Description

TECHNICAL FIELD [0001] The present invention relates to a service system and method for providing indoor location information using a card view,

Embodiments of the present invention relate to a technique for providing indoor location information using a card view and a service system and method for providing information for interlayer movement in providing indoor location information.

Recently, with the spread of smart phones and the development of mobile communication networks, users can freely receive various information and services without restriction of time and space.

Among the services provided by the users, the location based service is applied to the notification of the bus / subway arrival time, navigation, and the like, and provides information suitable for various purposes to the users. In order to provide the location-based service to the user, it is necessary to acquire accurate position information of the user or the object. Such position information is generally acquired based on the GPS (Global Positioning System) signal. However, when acquiring the position information based on the GPS signal, it is difficult to measure the position of the actual user or the object in a region where the GPS signal is difficult to reach, such as the shaded area of the GPS signal or the interior of the building have.

Accordingly, as a method for providing location-based services even in areas where GPS signals are difficult to reach, such as inside buildings, Korean Patent Publication No. 10-2012-0029976 (published on March 27, 2012) A method of collecting reference information for an indoor access point, a method of collecting reference information for indoor access point, a method of collecting reference information for indoor access point, Mapping information on a monitoring access point to an indoor map, generating location information on the indoor map for the virtual access point using scan information for at least one or more virtual access points obtained through the scan information, And a monitoring unit By generating the points, and identification information for the cell, each including the virtual access point collects the reference point information for the indoor wireless positioning discloses a method for measuring the indoor location.

However, this method has a problem that the distance error is large at the positioning, the response speed is slow, and the reliability is low because it is a virtually calculated position rather than the actual collected data.

Therefore, there is a need for a method for measuring the current position of a user more accurately and accurately than a conventional positioning method even in a region where GPS signals are difficult to reach, such as inside a building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present embodiments relate to a service system and a service method capable of providing travel route information in consideration of an interlayer moving means.

1 is a diagram showing an example of a service providing environment in an embodiment of the present invention. Figure 1 shows a service system 100, a user terminal 110 and a target architecture 120.

The service system 100 may be a server device that collects information (e.g., facility-specific information) about the target architecture 120 and provides services related to the target architecture 120 to the user terminal 110. At this time, the target architecture 120 may be a structure associated with a service to be provided to the user terminal 110 among a plurality of structures in which the service system 100 has received relevant information. For example, the target architecture 120 may be a building selected through the user terminal 110 or a building in which the user terminal 110 is located. As another example, the target architecture 120 may include a plurality of architectures connected to each other. For example, when a subway station is connected to a department store, a building for a subway station and a building for a department store can be a target building 120.

The user terminal 110 may be a device of a service user who can access the service system 100 through a wired network and / or a wireless network and receive services.

The service system 100 may collect and maintain facility-specific information located within the target building 120. At this time, the facility-specific information may include information about a company located inside the target building 120 (for example, a shop that has entered a department store or an outlet) and a convenience facility (toilet, elevator, escalator, stairs, etc.) .

In addition, the service system 100 may determine a start position and a destination position. For example, the starting position and the destination position may be selected via the user terminal 110. [ The service system 100 may transmit the map information in the target building 120 to the user terminal 110 and may determine the locations selected by the user terminal 110 based on the map information as the start position and the target position. The starting position may optionally be determined to be the indoor position of the user terminal 110. [

In addition, the service system 100 can generate movement route information from the start position to the destination position using the facility-specific information. The movement route information may be transmitted to the user terminal 110, and the movement route information may be displayed together with the map information in the user terminal 110, thereby providing the mobile route service to the user.

At this time, the service system 100 confirms the information on the inter-layer moving means included on the paths that can be moved from the starting position to the destination position through the facility-specific information, Can be determined. Here, the inter-layer moving means may mean means used for moving to another layer such as, for example, an escalator, an elevator, a stair, or the like. In other words, the service system 100 provides the movement route information, and in the case of the interlayer movement, the movement route information can be generated in consideration of the interlayer movement means.

FIGS. 2 to 5 are diagrams illustrating an example of providing movement route information in an embodiment of the present invention.

In FIGS. 2 to 5, the first screen 200 to the fifth screen 500 illustrate examples of screens displayed on the user terminal 110 in providing movement route information.

The first screen 200 shown in FIG. 2 is an example of a screen of the user terminal 110, and includes a '6th floor position A' as a destination position in the 'first floor position' (for example, The name of the company).

The first dashed box 210 represents a user interface through which the user can select one of the two suggested movement paths. The user interface on the left side of '1' in the first dotted line box 210 may be a user interface for selecting the first movement path presented by the service system 100. In addition, the right user interface in which '2' is written may be a user interface for selecting the second movement route presented by the service system 100. In the first screen 200, the first movement route is selected.

The second dashed line box 220 shows a user interface through which the user can select an interlayer moving means. From left to right can mean elevators, escalators and stairs, respectively. For example, if the user selects an elevator-shaped user interface of the second dashed box 220 (the user tabs the area of the corresponding icon), the service system 100 moves from the starting position to the destination position A moving route using an elevator can be provided to the user.

The third dashed line box 230 indicates the 'inside position' of the first floor, which is the starting position, and the 'location A' (the location identified by the specific facility name of the target building 120, for example) . When the user selects an area indicated by the third dotted line box 230, a screen (for example, the second screen 300 shown in FIG. 3) for resetting the starting position or the destination position is displayed on the user terminal 120 .

The &quot; Get directions &quot; user interface 240 may include a function for requesting to start the route guidance service from the start position to the destination position. When the user selects the route guidance start user interface 240, the route information on the route from the start position to the destination position is displayed on the basis of the position of the user terminal 120 (for example, Screen 400) may be provided to the user.

Also, the first screen 200 may display a map 250 related to the starting position or the destination position, and information 260 about the interlayer moving means existing on the moving route may be further displayed.

The second screen 300 of FIG. 3 shows an example of setting the start position. The fourth dotted line box 310 indicates that the user can directly input information for setting the start position. At this time, the input information may be used as a keyword to search for a facility or a point associated with the target building 120. For example, the input information is transmitted to the service system 100, and the service system 100 can search for facility information corresponding to the information input from the facility-specific information located inside the target building 120 . In this case, when there are a plurality of pieces of facility information corresponding to the input information, the service system 100 provides information on the plurality of facilities to the user, and determines the starting position using the information about the facility selected by the user . The destination position can also be set in the same way.

A fifth dotted line box 320 indicates a user interface for setting the current position of the user terminal 110 as a start position. The sixth dotted line box 330 shows a user interface for allowing a user to directly select a starting position on the map. If the user selects an area corresponding to the sixth dotted line box 330, the user may be provided with map information (e.g., map information associated with the location of the current user terminal 110 by default).

The seventh dotted line box 340 represents a user interface for setting a specific type of facility such as an entrance, a toilet, a smoking room, a breastfeeding room, etc. as a starting position or a destination position by a user. If the user selects the 'bathroom' icon shown in the seventh dotted line box 340, the user may be provided with a list of information about the closest toilets or toilets included in the target building 120.

The third screen 400 of FIG. 4 shows an example of a screen on which a route guidance service is provided. At this time, the route information may be displayed on the map, and the route guidance service may be provided based on the location 410 of the user terminal 110. For example, the third screen 400 indicates an instruction to turn right at position 420 of '3' according to location 410 of user terminal 110. The fourth screen 500 of FIG. 5 displays a list of guide information for each point included in the route information of FIG. At this time, the eighth dotted line box 510 shows an example in which the information about the interlayer moving means is included.

If the user moves to another layer through the interlayer movement means, the user terminal 110 may be provided with a card view for another layer. In other words, the service system 100 may provide each floor route information to the user terminal 110 in the form of a respective card view, and the user terminal 110 may be configured to provide, based on the location of the user terminal 110, The card view of the corresponding layer can be displayed on the screen. For example, in FIG. 5, when the user rides on the express elevator and moves to the sixth floor, the service system 100 may provide the card view configured for the sixth floor to the user terminal 110, ) May display a card view configured for the sixth floor. The service system 100 may provide a new card view to the user terminal 110 regardless of the request from the user terminal 110 as the layer in which the user terminal 110 is located is changed.

In addition, the service system 100 may provide information to the user terminal 110 about the identified interlayer moving means. At this time, the service system 100 can determine the movement path so that the selected inter-layer movement means included in the movement path information included in the user terminal 110 is included in the movement path information. For example, in the first screen 200 of FIG. 2, the user has selected the type of the interlayer moving means, but according to the embodiment, information about the interlayer moving means actually included in the target building 120 (for example, , Escalator, information on the position of each of the stairs, the time of movement from the current position, and the like), and generates the route information using the information selected by the user among the provided information.

In addition, the service system 100 can calculate the moving time for each moving route via the identified interlayer moving means, and determine the moving route based on the calculated moving time. For example, the service system 100 may provide the user terminal 110 with movement route information including the movement route having the shortest movement time.

For example, an elevator can distinguish an express elevator from a normal elevator, and calculate the time required for inter-story travel by applying a weight proportional to the number of moving floors. As another example, the escalator can calculate the time required for inter-layer movement by applying a weight according to the distance between the current layer and the node coordinates of the layer to be moved. More specifically, the time required for inter-layer movement can be calculated through a weight proportional to the two-dimensional coordinates on the escalator in the current layer and the two-dimensional coordinates on the escalator in the upper layer or the lower layer. In the case of the stairs, the time required for the inter-layer movement can be calculated by applying a weight proportional to the number of layers. The time required for the inter-layer movement is added to the time required for the movement in the layer, so that the movement time for each movement route can be calculated.

Hereinafter, a method for determining the indoor position of the user terminal 110 will be described.

The service system 100 may receive information about a wireless access point around the user terminal from a user terminal located within the target building. In addition, the service system 100 can determine the indoor location of the user terminal based on the similarity between the information about the surrounding wireless access points collected for each point of the target building and the information about the wireless access points around the user terminal.

FIG. 6 is a diagram illustrating a state in which a wireless access point is disposed in a target building according to an exemplary embodiment of the present invention. FIG. 7 is a diagram illustrating a wireless access point information collecting device, And the signal intensity according to the distance difference.

As shown in FIG. 6, a plurality of wireless access points AP1 to AP7 may be disposed inside the building. 2, the signal strength of each of the wireless access points AP1 to AP7 received by the user terminal is measured differently according to the location of the user.

For example, when the user moves from the A point 710 to the B point 720 as shown in FIG. 7, AP1 to AP3 are relatively closer to the user's terminal than the AP4 to AP7 at the A point 710 AP4 to AP7 are relatively closer to the user's terminal than AP1 to AP3 at the point B 720.

Signal strengths from the wireless APs at the A point 710 and the B point 720 are shown in Table 1 below.

Signal strength at point A Signal strength at point B AP 1 -40 -60 AP 2 -35 -40 AP 3 -45 -55 AP 4 -70 -55 AP 5 -75 -55 AP 6 -90 -60 AP 7 - -65

In this way, the service system 100 can determine the indoor position of the user by using the signal intensity from the neighbor AP depending on the location of the user.

FIG. 8 is a view for explaining a process of determining a user's indoor position in an embodiment of the present invention. FIG. 9 is a view for illustrating a weight applied according to a signal strength of a wireless access point Graph.

The service system 100 may perform fingerprinting at equal intervals as shown in FIG. For example, if we collect information about wireless access points from entrance 1 to entrance 2 inside the building, the collected locations are FP1, FP2, FP3, ... , And FP7.

Table 2 below shows the absolute coordinates of FP1 position, FP2 position and FP3 position in FIG. 8, and the signal strength from each wireless AP at each position.

FP 1 FP 2 FP 3 Latitude 37.385350 37.385337 37.385365 Hardness 127.121150 127.121378 127.121585 AP 1 -40 -50 -60 AP 2 -35 -37 -40 AP 3 -45 -50 -55 AP 4 -70 -63 -55 AP 5 -75 -65 -55 AP 6 -90 -75 -60

The location of the user can be accurately and quickly determined by using the actual location information (latitude / longitude) of the location to collect information on the wireless access points thus collected and the information about the wireless access point at each location.

Hereinafter, a process of determining the user location in the building as shown in FIG. 8 will be described with reference to the information in Table 2, for example.

The following Table 3 shows the signal strengths of the wireless access points that the user terminal located at a specific location in the environment shown in FIG. 8 moves from the specific time T to T + 2.

Time (T) Time (T + 1) Time (T + 2) AP 1 -45 -55 -50 AP 2 -40 -45 -50 AP 3 -50 -60 -55 AP 4 -60 -60 -45 AP 5 -65 -60 -65 AP 6 -80 -75 -70

If the signal strength of the wireless AP collected through fingerprinting is F.AP, and the signal strength of the wireless AP collected by the user terminal is C.AP, the similarity between the location of the user terminal and the location of FP1 at time T is Can be expressed as Equation (1).

Here, f (x) is a weight function and can have an exponential curve as shown in FIG.

Calculate the similarity between the signal strength of the wireless access point at each point as shown in Table 2 and the signal strength of the wireless access point at T, T + 1, T + 2 hours received from the user terminal as shown in Table 3 if,

When the degree of similarity between the user's terminal and the FP1 position is calculated at the position of time T,

Sim (FP1) = (100- (-40) - (-45) |) (11) + (100- | -35) -45) - (-50) | * (8) + (100- | -70 -60) | (5) + (100- | -75) - (-65) | * (100) | (-90) - (-80) |) (1)

= 3850

Sim (FP2) = (100- (-50) - (-45) |) (11) + (100- | -37) - -50) - (-50) | * (8) + (100- | -63) - (-60) | (5) + (100- | -65) - (-65) | * (100) | (-75) - (-80) |) (1)

= 3986

When the degree of similarity between the user's terminal and the FP3 position is calculated at the position of time T,

Sim (FP3) = (100- | -60- | -45) | (11) + (100- | -40- | -40) (-55) - (-50) | * (8) + (100- | -55) - (-60) | ) * (3) + (100- | -60) - (-80) | * (1)

= 3820

Can be obtained.

At this time, the position of the user terminal is determined as the position of the FP2 having the largest similarity value, and the position of FP2, the latitude of 37.385337 and the longitude of 127.121378, can be determined as the user position.

From Equation (1), it can be seen that the similarity between the position of the user terminal and the position of the FP can be calculated by the following equation (2).

B = | (F.APx - C.APx) |, Signal intensity difference: A value obtained by multiplying the collected signal by a constant value to obtain a larger value as the difference between the signal intensity (0 to -100) C = f (x), weighting by signal intensity: weight function by signal intensity obtained experimentally, respectively.

If we calculate the time as T → T + 1 → T + 2 as above,

The similarity between the user terminal and the FP position at time T is given by:

Sim (FP1) = (100- (-40) - (-45) |) (11) + (100- | -35) -45) - (-50) | * (8) + (100- | -70 -60) | (5) + (100- | -75) - (-65) | * (100) | (-90) - (-80) |) (1)

As a result of calculation as above, the user can obtain the result that the user moves from the FP2 position to the FP3 position in FIG. 8 and then moves back to the FP2 position.

In order to determine the indoor location of the user, the database may store information on surrounding wireless access points collected for each point within the target building. At this time, the information about the surrounding wireless access points collected for each point within the target building can be collected by the wireless access point information collecting device, the indoor map building device, and the like.

FIG. 10 is a block diagram illustrating an internal configuration of a service system according to an exemplary embodiment of the present invention, and FIG. 11 is a flowchart illustrating a service method according to an exemplary embodiment of the present invention.

The service system 1000 according to the present embodiment may correspond to the service system 100 described above and may include a processor 1010, a bus 1020, a network interface 1030, and a memory 1040 ). Memory 1040 may include an operating system 1041 and a service routine 1042. The processor 1010 may include a facility information holding unit 1011, a positioning unit 1012, and a route information generating unit 1013. At this time, the movement route information generation unit 1013 may include an interlayer movement unit confirmation unit 1240 and a movement route determination unit 1250 as described with reference to FIG. In other embodiments, the service system 1000 may include more components than the components of FIG. However, there is no need to clearly illustrate most prior art components. For example, the service system 1000 may further include other components such as a display or a transceiver.

The memory 1040 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. Also, the memory 1040 may store program codes for the operating system 1041 and the service routine 1042. [ These software components may be loaded from a computer readable recording medium separate from the memory 1040 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 1040 via the network interface 1030 rather than from a computer readable recording medium. For example, the service routine 1042 may be loaded into the memory 1040 based on the programs installed by the files that the developers provide over the network.

The bus 1020 may enable communication and data transfer between components of the service system 1000. The bus 1020 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or other suitable communication technology.

Network interface 1030 may be a computer hardware component for connecting service system 1000 to a computer network. The network interface 1030 may connect the service system 1000 to a computer network via a wireless or wired connection.

The processor 1010 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations of the service system 1000. The instructions may be provided by the memory 1040 or network interface 1030 and to the processor 1010 via the bus 1020. The processor 1010 may be configured to execute program codes for the facility information holding unit 1011, the positioning unit 1012, and the route information generating unit 1013. [ Such program code may be stored (e. G., In service routine 1042) in a recording device, such as memory 1040. [

At this time, the facility information holding unit 1011, the positioning unit 1012, and the movement route information generating unit 1013 may be configured to perform the steps 1110 to 1130 shown in FIG.

In step 1110, the facility information holding unit 1011 can maintain facility-specific information located inside the target building. As described above, the target building may mean any selected building among a plurality of buildings or a plurality of buildings connected to each other. Further, the facility-specific information may include information on a company located inside the target building (for example, a shop that has entered a department store or an outlet) and a convenience facility (toilet, elevator, escalator, stairs, etc.).

In step 1120, the positioning unit 1012 can determine the start position and the target position. For example, the starting position and the destination position can be selected through the user terminal. The positioning unit 1012 may transmit the map information in the target building to the user terminal and may determine the locations selected by the user terminal based on the map information as the start position and the target position. The starting position may optionally be determined to be the indoor position of the user terminal.

In step 1132, the movement path determination unit 1250 may determine a movement path to be included in the movement path information in consideration of the information on the identified interlayer movement means. In other words, the service system 1000 provides the route guidance service in the room through the route information, and when the inter-floor movement occurs, the route information used for the route guidance service is generated in consideration of the inter- .

At this time, the movement path determining unit 1250 can determine the movement path so that the inter-layer moving means selected by the user terminal among the identified inter-layer moving means is included in the moving path information. For example, when the user selects the escalator, the selected escalator is selected. When the elevator is selected, the movement route can be determined so as to pass through the selected elevator.

As another example, the movement path determination unit 1250 may calculate the movement time for each movement path via the identified interlayer movement means, and determine the movement path based on the calculated movement time. For example, a travel route with the shortest travel time can be recommended to the user. When a plurality of movement paths are recommended to the user, movement path information including a plurality of movement paths having the shortest movement time may be generated.

In this case, the not shown step may be performed by the route information providing unit 1210. At this time, the mobile route information providing unit 1210 may configure the card view including the route information according to each floor, and provide the card view of the floor where the user terminal is located based on the location of the user terminal have. At this time, when the layer in which the user terminal is located is changed, the service system 1000 can provide a new card view of the user terminal to the user terminal regardless of the request from the user terminal. The existing card view can be changed to a new card view and displayed on the screen in accordance with the change of the layer where the user terminal is located.

In addition, the service method according to the present embodiment may include a step (not shown) of receiving information on a wireless access point around the user terminal from a user terminal located inside the target building, (Not shown) of determining the indoor position of the user terminal based on the degree of similarity between the information on the wireless access point and the information on the wireless access point around the user terminal. These unpublished steps may be performed by the wireless access point information receiving unit 1220 and the indoor positioning unit 1230. For example, information about neighboring wireless access points collected for each point can be collected in an equal interval within the target building, and each of the wireless access points MAC (Media Access Control address and signal strength. At this time, the indoor positioning unit 1230 determines the indoor wireless positioning system based on the signal strengths of surrounding wireless access points collected at each point based on the MAC addresses of the surrounding wireless access points and the wireless access points around the user terminals, The degree of similarity between the signal strengths of the wireless access points around the user terminal can be calculated and the point of highest similarity can be determined as the indoor position of the user terminal.
