Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
A method for keeping low power consumption of an intelligent lock comprises the intelligent lock, wherein the intelligent lock comprises a fingerprint module 1, the fingerprint module 1 comprises a fingerprint sensor 11, and the fingerprint module 1 is awakened in a manner that the fingerprint sensor 11 is triggered by a capacitor;
the method comprises the following steps:
step A: the fingerprint module 1 enters a fingerprint identification process after being awakened successfully;
and B: after the fingerprint identification process is carried out, if the fingerprint module 1 fails to enter the sleep mode, the fingerprint module 1 is forced to be powered down.
Because the fingerprint module 1 is awakened in a capacitive triggering mode of the fingerprint sensor 11, the fingerprint module 1 has certain application logic limitations (the capacitive triggering mode of the fingerprint sensor 11 specifically means that a capacitive touch chip is integrated on the fingerprint sensor 11 without additionally adding an external touch chip), and specifically, when the fingerprint module 1 is in a dormant state, if a finger touches the fingerprint sensor 11, the fingerprint module 1 is immediately awakened to perform fingerprint identification.
And, if want to touch the fingerprint sensor 11 next time, the fingerprint module 1 can awaken the work directly, before the fingerprint module 1 is awakened, the fingerprint module 1 must be in the sleep mode first.
Unblank under normal conditions, at first fingerprint module 1 is in the dormant state, and the user will point the touch to fingerprint sensor 11, fingerprint module 1 awakens up successfully, then carries out fingerprint identification, and the process of general fingerprint identification can be accomplished in the short time, and the fingerprint identification process can not exceed 1 second under the normal conditions, and after fingerprint identification succeeded, the intelligence lock was unblanked successfully, then fingerprint module 1 can normally enter into to the dormant mode, and at this moment, the user can follow the finger under the normal condition fingerprint sensor 11 takes away, fingerprint module 1 waits normally to be awaken up again and carries out fingerprint identification work of unblanking again.
But under extreme operation mode, when fingerprint module 1 awakens up and carries out fingerprint identification after succeeding in, user's finger is because long-time touch fingerprint sensor 11, when fingerprint identification succeeds in passing through the back, fingerprint module 1 can enter into sleep mode, nevertheless because user's finger still touches at fingerprint sensor 11, consequently, fingerprint module 1 just gets into sleep mode, can be awaken up immediately and enter into operating condition, and fingerprint module 1 is after verifying through fingerprint sensor 11 promptly, still gets into sleep state failure to lead to the electric quantity of intelligent lock to run off fast, greatly reduced the battery life of intelligent lock.
Therefore, the method of the present invention executes step A and then executes step B, namely, under the condition that the fingerprint module 1 fails to enter the sleep mode, the fingerprint module 1 is forced to be powered down, thereby effectively preventing the user from operating the intelligent lock under extreme conditions to cause the electric quantity of the intelligent lock to be rapidly lost and affecting the service life of the battery of the intelligent lock.
Therefore, the method can force the power down under the condition that the fingerprint module fails to enter the sleep mode, thereby ensuring that the intelligent lock is in a low power consumption state and ensuring the service life of the battery of the intelligent lock.
In one embodiment, after step a is performed, step B is specifically performed as follows:
whether the finger touches the fingerprint sensor 11 is detected firstly, if so, whether the time of the finger touching the fingerprint sensor 11 exceeds N seconds is judged, if so, the fingerprint module 11 is forced to be powered down under the condition that the fingerprint module 1 fails to enter the sleep mode.
Unblank under normal conditions, at first fingerprint module 1 is in the dormant state, and the user will point to touch to fingerprint sensor 11, fingerprint module 1 awakens up successfully, then carries out fingerprint identification.
When fingerprint module 1 awakens up and carries out fingerprint identification after succeeding in, no matter whether fingerprint identification succeeds or not, all will detect whether have the finger touch fingerprint sensor 11 surpass N second, if surpass N second, under the circumstances of fingerprint module 1 entering dormancy mode failure, fingerprint module 11 just can force the power down to can prevent effectively that the user from operating the electric quantity that intelligent lock made intelligent lock under extreme circumstances and losing fast.
The value of N may be preset by a user, where N in this embodiment is 10, that is, if the time exceeds 10 seconds, the fingerprint module 11 is forced to power down when the fingerprint module 1 fails to enter the sleep mode. Normally, the fingerprint is recognized, the whole process can be completed within 1 second, and the fingerprint recognition cannot exceed 10 seconds in most cases.
In one embodiment, after step a is performed, step B is performed, and the step B further comprises:
whether the finger touches the fingerprint sensor 11 is detected, if not, the fingerprint module 1 enters a sleep mode.
Unblank under normal conditions, at first fingerprint module 1 is in the dormant state, and the user will point to touch to fingerprint sensor 11, fingerprint module 1 awakens up successfully, then carries out fingerprint identification. When fingerprint module 1 awakens up and carries out fingerprint identification after succeeding in, no matter whether fingerprint identification succeeds or not, whether detect again has the finger touch fingerprint sensor 11, if not, then fingerprint module 1 gets into sleep mode, guarantees that fingerprint module 1 can be in the lower sleep mode of power consumption to also can guarantee the battery life of intelligent lock.
In one embodiment, the intelligent lock further comprises a keyboard 2;
further comprising the step C: any key of the keyboard 2 is touched, and the fingerprint module 1 enters a sleep mode.
Because fingerprint module 1 gets into sleep mode failure, fingerprint module 1 can force the power failure, after fingerprint module 1 forces the power failure, because fingerprint module 1 fails to get into sleep mode, the user touches fingerprint module 1 this moment and can not awaken up, can not carry out fingerprint identification work promptly.
Therefore, through setting the step C, any key of the keyboard 2 is touched, and the fingerprint module 1 enters the sleep mode, so that the fingerprint module 1 can still be wakened by touching the keyboard 2 under the condition that the touch wakening function is invalid, and the effective operation of the subsequent fingerprint identification work is ensured.
Further, in one embodiment, in step a, after the fingerprint identification is successful, step B is entered:
under the normal condition, after fingerprint identification succeeds, the intelligence lock is successfully unblanked, carries out step B immediately this moment, can judge effectively whether fingerprint module 1 can get into the sleep mode, if fingerprint module 1 can not get into the sleep mode, then fingerprint module 1 can force the power failure.
Further, in one embodiment, in step a, after the fingerprint identification fails, step B is entered:
although the fingerprint identification fails in this case, the smart lock cannot be normally unlocked; however, there is a possibility that even if the fingerprint recognition fails, the user will not move the finger away from the fingerprint sensor 11, so that the finger of the user is still placed in the fingerprint sensor 11 for a long time, and thus the fingerprint module 1 will still not normally enter the sleep mode because the finger of the user is placed in the fingerprint sensor 11 for a long time.
Therefore, even after fingerprint identification fails, still continue to carry out step B, finally make fingerprint module 1 forces to fall the power supply to guarantee fingerprint module 1 can still put the finger in fingerprint sensor 11 for a long time after fingerprint identification fails and can force to fall the power supply under the condition that fingerprint module 1 can not get into sleep mode, guarantee the life of intelligence lock battery.
The intelligent lock uses the method for keeping the low power consumption of the intelligent lock;
the system comprises a fingerprint module 1 and a power-down module 3;
the fingerprint module 1 comprises a fingerprint sensor 11;
the fingerprint sensor 11 performs fingerprint identification by adopting a self-contained capacitance triggering mode;
the power down module 3 is used for forcing the fingerprint module 1 to be powered down after the fingerprint module 1 fails to enter the sleep mode.
Because the awakening mode of the fingerprint module 1 adopts the triggering mode of the fingerprint sensor 11 with the capacitor, the fingerprint module 1 of this type has certain limitation in application logic, specifically, when the fingerprint module 1 is in a dormant state, if the fingerprint sensor 11 is touched by a finger, the fingerprint module 1 can be immediately awakened to carry out fingerprint identification work.
And, if want to touch the fingerprint sensor 11 next time, the fingerprint module 1 can awaken the work directly, before the fingerprint module 1 is awakened, the fingerprint module 1 must be in the sleep mode first.
Unblank under normal conditions, at first fingerprint module 1 is in the dormant state, and the user will point the touch to fingerprint sensor 11, fingerprint module 1 awakens up successfully, then carries out fingerprint identification, and the process of general fingerprint identification can be accomplished in the short time, and the fingerprint identification process can not exceed 1 second under the normal conditions, and after fingerprint identification succeeded, the intelligence lock was unblanked successfully, then fingerprint module 1 can normally enter into to the dormant mode, and at this moment, the user can follow the finger under the normal condition fingerprint sensor 11 takes away, fingerprint module 1 waits normally to be awaken up again and carries out fingerprint identification work of unblanking again.
But under extreme operation mode, when fingerprint module 1 awakens up and carries out fingerprint identification after succeeding in, user's finger is because long-time touch fingerprint sensor 11, when fingerprint identification succeeds in passing through the back, fingerprint module 1 can enter into sleep mode, nevertheless because user's finger still touches at fingerprint sensor 11, consequently, fingerprint module 1 just gets into sleep mode, can be awaken up immediately and enter into operating condition, and fingerprint module 1 is after verifying through fingerprint sensor 11 promptly, still gets into sleep state failure to lead to the electric quantity of intelligent lock to run off fast, greatly reduced the battery life of intelligent lock.
Therefore, the intelligent lock is provided with the power-down module 3, and the power-down module 3 is used for forcibly powering down the fingerprint module 1 after the fingerprint module 1 fails to enter the sleep mode.
Therefore, even if the finger of the user is placed on the fingerprint sensor 11 for a long time and causes the fingerprint module 1 cannot normally enter the sleep mode, the power failure module 3 can be used for forcing the fingerprint module 1 to fail, so that the service life of the battery of the intelligent lock is ensured.
Further, still include keyboard 2, arbitrary button of keyboard 2 enables fingerprint module 1 enters into sleep mode from the power down mode of forcing.
When fingerprint module 1 forces the power down after, because fingerprint module 1 fails to get into sleep mode, user's touch fingerprint module 1 can not be awaken up this moment, can not carry out fingerprint identification work promptly.
At this moment, any key of the keyboard 2 is touched, and the fingerprint module 1 enters the sleep mode from the forced power-down mode, so that the keyboard 2 can still be used for touch awakening under the condition that the touch awakening function of the fingerprint module 1 is invalid, and the effective operation of subsequent fingerprint identification work is ensured.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
