The invention provides an access management system based on access control and a management method thereof. The management system comprises a server, a client, an access control card issuing machine,access control equipment and data collecting equipment, wherein the server is connected with the client by a network and is provided with access authority management software and a database which corresponds to the access authority management software and is used for storing access authority information; the client is connected with the access control card issuing machine, the access control equipment and the data collecting equipment; the access control card issuing machine issues access control cards according to the authority information of the database of the server and inputs the information of persons corresponding to the authority information into the access control cards; when the access control cards are used, the information of the persons is input into the access control equipment; and the data collecting equipment is used for reading the information of the persons in the access control equipment and sending the information to the server. The access management system effectively combines access control management with access management, improves the controllability of security management and realizes the omnidirectional tracing of accessing persons.
