Software Design Of Access Control System For Library

Access control system,an important branch of security system,is an effective method to solve the security problem of entrance management of important places.The traditional method of access control using lock or access card is not safe enough to satisfy the high safety requirement in some places.Therefore,developing an access control system software applied in archives,museums and other important places,has great potential in engineering field.In order to meet the needs of centralized,intelligent control of access management in archives,museums,library and other places,this thesis has developed a software of access control system.The software is the core component of the access control system,which could achieve personnel access control,real-time alarm trigger and processing,process records and backtracking functions.Aiming at personnel control,a multi-channel access control scheme based on face recognition is designed.The scheme is used to control personnel's access flow,and is implemented to realize the safe and effective management of concurrent authentication events.Meanwhile,the real-time alarm analysis and processing scheme in the control module is used to monitor the state of the system.And once an unexpected event happens,it will trigger alarm and notify the user of the alarm processing.In order to facilitate the process backtracking,the system software will store the data related to authentication event and alarm event.In addition,in order to realize the efficient storage of multi-channel audio and video data,an audio and video data storage scheme is developed.The access control system software developed in this thesis has been put into practical application,implementing the personnel access security control in application site,as well as meeting the requirement of function and performance.
