What is the working principle of access control electronic lock?

1. Principle of electric plug-in lock. Electric plug-in lock is also called "anode lock". In fact, it is just a kind of "anode lock", which is an electric lock that cuts off the power and opens the door. Because according to the fire protection requirements, when a fire occurs, the building will automatically cut off the power supply, and the electric plug-in lock should be opened to facilitate people to escape, so the performance of the electric plug-in lock is to cut off the power and open the lock (open the door).

2. The principle of simple electromagnetic induction generates a magnetic field when it is energized, and the magnetic lock generates magnetic force to absorb another piece of iron plate. The electric plug-in lock is to generate magnetic force when it is energized to push the pin down.

3. Electronic lock is an electronic password lock, which is an electronic product that controls the circuit or chip work (access control system) through password input, so as to control the closure of the mechanical switch and complete the unlocking and locking tasks. There are many kinds of it, including simple circuit products and chip-based cost-effective products.

4. Abstract: Electronic combination lock is a kind of electronic product that controls the work of the circuit or chip through password input, so as to control the closure of the mechanical switch and complete the task of unlocking and locking. There are many kinds of it, including simple circuit products and chip-based cost-effective products.

5. What is the principle of smart lock? 1 The working principle of smart lock. Only by knowing the working principle of smart lock can users better understand it. The basic structure of the intelligent lock is to use the motor to drive the mechanical lock cylinder to complete the original manual rotation of the key.

6. · Principle of access control system Principle of independent access control system Independent access control is non-network type. Each door lock is independent, and its information reading is usually card-type and induction type.

Electronic access control principle and introduction

Access control controller is a digital management system for managers entering and exiting. Common access control systems include: password access control system, non-contact IC card (inductive IC card) access control system, fingerprint iris palm biometric access control system, etc.

Magnetic lock principle We know that each magnet has two poles, one North Pole (N pole) and one South Pole (S pole). Magnets have the characteristics of same-sex repulsion and opposite-sex attraction. Electromagnetic locks take advantage of the characteristics of magnets. Locks made of permanent magnets (magnetic beads) are also called "electronic locks".

The principle is that the controller accepts the personnel information and the corresponding authorization information sent from the management computer, and at the same time transmits the card record of entering and out to the computer. A single controller can form a simple access control system to manage one or two doors.

First of all, let's talk about the similarities between the principle of IC card and fingerprint unlocking: compare the read identity information with the information in the system (previously registered). If it is the same, it means that the identity is correct, and the corresponding actions are performed, such as opening the door lock.Differences: 1. IC card.

Introduction to the principle of access control system To understand the principle of access control system, you must first know the hardware composition of the access control system. Access control system hardware includes: multi-function scanner, host, controller, motor, transmission device, sensor, each of which has its own important role.

The access control system is an indispensable part of the intelligent building security automation system, and it is also one of the necessary systems for all intelligent buildings. According to the latest intelligent building design standards, access control system, anti-theft alarm system, closed-circuit television monitoring system and electronic patrol system together constitute the main part of the intelligent building security system.

Working principle of access control system

Working principle of access control system. The access control system supplies power through the access control power supply, and the access control lock executes the signal of opening and closing the door.The access control controller is responsible for receiving and storing various complex functions such as receiving and processing all access control. The working principle of access control is different for different identification methods. The working principle of swipe card access control is to use induction.

The network access control system is composed of controller, card reader and electronic lock. The door opening button is composed of the underlying control layer and execution layer of the system integration. ( 1) Controller: It is used to collect information from the card reader for processing, issue instructions, and control the opening of the electronic control lock; memory sensing card data: complete the bus networking function, etc.

Their technological content and system cost order increase in turn. Working principle of access control: induction cards are generally called contact cards, and magnetic cards must have the action of "swiping" when used to achieve the purpose of control. Usually, there are IC chips, induction coils and capacitors in an induction card.

The working principle of wireless communication (induction) IC card access control system Induction technology, also known as wireless frequency identification (RFID) technology, is a method that can read the information on the card without direct contact between the card and the card reader.

The access control system has long gone beyond simple doorway and key management, and it has gradually developed into a complete access management system. It plays a great role in administrative management such as work environment safety and personnel attendance management.

Design scheme of access control system and principle of access control system

1. If the access control system adopts the networking method of 485 LAN, it needs to adopt twisted pair shielded wires, in order to ensure the communication stability of the system, if the access control system adopts the TCP/IP communication method, the super 5 network cable is selected as the communication cable to ensure the normal communication of the system.

2. The access control system is a subsystem of the entrance and exit management system. Usually, it adopts swipe cards, human biometric identification and other technologies. Under the control of management software, it manages the entrances and exits, allowing those who are qualified to enter and exit to pass freely, and interferes with those who should not enter and exit.

3. Access control, also known as access management control system, is a digital management system that organically combines information technology, electronic technology and mechanical locks to identify the appropriate level of authority of entry and exit personnel and carry out corresponding control.

4. The purpose of the design of the access control system 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 sensitive understanding of the principle of the access control system.

Access control system principle door magnet principle analysis

Door magnet is a sensor that detects the switch status of the door. If the door magnet is installed, the switch action of the door and the state of the door can be seen on the management computer of the local area network. Similarly, if It is the remote Internet control management, and you can see the opening and closing action of the door thousands of kilometers away and the status of the door. If the user doesn't need it, it can be installed without it.

The function and working principle of the wired door magnetic sensor. In the smart home access control system, the function of the door magnetic switch is to be responsible for whether the door magnet is connected or not, the power is turned on and magnetized (closed the door), the power is cut off and demagnetized (open the door), and the door magnetic securityIt is installed on the door and door cover, and the switch is installed in the house. It is used with an automatic door closer, which can generally withstand a pulling force of 150 kilograms.
