receiving the first data, and performing identity verification on the intelligent lock;
after the legal identity of the intelligent lock is determined, a verification instruction is sent to the Internet of things terminal through the router;
receiving feedback data of the terminal of the Internet of things, and verifying and analyzing the feedback data;
and after the verification is finished, the control instruction is sent to the intelligent lock through the router.
It can be understood that, in order to improve security, the embodiment uses other terminals of the internet of things to perform identity authentication, so as to ensure that the smart lock is not invaded by a virus program or cracked. If a group can be formed by the intelligent lock and the Internet of things terminal, the remote server generates a secret key and a data splitting number for the group, and the intelligent lock and the Internet of things terminal split and encrypt data to be transmitted to the remote server according to the splitting number and disorder the data in the group. After receiving the data sent by the intelligent lock, the remote server firstly determines whether the data is a legal identity in a communication protocol, and when the data is determined to be the legal identity, the remote server acquires the data from the Internet of things terminal for further verification and analysis so as to determine that the request initiated by the intelligent lock is safe.
In some possible embodiments of the present invention, the router is integrated with an internet of things server (not shown in the figure), and the internet of things terminal is one or more; the smart lock is configured to:

the controller executes the temporary control instruction.
It can be understood that in real life, the network connection is disconnected frequently, which may cause communication abnormality between the intelligent lock and the remote server, so that the lock cannot be opened. In order to further improve user experience, a small-sized Internet of things server can be arranged in a router, a temporary control scheme (comprising a communication security level, an Internet of things terminal, an encryption protocol, a corresponding relation among the Internet of things terminal, the router and an intelligent lock, an intelligent lock control verification scheme and the like) which is preset by a remote server and synchronized to the Internet of things terminal, the router and the intelligent lock is utilized, after the intelligent lock determines the communication security level according to recorded historical data (such as physiological characteristic data of an unlocking person, unlocking behavior data of the unlocking person, unlocking time data, communication fault data and the like) and the human body image data, a first Internet of things terminal matched with the router and the intelligent lock is selected to form a temporary communication group according to the corresponding relation between the preset communication security level and the Internet of things terminal and the encryption protocol, the temporary communication group is communicated by utilizing the corresponding encryption protocol in the temporary communication group, the server arranged in the router completes verification of a temporary control request, and after the verification is passed, a temporary control instruction is sent to the intelligent lock; after the intelligent lock receives the temporary control instruction, the controller executes the temporary control instruction to complete the unlocking.

The vibration module is specifically a vibration sensor, and works by utilizing the piezoelectric effect of a piezoelectric material, a dielectric medium in the vibration module can generate mechanical deformation under the action of a certain external force to generate a polarization phenomenon, then positive charges can be generated on one surface of the dielectric medium, negative charges are generated on the other surface of the dielectric medium, after the external force is removed, the charges disappear to become an uncharged state, and therefore when a visitor knocks on the door, the vibration sensor is stressed to generate deformation due to knocking action, an electric signal is generated, a prompt signal is generated through processing of a controller, and the prompt module prompts the resident to visit. After a preset time (such as 1 minute) elapses, when the intelligent lock does not detect a response from a person, the intelligent lock sends an assistance instruction to an indoor internet of things terminal through an indoor router; the indoor Internet of things terminal determines whether indoor personnel exist in the room or not according to the assistance instruction, and if so, a prompt is sent to the indoor personnel; if not, the intelligent lock is fed back, and the reminding module prompts the intelligent lock.
In some possible embodiments of the invention, the intelligent lock may further obtain data from the internet of things terminal and/or the remote server, generate a prompt message, and send the prompt message to the reminding module, and the reminding module performs a reminding operation when a user goes out.
