As a new type of modern safety management system, attendance access control management system integrates computer automatic identification technology and modern safety management measures, involving many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. It is an effective measure to solve the security management at the entrance and exit of important departments.
Attendance and access control management system, also known as access management control system, is a digital management system for managing personnel access. Common attendance access control management systems include: password attendance access management system, non-contact IC card (inductive IC card) attendance access management system, fingerprint iris palm biometric attendance access management system, etc.
2. Principle of attendance access control management system
1. For the entrances and exits that need to be controlled, install electric control doors controlled by electric lock devices and sensors (such as electronic password keyboards, card readers, fingerprint readers, etc.);
2. Authorized personnel can open the electric control door with a valid card, or password and their own fingerprints;
3. All access data are recorded by the background computer; the access authority of authorized personnel can be modified at any time through the background computer;
4. The system can also add attendance system functions (including network attendance).
3. The composition of attendance access control management system
The attendance access control management system is composed of access control controller, access control card reader, card, electric lock and corresponding software, power supply and other related access control equipment.
Access control controller: The core part of the attendance access control management system, which is equivalent to the CPU of the computer. The quality and performance of the access control controller directly affects the stability and function of the attendance access control management system. It is responsible for the processing, storage, and control of the input and output information of the entire system. It verifies the reliability of the input information of the access control card reader, and judges its validity according to the access rules.
Access control card reader: It is the key device for the signal input of the attendance access control management system, which is used to read the data in the card or its related biometric information
Card: It is equivalent to the role of the key, and it is also the proof of entry and exit. In terms of working methods, it can be divided into contact cards (including magnetic cards and contact IC cards or all-in-one cards) and inductive contactless cards. Among them, contactless ID cards and contactless IC cards are widely used due to their long service life and strong confidentiality. .
Electric lock: The executive component of door lock in the attendance access control management system. There are mainly the following types:
(1) Electromagnetic lock: It is a power-off door lock, which meets the fire protection requirements. This lock is suitable for one-way wooden doors, glass doors, fire doors, and two-way electric doors.
(2) Anode lock: Anode lock is a power-off door type, which meets fire protection requirements. It is installed on the upper part of the door frame. It is suitable for two-way wooden doors, glass doors, fire doors, and it has a door magnetic detector, which can detect whether the door is closed at any time.
(3) Cathode lock: The general cathode lock is a power-on type to open the door. Suitable for one-way wooden doors. The installation of the cathode lock must be equipped with a UPS power supply. Because the female lock locks the door when the power goes out.
Access control software: Realize the functions of monitoring, management and query of attendance access control management system. Managers can expand and complete functions such as patrolling, attendance, and personnel positioning through adjustment.
Power supply and other related access control equipment: The power supply is the energy responsible for the entire attendance access control management system. Other access control devices, such as the exit button, press the open door device, which is suitable for the situation where there is no restriction on going out; another example is the door sensor, which is used to detect the safety/switch status of the door.
