技术领域
本发明涉及通信技术领域，尤其涉及一种控制方法、装置及电子设备。
背景技术
随着电子技术的不断发展，以手机和平板电脑为主的电子设备已经成为人们生活和工作的必须品，为满足人们对屏幕的使用需求，全面屏手机逐渐成为市场的主流，为保证全面屏的显示效果，可升降摄像头模组应运而生。
可升降摄像头模组主要由电子设备中的步进马达为可升降摄像头模组提供驱动力，步进马达可以控制可升降摄像头模组和磁铁的上升和下降。在可升降摄像头模组的升降过程中，电子设备中的霍尔开关检测的磁通量会随着磁铁的运动产生变化，所以可以通过霍尔开关检测到的磁通量，判断可升降摄像头模组是否伸缩到位。
但是，可升降摄像头模组的上升距离是有限的，而预留给可升降摄像头模组的上升时间可能会较长，如可升降摄像头模组0.6秒就可以升到顶，但预留的上升时间可能会设置为0.8秒。如果可升降摄像头模组已经升到顶，而步进马达仍以高转速为可升降摄像头模组提供驱动力，就会引起高转速的堵转，导致线圈发热，引起磁场混乱以及磁极反转，此时，就会引发可升降摄像头模组自行收缩的问题。所以，现有技术方案中缺少一种有效的驱动装置控制机制。

具体实施方式
本发明实施例提供一种控制方法、装置及电子设备。
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
实施例一
如图1所示，本发明实施例提供一种控制方法，该方法的执行主体可以为配置有包括可升降摄像头模组，检测组件及驱动装置的电子设备，其中，该电子设备可以如手机、平板电脑等移动电子设备，检测组件包括至少一个磁场传感器及磁体，磁体与可升降摄像头模组固定连接。该方法具体可以包括以下步骤：
在S102中，在驱动装置驱动可升降摄像头模组上升的过程中，通过至少一个磁场传感器获取磁场变化信息。
其中，磁场变化信息可以包括磁通量信息或磁通量变化信息等。
在实施中，随着电子技术的不断发展，以手机和平板电脑为主的电子设备已经成为人们生活和工作的必须品，为满足人们对屏幕的使用需求，全面屏手机逐渐成为市场的主流，为保证全面屏的显示效果，可升降摄像头模组应运而生。
如图2所示，电子设备可以包括壳体、可升降摄像头模组、驱动装置以及检测组件，其中，壳体设置有开口，驱动装置可以与可升降摄像头模组相连接，并驱动可升降摄像头模组通过电子设备的开口伸出壳体之外，或者驱动可升降摄像头模组通过电子设备的开头回缩到壳体内。
驱动装置可以为可升降摄像头模组提供驱动力，可升降摄像头模组在驱动装置的驱动下，可以在固定轨道内上升或下降，其中，驱动装置可以包括驱动电机以及其他 驱动组件，驱动电机可以为步进马达。在可升降摄像头模组的升降过程中，由于磁体与可升降摄像头模组固定连接，所以磁体与电子设备中的磁场传感器(如可以为电子设备中配置的霍尔开关)之间的距离，也随着可升降摄像头模组的升降发生变化，即磁场传感器检测到的磁场信息会随着磁体的运动产生变化，所以，可以通过磁场传感器检测到的磁场变化信息，判断可升降摄像头模组是否伸缩到位。
但是，可升降摄像头模组的上升距离是有限的，而预留给可升降摄像头模组的上升时间可能会较长，如可升降摄像头模组0.6秒就可以升到顶，但预留的上升时间可能会设置为0.8秒。如果可升降摄像头模组已经升到顶，而步进马达仍以高转速为可升降摄像头模组提供驱动力，就会引起由于高转速的堵转，导致线圈发热，引起磁场混乱以及磁极反转，此时，就会引发可升降摄像头模组自行收缩的问题。所以，现有技术方案中缺少一种有效的驱动装置控制机制。为此，本发明实施例提供一种能够解决上述问题的技术方案，具体可以包括以下内容：
例如，可以基于预设时间节点，在驱动装置驱动可升降摄像头上升的过程中，通过至少一个磁场传感器获取磁场变化信息。驱动装置在为可升降摄像头模组提供驱动力时，可以分为2个不同的驱动阶段，这2个驱动阶段可以为启动阶段和上升阶段。其中，在启动阶段，驱动装置可以通过较小的转速，得到较大的驱动力(驱动力和转速成反比)，以驱动可升降摄像头模组启动。在驱动可升降摄像头模组启动后，为驱动可升降摄像头模组快速到达顶端，可以在上升阶段，通过较高的转速，驱动可升降摄像头模组快速上升。
假设预留给可升降摄像头模组的上升时间(包括启动阶段和上升阶段)为0.8秒，驱动装置驱动可升降摄像头模组启动的时间可以为0.2～0.3秒(即启动阶段所需时间)，驱动可升降摄像头模组上升到顶端的时间可以是0.4～0.6秒(即上升阶段所需时间)。所以，可以分别在第0.2秒、第0.3秒、第0.4秒、第0.5秒和第0.6秒时，通过至少一个磁场传感器检测到的磁场变化信息，判断可升降摄像头模组在启动阶段和/或上升阶段是否发生异常，如可以通过第0.3秒的磁场变化信息，判断可升降摄像头模组是否已启动。
或者，还可以基于预设时间周期，通过至少一个磁场传感器获取磁场变化信息。此外，还可以有多种磁场变化信息的获取方法，可以根据实际应用场景的不同而有所不同，本发明实施例对此不做具体限定。
在S104中，基于磁场变化信息，调整驱动装置的转速。
在实施中，可以根据磁场传感器在电子设备中与磁体的可移动范围之间的相对位 置，确定磁场传感器检测到的磁场信息与可升降摄像头模组的上升距离之间的关系，然后根据在预定时间内磁场信息的变化(即磁场变化信息)，调整驱动装置的转速。例如，如图3所示，假设电子设备包括一个磁场传感器，且位于电子设备壳体开口处，即位于磁体的可移动范围的上方，那么，在磁体随着可升降摄像头模组上升的过程中，磁场传感器可以检测到的磁场信息(如磁通量)逐渐变大，即磁场传感器检测到的磁通量与可升降摄像头模组的上升距离之间的关系为正比。
在确定了磁通量与可升降摄像头模组的上升距离之间的关系后，可以基于检测到的磁通量，或检测到的磁通量的变化，对驱动装置的转速进行调整。
例如，如图3所示，磁场传感器检测到的磁通量与可升降摄像头模组的上升距离之间的关系为正比，如果检测到磁通量大于预设阈值，则可以将驱动装置的转速调整为预设转速。例如，在可升降摄像头模组处于未启动状态时，磁场传感器检测到的磁通量为Q1，在可升降摄像头模组启动后的第0.6秒，磁场传感器检测到的磁通量为Q2，如果预设的第0.6秒对应的磁通量的预设阈值为Q3，则可以对Q2是否大于Q3进行检测。如果Q2大于Q3，则表明此时可升降摄像头模组已经升到顶端，此时可以将驱动装置的转速调小到预设转速，以避免驱动装置发生高转速堵转的问题。
上述基于磁通量对转速进行调整的方法，是一种可选地、可实现的调整方法，在实际应用场景中，磁场传感器与可升降摄像头模组(即磁体的可移动范围)之间的位置关系可以有多种，不同的位置关系，可以对应有不同的转速调整方法，本发明实施例对此不作具体限定。
本发明实施例提供的一种控制方法，应用于电子设备，电子设备包括可升降摄像头模组、检测组件及驱动装置，检测组件包括至少一个磁场传感器及磁体，磁体与可升降摄像头模组固定连接，方法包括：在驱动装置驱动所述可升降摄像头模组上升的过程中，通过至少一个磁场传感器获取磁场变化信息，基于磁场变化信息，调整驱动装置的转速。这样，就可以根据检测到的磁场变化信息，对驱动装置的转速进行调整，避免了由于无法有效的对驱动装置的转速进行控制，而引起的可升降摄像头模组自行收缩的问题。
实施例二
如图4所示，本发明实施例提供一种控制方法，该方法的执行主体可以为配置有包括可升降摄像头模组，检测组件及驱动装置的电子设备，其中，该电子设备可以如手机、平板电脑等移动电子设备，检测组件包括至少一个磁场传感器及磁体，磁体与可升降摄像头模组固定连接。该方法具体可以包括以下步骤：
在S402中，在驱动装置驱动可升降摄像头模组上升的过程中，通过至少一个磁场传感器获取磁场变化信息。
上述S402的具体处理过程可以参见上述实施例一中S102的相关内容，在此不再赘述。
在S404中，基于第一磁通量和第二磁通量中的至少一个，调整驱动装置的转速。
其中，检测组件可以包括第一磁场传感器和第二磁场传感器中的至少一个，第一磁场传感器检测到的第一磁通量可以为随着磁体的上升而逐渐变小的磁通量，第二磁场传感器检测到的第二磁通量可以为随着磁体的上升而逐渐变大的磁通量。
在实施中，如图5所示，第二磁体传感器可以位于第一磁体传感器的上方，且第一磁体传感器可以位于磁体的可移动范围的下方，第二磁体传感器可以位于磁体的可移动范围的上方，即第二磁体传感器与电子设备壳体的开口之间的距离，小于第一磁体传感器与电子设备壳体的开口之间的距离。所以，在磁体随着可升降摄像头模组的上升过程中，磁体与第一磁体传感器之间的距离逐渐变大，磁体与第二磁体传感器之间的距离逐渐变小，即第一磁体传感器检测到的磁通量逐渐变小，第二磁体传感器检测到的磁通量逐渐变大。
所以，可以根据第一磁通量和第二磁通量中的至少一个，对驱动装置的转速进行调整。
此外，还可以基于第一磁通量和第二磁通量的磁通量差值，调整驱动装置的转速。例如，可升降摄像头模组的上升过程可以分为3个阶段，分别为启动阶段P1、上升阶段P2以及降速阶段P3。如图6所示，在检测到可升降摄像头模组与起始位置之间的距离为H1时，可以将对应的转速调整为预设的P2阶段的转速。其中，可升降摄像头模组与起始位置之间的距离，可以根据第一磁通量和第二磁通量之间的磁通量差值确定，差值越大，可升降摄像头模组与起始位置之间的距离越大。本发明实施例对基于磁通量差值确定可升降摄像头模组与起始位置之间的距离的方法不做具体限定。
在检测到磁通量差值小于预设磁通量阈值的情况下，可以将驱动装置的转速调小为预设转速，以使驱动装置在可升降摄像头模组将要上升到顶时，基于预设转速给可升降摄像头模组提供驱动力。例如，如图6所示，当检测到可升降摄像头模组的上升距离达到H2时(即检测到磁通量差值小于预设磁通量阈值时)，可以将驱动装置的转速调小为预设转速，以避免在可升降摄像头模组升到顶端时，驱动装置仍以高转速为可升降摄像头模组提供驱动力，而发生磁极反转的问题。
或者，还可以基于磁通量差值在预定时间长度内的变化量，调整驱动装置的转速。
为保证可升降摄像头模组上升的效果，可以基于预定时间长度的变化量，即时对驱动装置的转速进行调整，即，如图7所示，可以将可升降摄像头模组的上升过程划分为多个阶段，每个阶段的时长即为上述预定时间长度，可以基于不同时间段内，磁通量差值的变化量与转速的预设对应关系，基于磁通量差值在预定时间长度内的变化量，确定对应的驱动装置的转速，并对驱动装置的转速进行调整，以较小的转速变化量，使可升降摄像头模组能够较为平滑的从电子设备壳体的开口处升出，或较为平滑的从电子设备的开口回缩至壳体内，有较好的用户观感。
此外，上述S404是一种可选地、可实现的转速调整方法，除此之外，还可以通过S406～S408对驱动装置的转速进行调整，即在S402后，可以继续执行S406～S408。
在S406中，在磁场变化信息满足第一条件时，调整驱动装置的转速至第一转速。
其中，在磁场变化信息中的磁通量与可升降摄像头模组的上升距离之间为正比关系的情况下，第一条件可以包括：磁通量大于第一预设阈值或磁通量变化值大于第一预设变化阈值等条件。
在实施中，例如，如图3所示，磁场传感器检测到的磁通量(即获取的磁场变化信息可以包括磁通量信息)与可升降摄像头模组的上升距离之间的关系可以为正比关系，在磁通量大于第一预设阈值(即磁场变化信息满足第一条件)时，可以认为可升降摄像头模组处于上升阶段，可以将驱动装置的转速调整至第一转速，以使可升降摄像头模组快速从电子设备壳体的开口伸出。
此外，在磁场变化信息中的磁通量与可升降摄像头模组的上升距离之间为反比关系的情况下，第一条件可以包括：磁通量小于第一预设阈值或磁通量变化值小于第一预设变化阈值等条件。
在S408中，在磁场变化信息满足第二条件时，将驱动驱动装置的转速由第一转速调整至第二转速。
其中，第二转速可以小于第一转速，在磁场变化信息中的磁通量与可升降摄像头模组的上升距离之间为正比关系的情况下，第二条件可以包括：磁通量大于第二预设阈值或磁通量变化值大于第二预设变化阈值等条件，第二预设阈值可以大于第一预设阈值，第二预设变化阈值可以大于第一预设变化阈值。
在实施中，例如，如图3所示，磁场传感器检测到的磁通量(即获取的磁场变化信息可以包括磁通量信息)与可升降摄像头模组的上升距离之间的关系可以为正比关系，假设可升降摄像头模组的上升过程可以分为3个阶段，分别为启动阶段P1、上升阶段P2以及降速阶段P3。
当磁场变化信息满足第一条件(如磁通量大于第一预设阈值)时，可以认为可升降摄像头模组此时处于上升阶段，可以将驱动装置的转速调整至第一转速，以使可升降摄像头模组从电子设备壳体的开口快速伸出。当磁场变化信息满足第二条件(如磁通量大于第二预设阈值)时，可以认为可升降摄像头模组处于降速阶段，可以将驱动装置的转速由第一转速调整至第二转速，以避免发生高速堵转的现象。
本发明实施例提供的一种控制方法，应用于电子设备，电子设备包括可升降摄像头模组、检测组件及驱动装置，检测组件包括至少一个磁场传感器及磁体，磁体与可升降摄像头模组固定连接，方法包括：在驱动装置驱动所述可升降摄像头模组上升的过程中，通过至少一个磁场传感器获取磁场变化信息，基于磁场变化信息，调整驱动装置的转速。这样，就可以根据检测到的磁场变化信息，对驱动装置的转速进行调整，避免了由于无法有效的对驱动装置的转速进行控制，而引起的可升降摄像头模组自行收缩的问题。
