With the continuous iteration of technology, the face access control recognition system continues to evolve with technology and demand, showing the characteristics of high integration, high security, high intelligence, and multiple door opening methods. The appearance, function, technology, etc. have undergone qualitative changes, but the three major modules have not changed, namely the perception module, the control module, and the execution module.

The control module is the key core of the whole system, and the core of the control unit is the controller, which mainly plays the role of data processing and storage. It is a key part of access control and is mainly responsible for the transmission of the second read head. The process of decoding and confirming information such as dimension codes and swiping cards.

What are the specific functions of the controller? It is usually embodied in the linkage of turnstiles, firefighting, and elevators. The controller performs corresponding authority work and processes different signals.

When the controller controls the gate, we mainly control the switch signal of the gate through the controller. Once someone swipes the door control through the entrance, the system will identify whether the door is authorized to pass according to the personnel's authority. After passing the access control system, the gate will accept the transmission. The control signal automatically opens the gate switch to allow personnel to enter.

When the controller is linked with the fire protection module, in the event of a fire, you only need to send a dry contact signal to the access controller, and the access controller will automatically open all doors. At the same time, the equipment is also equipped with a fire button to cancel.

When the access control controller is linked with the elevator control module, as long as the personnel pass the access control, the signal is transmitted to the elevator control system through the controller, and the system will automatically call and dispatch according to the permissions set by the user Elevator personnel.

The controller is mainly composed of main control module, input/output module, multi-door module, network module, sound and light module. The input and output module is responsible for signal transmission and supports multi-channel signal transmission. The multi-door module is mainly responsible for controlling all kinds of electronic door locks, and at the same time responsible for the fire protection linkage, communicating with the reading head, and receiving the signals transmitted by the reading head. The network module connects the access control system to the network, and integrates the access control system of different scenes through the server for unified and efficient management.

The security module mainly guarantees the security of access control. It is connected to the main control through RS485, and realizes the door lock control relay, door opening button detection, and fire button detection on it. Separate the door opening execution unit from the front-end user operation unit to reduce the possibility of opening the door after the door is damaged.
