Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a flowchart of an embodiment of an optical communication-based unlocking method according to the present invention. As shown in Fig. 1, the method includes:

If it is determined that the electronic key is compatible with the electronic lock, the optical signal corresponding to any key in the preset key pool is sent to the electronic key as a pre-unlocking signal.

receiving an unlocking signal sent by the electronic key according to the pre-unlocking signal, matching the unlocking signal with the pre-unlocking signal, and performing an unlocking operation if the matching is successful.

Wherein, the electronic key and the electronic lock share the preset key pool, the preset key pool is a key set including a plurality of keys, and the unlocking signal is obtained from the electronic key by the The optical signal corresponding to the key selected in the preset key pool.

In the embodiment of the present invention, the concept of "optical lock" is introduced. The optical lock is a combination lock based on wireless optical communication, which includes two parts: an electronic key and an electronic key. For a set of optical locks, the electronic key and electronic lock are compatible, and the two-way communication is realized based on the principle of wireless optical communication.

For a set of optical locks, the electronic key and the electronic lock share a key pool. Among them, "share a key pool" means: when the electronic key and the electronic lock exchange light signals, they are based on the key The keys in the pool are used to send optical signals. For example, when the electronic lock sends an optical signal to the electronic key, it first needs to select a key from the key pool, and then send the optical signal corresponding to the key to the electronic key. Because this key pool is preset, it can also be called a preset key pool. Wherein, the preset key pool includes multiple keys. The key is a specific signal sequence, and its composition includes start and stop flag bits and data bits, and the data bits can be changed as needed. It should be noted that the preset key pool may only be located in the cloud, and both the electronic lock and the supporting electronic keys share the key pool. It can be understood that the preset key pool can also be located in the electronic lock and the electronic key at the same time.

The unlocking method provided by the embodiment of the present invention is executed by an electronic lock. First of all, the electronic lock needs to determine whether the electronic key held by the user is compatible with the electronic lock. If it is compatible, the electronic lock will randomly extract a key from the preset key pool, and the optical signal corresponding to the key It is sent to the electronic key as a pre-unlock signal. It should be noted that the optical signals corresponding to different keys are different.

When the electronic key receives the pre-unlock signal sent by the electronic lock, the user holding the electronic key can select a key from the preset key pool according to the pre-unlock signal and send it to the electronic lock as an unlock signal.

When the electronic lock receives the unlocking signal sent by the electronic key, it matches the unlocking signal with the pre-unlocking signal, and if the matching is successful, the electronic lock executes the unlocking operation.

It can be known that if the user holding the electronic key is the owner of the optical lock, the key selected by the owner from the preset key pool must be correct. Pre-unlock signal match. If the user holding the electronic key is a criminal, the probability of the criminal selecting the correct key from the preset key pool is extremely low, in other words, the probability of unlocking is extremely low.

In the unlocking method provided by the embodiment of the present invention, after "pressing" the key, the lock will judge the signal sent by the key. If the key matches the lock, the lock will send a pre-unlock signal to the key, and the key will receive the pre-unlock signal. The unlock signal will be sent to the lock after the signal, and then the lock will verify whether the unlock signal matches the pre-unlock signal, and finally the lock decides whether to unlock. The unlocking method provided by the embodiment of the present invention can effectively prevent criminals from unlocking after the key is lost or stolen, and at the same time makes up for the defects that the scope of application of smart locks such as fingerprint recognition locks and face recognition locks is limited to individuals and is easily disturbed by external conditions. The beneficial effects of convenient use and high safety are achieved.

Based on the above embodiments, this embodiment describes how to determine whether the electronic key is compatible with the electronic lock. It is determined that the electronic key is compatible with the electronic lock, which also includes:

A trigger signal sent by the electronic key is received, and if the key corresponding to the trigger signal is any key in the preset key pool, it is determined that the electronic key is compatible with the electronic lock. Otherwise, it is determined that the electronic key is not compatible with the electronic lock.

Specifically, the electronic lock receives a trigger signal sent by the electronic key, and if the key corresponding to the trigger signal is a certain key in the preset key pool of the electronic lock, the electronic lock determines that the electronic key is compatible with the electronic lock. It should be noted that the trigger signal is an optical signal corresponding to a key randomly drawn by the electronic key from its own preset key pool.

It can be understood that, for a set of optical locks, its electronic key shares a preset key pool with the electronic lock, then, the key randomly extracted by the electronic key from the preset key pool must satisfy the "trigger The signal is any key in the preset key pool", therefore, the electronic key must be compatible with the electronic lock.

The unlocking method provided in this embodiment is different from the unlocking method of a common combination lock. Ordinary combination locks will check directly after receiving the signal from the key, and if they are equal, the lock will be unlocked. The unlocking method provided in this embodiment, after receiving the signal 1 (trigger signal) sent by the key, if the trigger signal is correct, it will extract from the key pool and send a signal 2 to the key. It should be noted that the signal 1 There is no necessary connection with signal 2. After the key receives signal 2, the user needs to judge what signal the key should send to the lock. When the user uses the key to send a signal 3 to the lock, the lock will judge whether the signal 3 is the same as that sent by the lock according to the key rules after receiving signal 3. Signal 2 matches.

In other words, after the key receives the pre-unlock signal, the user needs to judge what signal should be sent to the lock. If it is the owner, it will know what kind of signal the lock is opened according to the pre-unlock signal, and it will send an unlock signal to the lock. After the lock receives the signal sent by the key again, if this signal is the same as the unlocking signal specified before the lock, the lock will be opened.

Based on the above embodiment, if the matching fails, send the optical signal corresponding to any key in the preset key pool as a pre-unlock signal to the electronic key again, and receive the unlock signal sent by the electronic key , and match the unlock signal with the pre-unlock signal; if the number of consecutive matching failures exceeds the preset alarm times threshold, an alarm operation is performed.

Specifically, if the first match fails, the electronic lock will randomly extract a key from the preset key pool as a pre-unlock signal and send it to the electronic key, and the electronic key will send the unlock signal again according to the operation of the electronic key holder. Give the electronic lock. The electronic lock matches the unlocking signal with the pre-unlocking signal, and if the matching fails, the above process is repeated again. If the number of consecutive matching failures exceeds the preset alarm threshold, the electronic lock will perform an alarm operation.

The unlocking method provided by the embodiment of the present invention improves the security of the optical lock by recording the number of consecutive unlocking failures and performing an alarm when the number exceeds a threshold.

Based on the above embodiments, the keys in this embodiment are preferably binary sequences with the same structure. Each binary sequence includes start and stop flag bits and data bits. And the decimal numbers corresponding to all binary sequences are different. Correspondingly, matching the unlocking signal with the pre-unlocking signal also includes: numbering all the keys in the preset key pool, and the numbers corresponding to different keys are different.

Matching the unlock signal with the pre-unlock signal further includes:

If the pre-unlock signal corresponding to the key numbered X _i and the unlock signal corresponding to the key numbered X _j meet the following conditions:

Wherein, Z is the number of all keys in the preset key pool,

Then the unlocking signal matches the pre-unlocking signal successfully; otherwise, the matching fails.

Specifically, as a preferred embodiment, assuming that there are Z keys in the key pool, for the convenience of description, let Z=2n+1, n is a non-zero positive integer, and the keys are encoded in binary and can be compared with decimal convert. Assume that the numbers of the 2n+1 signal sequences are respectively X ₁ , X ₂ , X ₃ , . . . , X _2n+1 . The values indicated by _{X 1} , X ₂ , X ₃ , . For example, when it is determined that the electronic key is compatible with the electronic lock, the electronic lock will extract a key numbered Xi from the _preset key pool as a pre-unlock signal and send it to the electronic key, and the electronic key will correspond to the pre-unlock signal The binary sequence is converted into a decimal value and displayed to the user. According to the decimal value, the user extracts a key from the preset key pool and sends the key to the electronic lock as an unlock signal. Only when the number of the key corresponding to the unlocking signal is _Xj , the electronic lock performs the unlocking operation. It should be noted that the subscripts i and j need to meet the following conditions: when i≤n+1, j=i+n and when i>n+1, j=in-1, only then can the unlocking signal and pre-locking signal be explained. The unlock signal matches. It should be noted that only the owner of the key knows the above matching verification method.
