Fig. 2 is a schematic block diagram of a specific structure of an intelligent door lock provided by an embodiment of the present invention. The whole door lock comprises three parts, namely an outer lock body, a door plate and an inner lock body.

The technical solution provided by the embodiments of the present invention is described below with reference to specific data.
Firstly, power consumption of a face recognition module:
and (3) measurement is realized: the starting time of the face recognition module is 1s, the starting current is 100mA, the face recognition time is 1 s: the current is 180mA during identification, and the system is standby for 3s after successful identification, and the standby current is 5 mA.
And (3) reserving a certain allowance: the face recognition module recognizes that the average current of the primary face image is 200mA, and the time is 5 s.
Selecting rated voltage and capacitance capacity of the super capacitor:
two main applications of supercapacitors are: high power pulse application and instantaneous power conservation. According to the face recognition intelligent lock characteristic, instantaneous power is kept.
The required supercapacitor capacity is calculated according to the following formula.
Keep the required energy = the energy of the supercapacitor reduction.
Energy required during hold =1/2I (Vwork + Vmin) t;
super-capacitor reduced energy =1/2C (Vwork 2-Vmin 2),
thus, the capacity (neglecting the voltage drop caused by IR) can be found to be:
C=(Vwork+ Vmin)It/( Vwork2 -Vmin2)。
wherein,
c (F) represents the nominal capacity of the super capacitor;
r (ohms) represents the nominal internal resistance of the supercapacitor;
ESR (ohms) represents equivalent series resistance at 1 KZ;
vwork (V) represents normal operating voltage;
vmin (v) represents a cutoff operation voltage;
t(s) represents the required duration of operation in the circuit;
i (a) represents the load current.
According to the specific power consumption requirement of the face recognition intelligent lock: the power consumption is 200mA, the duration is 5s, and the minimum working voltage is 3V.
The following can be obtained: c = (5+3) × 0.2 × 5/(52-32) =8/17= 0.47F;
according to the calculation result, considering that the internal resistance of the capacitor consumes a small part of energy in the discharging process, the capacitor can be selected to be 6V and 0.5F, and the requirement can be met.
When the specific energy storage unit is designed, because the energy stored by the single super capacitor is limited and the withstand voltage is not high, the capacity expansion is needed by a corresponding series connection and/or parallel connection method, so that the index of the super capacitor is achieved.
Thirdly, calculating the charging time of the super capacitor:
the charging time of the super capacitor is calculated according to the following formula:
C×dV=I×t
wherein C represents a capacitor rated capacity; v represents the capacitor operating voltage; i represents a capacitor charging current; t represents the capacitor charging time.
Therefore, for a super capacitor with 6V and 0.5F, the charging current is 500mA, and the charging time is as follows:
t =(C×dV)/I=(0.5×6)/0.5=6s
if the charging current is chosen to be 800mA, only 3.75s is required.
Fourthly, selecting a direct current micro motor:
the direct current micro generator adopting the brushless technology has the characteristics of small volume, large generated energy, low noise, long service life and the like, and the micro generator with 3-5W, 3V, 6V, 9V rated voltage and the like exists in the prior art.
According to the charging requirement of the super capacitor, a miniature generator with 3W, 6V rated voltage and 3000rpm rotating speed can be selected to meet the charging requirement.
When the speed-changing accelerating gear set in the door lock is designed, 3-5 transmission ratios (or higher transmission ratios to achieve the required rotating speed) can be used, the generator can be driven at the rotating speed of 50rps, and the lock handle rotates in about 6 s. If a micro generator with higher power is selected, the electric quantity required by the face recognition module to finish one-time recognition can be sent out in less time.
Therefore, the embodiment of the utility model provides a rotate the charge running gear through the lock handle, drive the gear train and produce certain rotational speed, as long as reach 50rps, the time is 6s-10s, can produce face identification once and control the required consumption of opening the lock promptly.
To sum up, the embodiment of the utility model provides a modular design simple structure, simple to operate. The power supply comprises a self-generating module, an energy storage unit and a power supply management unit, the trouble of battery replacement caused by long-term use of the door lock and power supply is solved, the handle is rotated each time to generate power, and the power is stored for identification and use each time. The self-generating module adopts a handle to rotate to drive the gear set, and the gear transmission ratio is adjusted to meet the requirement of rotating speed required by power generation; the energy storage unit adopts the super capacitor, and the number of the super capacitors in series and parallel connection can be adjusted, so that the requirements of power consumption and input voltage of the face door lock are met. The whole machine and the circuit structure are simple, and the self-generating face recognition intelligent door lock is realized.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
