音频设备(如耳机、麦克风等)的插头的规格是不同的，首先，音频设备的尺寸(一般指插头的长度)存在差异，目前，市面上常见的音频设备(如耳机、麦克风等)的插头一般是3.5毫米(mm)的，然而在一些款式较老的音频设备，或者一些非常规领域的设备上使用的音频设备上，仍可能有2.5mm、6.35mm等类型的插头；其次，音频设备的插头的段数也是不同的，有两段、三段或四段的插头，一般的单声道的音频设备为两段式插头，立体声(包含左右声道)的音频设备一般为三段式插头，更进一步的，具有麦克风功能的立体声的音频设备一般为四段式结构，段数的不同也导致了上述提到的插头的尺寸的不同。
而可进行播放和录音等功能的音频处理设备(如手机、电脑、云台、可移动平台等，本申请实施方式以云台为例)一般仅设置有一个接口，且接口仅适配一种类型(两段式、三段式、四段式等)的插头，如云台适配3.5mm的三段式插头，若在这些云台上插入具有2.5mm的二段式插头或6.35mm的四段式插头的音频设备时，云台是无法准确地识别和适配这些音频设备的，而是需要人为选择二段式插头转三段式插头的转接头，或者四段式插头转三段式插头的转接头，才能够实现二段式插头和的四段式插头与云台的适配。
请参阅图1，本申请提供一种音频处理系统1000，音频处理系统1000包括音频设备200和音频处理设备100，音频设备200的插头210可拆卸地插接在音频处理设备100的接 口21内。
请参阅图1和图2，本申请提供一种音频处理设备100，音频处理设备100包括承载装置20和插头检测装置10。承载装置20形成有接口21，接口21用于容纳音频设备200的插头210；插头检测装置10的多个接触端子11设置在接口21内。音频处理设备100包括成像设备、云台、可移动平台(如无人机)中的任意一种。
本申请实施方式中，音频处理设备100为云台。云台用于安装终端(如手机)，手机可与云台连接，手机可进行音频播放并将音频信号传输给云台，云台通过接口21内插接的插头210传输音频信号给音频设备(如耳机)，从而实现音频的播放；或者，音频设备200可进行录音，录音信号通过插头210和接口21的连接，传输给云台，然后由云台传输给手机。当然，云台本身也可具有音频播放功能和录音功能，而无需借助手机实现音频播放和录音。
请参阅图1至图4，本申请提供一种插头检测方法，用于插头检测装置10，插头检测装置10包括多个接触端子11，多个接触端子11设置在接口21内，接口21用于容纳音频设备200的插头210，当插头210插接至接口21，多个接触端子11分别与沿插头210的轴向排列的不同插头部位211接触；插头检测方法包括：
011：向接触端子11施加检测电压，并检测接触端子11的电参数；
所述电参数包括所述接触端子的电性参数，例如，电压，电流，电阻中的一种或者多种参数。其中，不同阻抗特性的插头部位211与接触端子11接触，接触端子11的电参数不同。也就是说，所述电参数的取值，可以根据所述检测电压和与所述接触端子接触的插头部位211的阻抗特性得到的。
012：通过接触端子11获取与接触端子11接触的插头部位211的音频信号，并获取音频信号的音频信号参数；
013：根据电参数和音频信号参数确定插头部位211的信号类型。
本申请提供一种插头检测装置10，插头检测装置10包括检测模块12和多个接触端子11。多个接触端子11设置在接口21内，接口21用于容纳音频设备200的插头210，当插头210插接至接口21，多个接触端子11分别与沿插头210的轴向排列的不同插头部位211接触；检测模块12用于执行步骤011、步骤012和步骤013。即检测模块12用于向接触端子11施加检测电压，并检测接触端子11的电参数，其中，不同阻抗特性的插头部位211与接触端子11接触，接触端子11的电参数不同；通过接触端子11获取与接触端子11接触的插头部位211的音频信号，并获取音频信号的音频信号参数；根据电参数和音频信号参数确定插头部位211的信号类型。
具体的，本申请的插头检测装置10包括多个接触端子11，例如插头检测装置10包括两个接触端子11、三个接触端子11、四个接触端子11等，本申请实施方式中，插头检测 装置10包括四个接触端子11，可用于分别检测四段式插头210的四个不同的插头部位211，当插头210插接至用于容纳插头210的接口21时(如图3所示)，四个接触端子11分别与沿插头210的轴向排列的不同插头部位211接触。四个接触端子11分别为第一接触端子111、第二接触端子112、第三接触端子113和第四接触端子114，插头210插入的方向(如图3中的X方向)即为第一接触端子111至第四接触端子114的排列方向，当插入四段式插头210，第一接触端子111至第四接触端子114分别与四段式插头210的四个不同的插头部位211接触；当插入三段式插头210时，第一接触端子111至第三接触端子113分别与三段式插头210的三个不同的插头部位211接触；当插入二段式插头210时，第一接触端子111至第二接触端子112分别与三段式插头210的二段不同的插头部位211接触。
检测模块12包括电源单元121和参数读取单元122。电源单元121通过给接触端子11施加检测电压(如电源单元121向接触端子11施加偏置电压，电源单元121可以是编译编码器(Codec)的内部输出电源、低压差线性稳压器(low dropout regulator，LDO)电源等直流输出电源)，此时，参数读取单元122可获取到被施加了偏置电压的接触端子11的电参数，电参数可包括电压和电流，可以理解，当给接触端子11施加偏置电压后，即可获取到接触端子11的电压，由于不同的插头部位211中间是存在绝缘环间隔的，接触端子11的电压仅与接触的插头部位211有关。每个插头部位211的功能类型(如作为播放设备、有源麦克风、无源麦克风、接地等)不同，其阻抗特性也是不同的，而阻抗特性的不同，会导致与插头部位211的接触端子11的电压也不同。因此，检测模块12根据接触端子11的电压可初步判断与其接触的插头部位211的功能类型，如功能类型为播放设备、麦克风、接地等。在确定每个插头部位211的功能类型后，即可初步确定插头210的类型。当然，当功能类型为播放设备(麦克风)的插头210的数量为2时，播放设备(麦克风)包含左声道和右声道，左右声道对应的插头部位211的阻抗特性也可能是相同的，检测模块12可根据两者的轴向排列位置确定插头部位211为左声道还是右声道，例如，一般的，左声道和右声道一般沿着插头210插入方向的反方向(即，图3中的X方向的反方向)依次排列，在插头210插入后，左声道更为远离接口21的出口处，检测模块12根据电参数和两者的轴向排列位置可确定插头部位211为左声道还是右声道；或者，在存在两个功能类型均为播放设备的插头部位211时，检测模块12可以其中任一插头部位211作为左声道，而另一插头部位211作为右声道。
由于有时候插入的插头210为非音频设备200、或者已经损坏的音频设备200的插头210时，若阻抗特性与音频设备200的插头210相同，也可能会被误识别为正常音频设备200的插头210，因此，在获取接触端子11的电压时，可同时获取与接触端子11接触的插头部位211的音频信号，音频信号为根据插头部位211的功能类型驱动插头部位211后， 从接触端子11处得到的信号。例如，插头部位211的功能类型为麦克风时，此时以麦克风驱动该插头部位211时，能够得到麦克风音频信号；再例如，插头部位211为播放设备时，此时以播放设备驱动该插头部位211时，能够得到播放音频信号；在插入的插头210为非音频设备200、或者已经损坏的音频设备200的插头210，可能导致麦克风音频信号(播放音频信号)无法得到，或者得到的麦克风音频信号(播放音频信号)与音频设备200正常驱动时得到的麦克风音频信号(播放音频信号)存在较大差异的，例如音频信号的音频信号参数存在较大差异，音频信号参数可包括幅值、频谱等。因此，通过电参数和音频信号参数可准确地确定插头210是否为正常音频设备200的插头210，并确定插头部位211的功能类型，从而准确识别音频设备200的类型。
进一步的，检测模块12根据音频信号参数判断对应的插头部位211的功能类型，例如根据接触端子11的电参数确定插头部位211的功能类型为麦克风，若该接触端子11对应的音频信号参数表征插头部位211的功能类型为麦克风，则可准确地确定该插头部位211的功能类型为麦克风，可提高检测准确性；若该接触端子11对应的音频信号参数表征插头部位211的功能类型为播放设备，则说明以该接触端子11的电参数确定的插头部位211的功能类型可能存在错误，可以音频信号参数表征的插头部位211的功能类型为插头部位211的最终功能类型，或者重新获取插头部位211对应的电参数和音频信号参数，再次判断插头部位211的功能类型，提高插头部位211的功能类型检测准确性。
检测模块根据电参数和音频信号参数可确定插头部位的信号类型，信号类型可表征插头部位211的功能类型，例如，信号类型为与接触端子11及该接触端子11的功能类型对应的信号，使用5位二进制表示，如第一接触端子111至第四接触端子114使用5位二进制中的前2位进行表示，第一接触端子111对应“00”，第二接触端子112对应“01”，第三接触端子113对应“10”，第四接触端子114对应“11”；功能类型与5位二进制中的后3位进行表示，左声道播放设备对应“001”，右声道播放设备对应“010”，接地对应“011”，无源麦克风对应“100”，有源麦克风对应“101”。
如三段式立体声耳机，则其信号类型为“00001”(表示第一接触端子111的功能类型为左声道播放设备)，“01010”(表示第二接触端子112的功能类型为右声道播放设备)，“10011”(表示第三接触端子111的功能类型为接地)。如此，根据信号类型能够快速得到每个接触端子11对应的插头部位211的功能类型。
然后根据插头部位211的功能类型即可确定音频设备200的类型。例如，四个接触端子11识别到的对应的插头部位211的功能类型分别为左声道播放设备、右声道播放设备、接地和无源麦克风，则音频设备200的类型为四段式立体声带无源麦克风的耳机；再例如，三个接触端子11识别到的对应的插头部位211的功能类型分别为左声道、右声道和接地， 则表示音频设备200的类型为三段式立体声耳机。
本申请插头检测方法、插头检测装置10、音频处理设备100和音频处理系统1000中，根据接触端子11接触的音频设备200的插头210的不同插头部位211的阻抗特性的不同，接触端子11的电参数也不同的特性，及能够表征插头部位211是否为正常音频设备200的音频信号参数共同确定信号类型，信号类型可表征插头部位211的功能类型，从而确定音频设备200的类型。另外，由于插头检测装置10设置有多个分别与沿插头210的轴向排列的不同插头部位211接触的接触端子11，通过选择性的控制对应的接触端子11和插头部位211的连接的通断，无需使用转接头，即可实现一个接口21适配具有不同类型的插头210的多种音频设备200。
请参阅图2和图5，在某些实施方式中，插头检测方法还包括：
014：依据信号类型，确定用于传输信号的插头部位211的数量；及
015：依据用于传输信号的插头部位211的数量确定音频设备200的第一信息。
在某些实施方式中，检测模块12还用于执行步骤014和步骤015。即，检测模块12还用于依据信号类型，确定用于传输信号的插头部位211的数量；及依据用于传输信号的插头部位211的数量确定音频设备200的第一信息。
具体地，用于传输信号的插头部位211的功能类型一般包括播放设备、有源麦克风、无源麦克风、接地等，也即是说，能被检测模块12识别出功能类型的插头部位211一般是能够传输信号的。在检测模块12根据插头部位211的电参数和音频信号参数确定信号类型后，检测模块12可根据识别出功能类型的信号类型的数量，确定用于传输信号的插头部位211的数量，从而根据用于传输信号的插头部位211的数量确定音频设备200的第一信息，第一信息可包括音频设备200的段数，可以理解，音频设备200的段数可等于用于传输信号的插头部位211的数量。当然，音频设备200的段数还可大于用于传输信号的插头部位211的数量，由于插头检测装置10检测出的最大段数等于接触端子11的数量，当音频设备200的段数大于接触端子11的数量时，如为五段式插头，此时音频设备200的段数被检测的段数为4，但实际段数为5。
请参阅图2和图6，在某些实施方式中，插头检测方法还包括：
016：依据信号类型，确定用于传输麦克风信号的插头部位211的数量；及
017：依据用于传输麦克风信号的插头部位211的数量，确定音频设备200的第二信息。
在某些实施方式中，检测模块12还用于执行步骤016和步骤017。即，检测模块12还用于依据信号类型，确定用于传输麦克风信号的插头部位211的数量；及依据用于传输麦克风信号的插头部位211的数量，确定音频设备200的第二信息。
具体地，当检测模块12根据插头部位211的电参数和音频信号参数确定信号类型后， 插头部位211的功能类型就确定了，其中，功能类型为麦克风的插头部位211即为用于传输麦克风信号的插头部位211。可以理解，麦克风也可以分为左声道麦克风和右声道麦克风，从单纯的阻抗特性来看，两者可能差异较小，当功能类型为麦克风的插头部位211的数量为两个时，即可确定当前的麦克风为双声道麦克风(即，包括左声道麦克风和右声道麦克风)，当根据功能类型为麦克风的插头部位211的数量为三个时，即可确定当前的麦克风为三声道麦克风等；从而根据用于传输麦克风信号的插头部位211的数量确定音频设备200的第二信息，第二信息可包括音频设备200是否具有麦克风功能，如当用于传输麦克风信号的插头部位211的数量大于或等于1时，即认为音频设备200是具有麦克风功能；第二信息还可包括音频设备200的麦克风类型，如单声道麦克风、双声道麦克风、三声道麦克风等。
请参阅图2和图7，在某些实施方式中，插头检测方法还包括：
018：若存在用于传输麦克风信号的插头部位211，则确定音频设备200具有麦克风功能；
019：依据信号类型，判断用于传输麦克风信号的插头部位211是否向接触端子11施加电流；及
020：依据判断结果，确定音频设备200的第三信息。
在某些实施方式中，检测模块12还用于执行步骤018、步骤019和步骤020。即，检测模块12还用于在存在用于传输麦克风信号的插头部位211时，则确定音频设备200具有麦克风功能；依据信号类型，判断用于传输麦克风信号的插头部位211是否向接触端子11施加电流；及依据判断结果，确定音频设备200的第三信息。
具体地，在根据用于传输麦克风信号的插头部位211的数量确定音频设备200具有麦克风功能后，可进一步判断音频设备200的麦克风类型，可以理解，除了根据用于传输麦克风信号的插头部位211的数量确定的麦克风的声道数量外，麦克风还存在有源麦克风和无源麦克风的区别，有源麦克风即为音频设备200设置有电源为该音频设备200供电，而无源麦克风则使用云台的接口21进行供电，音频设备200中插头部位211的功能类型还包括有源麦克风和无源麦克风，有源麦克风和无源麦克风对应的插头部位211阻抗特性不同，根据接触端子11的电压可判断插头部位211为有源麦克风还是无源麦克风，另外由于有源麦克风由音频设备200供电，在获取有源麦克风对应的接触端子11的电压时，可同时获取该接触端子11处的电流，判断是否接收外部电源输入的电流，依据判断结果，可确定音频设备200的第三信息，第三信息可包括音频设备200的麦克风是否有源，例如若用于传输麦克风信号的插头部位211向接触端子11施加了电流，则该插头部位211的功能类型为有源麦克风，若用于传输麦克风信号的插头部位211未向接触端子11施加了电流，则插头部 位211的功能类型为无源麦克风，从而根据判断结果确定用于传输麦克风信号的插头部位211是否有源，以进一步麦克风的功能类型，提高检测准确性。
请参阅图2和图8，在某些实施方式中，步骤011包括：
0111：向多个接触端子11中的部分施加检测电压，并检测施加检测电压的接触端子11的电参数。
在某些实施方式中，检测模块12还用于执行步骤0111。即，检测模块12还用于向多个接触端子11中的部分施加检测电压，并检测施加检测电压的接触端子11的电参数。
具体地，电源单元121单元用于向接触端子11施加检测电压，例如，电源单元121用于向多个接触端子11中的部分施加检测电压，该部分的数量小于或接触端子11的数量，如电源单元121用于向多个接触端子11中的一个施加检测电压，参数读取单元122用于读取施加了检测电压的接触端子11的电参数，如此，电源单元121可依次向多个接触端子11施加检测电压，从而使得参数读取单元122依次获取施加了检测电压的接触端子11的电参数；或者，电源单元121用于向多个接触端子11中的两个或三个施加检测电压，参数读取单元122用于读取施加了检测电压的接触端子11的电参数；如此，每次只需向部分接触端子11施加检测电压，且只需获取该部分接触端子11的电参数，电路设计较为简单。
在其他实施方式中，电源单元121向所有接触端子11均施加检测电压，参数读取单元122用于读取施加了检测电压的接触端子11的电参数，从而基本同时完成所有接触端子11的电参数的获取，有利于提高检测效率。
请参阅图2和图9，在某些实施方式中，接触端子11包括目标接触端子11，插头检测方法还包括：
021：依据信号类型，通过目标接触端子11驱动音频设备200。
在某些实施方式中，插头检测装置10还包括驱动模块13，驱动模块13用于执行步骤021。即，驱动模块13用于依据信号类型，通过目标接触端子11驱动音频设备200。
具体地，根据音频设备200的插头210的插头部位211的功能类型，可确定用于实现音频设备200功能的目标接触端子11，目标接触端子11为用于实现对应的插头部位211的功能的接触端子11，驱动模块13可选择性的控制对应的目标接触端子11和插头部位211的连接的通断，从而无需使用转接头，实现一个接口21适配多种具有不同类型插头210的音频设备200，也即是说，接触端子11不仅可实现对应的插头部位211的识别，还能够用于实现插头部位211的功能，例如第一接触端子111对应的插头部位211的功能类型为麦克风，若要实现麦克风功能，则目标接触端子为第一接触端子111，音频设备200获取的麦克风音频信号可通过插头部位211对应的第一接触端子111传输给云台，再例如，第二接触端子112对应的插头部位211的功能类型为播放设备，若要实现音频播放功能，则目标 接触端子为第二接触端子112，若要同时实现麦克风功能和音频播放功能，则目标接触端子为第一接触端子111和第二接触端子112，以实现音频播放功能为例，云台将播放音频信号通过第二接触端子112传输给对应的插头部位211，从而通过音频设备200播放音频。如此，通过选择性的控制对应的目标接触端子11和插头部位211的连接的通断，无需使用转接头，即可实现一个接口21适配具有不同类型的插头210的多种音频设备200。
请参阅图2和图10，在某些实施方式中，接触端子11包括插入接触端子115，插头检测方法还包括：
022：依据插入接触端子115的电参数，检测是否有插头210插接至接口21。
在某些实施方式中，接触端子11包括插入接触端子115，检测模块12还用于执行步骤022。即，检测模块12还用于依据插入接触端子115的电参数，检测是否有插头210插接至接口21。
具体地，请参阅图2，可以理解，在插头210插入接口21后，即使最短的两段式插头210也能够顶开第三接触端子113和第四接触端子114，因此，在初始状态(未插入插头210的状态)时，插入接触端子115可与第三接触端子113或第四接触端子114接触的，从而保证任意类型的插头21插入后均可以被检测到。本实施方式以插入接触端子115与第三接触端子113接触为例进行说明，插入接触端子115与第四接触端子114接触时的检测原理基本类似，在此不再赘述。
请参阅图3，在插头210插入接口21后，第三接触端子113与插入接触端子115的接触断开，参数读取单元122在第三接触端子113与插入接触端子115接触和断开时，从插入接触端子115处接收的电参数是不同的，因此，根据插入接触端子115处的电参数可准确地判断是否有插头210插接至接口21。例如，电参数包括电压，第三接触端子113与插入接触端子115接触时，电压为电源单元121的电压，而第三接触端子113与插入接触端子115断开时，电压为0，从而根据插入接触端子115的电压判断是否有插头210插接至接口21。
在其他实施方式中，多个接触端子11中的任一个(如第三接触端子113或第四接触端子114)作为插入接触端子115，插入接触端子115除了可识别对应的插头部位211的功能类型外，还可以进行插入检测，只要任一插头210插入接口21内，就会与该插入接触端子115接触，从而可根据插入接触端子115的电参数检测是否有插头210插入接口21。
请参阅图2和图11，在某些实施方式中，步骤012包括：
0121：基于电参数确定与接触端子11接触的插头部位211的功能类型信息；
0122：根据功能类型信息，通过接触端子11获取与接触端子11接触的插头部位211的音频信号。
在某些实施方式中，检测模块12还用于执行步骤0121和步骤0122。即，检测模块12还用于基于电参数确定与接触端子11接触的插头部位211的功能类型信息；根据功能类型信息，通过接触端子11获取与接触端子11接触的插头部位211的音频信号。
具体地，在获取音频信号时，先基于插头部位211对应的接触端子11的电参数确定该插头部位211的功能类型信息，功能类型信息包括播放设备、麦克风、接地等，功能类型信息用于表征对应的插头部位211的功能，如功能类型信息为播放设备，则插头部位211的功能为播放音频；功能类型信息为麦克风，则插头部位211的功能为录音功能。然后驱动模块13根据插头部位211的功能类型驱动插头部位211实现对应的功能，例如，插头部位211的功能类型为麦克风时，此时以麦克风驱动该插头部位211时，能够得到麦克风音频信号；再例如，插头部位211为播放设备时，此时以播放设备驱动该插头部位211时，能够得到播放音频信号；
参数读取单元121可根据插头部位211的功能类型，通过接触端子11获取与接触端子11接触的插头部位211的音频信号。例如，参数读取单元122包括针对不同音频信号的处理单元，如针对播放音频信号的播放处理单元，针对麦克风音频信号的麦克风处理单元。参数读取单元122通过确定插头部位211的功能类型，即可调用与功能类型对应的处理单元进行处理，从而根据处理单元的处理结果进一步判断功能类型是否判断有误，例如，当播放处理单元处理麦克风音频信号的音频信号参数时，由于播放处理单元仅与播放音频信号适配，会无法产生正常的处理结果并报错，从而确定根据插头部位211的对应的电参数确定的功能类型是否有误，提高检测准确性。
另外，在插入的插头210为非音频设备200、或者已经损坏的音频设备200的插头210，可能导致麦克风音频信号(播放音频信号)无法得到，或者得到的麦克风音频信号(播放音频信号)与音频设备200正常驱动时得到的麦克风音频信号(播放音频信号)是存在较大差异的，处理单元通过对音频信号的音频信号参数的提取即可获取判断结果，判断结果包括功能类型为播放设备或麦克风，或者无法获取功能类型等，其中，无法获取功能类型的判断结果即表示插入的插头210为非音频设备200、或者已经损坏的音频设备200的插头210。
请参阅图2，在一个具体的例子中，接触端子11的数量为四，分别为第一接触端子111至第四接触端子114，可检测目前市面上最大的四段式接口21的音频设备200的类型，参数读取单元122可为每个接触端子11设置一个参数读取接口123，本实施方式以非国际标准的音频设备200的插头210为例，由于非国际标准的音频设备200必然存在功能类型为接地的插头部位211，例如三段式或四段式耳机插头210中接地的插头部位211一般与第二接触端子112接触，接地的插头部位211的电压一般为0V，故无需设置与第二接触端子112 对应的参数读取接口123去读取第二接触端子112的电压，只需使得第二接触端子112接地即可，默认第二接触端子112的电压为0V。因此，参数读取单元122设置有第一参数读取接口1231、第二参数读取接口1232和第三参数读取接口1233，分别读取第一接触端子111的电参数和音频信号、第二接触端子112的电参数和音频信号、及第三接触端子113的电参数和音频信号。插头部位211的阻抗和对应的音频设备的类型的关系如表1。
Figure PCTCN2020117456-appb-000001
表1
从表1中可以看出，当阻抗为0欧姆(Ω)，表示该接触端子11未与插头部位211接触或者接触端子11与功能类型为接地的插头部位211接触、当阻抗位于16Ω到100Ω时，表示该接触端子11与插头部位211接触且插头部位211的功能类型为播放设备、当阻抗位于500Ω到2000Ω时，表示该接触端子11与插头部位211接触且插头部位211的功能类型为无源麦克风、当阻抗位于10000Ω以上时，表示该接触端子11与插头部位211接触且插头部位211的功能类型为有源麦克风、当阻抗接近无穷大时，表示该接触端子11与插头部位211接触但插头部位211无任何功能，仅起到增加插头210长度的作用(下称绝缘插头部位211)。
可以理解，不同的阻抗，参数读取接口123读取的电参数(以电压为例)是不同的，例如当阻抗为0Ω时，该接触端子11对应的电压范围为[0，V1]，即此时接触端子11对应的插头部位211不存在或者接地；当阻抗位于16Ω到100Ω时，该接触端子11对应的电压范围为[V2，V3]，即此时接触端子11对应的插头部位211为播放设备；当阻抗位于500Ω到2000Ω时，该接触端子11对应的电压范围为[V4，V5]，即此时接触端子11对应的插头 部位211为无源麦克风；当阻抗位于10000Ω以上时，该接触端子11对应的电压范围为[V6，V7]，即此时接触端子11对应的插头部位211为有源麦克风；当阻抗接近无穷大时，该接触端子11对应的电压范围等于电源单元121的偏置电压V8，即此时接触端子11对应的插头部位211为绝缘插头部位211；其中，由于电阻范围的增加，接触端子11被分配的电压就越大，V1至V8依次增大并可根据电源单元121的输出的偏置电压确定，且[0，V1]、[V2，V3]、[V4，V5]、和[V6，V7]没有交集。
请参阅图2，检测模块12包括多个第一控制开关124和第二控制开关125，控制开关可以是软件逻辑上的控制开关，也可以是实体电路的控制开关。
多个第一控制开关124分别控制参数读取接口123与对应的接触端子11的通断，在控制第一控制开关124闭合时，参数读取接口123用于从第一控制开关124对应的接触端子11处读取电参数及音频参数。另外，由于第二接触端子112仅可能接触接地的插头部位211或者不与任一插头部位211接触，第二接触端子112的电参数和音频参数均无需获取。
多个第二控制开关125分别控制电源单元121及驱动模块13、与对应的接触端子11的通断，在控制第二控制开关125闭合时，电源单元121向控制开关对应的接触端子11输出偏置电压V8，驱动模块13此时也可驱动对应的接触端子11和插头部位211，从而实现该插头部位211的功能。
第二控制开关125的数量为3个，分别为SW1、SW2和SW3，分别用于控制是否获取第一接触端子111、第三接触端子113和第四接触端子114的电参数和音频参数。
第二控制开关125的数量为5个，分别为S4、S5、S6、S7和S8，其中2个用于控制电源单元121与第四接触端子114的通断(如图2中的SW4和SW7)，可保证其中一个第二控制开关125损坏时，通过另一个第二控制开关125也能够实现电源单元121与第四接触端子114的通断控制，剩余3个分别用于控制电源单元121与第一接触端子111、第二接触端子112和第三接触端子113的通断，如图2所示，SW5控制电源单元121与第一接触端子111的通断、SW6控制电源单元121与第三接触端子113的通断、SW4和SW7均可单独控制电源单元121与第四接触端子114的通断。
请参阅图3，在音频设备200的插头210插入云台的接口21时，第三接触端子113被插头210顶起，以使得第三接触端子113与插入接触端子115的连接断开，参数读取单元122设置有插入检测接口1234，通过插入检测接口1234获取插入接触端子115的电参数，由于接触端子113与插入接触端子115的连接和断开时获取的电参数是不同的，从而根据插入接触端子115的电参数判断是否有插头210插入接口21。
请参阅图12，在确定有插头210插入接口21后，开始检测音频设备200的类型，此时插头检测装置10先控制SW1和SW5导通，电源单元121向对应的接触端子11施加偏 置电压，以检测第一接触端子111是否接触插头部位211并确定插头部位211的类型，对于非国际标准的音频设备200的插头210，第一接触端子111对应的插头部位211仅可能为不存在或者为麦克风。
当第一接触端子111的电压U1位于[0，V1]时，可确定第一接触端子111对应的插头部位211不存在，当前音频设备200的插头210为两段式或者三段式插头210。检测模块12将SW1和SW5断开以进行下一步检测，控制SW3和SW4导通，以检测第四接触端子114接触的插头部位211的类型。
当第四接触端子114的电压U4位于[V2，V3]时，可确定第四接触端子114对应的插头部位211的功能类型为播放设备，进一步检测第三接触端子113接触的插头部位211的类型，此时断开SW3和SW4，导通SW2和SW6，当第三接触端子113的电压U3位于[0，V1]时，可确定第三接触端子113对应的插头部位211的功能类型为接地，而三段式插头210的接地一般与第二接触端子112接触，因此，基本可确定音频设备200的类型为两段式单声道耳机；当第三接触端子113的电压U3位于[V2，V3]时，可确定第三接触端子113对应的插头部位211的功能类型为播放设备，而三段式插头210的接地一般与第二接触端子112接触，因此，基本可确定音频设备200的类型为三段式立体声耳机；当第三接触端子113的电压U3等于V8时(第三接触端子113的电压U3等于V8指的是第三接触端子113的电压U3与V8的值的差值小于预定差值)，可确定第三接触端子113对应的插头部位211的功能类型为绝缘插头部位211，而三段式插头210的接地一般与第二接触端子112接触，因此，基本可确定音频设备200的类型为三段式单声道耳机。
请参阅图13，当第四接触端子114的电压U4位于[V4，V5]时，可确定第四接触端子114对应的插头部位211的功能类型为无源麦克风，此时若第三接触端子113的电压U3位于[0，V1]，则可确定音频设备200的类型为两段式单声道无源麦克风；此时若第三接触端子113的电压U3位于[V4，V5]，可确定第三接触端子113对应的插头部位211的功能类型为无源麦克风，则可确定音频设备200的类型为三段式双声道无源麦克风；此时若第三接触端子113的电压U3位于[V6，V7]，可确定第三接触端子113对应的插头部位211的功能类型为有源麦克风，则可确定音频设备200的类型为三段式双声道有源麦克风，一般的，第四接触端子114对应左声道，第三接触端子113对应右声道，故左声道和右声道分别为无源麦克风和有源麦克风；此时若第三接触端子113的电压U3等于V8，可确定第三接触端子113对应的插头部位211为绝缘插头部位211，则可确定音频设备200的类型为三段式单声道无源麦克风。
请参阅图14，当第四接触端子114的电压U4位于[V6，V7]时，可确定第四接触端子114对应的插头部位211的功能类型为有源麦克风，此时若第三接触端子113的电压U3位 于[0，V1]，则可确定音频设备200的类型为两段式单声道有源麦克风；此时若第三接触端子113的电压U3位于[V4，V5]，可确定第三接触端子113对应的插头部位211的功能类型为无源麦克风，则可确定音频设备200的类型为三段式双声道麦克风，左声道和右声道分别为有源麦克风和无源麦克风；此时若第三接触端子113的电压U3位于[V6，V7]，可确定第三接触端子113对应的插头部位211的功能类型为有源麦克风，则可确定音频设备200的类型为三段式双声道有源麦克风；此时若第三接触端子113的电压U3等于V8，可确定第三接触端子113对应的插头部位211为绝缘插头部位211，则可确定音频设备200的类型为三段式单声道有源麦克风。
请参阅图15，当第一接触端子111的电压U1位于[V4，V5]时，可确定第一接触端子111接触的插头部位211为无源麦克风，当前音频设备200的插头210为四段式插头210。检测模块12将SW1和SW5断开以进行下一步检测，控制SW3和SW4导通，电源单元121向对应的接触端子11施加偏置电压，以检测第四接触端子114接触的插头部位211的类型，可以理解，非国际标准插头210的四段式插头210中，第二接触端子112对应的插头210类型为接地，由于第一接触端子111已经是无源麦克风，因此，只需判断第四接触端子114对应的插头部位211为播放设备或绝缘插头部位211即可。
当第四接触端子114的电压U4位于[V2，V3]时，可确定第四接触端子114对应的插头部位211的功能类型为播放设备，进一步检测第三接触端子113接触的插头部位211的类型，此时断开SW3和SW4，导通SW2和SW6，同样的，只需判断第三接触端子113对应的插头部位211为播放设备或绝缘插头部位211即可。此时若第三接触端子113的电压U3位于[V2，V3]时，可确定第三接触端子113对应的插头部位211的功能类型为播放设备，因此，基本可确定音频设备200的类型为四段式立体声带无源麦克风耳机；当第三接触端子113的电压U3等于V8时，可确定第三接触端子113对应的插头部位211的功能类型为绝缘插头部位211，因此，基本可确定音频设备200的类型为四段式单声道带无源麦克风耳机。
请参阅图16，当第四接触端子114的电压U4等于V8(第四接触端子114的电压U4等于V8指的是第四接触端子114的电压U4与V8的值的差值小于预定差值)时，可确定第四接触端子114对应的插头部位211的功能类型为绝缘插头部位211，进一步检测第三接触端子113接触的插头部位211的类型，此时断开SW3和SW4，导通SW2和SW6，同样的，只需判断第三接触端子113对应的插头部位211为播放设备或绝缘插头部位211即可。此时若第三接触端子113的电压U3位于[V2，V3]时，可确定第三接触端子113对应的插头部位211的功能类型为播放设备，因此，基本可确定音频设备200的类型为四段式单声道带无源麦克风耳机；当第三接触端子113的电压U3等于V8时，可确定第三接触端子113 对应的插头部位211的功能类型为绝缘插头部位211，因此，基本可确定音频设备200的类型为四段式无源麦克风。
请参阅图17，当第一接触端子111的电压U1位于[V6，V7]时，可确定第一接触端子111接触的插头部位211为有源麦克风，当前音频设备200的插头210为四段式插头210。检测模块12将SW1和SW5断开以进行下一步检测，控制SW3和SW4导通，以检测第四接触端子114接触的插头部位211的类型。
当第四接触端子114的电压U4位于[V2，V3]时，可确定第四接触端子114对应的插头部位211的功能类型为播放设备，进一步检测第三接触端子113接触的插头部位211的类型，此时断开SW3和SW4，导通SW2和SW6，同样的，只需判断第三接触端子113对应的插头部位211为播放设备或绝缘插头部位211即可。此时若第三接触端子113的电压U3位于[V2，V3]时，可确定第三接触端子113对应的插头部位211的功能类型为播放设备，因此，基本可确定音频设备200的类型为四段式立体声带有源麦克风耳机；当第三接触端子113的电压U3等于V8时，可确定第三接触端子113对应的插头部位211的功能类型为绝缘插头部位211，因此，基本可确定音频设备200的类型为四段式单声道带有源麦克风耳机。
请参阅图18，当第四接触端子114的电压U4等于V8时，可确定第四接触端子114对应的插头部位211的功能类型为绝缘插头部位211，进一步检测第三接触端子113接触的插头部位211的类型，此时断开SW3和SW4，导通SW2和SW6，同样的，只需判断第三接触端子113对应的插头部位211为播放设备或绝缘插头部位211即可。此时若第三接触端子113的电压U3位于[V2，V3]时，可确定第三接触端子113对应的插头部位211的功能类型为播放设备，因此，基本可确定音频设备200的类型为四段式单声道带有源麦克风耳机；当第三接触端子113的电压U3等于V8时，可确定第三接触端子113对应的插头部位211的功能类型为绝缘插头部位211，因此，基本可确定音频设备200的类型为四段式有源麦克风。
如此，通过上述流程，可快速检测非国际标准的音频设备200的类型，结合非国际标准的音频设备200的特点，省去了无需进行检测部分(如第二接触端子112对应的插头部位211的类型等)，并通过第一接触端子111的电参数确定插头210的段数区间，然后通过段数区间对应的检测流程进行检测，从而无需对所有段数的音频设备200均进行检测，可提高检测效率。
在根据接触端子11的电参数初步确定了音频设备200的类型后，驱动模块13控制对应的控制开关的通断以驱动音频设备200，并获取驱动音频设备200后从接触端子11处获取的音频信号，从而得到音频信号参数，以判断根据电参数确定的接触端子11对应的插头 部位211的功能类型与音频信号参数确定的对应的插头部位211的功能类型是否匹配，进一步保证插头部位211的功能类型的检测准确性。且音频信号参数还可用于判断接触端子11对应的插头部位211是否为非音频设备200或者已经损坏的音频设备200的插头部位211。
例如，请参阅图3和图19，检测模块12根据接触端子11的电参数初步确定了待检测音频设备200的类型为两段式单声道耳机，则驱动模块13控制SW3和SW7导通，以驱动第四接触端子114接触的插头部位211将音频信号传输到音频设备200进行播放，第三参数读取接口1233读取第四接触端子114处的音频信号，并传输给播放处理单元处理，从而确定是否接收到音频信号或根据音频信号的音频信号参数确定该音频信号是否为播放音频信号。例如，若音频信号为播放音频信号，则可进一步确定第四接触端子114对应的插头部位211为播放设备，待检测音频设备200为两段式单声道耳机；若音频信号不是播放音频信号，则可能根据接触端子11的电参数初步确定的音频设备200的类型存在错误，需再次进行电参数的检测；若无法获取到该音频信号，则待检测音频设备200为非音频设备200或损坏的两段式单声道耳机。
如此，通过电参数和音频信号参数确定的插头部位211的信号类型，可更为准确地判断待检测音频设备200的类型，并避免非音频设备200和损坏的音频设备200对检测结果的干扰。
