下面通过结合一个具体的实施例对主控板根据第一电压信号确定锁具状态的具体原理进行说明：
可以选取第一电阻作为第一负载12，选取旋转式电位器作为变阻器11，并且，可以假设第一电阻的阻值为2000Ω。
在锁具处于加锁状态下时，旋转式电位器的阻值为1000Ω，变阻器11的第一固定端与第一负载12的第二端承载的第一电压为3.3V，可见，此时，旋转式电位器上的压降为1.1V，而第一电阻上的压降为2.2V。
而当锁具从加锁状态切换至开锁状态的过程中，驱动电机20发生转动，从而带动旋转式电位器的转动端也发生转动，此时，以旋转式电位器的电阻随着转动后变大为例，当锁芯到达最大位置时，驱动电机20停止转动，假设旋转式电位器增大后的阻值为4000Ω，则此时，旋转式电位器上的压降为2.2V，而第一电阻上的压降为1.1V。其中，锁芯所到达的最大位置可以理解为锁芯所能够到达的极限位置，例如，可以是锁具处于开锁状态时锁芯所位于的第一位置，或者还可以是锁具处于加锁状态时锁芯所位于的第二位置。
可见，通过主控板根据获取到的第一电压信号不同的数值与每个状态下标定的预设数值进行比较，即可确定锁具状态。
图3为实施例一中一种可能的电压状态示意图，如图3所示，在本实施例中可以通过监测变阻器11的第一固定端与动触端之间电压的变化，来确定锁具状态。当锁具状态为加锁状态时，旋转式电位器上的压降为1.1V，而当锁具从加锁状态切换至开锁状态的过程中，旋转式电位器上的压降逐渐上升，直至锁芯到达最大位置时，驱动电机20停止转动，锁具处于开锁状态时，旋转式电位器上的压降为2.2V。可见，通过主控板根据获取变阻器11第一固定端与动触端111之间的第一电压信号不同的数值与每个状态下标定的预设数值进行比较，即可确定锁具状态。
此外，由于主控板上的处理器需要将模拟信号转化为数字信号进行处理，因此，可以通过模数转化器来对获取到的第一电压信号进行处理，即将第一电压信号转化为第一数字信号，并将第一数字信号输入至主控板的第一端口。
具体地，在一种可能的设置方式中，当锁芯位于第一位置时，第一电压信号为第一数值，则此时，根据第一数值进行模数转化后的第一数字信 号为高电平，则确定锁具状态为开锁状态；当锁芯位于第二位置时，第一电压信号为第二数值，则此时，根据第二数值进行模数转化后的第一数字信号为低电平，则确定锁具状态为加锁状态。
而在另一种可能的设置方式中，还可以是当锁芯位于第一位置时，第一电压信号为第一数值，则此时，根据第一数值进行模数转化后的第一数字信号为低电平，则确定锁具状态为开锁状态；当锁芯位于第二位置时，第一电压信号为第二数值，则此时，根据第一数值进行模数转化后的第一数字信号为高电平，则确定锁具状态为加锁状态。
在本实施例中，通过将变阻器的接入电路部分与第一负载进行串联，然后在变阻器的接入电路部分与第一负载上加载稳定的第一电压，并将变阻器的动触端与锁具中的驱动电机的输出轴进行连接，从而使得当锁具在利用驱动电机进行开关操作时，也会同时带动变阻器接入电路的部分的阻值发生变化，进而使得变阻器的第一固定端与动触端之间或者第一负载的两端之间的第一电压信号发生变化，并将第一电压信号发送至锁具上的主控板，从而使得主控板根据当前第一电压信号对应不同的数值与每个状态下标定的预设数值进行比较，以实现锁具状态的确定，通过这种驱动电机转动与变阻器阻值之间的强耦合联动关系，只增加了简单的器件就可以实现锁具状态准确的监测，并可以适配不同的类型的锁具，从而大大降低了锁具的开发和生产成本。
值得说明地，对于本实施例提供的锁具状态监测装置可以是一集成模块，在锁具的设计过程中，可以通过设置相应的安装位置以及电路连接接口，然后将锁具状态监测装置安装至锁具中，使得锁具状态监测装置与控制器、驱动电机以及供电电源相连接，此外，本实施例提供的状态监测装置还可以是应用于普通智能锁的改造，通过将本实施例提供的状态监测装置外设在普通智能锁之外，并建立普通智能锁的锁芯与变阻器动触端之间的运动副连接，即可实现外置状态监测装置对普通智能锁的状态监测。
在图1所示实施例的基础上，图4为本发明实施例三提供的锁具状态监测装置的结构示意图。如图4所示，本实施例提供的锁具状态监测装置，还包括：第二负载30。
其中，第二负载30的第一端用于与驱动电机20的第一输入端连接，以使驱动输出电流经第二负载30之后对驱动电机20进行驱动。值得理解 地，当驱动电机20不工作时，其驱动输出电流为0，而当主控板控制驱动电机20进行转动且处于锁具不同状态切换过程中时，驱动输出电流即为驱动电机20的正常工作电流，而当锁芯转动至卡位时，无论是开锁状态卡位还是加锁状态卡位，此时，驱动电机20所受到的阻力就会加大，则驱动电机20所需的功率也就自然加大，进而使得此时的驱动输出电流迅速提升，从而使得第二负载30两端的压降升高，并且，第二负载30的两端用于与主控板连接，以向主控板输出第二电压信号，以使主控板根据第二电压信号确定锁具是否达到卡位。
下面通过结合一个具体的实施例对主控板根据第二电压信号确定锁具是否达到卡位的具体原理进行说明：
可以选取第二电阻作为第二负载30，并假设第二电阻的阻值为10Ω。
图5为实施例三中一种可能的电压状态示意图。如图5所示，在锁具静止处于加锁状态下或者开锁状态下时，驱动电机20不工作时，其驱动输出电流为0，对应地，此时第二负载30两端的压降也为0V。
当主控板控制驱动电机20运动进行锁具状态切换时，例如，从开锁状态切换至加锁状态，此时，驱动电机20开始转动，可以假设此时驱动电机20的正常工作电流为20mA，即驱动输出电流为20mA，对应地，此时第二负载30两端的压降也为200mV。而当驱动电机20继续转动，直至锁芯运动到极限位置，即锁具到达了卡位位置时，此时驱动电机20所受到的阻力就会加大，则驱动电机20所需的功率也就自然加大，进而使得此时的驱动输出电流迅速提升，例如，升高至200mA，进而使得第二负载30两端的压降升高至2V，在获取到第二负载30的两端的第二电压信号之后，还可以将获取到的第二电压信号与每个状态下标定的预设电压数值进行比较，即可确定锁具总成的卡位状态，其中，上述卡位状态包括：到达卡位状态以及未到达卡位状态。
由于主控板上的处理器需要将模拟信号转化为数字信号进行处理，因此，可以通过模数转化器来对获取到的第二电压信号进行处理，即根据第二电压信号生成第二数字信号，并将第二数字信号输入至主控板的第二端口。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的倍数来确定卡位状态的话，则当倍数大于预设倍数时，模数转化后的第 二数字信号为高电平，可以确定卡位状态为到达卡位状态；而当倍数小于或等于预设倍数时，模数转化后第二数字信号为低电平，可以确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的倍数来确定卡位状态的话，则当倍数大于预设倍数时，模数转化后的第二数字信号为低电平，可以确定卡位状态为到达卡位状态；而当倍数小于或等于预设倍数时，模数转化后的第二数字信号为高电平，可以确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的差值来确定卡位状态的话，则当差值大于预设差值时，模数转化后的第二数字信号为高电平，可以确定卡位状态为到达卡位状态；而当差值小于或等于预设差值时，模数转化后的第二数字信号为低电平，可以确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的差值来确定卡位状态的话，当差值大于预设差值时，模数转化后的第二数字信号为低电平，可以确定卡位状态为到达卡位状态；而当差值小于或等于预设差值时，模数转化后的第二数字信号为高电平，可以确定卡位状态为未到达卡位状态。
在本实施例中，通过与驱动电机串联第二负载的方式，结合驱动电机在不同工作状态下的驱动输出电流特性获取第二负载在不同状态下的第二电压信号，并将第二电压信号输出至锁具的主控板中，使得中控板根据第二电压信号确定锁具是否达到卡位，电路结构简单，并可以适配不同的类型的锁具，从而大大降低了锁具的开发和生产成本。
值得说明地，上述任一实施例中所提供的锁具状态监测装置可以是为一集成模块，在锁具的设计过程中，可以通过设置相应的安装位置以及电路连接接口，然后将锁具状态监测装置安装至锁具中，使得锁具状态监测装置与控制器、驱动电机以及供电电源相连接。此外，还可以是将上述任一实施例中所提供的锁具状态监测装置与驱动电机作为一集成模块，作为锁具驱动装置，然后通过直接将锁具驱动装置安装至锁具中，既可实现锁芯驱动和锁具状态监测的功能。
此外，本发明实施例还提供一种锁具总成，包括：主控板、驱动电机 20、锁芯以及上述实施例中所提供的任意一种锁具状态监测装置，其中，主控板与驱动电机20连接，而主控板用于控制驱动电机20转动，驱动电机20的输出轴21与锁芯连接，以使锁芯在驱动电机20的作用下在第一位置和第二位置之间运动，当锁芯位于第一位置时，锁具总成的状态为开锁状态，当锁芯位于第二位置时，锁具总成的状态为加锁状态。而利用锁具状态监测装置对锁具总成的状态进行监测的原理和过程请参照上述实施例所提供的锁具状态监测装置的工作原理，在本实施例中不在进行赘述。
图6为本发明实施例四提供的锁具状态监测方法的流程图。如图6所示，本实施例提供的锁具状态监测方法，应用于上述任一实施例所提供的锁具状态监测装置，其中，具体地，本实施例提供的锁具状态监测方法，包括：
步骤401、获取变阻器的第一固定端与动触端之间，或者第一负载的两端之间的第一电压信号。
变阻器11的第一固定端与动触端111，或第一负载12的两端用于与锁具中的主控板进行连接，以向主控板输出第一电压信号。其中，变阻器11的动触端111用于与锁具中的驱动电机20的输出轴21连接，当处于不同的锁具状态时，驱动电机20的输出轴21旋转至不同的角度，以使得变阻器11接入电路部分的电阻也不相同。其中，变阻器11可以为旋转式电位器，旋转式电位器的转动端用于与驱动电机20的输出轴21连接，以使旋转式电位器的转动端随驱动电机20的输出轴21转动，以改变旋转式电位器接入电路部分的阻值，可见，当驱动电机20的输出轴21驱动锁具中的锁芯进行开锁或者加锁时，同时也会带动旋转式电位器的转动端进行转动，以改变旋转式电位器接入电路中的阻值。
其中，对于驱动电机20的输出轴21与旋转式电位器的转动端之间的连接，可以是通过轴套进行直接连接，也可以是通过传动机构进行连接，在本实施例中不作具体限定。继续参照图2，在一种可能的设计中，驱动电机20的输出轴21上可以设置有主动齿轮22，而在旋转式电位器转动端末端设置有与主动齿轮22相啮合的从动齿轮112，当驱动电机20转动时，就会通过齿轮传动带动旋转式电位器的转动端进行转动，以改变旋转式电位器接入电路中的阻值。
在另一种可能的实现方式中，变阻器11还可以为滑动电阻器，滑动电 阻器的滑动端用于与驱动电机20的输出轴21连接，以使滑动电阻器的滑动端随驱动电机20的输出轴21滑动，以改变滑动电阻器接入电路部分的阻值，其中，对于驱动电机20与滑动电阻器的滑动端之间的连接，可以是通过将转动转化为滑动的运动副进行连接，例如，齿轮齿条机构，可以是在驱动电机20的输出轴21上设置主动齿轮，而在滑动电阻器的滑动端上设置齿条，通过齿轮齿条驱动滑动电阻器的滑动端进行滑动，以改变滑动电阻器接入电路中的阻值。
步骤402、根据第一电压信号确定锁具状态。
变阻器11的第一固定端与动触端或第一负载12的两端用于与锁具中的主控板进行连接，以向主控板输出第一电压信号，以使主控板根据第一电压信号确定锁具状态，其中，锁具状态包括：开锁状态以及加锁状态。
下面通过结合一个具体的实施例对主控板根据第一电压信号确定锁具状态的具体原理进行说明：
可以选取第一电阻作为第一负载12，选取旋转式电位器作为变阻器11，并且，假设第一电阻的阻值为2000Ω。
在锁具处于加锁状态下时，旋转式电位器的阻值为1000Ω，变阻器11的第一固定端与第一负载12的第二端承载的第一电压为3.3V，可见，此时，旋转式电位器上的压降为1.1V，而第一电阻上的压降为2.2V。
而当锁具从加锁状态切换至开锁状态的过程中，驱动电机20发生转动，从而带动旋转式电位器的转动端也发生转动，此时，以旋转式电位器的电阻随着转动后变大为例，当锁芯到达最大位置时，驱动电机20停止转动，此时，假设旋转式电位器增大后的阻值为4000Ω，则此时，旋转式电位器上的压降为2.2V，而第一电阻上的压降为1.1V。
可见，通过主控板根据获取到的第一电压信号不同的数值与每个状态下标定的预设数值进行比较，即可确定锁具状态。
此外，由于主控板上的处理器需要将模拟信号转化为数字信号进行处理，因此，可以通过模数转化器来对获取到的第一电压信号进行处理，即将第一电压信号转化为第一数字信号，并将第一数字信号输入至主控板的第一端口。
具体地，在一种可能的设置方式中，当锁芯位于第一位置时，第一电压信号为第一数值，则此时，根据第一数值进行模数转化后的第一数字信 号为高电平，确定锁具状态为开锁状态；当锁芯位于第二位置时，第一电压信号为第二数值，则此时，根据第二数值进行模数转化后的第一数字信号为低电平，确定锁具状态为加锁状态。
而在另一种可能的设置方式中，还可以是当锁芯位于第一位置时，第一电压信号为第一数值，则此时，根据第一数值进行模数转化后的第一数字信号为低电平，确定锁具状态为开锁状态；当锁芯位于第二位置时，第一电压信号为第二数值，则此时，根据第一数值进行模数转化后的第一数字信号为高电平，确定锁具状态为加锁状态。
在本实施例中，通过将变阻器的接入电路部分与第一负载进行串联，然后在变阻器的接入电路部分与第一负载上加载稳定的第一电压，并将变阻器的动触端与锁具中的驱动电机的输出轴进行连接，从而使得当锁具在利用驱动电机进行开关操作时，也会同时带动变阻器接入电路的部分的阻值发生变化，进而使得变阻器的第一固定端与动触端之间或者第一负载的两端之间的第一电压信号发生变化，并将第一电压信号发送至锁具上的主控板，从而使得主控板根据当前第一电压信号对应不同的数值与每个状态下标定的预设数值进行比较，以实现锁具状态的确定，通过这种驱动电机转动与变阻器阻值之间的强耦合联动关系，只增加了简单的器件就可以实现锁具状态准确的监测，并可以适配不同的类型的锁具，从而大大降低了锁具的开发和生产成本。
图7为本发明实施例五提供的锁具状态监测方法的流程图。如图7所示，本实施例提供的锁具状态监测方法，应用于锁具，该锁具还包括有第二负载30。其中，第二负载30的第一端用于与驱动电机20的第一输入端连接，以使驱动输出电流经第二负载30之后对驱动电机20进行驱动。本实施例提供的锁具状态监测方法，包括：
步骤501、获取变阻器的第一固定端与动触端之间，或者第一负载的两端之间的第一电压信号。
步骤502、根据第一电压信号确定锁具状态。
值得说明地，步骤501-502的具体实现方式参照图5所示实施例中的步骤401-402的描述，这里不再赘述。
步骤503、获取第二负载两端的第二电压信号。
当驱动电机20不工作时，其驱动输出电流为0，而当主控板控制驱动电 机20进行转动且处于锁具不同状态切换过程中时，驱动输出电流即为驱动电机20的正常工作电流，而当锁芯转动至卡位时，无论是开锁状态卡位还是加锁状态卡位，此时，驱动电机20所受到的阻力就会加大，则驱动电机20所需的功率也就自然加大，进而使得此时的驱动输出电流迅速提升，从而使得第二负载30两端的压降升高。
步骤504、根据第二电压信号确定锁具是否达到卡位。
利用驱动电机20上述的工作特性，可以将第二负载30的两端用于与主控板连接，以向主控板输出第二电压信号，以使主控板根据第二电压信号确定锁具是否达到卡位。
下面通过结合一个具体的实施例对主控板根据第二电压信号确定锁具是否达到卡位的具体原理进行说明：
可以选取第二电阻作为第二负载30，并假设第二电阻的阻值为10Ω。
继续参照图5所示，在锁具静止处于加锁状态下或者开锁状态下时，驱动电机20不工作时，其驱动输出电流为0，对应地，此时第二负载30两端的压降也为0V。当主控板控制驱动电机20运动进行锁具状态切换时，例如，从开锁状态切换至加锁状态，此时，驱动电机20开始转动，可以假设此时驱动电机20的正常工作电流为20mA，即驱动输出电流为20mA，对应地，此时第二负载30两端的压降也为200mV。而当驱动电机20继续转动，直至锁芯运动到极限位置，即锁具到达了卡位位置时，此时驱动电机20所受到的阻力就会加大，则驱动电机20所需的功率也就自然加大，进而使得此时的驱动输出电流迅速提升，例如，升高至200mA，进而使得第二负载30两端的压降升高至2V，在获取到第二负载30的两端的第二电压信号之后，还可以将获取到的第二电压信号与每个状态下标定的预设电压数值进行比较，即可确定锁具总成的卡位状态，其中，上述卡位状态包括：到达卡位状态以及未到达卡位状态。
由于主控板上的处理器需要将模拟信号转化为数字信号进行处理，因此，可以通过模数转化器来对获取到的第二电压信号进行处理，即根据第二电压信号生成第二数字信号，并将第二数字信号输入至主控板的第二端口。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的倍数来确定卡位状态的话，则当倍数大于预设倍数时，模数转化后的第 二数字信号为高电平，可以确定卡位状态为到达卡位状态；而当倍数小于或等于预设倍数时，模数转化后第二数字信号为低电平，可以确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的倍数来确定卡位状态的话，则当倍数大于预设倍数时，模数转化后的第二数字信号为低电平，可以确定卡位状态为到达卡位状态；而当倍数小于或等于预设倍数时，模数转化后的第二数字信号为高电平，确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的差值来确定卡位状态的话，则当差值大于预设差值时，模数转化后的第二数字信号为高电平，可以确定卡位状态为到达卡位状态；而当差值小于或等于预设差值时，模数转化后的第二数字信号为低电平，可以确定卡位状态为未到达卡位状态。
可选地，若是通过获取第二电压信号对应的电压值与预设电压值之间的差值来确定卡位状态的话，当差值大于预设差值时，模数转化后的第二数字信号为低电平，可以确定卡位状态为到达卡位状态；而当差值小于或等于预设差值时，模数转化后的第二数字信号为高电平，确定卡位状态为未到达卡位状态。
在本实施例中，通过与驱动电机串联第二负载的方式，结合驱动电机在不同工作状态下的驱动输出电流特性获取第二负载在不同状态下的第二电压信号，并将第二电压信号输出至锁具的主控板中，使得中控板根据第二电压信号确定锁具是否达到卡位，电路结构简单，并可以适配不同的类型的锁具，从而大大降低了锁具的开发和生产成本。
