Among them, the non-contact smart card “all-in-one card” is due to its advanced technology, convenient use, confidentiality and security. More and more widely used in various fields, government agencies, office buildings, smart communities, large enterprises, commercial consumption, highway tolls, campuses, hospitals, etc., identity recognition, parking lot management, access control, passage control, attendance, conference sign-in , Visitor management, personnel information, security patrol, resource management/elevator control, consumption/POS, library management, energy control, etc. are the most commonly used functions.
1.1 Non-contact smart card and multi-information carrier identification
Card identification carrier: The basic carrier for authentication and identification of the one-card system is a contactless smart card. Its full English name is Contactless Integrated Circuit Card, also known as a radio frequency card (proximity card). It is an OR card with storage, encryption and data processing capabilities. Multiple integrated circuit chips and induction coils are enclosed in a standard PVC card, through the data signal of radio waves to complete the access to information, modify reading and writing, etc., and return to the card reader.
Now the commonly used cards include ID cards, IC cards and CPU cards. ID cards have low security and cannot store data. They are suitable for ordinary occasions with low requirements; IC cards have encryption measures, can store data, are highly secure, and are widely used. A card system composed of multiple commonly used subsystems; CPU cards have higher security and are used in a small number of occasions with higher security requirements. Of course, the security of biometrics is even higher.
Multi-information identification carrier: However, with the expansion of the system scale and the requirements for higher-level security and convenience of the system, biometric identification (fingerprints, etc.) with inherent, specific and unique characteristics of the human body, as a more reliable More and more flexible and more convenient authentication and identification methods are used more and more in the card system in combination with card identification, thereby achieving the best combination of high security and return on investment of the entire system. On the other hand, other identification types of information carriers such as RFID electronic tags, vehicle number scanning, various active or passive cards, etc. can also be combined and used in the same system, so that managers and users are no longer limited to one type. Information identification carrier, which greatly realizes the flexibility and convenience of use and management.
1.2 Smart Access Control System
The OPEN smart access control system is an application subsystem under the OPEN one-card system. It refers to the installation of smart card electronic automatic identification systems at the entrances and exits of buildings based on modern electronics and information technology. ) The intelligent management system that implements release, rejection, recording and other operations, its purpose is to effectively control the entry and exit of personnel (items), and record all the details of the entry and exit, and realize the safety management of the entrance and exit.
No matter what kind of non-contact smart card or biometric (fingerprint, etc.) is used in the OPEN access control management system, automated management can be achieved, depending on the capital investment, functional requirements, and matching conditions with other systems.
The OPEN intelligent access control system monitors and manages each controller through a computer. It adopts 485 communication interface and supports TCP/IP protocol. In a system with multiple access control points, a dedicated communication line can be used to form a dedicated system network, and the communication with the computer can be realized by RS232/485 signal mode. It is also possible to use the Lan local area network lines established within the community or modern enterprises and groups to integrate the access control system into the local area network or close to the Internet. There is no need to set up another line network to control different access control in the same system at any place in the world. Point to achieve remote management and control.

Holders of a valid card can easily enter and exit the doorway.
People without a card or with an invalid card cannot enter and exit the doorway.
There are emergency measures for abnormal situations.
The detailed entry and exit records of someone at a certain time can be easily inquired through computer software.
Managers can control the access rights of each card at any time.
Economical and reasonable operating costs.
3.2 System design principles Advancement
The construction of the OPEN access control card system must be based on today’s internationally advanced and promising technology that represents the mainstream trend, and the system thus realized can be smoothly upgraded with the development of future information technology. For example, the network communication in the all-in-one card system adopts the internationally popular TCP/IP protocol, the server and workstation adopt the Microsoft Windows operating system, the database adopts Microsoft’s SQL Server large-scale database system, the front-end application program is developed using Delphi, and the system has C/S Combine the platform with B/S.
Practicability: The OPEN access control card system should fully understand and analyze the user’s various management modes and characteristics, and the development of each application system should be fully functional, convenient to use, technologically humanized, economical, reasonable, practical, and efficient. At the same time, targeted designs and flexible solutions can be made for specific needs and actual conditions of on-site engineering.
Security: The design of the OPEN system is highly reliable, and the product has mature and stable performance, ensuring long-term trouble-free operation of the system, ensuring the accuracy, integrity and consistency of the data even after an accident is interrupted, and it can be quickly restored normal. Security can only be ensured by ensuring reliable and stable system hardware. The OPEN software system has strict management and operator authority control. It has alarms and log records of various operations, which effectively prevents internal cheating. The software can cancel the authority of reporting lost cards and blacklisted cards in real time to prevent fraudulent use and abuse of cards, and ensure The security of the entire system is improved.
OPEN system uses encrypted card number (to prevent security vulnerabilities such as duplicate cards and imitation cards)
The OPEN system uses the encryption function of the IC card. The identification of the card is not the serial number of its own card chip but the card number that the user defines and writes in encryption when the system is issuing the card. Each system uses a unique password to encrypt and issue the card. This system reads and writes the card. The device only recognizes the cards issued by the system, completely eliminating the potential safety hazards caused by repeated card serial numbers or low-order repetitions of card serial numbers.
The communication between the OPEN system card reader and the access control host is a self-defined encrypted communication method to prevent unauthorized persons from using other card readers to replace the original card reader to transfer data to the host illegally opening the door.
The card amount encryption password in the OPEN one-card consumption system is set by the user when the system is activated, which effectively prevents illegal recharging and cheating, and effectively guarantees the user’s safety and interests.
Scalability: The OPEN access control card system can not only meet the needs of current users in terms of capacity and functions, but also easy to expand due to the standardization and open compatibility of the system to ensure future expansion and upgrades of users. The system can be added to existing systems at will The control equipment of the new system can also be added to form a larger all-in-one card system.

Multi-level watchdog circuit design prevents crashes.
Using American original built-in battery chip, data and clock will never be lost.
(2) Linkage function
Security linkage: When the door is opened (including illegal intrusion, the door lock is broken), the linkage monitoring system is activated to send out real-time alarm information.
Linkage of lights, etc.: When the card is valid, the lights of the corresponding area are automatically turned on
Fire linkage: When a fire alarm occurs, the corresponding area channel is automatically opened
There are three ways to implement this function:
1. The access control point adopts AC220V AC bus power supply, the main power switch controlled by the relay, the normal switch is in the closed state, and the system is normally powered. Once a fire alarm occurs, the alarm signal drives the relay to turn off the power switch, and the doors controlled by this switch are all off. The electricity is turned on automatically. This is the most commonly used, most effective, most reliable and easiest way. The electric lock adopts a normally open electric lock that is switched off when the power is turned off. The access control system can also be equipped with a power bus for full control or according to the partition of the fire signal. To achieve sub-regional control, the schematic diagram of linkage control is as follows:
2. The fire-fighting linkage signal is directly connected to the access control host in the area through wiring. When a fire alarm occurs, all relevant doors are automatically opened. This method requires additional wiring.
3. The fire-fighting linkage signal is input into the access control computer software, and the software controls all doors to be opened. This method requires the software to be running all the time, and the fire-fighting system must provide related interface protocols.
(3) Centralized management
The management center uniformly sets, changes, cancels, and restores personnel access rights.
The management center can remotely control the door to open.
The management center can monitor the status of each door and personnel access in real time.

There is no local management computer at the access control point, and it is managed by the remote center management workstation through the Internet or wireless communication.
4.4 System workflow
A. The flowchart is as follows:
B. Work flow:
1. The administrator sets basic information such as channels and personnel in the management software.
2. The administrator issues a card to each person and authorizes each person to enter and exit at which doorway and time period.
3. When entering the door, the cardholder uses a non-contact card to sway in front of the card reading area of the access control machine. After the access control machine confirms the identity, open the electric lock to open the door, and the door is closed after the person enters.
4. When going out, the cardholder swipes the card or presses the exit button, the door opens, and when the person goes out, the door closes.
Chapter 5 Equipment Introduction (omitted)
Chapter VI Introduction to Management Software
The OPEN access control system is an integral part of the all-in-one card management system. The program login account must be added by the administrator in the system management program. Operations such as reporting the loss and unhooking should be carried out in the system management program. The main window can monitor the status of each access control point and whether it has alarmed in real time. When an alarm signal occurs, the system automatically pops up an alarm interface.
The main interface of the high-end access control subsystem software is as follows. The main interface of the system is the real-time monitoring interface, which can monitor the status of each door, personnel entry and exit conditions and photos (the photos of personnel can be displayed in an enlarged size). In some special doors or special time periods, it can be realized that after the cardholder swipes the card, the system will display the cardholder’s information and photos and will not open the door temporarily. The duty officer will give the door open signal to allow entry after confirmation.
Multiple real-time monitoring of high-end access control software: Choose OPEN high-end access control software, which has multiple real-time monitoring functions. Multiple terminal computers can monitor the status of each door and real-time personnel access in real time according to levels, regions and nesting. Local real-time monitoring and management of access control points in area A, computer B monitors and manages access control points in area B locally, and multiple simultaneous real-time monitoring and management of access control points in areas A and B can be performed on the computer in headquarters or general control center C at the same time. In addition An administrator with a valid account and password can log in to the OPEN access control software on any D computer in the TCP/IP network, and then they can simultaneously monitor and manage part of the access control points that are authorized in real time (it is possible to authorize the monitoring and management of a part of the access control points in Zone A). Part of the access points in Zone B) or all access points. If someone enters or exits a door in area A, the related multiple monitoring computers A, C, and D can simultaneously display the name, time, photo and other information of the person entering and leaving; if an alarm occurs at a door in A, the relevant Multiple monitoring computers A, C and D computers can simultaneously pop up an alarm processing box, accompanied by voice prompts. The diagram of the multiple real-time monitoring system is as follows:
This high-end function has three major use cases: 1. Nested management of headquarters and branches, each branch independently manages local access control points, and the headquarters performs unified management and control on this; 2. Managers can use their own office computers or other Real-time monitoring, control and management of access points can be completed by using a legal account and password to log in to the access control system on any computer, without having to go to a server or a fixed management computer that communicates with access control hardware; 3. High security such as prisons or banks Locally, in order to prevent omissions, multiple monitoring centers have been established to monitor and manage the access control system simultaneously. Once an intrusion or other alarm occurs, multiple monitoring centers can simultaneously receive the alarm signal in real time to ensure that the alarm is handled in a timely manner.
Access control period: A period of time refers to a passable interval. A day can be divided into six periods, and each period is independent of each other. When authorizing access rights, you can select the time range of authorized personnel in these six periods.
Holiday setting: 30 days of holidays can be preset. And according to the unit system to set whether Sunday, Saturday, and Saturday afternoon are holidays. When authorizing access rights, you can choose whether to allow normal passage during holidays. If a five-day work system is used, Saturday and Sunday are both holidays.
Entry and Exit Authorization: Entry and exit authorization is mainly to set when each person can enter and exit those passages or at which passages to perform patrols (can swipe the card but cannot open the door). You can choose to authorize by personnel or by channel. If authorized by personnel, the personnel will be displayed on the left, the door passage and authorized time allowed for this person are displayed on the right side, and the door passage forbidden by this person is displayed on the right side. Perform the same operation to change the authority of this person. Click the time period to set the specific time period and holidays that the selected person is allowed to pass on the selected channel. Before the specific time is set, the default is to pass at any time.
Electronic map: This interface is for map input and picture replacement or deletion operations. The map supports various picture formats (jpg, bmp, etc.), and the system supports multiple maps.
Access control distribution: The access control distribution is to mark each access control point correspondingly on the corresponding map.
Real-time monitoring: The real-time monitoring of the electronic map mode directly shows the status of each door on the map. The background color of the access control point is red to indicate abnormal communication, green to indicate normal communication, and yellow to indicate that there is an alarm at this point. You can perform operations such as zooming out, zooming in, dragging, slow screen, and original image size for each map.
Channel status: The channel status can be used to query whether the channel is normally open, normally closed or normal, as well as the arming status of the channel and whether it is alarmed or not.
User information: The user’s files can also be briefly searched in the access control subsystem, which is convenient for personnel to check and manage at certain times.
Entry and exit query: The entry and exit query mainly queries the entry and exit records of personnel, and the top is the query condition, which can conveniently query the entry and exit status by number, name, card number and entry and exit time range, and can export the entry and exit records of any day to which day to Excel File.
Alarm query: Alarm query can query all alarm record information by channel, event and time.
System event query: You can query the operation, control and corresponding time of the operator on the access control machine.
