The access control system is generally used in residential areas, office buildings, factories, office rooms and other scenarios. The release of the personnel of the unit is realized by the signal input of the access control controller to the electronic lock to open and close the door. The common access control systems include credit card access control and face recognition access control. Electronic locks also play an important role in access control systems.
In conventional access control systems, commonly used electronic locks are divided into electromagnetic force locks and electric bolt locks.
Magnetic lock (Electromagnetic Lock) uses the principle of electricity to generate magnetism. When the current passes through the original relay, a strong suction force is generated and the magnetic lock patch is adsorbed to achieve the effect of locking the door. When the access control system recognizes the signal to allow passage, the power supply of the magnetic lock is cut off, and the magnetic tool and the patch are separated to realize the release. However, because of the operation principle of the magnetic lock and the factors of the installation structure, the door body with the magnetic lock can only be opened in one direction. Magnetic locks are highly adaptable for installing door bodies and can be applied to most glass doors, fire doors, wooden doors, wrought iron metal doors, etc. When the use environment is powered off, the magnetic lock will also lose its suction power, so in some scenarios, it will be used with UPS power supply or battery.
The electric bolt lock is composed of two parts: the lock body and the lock plate. When the access signal of the access control controller is input, the motor drives the lock body to disengage from the lock plate to realize the release. Electric bolt locks are generally installed in the beam of the door frame and on the door leaf, so the door body with the electric bolt lock can be opened in two directions, which is often used in the scene of two-way glass doors.
