Description

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

Embodiments of the present invention relate to a technique for providing indoor location information, and more particularly, to a service system and method for providing information for inter-floor 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 includes information on 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.

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.

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. 2 is a block diagram for explaining an internal configuration of a service system in an embodiment of the present invention, and FIG. 3 is a flowchart illustrating a service method in an embodiment of the present invention.

The service system 200 according to the present embodiment may correspond to the service system 100 described above and may include a processor 210, a bus 220, a network interface 230, and a memory 240 ).

In other embodiments, the service system 200 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 200 may further include other components such as a display or a transceiver.

The memory 240 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 240 may store program codes for the operating system 241 and the service routine 242. [ These software components may be loaded from a computer readable recording medium separate from the memory 240 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 240 via the network interface 230 rather than from a computer readable recording medium. For example, the service routine 242 may be loaded into the memory 240 based on a program installed by the developers through files provided by the network.

The bus 220 may enable communication and data transfer between components of the service system 200. The bus 220 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 230 may be a computer hardware component for connecting service system 200 to a computer network. The network interface 230 may connect the service system 200 to the computer network via a wireless or wired connection.

The processor 210 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations of the service system 200. The instructions may be provided by the memory 240 or the network interface 230 and to the processor 210 via the bus 220. The processor 210 may be configured to execute program codes for the facility information holding unit 211, the positioning unit 212, and the route information generating unit 213. [ Such program code may be stored (e. G., In service routine 242) in a recording device, such as memory 240. [

At this time, the facility information holding unit 211, the positioning unit 212, and the movement route information generating unit 213 may be configured to perform the steps 310 to 330 shown in FIG.

In step 310, the facility information holding unit 211 may 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 320, the positioning unit 212 can determine a start position and a target position. For example, the starting position and the destination position can be selected through the user terminal. The positioning unit 212 may transmit the map information inside the target building to the user terminal and may determine the positions selected by the user terminal based on the map information as the start position and the destination position. The starting position may optionally be determined to be the indoor position of the user terminal.

In step 330, the movement path information generation unit 213 may generate the movement path information from the start position to the target position using the facility-specific information. Such movement route information may be utilized for a route guidance service or the like.

4 is a diagram showing another configuration of a processor included in a service system in an embodiment of the present invention. The moving route information generating unit 213 included in the processor 210 may include an interlayer moving means identifying unit 440 and a moving route determining unit 450. The interlayer moving means identifying unit 440 and the moving path determining unit 450 may be configured to perform the steps 331 and 332 of FIG.

In step 331, the interlayer moving means confirming unit 440 can confirm the information on the interlayer moving means included in the paths that can be moved from the starting position to the target position through facility information. Interlayer moving means may mean means used to move to another layer, such as, for example, an escalator, an elevator, a stair,

In step 332, the movement path determination unit 450 may determine a movement path to be included in the movement path information in consideration of information on the identified interlayer movement means. In other words, the service system 200 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 450 can determine the movement path so that the selected inter-layer moving means, selected in the user terminal, 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 450 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 another embodiment, the movement route information generating unit 213 may further include the interlayer moving information providing unit 460 as needed. For example, in the service method according to the present embodiment, step 330 may further include providing information (not shown) to the user terminal about the identified interlayer moving means. In this case, the unillustrated step may be performed by the interlayer moving means information providing unit 460.

The processor 210 may further include at least one of a mobile route information providing unit 410, a wireless access point information receiving unit 420, and an indoor positioning unit 430.

For example, the service method according to the present embodiment may further include a step (not shown) of providing the route information to the user terminal after the step 330. In this case, the unrepresentation step may be performed by the route information providing unit 410.

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 non-illustrated steps may be performed by the wireless access point information receiving unit 420 and the indoor positioning unit 430. 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 430 determines the signal strengths of neighboring 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.
