Access control management subsystem program
1 Access control system requirements
According to the requirements, the areas controlled by the project include: important entrances and exits of the building, elevator forecourt doors, various communication rooms, various equipment rooms, leadership offices, financial rooms, confidential confidential rooms of various departments, personnel archives, important warehouses, and central control rooms , Security center, etc., and cooperate with the linkage function of the fire protection system, TV monitoring system, and intrusion alarm system to achieve the greatest sense of machine defense protection.
1.1 Distribution of access control points
For specific points, please refer to the system point table.
3.2 Introduction to the functions of the access control system
The entrance and exit access control management system refers to the management of the entry and exit points in the building to reduce risks and improve the level of safety, especially during working hours (daytime) and holidays. It not only replaces the mechanical lock opening/closing action in the traditional sense, but also increases the recording function. It is also a diversified management tool. A large number of access control operations can be managed through convenient and quick operating procedures.
The access control system is an important part of the all-in-one card system, and it is also a core subsystem of the integrated defense system for intelligent buildings. Therefore, in addition to exchanging information with the card issuing center, the access control system must be integrated with the TV monitoring system, access control system, intrusion alarm system, patrol system, and intelligent management (BMS) system, interactive linkage and organic coordination, forming a deep A multi-level and omni-directional security protection system, so that the centralized management and monitoring of the surrounding and internal order and safety of the building can become a unified command, unified dispatch, and unified police handling.
Its main functions include:
Area management
According to the requirements of building security technology, the access methods in restricted areas can be designed such as: single card, dual card, card + password, card + fingerprint (palm print, iris, etc.), and the opening/closing characteristics of the door lock.
Special function
The system can be equipped with advanced functions such as anti-passback, interlock, duress code, limit the maximum and minimum people, and selectively view the distribution of people in the building according to needs.
Time zone management
With multiple programmable time zones, each time zone can define “start time”, “end time” and valid days of the week.
Holiday arrangement
Holidays throughout the year can be pre-programmed, all usual functions are automatically blocked during holidays, and holiday procedures are automatically executed. Cardholders can only enter and exit the protected area through specific channels and within specific time zones.
Card authorization management
Through the pre-programmed settings of the card type, area and time zone of the card issuing center, the system can authorize the cardholder’s pass card (access/exit level setting), and set the valid use time and range of the card (allowed entry area).
Central monitoring
The management host can monitor the on/off of the electric locks of all access control points in real time, and display the switch status of all access control points in real time with multi-level electronic maps and tables, and can view the time, date, card number and name of the person entering and exiting each time the door is opened in detail , Affiliated department, position, personal portrait and other information. Central on/off control of single door, part or all door locks can be carried out.
digital map
The management workstation software has a map generation tool module, and users can easily generate and edit electronic maps. Maps can also be made from AutoDesk® AUTOCAD (R14/2000) engineering drawing files (*.dwg, *.dxf, *.dwz) or other graphic files (*.jpeg, *.jpg, *.bmp, *.wmf, *. pcx, etc.) are automatically converted, and graphical editing tools are provided to adjust the map.
Operational objects such as controlled doors and alarm buttons are shown in the form of icons in the corresponding positions on the map. The static properties of various objects should be automatically displayed when selected in the form of electronic tags. These static properties should at least include the position of the object , Label number, status, etc.
The control, pattern, command button or floor plan zoom button provided by the icon can be connected to execute unlimited floor plans and arbitrary zoom. The color of the icon changes and flashes according to the real-time situation.
Alarm function
When there is an unregistered card in the system, the authority does not match, the door is not closed, the power supply and the communication line are faulty or damaged, the monitoring center will receive an alarm signal. The personnel on duty can find out the cause and location of the alarm through the monitoring terminal or the management host, and can take corresponding measures immediately.
When an alarm occurs, the map area centered on the alarm point is displayed at a specified scale, and information related to operations and alarms and the image of the licensee are popped up. The operator fills in the treatment measures and treatment results, and closes the window. The system should be able to automatically record the processing measures and processing results entered by the operator on the workstation in the file server.
Record and query
Every event in the system is recorded in detail, such as the time when the door lock is opened and closed, the number of the door open card, the reason and location of the alarm input, etc. These recorded information can be shared under certain conditions and provided as raw data to other related systems with good compatibility.
Report management
The system can record all incoming and outgoing events, alarms, and faults, and classify them as needed to form annual, monthly, and daily reports.
Linkage control
Linkage with CCTV television monitoring subsystem
Linkage with intrusion alarm system
Linkage with fire alarm, bandit police automatic alarm system
Linkage with the lighting of the building equipment monitoring system
Linkage with elevator management
Linkage with Intelligent Management (BMS)
Safety management
The system has strict login management for administrators and operators, and has complete log, data backup, anti-tampering and anti-destroy measures.

1.3 Schematic diagram of access control system
The access control system is composed of a control host, an inductive card reader and an electric lock (plus a computer and a communication converter when connected to the network). The card reading method is a non-contact card reading method. The cardholder only needs to place the card near the card reader (10 cm) Shake once, the card reader can sense that there is a card and send the information (card number) in the card to the host. The host checks the legitimacy of the card, and then decides whether to open the door. The access control management function can be realized in the whole process as long as it is within the effective credit card range. The card reader is installed inside and outside the side wall of the door without affecting its work. The induction card is not easy to be copied, is safe and reliable, and has a long life (non-contact card reading method reduces the mechanical wear of the card to zero). And through the communication adapter (RS485) and the computer for real-time monitoring (all doors can be opened/closed by the computer, and the status of all doors can be viewed in real time), data processing, query, report output, etc. All data of the access control system are stored in the central server.

Interface Description
Interface relationship with CCTV system
When an event occurs, the access control system can issue instructions to the CCTV system to respond in three ways, display the on-site situation on a specific monitor, and record the on-site situation as needed.
The first method is to use the TCP/IP protocol to send instructions to the CCTV system through the computer network to achieve linkage;
The second way is to send commands to the CCTV system matrix through TCP/IP to achieve linkage;
The third way is to send a signal to the main access controller or sub-controller of the CCTV system through multiple output ports of the access control device to achieve linkage. At the same time, the access control system provides the address to the CCTV system, and the CCTV system can display the alarm point on its multimedia computer screen. The access control system can also display and monitor by importing the CCTV system picture into the management host. The access control system can be connected with multiple CCTV systems, and can be linked according to the reserved interface provided by the CCTV manufacturer.
Disaster prevention alarm interface
There are two ways to link the fire protection system and the access control system:
Dry contact opening method: The fire system will send an alarm signal to the on-site access controller of the access control system in the form of a dry node. When the on-site access controller receives the signal, it unlocks the controlled door lock. Because the access control system has a fire-fighting linkage function. Therefore, the doors can be opened in time after receiving the signal.
Dry contact linkage method 1:
Dry contact linkage mode two:
Command opening method: After the access control system management software receives the fire protection protocol signal of the fire alarm access controller of the fire protection system, it will open the corresponding door lock according to the pre-planned escape route.
Protocol instruction linkage mode:
The system has a professional interface with disaster prevention and alarm, which is used to receive the alarm information sent by the FAS system and perform corresponding linkage. The interface adopts the form of software, seamlessly connects with FAS system software, and directly receives various related alarm information.
When a fire alarm occurs, the above three linkage modes can be carried out at the same time to ensure that all access doors are opened quickly in the event of a fire alarm to ensure the safe evacuation of personnel.
