Description

  Embodiments described herein relate generally to a technique for determining a user's current location using a beacon and a wireless access point and providing a location information service based on the user's current location.

  The wireless positioning service is a technique for measuring a user's position in order to provide a location information service (LBS: Location-Based Services) based on the current position of the user. The location information service provides services such as an indoor map based on the location of a smartphone, PDA, tablet PC, or the like located inside a building using GPS, Wi-Fi, or the like.

  However, in the case of GPS or Wi-Fi, there is a large error with respect to the position of the terminal measured inside the building, and it is difficult to provide an appropriate position information service.

  As an example, when a user is located in an elevator or an escalator used for moving between floors in a building, the position of the user is erroneously displayed on an indoor map. In the case of an elevator, there is no wall between the floors, and the entire floor is blown as a single passage, so that the Wi-Fi signal is transmitted over the entire floor. Accordingly, when the user moves from the second floor to the fifth floor and then gets off the elevator, the second floor is displayed even though the user's position is the fifth floor. In addition to this, even if the user does not move by the elevator but is located near the elevator on the fifth floor, the user's position is displayed so as to be completely different, such as the second floor or the third floor.

  As described above, the position of the user is erroneously determined by the characteristic that the Wi-Fi signal is transmitted through the floor, and as a result, the position information service corresponding to the incorrect position is provided to the user. The problem arises. For example, the user is located in a store near the elevator on the 5th floor, but the location information service corresponding to the wrong location such as an indoor map on the 2nd floor or a point of interest (POI) on the 2nd floor is provided to the user Is done.

  Therefore, even when the user moves between floors or is located in the vicinity of means for providing movement between floors (for example, elevators, escalators, etc.), the position information service is provided by accurately measuring the position of the user. There is a need for technology to provide

  The present invention makes it possible to measure a user's position more accurately by using a beacon signal in a space where it is difficult to connect to a Wi-Fi signal or where a positioning error is large such as an escalator or an elevator.

  FIG. 1 shows a wireless positioning service system 100, a plurality of beacon transmitters 101, a plurality of wireless access points (AP) 102, and a user terminal 103. In this embodiment, the beacon transmitter and the wireless access point are described separately. However, the beacon transmitter is one of the wireless access points, and transmits and receives beacon signals based on the Bluetooth standard. The wireless access point may mean a device that transmits and receives a Wi-Fi signal based on the Wi-Fi communication standard. In addition to beacon signals and Wi-Fi signals, a variety of different types of signals that provide short-range wireless communication may be mixed to provide a wireless positioning service.

  The plurality of beacon transmitters 101 are devices that transmit and receive beacon signals using a Bluetooth module (short-range wireless communication module) attached to the user terminal 103, and wireless access point signals such as Wi-Fi signals are transmitted inside the building. It may be installed in advance in a specific place that travels between floors. For example, a plurality of beacon transmitters 101 may be arranged in advance on a ceiling around a floor where an elevator for each floor is located, and at least one of the plurality of beacon transmitters 101 may be mounted on a wireless access point. Good.

  The plurality of wireless access points 102 may be arranged in a store inside the building, a passage ceiling inside the building, or the like. In addition, at least one of the plurality of wireless access points 102 may be arranged around the beacon transmitter 101, and at least one wireless access point may be equipped with a beacon transmitter. For example, the wireless access point and the beacon transmitter may be manufactured integrally, or the beacon transmitter may be detached from the wireless access point.

  The user terminal 103 may receive a wireless access point signal and a beacon signal from the wireless access point 102 and the beacon transmitter 101 arranged inside the building while moving inside the building.

You may receive a beacon signal from a beacon transmitter when it is located around the floor moving means or moves between floors. In addition, when a Wi-Fi transmitter exists in the vicinity of the beacon transmitter, the user terminal 103 may receive all of the beacon signal and the Wi-Fi signal. For example, when a Wi-Fi transmitter is present within a reference radius set in advance with a beacon transmitter as a reference, and when a Wi-Fi transmitter is equipped with a beacon transmitter, the user terminal 103 is: You may receive all a beacon signal and a Wi-Fi signal.

  The wireless positioning service system 100 may provide a user with a wireless positioning service based on a beacon signal or a Wi-Fi signal. For example, the wireless positioning service system 100 receives a beacon signal or a Wi-Fi signal collected by the user terminal 103 from the user terminal 103 by executing a corresponding application in order to receive provision of the location information service at the user terminal 103. The user's current location is determined based on the received beacon signal or Wi-Fi signal, and location information services such as an indoor map inside the building, route guidance, and event information are provided to the user terminal 103 based on the determined current location. May be.

  In addition, as the user terminal 103, a smartphone, a tablet PC, or the like may be used, and a location information service is provided by connecting a web / mobile site related to the location information service or installing and executing a service-dedicated application. Also good. At this time, the user terminal 103 may execute general service operations such as service screen configuration, data input, data transmission / reception, and data storage under the control of a web / mobile site or a dedicated application.

  FIG. 2 is a diagram illustrating a beacon transmitter and a wireless access point arranged inside a building according to an embodiment of the present invention.

  Wireless access points may be placed at regular intervals in the passages inside the building and in each store inside the building, and beacon transmitters are placed around the building's underground parking lots, elevators, escalators, etc. Also good. In order to provide wireless positioning and location information services in shaded areas (for example, parking lots, elevators, escalators, etc.) where wireless access point signals are arranged more than beacon transmitters and wireless access point signals are difficult to connect It may be arranged.

  Referring to FIG. 2, the beacon transmitter (B) has a location around each level of elevator inside the building (for example, the ceiling of the corresponding floor where the elevator is located), the location where the escalator begins, the location corresponding to the middle of the escalator, and It may be arranged at a place where the escalator ends.

  Taking the escalator that goes up from the first floor to the second floor as an example, the beacon transmitter 1 (the counter, pillar, sales stand etc. on the first floor sales floor around the escalator) 201) and a beacon transmitter 2 (202) is also arranged at an intermediate position of the escalator, such as an advertising signboard, and the peripheral facilities of the second floor escalator where the escalator ends (for example, counters of the second floor sales floor around the escalator The beacon transmitter 3 (203) may be arranged on a pillar, a sales stand, etc.

  Further, at least one wireless access point may be arranged around the beacon transmitter. For example, the wireless access point 1 (204) is arranged around the beacon transmitter 1 (201), and the wireless access point 2 (205) and the wireless access point 3 (206) are arranged around the beacon transmitter 3 (203). The wireless access point 4 (208) may be arranged around the beacon transmitter 4 (207). Further, the beacon transmitter and the wireless access point may be arranged so as to face the floor from the ceiling.

  FIG. 3 is a diagram illustrating a packet structure of a beacon signal according to an embodiment of the present invention.

  In FIG. 3, the packet structure of the beacon signal indicates a broadcast (BroadCast) packet structure with low power consumption. The packet is a 1-byte preamble, a 4-byte access address (Access Address), and 2 It may include a ~ 3 byte protocol data unit (PDU: Protocol Data Unit) and a 3 byte CRC code.

  The protocol data unit may include a 2-byte header, a 6-byte Mac address, and 31 bytes of data. Here, the data may include unique identification information (Major, Minor) given to each beacon signal. Thus, since the identification information is included for each beacon signal, the wireless positioning service system can classify each beacon signal received from a plurality of beacon transmitters, and to which beacon transmitter the received beacon signal is. You can see if it is true.

  FIG. 4 is a block diagram showing an internal configuration of a wireless positioning service system in one embodiment of the present invention, and FIG. 5 is a flowchart showing a wireless positioning service method in one embodiment of the present invention.

  The wireless positioning service system 400 according to the present embodiment may include a processor 410, a bus 420, a network interface 430, and a memory 440. The memory 440 may include an operating system 441 and a radio positioning service provision routine 442. The processor 410 may include an information receiving unit 411, a position determining unit 412, and a service providing unit 413. In other embodiments, the wireless positioning service system 400 may include more components than the components of FIG. For example, the wireless positioning service system 400 may include other components such as a display and a transceiver.

  The memory 440 is a computer-readable recording medium, and may include a RAM (Random Access Memory), a ROM (Read Only Memory), and a permanent mass storage device such as a disk drive. Good. The memory 440 may store program codes for the operating system 441 and the wireless positioning service provision routine 442. Such software components may be loaded from a computer-readable recording medium separate from the memory 440 using a drive mechanism (not shown). Such a separate computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, disk, tape, DVD / CD-ROM drive, memory card, and the like. . In other embodiments, the software components may be loaded into the memory 440 through the network interface 430, which is not a computer readable recording medium.

  Bus 420 may allow communication and data transmission between components of wireless positioning service system 400. The bus 420 may be configured using a high-speed serial bus, a parallel bus, a SAN (Storage Area Network), and / or other suitable communication technology.

  The network interface 430 may be a computer hardware component for connecting the wireless positioning service system 400 to a computer network. The network interface 430 may connect the wireless positioning service system 400 to a computer network via a wireless or wired connection.

  The processor 410 may execute a radio positioning service provision routine stored in the memory 440, determine a user's current position inside a building where the user is located, and provide a location information service based on the current position.

  The processor 410 may be configured to process computer program instructions by performing basic arithmetic, logic, and input / output operations of the wireless positioning service system 400. The instructions may be provided to processor 410 by memory 440 or network interface 430 and via bus 420. The processor 410 may be configured to execute program codes for the information receiving unit 411, the position determining unit 412, and the service providing unit 413, and the program code may be stored in a recording device such as the memory 440. It may be stored.

  The information receiving unit 411, the position determining unit 412, and the service providing unit 413 may be configured to execute Steps 510 to 550 of FIG. In the following, a case will be described in which wireless positioning is provided by mixing wireless access point signals and beacon signals in a state where wireless positioning is provided based on wireless access point signals (for example, Wi-Fi signals).

  In step 510, the information reception unit 411 may receive a wireless access point signal through an application installed in the user terminal 103. At this time, the user terminal 103 may collect wireless access point signals from at least one wireless access point located around the user among a plurality of wireless access points arranged in the building.

  For example, when a user moves through a passage inside a building or is located around an escalator, the user terminal 103 uses a Wi-Fi module to transmit a Wi-Fi transmitted from a Wi-Fi transmitter located around the user. -A Fi signal may be received. The Wi-Fi signal may include a MAC address that is identifier information of the Wi-Fi transmitter.

  In step 520, the position determination unit 412 confirms whether at least one of the signals received from the user terminal 103 includes a signal transmitted from a Wi-Fi transmitter located around the beacon transmitter. May be.

  For example, when building an indoor map of a building in advance, it is possible to know in advance Wi-Fi transmitters located around a beacon transmitter among Wi-Fi transmitters arranged inside the building. That is, the MAC address of the Wi-Fi transmitter located around the beacon transmitter may be constructed in advance. Whether the location determination unit 412 matches the MAC address of the Wi-Fi signal received by the application installed in the user terminal 103 with the MAC address of the Wi-Fi transmitter located around the beacon transmitter stored in advance. May be confirmed.

  In the case of matching (step 520: YES), the position determination unit 412 may perform control so that the operation state of the Bluetooth module of the user terminal 103 is changed to an ON state using an application. Accordingly, the user terminal 103 may collect the beacon signal transmitted from the at least one beacon transmitter by the Bluetooth module, and provide the collected beacon signal to the wireless positioning service system 100 through the application.

  In step 530, the position determination unit 412 may determine the current position of the user based on the beacon signal. For example, the position determination unit 412 may stop the operation of determining the current position of the user based on the Wi-Fi signal and determine the current position of the user based on the beacon signal.

  In step 540, the service providing unit 413 may provide a location information service based on the current location of the user. For example, the service providing unit 413 provides an indoor map such as a route guide based on the current location of the user inside the building, and provides events corresponding to each store inside the building, coupon discount information, and the like according to the user's movement You may do it.

  Referring to step 520 again, if the MAC address of the Wi-Fi signal does not match the MAC address of the Wi-Fi transmitter located around the pre-stored beacon transmitter (step 520: NO), the position determination unit 412 May determine the current location of the user based on the Wi-Fi signal (step 550). The service providing unit 413 may provide a location information service based on the current location of the user.

  For example, when there is no matching, the position determination unit 412 may continue to provide wireless positioning based on the Wi-Fi signal. At this time, the position determination unit 412 confirms the operation state of the Bluetooth module using an application installed in the user terminal 103, and the user terminal is configured so that the operation state of the Bluetooth module is turned off based on the confirmation. 103 may be controlled.

  As an example, when the operation state of the Bluetooth module is on (ON), the position determination unit 412 may change the operation state of the Bluetooth module to an off state using an application. For example, when the user walks on the passage on the second floor after getting on the escalator from the first floor to the second floor, the operation state of the Bluetooth module may be on. Thereafter, when the user moves through the passage on the second floor and there is no beacon transmitter in the vicinity of the user, it is not necessary to maintain the operation state of the Bluetooth module any longer. Accordingly, the position determining unit 412 can reduce battery consumption by changing the operation state of the Bluetooth module to the OFF state.

  As another example, when the operation state of the Bluetooth module is in an OFF state, the position determination unit 412 uses the application so as to maintain the operation state of the Bluetooth module in the user terminal. 103 may be controlled.

  FIG. 6 is a flowchart showing a detailed operation for performing wireless positioning based on a beacon signal in an embodiment of the present invention.

  In FIG. 6, steps 610 to 630 may be executed by the information receiving unit 411, the position determining unit 412, and the service providing unit 413.

  Referring to FIG. 6, the information reception unit 411 may receive a Wi-Fi signal transmitted from a Wi-Fi transmitter located around the beacon transmitter.

  In step 610, the position determination unit 412 may change the operation state of the Bluetooth module to an ON state through an application installed in the user terminal 103.

  The user terminal 103 may collect beacon signals transmitted from the beacon transmitter by the Bluetooth module.

  In step 620, the information receiving unit 411 may receive a beacon signal collected by the user terminal 103 through an application.

  In step 630, the position determination unit 412 uses either the beacon signal or the Wi-Fi signal based on the beacon signal level (for example, signal strength such as RSSI) and a preset reference level. You may decide whether to provide wireless positioning.

  For example, when the level of the received beacon signal is equal to or higher than the reference level (630: YES), the position determination unit 412 stops the Wi-Fi-based positioning that has been used for wireless positioning and is based on the beacon signal. The user's current position may be determined. You may raise the level (RSSI) of the received beacon signal, so that it is located near a beacon transmitter, such as a user being located in the vicinity of an elevator or getting on an elevator. The closer to the elevator, the more difficult the Wi-Fi signal is to be connected due to the inter-level movement characteristics of the Wi-Fi signal, and the error in wireless positioning using the Wi-Fi signal increases. Thereby, when the level of the beacon signal becomes equal to or higher than the reference level, the position determination unit 412 determines the current position of the user more accurately by using the beacon signal instead of the Wi-Fi signal, and the more accurate position Information services can be provided.

  Moreover, when the level of the received beacon signal is lower than the reference level (630: NO), it corresponds to the case where the user moves toward the destination after getting off rather than when the user gets on the elevator or the escalator. There are many. Accordingly, the position determination unit 412 may repeat the process of confirming whether the collected Wi-Fi signal is a signal transmitted from a Wi-Fi transmitter located around the beacon transmitter. The current position of the user may be determined based on the Wi-Fi signal.

  FIG. 7 is a diagram provided to explain an operation of performing wireless positioning based on a beacon signal in an embodiment of the present invention. FIG. 7 is a diagram provided to explain the case where the user moves on the escalator and moves in the up direction. However, the same method is applied to the case where the user moves in the down direction in addition to the up direction. May be.

  Referring to FIG. 7, when a user moves from the wireless access point 1 (701) toward the wireless access point 3 (703), the user moves the wireless access point 1 (701) and the wireless access point 2 (702). ), The user terminal 103 may receive Wi-Fi signals from the wireless access points 1 (701) and 2 (702). The information receiving unit 411 may receive a Wi-Fi signal collected by the user terminal 103 through an application. Accordingly, the location determination unit 412 may determine the current location of the user based on the received Wi-Fi signal, and the service providing unit 413 may provide the location information service based on the determined current location of the user.

  Thereafter, when the user moves from the wireless access point 2 (702) to 3 (703), the user terminal 103 receives the Wi-Fi signal transmitted from the wireless access points 2 (702) and 3 (703). The information receiving unit 411 may be provided through an application. The position determination unit 412 may confirm that the beacon transmitter 1704 is located in the vicinity based on the MAC address of the Wi-Fi signal received from the wireless access point 3 (703). Accordingly, the position determination unit 412 may control the user terminal 103 so as to change the operation state of the Bluetooth module to the on (ON) state. When the Bluetooth module is turned on (ON), the user terminal 103 may receive a beacon signal from the beacon transmitter 1 (704). When the user passes the escalator without getting on the escalator, or passes the sales floor around the escalator and moves away from the beacon transmitter 1 (704), the level of the received beacon signal becomes lower than the reference level. Accordingly, the position determination unit 412 may determine the current position of the user based on the Wi-Fi signal, and may control the user terminal 103 so that the operation state of the Bluetooth module is turned off.

  On the other hand, the level of the beacon signal 1 received from the beacon transmitter 1 (704) is equal to or higher than the reference level, the user terminal 103 collects the beacon signal 2 from the beacon transmitter 2 (705), and the beacon transmitter again. When the beacon signal 3 is received from 3 (706), the position determination unit 412 may determine that the user is moving on the escalator from the first floor to the second floor. For example, the position determination unit 412 may confirm that the signal transmitted from the beacon transmitter 1 arranged around the first floor escalator is received based on the MAC address of the beacon transmitter 1. Based on the same method, the position determination unit 412 receives the signal transmitted from the beacon transmitter 2 arranged on the advertising signboard around the escalator between the first floor and the second floor based on the MAC addresses of the beacon transmitters 2 and 3. You may confirm that it received and the signal transmitted from the beacon transmitter 3 arrange | positioned around the 2nd floor escalator was received. Based on such confirmation, the position determination unit 412 may determine that the user has moved on the escalator and moved upward from the beacon transmitter 1 (704) toward the beacon transmitter 3 (705).

  In addition to the MAC address of the beacon signal, the position determination unit 412 may determine that the user is moving in the upward direction of the escalator based on the signal strength. For example, when the user moves on the escalator from the first floor to the second floor, the strength of the beacon signal 1 received from the beacon transmitter 1 (704) gradually decreases, and the beacon signal 2 received from the beacon transmitter 2 (705). The intensity of the beacon signal 2 is reduced again after the intensity of the beacon is increased, and the intensity of the beacon signal 3 received from the beacon transmitter 3 (706) is increased. As described above, the position determination unit 412 may determine that the user is moving from the first floor to the second floor on the escalator based on the change in strength (RSSI) of the beacon signal.

  At this time, after the user moves on the escalator from the first floor to the second floor, the user may get off the escalator and move toward the second floor destination, and then move to the third or fourth floor. is there. When the user terminal 103 continues to move on the escalator, the user terminal 103 continuously collects beacon signals from beacon transmitters installed around the escalator and provides the information to the information reception unit 411. The position determination unit 412 It may be determined that the user has moved to the third floor, the fourth floor, or the like.

  On the other hand, when the user moves down from the escalator on the second floor, the signal level of the beacon transmitter 3 (706) is higher than the reference level until the time when the user gets off, but the user goes to the destination after getting off. To move away from the beacon transmitter 3 (706). Eventually, when the signal level of the beacon transmitter 3 (706) becomes lower than the reference level and the Wi-Fi signal is received from the wireless access points 4 (707) and 5 (708), the position determination unit 412 The user's current position may be determined based on the Wi-Fi signal received from the wireless access points 4 (707) and 5 (708).

  At this time, after the user gets off the escalator on the second floor, the user may change direction to the left side or the right side and move toward the destination. In this way, when the user changes direction, the gyro sensor mounted on the user terminal 103 may detect the user's change of direction.

  For example, the service providing unit 413 receives the rotation angle detected by the gyro sensor and the step counter by the user's direction change through the application, and determines how much the user has rotated based on the received rotation angle and the step counter. May be. The service providing unit 413 may confirm by the gyro sensor that the user has rotated 30 degrees, 45 degrees, 90 degrees, etc., even if the reference point is not known. As a result, the service providing unit 413 can immediately reflect the change in position due to the user changing the direction to the left side or the right side, or the user changing the direction in a passage or a crossroad inside the building on the indoor map. It becomes like this. For example, the service providing unit 413 may rotate the indoor map based on the direction changed by the user and provide it to the user.

  In FIG. 7, it has been described that the service providing unit 413 provides the user's direction change sensed by the gyro sensor on the indoor map, but in addition, the user terminal 103 displays the user's direction change on the indoor map. You may reflect and display. For example, the user terminal 103 may determine how much the user has rotated based on the rotation angle detected by the gyro sensor and a step counter. The user terminal 103 may rotate and display the indoor map based on the determined rotational movement value. The operation of providing the user's detailed movement path using the gyro sensor will be described with reference to FIG.

  FIG. 8 is an exemplary diagram provided to explain an operation of providing a detailed movement path of a user using a gyro sensor in an embodiment of the present invention.

  There are many structures that affect magnetism, such as sewer pipes and electrical wiring, in rooms such as inside buildings, so the magnetism of east, west, south, and north is all different. When the user's direction (for example, east, west, south, and north) is determined indoors using a compass, the error is extremely large, and a completely different direction is determined as the user direction. Thus, in the present embodiment, an operation using a gyro sensor and a beacon to accurately determine the direction of the user even in the room will be described with reference to FIG. For example, if a gyro sensor is used, it is not possible to know the direction of east, west, south, and north, but it is possible to know how much it has been turned based on the sensing value. Further, the reference point can be known by using a beacon transmitter or a wireless access point. As a result, the wireless positioning service system can confirm that a change of direction such as 90 degrees or 180 degrees has occurred with reference to the reference point.

Thus, when moving to the destination, the wireless positioning service system 400 may provide the user terminal 103 with the detailed movement route 801 of the user reflected in the indoor map using a gyro sensor. Moreover, the direction which changes according to a user's detailed movement may be reflected on an indoor map, and a map may be rotated and provided to a user.

  For example, when the user moves to the left after getting off the escalator, the gyro sensor may immediately detect that a rotational movement has occurred at 90 degrees. At this time, the user terminal 103 collects the Wi-Fi signal from the wireless access point 1 (802) until it senses the rotational movement, and then collects the Wi-Fi signal from the wireless access point 2 (803) while rotating. Then, the information may be provided to the information receiving unit 411. As a result, the service providing unit 413 recognizes that the 90-degree rotational movement has occurred, and moves to the left with reference to the wireless access points 1 (802) and 2 (803) where the rotational movement has occurred. You may decide that That is, the service providing unit 413 may determine that a 90-degree direction change has occurred on the left side. And the service provision part 413 may rotate and provide an indoor map in the direction which the user changed the direction. As described above, by rotating the indoor map according to the direction change of the user and providing the current map from the current position to the destination, it is possible to provide the user with more accurate route guidance.
