【摘要】 依据日常生活中门禁使用的特点,讨论智能门禁中主机全方位参与电源管理的可编程电源逻辑模型。该模型的基本思想是“电源-主机”一体化,主机既是电源的使用者,又是电源供电的控制者。软件控制系统用电,不但实现了实质性高效节能,而且进一步提高了智能门禁的智能程度。更多还原

【Abstract】 According to the characteristics of entrance guard used in daily life, the programmable power logic model, in which host computer omni- directionally participates in the management of the power, used in intelligent entrance guard is discussed. The basic thought of this model is the " power- host micorocontroller" integrating, the host computer is not only a user of the power, but also a controller of power supply. That software controls the electricity of the system not only has realized the substantive energy- efficient, but also further improves the intelligent degree of the intelligent entrance guard.更多还原
