In addition, the same reference numerals are used throughout the drawings for parts having similar functions and functions.

In addition, throughout the specification, when a part is 'connected' with another part, it is not only 'directly connected' but also 'indirectly connected' with another element interposed therebetween. include In addition, 'including' a certain component means that other components may be further included, rather than excluding other components, unless otherwise stated. In addition, terms such as "...unit" and "module" described in the specification mean a unit that processes at least one function or operation, which may be implemented as hardware or software, or a combination of hardware and software. .

Throughout the specification, "Bluetooth Low Energy (hereinafter referred to as 'BLE') is one of the short-distance communication technologies and refers to the core function of Bluetooth V 4.0. BLE has a relatively small duty cycle compared to the classic Bluetooth standard. It can be produced at a low cost, and has reduced average power and standby power, allowing it to run for years on a coin-sized battery.

1 is a schematic diagram illustrating an operation principle of a BLE service according to an embodiment of the present invention.

Referring to FIG. 1 , a BLE service according to an embodiment of the present invention may be provided using a beacon 100 , a user terminal 1 , and a service server 200 .

Hereinafter, an operation principle of the BLE service according to an embodiment of the present invention will be described with reference to FIG. 1 .

The beacon 100 may provide an infrastructure signal to the user terminal 1 located within a predetermined area, and the user terminal 1 receiving the infrastructure signal communicates with the service server 200 to recognize objects and situations ( Various types of BLE services such as Object & Context Awareness), contents push, indoor positioning, automatic check-in, and geofencing can be provided.

Specifically, the beacons 100 may broadcast an infrastructure signal including their identification information to the outside for BLE communication connection with the user terminal 1 . Here, the beacon 100 may broadcast an infrastructure signal in the form of an advertising packet, and the identification information of each beacon 100 is included in a universally unique identifier (UUID) field or a manufacturer specific data (MSD) field of the advertising packet. can The beacon 100 may broadcast an infrastructure signal at regular intervals or, when a specific event occurs, may broadcast the infrastructure signal in an event-triggered manner.

The user terminal 1 may be a terminal that provides the BLE service to the user through BLE communication with the beacon 100 . Here, the user terminal 1 may be implemented in various forms, for example, a mobile phone, a smart phone, a notebook computer, a tablet PC, an e-book terminal, a digital broadcasting terminal, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia) Player), navigation, etc. may correspond to the user terminal 1 .

Specifically, the user terminal 1 that has received the infrastructure signal from the beacon 100 may transmit the received infrastructure signal to a corresponding service server 200, etc., and the service server 200 responds to the received infrastructure signal. A corresponding BLE service may be provided to the user terminal 1 . For example, when a user enters a specific store while carrying a smartphone, the beacon 100 provided in the store may transmit an infrastructure signal to the user terminal 1 . Thereafter, the user terminal 1 receiving the infrastructure signal may extract the identification information of the beacon 100 from the infrastructure signal and transmit it to the service server 200, and the service server 200 responds to the received identification information Thus, it is possible to transmit product information, sale information, coupons, etc. provided by the store to the user terminal 1 . Accordingly, the user can receive product information or sale information provided by the store through BLE communication just by entering a specific store.

Here, each of the beacons 100 transmits only a small amount of packets such as identification information and signal transmission strength (Tx Power) as an infrastructure signal, and may have low power characteristics that can be operated with a 3V coin-type battery or the like. Accordingly, the beacon 100 may be implemented in a small size, and a separate wired connection is not required in terms of providing short-range wireless communication. In addition, in the case of the beacon 100, it is very easy to install to the extent that an attachable installation using a sticker or the like is possible. However, as it is easy to install, it is not difficult to arbitrarily separate the beacon 100 from the installation position, so the probability of theft of the beacon 100 is very high in the prior art. In particular, in the prior art, even when the theft of the beacon 100 occurred, there was no way to confirm it, so it was very difficult to take measures against the theft.

However, by utilizing the beacon and the beacon theft detection method according to an embodiment of the present invention, it is possible to easily detect whether the beacon has been stolen and to prevent an inducement for theft.

Specifically, the beacon 100 according to an embodiment of the present invention may operate according to a preset operation mode, and the operation mode may include three operation modes such as a movement mode, a normal mode, and a theft mode.

First, the movement mode may be an operation mode in which the BLE service is not provided before the beacon 100 is installed at a preset location. Therefore, in the mobile mode, the beacon 100 may not transmit and receive the infrastructure signal, and the infrastructure signal may not be stored in the storage unit of the beacon 100 . Even if the infrastructure signal is stored in the storage unit of the beacon 100, the mobile mode may not switch to the theft mode regardless of the number of stored infrastructure signals. That is, the movement mode may be an operation mode set in the beacon 100 when the beacon 100 is first installed, or when maintenance or repair is performed. Therefore, if the location of the beacon 100 is changed after the operation mode of the beacon 100 is set to the mobile mode by the manager's operation, the beacon 100 may not perform the determination of whether the beacon 100 is stolen.

The normal mode may be an operation mode in which the beacon 100 is installed at a preset location, and the BLE service is provided to the user terminal 1 and the like. That is, the beacon 100 moved through the movement mode may be installed by an administrator or the like, and the administrator may change the operation mode of the beacon 100 from the movement mode to the normal mode. In the normal mode, the beacon 100 may transmit an infrastructure signal within a predetermined area to provide a BLE service, and additionally receive infrastructure signals transmitted by other beacons located nearby. In particular, when switching from the mobile mode to the normal mode, the beacon 100 may register the received infrastructure signals of nearby beacons and set it as a registration infrastructure signal, and then when a new infrastructure signal other than the registration infrastructure signal is received, You can save this. According to an embodiment, when switching from the mobile mode to the normal mode, it is also possible to initialize the storage unit of the beacon.

The theft mode corresponds to an operation mode when it is determined that the beacon 100 corresponds to a stolen state. The beacon 100 is generally mounted at a fixed position, and the number of infrastructure signals received by the beacon 100 is kept constant unless other beacons are additionally installed around the beacon 100 . Accordingly, if the number of new infrastructure signals in the beacon 100 operating in the normal mode increases by more than a preset limit number, it may be determined that the beacon 100 is moving. In a normal case, since the location of the beacon 100 is changed after the manager switches the operation mode of the beacon 100 to the mobile mode, the location of the beacon 100 operating in the normal mode is not suddenly changed. Therefore, if the location of the beacon 100 operating in the normal mode is suddenly changed, it can be determined that the beacon 100 has been stolen. In this case, the operation mode of the beacon 200 may be switched to the theft mode, and the beacon 100 switched to the theft mode may stop transmitting the infrastructure signal for providing the BLE service, instead of the surrounding beacon An emergency signal informing them that the beacon 100 is currently in a stolen state may be transmitted. In addition, according to an embodiment, the beacon 100 may sequentially store the infrastructure signals of other beacons received after switching to the theft mode. Accordingly, when the beacon 100 is recovered later, it is possible to collect information on the movement path of the stolen beacon 100 using the stored infrastructure signals. Additionally, depending on the embodiment, if it corresponds to theft mode, it is possible to delete or encrypt all information stored inside the beacon 100, and the beacon 100 completely stops the operation or requires a password for the operation. By doing so, it is also possible to block the source of the theft inducement for the beacon 100.

Referring to FIG. 2 , a beacon 100 according to an embodiment of the present invention may include a wireless communication unit 110 , a storage unit 120 , and a control unit 130 . Hereinafter, the beacon 100 according to an embodiment of the present invention will be described with reference to each configuration.

The wireless communication unit 110 may perform transmission of infrastructure signals for BLE communication and reception of infrastructure signals transmitted by other beacons in the normal mode, and stops the transmission of the infrastructure signals and transmits emergency signals in theft mode. can send In addition, the wireless communication unit 110 may stop the transmission and reception of the infrastructure signal in the mobile mode. Here, the control of the wireless communication unit 110 according to each operation mode may be performed by the control unit 130 .

The storage unit 120 may store infrastructure signals of other beacons received by the wireless communication unit 110 . Here, the storage unit 120 may store the infrastructure signals of other beacons received by the wireless communication unit 110 in the normal mode, and may stop the storage of the infrastructure signals in the theft mode or the mobile mode. Meanwhile, the storage unit 120 may select whether to store the received infrastructure signal according to identification information of each beacon included in the infrastructure signal. Specifically, the storage unit 120 may distinguish each infrastructure signal for each beacon by using the identification information included in the infrastructure signal, and may not overlap the infrastructure signal having the same identification information. That is, the storage unit 120 may selectively store only infrastructure signals that are different from identification information of other infrastructure signals in which identification information is already stored, among the received infrastructure signals. Accordingly, all of the infrastructure signals stored in the storage unit 120 may correspond to infrastructure signals received from different beacons. On the other hand, the storage unit 120 may be a storage medium in the form of a stack for sequentially storing the received infrastructure signals, according to an embodiment, the storage unit 120 according to the control of the infrastructure signal under the control of the controller 130. may be to store That is, after the control unit 130 extracts identification information from the received infrastructure signal, the extracted identification information is compared with identification information of the stored infrastructure signals to determine whether to store it, and the storage unit 120 is simply the control unit 130 ) may be performing a function of storing the received infrastructure signal according to the command.

The control unit 130 may determine whether the beacon is stolen according to the number of infrastructure signals stored in the storage unit 120 . For example, if the number of infrastructure signals stored in the storage unit 120 is greater than or equal to a preset limit, the beacon may be determined to be stolen, and the control unit 130 may change the operation mode of the beacon to the theft mode. can In general, the beacon 100 is mounted at a fixed position, and unless other beacons are additionally installed around the beacon 100, the number of infrastructure signals of other beacons received by the beacon 100 will be kept constant. can Accordingly, the control unit 130 sets the infrastructure signals of other beacons stored in the storage unit 120 as the registration infrastructure signals when switching from the movement mode to the normal mode, and sets the number of registered infrastructure signals to the limit number. can be set. However, depending on the embodiment, it is also possible to set the limit number in consideration of the additional mounting of other beacons. For example, when the number of registration infrastructure signals is 10, the limit number may be set to 13.

Depending on the embodiment, it is also possible to switch to theft mode when the capacity of the storage unit 120 is exceeded and the infrastructure signal can no longer be stored. That is, the storage unit 120 may transmit a signal notifying that the storage space is insufficient to the control unit 130, and the control unit 130 receiving the signal converts the operation mode of the beacon 100 from the normal mode to the theft mode. can do. For example, the storage unit 120 may have a capacity to store 10 infrastructure signals, and after all 10 infrastructure signals are stored, storage of additional infrastructure signals may be requested. In this case, the storage unit 120 may transmit a signal notifying that the storage space is insufficient to the control unit 130 , and the control unit 310 may switch the operation mode of the beacon 100 to the theft mode.

Meanwhile, the control unit 130 may perform a function of switching the operation mode of the beacon 100 according to an input of an administrator or the like. That is, by controlling the operations of the wireless communication unit 110 and the storage unit 120 according to the input of the manager, the beacon 100 can be controlled to operate in a mobile mode, a normal mode, and the like.

Additionally, the control unit 130 may sequentially store the infrastructure signals of other beacons received through the wireless communication unit 110 while operating in the theft mode in the storage unit 120 to generate theft movement path information. That is, when the beacon 100 is recovered later, it is possible to collect information on the movement path of the stolen beacon 100 using the infrastructure signals stored in the storage unit 120 .

In addition, while operating in the theft mode, the control unit 130 determines whether or not light above a preset limit illuminance is detected by the illuminance sensor provided inside the beacon 100, and the pressure sensor provided in the beacon 100 determines whether or not light is detected. It is possible to check whether a force greater than the set limit pressure is detected, whether a motion greater than a preset reference value is detected by the motion detection sensor, and the like. That is, in the state in which the beacon 100 is stolen, whether a situation such as movement of the beacon 100 is detected, the inside of the beacon 100 is opened, or pressure is applied to open the beacon 100 occurs Whether or not, the control unit 130 may check through the illuminance sensor, pressure sensor, motion detection sensor, and the like. If the beacon 100 moves above the reference value, light above the preset threshold illuminance is detected, or a force above the threshold pressure is detected, the control unit 130 deletes all information stored in the beacon 100 or Encryption, the operation of the beacon 100 may be completely stopped or a password may be requested during operation. That is, when the beacon 100 is stolen, by making it impossible to utilize the information stored in the beacon 100 or the beacon 100 itself, it is possible to fundamentally block the inducement for the theft of the beacon 100 .

Meanwhile, the operation of the beacon 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 6 .

First, when the beacon 100 is initially set to the mobile mode, infrastructure signals, etc. may not be stored in the storage unit 120 at all, as shown in FIG. 3 . Here, the storage unit 120 is exaggerated for convenience of description and may be different from the actual one. Thereafter, as shown in FIG. 4 , when the beacon 100 is mounted at a preset position and switched from the movement mode to the normal mode, other beacons 1 , 2 , 3 located in the vicinity of the beacon 100 . Each infrastructure signal can be received from In this case, the beacon 100 may set and store the received infrastructure signal as a registered infrastructure signal.

On the other hand, as shown in FIG. 5 , when the beacon 100 operating in the normal mode moves, the beacon 100 moves from the other beacons 4 , 5 , 6 , and 7 that exist on the movement path of the beacon 100 , respectively. of infrastructure signals can be received. That is, as shown in FIG. 5 , the storage unit 120 of the beacon 100 has a capacity to store six infrastructure signals, but as the beacon 100 moves, it The storage of the seventh infrastructure signal may be requested. In this case, since the beacon 100 is requested to store the infrastructure signal exceeding the preset limit number, that is, six, the beacon 100 may operate in the theft mode. Accordingly, as shown in FIG. 6, the beacon 100 transmits an emergency signal to other nearby beacons (a, b, c, d, e), etc. instead of an infrastructure signal, so that the beacon 100 is currently stolen. status can be indicated. According to an embodiment, other beacons (a, b, c, d, e) that have received the emergency signal from the beacon 100 may transmit the received emergency signal to the management server 300 . Therefore, the management server 300 can determine the movement path of the stolen beacon 100 by using the time-series sequence of the collected emergency signals, and based on this, collect the stolen beacon 100, etc. action can be taken for Here, the management server 300 may be implemented using the service server 200 .

7 is a flowchart illustrating a method for detecting theft of a beacon according to an embodiment of the present invention.

7, the beacon theft detection method according to an embodiment of the present invention includes a normal mode conversion step (S100), a normal mode step (S200), an infrastructure signal collection step (S300), a theft mode step (S410, S420) and data disposal step (S500).

Hereinafter, a beacon theft detection method according to an embodiment of the present invention will be described with reference to FIG. 7 .

Initially, the beacon may be in a movement mode in which transmission, reception, and storage of infrastructure signals are stopped. can When the beacon is switched from the mobile mode to the normal mode, infrastructure signals of other beacons received by the beacon may be set as registered infrastructure signals, and a limit number may be set using the number of registered infrastructure signals.

In the normal mode step ( S200 ), the beacon may operate in a normal mode in which the beacon transmits an infrastructure signal for BLE communication with the user terminal and receives the infrastructure signals transmitted by other beacons.

In the infrastructure signal collection step (S300), the beacon may store the received infrastructure signals of other beacons. That is, while the beacon operates in the normal mode, infrastructure signals transmitted by other beacons may be received, and the received infrastructure signals may be stored separately according to each identification information. In particular, infrastructure signals including the same identification information may not be repeatedly stored.

In the theft mode step (S410, S420), first, the number of stored infrastructure signals of other beacons may be compared with a preset limit number (S410), and if the number of stored infrastructure signals of other beacons is greater than or equal to the preset limit number, , the beacon may stop transmitting the infrastructure signal and operate in a theft mode in which an emergency signal is transmitted (S420). When operating in the theft mode, the beacon may sequentially store the infrastructure signals of other beacons received in the theft mode to generate theft movement path information (S420). That is, when the stolen beacon is recovered thereafter, information on the path the beacon has moved may be extracted by utilizing the stolen movement path information stored in the beacon.

In the data disposal step (S500), all information stored in the beacon may be deleted or encrypted. Specifically, in the theft mode, when light above the preset limit illuminance is detected by the illuminance sensor provided inside the beacon or a force greater than the preset limit pressure is detected by the pressure sensor provided inside the beacon, the information stored in the beacon is stored. All can be deleted or encrypted. That is, by disabling the use of stolen beacons, it is possible to fundamentally block the incentive to theft of beacons.
