chrispeng [ad_1]
Chongqing Jiangbei International Airport is one of the three major aviation hubs in Southwest China and one of the five major hub airports planned by the state in the future. It is a 4E-class civil airport. The airport currently has three terminals, namely the T2A and T2B terminals for domestic flights and the T1 terminal for international flights. The domestic terminal has a construction area of 171,000 square meters and a designed annual passenger throughput of 20 million.
1.Project summary
The access control management system of Chongqing Jiangbei Airport (referred to as the access control system) refers to the comprehensive entrance and exit management system that controls the entry and exit of personnel according to the settings of the permissions for the entry and exit of personnel in each area of the T2A terminal and the international building of Jiangbei Airport at different times.
At the same time, the access control management system of this project requires that the access control system that has been put into operation in the T2B terminal building be brought into unified management, and its built access control system should be modified and upgraded according to the overall requirements. In this way, a unified access control IC card (employee card) and a unified database are used in the access control system of the T2A terminal, T2B terminal, and international building.
This project uses the internationally renowned brand Mengyili MeLucky®MACAS3000 large-scale access control and integrated security management system and equipment. The system has been used in dozens of large-scale domestic and foreign airports, such as Tianjin Airport, Xiamen Airport, Capital Airport, Taiyuan Airport, Urumqi Airport, and Angola Capital Airport. Successfully applied in airport projects.

3.Basic structure and configuration of the system
Chongqing Jiangbei International Airport adopts a networked access control system. The newly built T2A terminal access control system will be integrated with the new access control system of the international building and the original access control system of the T2B terminal through the internal local area network.
In order to reduce construction costs and management costs, improve management efficiency, and truly reflect the principle of “centralized management, decentralized control”, through the T2A terminal access control system management server and card issuing terminal equipment, the entire system The hardware equipment (the access control points under the jurisdiction of the International Building and T2B terminal) realizes parameter configuration, personnel authorization, real-time monitoring of access control events and alarm events, historical record query, remote control of the opening or closing of doors, etc.
Based on system security, the system is equipped with two management server hosts to realize one-master and one-backup dual-system backup.
In the international building and T2B terminal, computers are respectively configured as management workstations, which can independently realize personnel authorization, real-time monitoring, historical record query, and remote control of the opening or closing of doors in the area. At the same time, if the corresponding authority is granted, the device parameter configuration and personnel authorization can also be performed on the access control points in other areas.
The access control system is mainly composed of the control part of the management center (management server, card issuing terminal, area controller, etc.), data transmission part, and field part (entry and exit including card readers, field controllers, electric locks, etc.).
The area controller communicates with the management server through TCP/IP communication, and is connected to the front-end field controller through the RS485 bus.
Each access control point adopts two-way card swiping to strictly manage the entry/exit method (the identification of each card reader is through the dual identification of the proximity card and the personal password).
The system architecture is as follows:
4.Overall system function and performance
Safety management
Multi-level personal password login method to verify the authority and security of system administrators;
Improve access control event display and alarm management, prompt online prompts and alarms for unclosed doors and illegal openings, and notify the security department to deal with it;
Multiple approved door opening methods, including card only, password only, card plus password, card plus video double verification, etc.;
Supports three-level data/information storage and management of servers, area controllers, and field controllers. Once a certain level of equipment is paralyzed, it will not affect the normal access control management and the smooth passage of personnel. After the system is restored, all data will be automatically uploaded to achieve “centralized management,” The principle of decentralized control.
The access control controller supports ring dual bus. When a certain point of the bus is disconnected, the normal communication of all devices will not be affected.
Support dual-system hot backup to ensure data security.
Operator management
A variety of operator operation levels can be set, and the degree of operation can be defined. Each operator can only operate a limited module within the authorization range, and each step of operation will generate a record and store it in the event library.
Equipment management
The control center can set, monitor, and control various parameters and equipment status of each entrance and exit controller in the graphic mode.
Incident management
All operator events, access control events and various fault information are classified and processed and stored in the database.
Alarm management
In addition to faults and common alarms, the operator can also define some other event as an alarm event. When an alarm occurs, the corresponding auxiliary equipment can provide sound, light and voice prompts.
Personnel registration and issuance
Management functions such as local card issuance, authorization, loss reporting, visiting card registration, and blacklist.
Real-time monitoring of equipment status
Automatically detect the working status and failure conditions of communication channels, front-end controllers, card readers and other equipment, and have alarm prompts to remind staff on duty.
