With the accelerated development of smart buildings and digital parks, building entrances and exits are no longer just a "door opening and closing" device, but have become key nodes in the entire intelligent system. As the core component of entrance and exit control, the intelligence and system integration capabilities of automatic doors are gradually becoming the focus of Party A's bidding.
Modern automatic doors not only achieve "inductive opening and closing", but can also seamlessly connect to core building subsystems such as access control systems, fire protection systems, and security systems, truly realizing the modern building needs of "multi-system linkage, centralized management, and on-demand response".
1. Access to the access control system: realizing intelligent identity management and authorized access
The linkage between automatic doors and access control systems is the most typical integrated application in scenarios such as smart offices, government buildings, and industrial parks:
Card swipe/face/fingerprint control to open the door: Combined with multiple identification methods such as IC cards, face recognition, and QR codes, automatic doors are only open to authorized personnel;
Automatically record entry and exit time and passage trajectory: Automatically upload data to the background every time the door is opened and closed, which is convenient for enterprises or managers to track records;
Flexible authority settings: authority allocation and automatic opening and closing control can be performed according to departments, time periods, floors, holidays, etc.
For suppliers, automatic door controllers that support standard access control protocols (such as RS485, Wiegand, TCP/IP) and reserve integrated interfaces will be more favored by system integrators and engineering projects.
2. Access to the fire protection system: ensure the smooth flow of emergency evacuation and escape routes
In the building fire protection linkage control, automatic doors also play an important role. Especially in public places such as office buildings, shopping malls, subways, and hospitals, the fire alarm linkage function of automatic doors directly affects the efficiency and safety of personnel evacuation.
Fire alarm signal priority control: When a fire alarm signal is received, the automatic door will automatically force open to form a barrier-free passage;
Power failure or forced unlocking mechanism: With fire priority logic, it automatically unlocks and opens the door after a power outage or manual trigger;
Unified programming control with the fire control system: Supports centralized scene deployment, which is convenient for unified response during fire drills or disaster emergencies.
For suppliers, whether the product passes the fire linkage test or related certification (such as CCCF) will directly affect its possibility of entering large public construction projects.
3. Access to security system: build a closed and controllable traffic environment
Automatic doors are integrated with security systems such as video surveillance, alarm equipment, and visitor management to improve the security level of entrances and exits:
Visitor linkage door opening: After the visitor makes an appointment or identity verification, the background system can remotely authorize the door opening and record the complete process;
Intrusion linkage alarm: When illegally prying the door or forcing passage, the alarm is automatically linked and the access control locking mechanism is activated;
Linked with video surveillance: The door opening behavior is bound to the on-site image and uploaded to the platform to achieve event traceability and risk control monitoring.
For integrators, whether the control system of the automatic door supports the ONVIF protocol, the security platform docking SDK or the open interface of the third-party system is an important indicator to examine whether it can adapt to the needs of intelligent security.
4. Summary of integration advantages: not only a "door", but also a "node"
In the intelligent building system, the role of the automatic door has long evolved from a single execution component to an intelligent gateway-level node that connects multiple systems and carries multiple functions. Its advantages are:
✅ Centralized control: all permissions, status, and alarms can be uniformly dispatched in the background
✅ System linkage: interconnected with access control, fire protection, security, and elevator systems
✅ Data closed loop: door movements can be traced back, recorded, and monitored
✅ Strong scene adaptation: support multi-building, multi-channel, and multi-type entrance and exit deployment
