In modern buildings, magnetic locks and access control systems are common security devices that work together to provide access control and security, and they lock and unlock door locks through electromagnetic principles. The magnetic lock works in conjunction with the access control system to effectively manage the entry and exit of people in a specific area. Below we will detail how the magnetic lock works in conjunction with the access control.
First, the principle of magnetic lock.
A magnetic lock is a lock that uses the magnetic force of an electromagnet to control the expansion and contraction of the deadbolt. When an electric current is passed through the electromagnet, the electromagnet creates a magnetic force that draws the deadbolt to the locked position, locking the door. Magnetic locks are usually installed on the door frame or door panel, and the magnitude of their magnetic force is proportional to the current, so the locking and unlocking of the magnetic lock can be controlled by adjusting the current.
Second, the principle of access control system.
The access control system is a system that identifies and manages the entry and exit of personnel, which authenticates the entry and exit personnel through technical means such as card swiping, password, and biometrics, and controls the opening and closing of the door. The access control system is usually composed of a controller, a card reader, an access control power supply, a magnetic lock, etc.
Third, the principle of the operation of the magnetic lock and the access control system.
1.Card reader reading card information: When a person needs to enter or leave a specific area, they need to swipe the card close to the card reader. The card reader reads the information on the card, such as the card number, expiration date, etc.
2.Access controller judgment authority: The card reader transmits the read card information to the access controller. The access controller will determine whether the card has permission to enter or leave a specific area based on the preset permission rules. If you have permissions, the access controller sends an unlock signal to the magnetic lock;If there is no permission, the access controller will not send any signal.
3.Magnetic lock unlocking: When the access controller sends an unlocking signal to the magnetic lock, the electromagnet is energized, generating a magnetic field, attracting the deadbolt, making the deadbolt detach from the lock body, and realize the opening of the door lock. At this point, people can enter or leave a specific area.
4.Magnetic lock locking: When the person completes the entry and exit operation, the access controller will send a lock signal to the magnetic lock. The electromagnet is powered off, the magnetic field disappears, and the deadbolt is reset under the action of the spring, and the lock body is inserted to realize the locking of the door lock. At this point, the specific area is closed again, and no other personnel can enter.
5.Record access information: During the whole process, the access controller will also record the entry and exit information of personnel, such as entry and exit time, entry and exit times, etc. This information can be used for later statistics and analysis, so that managers can understand the usage of a particular area.
