深圳创先智能中央门禁控制LAC系统概述

YYD
YYD over 14 years ago

来源:慧聪安防网

LAC是一套可根据系统的大小选择规模、功能强大、精准、实时、支持多客户端的分布式且符合微软视窗易使用的特点,整个系统可实现复杂功能而不失简单易用极大提高管理人员的工作效率,为客户实现增值价值。LAC分为中央控制部分,

前端控制部分及前端读三部分,各部分有机协调处理,完成其强大的门禁功能。

    中央门禁控制器LAC

    LAC中央门禁控制器是采用IntelCPU的控制器,防静电、防尘、双重看门狗保护

    具有强大的处理功能,具备可靠、持久、稳定等高规格安防产品特性;

    LAC提供标准工控RS485现场控制器通讯通道(DLN),通讯通道可最大连结8个现场控制单元(DCU)自由组组合成单门、双门、四门、八门系列控制器;

    LAC提供标准工控RS485前端读卡器通讯通道(RLN),通讯通道可最大连结8个前端读卡器,即时采集刷卡数据上传中央门禁控制器;

    LAC采用TCPIP方式与主机通讯能及时把数据上传到系统中心,控制器每秒可传送100条记录、数据传输采用SSL加密格式确保安全;

    LAC能够独立处理所有的事件,应用程序独立存在于本机RAM中而无需依赖系统主机工作,即使与系统主机失去通讯也能正常工作,保证系统的完整性、可靠性;

    卡用户达10,000个,脱机储存40,000条刷卡记录及1,000条系统日志、管理日志;

    每道门有8个开放时间段,可以组合出无限制的权限分类;

    支持防潜返,单门防潜返、多门防潜返,用于分区管理;

    支持有效日期,包括起止日期,精确至开放时间,过期卡会自动失效;

    支持信用量功能,可授权在规定的日期内的开门次数,用于实现计次消费;

    多种鉴别方式有单卡、密码、卡加密码等;

    LAC具备防撬功能当设备遭破坏时可即时驱动报警输出;

    现场门控单元DCU

    DCU现场门控模块应用在中央门禁处理器LAC及前端门锁之间,主要执行中央控制器发出的指令开启或关闭电锁;DCU现场门控模块适应安装在任何位置,可隐蔽分装在天花板上或集中安装在中央门禁控制箱内;

    门禁前端485读卡器

    标准485读卡器

    通过数据通道DLN把刷卡数据上传到中央门禁控制器

    性能稳定,先进的防死机电路设计,防浪湧保护;
