Description

Door lock {Door lock}

      In the embodiment of the present invention, power generation is performed using solar heat collection means to control the charging and charging timings of the charging means, and the charging power is used for the locking device to increase the period of use of the charging means to reduce generation of waste battery electricity .

      In general, a battery used for operating a locking apparatus is a general battery that can not be charged, and a digital lock is widely used due to the development of a lock, which is a locking device. Is increasing.

     There is no theory about the security effect of the digital lock with its convenience and high security, but it is inevitably necessary to use a DC power source, for example, a power source of 6 volts (V) This power is solved by using AA type battery.

     In the structure of the digital lock device, when an accurate signal by the password signal system is inputted using the small DC drive motor, opening / locking is realized by operation of the DC drive motor (17 in FIG. 6).

Here, the operation is realized by a coupling operation composed of a control part (16 in Fig. 6) which is a necessary and sufficient condition, a peripheral electronic component for driving it, and a direct drive motor for realizing direct physical operation. V batteries.

There are various kinds of digital lock devices widely used in Korea. However, most of the products have battery life of one year, and when the battery is actually used, the discharge end voltage of the battery does not exceed one year, and the replacement time comes.

As of 2013, about 9 million digital locks have been distributed throughout the country in terms of the number of digital locks distributed nationwide.

Under this circumstance, all digital locks currently in use are due to replace the battery once a year. If you replace the four batteries with a one-year cycle, then 36 million batteries will be generated annually by arithmetic calculations.

Currently, the collection rate of waste batteries in Korea is only 3% of the total quantity. It is gradually getting better through publicity and enlightenment, but it is not escaped to a slight level and it is mixed with general garbage and is buried without any measures.

In terms of the composition of the battery itself, more than 300 tons of 100% imported metal materials such as zinc, aluminum, and tin are used and a large amount of mercury is used during the charging process. If the waste is discarded without any measures and it is mixed with the general garbage, if the landfill is continued, there will be economic loss due to the waste factors such as imported nonferrous metals such as zinc and aluminum and contamination of mercury in the decomposition process occurring after the metal is buried. There is concern about groundwater pollution caused by leachate.

It is an object of the present invention to provide electric power obtained by using solar power generation, which is renewable energy, as a charging voltage of a rechargeable battery of a locking device.

The embodiment proposes that a solar panel used for solar power generation constitutes a cooling means for cooling the solar panel so as to generate power under optimum conditions.

The embodiment proposes a circuit operation for stopping the charging by controlling the overcharge control switching means based on the control unit and charging (Over charge), while charging the generated power based on the solar heat collecting plate.

The embodiment proposes that the charge start / charge stop timing is determined so that the charging means is charged at the optimum condition under the power generated by the solar heat collecting plate, and the charging operation is performed accordingly.

A method of operating a locking device using solar power generation according to an embodiment includes the steps of: setting a predetermined charging starting and stopping point in the means (16a) for indicating charging start and stopping timings; Charging the charging means (14, 15) through the charge control switching means (18) by the electric power generated by the solar heat collection means (1); Determining whether the charging stop timing is a predetermined one based on the control unit (16); Outputting a signal (high) corresponding to the charge stop timing to the charge time control switching means (20) in the means for notifying the charge stop timing based on the result of the check; The charging time control switching means 20 being turned on; Turning off the charge control switching means (18) as the charge time control switch means is turned on; And stopping the charging of the charging means (14, 15) by the current due to the solar power generation when the charging control switching means (18) is turned off.

Since the rechargeable battery according to the embodiment of the present invention is used, the sub voltage due to the solar power generation is charged by the rechargeable battery, so that the period of use of the rechargeable battery is increased so that the generation time of the rechargeable battery becomes longer, Can be reduced.

That is, the conventional digital locking device is limited to one year of use of the battery, and there is a serious problem that about 36 million pieces of waste batteries are generated annually. However, there is an effect of reducing the generation of waste batteries per year. In addition, it can reduce the annual generation of waste batteries, save more than 300 tons of zinc and aluminum, which are 100% imported raw materials, and reduce pollution of soil and groundwater due to mercury spillage after landfilling.

FIG.

Hereinafter, embodiments of the present invention will be described with reference to Figs. 1 to 5. Fig.

1 and 2, a solar heat collecting plate 1 of 65 mm × 130 mm in length is installed on an outdoor case cover 3 located in an outdoor case 2 of a digital door lock apparatus. When installing a special die casting mold, first calculate the area of the heat sink required capacity and then prepare the space and adhesive surface.

The calculation of the area of the required capacity for the solar panel is as follows.

Solar panel type: Thin-film solar panel Size: 65mm × 130m

Specification Inside collection piece (cell) Size: 11.5mm × 18.5mm width Quantity: 30cell.

The DC voltage and current that can be generated in the thin film type solar collector plate of the above standard are as follows. Considering the possibility of sunlight contact with the solar panel in the spring, summer, autumn, winter and four seasons, the average time for 7 hours is calculated considering the differentiating temperatures of each season. It is calculated that voltage and current can be generated.

Maximum output: 0.8 W, Maximum voltage: 6.5 V, Maximum current: 80 mA, Open voltage: 6.2 V

As shown in Figs. 1 and 2, in the solar heat collecting plate installed in the outdoor case cover 3, the voltage and current are generated as described above and the indoor case (Fig. 4 4 and 5 built in the battery charger 8, so that the power required for the digital door locking device can be solved.

As shown in Figs. 1 and 2, the angle (1) of the solar collector plate installed in the outdoor case cover (2) of the digital door lock device for a general residence (corridor type apartment) and the tempered glass door When set at a 4 degree tilt from vertical, it is ideally in contact with sunlight and maximizes power generation capacity at an angle that matches the characteristics of the collector plate.

The reason why the angle of the solar heat collecting plate provided on the outdoor case cover 2 of the digital door lock device is set to be inclined by 4 degrees from the vertical is as follows. As the highest efficiency occurs when the junction angle of the heat collecting plate 1 is 42 degrees, in the embodiment of the present invention, the angle of the solar light collecting plate attached to the outdoor case cover is squared to maximize the efficiency.

As described above, the voltage and current supplied to the rechargeable batteries 5 and 14 are supplied with the maximum open-circuit voltage of 6.2 V and 80 mA, so that the voltages of four (14) series-connected rechargeable batteries 6V, no reverse current is generated, and when the charging time is 7 hours per day, the charging current and voltage required by the charging battery built in the embodiment of the present invention can be supplied smoothly, If the specification of the rechargeable battery that has been discharged reaches the discharge end voltage (the voltage value at the time when the battery reaches the state where it can not output by long repeated use), the self recovery voltage The life of the product can be guaranteed with the rechargeable battery which is supplied together with the present embodiment.

When the average daily use frequency of digital door lock system is converted into 25 average, the voltage and current consumed in one operation are as follows.

Driving motor: Minimum rated voltage: DC 3 VOLT, Minimum rated current: 350 mA

           Driving time when power is applied by mounting on door lock device: 0.4 / sec

Password input button Check LED × 4 consumption Minimum voltage, current: DC 2.8V 60mA

Main control board components and CPU operating minimum voltage: DC 2.8 VOLT, minimum current: 60 mA

In the normal state of the embodiment of the present invention, except for the charging circuit, the remaining current and voltage are consumed in the single operation due to the operation of the user in the state where all the circuits and parts are kept in the SLEEP MODE. After operation, the battery is returned to the initial state and switched to SLEEP MODE to prevent the loss of current, thereby significantly reducing the number of times of charging and discharging of the self-rechargeable battery, thereby extending the life of the rechargeable battery. It is structured to reduce its lifetime by repeating full charge and discharge repeatedly.

FIG. 3 is a side view illustrating a position and an external appearance of a digital door lock apparatus according to an embodiment of the present invention in which a cooling means for cooling a solar heat collection plate is installed.

As shown in FIG. 3, the cooling means for cooling the solar heat collecting plate 1 attached to the outdoor case has a structure in which the ventilation means 10 for cooling circulation is provided on the bottom surface of the cover 3 on which the heat collecting plate 1 is attached, The cooling air can be circulated at the time of the case cover operation or at the usual time, and the cooling effect of the heat collecting plate can be generated.

A solar panel is attached to a case cover, which is part of an outdoor case configuration in which an input part (not shown) for inputting a unique password of the digital door lock constitutes, and in order for an actual solar panel to receive optimal sunlight, Is a cooling function for the heat collecting plate.

The DC voltage and the current generated by the solar collector plate 1 fixed to the case cover 3 of the outdoor case 2 installed outdoors are transmitted to the outside through the connection wiring 7 connecting the various power and signals of the indoor equipment Is supplied to the rechargeable battery (5) built in the indoor case (8), thereby operating the device operation board (9) and the drive motor (6).

Hereinafter, the embodiments of FIGS. 1 to 5 described above will be supplementarily described.

(1, 2, 3 & 4) installed outdoors for operation of a door lock device, and a door lock device (Figures 4 and 5) installed in the room, An outdoor case 2 to which an input unit (not shown) for inputting information on the door locking device is coupled; An outdoor case cover (3) coupled to the outdoor case (2); A solar heat collecting means (1) coupled to an upper surface of the outdoor case cover; And a cooling means (10) provided below the solar heat collecting means and cooling the solar heat collecting means formed on both sides of a predetermined position of the outdoor case cover (3), for example, immediately below .

The cooling means 10 for cooling the solar heat collecting means 1 is provided on at least one surface of the outdoor case cover 3 to be combined with the solar heat collecting means 1 As shown in FIG.

The cooling means 10 is formed on a plurality of surfaces from among the respective surfaces of the outdoor case cover 3 coupled to the lower portion of the solar heat collecting means 1, Particularly, the plurality of surfaces are surfaces facing each other (corresponding to each other) so that the air can communicate well, and the corresponding surfaces are provided with a predetermined shape (for example, a circle, a square , Pentagonal, hexagonal, etc.) are formed respectively at the inlet 10 and the outlet (not shown).

FIG. 6 is a view showing a charge / discharge and operation circuit of a door lock apparatus according to an embodiment of the present invention, and FIG. 7 is a flowchart showing that charging start and stop according to the charging point timing according to the embodiment of the present invention is performed. to be.

Hereinafter, an embodiment of the present invention will be described with reference to Figs. 6 and 7. Fig.

As shown in Fig. 6, charging and power-off operations in the door lock device including the charging power source 14 and / or 15 connected to the solar heat collection means 1 and the control unit 16 (main CPU) The circuit unit 12 includes TR (18) as charge control switching means connected to the solar heat collecting means (1); When the power supply is applied to the base terminal of the charge control switching means 18 and the switching means 18 is turned on, the charging means 14 or / and 16 for charging the current generated and output by the solar heat collecting means 15); And a switching means for switching at least above the voltage corresponding to the full charging voltage of the charging means (14) to stop charging, in particular when the charging in the charging means (14) is overcharged And a TR (18) which is switching means operated in accordance with the operation of the Zener diode (23) and the zener switching means (23).

The operation of the switching means 18 is turned off because no power is applied to the base terminal of the charging control switching means 18 based on the operation of the overcharge control switching means 24, The electric current outputted from the solar heat collecting means 1 is not inputted to the charging means 14, 15 and the charging is stopped.

A counter 16a as a means for notifying the predetermined charging timing and the stop timing; And TR (20) which is a charging time control switching means operated on the basis of a signal of the means for notifying the charging timing and the stop timing, wherein the signal (16a) of the means (16a) When the output is a signal for stopping the charging (for example, high), the operation of the charging time control switching means 20 is turned on and the input current is bypassed, The current is not applied to the base terminal and the operation of the charge control switching means 18 is turned off so that the current outputted from the solar heat collecting means 1 is not inputted to the charging means 14 and 15 and the charging operation is stopped.

On the other hand, when the signal output from the means 16a for notifying the charging timing and the stop timing is a signal for starting charging (for example, low), the operation of the charging time control switching means 20 is turned off, The current is applied to the base terminal of the charge control switching means 18 and the operation is turned on so that the current outputted from the solar heat collecting means 1 is input to the charging means 14 and 15 to start the charging operation.

A controller (16) for controlling the counter (16a) which is a means for notifying the predetermined charging timing and the stop timing; And motor drive control switch means (21) whose operation is controlled based on a signal of the control portion to control operation of a motor (17) for door lock operation; .

When the user inputs information to enter the house through an input unit (not shown) of the door lock device, the control unit can output a signal through confirmation with information previously stored in a memory unit (not shown) The motor drive control switch means 21 is turned on, the power of the auxiliary power source 15 is applied, and the door lock apparatus is operated through the motor drive.

The diode 22 of FIG. 6 serves to protect the charge control switching means 18 through prevention of counter electromotive force between the terminals of the motor by the motor self-coils.

FIG. 7 is a flowchart showing charging start and stop according to the charging point timing according to the embodiment of the present invention.

As shown in Fig. 7, in the method for controlling the charging time of the charging means, predetermined charging start and stop points are set in the means 16a for notifying the charging start and stop timing. (S701)

For example, it is possible to use the rechargeable battery for a long period of time by protecting the charging means from being repeatedly turned on and off at intervals of 30 minutes to 50 minutes rather than being supplied for a long time. It is not the optimal charging method. Therefore, in the embodiment, the cycle of the counter 16a circuit is set to the sleep mode for 35 minutes and 15 minutes for charging.

It is determined whether or not the charging stopping timing is the predetermined charging stopping timing while the charging means 14 and 15 are being charged by the charging control switching means 18 by the electric power generated by the solar heat collecting means 1 , A signal (high) corresponding to the charge stop timing is outputted to the charge time control switching means (20) by the means for notifying the charge stop timing. Therefore, as the charging time control switching means 20 is turned on, the charging control switching means 18 is turned off (S 705, S 707, S 709, S 711).

When the charging control switching means 18 is turned off, the charging of the charging means 14 and 15 by the solar power generation is stopped (S713)

On the other hand, the means 16a for notifying the charging start timing of the charging start timing based on the checking result by the control unit 16 judges whether or not the signal corresponding to the charging start timing is supplied to the charging time control switching means 20 low, the charging time control switching means 20 is turned off and the charging control switching means 18 is turned on. (S 715, S 717, S 719, S 721)

Therefore, when the charge control switching means 18 is turned on, charging of the charging means 14, 15 with the current due to solar power generation is started. (S723)

6 and Fig. 7 will be described.

The reason why the Zener diode 23 is present in FIG. 6 is that the Zener diode 23 is fully charged to the rechargeable battery at a capacity of 6.2 volts and flows to the Zener diode cat sword when a power of 6.2 volts or more is output from the rechargeable battery. When a zener diode is applied to the cat sod more than its own capacity, the current flows in the reverse direction from the forward direction.

When the current flows in the reverse direction from the Zener diode in the circuit configuration of the embodiment of the present invention, the charging control switching TR 18 is turned off while the overcharge control switching TR 19 is turned on (turned on) It prevents the current from flowing to the rechargeable battery.

The capacitor 15, which is one of the charging means, also has a function of detecting the capacitor, compensating the pulsating current of the DC power source, and discharging after the voltage condensing. In the embodiment of the present invention, when the instantaneous operating voltage of the driving motor is max 350 mA, if the capacitor is about 10,000 MICRO, it is possible to charge time 0.2 / SEC and sufficient sub power source 15 can be supplied through instantaneous discharge when the motor is driven. 14) can contribute to long use.

Therefore, it is possible to control the charge voltage of the container to be used first as a power source for driving the motor based on the control of the control unit. As a result, the battery which is the main power source 14 can be used for a long time, And can be greatly contributed to the environment by reducing the amount of waste batteries in particular.

In the embodiment of the present invention, unnecessary power waste is minimized by controlling 15 / min interval charge, which is the optimum environment of the charge control circuit 12, and the idle voltage is condensed into 10,000 micro condenser, It is used as sub voltage in lock operation.

In the conventional door lock system, four batteries are connected in series, and four batteries are generated in one set of door locks in a year. Example of the Present Invention When the sub voltage due to the solar power generation in the structure is charged by using the rechargeable battery, it is possible to use about 2 years and 5 months when assuming about 40 times of use per day. Therefore, it means that the period of use of the battery is increased so much, and the point of time when the battery is generated is longer, which can be reduced by more than 70%.

In addition, when the battery is used as a power source of a digital door lock by using the power obtained by using solar power generated by renewable energy as a charging voltage of a rechargeable battery, it is possible to use the rechargeable battery as a rechargeable battery To change

By charging with solar power generation, which is a new and renewable energy, the battery life can be increased to 2 years and 5 months, so that the generation of waste batteries can be reduced naturally.

The number of times the rechargeable battery is recharged after a complete discharge where the number of repeated charging reaches the discharge end voltage is about 800 times. Since the charging method of the present invention is not a method of recharging after a complete discharge but an appropriate voltage maintaining progressive charging method by solar power generation, a complete discharge does not occur and does not correspond to the number of times of recharging.

In general households, when the number of daily use is usually 4 or more, it is calculated 30 times in about 20 times a day. In the case of the embodiment, the number of times of use per day is calculated to be 40 times. When using the alkaline battery, When the voltage is reached, the battery replacement alarm sounds. At this time, 4 replacement batteries will be generated and 3% reduction in the amount of waste batteries in Korea. The remaining 97% is reclaimed along with the general waste without any preparation. This is one of the causes of groundwater pollution and soil pollution caused by leachate.

Therefore, if the rechargeable battery of the present invention is used, the battery life of the digital door lock, which is the power source of the digital door lock, can be about 2 years and 5 months (70%).
