Specifically, the electrical energy storage device is used for storing electrical energy; the generator is used for converting mechanical energy into electric energy; the transmission mechanism is respectively connected to the main shaft and the input shaft of the generator so that the main shaft can drive the input shaft of the generator to rotate when rotating; the electric energy storage device is electrically connected to the controller and the motor to supply power to the controller and the motor, and the generator is electrically connected with the electric energy storage device.

As a specific solution, the transmission mechanism may be formed by a set of meshing bevel gears. The electrical energy storage device may include a lithium battery as a backup power source, and in order to prevent a failure of the lithium battery, the electrical energy storage device may employ a super capacitor as a backup device. The circuit board is provided with a plurality of circuits such as a charging circuit, a voltage stabilizing circuit and the like, electric energy generated when the generator is rotated is preferentially stored in the super capacitor, and a stable voltage is generated by the super capacitor, so that the lithium battery is charged under the condition of surplus electric energy.

As an expansion scheme, electric energy generated by the generator is preferentially supplied to the controller and peripheral circuits thereof to electrify the controller, a voltage detection circuit is arranged on the circuit board and feeds the voltage of the lithium battery and the capacitor back to the controller, and if the controller finds that the electric quantity of the lithium battery is less and the electric quantity of the capacitor is less, a charging loop for charging the lithium battery by the capacitor is firstly disconnected, and the electric quantity is preferentially supplied to the controller.

As a specific control scheme, the method comprises the following steps:

powering on the controller;

detecting the voltage of the lithium battery, if the voltage is greater than a threshold value, switching to an identity identification program, and if the voltage is less than the threshold value, detecting the voltage of a capacitor;

if the voltage of the capacitor is less than the threshold value, prompting a message to the user to further shake the handle;

if the voltage of the capacitor is greater than the threshold, an identification procedure is entered.

As a preferred scheme, when the controller is powered on, the controller immediately controls the fingerprint sensor to collect a frame of fingerprint image data.

In addition, when the voltage of the capacitor is larger than the threshold value, the controller controls the communication module to send out a packet with insufficient battery voltage.

Preferably, the main shaft is connected with the input shaft of the generator through a ratchet device, that is, rotating the handle drives the main shaft to rotate, and the main shaft drives the input shaft of the generator to rotate, but the handle does not drive the generator reversely when rotating.

In addition, in order to support the main shaft, a bearing and other devices are also arranged, and as a specific scheme, the main shaft penetrates through the position encoder and is sleeved in the bearing.

In order to make the handle feel, a damper can be arranged and connected to the main shaft, so that the handle can not be too flexible in rotation.

Specifically, the controller is mounted on the circuit board; fingerprint sensor, position encoder, motor and electric energy storage device all electric connection to circuit board.

Specifically, the intelligent fingerprint door lock device further includes: and the rotating position indicating device is used for indicating the rotating position of the handle. As a general scheme, an indicating dial having a general pattern may be used.

As another scheme, the rotating position indicating device comprises a plurality of LED lamps arranged along the circumference, the LED lamps are electrically connected to the circuit board so that the electric energy storage device supplies power to the LED lamps, and the controller can control the LED lamps according to the position data of the position encoder. Namely, when the handle is rotated to a certain position, the corresponding indicator light of the position can be lightened.

The door lock communication module is electrically connected to the circuit board so that the controller can form data interaction with the outside through the door lock communication module.

When a user opens the door, the user holds the handle and rotates to a set circumferential position corresponding to the user, wherein the set circumferential position can be one circumferential position or a plurality of circumferential positions, and the complexity can be set according to the safety level required by the user.

In addition, as the set mode, a sequential mode and a non-sequential mode may be adopted.

The sequential mode means that unlocking or permission acquisition can be realized only when the user passes through the circumferential positions according to a set rotation sequence.

The non-sequential mode means that the user can unlock or acquire the authority only by rotating the handle through all set circumferential positions.

Preferably, the door lock device of the present application can be selected in such a manner that unlocking can be achieved only by turning the handle, but only a sequential mode can be selected in the mode, and the number of circumferential positions must exceed 9, and three circumferential positions adjacent in sequence must satisfy at least one turning direction. When the specific setting is carried out, voice prompt can be adopted, so that the user can set the setting and meet the setting requirement.

Preferably, the controller is normally in a low power mode in which it is powered up, and upon receipt of a position encoder signal, it begins the operating mode, increasing the operating frequency and activating the corresponding circuitry and devices.

The controller receives the signal of the position encoder when the battery electric quantity is low, preferentially feeds back an alarm signal to the user, informs the user to rotate the handle for multiple times to obtain enough electric energy, does not record the circumferential position of the handle at the moment, and prompts the user to determine the circumferential position after the controller detects that the capacitor obtains enough electric energy.

When the data of the circumferential position and the fingerprint data are collected by the controller and are matched, the motor is driven to carry out unlocking action, and if the controller detects that the electric quantity is not enough for the motor to complete the door opening action after the user identity identification is completed, the controller informs the user to shake the handle for a plurality of times again through indicating lamps or voices and other modes, so that enough electric quantity is obtained.

As another scheme, the door lock device of the application is further provided with an alarm mode, namely, under the condition that fingerprint identification is passed, a user sets a group of specific circumferential positions, at the moment, the door lock can be normally opened, but the controller can be accessed to a WiFi network through a communication module after receiving data of the group of circumferential positions, so that a distress signal is sent to the server, and the server sends the distress signal to a 110 platform and the like after receiving the data of the group of circumferential positions

The scheme has the advantages that the defect that only the fingerprint lock is possibly cracked is firstly enhanced, in addition, the endurance time of the door lock is increased by combining the unlocking action power generation system, the inherent electric quantity in the lithium battery is rarely consumed in a general unlocking procedure, and the anti-hijack function is completed under the condition that no one knows by other people through the alarm mode.

As another aspect of the present application, the present application discloses a method of controlling an intelligent fingerprint door lock device.

The method specifically comprises the following steps:

collecting circumferential position data of the handle;

judging whether the circumferential position data of the handle exceeds a preset starting position or not; if it is exceeded, the next step is carried out, if not, the previous step is returned, which has the advantage that the placing handle is touched by mistake.

Judge whether the circumference position of handle is in the identification position, when concrete operation, the user as long as it satisfies 0.3 second to pause at specific circumference position, can gather effectual circumference position data, for the time of controlling higher sampling frequency 0.3 second enough collection, for better making the user learn to have gathered, can set up the gear and the pilot lamp of certain circumference position, only set up the sampling point of circumference data and make the instruction in the gear department of circumference position, be equipped with corresponding gear as cooperation damping device, can obviously feel the resistance increase and clear gear sense when rotating these circumference positions, also can cancel the pilot lamp this moment.

The main shaft is provided with a plurality of grooves, and the steel balls can be embedded into the grooves when the main shaft rotates to a gear.

When the handle meets all identified circumferential positions, or meets both the circumferential positions and the sequence, the ID of the corresponding user is found according to the code corresponding to the circumferential data, and the fingerprint data under the ID is called to be compared with the existing fingerprint data. As a more optimized scheme, after the data at the circumferential position is satisfied, only the permission of fingerprint comparison is opened, and information such as ID, fingerprints and the like of a user does not need to be called, and the comparison is directly carried out in an index mode.

As a specific scheme, the common family members do not need to call IDs and fingerprints, and the family members directly perform sequencing comparison in the pre-stored family data group according to the use frequency, so that the family members can use the same circumferential position data. For a temporary visitor, a user ID is required to be found and a fingerprint is called, and the calling data can be originated from a server, and the circumference data and the user ID are in one-to-one correspondence.
