实施例一
本申请给出一种打火检测方法，请参考图1，其为本申请所提 供的打火检测方法的第一流程示意图。
如图1所示，该方法包括以下步骤：
S101，接收隔离芯片的输出信号。
需要说明的是，本申请提供的检测方法执行在与隔离芯片连接的控制器上，该控制器还与待测系统连接。
例如，请参考图2，其为本申请提供的打火检测方法的电路结构示意图。图2中的GND表示接地，VDD为隔离芯片的电源引脚，Input为隔离芯片的输入引脚，Output为隔离芯片的输出引脚。如图2所示，隔离芯片由两个电源提供电能，隔离芯片左侧连接待测系统，隔离芯片右侧还连接控制器。
本申请中，隔离芯片两端的隔离电源可以为直流电源，例如，可以为3～5V的直流电源。
如图2所示，隔离芯片可以接收与待测系统相关的输出信号，并根据与待测系统相关的输出信号，向控制器输出自身的输出信号，因此，控制器就可以根据隔离芯片的输出信号，检测待测系统是否发生打火现象。
需要说明的是，本申请对隔离芯片的型号和类型不进行特别限定。例如，隔离芯片可以采用Si86XX型号的隔离芯片。
具体的，本申请中，隔离芯片的输出信号为隔离芯片根据与待测系统相关的输出信号得到的。
在一个具体的实现过程中，与待测系统相关的输出信号可以为电压信号。
需要说明的是，本申请中，与待测系统相关的输出信号的数目为至少两个，控制器可以接收到的隔离芯片的输出信号的数目为至少一个。
例如，可以在待测系统中选择至少两个不同的位置连接隔离芯片，并向隔离芯片输出这至少两个不同位置上与待测系统相关的输出信号。与隔离芯片连接的待测系统的具体位置可以根据实际需要进行选择，本申请对此不进行特别限定。
请参考图3，其为本申请中信号流向示意图。如图3所示，隔 离芯片可以接收到的与待测系统相关的输出信号为待测信号和基准信号，本申请不进行特别限定。如图3所示，隔离芯片接收到待测信号和基准信号后，可以输出自身的输出信号给控制器，以便于控制器可以根据接收到的隔离芯片的输出信号，检测待测系统是否发生打火现象。
以待测系统为电池包为例进行具体说明。隔离芯片接收到的与待测系统相关的输出信号可以包括但不限于：电池包的总正电压信号、电池包的总负电压信号和电池包的外壳电压信号中的至少两个。其中，可以将电池包的总正电压信号、电池包的总负电压信号作为如图3所示的待测信号，将电池包外壳的电压信号作为如图3所示的基准信号。
其中，电池包的总正电压信号可以包括但不限于：电池包的输入总正电压信号和电池包的输出总正电压信号中的至少一个。电池包的总负电压信号可以包括但不限于：电池包的输入总负电压信号和电池包的输出总负电压信号中的至少一个。
具体的，将电池包的正极外侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输出总正电压信号；将电池包的正极内侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输入总正电压信号；将电池包的负极外侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输出总负电压信号；将电池包的负极内侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输入总负电压信号；将电池包的外壳与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包外壳的电压信号。
S102，根据隔离芯片的输出信号，检测待测系统是否发生打火现象。
根据隔离芯片的特性，隔离芯片的输入信号的电平与输出信号的电平是一致的，因此，本申请根据隔离芯片的输出信号，检测待测系统是否发生打火现象时，若输出信号的电平与隔离芯片的输入信号的电平不一致，就检测到待测系统发生打火现象；或者，若输 出信号的电平与隔离芯片的输入信号的电平一致，就检测到待测系统没有发生打火现象。
具体的，本申请控制隔离芯片的输入电平保持不变，因此，在待测系统没有发生打火现象时，隔离芯片输出信号的电平值与隔离芯片的输入电平保持一致。如此，若待测系统发生了打火现象，则隔离芯片接收到的与待测系统相关的输出信号就会出现较大的变化速率，而当与待测系统相关的输出信号的变化速率大于隔离芯片的共模传输抑制比的典型值时，隔离芯片输出信号的电平值就会出现变化，而不再保持不变。因此，若隔离芯片输出信号的电平与隔离芯片的输入电平不一致，就可以判定待测系统发生打火现象。
可以理解的是，隔离芯片的共模传输抑制比的典型值与隔离芯片的型号有关，例如，Si86XX型号的隔离芯片的共模传输抑制比的典型值为50KV/μs，该隔离芯片可以检测到的最大电压为1500V。
具体的，请参考图4，其为本申请中隔离芯片的输出信号示意图。如图4所示，A信号的电平值保持不变，为正常情况下，即待测系统没有发生打火现象时，控制器接收到的隔离芯片的输出信号。B信号的电平值发生了变化，不再与输入信号的电平保持一致，为待测系统发生打火现象时控制器接收到的隔离芯片的输出信号。
若接收到的隔离芯片的输出信号为如图4所示的A信号，即可检测到待测系统没有发生打火现象；或者，若接收到的隔离芯片的输出信号为如图4所示的B信号，即可检测到待测系统发生了打火现象。如此，通过接收到的隔离芯片输出信号，即可快速高效的确定待测系统是否发生打火现象。
需要说明的是，由于接收到的隔离芯片的输出信号是隔离芯片根据隔离芯片接收到的与待测系统相关的输出信号输出的，因此，根据与待测体统相关的输出信号的不同，接收到的隔离芯片的输出信号也不同。
在一个具体的实现过程中，可以将与待测系统相关的输出信号中的一个与待测系统相关的输出信号作为基准信号，然后，根据其他至少一个与待测系统相关的输出信号相对于该基准信号的变化速 率，输出至少一个隔离芯片的输出信号。具体的，若隔离芯片接收到的与待测系统相关的输出信号的数目为N，N为大于1的整数，则隔离芯片的输出信号的数目可以为[1，N-1]。
以待测系统为电池包为例，若隔离芯片接收到的与待测系统相关的输出信号分别为：电池包的总正电压信号、电池包的总负电压信号和电池包的外壳电压信号。其中，电池包的外壳电压信号可以作为上述基准信号。
隔离芯片可以输出一个输出信号，假设为第一输出信号，则第一输出信号为隔离芯片根据电池包的总正电压信号和电池包的总负电压信号得到的总待测系统输出信号，并根据该总待测系统输出信号相较于电池包的外壳电压信号得到的。如此，根据接收到的第一输出信号，可以检测到待测系统是否发生打火现象。
或者，隔离芯片也可以输出两个输出信号，分别为第二输出信号和第三年输出信号。其中，第二输出信号为隔离芯片根据电池包的总正电压信号相较于电池包的外壳电压信号得到的，第三输出信号为隔离芯片根据电池包的总负电压信号相较于电池包的外壳电压信号得到的。如此，根据接收到的第二输出信号可以检测到第二输出信号对应的电池包的正极是否发生打火现象，根据接收到的第三输出信号可以检测到第三输出信号对应的电池包的负极是否发生打火现象。
因此，本申请提供的打火检测方法，在一定的条件下，可以缩小待测系统发生打火现象的具体范围，更有利于在火灾等事故发生前检测到并消除待测系统的打火隐患，减少了不必要的生命财产损失。
进一步的，本申请中，若检测到待测系统发生打火现象，还可以针对待测系统发生的打火现象进行指定处理。
具体的，本申请中，进行指定处理的实现方式，可以包括但不限于以下两种方式：
第一种：切断待测系统的电路。
第二种：输出报警提示信息。
可以理解的是，上述两种实现方式仅用以说明本方案，并不用以限制本申请。在一个具体的实现过程中，若检测到待测系统发生打火现象，可以根据上述两种方法中的一种方法进行处理，也可以同时使用上述的两种方法进行处理，本申请对此不进行特别限定。
本申请中的一个技术方案具有如下有益效果：
本申请中，在与隔离芯片连接的控制器上，隔离芯片还与待测系统连接，通过接收隔离芯片的输出信号，然后，可以根据隔离芯片的输出信号，检测待测系统是否发生打火现象。本申请中检测待测系统是否发生打火现象时，不需要复杂的电路设计，通过一个隔离芯片和一个控制器即可实现，检测电路简单可靠，能耗较小，且故障率较低；并且，本申请中，利用隔离芯片的输出信号的电平与输入信号的电平一致的特性，控制器只需要对隔离芯片的输出信号进行简单判断，即可检测出待测系统是否发生了打火现象，控制器既不需要对待测系统的电压、电流等参数进行精确采集，也不需要其他复杂的算法和策略，对控制器的要求较低，实现方式简单方便，灵活性较高，且能有效提高检测效率；因此，本申请解决了现有的打火检测技术存在的实现成本较高的问题。
实施例二
本申请给出一种打火检测方法，请参考图5，其为本申请所提供的打火检测方法的第二流程示意图。
如图5所示，该方法包括以下步骤：
S501，接收与待测系统相关的输出信号。
需要说明的是，本申请提供的检测方法执行在与待测系统连接的隔离芯片上。
本申请对隔离芯片的型号和类型不进行特别限定。例如，在一个具体的实现过程中，隔离芯片可以采用Si86XX型号的隔离芯片。
在一个具体的实现过程中，隔离芯片接收到的与待测系统相关的输出信号可以为电压信号。
需要说明的是，本申请中，隔离芯片接收到的与待测系统相关的输出信号的数目为至少两个。
例如，可以在待测系统中选择至少两个不同的位置连接隔离芯片，并向隔离芯片输出这至少两个不同位置上的与待测系统相关的输出信号。与隔离芯片连接的待测系统的具体位置可以根据实际需要进行选择，本申请对此不进行特别限定。
以待测系统为电池包为例进行具体说明。隔离芯片接收到的与待测系统相关的输出信号可以包括但不限于：电池包的总正电压信号、电池包的总负电压信号和电池包的外壳电压信号中的至少两个。其中，可以将电池包外壳的电压信号作为基准信号。
其中，电池包的总正电压信号可以包括但不限于：电池包的输入总正电压信号和电池包的输出总正电压信号中的至少一个。电池包的总负电压信号可以包括但不限于：电池包的输入总负电压信号和电池包的输出总负电压信号中的至少一个。
具体的，将电池包的正极外侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输出总正电压信号；将电池包的正极内侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输入总正电压信号；将电池包的负极外侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输出总负电压信号；将电池包的负极内侧与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包的输入总负电压信号；将电池包的外壳与隔离芯片相连接，隔离芯片接收到的与待测系统相关的输出信号为电池包外壳的电压信号。
S502，根据与待测系统相关的输出信号，检测待测系统是否发生打火现象。
本申请中，根据接收到的与待测系统相关的输出信号，检测待测系统是否发生打火现象时，若输出信号的变化速率达到了预设的速率阈值，就检测到待测系统发生打火现象；或者，若输出信号的变化速率没有达到预设的速率阈值，就检测到待测系统没有发生打火现象。
在一个具体的实现过程中，速率阈值可以预设为隔离芯片的共模传输抑制比的典型值。可以理解的是，隔离芯片的共模传输抑制 比的典型值与隔离芯片的型号有关，例如，Si86XX型号的隔离芯片的共模传输抑制比的典型值为50KV/μs，该隔离芯片可以检测到的最大电压为1500V。
具体的，本申请中，若待测系统发生了打火现象，则隔离芯片接收到的与待测系统相关的输出信号就会出现较大的变化速率，而当与待测系统相关的输出信号的变化速率大于预设的速率阈值时，隔离芯片就可以检测到待测系统发生打火现象。
具体的，本申请中，若隔离芯片接收到的与待测系统相关的输出信号包括第一电压信号和第二电压信号，则可以获得第一电压信号相对于第二电压信号的变化速率，以作为与待测系统相关的输出信号的变化速率。
举例说明，若接收到的第二电压信号保持不变，为10V，在一段时间内接收到的第一电压信号分别为5V、8V、12V、18V、11V，则得到第一信号相较于第二信号的变化值分别为：-5、-2、+2、+8、+1，如此，可以得到如图6所示的A信号类似的与待测系统相关的输出信号示意图。
具体的，请参考图6，其为本申请中与待测系统相关的输出信号的示意图。如图6所示的横线表示第二信号的电压值，为第一信号的基准值，第一信号以第二信号为基准有不同程度的上下波动。因此，获取如图6所示A信号中当前时刻的第一信号相对于第二信号的变化速率，即为当前时刻所对应的曲线的斜率。
在一个具体的实现过程中，如图6所示的A信号为待测系统没有发生打火现象时接收到与待测系统相关的输出信号；如图6所示的B信号为待测系统发生打火现象时接收到的与待测系统相关的输出信号。
在一个具体的实现过程中，若接收到的与待测系统相关的输出信号为如图6所示的A信号，即可检测到待测系统没有发生打火现象；或者，若接收到的与待测系统相关的输出信号为如图6所示的B信号，即可检测到待测系统发生了打火现象。如此，通过接收到的与待测系统相关的输出信号，即可快速高效的确定待测系统是否 发生打火现象。
具体的，本申请中，若检测到待测系统发生打火现象，发送指示信号给控制器，指示信号用以指示控制器进行指定处理。
需要说明的是，根据接收到的与待测系统相关的输出信号的不同，隔离芯片输出的指示信号也是不同的。
在一个具体的实现过程中，可以将与待测系统相关的输出信号中的一个与待测系统相关的输出信号作为基准信号，然后，根据其他至少一个与待测系统相关的输出信号相对于该基准信号的变化速率，检测待测系统是否发生打火现象，并输出指示信号。具体的，若隔离芯片接收到的与待测系统相关的输出信号的数目为N，N为大于1的整数，则隔离芯片输出的指示信号的数目可以为[1，N-1]。
以待测系统为电池包为例，若隔离芯片接收到的与待测系统相关的输出信号分别为：电池包的总正电压信号、电池包的总负电压信号和电池包的外壳电压信号。其中，电池包的外壳电压信号为基准信号。
则隔离芯片可以输出一个指示信号，假设为第一指示信号，则第一指示信号为隔离芯片根据电池包的总正电压信号和电池包的总负电压信号得到的总待测系统输出信号，并根据该总待测系统输出信号相较于电池包的外壳电压信号得到的。如此，根据接收到的第一指示信号，可以检测到待测系统是否发生打火现象，并在检测到待测系统发生打火现象时指示控制器对待测系统进行指定处理。
或者，隔离芯片可以输出两个指示信号，分别为第二指示信号和第三指示信号。其中，第二指示信号为隔离芯片根据电池包的总正电压信号相较于电池包的外壳电压信号得到的，第三指示信号为隔离芯片根据电池包的总负电压信号相较于电池包的外壳电压信号得到的。如此，根据接收到的第二指示信号可以检测到第二指示信号对应的电池包的正极是否发生打火现象，并在检测到电池包的正极发生打火现象时，指示控制器对电池包的正极进行指定处理；同时，根据接收到的第三指示信号可以检测到第三指示信号对应的电池包的负极是否发生打火现象，并在检测到电池包的负极发生打火 现象时，指示控制器对电池包的负极进行指定处理。
因此，本申请提供的打火检测方法，在一定的条件下，可以缩小待测系统发生打火现象的具体范围，更有利于在火灾等事故发生前检测到并消除待测系统的打火隐患，减少了不必要的生命财产损失。
在一个具体的实现过程中，第一电压信号包括待测系统的总正电压信号和待测系统的总负电压信号中至少一个。
在另一个具体的实现过程中，第二电压信号包括待测系统的总正电压信号、待测系统的总负电压信号和与待测系统的外壳的电压信号中至少一个。
需要说明的是，第一信号和第二信号不相同。
本申请对指示信号可以指示控制器对待测系统进行指定处理的实现方式不进行特别限定。
例如，指示信号可以指示控制器对待测系统进行指定处理时，可以包括但不限于以下两种方式：
第一种：切断待测系统的电路。
第二种：输出报警提示信息。
可以理解的是，上述两种实现方式仅用以说明本方案，并不用以限制本申请。在一个具体的实现过程中，若检测到待测系统发生打火现象，可以指示控制器根据上述两种方法中的一种方法进行处理，也可以指示控制器同时使用上述的两种方法进行处理，本申请对此不进行特别限定。
本申请中的一个技术方案具有如下有益效果：
本申请中，在与待测系统连接的隔离芯片上，通过接收与待测系统相关的输出信号，然后，可以根据与待测系统相关的输出信号，检测待测系统是否发生打火现象。本申请中检测待测系统是否发生打火现象时，不需要复杂的电路设计，通过一个隔离芯片即可实现，不再需要其他的额外硬件结构，检测电路简单可靠，能耗较小，且故障率较低；并且，本申请中，隔离芯片只需要获取接收到的输出信号的变化速率，从而，对输出信号的变化速率进行一个简单判断， 即可检测出待测系统是否发生了打火现象，隔离芯片不需要其他复杂的算法和策略，对控制器要求极低，实现方式简单方便，灵活性较高，且能有效提高检测效率；因此，本申请解决了现有的打火检测技术存在的实现成本较高的问题。
