  9. 一种采集人脸识别控制系统的控制方法,其特征在于以下步骤:
    步骤1、采用红外传感器对门禁范围内人员进行检测,而红外传感器受到非恒定强度的红外光照射时,产生的温度变化导致其表面电极的电荷密度发生改变,从而产生热释电电流,当人体的温度参数在红外传感器的响应范围内,就会将采集单向信号经过控制器转换为单向输出电压;
    步骤2、进一步对红外传感器的输入电源进行储存,结合三极管导通、饱和、截止三种状态,对储存电压进行输入、输出控制,进一步给门禁采集系统提供稳定的储存电源,从而保障门禁采集系统在断电以及亏电状态下的正常运行;
    步骤3、采用串联传输的方式,控制红外感应模块的输出电压,对输出电压采用递进传输,进而降低电压的分布,增强模块平稳的运行;
    步骤4、接收红外感应模块的转换输出电压,采用阻断输出电压传输的方式,延长电压的传输,实现延时触发效果,从而降低长时间的电压损耗,进而完成延时控制电压的输出;
    步骤5、将延时后的电压传输给光感控制电路,利用自然光的亮度调节门禁人脸识别系统补光亮度,进而实现自然光的明暗,控制补光的亮度,进而降低了电能的损耗以及在黑暗状态对人眼造成的视觉影响;
    步骤6、采用三极管作无触点开关,控制电压的传输,进而根据自然光的亮度变化改变内部阻止,进而降低电压的输出数值,进一步实现亮度的变化调节;
    步骤7、采用电压分向处理,从而提供不同支路电压,直接给人脸识别系统提供运行电压,使门禁内部摄像头对门禁人员进行拍照,从而将拍照的图像与云存储图像进行对比,进而完成门禁人员的检测,保护住户的安全。
