User permission control method and system based on fingerprint identification

The invention relates to a user permission control method and a system based on fingerprint identification. The core of the invention is that a simplified fingerprint machine is used to acquire fingerprint information; user fingerprints and corresponding user information are set through an information management center of the upper computer; the method comprises the following steps: binding user fingerprint information with user information; according to the method, the user authority parameters are determined, the accuracy of the user information and the use safety of the user authority are further ensured through authority setting and verification of the PLC end, and meanwhile, the user information and authority information update are set in real time in the upper computer, so that humanization and information management flexibility are realized. 本发明涉及一种基于指纹识别的用户权限控制方法及系统，本发明的核心是采用简化的指纹机进行指纹信息获取，并通过上位机的信息管理中心进行用户指纹及其相应的用户信息设置，包括对用户指纹信息与用户信息的绑定，用户权限参数的确定，进而还通过PLC端的权限设置与校验，进一步确保用户信息的准确性及用户权限使用的安全性，同时通过在上位机中实时
