、毛、麻、纸张火灾等时，确定火灾类型为A类火灾；判断火灾视频中出现了如汽油、煤油、原油、甲醇、乙醇、沥青、石蜡火灾等时，确定火灾类型为B类火灾；判断火灾视频中出现了如钾、钠、镁、铝镁合金火灾等，确定火灾类型为D类火灾；判断火灾视频中出现了烹饪器具时，确定火灾类型为F类火灾。
举例来说，当确定火灾类型为E类火灾，即带电火灾时，则可以控制闸刀开关自动断电，从而切断房屋内的线路电源，控制火灾的进一步恶化。又如，当确定火灾类型为F类火灾，即烹饪器具内的烹饪物火灾时，则可以控制烹饪器具自动关闭。

以上所述，仅是本申请的具体实施方式，但本申请的保护范围并不局限于此，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
下面结合第2至3图，分别对实现上述智能火灾报警方法的终端的功能模块及硬件结构进行介绍。
实施例二
图2为本申请智能火灾报警装置较佳实施例中的功能模块图。
在一些实施例中，所述智能火灾报警装置20运行于终端中。所述智能火灾报警装置20可以包括多个由程序代码段所组成的功能模块。所述智能火灾报警装置20中的各个程序段的程序代码可以存储于存储器中，并由至少一个处理器所执行，以执行(详见图1及其相关描述)对火灾的智能报警。
本实施例中，所述终端的智能火灾报警装置20根据其所执行的功能，可以被划分为多个功能模块。所述功能模块可以包括：接收模块201、获取模块202、判断模块203、发送模块204、提示模块205、路径规划模块206及控制模块207。本申请所称的模块是指一种能够被至少一个处理器所执行并且能够完成固定功能的一系列计算机可读指令段，其存储在存储器中。在一些实施例中，关于各模块的功能将在后续的实施例中详述。
接收模块201，用于接收火灾报警指令。
在一些实施例中，可以事先在终端上安装有火灾应用程序(下文简称为“火灾APP”)，所述火灾APP可以用于检测火灾险情、获取火灾信息以及接收火灾报警指令等。当用户发现有火灾险情或者认为有必要进行火灾报警时，可以通过所述终端的火灾APP手动输入火灾报警指令。用户输入的火灾报警指令可以包括以下一种或多种的组合：输入预设文字信息，例如，输入文字“火灾”；输入预设语音信息，例如，输入语音“报警”；触摸所述火灾APP的预设按钮或图标等。
在一些实施例中，还可以事先在所述终端上集成至少一种感测器，所述感测器可以为诸如热敏电阻等的热感测器，或者为检测诸如一氧化碳、二氧化碳、氢气或NOx等可指示火灾的气体的气体感测器，热感测器和/或气体感测器所检测到的信号可以被所述终端用来确定环境中是否存在火灾。即，可以由所述终端根据所述至少一种感测器检测到的信号及预设报警条件判断是否触发火灾报警指令，当确定至少一种感测器检测到的信号满足所述预设报警条件时，终端自动触发火灾报警指令。
所述预设报警条件为预先设置的报警条件，可以包括，但不限于：当检测到空气中的温度超过预设第一温度阈值，且在预设第一时间段内侦测到用户的输入操作时，确定满足所述预设报警条件；当检测到空气中的温度超过预设第二温度阈值时，确定满足所述预设报警条件；当检测到空气中的气体浓度超过预设第一气体浓度阈值，且在预设第二时间段内侦测到用户的输入操作时，确定满足所述预设报警条件；当检测到空气中的气体浓度超过预设第二气体浓度阈值时，确定满足所述预设报警条件。其中，所述预设第一温度阈值小于所述预设第二温度阈值，所述预设第一气体浓度阈值小于所述预设第二气体浓度阈值。所述预设第一时间段可以与所述预设第二时间段相同，也可以不相同。
设置所述预设第一温度阈值(例如，20度)小于所述预设第二温度阈值(例如，50度)及所述预设第一时间段，是为了当空气中的温度超过所述预设第一温度阈值但并没有超过所述预设第二温度阈值时，给用户缓冲时间，由用户根据火灾现场情况自行决定是否输入报警指令或者何时输入报警指令，例如，当发生火灾现场的范围较小，且周围有较便利的灭火设备，用户 能够在所述预设第一时间段内将火情控制或者灭火时，可选择不触发报警指令。同时，当空气中的温度在所述预设第一时间段(例如，1分钟)内，由所述预设第一温度阈值骤升到所述预设第二温度阈值，而用户未来得及或无法输入操作时，能够自动且快速的触发报警指令。本文对于设置所述预设第一气体浓度阈值(例如，20％)小于所述预设第二气体浓度阈值(例如，30％)及所述预设第二时间段(例如，30秒钟)的目的同上述温度所述，在此不再详细赘述。
所述接收模块201侦测到用户输入的火灾报警指令时及/或侦测到满足所述预设报警条件时，即接收到了所述火灾报警指令，本申请对所述火灾报警指令的获取方式不做任何具体限定。

作为一种可选的实施方式，所述判断模块203根据所述感测信息判断所述火灾报警指令是否有效可以包括：
分别将所述燃烧值及所述风向值映射到预设函数中得到映射后的燃烧值及映射后的风向值，其中，预设函数为S(x)＝1/(1+e -x)，x为映射前的变量值，S(x)为映射后的值；
比较所述映射后的燃烧值是否大于所述映射后的风向值；
若大于，则将所述映射后的燃烧值确定为最大值，否则，将所述映射后的风向值确定为最大值；
判断所述最大值是否大于预设火势趋势阈值；
若所述最大值大于或者等于所述预设火势趋势阈值，则确定所述火灾报警指令有效。
通过预设函数能将具有不同单位的燃烧值和风向值归一化到(0,1)的范围内且无量纲，然后结合可燃物的燃烧值及当前的风向值进一步判断终端当前所处的环境是否真的发生火灾，如果发生火灾且具有扩大的趋势，则确定所述火灾报警指令有效，能够避免用户无意识的启动火灾APP导致了触发火灾报警指令的发生。
作为另一种可选的实施方式，所述判断模块203根据所述感测信息判断所述火灾报警指令是否有效可以包括：
对所述心跳值、所述血压值及所述呼吸频率进行比较；
确定所述心跳值、所述血压值及所述呼吸频率中的最小值；
判断所述最小值是否大于预设生理参数阈值，所述预设生理参数阈值为预先设置的生理参数，是表征用户处于意识不清醒状态的生理参数临界值；
若所述最小值大于或者等于所述预设生理参数阈值，则确定所述火灾报警指令有效。
通过结合用户的生理参数(如心跳、血压、呼吸频率)进一步判断用户当前是否处于意识不清醒状态，若用户当前处于意识不清醒状态，可以确定所述火灾报警指令有效。
所述获取模块202，用于当所述判断模块203确定所述火灾报警指令有效时获取火灾现场的火灾视频。
发送模块204将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端。
在一些实施例中，可以通过预先设置的摄像头来拍摄火灾现场的实时火灾视频，所述摄像头可以对火灾现场进行360度无死角拍摄，所述摄像头可以与所述终端进行实时通信，所述终端能够实时获取所述摄像头拍摄的所述火灾视频并将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端。所述报警终端可以为报警平台中心，通常是119报警中心。
提示模块205，用于当所述判断模块203确定所述火灾报警指令无效时，输出火灾自救措施的提示，以引导用户进行自救。
当确定所述火灾报警指令无效时，可以输出火灾自救措施的提示，例如输入预设语音或者输入预设消防学习视频等以引导用户如何防止吸入过多浓烟、如何使用灭火设备、如何逃生等，能够使得用户在救援人员赶到之前进行自我救援，争取更多的生还机会。此外，当确定所述火灾报警指令无效时，不向所述报警终端发送火灾报警指令，还可以减少消防资源的浪费。
所述获取模块202，还用于在所述发送模块204将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端之后，获取所述火灾报警指令被发送至所述报警终端的时间。
路径规划模块206，用于在所述获取模块202确定发送时间在白天后，实时获取道路的路况信息并向所述报警终端发送最优路径规划。所述路径规划模块206，还用于在所述获取模块202确定发送时间在夜晚后，实时获取道路的路灯信息并向所述报警终端发送最优路径规划。
通常，如果在白天发送火灾报警指令，报警终端一侧虽有足够的救援人员分配，但白天时，道路上人流量及车流量较大，有可能因为道路拥堵造成相关人员无法及时的赶往火灾现场。而如果在夜晚发送火灾报警指令，由于夜晚的不便及救援人员配备不充足等问题，很难在第一时间调配大量的执行人员执行救援工作，因而为了适应各种情况，所述终端可以根据火灾报警指令的发送时间来做出不同的操作。
如果所述火灾报警指令的发送时间是在白天，终端可以获取与报警终端之间的实时路况信息，所述路况信息包括：道路的质量信息及道路的拥堵信息，获取路面质量好、拥堵少的道路作为最优路径规划，以便报警终端的救援人员能以最快的速度及时地到达火灾现场进行救援，从而减少人员伤亡及财产损失。如果所述火灾报警指令的发送时间是在夜晚，还需要考虑额外的外界因素-亮度，终端则可以获取有照明设施且在正常工作的路段作为最优路径规划，不仅便于报警终端的救援人员能以最快的速度及时地到达火灾现场进行救援，还能确保救援人员在赶往火灾现场的路程中安全驾驶。
作为一种可选的实施方式，在所述接收模块201接收到火灾报警指令时，所述提示模块205还用于：输出预设提示信息以提示用户输入火灾现场被困人数、火灾发生的原因；所述发送模块204还用于将用户输入的被困人数及火灾发生的原因发送至所述报警终端。
所述预设提示信息可以是以文字形式进行提示，也可以是以语音形式进行提示，用户根据所述预设提示信息输入火灾现场被困人数及火灾发生的原因(例如，可燃物自然、人为纵火、线路老化等)，并在接收到用户输入的提示信息后将携带有所述火灾现场被困人数、所述火灾发生的原因、所述火灾视频以及所述感测信息的火灾报警指令发送至所述报警终端，有利于所述报警终端的救援人员能够获得更多更详细且准确的火灾信息，便于报警终端的救援人员及时做出准确的火灾救援决策。
作为一种可选的实施方式，当所述判断模块203确定所述火灾报警指令有效时，所述判断模块203还用于：确定火灾现场的火灾等级及判断所述火灾等级是否大于预设火灾等级阈值；所述发送模块204还用于：当所述判断模块203确定所述火灾等级大于或者等于所述预设火灾等级阈值时，向用户房屋所属的管理人员的终端发送火灾告警信息。
所述火灾告警信息可以包括：所述终端当前所处的地理位置、火灾等级及所述火灾现场的火灾视频。所述预设火灾等级阈值为预先设置的火灾等级，是区分火灾现场的火灾等级为高等级或低等级的临界值。当火灾现场的火灾等级大于或者等于所述预设火灾等级阈值时，确定火灾等级为高等级，表明火灾现场的火灾较为严重，火灾现场的烟雾浓度较高、温度较高、火焰辐射较大，火灾危险程度较高，破坏力较强；当火灾现场的火灾等级小于所述预设火灾等级阈值时，确定火灾等级为低等级，表明火灾现场的烟雾浓度较低、温度较低、火焰辐射较小，火灾危险程度较低，破坏力较弱。
在一些实施例中，所述确定火灾现场的火灾等级具体可以包括：根据预设计算规则对所述烟雾浓度值、温度值以及火焰值进行加权求和，得到所述火灾现场的火灾等级，其中，所述预设计算规则为：yi＝(e xi-e -xi)/(e xi+e -xi)，S＝a1*|y1|+a2*|y2|+a3*|y3|，且a1+a2+a3＝1，xi代表所述烟雾浓度值、温度值以及火焰值，a1为预先对烟雾浓度值设置的权重值，a2为预先对温度值设置的权重值，a3为预先对火焰值设置的权重值，S为计算得到的火灾等级。yi＝(e xi-e -xi)/(e xi+e -xi)的目的是将所述烟雾浓度值、温度值以及火焰值归一化 到(-1,1)的范围内，再通过取绝对值进一步归一化到(0,1)的范围内。
当确定所述火灾等级为高等级时，即在确定火灾现场的火灾比较严重的情况下，向房屋所属的管理人员的终端发送火灾告警信息，能够有利于房屋所属的管理人员在所述报警终端的救援人员到达火灾现场之前，及时地进行前期的救援工作，尽最大可能的争取一切救援机会，避免报警终端的救援人员出警不及时而耽误救援。
作为一种可选的实施方式，在所述获取模块202获取火灾现场的火灾视频之后，所述判断模块203还用于：根据所述火灾视频分析火灾发生的原因，确定火灾类型；控制模块207根据所述火灾类型控制对应的灭火装置进行灭火。
在一些实施例中，终端可以预先存储多个火灾类型及对应的灭火装置。所述火灾类型可以根据国家标准修订发布的《火灾分类》进行设置。所述灭火装置可以通过物联网实现网络连接，并可以智能控制。
所述判断模块203根据所述火灾视频分析火灾发生的原因具体包括：提取视频中的每一帧图像；判断每一帧图像中是否出现了预设物质；当确定出现了预设物质时，根据所述预设物质确定火灾类型。例如，判断火灾视频中出现了如木材、棉、毛、麻、纸张火灾等时，确定火灾类型为A类火灾；判断火灾视频中出现了如汽油、煤油、原油、甲醇、乙醇、沥青、石蜡火灾等时，确定火灾类型为B类火灾；判断火灾视频中出现了如钾、钠、镁、铝镁合金火灾等，确定火灾类型为D类火灾；判断火灾视频中出现了烹饪器具时，确定火灾类型为F类火灾。
举例来说，当确定火灾类型为E类火灾，即带电火灾时，则可以控制闸刀开关自动断电，从而切断房屋内的线路电源，控制火灾的进一步恶化。又如，当确定火灾类型为F类火灾，即烹饪器具内的烹饪物火灾时，则可以控制烹饪器具自动关闭。
根据所述火灾视频确定火灾类型并控制对应的灭火装置进行灭火，能够有效的减少用户的输入操作，尤其是在用户处于意识模糊无法输入任何操作时，能够自动根据火灾视频确定火灾类型，并进而控制相应的灭火装置进行灭火，有效的阻断了火灾发生的源头，降低火势。
综上所述，本申请所述的智能火灾报警装置20，通过火灾APP实现快速报警及通过侦测是否满足预设报警条件实现自动报警，在接收到报警指令时，先获取终端当前所处环境的感测信息，并根据所述感测信息进一步确定火灾报警指令有效后，获取火灾现场的火灾视频，并将携带有所述火灾视频以及所述感测信息的火灾报警指令发送至报警终端。能够避免错误报警，并在报警时提供更多更详细且准确的火灾信息，便于报警终端的救援人员及时做出准确的火灾救援决策。同时获取发送至所述报警终端的火灾报警指令的时间，根据发送时间，选择不同的最优路径规划提供给所述报价终端，以便报警终端的救援人员能以最快的速度及时地到达火灾现场进行救援。
其次，在确定火灾报警指令无效时，输出火灾自救措施的提示，以引导用户进行自救，不仅能够使得用户在救援人员赶到之前进行自我救援，争取 更多的生还机会，还可在确定所述火灾报警指令无效时，不向所述报警终端发送火灾报警指令，减少消防资源的浪费。另外，根据所述火灾视频分析火灾发生的原因，确定火灾类型；根据所述火灾类型控制对应的灭火装置进行灭火，能够阻断火灾发生的源头，降低火势。
