背景技术Background technique

现有的人脸识别门禁装置是通过整块主控制板来集成全部外设功能,例如:测温、刷卡、门禁开关和语音提示等。并且现有的人脸识别门禁装置的主控制板大都采用Linux主板,这增加了人脸识别门禁装置的整体成本,若当部分外设存在问题时,则将会导致整块Linux主板返厂维修,而降低主板的流通性。且在升级主控制板的过程中,主控制板上的控制器需要重新与主控制板的外设接口进行适配,而这又需要投入较大的人力成本。并且主控制板的外设接口的资源有限,因此,所有处理逻辑都需要使用主控制板的控制器的资源,这样就会导致AI算法在执行推理分析时速度变慢,从而导致人脸识别的效率较低。Existing face recognition access control devices integrate all peripheral functions through the entire main control board, such as temperature measurement, card swiping, access control switches and voice prompts. In addition, the main control boards of the existing face recognition access control devices mostly use Linux motherboards, which increases the overall cost of the face recognition access control devices. If there are problems with some peripherals, the entire Linux motherboard will be returned to the factory for maintenance. , and reduce the liquidity of the motherboard. In addition, in the process of upgrading the main control board, the controller on the main control board needs to be re-adapted with the peripheral interface of the main control board, which requires a large labor cost. In addition, the resources of the peripheral interface of the main control board are limited. Therefore, all processing logic needs to use the resources of the controller of the main control board, which will cause the AI algorithm to slow down when performing inference analysis, resulting in the failure of face recognition. less efficient.
