Design And Implementation Of Laboratory Access Guard System

With the change of the social demand for talents,experiment education has been paid more and more attentions.For this reason,the university laboratory undertakes a lot of important teaching tasks.And so far,experimenters are not only taking on the management of the lab,but also doing some experimental teachings.The use of the entrance guard system can relieve the pressure of the experimenters and improve the working efficiency,as well as a part of the intelligent management of the laboratory.In the past,the experimenter managed the lab's door using keys,which caused a lot of inconvenience and insecurity.The system solves these problems and makes it convenient for teachers and students to use the laboratory.This system not only solves these problems but also facilitates the use of laboratory by teachers and students.The design mentioned in this thesis is based on the laboratories of Nanjing Audit University.The primary work is as follows.Firstly,the paper describes the research background,current situation and development trend of the entrance guard system.Make implement plan according to actual requirement of experiment center.Secondly,develop the hardware architecture and choose the right chip for access control controller and other equipment.Thirdly,design database used to interface the original system,where the software system is introduced in detail.Finally,sums up the existing shortages and improvement directions.
