All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "comprising" and "having," and any variations thereof, as appearing in the specification, claims and drawings of this application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. In addition, the terms "first", "second", and "third", etc. are used to distinguish different objects, and are not used to describe a particular order.

Referring to fig. 1, fig. 1 is a system architecture diagram of a method for detecting a mechanical lock stroke according to an embodiment of the present invention, where the system architecture diagram includes a lock body 10 and a panel 20.

In the present embodiment, the faceplate 20 is mounted outside the lock hole of the lock body 10. The panel 20 includes a motor 201, a plurality of gears 202, and an encoder 203. Wherein, motor 201 drives a plurality of gears 202, and a plurality of gears 202 drive the key shrink to drive encoder 203 and encode, encoder 203 obtains the code value.

The mechanical lock body formed by the lock body 10 and the panel 20 installed outside the lock hole of the lock body 10 includes, but is not limited to, a fingerprint identification smart mechanical lock and a password input smart mechanical lock.

In this embodiment, first, the motor 201 drives the plurality of gears 202 to drive the key to move, the key moves in a first direction, and the plurality of gears 202 drive the encoder 203 to encode, so as to obtain a first encoded value. Wherein the first direction is any direction. Then, the motor 201 drives the plurality of gears 202 to drive the key to move again, the key moves to the second direction, and the plurality of gears 202 drive the encoder 203 to encode, so as to obtain a second encoded value, wherein the first direction is opposite to the second direction. And finally, after the code values of the mechanical lock bodies in the two directions are obtained, calculating the absolute value of the difference value between the first code value and the second code value. The absolute value is a calibration stroke of the mechanical lock body, wherein the calibration stroke is a stroke from locking and locking to unlocking and locking of the key.

Referring to fig. 2, fig. 2 is a diagram illustrating a specific application scenario of a method for detecting a stroke of a mechanical lock according to an embodiment of the present application, where the scenario is that a user obtains a calibration stroke of the mechanical lock.

The specific scenes are as follows:

first, the user clicks the lock first calibration button on APP. Then, the motor drives a plurality of gears to rotate to any direction and can not rotate any more, namely, the first locked rotor. At this time, the key also moves to the extreme value in any direction. In the mechanical lock body, the motor drives a plurality of gears to rotate to the locked rotor in the first direction at the same time, and drives the key of the mechanical lock body to move and the encoder to encode to obtain a first encoding value.

Then, the motor drives the gears to rotate in the opposite direction of the arbitrary direction until the gears cannot rotate, namely, the gears are locked to rotate for the second time, and a second code value is obtained.

And finally, calculating the absolute value of the difference value between the first coding value and the second coding value to obtain the calibration stroke of the mechanical lock body, wherein the calibration stroke is the whole stroke of the key of the mechanical lock body, namely the stroke from one locked-rotor position of the key of the mechanical lock body to the locked-rotor position in the opposite direction.

Referring to fig. 3, fig. 3 is a schematic flowchart of a method for detecting a stroke of a mechanical lock according to an embodiment of the present application, where the method is applied to an apparatus for detecting a stroke of a mechanical lock, as shown in fig. 3, and includes steps 301 to 303:

301: a plurality of gear rotation mechanical lock bodies are driven through the motor, the mechanical lock bodies rotate to the locked rotor in the first direction, and the encoder is driven to encode to obtain a first encoding value.

In this embodiment, the mechanical lock body composed of the lock body and the panel is different from the conventional mechanical lock, and the mechanical lock body composed of the lock body and the panel can be opened not only by a key but also by a fingerprint or a password. When a user uses a mechanical lock body consisting of a lock body and a panel for the first time, the mechanical lock body does not carry out stroke calibration, so that the mechanical lock body cannot be opened when the user uses fingerprints or passwords to unlock the lock. Thus, a user is required to perform a trip calibration at the time of first use.

Referring to fig. 4, fig. 4 is a schematic diagram of a first calibration provided in the embodiment of the present application. The user can install corresponding APP in the mobile device first, and can also directly carry out calibration on the panel. The present embodiment will be described by taking an example in which a user installs a corresponding APP.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a first calibration in a first direction according to an embodiment of the present disclosure. The user first clicks the lock first calibration button on the APP. Then, a motor in the panel drives a plurality of gears to rotate; when the gears rotate, the keys in the lock body are driven to move towards a first direction; simultaneously, a plurality of gears also drive the encoder of connecting and encode. When the key can not move to the first direction any more, it means that the lock body has reached the first locked rotation, i.e. the end point of the first direction rotation. At this time, the encoder encodes the first encoded value obtained for subsequent calculation.

Wherein, drive the encoder and encode, obtain first code value, include:

first, please refer to fig. 6, where fig. 6 is a schematic diagram of an initial electrical signal according to an embodiment of the present disclosure. When the encoder is used for encoding, two paths of orthogonal pulses of A and B, namely an A-phase pulse and a B-phase pulse, are emitted, and the phase difference between the A-phase pulse and the B-phase pulse is 90. And acquiring an initial electric signal diagram of the encoder and an initial encoding value thereof when the mechanical lock body calibration is not carried out. Referring to fig. 7, fig. 7 is a schematic diagram of a first electrical signal of an encoder when a mechanical lock body starts to be calibrated and the mechanical lock body rotates from a first direction to a locked state, as shown in fig. 7, which includes an initial electrical signal diagram.

Then, the variation value of the encoder can be obtained according to the variation of the A-phase pulse and the B-phase pulse of the first electric signal diagram and the initial electric signal diagram. Referring to fig. 6 and 7, it can be seen that in the initial electrical signal diagram and the first electrical signal diagram, the upper and lower a-phase pulses and the B-phase pulses are changed. Wherein, a high level and a low level in the a-phase pulse are one pulse, and a high level and a low level in the B-phase pulse are also one pulse. Thus, a four pulse variation number can be obtained from fig. 7. Moreover, the change of one pulse also represents the change of the coding value of one encoder, so that the change value of the coding value of the encoder in the first stalling process can also be obtained to be 4.

Then, acquiring a pulse edge increment value in the first electric signal diagram and a pulse edge increment value of the initial electric signal diagram, and determining the direction of the pulse edge increment value in the first electric signal diagram according to the pulse edge increment value in the first electric signal diagram and the pulse edge increment value of the initial electric signal diagram, wherein the pulse edge increment value is determined by the change of an A-phase pulse and a B-phase pulse in the first electric signal diagram; if the pulse edge increment value in the first electric signal diagram and the pulse edge increment value in the initial electric signal diagram have the same sign, the direction is unchanged; if the pulse edge increment value in the first electric signal diagram and the pulse edge increment value in the initial electric signal diagram have opposite signs, the directions are opposite.

Referring to fig. 7, the increment value of the edge of the pulse is obtained when the pulse of the a phase and the pulse of the B phase change.

As shown in fig. 7, when the level state of the a-phase pulse is a rising edge and the level state of the B-phase pulse is held constant, the pulse edge increment value is determined to be 1; when the level state of the A-phase pulse is a falling edge and the level state of the B-phase pulse is kept unchanged, determining that the increment value of the pulse edge is-1; when the level state of the A-phase pulse is kept unchanged and the level state of the B-phase pulse is a rising edge, determining that the increment value of the pulse edge is 1; when the level state of the A-phase pulse is kept unchanged and the level state of the B-phase pulse is a falling edge, the pulse edge increment value is determined to be-1.

Therefore, the pulse edge increment value in the first electric signal diagram and the pulse edge increment value of the initial electric signal diagram can be obtained, and the direction of the pulse edge increment value in the first electric signal diagram is determined. Referring to fig. 7, if the pulse edge increment value in the initial electrical signal diagram is 4, and the pulse edge increment value in the first electrical signal diagram is 0, the directions of the initial electrical signal diagram and the first electrical signal diagram are the same, i.e. the encoding value is increased by 4.

And finally, obtaining a first coding value according to the initial coding value and the change value of the coder.

302: the motor drives the plurality of gears to rotate the mechanical lock body, the mechanical lock body rotates to the locked rotor in the second direction, and the encoder is driven to encode to obtain a second encoded value, wherein the first direction is opposite to the second direction.

In this embodiment, please refer to fig. 8, and fig. 8 is a schematic diagram illustrating a first calibration in a second direction according to an embodiment of the present disclosure. When the motor can not drive the gears to drive the key to move towards the first direction, the motor drives the gears to drive the key to move towards the opposite direction of the first direction, namely, the second direction. Meanwhile, the plurality of gears drive the encoder to encode. And until the motor can not drive the gears to further drive the key to move towards the second direction, namely the second locked rotor, and a second coding value in the coder is obtained.

303: and calculating the absolute value of the difference value between the first code value and the second code value to obtain the calibration stroke of the mechanical lock body, wherein the calibration stroke is the stroke of the mechanical lock body from locking to unlocking.

In this embodiment, when the first coded value is corresponding to the mechanical lock body rotating in the first direction until the mechanical lock body cannot rotate any more, the first coded value at this time is the first direction rotation blocking value. The second code value corresponds to a second code value of the mechanical lock body, and the second code value is locked in a second direction by the first code value locked in a first direction. The calibration stroke direction of the whole stroke mechanical lock body of the first code value locked in the first direction and the second code value locked in the second direction is opposite. Therefore, the calibration stroke of the mechanical lock body is the absolute value of the difference value between the second code value and the first code value. The mechanical lock body calibration stroke can be obtained through two times of locked rotor detection in opposite directions, so that a user can calibrate as soon as possible to use the mechanical lock body.

In this embodiment, in order to obtain the operating state of the mechanical lock at the time of the first direction lock rotation or the second direction lock rotation, the user uploads the unlocked state or the locked state at the time of the lock rotation to the mechanical lock at the time of calibration.

Please refer to fig. 9, fig. 9 is a schematic diagram of determining a locked rotor state according to an embodiment of the present disclosure. For example, when the mechanical lock body reaches the locking locked rotation, the user confirms that the working state of the mechanical lock body is the locking state at this time in the APP based on whether the mechanical lock body is seen to be open or closed. Then, when the mechanical lock body reaches the unlocking locked rotor, the working state of the mechanical lock body is the unlocking state.

In another embodiment, the mechanical lock body can be a fingerprint intelligent identification lock or a password intelligent identification lock. The mechanical lock body needs to be energized in order to be usable. However, when the mechanical lock body is powered off due to an unstable factor, a user may unlock or lock the mechanical lock body by using a key or a knob on the mechanical lock body. At this time, if the mechanical lock body is powered on again, the mechanical lock body cannot determine the calibration stroke. Because of the manual unblanking or the lock of closing of user, unblanking or close the lock at every turn and probably not reach the stall, when leading to mechanical lock body intelligence to lock or close the lock, can't confirm whether to the stall position, lead to can not unblank or close the lock.

Therefore, when the mechanical lock is powered up again after power failure, the mechanical lock needs to be recalibrated based on the calibration stroke in the initial use.

The method adopted by the recalibration is to obtain the absolute value of the difference of the code values when the mechanical lock body rotates to the locked rotor in two directions and compare the absolute value with the calibration stroke, and accordingly whether the mechanical lock body is successfully recalibrated is determined. Similar to the method described above for obtaining the calibration stroke of the mechanical lock.

Referring to fig. 10, fig. 10 is a schematic diagram of recalibration after power off according to an embodiment of the present application. Firstly, the mechanical lock body is rotated to a code value when in locked rotation in any direction to serve as a third code value, wherein the locked rotation is any one of locked rotation or unlocked rotation.

And then, rotating the mechanical lock body to the code value when in locked rotation in the opposite direction to be used as a fourth code value, and then calculating the absolute value of the difference value between the third code value and the fourth code value.

And finally, when the absolute value of the difference value of the third code value and the fourth code value is equal to the calibration stroke, the mechanical lock body is confirmed to be calibrated again.

In another embodiment, when the mechanical lock has been recalibrated to allow proper operation, a lock in-place threshold and indicator lights are provided in the faceplate to reduce damage to the mechanical lock. Wherein the lock body is locked in place and unlocked in place. Referring to fig. 11, fig. 11 is a schematic view of an unlocking position according to an embodiment of the present application. The unlocking in place refers to the position where the mechanical lock body is just opened, the position is a certain distance away from the unlocking locked rotor, and the distance is a first preset value. Referring to fig. 12, fig. 12 is a schematic view of locking in place according to an embodiment of the present disclosure. The locking position refers to a position where the mechanical lock body is just locked, and the position is a certain distance away from the unlocking locked rotor, and the distance is a second preset value. The first preset value and the second preset value are different according to different requirements of the mechanical lock body.

Wherein the mechanical lock body is already in an open state when the lock is in place. In order to avoid the damage of the lock body, at the moment, the indicator light is turned on to remind a user that the mechanical lock body is opened, and the mechanical lock body does not need to be continuously rotated. On one hand, the indicator light is used for prompting that the user door is opened or closed, and on the other hand, the mechanical lock body is prevented from being damaged due to the fact that the lock is locked or unlocked at every time. The situation of locking in place is the same as above, and is not described here.

It can be seen that the embodiments of the present application are based on the description of the embodiments of the method for detecting the stroke of the mechanical lock body, and the lock body and the faceplate are connected together by using the motor and a plurality of gears and an encoder. Firstly, a plurality of gears are driven by a motor to rotate a mechanical lock body, the mechanical lock body rotates to block rotation in two opposite directions, and an encoder is driven to encode to obtain a first encoding value and a second encoding value. And calculating the absolute value of the difference value of the first encoding value and the second encoding value to obtain the calibration stroke of the mechanical lock body. The stroke calibration of the mechanical lock body of the intelligent panel lock is realized by driving a plurality of gears and the encoder through the motor, the problem of incompatibility cannot be generated, and meanwhile, the intelligent mechanical lock can be adapted to most intelligent mechanical locks on the market. Meanwhile, the motor drives the gears and the encoder, so that the stroke can be calibrated, the position change condition of the lock body can be obtained according to the change of the encoding value, and the middle position of the stroke of the lock body can be determined through the encoder.

Firstly, a plurality of gears are driven by a motor to rotate a mechanical lock body, the mechanical lock body rotates to a locked state in two opposite directions, and an encoder is driven to encode, so that a first encoding value and a second encoding value are obtained. And calculating the absolute value of the difference value of the first code value and the second code value to obtain the calibration stroke of the mechanical lock body.
