1 is a block diagram illustrating a door opening and closing system 100 according to an embodiment of the present invention. The door opening and closing system 100 according to an embodiment of the present invention is a system for opening a locked door through wireless communication with a terminal when a user with a terminal approaches. As shown, the door opening and closing system 100 according to an embodiment of the present invention includes a door lock device 102 and a terminal 104 .

The door lock device 102 is a device attached to the door 106 to lock or unlock the door 106 . In one embodiment, the door lock device 102 may be communicatively connected to the terminal 104 through a wireless communication means (not shown). In embodiments of the present invention, the wireless communication means, for example, Bluetooth (Bluetooth), Wi-Fi (WiFi), Zigbee (Zigbee), WLAN (Wireless Local Area Network), UWB (Ultra Wide Band), BCC (Body Coupled) Communication), NFC (Near Field Communication), etc. may be used.

The terminal 104 is a device possessed by the user 108 who wants to enter and exit the door 106 . In one embodiment, examples of terminal 104 may be a mobile communication device, such as a smart phone, cell phone, tablet, Personal Digital Assistant (PDA), notebook, or wearable device such as a smart watch, Fitness Tracker, or the like. . The terminal 104 may lock or unlock the door 106 by performing wireless communication with the door lock device 102 .

In an embodiment, the door lock device 102 may detect that the user 108 carrying the terminal 104 approaches the door 106 . When the approach of the user 108 is detected, the door lock device 102 authenticates the terminal 104 through wireless communication with the terminal 104 . In addition, the door lock device 102 may measure the position of the authenticated terminal 104 and release the lock state of the door 106 when the terminal 104 is located in a preset area. For example, the door lock device 102 determines whether the terminal 104 (and the user 108 carrying the terminal 104) is indoors or outdoors based on the door 106, and It may be configured to unlock the locked state of the door 106 only when it is determined that it is in the

Figure 2 is a block diagram for explaining the detailed configuration of the door lock device 102 according to an embodiment of the present invention. As shown, the door lock device 102 according to an embodiment of the present invention includes an approach detection module 202 , an authentication module 204 , a position measurement module 206 and a door opening and closing module 208 .

The approach detection module 202 detects the approach of the door 106 of the user 108 carrying the terminal 104 . In an embodiment, the approach detection module 202 may determine whether an object is detected in the vicinity of the door 106 through an infrared sensor, an ultrasonic sensor, or the like. In another embodiment, the approach detection module 202 may include a touch sensor or the like, so that an object is detected through whether the door lock device 102 is touched (ie, whether someone has touched the door lock device 102 ). You can also check whether it is detected or not. However, the present invention is not limited thereto, and the approach detection module 202 may check whether an object is detected through various methods other than those disclosed herein.

The authentication module 204 authenticates the terminal 104 possessed by the user 108 when the approach of the user 108 is detected by the access detection module 202 . In an embodiment, the authentication module 204 may initiate an authentication procedure by sending an authentication request to the terminal 104 . Since the authentication module 204 does not know which terminal 104 is present in the vicinity, it can broadcast the authentication request so that all terminals within the communication range can recognize the authentication request. Then, the terminal 104 receiving this may transmit an authentication response corresponding to the authentication request to the authentication module 204 . Meanwhile, the authentication module 204 may determine that authentication of the terminal 104 has failed when an authentication response is not received within a preset time after transmitting the authentication request. For example, if the object detected by the access detection module 202 is not a person or a person does not possess the terminal 104, even if the authentication module 204 transmits an authentication request, an authentication response is not received. .

When the authentication response is received, the authentication module 204 then authenticates the terminal 104 using information or the like in the authentication response. In an embodiment, when an authentication response is received within a preset time after transmitting the authentication request, the authentication module 204 compares authentication information included in the received authentication response with pre-stored authentication information to check whether authentication succeeds. can In this case, when the received authentication information and the previously stored authentication information are the same, the authentication module 204 may determine that authentication is successful.

In one embodiment, communication between the terminal 104 and the authentication module 204 including the authentication request and authentication response may be made through the aforementioned wireless communication means. For example, the terminal 104 and the authentication module 204 may exchange information for authentication through Bluetooth communication.

In addition, the above-described authentication procedure is merely exemplary, and in the embodiments of the present invention, the authentication module 204 may perform authentication of the terminal 104 through various methods other than those described above.

Next, the position measurement module 206 measures the position of the terminal 104 by detecting the vibration generated by the authenticated terminal 104 .

Specifically, the position measurement module 206 transmits a vibration generation request signal to the authenticated terminal 104 . In this case, the position measurement module 206 may transmit the vibration generation request signal using the same wireless communication means as the wireless communication means used in the authentication of the terminal 104 in the authentication module 204 . For example, when the authentication module 204 authenticates the terminal 104 using Bluetooth, the location measurement module 206 may also transmit a vibration generation request signal to the terminal 104 using Bluetooth. In the case of this configuration, it is efficient to use the previously established wireless communication channel as it is for authentication without the need to set up a wireless communication channel separately from the terminal 104 .

In an embodiment, the vibration generation request signal may simply include a request for activating the vibration function of the terminal 104 for a preset time (eg, 3 seconds). In this case, the terminal 104 receiving the vibration generation request signal generates vibration by turning on the vibration function of the terminal 104 for the requested period. In another embodiment, the vibration generation request signal may include a vibration generation pattern. For example, the vibration generation pattern may be configured to repeatedly turn on/off the vibration of the terminal 104 in a form similar to a pulse or Morse code. In this case, each on or off interval included in the vibration generating pattern may be set differently. When the vibration generation pattern is transmitted to the terminal 104 in this way, the terminal 104 generates vibration according to the received vibration generation pattern.

When vibration is generated in the terminal 104 according to the vibration generation request signal, the position measurement module 206 measures the position of the terminal 104 by detecting the vibration. In one embodiment, the position measurement module 206 uses a wireless communication means (second wireless communication) that is distinct from the wireless communication (first wireless communication) used to transmit the vibration generation request signal to the location of the vibration will detect Specifically, (the position measurement module 206 may detect a vibration generating position using ultra wide band (UWB) wireless communication).

UWB communication is a wireless communication technology that transmits a large amount of information with low power over a very wide band compared to the existing spectrum. In general, in the case of short-distance wireless communication such as Bluetooth, since the object transmittance is low due to the characteristics of radio waves, if the user 108 puts the terminal 104 in a back pocket of pants or a bag, the communication sensitivity is abruptly lowered. In addition, in the case of increasing the reception sensitivity of the door lock device 102 in consideration of this, on the contrary, even when the user is not near the door lock device 102, the terminal 104 is detected and the door 106 is opened. do. In contrast, in the case of UWB communication, since radio waves pass through the body, the user 108 can measure the position no matter where the user 108 puts the terminal 104. It has the advantage of being able to accurately determine whether it is located in front or not.

Specifically, the position measurement module 206 transmits a UWB vibration scan signal to a preset area, and detects the UWB vibration scan signal that is modulated and transmitted by the vibration of the terminal 104 to measure the location of the vibration. In this case, the area is an area for determining whether the user 108 intends to enter the door 106 , and may be, for example, a predetermined area around the entrance including the door 106 . For example, when the door lock device 104 is provided in the front door of the house, the area may be set within a specific distance from the front door.

According to an embodiment, when the vibration generation request signal includes a vibration generation pattern, the position measurement module 206 determines whether the pattern of the sensed vibration and the vibration generation pattern included in the vibration generation request signal are identical, and only if they are the same The position of the terminal 104 that generated the vibration may be measured. When configured in this way, it is possible to prevent the position measurement module 206 from malfunctioning due to vibration (such as vibration generated when receiving a text or phone call) generated by other terminals located in the vicinity of the door lock device 102, By changing the vibration pattern each time and transmitting it to the terminal 104, the security of the door lock device 102 can be further strengthened.

When the position measurement module 206 determines that the position of the terminal 104 is within a preset area, the door opening/closing module 208 unlocks the door 106 so that the user 108 opens the door 106. allow it to pass

In step 306, the terminal 104 receiving the authentication request transmits an authentication response to the authentication request to the door lock device 102, and the authentication module 204 authenticates the terminal 104 using the authentication response do.

In step 308 , the position measurement module 206 of the door lock device 102 transmits a vibration generation request signal to the authenticated terminal 104 . As described above, the vibration generation request signal may include a vibration generation pattern in the vibration generation request signal.

In step 310, the terminal 104 receiving the vibration generating signal generates vibration.

In step 312, the position measurement module 206 sends a UWB vibration scan signal to the set area. Step 312 is performed together while step 310 is performed.

In step 314 , the position measuring module 206 detects the vibration of the terminal 104 according to the UWB vibration scan signal that is modulated and transmitted by the vibration of the terminal 104 , and measures the position of the point where the vibration is generated.
