Hereinafter, the main configuration and operation method of the terminal 100 according to an embodiment of the present invention will be described.

FIG. 2 is a block diagram illustrating a main configuration of a terminal according to an embodiment of the present invention shown in FIG. 1 .

1 and 2, the terminal 100 according to an embodiment of the present invention includes a sensor information collection module 110, a reference point setting module 120, an inter-floor information setting module 130, and a user location floor calculation module ( 140) may be included.

Here, a 'module' is a component that each performs a predetermined function, and may be implemented as hardware, software, or a combination of hardware and software. For example, the 'module' may mean a program module, which is executed by a processor to perform a predetermined function, including software components, object-oriented software components, class components, and Components such as task components, processes, functions, properties, procedures, subroutines, segments of program code, drivers, data, databases, data structures, tables, arrays , and variables. In addition, components and functions provided in '~modules' may be combined into a smaller number of components and '~modules' or may be further separated into additional components and '~modules'.

In more detail with respect to each module constituting the terminal 100 of the present invention, the sensor information collection module 110 collects necessary information by using various hardware sensor resources. For example, the sensor information collection module 110 may include an illuminance sensor, and may collect information on changes in brightness and darkness around the user through the illuminance sensor. In addition, the sensor information collection module 110 includes a microphone and may collect information about surrounding noise.

In addition, the sensor information collection module 110 may collect information on the beacon signal using a wireless communication device, and may include a temperature sensor and collect sensing information such as temperature change using the temperature sensor. In addition, the sensor information collection module 110 of the present invention includes an altitude sensor, and may collect an altitude value for the current height by using the altitude sensor.

The sensor information that can be collected by the sensor information collection module 110 is not limited to the above example, and various types of necessary information may be sensed and collected according to an embodiment of the present invention.

The reference point setting module 120 serves to set a reference point for position estimation according to the present invention. The reference point setting module 120 may first determine that the user enters the building from the outside by using the information collected through the sensor information collection module 110 .

For example, when the current date and time information is collected through the sensor information collection module 110 and it is a summer day, the temperature is generally higher outdoors, so the temperature information collected through the sensor information collection module 110 is When the temperature is changed from the high temperature to the low temperature, the reference point setting module 120 may determine that the user has moved from the outdoor to the indoor. In addition, when the current time collected through the sensor information collection module 110 is noon, and the illuminance value measured through the illuminance sensor changes from light to dark, the reference point setting module 120 determines that the user moves from outdoors to indoors. can be judged as In addition, when the terminal 100 of the present invention uses a beacon signal, it transmits a sensed beacon signal to the service device 200, checks the location information corresponding to the beacon signal, and the corresponding beacon signal is transmitted to the sensor information collection module 110 ), the reference point setting module 120 may determine that the user has moved from the outdoor to the indoor. In this case, the reference point setting module 120 sets various criteria for determining whether the user has moved from the outdoors to the indoor, and the conditions may be flexibly changed according to the hardware resources provided in the terminal 100 .

In addition, the information required in the process of collecting sensor information of the present invention and determining whether it has moved from outdoors to indoors may use at least one or more sensor information, and may be determined by considering two or more sensor information in combination. .

If it is determined that the user enters the building from the outdoors, that is, enters the building through this process, the reference point setting module 120 requests the sensor information collection module 110 to measure the altitude value, and the sensor information collection module 110 . The measured altitude value is set as the reference point. Here, the reference point means the first floor of the building.

The inter-floor information setting module 130 serves to set inter-floor information on the height between the floors. Here, the inter-floor information may mean inter-floor average height information or may be height distribution information for each floor. In addition, the inter-floor information of the present invention may be set using a statistically calculated average height between floors of a building. For example, if the average inter-floor height of a building built within the last 5 years is 2.7m, the inter-floor information setting module 130 of the present invention confirms the building built within 5 years by checking attribute information (eg, year of establishment, etc.) about the building Then, the inter-floor information can be set to the average inter-floor height of 2.7 m. In addition, the inter-floor information setting module 130 of the present invention may periodically request the sensor information collection module 110 to measure the altitude value, and correct or set the inter-floor information in consideration of the periodically measured altitude value and the average inter-floor height. have.

In addition, the sensor information collection module 110 may check information on past elevation values for each floor and generate inter-floor information using the generated elevation distribution information for each floor. For example, if the elevation value at the location estimated as the 3rd floor in the same building in the past is 5.4m and the elevation value at the location estimated as the 4th floor is 8.1m, the interfloor information setting module 130 uses this to You can also set inter-layer information. In this case, the inter-floor information setting module 130 may set inter-floor information by interworking with the service device 200 using information measured by other terminals in the corresponding building.

The user location floor calculation module 140 uses the reference point set through the reference point setting module 120 and the current altitude value collected through the inter-floor information and the sensor information collection module 110 set through the inter-floor information setting module 130 . It plays a role of calculating the number of floors where the user is currently located.

More specifically, the user location floor calculation module 140 of the present invention requests the sensor information collection module 110 to measure the current altitude value. Here, the user location floor calculation module 140 may be measured after a predetermined time elapses after the user enters the building, or may be measured when a specific event occurs. For example, when a specified event occurs, such as when a specific application is driven after the user enters the building, the user location floor calculation module 140 measures the current altitude value with the sensor information collection module 110 to estimate the current user location. can request

And when the current altitude value is transmitted from the sensor information collection module 110, the user location floor calculation module 140 of the present invention calculates the altitude value set as a reference, that is, the first floor by the reference point setting module 120 from the current altitude value. Calculate the subtracted height.

In addition, the user location floor calculation module 140 may calculate the floor in which the current user is located by dividing the height obtained by subtracting the elevation value set as a reference from the current elevation value by the average height between floors. For example, if the current altitude value is 50m, the standard altitude value is 5m, and the average height between floors is 5m, the height of 45m minus the current altitude value minus the standard altitude value is divided by 5m, the average height between floors. The user location floor calculation module 140 may confirm that the user of the terminal 100 is currently located on the ninth floor.

In addition, the user location floor calculation module 140 of the present invention may extract the corresponding floor information by comparing it with the altitude distribution information for each floor. In other words, the number of user location floors can be checked using past data, and the user location floor calculation module 140 checks whether user location floor calculation information stored in correspondence with the building in the past exists. In this case, the user location floor calculation module 140 of the present invention may use information stored therein, and may use past data in conjunction with the service device 200 .

And the user location floor calculation module 140 extracts the corresponding floor information by using the past altitude value information for each floor. For example, if the current altitude value is 50 m and there is floor information corresponding to 50 m in the past, corresponding The floor information to be used can be calculated as the user location floor. In this case, the user location floor calculation module 140 may set a range value in consideration of the sensor sensitivity collected by the sensor information collection module 110, for example, the user location floor calculation module 140 has a current altitude value of 50 m and a past Even if there is no floor information matching 50m in the , if there is information corresponding to a certain range such as 48m within a certain range, the floor information corresponding to the corresponding height may be used as the floor information corresponding to the current elevation value of 50m.

If the user's current location floor is confirmed through this process, the user location floor calculation module 140 can store it and use it for future location estimation.

As described above, the main configuration and operation of the terminal 100 according to an embodiment of the present invention has been described.

Prior to being described with reference to FIG. 3 , as described above, the method for estimating a location in a building according to an embodiment of the present invention may be performed by the terminal 100 or by the service device 200 . In addition, it may be achieved through interworking between the terminal 100 and the service device 200 .

A method for estimating a location in a building according to an embodiment of the present invention will be described in more detail with reference to FIGS. 4 to 9 .

First, FIG. 4 is a flowchart illustrating a reference point setting step in a method for estimating a location in a building according to an embodiment of the present invention.

1 and 4 , an apparatus for executing the method for estimating a location in a building of the present invention, for example, the terminal 100 collects various hardware sensor resources provided in a predetermined period unit through the sensor information collection module 110 . sensor information is collected by using (S101).

Here, the sensor information collected in units of a certain period is for determining whether the user has entered the building from the outside, that is, inside the building. You can collect information about temperature changes or collect information about temperature changes.

And the reference point setting module 120 of the terminal 100 determines whether the user has moved from the outdoor to the indoor based on this (S103).

In this case, the reference point setting module 120 of the terminal 100 may request and collect various kinds of sensor information necessary for determining whether the user has moved from the outdoor to the indoor to the sensor information collection module 110, for example, the current date. and time information is collected to determine that the outdoor temperature is generally higher on a summer day, and thus, when the temperature changes from a high temperature to a low temperature, it may be determined that the outdoor area has moved to the indoor area. Also, when the current time is noon and the illuminance value measured through the illuminance sensor changes from bright to dark, the reference point setting module 120 of the terminal 100 may determine that the user has moved from the outdoor to the indoor.

In addition, when the terminal 100 of the present invention can receive the beacon signal, the reference point setting module 120 transmits the beacon signal sensed through the sensor information collection module 110 to the service device 200, and When the location information corresponding to the signal is received from the service device 200, it is checked and when the corresponding beacon signal is sensed, it can be determined that the user has moved from the outdoor to the indoor.

In addition, the reference point setting module 120 may set various criteria for determining whether the user of the terminal 100 has moved from the outdoor to the indoor. Here, the criterion may be set by the user or may be set by the service device 200 . In addition, the conditions may be flexibly changed according to hardware resources provided in the terminal 100 . In addition, the information required in the process of collecting sensor information of the present invention and determining whether it has moved from outdoors to indoors may use at least one or more sensor information, and may be determined by considering two or more sensor information in combination. .

If it is determined that the user enters the building from the outdoors, that is, enters the building through this process, the reference point setting module 120 of the terminal 100 requests the sensor information collection module 110 to measure the altitude value, and collects the sensor information. The module 110 measures the altitude value for the current height using the altitude sensor (S105).

In addition, when the altitude value measured through the sensor information collection module 110 is transmitted, the reference point setting module 120 of the terminal 100 sets the measured altitude value as the reference point (S107). Here, the reference point means the first floor of the building.

The subsequent process will be described with reference to FIGS. 5 to 7 .

5 is a flowchart illustrating an inter-floor information setting step in a method for estimating a location in a building according to an embodiment of the present invention, and FIG. It is a flowchart for explaining the information setting step, and FIG. 7 is a flowchart for explaining the inter-floor information setting step in a method for estimating a location in a building according to another embodiment of the present invention.

First, referring to FIGS. 1 and 5 , the interlayer information setting module 130 of the terminal 100 of the present invention sets the interlayer information after the reference point is set through the reference point setting module 120 . In this case, the inter-floor information setting module 130 of the terminal 100 may request and receive inter-floor average height information from the service device 200 ( S201 ).

In addition, when the inter-floor average height information is received from the service device 200 , the inter-floor information setting module 130 of the terminal 100 may set the received inter-floor average height information as inter-floor information.

More specifically, in general, buildings are calculated as one floor every 4 meters according to the building law, but in actual construction, the average height between floors may vary depending on the current trend or other reasons, so the terminal ( The inter-floor information setting module 130 of 100) does not simply set the legally determined height as the average inter-floor height, but requests the inter-floor average height information from the service device 200 and receives the information to set the inter-floor information. This makes it possible to check the average height between floors more accurately.

In addition, the inter-floor information setting module 130 of the terminal 100 of the present invention checks through the sensor information collection module 110 whether a beacon signal received when entering the building is present, and then, if there is a beacon signal, the beacon signal beacon identification information may be extracted from and transmitted to the service device 200 . In addition, the service device 200 may check building information and attribute information corresponding to the beacon signal, and may provide it to the terminal 100 after confirming more accurate inter-floor average height information accordingly.

On the other hand, the terminal 100 of the present invention may measure the altitude value in units of a certain period and set the inter-floor information based on this.

Referring to FIG. 6 , after the reference point is set through the reference point setting module 120 , that is, after the initial altitude value is measured, the terminal 100 responds to the request of the inter-floor information setting module 130 . The information collection module 110 measures the current altitude value after a predetermined time (S211).

Then, the inter-floor information setting module 130 of the terminal 100 checks the difference between the previous altitude value and the current altitude value measured through the sensor information collection module 110 (S213). This may be set as inter-layer information (S215). For example, when the user walks up from the first floor to the second floor, the terminal 100 measures the altitude value after a predetermined time set in consideration of the average walking time after measuring the first floor, that is, the first altitude value, and The difference between the altitude value and the previous altitude value can be set as inter-floor information.

In addition, the inter-floor information setting module 130 of the terminal 100 of the present invention calculates the current altitude value after setting the reference point, and divides the height obtained by subtracting the previous altitude value from the current altitude value by the inter-floor average height information as inter-floor information. You can also set Since this process is performed in a predetermined period unit, it is possible to more accurately calculate the average height between floors.

Also, the inter-layer information setting module 130 of the terminal 100 of the present invention may set inter-layer information using past information.

Referring to FIG. 7 , as shown in FIG. 7 , the inter-floor information setting module 130 of the terminal 100 of the present invention checks whether the past user location floor calculation information exists ( S221 ). At this time, the inter-floor information setting module 130 of the terminal 100 of the present invention identifies the building information that can recognize the building, for example, the building information corresponding to the beacon identification information of the beacon signal collected in the building, and responds accordingly. It can be checked whether pre-stored past measurement information or inter-layer information exists.

At this time, the information for confirming the building information may include not only the beacon signal but also various information that may be generated in the building, for example, building access authentication information generated when entering the building, in the store located in the building. You can check information to identify a building in various ways, such as payment information, and check past data based on this.

In addition, the inter-floor information setting module 130 of the terminal 100 of the present invention can transmit information for recognizing a building to the service device 200 and receive and check past data from the service device 200, at this time , it is also possible to use information measured by other users in the building.

That is, the inter-floor information setting module 130 of the terminal 100 of the present invention transmits information for identifying a building to the service device 200, and the service device 200 that receives the information is measured by another user in the corresponding building. Check that the information is present. For example, if the information measured by user A is '8th floor, 21.6m', the average height between floors can be checked by comparing the height value with respect to the reference point measured by the terminal 100, and the service device 200 provides such information to the terminal 100, and the interlayer information setting module 130 of the terminal 100 may set the interlayer information based on this (S223).

The subsequent process will be described with reference to FIGS. 8 and 9 .

8 is a flowchart illustrating a user location floor calculation step in a method for estimating a location in a building according to an embodiment of the present invention, and FIG. 9 is a method for estimating a location in a building according to another embodiment of the present invention. It is a flowchart for explaining the user location floor calculation step.

First, referring to FIG. 8 , the user location floor calculation module 140 of the terminal 100 of the present invention requests the sensor information collection module 110 to measure the altitude value, and the sensor information collection module 110 provides the current altitude value. is measured (S301). Here, the step of measuring the current altitude value may be measured after a predetermined time elapses after the user of the terminal 100 enters the building.

And when the current altitude value is transmitted from the sensor information collection module 110 to the user location floor calculation module 140 of the terminal 100 of the present invention, the altitude of the reference point measured in step S105 of FIG. 4 from the measured current altitude value Check the height minus the value (S303).

In addition, the user location floor calculation module 140 of the terminal 100 may calculate the floor on which the current user is located by dividing the height obtained by subtracting the altitude value set as a reference from the current altitude value by the average height between floors (S305). For example, if it is assumed that the current elevation value is 50 m, the standard elevation value is 5 m, and the average height between floors is 5 m, the user location floor calculation module 140 subtracts the elevation value set as a reference from the current elevation value is 45 m By dividing by 5 m, which is the average height between floors, it can be confirmed that the user of the terminal 100 is currently located on the ninth floor.

In addition, the user location floor calculation module 140 of the terminal 100 of the present invention may determine the number of user location floors using past data.

Referring to FIG. 9 , the user location floor calculation module 140 of the terminal 100 of the present invention checks whether user location floor calculation information stored in correspondence with the building in the past exists ( S311 ). In this case, the user location floor calculation module 140 of the terminal 100 of the present invention may use information stored therein, and may use past data in conjunction with the service device 200 .

In addition, the user location floor calculation module 140 of the terminal 100 may extract the corresponding floor information by using the past altitude value information for each floor (S313). For example, when the current elevation value is 50 m and floor information corresponding to 50 m exists in the past, the user location floor calculation module 140 may calculate the corresponding floor information as the user location floor ( S315 ).

At this time, the user location floor calculation module 140 may set the range value in consideration of the sensor sensitivity of the terminal 100 . For example, the user location floor calculation module 140 of the terminal 100 has a current altitude value of 50 m and a past Even if there is no floor information matching 50m in the , if there is information corresponding to a certain range such as 48m within a certain range, the floor information corresponding to the corresponding height may be used as the floor information corresponding to the current elevation value of 50m.

When the user's current location floor is confirmed through this process, the user location floor calculation module 140 of the terminal 100 stores it and can be used for future location estimation.

As described above, according to the method for estimating a location in a building according to an embodiment of the present invention, when estimating the location using the altitude information measured through the altitude sensor, the user's location is estimated in consideration of the reference point and the inter-floor information, so that only the altitude information is used. It is possible to increase the accuracy of the position estimation compared to the case of the present invention.

In addition, according to the present invention, by estimating the location of the user in the building in consideration of the altitude information, the reference point, and the inter-floor information, it is possible to estimate the location even when the information about the building is not known.

In addition, it is possible to more quickly and more accurately estimate the user's location in the building by setting the inter-floor information or checking the information about the building when estimating the user's location according to the implementation method.
