Basic composition of access control system

Identity recognition unit is an important part of access control system, which plays the role of identifying and confirming the identity of passers-by. There are many ways and types to realize identity identification, including card identification, password identification, biometric identification and composite identification. Target recognition biometric fingerprint, palm, fundus print, iris, vein, face, voice, signature, gait, etc. Common electronic locks and execution units such as keyboards, disordered keyboards, barcode cards, magnetic cards, ic cards, induction cards, metal objects, magnetic objects, explosives, radioactive substances, special chemical object code identification barcodes, ESA labels, QR codes, etc. include various electronic locks. There are many types and types of electronic locks, which can be divided into plug-in lock, magnetic lock, cathode lock, anode lock and shear lock according to different working principles, and can meet the installation requirements of various wooden doors, glass doors and metal doors. Each electronic lock has its own characteristics, and there are also differences in safety, convenience and reliability. It is necessary to choose the appropriate electronic lock according to the actual situation. Control actuator The access control actuator executes the control command sent by the access control management subsystem, and makes corresponding actions at the entrance to realize the rejection and release operation of the access control system. Common controlled devices such as electric locks, car stops, alarm indicating devices, electric doors and other controlled objects. Management setting unit mainly refers to the management software of access control system, which can run in Windows2000, 2003 and XP, support the working mode of server/client, and authorize and manage the operation functions of different users. Management software should use large databases such as Microsoft SQL, which has good developability and integration ability. The management software should have the functions of equipment management, personnel information management, badge printing, user authorization, operator authority management, alarm information management, event browsing, electronic map and so on.

What is access control system and access control power supply?

Access control system, as its name implies, is a system to control access, which is developed on the basis of traditional door locks. The traditional mechanical door lock is just a simple mechanical device. No matter how reasonable the structural design is, no matter how strong the material is, people can always open it by various means. It is troublesome to manage keys in crowded passages (such as office buildings and hotel rooms). If the key is lost or replaced, the lock and key should be replaced together. @ @ @ @ Chengdu Xin 'an/access control power supply is necessary when installing access control, because the power supply is for the magnetic lock and access control host. . . .

What does intelligent access control system mean?

First of all, the traditional building access control system has several pain points. First, the construction cost is high, because every household has an extension, and the links are limited, and the cost of equipment, auxiliary materials and engineering is high; Secondly, due to the large number and complexity of these intermediate devices, it is easy to cause signal interference, resulting in a very high failure rate. After 3-5 years, most systems are paralyzed or semi-paralyzed. Third, the later maintenance is complicated. Because the line is buried through weak current wells, the cost of later investigation is high and complicated, and the engineering quantity is huge.

Intelligent access control system adopts Internet of Things technology, cloud computing, 3G wireless link, no weak current wiring, which solves the problem of signal interference, reduces the cost, and is more green and environmentally friendly. At the same time, the later maintenance is relatively simple, and troubleshooting becomes easy. It can also be managed and upgraded online, making remote maintenance more convenient. At the same time, the function expansibility is relatively strong, and it can be extended to the direction of home intelligent security, smart home and smart community.

Intelligent access control system can open the door with mobile phone, call the door and swipe the card to open the door. You can open the door with mobile phone by downloading a smart dog App on the mobile phone, which is intelligent, safe and convenient.

What is an access control machine?

According to the communication mode with computer, access control system can be divided into independent access control system and networked access control system. The independent access control system can't communicate with the computer, so you can set the access control authority on the keyboard or mother card of this machine. There are also some independent access control machines that are authorized to make cards, such as auxiliary keyboards with LCD display. Independent access control system consists of independent access control machine (including card reading and control)+door opening button+electric lock+power supply+sensor card, and some can also be connected with a card reader to realize card swiping when entering or leaving the door. The advantage of the common independent access control system in the market is that it is relatively cheap, and the decorators can install it without computer knowledge. Disadvantages of independent access control system: poor security. Because the relay controlling the electric lock is in the integrated machine, criminals can open the door by short-circuiting or destroying the independent access control machine without much professional knowledge, and some can even attract the relay in the independent access control machine by strong magnets to open the electric lock. Although some manufacturers have made improvements and put buttons and relays in the power supply, they have not fundamentally improved the safety factor. It is quite inconvenient to set the permissions of the card. If a company has multiple doors that need access control, it needs to be set and cancelled one by one. The setting work is quite troublesome, and I don't know which doors have set what permissions. Therefore, the independent access control system is suitable for occasions with low security level (preventing gentlemen from guarding against villains), low cost budget and few doors, and it is not necessary to quickly authorize and analyze access control records. The networked access control system can communicate with the computer, and the access control management software installed on the computer can set the authority of the card, analyze and query the access control records. When the computer is not turned on, the system can run normally offline. Software operation can set permissions and parameters, and can monitor the entrance and exit of each door in real time. You can count attendance reports, etc. The networked access control system consists of access controller+card reader+exit button+communication hub+sensor card+power supply+access control management software. Note: If two card readers are connected, you can swipe your card in and out. If you connect a password reader, you can realize the card+password function to prevent the card from being picked up by others and illegally entering. The security level is higher. The biometric device with the output format of wiegand26, the international communication interface of the card reader, can replace the card reader to connect with the controller to realize a higher security access control system. According to the communication mode of access controller, it can be divided into 485 networked access control system and TCP/IP networked access control system. The typical 485 network access control system is a typical TCP/IP network access control system. Note: Besides RS485 and TCP/IP, there are other access control systems with bus structure, such as LAN bus. Because these products are few in the market, each has its own advantages and disadvantages, so I won't describe them in detail here. Advantages of networked access control system: high system safety factor, good cost performance, powerful function and convenient operation. Through the analysis and management of credit card record data, value-added functions such as attendance can be derived. Among them, TCP/IP network access control system has more advanced technology, faster communication speed, wider networking scope and more stable communication. Because the price is slightly higher than the 485 network access control system, its popularity is not as good as the current 485 network access control system, but it will surely become the mainstream of the network access control system in the near future. At present, the mainstream and trend of access control system is network access control system, which is the first choice for users in middle, high-end, high-end, middle and low-end areas. What is an access control machine? The so-called integrated access control machine is an access control product that combines card reader and controller, which is independent and networked. Compared with the networked access control system with separate card reader and controller, its cost is lower, but because the control part is exposed and the security level is slightly lower, it is mostly used for users with only one access point in some companies. Most large and medium-sized multi-door access control systems will adopt networked access control system with card reader and controller separated to meet the stability and security requirements of middle and high-end access control users. All-in-one machines are often equipped with keyboard settings and LCD display, which can meet the appearance requirements of some domestic customers. However, because LCD is a fragile accessory, its stability and anti-interference will not be as good as those of networked access control products with card reader and controller separated, and imported products (except some products in Taiwan Province Province) ... >>
