How does a spherical magnetic card lock work?

The two main problems are explained by everyone, the principle of spherical magnetic card lock and the main function of the spherical magnetic card lock.

Magnetic Card: A magnetic card is a card that uses magnetic carriers to record English and digital information for identification or other purposes.

Magnetic card lock:

Magnetic card door locks are also known as access control systems, induction door locks, electronic door locks, and access control attendance systems.

The magnetic card door lock is composed of an access controller, a card reader, a communication converter, an access control attendance software and an electronic door lock. The card reading method is a contactless card reading method. When the cardholder quickly shakes the card near the card reader (5-15 cm), the card reader can sense the card and send the information (card number) in the card to the card reader. The host and the host check the card validity and then decide whether to open the door.

The entire process can achieve access control functions as long as it is within the effective card swipe range. The card reader is installed inside and outside the door wall without affecting its operation. The proximity card is read-only, difficult to copy, safe and reliable, and has a long life (non-contact card reading reduces the mechanical wear of the card to zero). And through the communication converter or TCPI communication adapter and the computer for real-time monitoring (can be issued by the computer to open and close all doors, and can view the status of all doors in real time), data processing, query, report output and so on. The system is suitable for various enterprises and institutions such as post and telecommunications, finance, transportation, building control, community management, parking lots, etc., and has been well received by users for many years.

The main function of the spherical magnetic card lock:

1. Swipe record: When a person enters or exits the door, the card needs to be read before the card reader. After the card reader reads the information, the information is sent to the host. The host first determines whether the information is legal. If it is legal, it issues a door opening command. (That is, send a turn-on signal to the electric lock to open the door; if it is not legal, it will not send the door open designation and can issue an alarm. At the same time, the host will save the card information, date, time and other data for inquiry or directly to the computer for processing.

2. Control Center: The control center can establish employee information through the computer, such as maintenance center, management center, etc., to collect the entry and exit data of each door regularly or in real time, and collect, query, divide and print according to the department. The various parameters of the host can be set by the computer or directly set by each host.

3. Multi-level management: The system can easily realize multi-level management functions. The control center can set the access rights, time range and holiday management of each card through the computer.

4. Attendance: The attendance part is mainly completed by software. Firstly, the user sets up personnel information, shifts, attendance time, holidays, etc., and then downloads the credit card data in the host through the computer communication port for classification, calculation, statistics, and summary, and generates personnel attendance. The report is output by a computer or printer. Beijing Huaxia Classic Technology Development Center is located in the center of Zhongguancun Science and Technology Park. It is a new technology enterprise approved by the Beijing Administration for Industry and Commerce. The intelligent high-tech enterprise integrating R&D, production, sales and engineering has accumulated rich knowledge and experience in the application of automatic identification card technology and intelligent control system for many years.

The working principle of the spherical magnetic card lock:

The residual magnetic induction Br on the magnetic card plays a decisive role in the working process of the magnetic card. The magnetic card passes through the working magnetic head with the coil at a certain speed, and the external magnetic line of the magnetic card cuts the coil, and generates an induced electromotive force in the coil, thereby transmitting the recorded signal. Of course, it is also required that the recorded signal has a wide frequency response, a small distortion, and a high output level during magnetic card operation.
