Preferably, the communication module may further include a bluetooth module 205.

The working principle of the present embodiment is described in detail in conjunction with two application scenarios of the present embodiment:

scene 1: the owner opens the door by swiping an authorized IC card.

When the owner enters the door, the card is placed on the card reading module 201, and the card reading module 201 obtains the card number and sends the card number to the control module 202; the control module 202 calls the storage module 203 to inquire the validity of the card number, if the card is a legal authorized card, the control module 201 outputs a control signal to the switching value signal output module 207, and the switching value signal output module 207 outputs a door opening signal to the external channel equipment to control the external channel equipment 3 to be opened. Meanwhile, the control module 201 controls the audio output module 207 to output a legal card alert sound, such as "door open, please close the door by hand". If the card is an illegal unauthorized card, the control module 201 triggers the audio output module 208 to output an illegal card alert tone, such as "the card is unregistered".

Scene 2: when a visitor arrives, the visitor informs the owner of the access requirement (adopting an off-system call mode), and the owner remotely opens the door through a mobile phone.

The owner needs to obtain system authorization (for example, door opening authority is obtained through mobile phone APP registration and applet registration), the visitor can contact the owner through telephone, social software and other modes to inform the owner of own access requirements, and the owner can remotely control the door opening through the mobile phone after knowing visitor information. Specifically, the owner mobile phone terminal 1 (in the form of mobile phone terminal software) is connected to the network communication module 204, and sends a door opening request to the control module 202 through the network communication module 204, the control module 202 notifies the switching value signal output module 207 to output a door opening signal, controls the external channel device 3 to be opened, and meanwhile, the audio output module 208 outputs a prompt tone.

Example 2

Example 3

On the basis of the embodiment 2, the visitor mobile phone terminal 4 and the owner mobile phone terminal 1 are in communication connection in a mobile phone software manner, so that the owner can provide the door opening authority for the visitor. An application scenario of the present embodiment is provided below:

scene 4: the visitor makes an access request to the owner, and the visitor authorized by the owner opens the door autonomously.

On the basis of scenario 3, the visitor of this embodiment has an autonomous door opening right, but the right needs to be provided by the owner. When a visitor puts forward an access request to a home owner, the visitor can select any call mode (mobile phone, social software, SIP call and the like) of

scenes

2 and 3 to request the home owner for the door opening permission, and also can send a reservation application to the home owner through mobile phone terminal software, at the moment, the home owner mobile phone terminal software is additionally provided with a visitor reservation function, the visitor mobile phone terminal software is additionally provided with an access reservation function, and the home owner can approve the reservation request of the visitor. In this scenario, no matter how the visitor notifies the owner of his own access request, the final door opening authority is implemented by the mobile phone software of the visitor.
