摘要
目的探讨指纹门禁系统中人员权限的分配方法以及有权限人员在进入特定区域时被跟随或被胁迫的解决办法。方法用数据库实现人员权限分配;用两道防盗门组成一个封闭空间实现防尾随功能,设置两道门的联动程序,使第一道门的开关状态成为第二道门开关的前提条件。结果人进入特定区域时,要先进行指纹扫描,将扫描指纹与数据库中保存的人员指纹信息进行比较,可以成功地将没有权限的人员拒之门外;当有权限人员被尾随或被胁迫时,防尾随功能模块会发出报警信号,管理人员采取相应措施,即可避免意外发生。结论通过对人员权限的设置来界定人员可以出入的范围,在很大程度上减轻了管理人员的负担;防尾随和防胁迫模块的设计,有效阻止了一些犯罪事实的发生,减少经济损失的同时也保障了工作人员的人身安全。
Objective To discuss allocation method of personnel access in the fingerprint entrance guard system and solution to the problem of the authority personnel’s being tailed or or coerced in the specific area.Methods Using database to implement personnel rights allocation;using two security doors to form a closed space to implement the anti-tail function:setting up the linkage of the two doors,making switch state of the first door become precondition of opening and closing of the second door.Results When people came into a particular area,their fingerprints were scanned;the scanned fingerprint was compared with the fingerprint information saved in the database,thus successfully shutting out of those without permissions;when authorized personnel was followed or coerced,the anti-tail function module sent signals to alarm management personnel to take corresponding measures,thus avoiding accidental damage.Conclusion Permission setting is to used define personnel’s access scope,which,to a great extent,alleviates the burden of the management;design of anti-tail and anti-coerce module effectively prevents some criminals,reduces economic loss and ensures the staff’s personal safety at the same time.
