具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面,但是除非特别指出,不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中术语“至少一种”表示多种中的任意一种或多种中的至少两种的任意组合,例如,包括A、B、C中的至少一种,可以表示包括从A、B和C构成的集合中选择的任意一个或多个元素。

相关技术中,人脸识别模组与视频监控模组在结构上相互独立。如果需要智能门锁同时具备人脸识别功能和视频监控功能,则需要同时采用人脸识别模组和视频监控模组这两个模组,导致成本较高。另外,由于同时采用人脸识别模组和视频监控模组,导致智能门锁中的PCBA(Printed Circuit Board Assembly,印刷电路板装配)的数量较多,至少包括人脸识别模组的PCBA和视频监控模组的PCBA这两块PCBA。智能门锁中的PCBA的数量较多,将导致在智能门锁的结构设计与装配时的难度较大。再者,由于需要两个模组来单独实现人脸识别功能和视频监控功能,导致门锁主控板需要有更多的数据接口和/或控制接口来与这两个模组进行连接。
为了解决类似上述所述的技术问题,在本公开实施例中,人脸识别和视频监控共用同一个电路板组件上的主芯片进行处理,由此,能够解决智能门锁中PCBA数量过多的问题,从而能够节省智能门锁内部的空间,降低硬件成本,降低智能门锁的装配难度,且尺寸较小,能够方便智能门锁的结构设计。由于本公开实施例提供的电路板组件能够降低智能门锁的装配难度,因此能够缩短新的智能门锁产品的研发周期,并有效降低研发 成本。另外,通过减少PCBA的数量,能够减少不同PCBA之间复杂的布线,从而降低智能门锁生产时的装配成本。再者,通过同一个电路板组件上的主芯片实现人脸识别功能和视频监控功能,还能够节省门锁主控板所需的数据接口和/或控制接口的数量。
