That is, the intelligence lock can set up multiple identification module simultaneously, increases the function of intelligence lock, has improved user's experience. Therefore, the present application is not limited to the specific structure of the intelligent door lock.
Referring to fig. 3, an unlocking method is provided in the present embodiment, and is applied to the intelligent door lock in the above embodiments. The method comprises the following steps: step S101-step S104.
Step S101: and receiving voice information of a user.
Step S102: and comparing the voice information with the first preset voice and the second preset voice.
Step S103: and judging whether the voice information is successfully compared with the first preset voice and the second preset voice.
Step S104: and if the voice information is successfully compared with the first preset voice and the second preset voice, the switch is controlled to be turned on.
According to the unlocking method provided by the embodiment of the application, when voiceprint recognition is carried out, verification is carried out through two sections of voice, and a section of normal unlocking password and an additional password are required. The second preset voice is one of the pre-recorded multiple sections of voices, and the user can set the second preset voice adopted when unlocking every time according to requirements. Thus, a number of different unlocking codes can be combined, but only one of them is correct. Compared with the prior art, the voice synthesis difficulty is also improved through the mode under the condition that the door is opened through the recording after the recording of a person is effectively avoided, and the safety of the intelligent door lock is further improved.
The above steps are described below with reference to specific examples.
Step S101: and receiving voice information of a user.
The smart door lock receives voice information of a user, and specifically, the microphone of the voiceprint recognition module 20 is used for receiving voice information of the user. And after the microphone receives the voice information sent by the user, the voice information is sent to the voiceprint chip. In this embodiment, the voice message of the user needs to include an unlock password and an additional password.
Step S102: and comparing the voice information with the first preset voice and the second preset voice.
During voiceprint comparison, firstly, feature extraction is carried out on the voice information, and then the voice information after feature extraction is compared with the first preset voice and the second preset voice.
The unlocking password corresponds to a first preset voice, and the additional password corresponds to a second preset voice. The first preset voice and the second preset voice are both voices which are pre-recorded in the intelligent door lock. For example, the first preset voice may be "i'm's back", "please open the door", "sesame open the door", or the like. The user needs to say the unlocking password corresponding to the first preset voice at the time of voiceprint authentication. Assuming that the set first preset voice is 'sesame open door', the unlocking password that the user needs to say is 'sesame open door'. The second preset voice is one of the voices recorded in the intelligent door lock in advance. For example, the pre-recorded voice may be "clear up river map", and the second preset voice may be any one of "clear", "up", "river" and "map". Of course, any one of the words "Qingming", "Shanghe" and "figure" may be used. Of course, the second preset voice may also be a plurality of voices, for example, the pre-recorded voice is "clear going to the river," the "speed is not reached," and the "day is taken as food," and the second preset voice may be any one of the words "clear going to the river," the "speed is not reached," and the "day is taken as food. Assuming that the second voice set is "river", the additional password that the user needs to say is "river".
Optionally, the second preset voice may be determined sequentially according to a voice recording sequence in the voices recorded in advance in the intelligent door lock. The description is given by taking "clear upper river map" as an example, for example, the second preset voice is any one of "clear", "up", "river" and "map". When the user sets, the second preset voice appearing each time can be determined according to the character sequence of 'clear river at the upper river level'. For example, the second preset voice is changed every 24 hours, that is, the second preset voice needs to be determined every 24 hours. On the first day, the second preset voice is clear, and then the user will clearly know that the second preset voice on the second day is clear, and correspondingly, the second preset voice on the third day is up. Of course, in other embodiments, the second preset voice may be changed every 12 hours, or every 48 hours.
Step S103: and judging whether the voice information is successfully compared with the first preset voice and the second preset voice.
As a way of determining whether the comparison is successful, the step S103 may include: and judging whether the comparison result of the voice information and the first preset voice is greater than a first threshold value or not, and judging whether the comparison result of the voice information and the second preset voice is greater than a second threshold value or not.
The steps are that a section of complete voice information of a user is compared with a first preset voice and a second preset voice respectively. The voice information of the user comprises an unlocking password and an additional password, the unlocking password corresponds to first preset voice, and the additional password corresponds to second preset voice. The first threshold and the second threshold may be set according to the lengths of the first preset voice and the second preset voice, for example, the first preset voice and the second preset voice are both two words. The first threshold and the second threshold may be both 45%, that is, the comparison is successful only when the comparison result between the voice information of the user and the first preset voice is greater than 45% and the comparison result between the voice information of the user and the second preset voice is also greater than 45%. For another example, if the first preset speech is 5 words and the second preset speech is 1 word, the first threshold may be 70% and the second threshold may be 15%. Correspondingly, the comparison is successful only when the comparison result of the voice information of the user and the first preset voice is more than 70% and the comparison result of the voice information of the user and the second preset voice is more than 15%. The specific values of the threshold are not limited in this application.
As a way of determining whether the comparison is successful, the step S103 may include: combining the first preset voice and the second preset voice to obtain combined voice; and judging whether the comparison result of the voice information and the combined voice is greater than a third threshold value.
The step is to compare a section of complete voice information of the user with a combined voice obtained by adding the first preset voice and the second preset voice. For example, the third threshold may be set to 80%, and when the comparison result of the combined voice obtained by adding the voice information of the user and the first preset voice and the second preset voice is 80%, the comparison is successful. The third threshold may also be set to 90%, 85%, etc., and the application is not limited thereto.
Step S104: and if the voice information is successfully compared with the first preset voice and the second preset voice, the switch is controlled to be turned on.
If the comparison is successful, the unlocking password and the additional password of the user are correct, and the control switch is turned on at the moment.
Correspondingly, if the comparison between the voice information and the first preset voice and the second preset voice fails, the switch is controlled to be continuously closed.
Optionally, the intelligent door lock provided in the embodiment of the present application may further include an alarm module. And after the user fails to compare for a certain number of times, triggering an alarm module to give an alarm. For example, after the comparison of the user fails five times, the alarm module is triggered to alarm.
The embodiment of the application also provides an unlocking method for prompting through the display screen. This mode needs to be provided with the display screen that can be used to show the characters on intelligent lock.
Specifically, before step S101, the method further includes: and displaying the prompt words of the second preset voice.
The prompt word is used for prompting the keyword in the second preset voice to the user.
For example, the pre-recorded voice may be "clear up river map", and the second preset voice may be any one of "clear", "up", "river" and "map". However, in order to avoid the user forgetting which word the code is attached to, the prompt may be made through the display. For example, when the second preset voice may be "clear", the cue may be "inter-person is tasty and clear"; when the 'taste among people is clear' appears on the display screen, the user knows that the additional code is the 'clear' word. Accordingly, when the second preset voice may be "bright", the cue may be "light before bed". Accordingly, when the second preset voice may be "up", the cue may be "the water of the yellow river comes up". Accordingly, when the second preset voice may be "river", the cue word may be "country breaking mountain river at. Accordingly, when the second predetermined voice may be "nation", the cue may be "new makeup competing with drawing". It is understood that the cue word may also be a phrase containing a keyword, and of course, the cue word may also be the keyword itself, for example, when the second preset speech may be "up", the cue word may be the word "up". Before the intelligent door lock is used, a prompt word corresponding to each keyword of the second preset voice needs to be imported into the intelligent door lock.
In the embodiment of the application, the display screen is arranged on the intelligent door lock, the prompt words with the second preset voice can be displayed, and the user is prevented from forgetting the additional password.
Optionally, the display screen can be used for prompting the user for the keywords in the second preset voice. Therefore, the second preset voice may be randomly determined among the voices previously entered in the smart door lock. Through the mode, the password combined each time has uncertainty, and other people can hardly guess the pre-recorded voice as 'clear river map', so that the safety of the intelligent door lock is further improved.
Optionally, after the comparing the voice information with the first preset voice and the second preset voice, the method further includes: and updating the second preset voice according to the recording sequence of the voice.
That is, after the user uses the additional password each time, the second preset password is used as a basis. For example, when the current second preset voice is "clear", the user speaks voice information to verify when opening the door, and the second preset password is updated once no matter whether the verification is correct or not. The second preset voice becomes "bright" the next time the user opens the door. Through the mode, the problem that other people try to unlock the prompt words on the display screen one by one can be avoided.
Of course, in other embodiments, after the comparing the voice information with the first preset voice and the second preset voice, the method further includes: and randomly updating the second preset voice according to the recorded voice.
In summary, the unlocking method for prompting through the display screen provided by the embodiment of the application can display the prompt words of the second preset voice, and avoids the situation that a user forgets to attach a password.
Referring to fig. 4, based on the same inventive concept, the embodiment of the present application further provides another unlocking method, which is applied to the intelligent door lock in the above embodiment. The method comprises the following steps: step S201-step S208.
Step S201: first voice information of a user is received.
Step S202: and comparing the first voice information with a first preset voice.
Step S203: and judging whether the comparison result of the first voice information and the first preset voice is greater than a fourth threshold value.
Step S204: if the comparison result of the first voice information and the first preset voice is larger than the fourth threshold, sending a prompt instruction to the user; and the prompt instruction is used for prompting the user to perform the second verification.
Step S205: and receiving second voice information of the user.
Step S206: and comparing the second voice information with a second preset voice.
Step S207: and judging whether the comparison result of the second voice information and the second preset voice is greater than a fifth threshold value.
Step S208: and if the comparison result of the second voice information and the second preset voice is greater than a fifth threshold value, controlling the switch to be turned on.
It should be noted that, the difference between the unlocking method provided in the above steps S201 to S208 and the unlocking method provided in the steps S101 to S104 is that the two voice verification processes of the unlocking method provided in the steps S201 to S208 are in a sequential order. The first voice information corresponds to an unlocking password, and the second voice corresponds to an additional password. That is, the user needs to verify the unlocking password first, and only after the unlocking password passes the verification, the verification of the additional password is carried out. Therefore, other similar steps may be referred to each other, and in order to avoid redundancy, a repeated explanation is not provided herein.
In the step S204, if the comparison result of the first voice message and the first preset voice is greater than the fourth threshold, a prompt instruction is sent to the user, where the prompt instruction may be that after the comparison result of the first voice message and the first preset voice is greater than the fourth threshold, a prompt word of a second preset voice is displayed on the display screen. When the prompt words of the second preset voice are displayed on the display screen, the unlocking password verification is successful. And when the prompt words of the second preset voice are not displayed on the display screen, the unlocking password authentication failure is explained. Of course, the smart door lock may further include a speaker, and a prompt instruction may also be sent to the user through the speaker, such as playing a voice through the speaker, "please speak an additional password," or "please continue to perform verification," or the like. The present application is not limited thereto.
In summary, in the embodiment of the present application, during voiceprint recognition, two sections of voice verification are required, and a section of normal unlocking password and an additional password are required. The user needs to verify the first unlocking password, and the additional password can be verified only after the unlocking password passes verification. The safety of the intelligent door lock is improved through two times of verification.
Based on the same invention concept, the embodiment of the application also provides an unlocking device which is applied to an intelligent door lock, wherein the intelligent door lock comprises a voiceprint recognition module, a switch and a controller; the controller respectively with voiceprint recognition module and the switch electricity is connected, the device includes: the device comprises a first receiving module, a first comparison module, a first judgment module and a first control module.

And the first control module is used for controlling the switch to be switched on if the voice information is successfully compared with the first preset voice and the second preset voice.
Optionally, when the intelligent door lock comprises a display screen, the device further comprises a display module, and the display module is used for displaying the prompt word of the second preset voice before receiving the voice message of the user; and the prompt words are used for prompting the keywords in the second preset voice to the user.
