Principle and introduction of electronic access control

Introduction: With the development of science and technology, the application of high-tech has been popularized in people's lives. With the fully automated production process, people's lives are becoming more and more automated, and electronic products are becoming more and more popular. Electronic access control system is not surprising. Electronic access control system is applied in both scenic spots and high-end occasions. So how do these access control systems work? I believe there are many interested friends who can't read fast, so cut the crap. Let's share the working principle of the electronic forbidden door with you!

Electronic entrance guard is a control network system consisting of a controller, an information collector and an electric lock with CPU as the core. Through the information reading and processing of the system, the automatic control of various door lock switches can be realized. According to the way of information reading, it can be divided into: card type, induction type, image recognition type, eye iris recognition type and so on. Their scientific and technological content and system cost order increase in turn.

working principle of access control: induction cards are generally called contact cards, and magnetic cards should be swiped to achieve control purposes. Usually, an induction card contains an IC chip, an induction coil and a capacitor element. The inductive card is the transmitting and answering end, while the inductive card reader is the receiving end, similar to a generator, which continuously transmits the frequency. When the card is close to the emission frequency range of the card reader, the coil in the card will receive this frequency and generate energy, and this energy will be stored in the capacitor. When the energy reaches the excited state, the password burned on the IC chip in the card will be sent to the card reader for identification, and then the door can be opened. The frequencies emitted by the card readers of various brands in the market are different, so the cards will not be interoperable and usable.

the main purpose of setting up the access control management system is to ensure the safety of the equipment in the above-mentioned areas and facilitate the rational flow of personnel, and to manage the access permission of personnel entering these important areas in various ways in order to restrict the personnel from entering and leaving at will. When employees want to enter the controlled area, they must swipe their cards in the card reader next to the door before the door can be opened. The card reader at each door is controlled by the monitoring terminal through the field control interface unit and the system centralized controller. According to the system settings, each card can only open the door within the specified range within the specified time. At the same time, prevent outsiders from breaking in casually. If someone forcibly breaks the door or leaves the door open after work, the access control device will send out an alarm signal, and the alarm door number will be displayed on the monitoring terminal immediately. The purpose of access control system design is to realize the control of personnel access rights and the recording of access information. I believe that after the above description, readers have a perceptual understanding of the principle of access control system. Entrance guard safety management system is a new modern safety management system, which integrates microcomputer automatic identification technology and modern safety management measures, and it involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, biotechnology and so on. It is an effective measure to solve the problem of the entrance and exit of important departments and realize the security management. Suitable for all kinds of confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories and so on.

practicability of access control system: the function of access control system should meet the actual needs, not flashy. If we unilaterally pursue the system's advance, it will inevitably lead to excessive investment and deviate too far from the actual needs. Therefore, the practicability of the system is the first principle that should be followed first. At the same time, the front-end products and system software of the system have good learning habits and operability. Especially operability (convenience), so that managers with primary computer operation level can master the operation essentials of the system through simple training and reach the operation level of completing duty tasks.

did everyone understand it after reading it? There are so many high-tech applications in the electronic forbidden door. The power of science is great. Remote control information technology has already occupied the mainstream of the world. Friends who like scientific research pay more attention to the development of the latest technology and watch more programs about technology. I hope everyone will study scientific knowledge seriously, don't be illiterate in the 21st century, and be a high flyers in the 21st century. Rabbit will stop here. Thanks for watching.
