For example, when receiving the wireless access point information of the APs 13 and 14 in the integrated positioning providing system 200, the position determining unit 222 may determine that the reception of the AP identification information included in the AP list 510 related to the C- The layers coinciding with the identification information of the APs 13 to 14 can be determined as the layer information of the integrated positioning providing system 200. [ That is, the positioning unit 222 can determine the outdoor area 1F of the complex building corresponding to the C area as the floor information in which the integrated positioning providing system 200 is located. Then, in step 820, the display control unit 223 can display a map corresponding to the determined layer. For example, the display control section 223 can display an outdoor map around the complex building corresponding to the outdoor area 1F on the display of the integrated positioning providing system 200. [ At this time, the display control unit 223 can display the point corresponding to the GPS coordinate information of the integrated positioning providing system on the 1F outdoor map by using the display information indicating the current position of the integrated positioning providing system (for example, Location indication).

As another example, when it is determined that the integrated positioning providing system is located in area A and the wireless access point information of AP 13 and AP 14 is received in integrated positioning providing system 200, It can be confirmed that the AP 13 and the AP 14 do not exist in the associated AP list 520 and the positioning unit 222 can determine that the AP 13 and the AP 14 exist based on the previous position information and altitude information of the previously- The layer information of the integrated positioning providing system 200 can be determined. For example, the area A may be a roof parking space formed in the building A 5F, and may be an outdoor area within the building A. Then, if there are no APs installed in the rooftop parking lot, the AP list 520 associated with the A area does not include the AP and may include a value of "none" or "null ". Here, a specific operation for determining the layer information based on the AP list will be described later with reference to FIG.

FIG. 9 is a diagram provided for explaining an operation of determining layer information based on previous position information and altitude information, in an embodiment of the present invention. FIG.

According to FIG. 9, the complex building may be composed of an A building of 3F, a B building of 6F, and an outdoor square of a first floor, and the integrated positioning information of the complex building includes A area 901, A 3F floor parking lot of building A), B area 902 corresponding to the first outdoor area in building B, representing the 5F sky park of building B, representing the 6F roof of building B, and the second outdoor area of building B A C area 903, and a D area 904 corresponding to the outdoor outdoor area of the complex building.

At this time, if it is determined that the integrated positioning providing system 200 is located in the 5F sky park of building B and the integrated positioning providing system 200 is located in the B area 902, the AP is not installed in the 5F sky park , It can be confirmed that APs corresponding to the wireless access point information received in the integrated positioning providing system 200 do not exist in the AP list related to the B region. Then, the positioning unit 222 can determine the layer information of the integrated positioning providing system 200 based on the previous position information and the altitude information of the previously-positioned integrated positioning providing system 200. [ Here, the altitude information may be sensed by an atmospheric pressure sensor mounted on the integrated positioning providing system 200. For example, the atmospheric pressure sensor may transmit the generated altitude information to the processor 220 by sensing an altitude change due to the movement of the integrated positioning system 200 based on the sea level. Then, the processor 220 can use the altitude information to determine the layer information of the integrated positioning providing system 200.

For example, if the position of the previously-positioned integrated positioning system is 6F of the B building, the altitude information at the previously located position is 62, and the altitude information at the currently located position is 50, Can determine that the integrated positioning providing system 200 has moved between layers when the altitude variation value 12, which is the difference between the altitude information at the previous position and the altitude information at the current position, is equal to or greater than the predetermined reference altitude value 10. Here, the reference altitude value may be set based on the inter-layer height of each area. At this time, if the altitude value included in the altitude information of the current position is larger than the altitude value included in the altitude information of the previous position, the positioning unit 222 determines that the altitude information has moved to the upper layer, You can decide. For example, the positioning unit 222 may determine that the integrated positioning providing system 200 has moved from 6F to 5F sky park of the B building, and may determine the floor information of the integrated positioning providing system 200 as 5F. Then, the display control unit 223 can display the map corresponding to the 5F sky park on the display of the integrated positioning providing system 200, and display information on the map corresponding to the GPS coordinate information of the integrated positioning providing system The present position of the integrated positioning providing system 200 can be displayed. The display control unit 223 displays on the map the GPS coordinate information (latitude and longitude) indicating the current location, the complex building name to which the B building name or the B area belongs, the layer string information (for example, 5F) Information and the like can be further displayed.

As another example, if the position of the previously-located integrated positioning providing system is 5F of the B region, the altitude information at the previously located position is 50, the altitude information at the currently located position is 45 and the altitude change value 5 is the reference altitude When the value is 10 or less, the positioning section 222 can determine that the integrated positioning providing system 200 has not performed the interlayer movement. Then, the positioning unit 222 can determine the current layer information of the integrated positioning providing system as 5F, which is the layer information corresponding to the previously positioned position.

As described above, the integrated positioning providing system 200 can utilize the previous position information and the altitude information in addition to the GPS coordinate information so that the integrated positioning providing system 200 is located in the outdoor area of the building or the outdoor area 1F The floor information of the integrated positioning providing system 200 can be determined even when it is located in a plurality of outdoor areas in the building or in a plurality of outdoor areas in the building. The integrated positioning providing system 200 may be configured such that the integrated positioning providing system 200 is located at a position where a georeferencing issue or a GPS error is likely to occur, such as an edge between an outdoor area in a building and an outdoor area around a building , The layer information may be corrected using the previous position information and the altitude information.

10 is a view for explaining an operation of correcting the position of an integrated positioning system using previous position information and altitude information in an embodiment of the present invention.

Referring to FIG. 10, the GPS positioning system and the georeferencing issue cause the integrated positioning system 200 to provide an actual location in an outdoor area of a building such as a 3F rooftop parking lot of building A, a 5F sky park of building B, It is often the case that the position of the integrated positioning system 200 is determined as the 1F outdoor area around the A building and the 1F outdoor area around the B building.

For example, when the integrated positioning providing system 200 is located at the edge of the 3F roof parking lot corresponding to the area boundary between the building A and the 1F square, the GPS coordinates of the integrated positioning providing system 200 The area corresponding to the information can be determined as the D area corresponding to the 1F square of the complex building (i.e., the outdoor area around the building). Since the ceiling of the 3F roof is opened, the integrated positioning system 200 located at the 3F can receive the wireless access point information from the APs installed in the convenience store, the cafe booth, and the like located on the 1st floor. Then, APs received from the integrated positioning providing system 200 exist in the AP list related to the D region, and the floor information of the integrated positioning providing system 200 may be determined to be 1F instead of 3F which is the actual position 1002 have. That is, a point 1001 corresponding to the GPS coordinate information in the outdoor area corresponding to the 1F square can be determined as the current position of the integrated positioning providing system 200. In order to solve the positioning error due to the GPS error, the positioning unit 222 can correct the floor information, that is, the current position of the integrated positioning providing system 200, using the previous position information and the altitude information.

For example, if the building and floor information corresponding to the previously located previous position information is 2F of the building A, the previous altitude information is 20, and the current altitude information is 30, the altitude change value 10 is greater than or equal to the reference altitude value 10, Since the altitude information is higher than the previous altitude information, the location determining unit 222 determines the floor information of the integrated positioning providing system 200 as the 3F of the A building, and provides the combined positioning information to the map information corresponding to the 3F of the A building The map corresponding to the GPS coordinate information of the system 200 can be map-matched. That is, the current position of the integrated positioning providing system 200 can be corrected from the point 1001 of 1F to the point 1002 of 3F.

As another example, the present integrated positioning system 200 is located at 1F, but may be located at 3F. In this case, since the area corresponding to the previously located position information is 1F and the altitude change value (for example, when the altitude change value is 2) is less than the reference altitude value 10, 200) does not migrate to the layer. Then, the positioning unit 222 can correct the current position from the point 1002 of 3F to the point 1001 of 1F.

As another example, there exist two outdoor areas (for example, 5F sky park and 6F roof) in the building B, and the integrated positioning providing system 200 is moved from the 5F sky park to the 6F roof or 6F roof To the 5F sky park. As described above, in the case of moving in the outdoor area, the georeferencing issue may cause the current position of the integrated positioning system to be determined as the 1F point (1003) around the B building area. Then, the positioning unit 222 can correct the current position based on the previous position information and the altitude information (previous altitude information and current altitude information). For example, if the integrated positioning system 200 is located at 5F, the map is matched to the 5F point 1004, and if the integrated positioning system 200 is located at 6F, the map is matched to the 6F point 1005. [ Then, the display control section 223 can display on the map display information indicating the current position corrected from the 1F point 1003 to the 5F point 1004 through map matching to the 5F point 1004.

The outdoor area 1120 in the building may be formed of a plurality of layers , And the outdoor area around the building may also be formed of a plurality of layers.

In FIG. 11, indoor positioning within a building may be located using fingerprint-based positioning. For example, the signal strength of each wireless access point measured at a fingerprint point (FP), which is a virtual point designated inside the building, and the signal strength of wireless access points received at the integrated positioning providing system 200, Can be performed.

11, when the integrated positioning system 200 moves to the 2F square through the inclined guide for the steps or the bicycle, the baby carriage, and the wheelchair in the 1F square, the positioning unit 222 determines It can be determined that the integrated positioning providing system 200 is located in the outdoor area 1120 in the building and it can be confirmed whether or not the determined outdoor area is the positionable area. For example, in the case of a positionable area, the positioning unit 222 may transmit the floor information mapped to the outdoor area 1120 corresponding to the GPS coordinate information of the integrated positioning providing system 200 to the integrated positioning providing system 200, (For example, 2F). In addition, the location determination unit 222 may determine the location of the integrated location providing system 200 based on the wireless access point information of each of the APs received in the integrated positioning providing system 200 and the AP list corresponding to the determined outdoor area 1120, (For example, 2F) corresponding to the current position of the layer. Conversely, even when moving from 2F to 1F, the positioning unit 222 may determine whether the layer is changed based on the altitude information, and determine the layer information corresponding to the current position. As such, the outdoor area 1120 in the building and the outdoor area 1130 in the vicinity of the building are divided into a plurality of layers and connected through a moving means, such as 1F square and 2F square, or the outdoor area 1120 Even if the outdoor area 1130 around the building is divided into a plurality of layers, the integrated positioning providing system 200 may divide the floor in the outdoor area so that the current location of the integrated positioning providing system 200 .

At this time, when the integrated positioning providing system 200 moves from the 2F square to the indoor area in the building connected to the 2F square, the display control unit 223 displays a map corresponding to the 2F indoor area of the building in the integrated positioning providing system 200 On the display of FIG.

For example, the point 1140 corresponding to the GPS coordinate information of the integrated positioning system 200 is included in the area around the entrance to and departing from the 2F building indoor area, or the previously located position corresponds to the 2F square If the currently positioned position is the outdoor area, the display control unit 223 can display the 2F indoor map on the display. The display control unit 223 displays a part of the outdoor area around the doorway connected to the 2F square on the indoor map and displays display information indicating the current position of the integrated positioning providing system 200 in the outdoor area .

As another example, when the integrated positioning system 200 is located in the 1F indoor area and moves to a square corresponding to the 1F outdoor area connected to the 1F indoor area, the display control unit 223 can display a map related to the 1F square have. For example, a point 1150 corresponding to the GPS coordinate information of the integrated positioning providing system 200 is included in the area around the entrance in the 1F building connected to the 1F square in the 1F building indoor area, The display control unit 223 can display a map related to the 1F square on the display when the currently positioned position is the outdoor area 1130 corresponding to the 1F square.

As another example, when the integrated positioning system 200 located in the 2F square moves to the 1F square using a moving means such as an escalator or a stair, the display control unit 223 can display a map related to the moving floor . For example, when the point 1160 corresponding to the GPS coordinate information of the integrated positioning providing system 200 is included in the area around the escalator of the predetermined 2F square, the positioning unit 222 determines that the integrated positioning providing system 200 is located at 2F Lt; RTI ID = 0.0 > 1F. ≪ / RTI > Then, the display control section 223 can display a map corresponding to the 1F square on the display of the integrated positioning providing system 200. [ On the other hand, when the point 1170 corresponding to the GPS coordinate information of the integrated positioning providing system 200 is included in the area around the escalator of the predetermined 1F square, the display control unit 223 provides the map corresponding to the 2F square to the integrated positioning Can be displayed on the display of the system 200.
