Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a beacon position search method using a single terminal,

The present invention relates to a beacon position search method and apparatus using a single terminal, and more particularly, to a beacon position search method and apparatus using a single terminal, in which a relative positional shift amount and a relative directional angle between each of three landmark points are detected by user movement to three different landmark points, And more particularly, to a beacon position search method and apparatus using a single terminal that can accurately calculate a position and a direction of a beacon through distance detection between a point and a beacon.

As is well known, efforts to solve the problem of locating objects have been made for a long time. The problem of locating such a location has become increasingly more useful in modern times. Especially, in the ubiquitous era, it is expected that it will evolve into an era where people can communicate with each other and communicate anytime and anywhere. Among the basic technologies that become the driving force of this era, the location recognition technology includes robot control, disaster, military, It will occupy an important position such that it can not find an unused field.

Conventionally, the conventional position estimation technique, which is attempted to be applied to navigation and aviation technologies, has been actively studied with a focus on the object position estimation in a computing environment along with the development of mobile computing technology in recent years. This location estimation technology is widely used in patients, robots, personnel management in hospitals, industrial sites, etc., as well as in life sciences and military operations where visibility is not secured.

Recently, various technologies have been applied to identify their own locations in portable terminals that are usually held by the general public. These mobile terminals periodically communicate with a base station in a cell in which they are located to confirm their location and receive a call service. Unlike a conventional position estimating apparatus, devices that can be used on the move, such as a portable terminal, are characterized in that their positions are not fixed. Therefore, various technical means for position estimation are needed.

Most of these position estimation techniques are techniques for estimating the position of a desired object based on an absolute reference position. In many cases, a fixed absolute reference position is an indicator.

For example, a position estimation technique using GPS is a technique for estimating a position of a mobile terminal through at least three GPS satellites whose absolute coordinates are known.

There is also a technique of estimating a position of a mobile terminal using at least three mobile communication base stations whose absolute coordinates are known, using a position estimation technique using a mobile communication base station. However, in the triangulation method using the communication base stations, the distance from 200 to 300 meters is large when the error is large.

On the other hand, there is a location estimation technique using a local communication means such as a beacon or an RFID, and a local communication means such as a beacon or an RFID, which registers a unique identification code matching a specific address in a server, Is a technology that allows a remote server to know where a corresponding mobile terminal is located.

However, this technique is also a technique for estimating a position by matching the position of a short distance communication means such as a beacon or an RFID to a unique coordinate of a specific address.

The problem is that if the exact position of the beacon is not known, it can only estimate the distance through the signal strength of the beacon in finding the beacon, but it is difficult to grasp the position because it does not know the direction.

In particular, recently, a technique of finding a valuable item through a local communication network by attaching a small beacon to a valuable item has been developed. However, since the exact beacon position can not be known even in this case, I can not help but wander around there and find the valuables.

However, in this case, there is a problem that it takes too much time to locate the object, and in the case of the store, it disturbs other customers.

In addition, there is a method for finding a beacon in addition to the above method. For example, there is a method of generating a buzzer sound to indicate a position of the beacon itself. However, this method has a problem in that there is a possibility And there were additional problems such as battery consumption of the beacon.

FIG.

The beacon position search apparatus 2 using a single terminal according to an exemplary embodiment of the present invention can search for a beacon position using an application installed in a mobile communication terminal, The beacon position and direction can be accurately calculated by detecting the shift amount and the relative direction angle and comparing the electric field intensity with respect to the beacon by converting the distance to the distance.

The beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention refers to all the terminals on which the beacon position search application 10 is mounted and the beacon position search apparatus 2 using a single terminal, Portable terminals including portable PCs and smart phones are generally included.

More specifically, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention is an apparatus that can accurately detect the location of a beacon by receiving a short distance wireless signal from a beacon .

To this end, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention is a portable wireless terminal having a beacon position search application 10 installed therein.

Specifically, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention receives a radio signal from the beacon 50, converts the intensity of the signal into a distance, The user moves to the second marking point (2) and the third marking point (3) at different positions with reference to the first marking point (1) determined by the key signal and the first, second and third marking points (1, 2, 3) and the distance between the first, second and third marking points (1, 2, 3) and the beacon (50) The application 10 is an apparatus installed inside.

At this time, the beacon 50 may be attached to an expensive or valuable article such as a precious metal or a luxury bag, a car, a carrier, a travel bag, a briefcase, a notebook, a smart phone, a bicycle, a pet, You can find it exactly.

In this case, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention includes an acceleration sensor (not shown) for detecting a movement distance between the first, second, and third landmark points (1, 2, The acceleration sensor 18 can detect the number of steps of the walk through the vibration caused by the movement of the user.

Therefore, if the user sets the length of one beam in the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention, it is confirmed how many beams are applied using the acceleration sensor 18, Can be converted into a length to calculate the moving distance.

In general, the length of one beam is similar to the length of one beam of a user having similar height. Therefore, when the acceleration sensor 18 detects how many beams have been moved by applying the average length (statistical average length) of one beam per each height The moving distance can be calculated.

To this end, the present invention requires input of the user's elongation, but since the weight and elongation are generally correlated, it is also possible to estimate the average elongation by inputting the weight and to estimate the average length of one elongation according to the elongation .

On the other hand, at the initial setting of the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention, the length of one beam is actually measured and input by using a distance equal to a scale, Since the personalized travel distance can be calculated, the method is most accurate, but using the statistical average does not cause a large error.

Also, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention includes a geomagnetism sensor (not shown) for detecting a direction angle between the first, second, and third landmark points (1, 2, The geomagnetic sensor 20 is a sensor for detecting a direction angle corresponding to the user's rotation at the first, second and third landmarks (①, ②, ③).

More specifically, the geomagnetic sensor 20 is used to measure the magnetic north of the earth, and the result is provided as an electronic numerical value. The geomagnetic sensor 20 has a very fine resolution. Therefore, by using such a geomagnetic sensor 20, it is possible to obtain an accurate numerical value that the moving object is aiming at, and thus the direction angle between the first, second and third landmark points (①, ②, ③) Can be obtained.

Preferably, in order to obtain a direction angle between the first, second, and third landmark points (1, 2, 3) through the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention, The first marking point (①) should be moved. Then, the geomagnetism sensor 20 can calculate the direction angle of the second landmark point (2) with respect to the first landmark point (1).

Preferably, when the first, second and third marking points (①, ②, ③) are caught by movement of the user, the directional angle between the first, second and third marking points (①, ②, ③) It may be difficult to estimate the position of the beacon 50. Therefore, the direction angle of the second marking point (2) with respect to the first marking point (1) and the direction angle of the third marking point (2) with respect to the second marking point (③) should be more than 30 degrees.

Therefore, the user inputs the first marking point (1) to the beacon position search device (2) in order to make a point as a first marking point (1), moves by a certain length in a certain direction, (2)), the direction angle and the moving distance of the second landmark point (2) with respect to the first landmark point (1) can be calculated and the position can be displayed on the screen.

If the beacon position search apparatus 2 inputs a third mark point (3) to the beacon position search apparatus 2 from the second mark point (2) in a predetermined direction and a predetermined length, The direction angle and the moving distance of the third landmark point (3) with respect to the two landmark points (2) can be calculated and the position can be displayed on the screen as shown in FIG.

Meanwhile, the beacon position search application 10 installed in the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention can search for the first, second and third landmark points (1, 2, 3) When the setting signal is applied, the wireless signal is received from the beacon 50 to detect a separation distance to the first, second, and third marking points (①, ②, ③).

At this time, the short range wireless signal is a Bluetooth signal or an RFID signal.

On the other hand, if more marker points are added in addition to the first, second, and third marker points (1, 2, 3), the position of the beacon 50 can be estimated more accurately.

There are various known techniques for calculating the distance from the beacon 50, which generates a short distance wireless signal, at a predetermined distance.

The beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention can calculate the distance between the first, second and third landmark points (?,?,?) And the beacon 50, It is calculated using a variety of well-known techniques.

That is, a method of measuring a distance of at least one of a time of arrival (TOA) of a signal, a time difference of arrival (TDOA), or a received signal strength indicator (RSSI) The distance between the beacon position search device 2 and the beacon 50 can be calculated.

As shown in FIG. 3, in theory, the intensity of the signal is inversely proportional to the distance. If a signal propagation model reflecting the intensity of the signal is established, the signal intensity can be converted into a distance. The transmitting node transmits the signal with a certain intensity and measures the distance using the intensity of the attenuated signal at the receiving node. That is, the natural phenomenon is that the signal strength decreases as the distance from the transmitting node to the receiving node increases. A more practical implementation method is beyond the essence of the present invention and can be grasped by a person having ordinary skill in the art to which the present invention belongs.

However, in the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention, distance values matching with the strength of a certain radio signal are stored in advance as shown in FIG. 3 through a known technology, The distance-converted information storage unit 26 stores the distance-converted information.

Therefore, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention can detect the beacon position of the radio signal received from the beacon 50 at each of the first, second, and third landmark points (1, 2, 3) It is possible to determine how far the first, second and third marking points (①, ②, ③) are separated from the beacon 50 by using the intensity of the beacon 50. [

At this time, it is not possible to display the position of the beacon 50 on the screen based on only one marking point and only the separation distance from the beacon 50.

That is, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention includes first, second, and third landmark points (1, 2, 3) ), And by converting the radio signal strength of the beacon 50 from the first, second and third marking points (①, ②, ③) into the separation distance, the first, second and third marking points (①, ② , ≪ / RTI > < RTI ID = 0.0 > 3). ≪ / RTI >

4 is a block diagram illustrating a beacon position search apparatus using a single terminal according to an embodiment of the present invention.

Referring to FIG. 1, a beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention sets user's body information within the beacon position search apparatus 2, and displays first, second, (2), (3)).

Also, a beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention includes a wireless signal receiving unit 14 for receiving a wireless signal from the beacon 50 therein; A voltage detector (16) for detecting a voltage through a radio signal applied from the radio signal receiver (14); A distance conversion information storage unit 26 for extracting a distance value matched with the voltage detected by the voltage detection unit 16 is constructed.

In addition, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention includes information about the first landmark point (1) and information about the second landmark point (1) A landmark point information storage section 24 for storing information on the landmark point 2 and information on a third landmark point 3 with respect to the second landmark point 2; And a user's body information storage unit 22 for storing the height, weight, and stride information of the user who has an influence.

Meanwhile, the beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention may include a beacon position search apparatus 2 having a beacon position search apparatus 2, And calculates the moving distance and the direction angle between the first, second and third marking points (①, ②, ③) and outputs the first, second and third marking points (①, ②, ③) to the display unit (30) And the position of the beacon 50 and the current position information of the beacon 50 on the screen.

Preferably, the control unit 32 sets the first, second, and third marking points (①, ②, ③) so that the user can set the first, second, and third marking points (①, ②, (1), (2), and (3)) and the beacon (50) is displayed, the direction toward the beacon (50) The position information of the current user with respect to the position of the user 50 is stored.

If the control unit 32 is set to compensate the error value by comparing the movement distance of the actual user with the movement distance calculated using the acceleration sensor 18 in cooperation with the user's body information storage unit 22, And the movement distance is calculated by automatically reflecting the compensation set value.

That is, a user with a height of 180 centimeters entered the body information, and the average stride of people with 180 centimeters was previously stored as 60 centimeters. However, as a result of the user actually moving five steps, If the measured value is not 300 centimeters but is 250 centimeters, the user can know that the movement distance per user is 50 centimeters. Therefore, the user can directly access the beacon position search apparatus using a single terminal according to the embodiment of the present invention. It is also possible to set the transfer moving length of 50 centimeters.

FIG. 6 is a diagram illustrating a screen configuration of a beacon position search apparatus using a single terminal according to an embodiment of the present invention. Fig.

The beacon position search apparatus 2 using a single terminal according to an embodiment of the present invention may be provided with a beacon position search apparatus 2 for receiving beacons 50 from the beacons 50 at the first, It is possible to determine how far the first, second and third marking points (①, ②, ③) are spaced from the beacon 50 by using the intensity of the radio signal.

5, if the beacon position search apparatus 2 knows only a distance from the beacon 50 based on any one of the landmark points (for example, the first landmark point (1)), Is a circle centered on the first marking point (①) and having the distance of the distance as a radius.

In this case, since the beacon 50 can be located anywhere on the circumference, the user can not search for the location of the beacon 50 only once.

In this state, when the user moves and sets the second marking point (2), the position of the second marking point (2) is relatively displayed on the screen based on the first marking point (1) Similarly, if the distance between the two marking points (②) and the beacon (50) is known, the distance between the second marking point (2) and the corresponding distance from the beacon (50) A circle with a radius is displayed.

In this case, since the beacon 50 may be positioned on the circumference centered on the first landmark point (1) and on the circumference centered on the second landmark point (2), two beacons 50 It can be seen that any one of the points is the location of the beacon 50. [

Accordingly, at least three landmark points are required to accurately locate the beacon 50 with respect to the first, second, and third landmark points (①, ②, ③).
