In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.
In this specification, the reference beacon signal information means beacon signal information obtained from a plurality of beacons at a reference position (specific point).
Hereinafter, a position information providing system according to the present invention will be described with reference to FIGS. 1 to 4. FIG.
1 is a diagram illustrating an example of a location measurement environment according to the present invention. Referring to FIG. 1, a plurality of beacons 10 (A, B, C, D, E, and F) emit a wireless beacon signal to identify a specific object or a user. In this case, the beacon 10 may be a base station, a wireless AP, a Bluetooth beacon, a ZigBee module, or other wireless transmitting / receiving device, and the wireless beacon signal information (hereinafter, And the received signal strength.
The beacon signal information is collected from the plurality of beacons 10 at the reference positions 20 (1, 2, 3, 4, 5, 6, 7, 8) . The beacon signal information collected at the reference position 20 may be stored in the beacon information-based beacon information database 100 shown in FIG. 3 in the form of a table as shown in FIG.
When a specific object and / or user requests a location confirmation from the location information system at a specific point, the terminal can receive the beacon signal information Tr at the location request point 30 and transmit it to the location information system. At this time, the beacon signal information Tr is received from the plurality of beacons 10 at a specific time interval from the plurality of beacons 10 at a specific time interval, and may include beacon information and signal strength of each beacon.
3, the position information system includes a database 100 for storing reference beacon signal information collected from one or more beacons at a reference position, a communication unit 400 for receiving a position confirmation request from a terminal located at an arbitrary point, An error correction preprocessing unit 300 for preprocessing the beacon signal information included in the position confirmation request using the beacon signal information at the reference position, And a controller 200 for calculating the position of the terminal.
When the location information system receives the location confirmation request from the terminal 30 located at an arbitrary point, that is, the terminal 30 receives the beacon signal information received from the plurality of beacons 10 (400) And transmits the beacon signal information included in the beacon signal information to the error complement preprocessing unit 300.
The error correction preprocessing unit 300 preprocesses the beacon signal information included in the position confirmation request using the reference beacon signal information stored in the database 100, and can use arithmetic calculation in the preprocessing process. For example, the error correction preprocessing unit 300 may supplement the beacon signal information missing in the position check request using the reference beacon signal information stored in the database 100. In another embodiment, if the beacon signal information stored in the location confirmation request differs from the reference beacon signal information stored in the database 100, the error supplementing preprocessing unit 300 may include in the location confirmation request based on the reference beacon signal information By correcting the beacon signal information, the difference can be compensated. In another embodiment, if the beacon signal information stored in the location confirmation request differs from the reference beacon signal information stored in the database 100, the error supplementing preprocessing unit 300 may determine that the beacon signal information is different from the reference beacon signal information stored in the database 100, The beacon signal information included in the position confirmation request can be corrected using the beacon signal information received from the plurality of beacons. The corrected beacon signal information is stored in the database 100 as reference beacon signal information corresponding to an arbitrary position and can be utilized for measuring the position of a terminal located at another point.
The database 100 stores reference beacon signal information collected from a plurality of beacons at a reference location 20. [ 2, the database 100 includes reference beacon signal information collected from a plurality of beacons at each reference position 20. The beacon signal information Tr included in the position confirmation request of the terminal 30 includes, (600) is as follows. Tr = A: x, B: -90 dBm, C: x, D: -60 dBm, E: x, F: x. This is an embodiment in which beacon signal information of beacons A, C, E, and F is missing in the position confirmation request (Tr)
In this case, the error correction preprocessing unit 300 may supplement the missing beacon signal information using the reference beacon signal information stored in the database 100. [ The error compensation preprocessing unit 300 can search the database 100 for reference reference positions having beacon signal information included in the position check request, that is, reference beacon signal information corresponding to B: -90 dBm and D: -60 dBm .
In the table of FIG. 2, since the reference beacon signal information of the reference position 4 610 and the reference position 7 620 are B: -90 dBm and D: -60 dBm, they have the same value as the beacon signal information included in the position confirmation request, Therefore, the reference position 4 610 and the reference position 7 620 become reference reference positions.
Next, the error correction preprocessing unit 300 multiplies the received signal strength of the missing first beacon (beacon A, C, E, F) by the first beacon (beacon A, A, C, E, and F), the missing beacon signal information can be supplemented. As a result, the complementary beacon signal information Tr '630 includes Tr' = A: -90 dBm, B: -90 dBm, C: -90 dBm, D: -60 dBm, E: -90 dBm, and F: -90 dBm.
If the position information system does not undergo a preprocessing process in the error correction pre-processing unit 300, since the position information system refers to only the beacon signal information about the beacons B and D as in the beacon received signal intensity table of FIG. 2, An error will occur in the positional information by determining the reference position 4 or the reference position 7 having the characteristics most similar to the received signal strengths of B, D as the position of the terminal 30. However, the position information system can obtain accurate position information through the preprocessing and the preprocessing process described below.
Next, the error correction preprocessing unit 300 determines whether or not the beacon signal information received from the plurality of beacons 10 by the terminal 30

) Can be used to correct the supplemented beacon signal information.
More specifically, the error correction preprocessing unit 300 determines whether or not the beacon signal information received from the plurality of beacons 10

) And the supplementary beacon signal information (

) To calculate the first correction beacon signal information (

At the third time, the beacon signal information received from the plurality of beacons by the terminal

) And the first correction beacon signal information (

) To calculate second correction beacon signal information (

Can be derived. At this time, the second viewpoint may be a specific cycle-1 time point of a plurality of beacons 10 that periodically transmit beacon signal information, and the third viewpoint may be a time point of a plurality of beacons 20 that periodically transmit beacon signal information And may be a specific cycle-2 time point. At the second time, the terminal 30 transmits beacon signal information ("

And the beacon signal information received from the plurality of beacons by the terminal at a third time

) May be a reference value stored in the database 100.
Referring to FIG. 4, the beacon signal information correction step of the present invention will be described. In the beacon signal information correction step,

) 630 and the second time point

The beacon signal information received from the plurality of beacons by the terminal

) 640 to obtain first correction beacon signal information (

) ≪ / RTI > At this time, the first correction beacon signal information (

) 650 is expressed by Equation (1). &Quot; (1) "

Next, the error correction preprocessing unit 300 outputs the first correction beacon signal information (

) 650 and the beacon signal information received from the plurality of beacons 10 by the terminal 30 at the third time point

) 660 to calculate second correction beacon signal information (

) ≪ / RTI > At this time, the second correction beacon signal information (

) Is an equation (2). &Quot; (2) "

In this way, the error compensating pre-processing unit 300 obtains the optimal beacon signal information that can determine the position information of the terminal 30 through preprocessing the position check request. In one embodiment, the error correction preprocessing unit 300 performs arithmetic operation by replacing each beacon signal information (received signal strength for each beacon) with an arbitrary sign, and then converts the beacon signal information into beacon signal information. Can be executed.
When the operation of the error compensating unit 300 is completed, the preprocessed signal (

Is transmitted to the control unit 200 which determines or calculates the position of the terminal 30 accurately according to the positional information calculation algorithm. A conventional position calculation method based on the reference beacon signal information for each reference position (received signal strength of beacons collected from a plurality of beacons) can be utilized as the position information calculation algorithm. The control unit 200 can calculate the position of the terminal 30 using the preprocessed beacon signal information and the beacon signal information at the reference position. More specifically, according to the position calculation algorithm, the reference beacon signal information stored in the database 100 and the preprocessed signal

) To determine the position of the terminal 30. For example, referring to Figure 4,

The beacon signal information 670 is most similar to the beacon signal information 610 of the reference position 4 stored in the database 100, so that it can be confirmed that the beacon signal information 670 is located at the reference position 4 (680). The position information calculated through the position calculation algorithm in the controller 200 is transmitted to the terminal so that the terminal can confirm the position (500).

In another embodiment, when the beacon signal information included in the position confirmation request is different from the reference beacon signal information, the terminal uses the beacon signal information received from the plurality of beacons at a time different from the first time point, It is possible to correct the included beacon signal information.
More specifically, the positioning request, that is, the beacon signal information at the first time point

) With reference to the reference beacon signal information,

) To compensate for the missing beacon signal information,

(F140). In addition, the missing beacon signal information supplementing step (F140) may include searching the database for a reference reference location having beacon signal information corresponding to the beacon signal information included in the location confirmation request, And inputting the received signal strength of the first beacon included in the beacon signal information of the reference reference position to the received signal strength.
