门禁系统与非公共区域的电动门
Access control system and electric doors in non-public areas
如果说对电动门的性能和质量要求最高的,是在使用频率极高的大型公共区域,那么电动门功能要求最高是对进出人员进行选择的非公共区域。门禁系统是对入门授权的识别。在识别或检测入门授权通过以后,向电动门的控制系统提供开门信号。在提供开门信号之前,电动门必须处于锁门的状态。门禁系统包括从最简单的钥匙开关,密码锁,磁卡锁。(考勤统计系统)。一直到复杂的体重识别系统,指纹识别系统等。但无论系统怎样复杂,最终都是给电动门提供开门的触点信号。信号电路的屏蔽对避免由于无关信号的干扰而误开门的情况发生非常重要。
If the performance and quality requirements of the electric door are the highest in the large public areas with extremely high frequency of use, the function requirements of the electric door are the highest in the non-public areas where the access personnel are selected. Access control system is the identification of entry authorization. After the identification or detection of the entry authorization is passed, the door opening signal shall be provided to the control system of the electric door. Before the door opening signal is provided, the electric door must be in the locked state. The access control system includes the simplest key switch, password lock and magnetic card lock. (attendance statistics system). Until the complex weight recognition system, fingerprint recognition system and so on. However, no matter how complex the system is, it will eventually provide the contact signal for the electric door to open the door. The shielding of signal circuit is very important to avoid false door opening due to the interference of irrelevant signals.
