Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of access control system, specifically an access control device. BACKGROUND

[0002] In order to strengthen security and relieve the pressure of artificial identity verification, access control systems are generally used in offices in office buildings, high-rise buildings or other occasions, and the magnetic lock access control system is a commonly used access control system, which uses a magnet to attract an iron block to achieve the purpose of locking the door. When the magnetic lock is powered off, the magnetic force disappears, the attraction of the adsorbed iron plate loses the magnetic force, and the door can be easily pushed open. However, after long-term frequent use of the magnetic lock, the iron core and the adsorbed iron plate may exhibit a certain degree of magnetic hysteresis phenomenon due to repeated magnetization, resulting in residual magnetism, which affects door opening. If an accident occurs, it will affect the escape of personnel. Therefore, we design an access control device that can quickly open the door after the magnetic lock is powered off and the magnetic force has not completely disappeared. SUMMARY
