In the process of unlocking information transmission, in order to prevent the unlocking information from being interfered or collided, the unlocking information is coded in the embodiment, and the unlocking information is coded into digital information more suitable for transmission, namely coded information.
And step S2, the user equipment decodes the primary coding information to obtain decoding information.
And step S3, the user equipment carries out secondary coding on the decoding information to obtain secondary coding information.
In steps S2 and S3, the ue decodes the primary encoded information using the repeater and then performs secondary encoding, thereby extending the data transmission distance for subsequent improvement of data transmission efficiency.
And step S4, the user equipment encrypts the secondary coding information to generate target information and sends the target information to a server.
Specifically, the user equipment encrypts the coded information, so that the information on the communication line is effectively prevented from being leaked, and the integrity of the coded information is verified, so that the security of unlocking information transmission is improved.
Step S5, the server acquires the target information, decodes the target information, and verifies the decoded target information.
After receiving the target information, the server needs to decode the encoded target information and convert the signal form of the target information in order to quickly verify the unlocking information, wherein the decoding method corresponds to the encoding method.
And step S6, if the verification is passed, the server generates a dynamic password based on a preset dynamic password rule and sends the dynamic password to the intelligent lock.
The dynamic password is a random code automatically generated by the server. And after the target information passes the verification, the server automatically generates a dynamic password according to a prestored dynamic password rule and sends the dynamic password to an intelligent lock which is communicated with the server through a preset wireless private network.
And step S7, the intelligent lock generates a standard dynamic password based on a pre-stored dynamic password rule, and when the dynamic password is consistent with the standard dynamic password, the intelligent lock executes an unlocking action.

For example, taking an example that the user equipment sends the login request to the server in a communication manner, the user equipment encrypts the login request by using an AES encryption manner and a public key, and then encrypts the connection channel by using an SSL encryption manner. After receiving the login request, the server firstly decrypts by using an SSL decryption mode, and then encrypts by using an AES decryption mode together with a public key, so as to obtain the login request.
