Description

BACKGROUND OF THE INVENTION This application claims priority for the TW application No. 113142811 filed on 7 Nov. 2024, the content of which is incorporated by reference in its entirely. FIELD OF THE INVENTION The invention relates to a control system and method thereof, in particular, to an access control system and method thereof. DESCRIPTION OF THE PRIOR ART For the purposes of safety, epidemic prevention and hierarchical management, it is quite common to set up controlled areas in enterprises, hospitals, public institutions and other places. Generally speaking, access control in controlled areas is performed by issuing a proximity card to the user, and allowing the user to control the opening and closing of the gate or door by placing the proximity card close to the reader for authentication when entering or exiting. However, special drugs in current hospitals are often managed and distributed manually, which leads to problems in management. Therefore, relying solely on the proximity card for authentication cannot be effective in management. In order to help hospitals effectively establish intelligent drug management, the first thing to do is to strengthen the access control system to control the authority of drug recipients and provide a multiple verification mechanism so that the entire delivery process can be effectively checked and recorded. In this way, the safety and accuracy in management of collection and delivery for special drugs can be improved, and the collection and delivery time can be shortened, thereby improving control efficiency and quality in drug management. SUMMARY OF THE INVENTION The invention provides an access control system and method thereof, which may provide dual authentication of proximity cards and shift schedules, thereby improving control efficiency and quality in management. The invention provides an access control system including an electronic lock, a storage unit, a proximity card reader and a control unit. The storage unit stores a shift schedule including a plurality of scheduled personnel data, each of the scheduled personnel data including a scheduled personnel field and a time slot field. The proximity card reader reads any one of a plurality of proximity cards to obtain a personnel information, each of the personnel information corresponding to one of plurality of scheduled personnel data. The control unit is connected to the electronic lock, the storage unit and the proximity card reader. When the proximity card reader reads one of the proximity cards, the control unit obtains one of the scheduled personnel data from the storage unit according to the personnel information, and the control unit determines whether the current time matches the time slot field corresponding to the one of the scheduled personnel data. When the control unit determines that the current time matches the time slot field corresponding to the one of the scheduled personnel data, the control unit unlocks the electronic lock. In an embodiment of the invention, the access control system further includes a mobile network module, which is connected to the control unit. When the control unit determines that the current time matches the time slot field corresponding to the one of the scheduled personnel data, the control unit receives an authentication information from the mobile network module so that the control unit unlocks the electronic lock according to the authentication information. In an embodiment of the invention, the access control system further includes a sound receiving unit and an artificial intelligence voice recognition module. The sound receiving unit is connected to the control unit, the control unit receiving a voice signal via the sound receiving unit. The artificial intelligence voice recognition module is connected to the control unit via the mobile network module. The control unit transmits the voice signal to the artificial intelligence voice recognition module, and the artificial intelligence voice recognition module recognizes the voice signal as the authentication information. In an embodiment of the invention, each of the scheduled personnel data further includes a password field. When the control unit receives the authentication information from the mobile network module, the control unit determines whether the authentication information matches the password field corresponding to the one of the scheduled personnel data. When the control unit determines that the authentication information matches the password field corresponding to the one of the scheduled personnel data, the control unit unlocks the electronic lock. In an embodiment of the invention, the artificial intelligence voice recognition module includes a voiceprint feature extraction unit and a voiceprint feature matching unit. The voiceprint feature extraction unit extracts at least one voiceprint feature of the voice signal. The voiceprint feature matching unit matches the at least one voiceprint featu
