2) When the smart terminal 150a is registered as a user key in the dual interface NFC tag 200 of the corresponding door lock 120, the smart terminal 150a tags the corresponding dual interface NFC tag 200, the corresponding The dual interface NFC tag 200 records the ID (ID) and the open/close signal of the smart terminal 150a according to the tagging in the memory 220, the ID (ID) of the tagged smart terminal 150a and the pre-registered smart When the IDs of the terminals 150a are compared and matched, the opening/closing signal recorded in the memory 220 is transmitted to the corresponding door lock 120, and the control unit 310 performs opening/closing operation according to the received opening/closing signal. By controlling the unit 320, the door 130 is locked or opened (released).

As shown in Figure 2b, the corresponding dual-interface NFC tag 200, records the open/close signal of the corresponding door lock 120 in the memory 220, the dual-interface NFC tag of the smart terminal 150a after the recording By tagging the 200, the opening/closing signal recorded in the memory 220 is transmitted to the corresponding door lock 120.

The smart terminal 150a is a terminal performing wireless communication with the dual interface NFC tag 200 . Smart terminal 150a may also be referred to as a subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, user device, or user equipment (UE). The smart terminal 150a may be a cellular phone, a wireless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless access capability, a computing device, or a wireless modem. It may also be another processing device connected to However, the smart terminal 150a should not be limited by being limited to these terms. The smart terminal 150a should be understood as any device including an NFC module, which is an active device for short-range wireless communication with the dual interface NFC tag 200 . The smart terminal 150a performs short-range wireless communication with the dual interface NFC tag 200 through the antenna 210 of the dual interface NFC tag 200 .

The dual interface NFC tag 200 performs short-range wireless communication with the smart terminal 150a, and performs wired communication with the control unit 310 of the door lock 120 . For example, wired communication includes serial communication, USB communication, I2C communication, SPI communication, and the like.

The antenna 210 for the RF interface transmits/receives a signal according to a radio frequency in the air as if a wire is connected, and the antenna 210 supports wireless short-range (eg, 10 cm) communication. do.

In general, the antenna 210 is configured as a loop antenna, and the loop antenna may be implemented as a PCB, an FPCB, or a general conductive wire.

The memory 220 for data storage is generally a non-volatile memory (NVM) and may be, for example, an electrically erasable programmable read-only memory (EEPROM). When implemented as an EEPROM, internal data is erased by applying an electrical signal to the memory 220, so a dedicated eraser for data erasing is not required, and writing and erasing can be performed using a single writer. Such an EEPROM may have a limit of the number of repeated writes of about 1 million times.

In addition, the ports 230 for wired communication may include ports for receiving data from the control unit 310 of the door lock 120 . For example, in the case of I2C wired communication, the control unit 310 through wired communication through a serial clock (SCL) port and/or a serial data (SDA) port to the memory 220 of the dual interface NFC tag 200. data can be recorded.

Ports 230 for wired communication, a first port for recognizing the tag of the smart terminal 150a for the corresponding dual interface NFC tag 200; and a second port for recognizing a write to the corresponding dual interface NFC tag 200 from the smart terminal 150a.

The first port may include an Energy Harvest Field Detection (EH_FD) port, and the second port may include a Radio Frequency Write In Progress (RF_WIP) port.

The first port and the second port may be coupled to each other. In this case, the coupling may use the output of the first port as a control signal for controlling the enable and disable of the pull-up resistor of the second port.

The combined signal of the first port and the second port may be used as an interrupt signal for the control unit 310 .

When the interrupt signal is toggled from low to high and a predetermined time for determining tagging validity has elapsed, the control unit 310 controls the corresponding It can be recognized as tagging for the dual interface NFC tag 200 .

In addition, when the interrupt signal is toggled from high to low and a predetermined time for determining the end of the event elapses, the control unit 310 releases the tag from the dual interface NFC tag 200 of the smart terminal 150a can be recognized as

In addition, when the interrupt signal is toggled from high to low and then toggled from low to high again within a predetermined time period, the control unit 310 controls the memory 220 of the dual interface NFC tag 200 . It can be recognized as a write of the smart terminal 150a.

Also, when the interrupt signal is toggled from high to low and then toggled from low to high again within a threshold time, the control unit 310 may recognize an invalid operation.

On the other hand, the operating characteristics of the first port for recognizing the tagging of the smart terminal 150a for the dual interface NFC tag 200 is as follows.

The dual interface NFC tag 200 may receive operating power from the smart terminal 150a. The smart terminal 150a generates an electromagnetic field, and when the smart terminal 150a approaches the dual interface NFC tag 200 within a certain range, the generated electromagnetic field operates as the operating power of the dual interface NFC tag 200 . The first port is a port for detecting the presence or absence of the electromagnetic field of the aforementioned smart terminal 150a, and when the presence of the electromagnetic field is confirmed, the signal waveform is toggled-up.

Since the dual interface NFC tag 200 is connected to the door lock 120 through wired communication, in some cases, it may receive operating power from the door lock 120 through a wired line.

In addition, the operating characteristics of the second port for recognizing the write to the dual interface NFC tag 200 from the smart terminal 150a are as follows.

When the smart terminal 150a performs a writing operation on the memory 220 of the dual interface NFC tag 200 while the dual interface NFC tag 200 is receiving operating power from the smart terminal 150a, , The signal waveform that has been toggled up is toggled down, and after a certain time has elapsed, the signal waveform is toggled up again.

The second port detects that the smart terminal 150a has performed writing to the memory 220 of the dual interface NFC tag 200 by detecting that the toggle-up signal waveform is toggled down and toggled up again. can do.

Ports 230 for wired communication including the aforementioned first and second ports support wired communication with the door lock 120 . Specifically, the ports 230 for wired communication are connected to the control unit (MCU, 310) of the door lock 120 by a wired line. The door lock 120 includes a control unit 310 , and the control unit 310 performs wired communication with the dual interface NFC tag 200 .

As described above, the smart terminal 150a may perform writing and reading through wireless short-range communication with respect to the memory 220 of the dual interface NFC tag 200, and the door lock 120 is the dual interface NFC tag 200 ) of the memory 220 may be written and read through wired communication. That is, the smart terminal 150a and the door lock 120 share the memory 220 of the dual interface NFC tag 200 with each other. For example, when the smart terminal 150a records the opening/closing signal in the memory 220 by tagging the dual interface NFC tag 200, the control unit 310 of the door lock 120 opens and closes recorded in the memory 220 The signal is read, and if it is a preset open/close signal, the door 130 is opened and closed by controlling the opening/closing operation unit 320 .

However, since the smart terminal 150a and the door lock 120 communicate with each other in a memory sharing method rather than a traditional communication method, the door lock 120 determines whether the smart terminal 150a is tagged or untagged, the smart terminal 150a ), there was no way to recognize whether data was recorded or not. Accordingly, the present invention is to provide a method for the door lock 120 to recognize the operation of the smart terminal (150a).

According to the present invention, by generating an interrupt for the control unit 310 of the door lock 120, the door lock 120 can recognize whether the operation of the smart terminal 150a and the type of operation. For interrupt, the present invention uses a combination of a first port for recognizing the tagging of the smart terminal 150a and a second port for recognizing a write to the dual interface NFC tag 200 from the smart terminal 150a. As described above, the first port may typically be an EH_FD port, and the second port may typically be an RF_WIP port.

The coupling method of the first port and the second port uses the output of the first port as a control signal for controlling the enable and disable of the pull-up resistor of the second port is used. . In order to describe a coupling method of the first port and the second port, first reference will be made to FIGS. 7 and 8 .

7 and 8 are circuit diagrams for explaining the coupling of the first port and the second port of the door lock according to an embodiment of the present invention.

7 and 8, the first port is an EH_FD port and the second port is an RF_WIP port.

When the smart terminal 150a is tagged with the dual interface NFC tag 200, the IC of the dual interface NFC tag 200 is powered by an electromagnetic field generated by the smart terminal 150a. The generated power is output to EH_FD of the IC of the dual interface NFC tag 200 in FIGS. 7 and 8 . The output of EH_FD may be input to the VCC port of the dual interface NFC tag 200 IC to be used as operating power, and may also be utilized as a signal for recognizing the state that the smart terminal 150a is tagged.

The RF_WIP signal is output from the smart terminal 150a to the IC of the dual interface NFC tag 200 when data recording occurs in the tagging state, the output is toggled from high to low, and after a certain period of time has elapsed, the output goes from low to high again. This is a signal that toggles up to and indicates that a recording has occurred.

These RF_WIP ports are basically open-drain ports. An open-drain port cannot generate an output without a pull-up resistor outside the port due to its characteristics. Here, RF_WIP is a signal that cannot be generated when EH_FD is low because a write operation is generated on the assumption that the smart terminal is tagged. Accordingly, the EH_FD port and the RF_WIP port are combined so that the enable of the pull-up resistor of the RF_WIP can be controlled according to the EH_FD signal in FIGS. 7 and 8 . That is, in FIGS. 7 and 8 , the RF_WIP output of the dual interface NFC tag 200 IC and the output signal of the GEN INT stage are configured as EH_FD + RF_WIP, which is a combination of EH_FD and RF_WIP.

The resistance R11 of the output terminal of GEN INT is the collector resistance of the transistor Q2 and the pull-up resistance of RF_WIP. When EH_FH is low in GEN INT, the output transistor Q2 conducts and the EH_FD + RF_WIP node is connected to GND, so R11 does not operate as a pull-up resistor. When EH_FD is high, the output transistor Q2 does not conduct, so R11 can operate as a pull-up resistor, and EH_FD + RF-WIP becomes high to recognize that the smart terminal is tagged. When data write occurs from 150a, the EH_FD + RF_WIP signal toggles low for a predetermined time and then toggles high again, indicating that a write operation has occurred.

3A is a configuration diagram schematically illustrating the configuration of a fingerprint recognition unit according to an embodiment of the present invention.

Referring to FIG. 3A , the fingerprint recognition unit 123 according to an embodiment of the present invention includes a fingerprint sensor 31 , a bezel 32 , a PCB board 33 , a fixing hole 34 , a connector 35 , and a component. It includes a mounting area 36 and a circuit 37 .

In Figure 3a (a) shows the configuration of the top (Top) surface, (b) shows the configuration of the bottom (Bottom) surface, (c) shows a cross-section viewed from the side (side) will be.

The fingerprint sensor 31 detects the user's fingerprint 150d and generates a fingerprint image. Here, the fingerprint sensor 31 may be, for example, a capacitive type fingerprint sensor, or a high-performance fingerprint sensor of 160 × 160 pixels. Therefore, the fingerprint sensor 31 cannot authenticate a forged fingerprint made of a non-conductive rubber material. In addition, the fingerprint sensor 31 consumes approximately 30 μA of current in the Sleep mode.

The bezel 32 fixes and supports the fingerprint sensor 31 in the form of enclosing the fingerprint sensor 31 .

The PCB board 33 has a conductive wire connecting the fingerprint sensor 31 and the circuit 37 in the form of a pattern.

Figure 3b is a view for explaining an interrupt for recognizing the tag of the smart terminal for the dual interface NFC tag of the door lock according to an embodiment of the present invention.

As described above, a combined signal in which the signal of the first port and the second port is combined is used as an interrupt signal for the control unit 310 of the door lock 120 . The first port may be, for example, an EH_FD port as a port for recognizing the tagging of the smart terminal 150a for the dual interface NFC tag 200, and the second port is the dual interface NFC tag from the smart terminal 150a ( 200) as a port for recognizing a record, for example, may be an RF_WIP port.

As shown in FIG. 3B, when the combined signal of the first port and the second port is toggled from low to high, and a predetermined time for determining tagging validity has elapsed, the control unit 310 is recognized as tagging of the smart terminal 150a for the dual interface NFC tag 200 .

The reason for introducing the predetermined time for determining the validity of tagging is that the signal waveform is not stably toggled up during tagging of the smart terminal 150a and some degree of chopping occurs. Furthermore, since tagging uses a non-contact RF method, the possibility of such chopping is greater. Therefore, the present invention introduces a predetermined time for the tagging validity judgment to detect only valid tagging. Although it may be changed according to the system setting or the operating environment of the present system, the predetermined time for determining the tagging validity may be 500 ms.

4 is a diagram for explaining an interrupt for recognizing untagging of a smart terminal for a dual interface NFC tag according to an embodiment of the present invention.

As described above, a combined signal of the first port and the second port is used as an interrupt signal for the control unit 310 of the door lock 120 . The first port may be, for example, an EH_FD port as a port for recognizing the tagging of the smart terminal 100 for the dual interface NFC tag 200, and the second port is a dual interface NFC tag from the smart terminal 150a ( 200) as a port for recognizing a record, for example, may be an RF_WIP port.

As shown in FIG. 4, when the combined signal of the first port and the second port is toggle-down from High to Low and a predetermined time for event end determination elapses , the control unit 310 recognizes as untagging of the smart terminal 150a for the dual interface NFC tag 200 .

The reason for introducing the predetermined time for determining the end of the event is that, after the signal waveform is toggled-up due to the tagging of the smart terminal 150a, toggle-down may occur due to various causes. to be. For example, the signal of the first port may be toggled down due to a temporary increase in the contact distance of the smart terminal 150a, and even when the smart terminal 150a performs writing to the memory 220, toggle-down This may happen. Accordingly, the present invention introduces a predetermined time for event end determination to detect only valid untagging. Although it may be changed according to the system setting or the operating environment of the present system, the predetermined time for determining the end of the event may be 100 ms.

5 is a diagram for explaining an interrupt for recognizing a write operation of a smart terminal for a dual interface NFC tag according to an embodiment of the present invention.

As described above, a combined signal of the first port and the second port is used as an interrupt signal for the control unit 310 of the door lock 120 .

5, the combined signal of the first port and the second port is toggled from high to low and then from low to high again within a predetermined time period. When toggled to (high), the control unit 310 recognizes the write operation of the smart terminal 100 to the memory 220 of the dual interface NFC tag 200 .

The predetermined time period may be a predetermined value and may correspond to the toggle-down maintenance that occurs when the smart terminal 150a writes to the memory 220 . Although it may be changed according to the system setting or the operating environment of the present system, the predetermined time period for recognizing the recording operation of the smart terminal 150a may be a time period exceeding 7 ms and less than 10 ms.

Further, as shown in FIG. 5 , when the combined signal of the first port and the second port is toggled from high to low and then toggled from low to high again within a threshold time, the control unit 310 is invalid. action can be recognized. For example, the smart terminal 100 may temporarily move away or toggle-down may occur due to other noise, and if the period is within a threshold time, the control unit 310 does not recognize this phenomenon as a meaningful operation and an invalid operation recognize as It may be changed according to system settings or the operating environment of the present system, but the threshold time for invalid operation recognition may be 7 ms.

9A is a flowchart illustrating an operation method for managing a locker for a public facility for fingerprint recognition according to an embodiment of the present invention.

Referring to Figure 9a, the locker management system 100 for public use according to an embodiment of the present invention, the owner key (150c) provided so that other keys can be registered in all the door locks 120 for a plurality of lockers (110) is registered (S910).

The owner key 150c is registered in all the door locks 120, and functions to register or change other keys, such as the master key 150b, the cleaning keys 150d and CLNK, and the user key 150d.

When the owner key 150c is first registered, the manager combines the owner key 150c with each door lock 120 to read and store information on the owner key 150c from each door lock 120 . Here, it is preferable that there is only one owner key 150c, and since all keys can be registered with the owner key 150c, it is very important for the manager, for example, the owner, to finally manage and take responsibility for the locker 110. desirable.

In the owner key registration process of registering the owner key for the first time, when the administrator wants to register, the door lock 120 is initialized and operated, and the door lock 120 sets the owner key signal means so that the owner key 150c can be registered. It is determined whether or not the owner key set time has elapsed by allocating it to occur or occur during the owner key set time, which is a time.

If the owner key 150c is coupled before the owner key setting time elapses, the owner key is registered. Here, when the owner key setting time has elapsed, the owner key setting time may be set again. Here, even if the owner key 150c is not coupled within the owner key setting time, the owner key setting time is set again, and this step can be applied only when the first owner key 150c is registered. Here, when the owner key 150c to be registered is brought into contact with the door lock 120 , the owner key completion signal means indicating that the registration has been completed in the door lock 120 can be generated or assigned to be generated. In addition, the owner key signal means is one of the key signal means including the master key signal means and the user key signal means to be described later, and is a means that an administrator or user can recognize and recognize. For example, light, light, sound, text, images and the like, and combinations thereof. In addition, in the present invention, the meaning of 'key signal means' is a concept that includes all of the owner key signal means, the master key signal means and the user key signal means, and the meaning of 'generating' the key signal means means that the user uses light, light, and sound. , means that a human being can recognize using the five senses, such as displaying an image or making a sound on the door lock 120 so as to recognize a character or the like. In addition, the meaning of 'allocating' the key signal means is to store or memorize the key signal means corresponding to each key in each door lock 120 in a distinguishable state without generating a key signal means corresponding to each key. means that The key signal means allocated in this way may be generated in the door lock 120 with light, light, sound, etc., if necessary. For example, the owner key signal means may include, for example, expressing the character 'owner key' as an image, or generating a beep sound at regular intervals as one signal. The key completion signal means including the above-described owner key completion signal means or the master key completion signal means and user key completion signal means to be described later may be expressed or generated in the same way as the key signal means. However, in this case, all of the key completion signal means may be equally expressed or generated.

Next, a plurality of master keys 150b provided to open and close all the door locks 120 are registered in all the door locks (S920).

That is, each door lock 120 generates a master key signal means during the master key setting time, and determines whether the master key setting time has elapsed. Here, for convenience of explanation, it is assumed that three master keys (first master key 150b1, second master key 150b2, and third master key 150b3) are registered. As a result of the determination, the master key setting time does not elapse. Instead, when the master key 150b is coupled to the door lock 120, the master key 150b is registered in the door lock 120, and a master key completion signal means is generated. If the master key 150b is not coupled to the door lock 120 within the set period, it is determined again whether the master key setting time has elapsed. .

This process is continued until the registration number of three master keys 150b is completed. Even if three registrations of the master key 150b are completed, the door lock 120 generates the master key signal means once again until the master key setting time elapses. If no key is combined during this period, the user key signal means is generated during the user key setting time, and it is determined whether the user key setting time has elapsed.

Here, the master key signal means of the first master key 150b, for example, expresses the character of the first master key or bundles the beeps into one to emit a sound at a set interval (for example, about 0.5 seconds). generate The master key signal means of the second master key 150b, for example, expresses the character of the second master key or generates a sound at a constant set interval (for example, about 0.5 seconds) by tying the beep beep into one, or It is possible to distinguish each master key signal means by such a method. That is, even if there are a plurality of master keys 150b, the signal means of each master key may be assigned to be expressed or expressed in a different sound, character, light, etc. for easy identification or recognition.

Then, when each master key 150b is registered, each master key completion signal means is assigned to be generated or generated, and the following process is performed.

Next, the user's fingerprint 150d is contacted and registered with one of the plurality of door locks (S930).

At this time, when the user key setting time has elapsed, the user key setting time is set again, and in this case, it is preferable to apply in the process of registering the user key 150d for the first time. When the user's fingerprint 150d as the user key is coupled to the door lock 120 before the user key setting time elapses, the coupled user's fingerprint 150d is registered as the user key 150d, and the user that the user key is registered Generates key completion signaling means.

Here, the user key signal means of the user key 150d can generate or generate a sound at a constant set interval (eg, about 0.5 seconds) by expressing, for example, the character of the user key or tying the beeps into one. can be assigned.

Next, in the state in which the user's fingerprint 150d, master key 150b, and owner key 150c are registered in the door lock 120 through the above-described process, the general user uses the locker 110 assigned to him/herself. For this purpose, the user's fingerprint 150d is brought into contact with the corresponding door lock 120 to open and close the door 130 .

That is, the user brings the user's fingerprint 150d into contact with the fingerprint recognition unit 123 of the door lock 120 , and the door lock 120 in which the fingerprint is registered receives the user's fingerprint 150d through the fingerprint sensor 31 . Detect (S940).

Next, when the user's fingerprint 150d sensed through the fingerprint sensor 31 matches the registered user's fingerprint, the door lock 120 recognizes the user's fingerprint 150d to open the door 130 or The lock is executed (S950).

In the above-described embodiment of the present invention, the user uses the locker 110 after registering the user's fingerprint 150d in the door lock 120 in advance, but is not limited thereto.

That is, before the user uses the locker 110 , the door 130 is always in an open (unlocked) state, and the user puts his or her belongings in the locker 110 and enters the fingerprint recognition unit 123 of the door lock 120 . When the user's fingerprint 150d is in contact for a certain period of time (2 to 3 seconds), the user's fingerprint 150d is registered and stored, and the door 130 is locked, and then again the user's fingerprint 150d. is in contact with the fingerprint recognition unit 123 for a certain period of time (2 to 3 seconds), the door 130 may be in an open (unlocked) state.

9B is a diagram illustrating an operation flowchart for explaining a method for managing lockers for public facilities according to an embodiment of the present invention.

Referring to Figure 9b, the locker management system 100 for public use according to an embodiment of the present invention, the owner key (150c) provided to register other keys to all the door locks 120 for the plurality of lockers (110) is registered (S910).

If the owner key 150c is coupled before the owner key setting time elapses, the owner key is registered. Here, when the owner key setting time has elapsed, the owner key setting time may be set again. Even if the owner key 150c is not coupled within the owner key setting time, the owner key setting time is set again, and this step can be applied only when the first owner key 150c is registered.

When the owner key 150c to be registered is brought into contact with the door lock 120 , the owner key completion signal means indicating that the registration has been completed in the door lock 120 can be generated or assigned to be generated. The key signal means allocated in this way may be generated in the door lock 120 with light, light, sound, etc., if necessary. For example, the owner key signal means may include, for example, expressing the character 'owner key' as an image, or generating a beep sound at regular intervals as one signal.

The key completion signal means including the above-described owner key completion signal means or the master key completion signal means and user key completion signal means to be described later may be expressed or generated in the same way as the key signal means. However, in this case, all of the key completion signal means may be equally expressed or generated.

Next, a plurality of master keys 150b provided to open and close all the door locks 120 are registered in all the door locks (S920).

That is, each door lock 120 generates a master key signal means during the master key setting time, and determines whether the master key setting time has elapsed. Here, for convenience of explanation, it is assumed that three master keys (first master key 150b1, second master key 150b2, and third master key 150b3) are registered. As a result of the determination, the master key setting time does not elapse. Instead, when the master key 150b is coupled to the door lock 120, the master key 150b is registered in the door lock 120, and a master key completion signal means is generated. If the master key 150b is not coupled to the door lock 120 within the set period, it is determined again whether the master key setting time has elapsed. .

This process is continued until the registration number of three master keys 150b is completed. Even if three registrations of the master key 150b are completed, the door lock 120 generates the master key signal means once again until the master key setting time elapses. If no key is combined during this period, the user key signal means is generated during the user key setting time, and it is determined whether the user key setting time has elapsed. Here, when each master key 150b is registered, each master key completion signal means is assigned to be generated or generated, and the following process is performed.

Next, the smart terminal 150a corresponding to one of the plurality of door locks is registered in the corresponding door lock 120 (S960).

At this time, when the user key setting time has elapsed, the user key setting time is set again, and in this case, it is preferable to apply in the process of registering the user key 150a for the first time. When the smart terminal 150a is coupled to the door lock 120 as the user key before the user key setting time elapses, the coupled smart terminal 150a is registered as the user key 150a, and the user key completion signal indicating that the user key is registered create means.

Here, the master key signal means of the first master key 150b, for example, expresses the character of the first master key or bundles the beeps into one to emit a sound at a set interval (for example, about 0.5 seconds). or, the master key signal means of the second master key 150b expresses, for example, the character of the second master key or binds beep beeps into one to make a sound at a constant set interval (for example, about 0.5 seconds). It is possible to distinguish each master key signal means by generating or the like. That is, even if there are a plurality of master keys 150b, the signal means of each master key may be assigned to be expressed or expressed in a different sound, character, light, etc. for easy identification or recognition. The user key signal means of the user key 150a, for example, expresses the character of the user key or binds the beeps into one to generate or generate a sound at a set interval (eg, about 0.5 seconds). can do it

Next, in the state in which the smart terminal 150a, the master key 150b, and the owner key 150c are registered in the door lock 120 through the above-described process, the general user uses the locker 110 assigned to him/herself. , the smart terminal 150a approaches the door lock 120 to perform tagging on the dual interface NFC tag 200 connected to the door lock 120 .

The dual interface NFC tag 200 connected to the door lock 120 corresponding to the smart terminal 150a transmits an opening/closing signal according to tagging to the corresponding door lock 120 through short-range wireless communication with the smart terminal 150a. (S970).

That is, by the tagging of the smart terminal 150a, as shown in FIG. 5, the combined signal of the first port and the second port is toggled from high to low (toggle-down) and When it is toggled-up from low to high again within a predetermined time period, the control unit 310 controls the smart terminal for the memory 220 of the dual interface NFC tag 200 ( 100) to recognize the open/close recording operation.

Then, the corresponding door lock 120 opens or locks the door according to the open/close signal received from the connected dual interface NFC tag 200 (S980).

That is, in the door lock 120, the control unit 310 reads the open/close signal recorded in the memory 220 by the tagging of the smart terminal 150a from the connected dual interface NFC tag 200, and a preset smart terminal 150a ), the opening/closing operation is executed through the opening/closing operation unit 320 in the same case as the opening/closing signal.

On the other hand, the cleaning key 150e functions to open the door lock 120 when the user in possession combines the cleaning key 150e with the door lock 120 for cleaning the locker 110 . It is preferable that the cleaning key 150d is automatically set or recognized as the cleaning key 150d, and the last registered master key 150b among a plurality of registered master keys 150b is automatically set or recognized as the cleaning key 150d, without separately registering the cleaning key 150d. 150b) is deleted. For example, if there were four master keys 150b and the fourth master key 150b is deleted, the third master key 150b, which is the last among the three, is automatically recognized as the cleaning key 150e, so the administrator can It should be noted in the case of deletion of the master key 150b. Therefore, the registration and change of the cleaning key 150e (if the change is registered, the previously registered information is deleted) is performed with the owner key 150c in the same manner as the normal master key 150b.
