Description

(Exhibition Guide Information Providing System Basesd Positional Information Of Beacon)

The present invention relates to an exhibition information providing system based on location tracking and a user terminal used therein. More specifically, the present invention relates to a system and method for providing exhibition information on the basis of location information The present invention relates to an exhibition information providing system based on location tracking and a user terminal used therefor.

 Currently, the way of operation of the exhibition hall is to receive information by the guidance of the visitor when the visitor visits, to provide voice guidance by utilizing the sensor at a specific location, or to install the unmanned information transmitting device such as a kiosk in a specific location .

Such an operation method is inefficient because information is transmitted to an unspecified number of visitors, and a cost burden is incurred in order to efficiently utilize the unmanned information transmission device.

For example, Patent Document 10-0531599 discloses an automatic guidance system including an RFID code transmitter and a guidance terminal. Although the information terminal of the registered patent can receive the exhibition information without the assistance of the guide, the supply and management of the information terminal is troublesome and requires a considerable cost.

In order to solve the problem of the guide terminal, a system for providing exhibition viewing information using a smart phone is being developed. For example, Korean Patent Laid-Open Publication No. 10-2012-0113053 includes an exhibition management system that provides exhibition information according to location information through information sharing with a user terminal. However, (Bluetooth to Wi-Fi conversion). In order to calculate the position of each user terminal by the triangulation method, a separate expensive server must be built in each exhibition.

The present invention provides an exhibition information providing system that can provide an exhibit located nearest to a user terminal in real time in accordance with a user's position change without using a beacon triangulation method.

The present invention provides a system for providing information on an exhibit located nearest to a user terminal by minimizing a space discrimination error of a beacon.

The present invention provides a system that can provide exhibit information desired by a user even in an exhibition where exhibits are dense enough to discriminate a space of beacons.

Referring to FIGS. 1 and 2, the exhibition information providing system of the present invention includes a user terminal 100 having a display guide application and a beacon 200.

The term used in the present invention is used to mean an art work displayed on an exhibition hall, a thing displayed for sale (for example, a used car). Hereinafter, the present invention assumes that the exhibition is a display work for the convenience of explanation.

The present invention uses a Bluetooth beacon as an indoor distance measuring device with a user terminal. Bluetooth beacons can receive exhibit information even if the distance between the beacons is several tens of centimeters to a few meters. In contrast, NFC and RFID are generally known to be available only within a few tens of centimeters. In addition, Bluetooth has the advantage that it does not have to be brought close to a reader like a NFC or RFID tag.

The beacon 200 refers to a device that periodically transmits a beacon signal for a normal beacon service. At this time, the beacon signal may include beacon identification information such as identification information or position information allocated to the beacon 200, and the beacon identification information is a criterion on which the user terminal 100 is provided with the beacon service.

The user terminal 100 of the present invention refers to a user apparatus capable of transmitting and receiving various data via a communication network according to a user's operation. The user terminal 100 can perform voice or data communication through a communication network (3G, Wi-Fi, 4G, etc.), transmit and receive information through the exhibition information server 300 and a communication network, Lt; RTI ID = 0.0 > beacon-based < / RTI >

To this end, the user terminal 100 of the present invention may include a memory for storing programs and protocols for sending and receiving beacon signals, a microprocessor for executing and controlling various programs, and the like.

The user terminal 100 can access the application providing apparatus connected to the communication network, for example, an application store, and download the exhibition guide application from the application store.

3, the user terminal 100 of the present invention includes a communication module 110, a DB 120, a control module 130, an input module 140, and an output module 150.

The communication module 110 receives beacon signals periodically transmitted from one or more beacons attached to a plurality of exhibits.

The DB 120 stores information of an exhibit. The control module can update the information of the exhibit through the Internet network from the exhibit information server 300. The information of the exhibition may be an exhibition provided by the exhibition information providing system (including the exhibition guide application) of the present invention, an exhibition contents currently being serviced, a guide explanation of each exhibition, and the like.

The control module 130 calculates distances to the beacons based on the received beacon received signal strengths, determines beacons located at the closest distance, and transmits the beacon- And outputs it.

The input module 140 may include at least one of a keypad and a touchpad that generates an input signal according to a user's touch or operation. At this time, the input module 140 may be configured in the form of a touch panel (or a touch screen) together with the output module 150 to simultaneously perform input and display functions.

Generally, triangulation is used to measure the location of a user by a beacon. The position measurement method using the triangulation method calculates the position of the user terminal in the server using the intensity of signal strength from the user terminal received from three beacons installed at different positions.

As mentioned above, the triangulation method requires a separate server (receiving signal information from a beacon) to be provided at each workplace, a sale place, an exhibition hall, etc., and when an error occurs in any one of a plurality of beacon sensors Position measurement itself is difficult.

The present invention can measure and provide a distance to an exhibition object with high accuracy without building a separate server in each exhibition hall.

As shown in FIGS. 1 and 2, the present invention provides a plurality of beacons in each exhibit. Preferably, three beacons can be placed on the same surface in one exhibit. That is, the present invention allows three beacons to be adjacent to each other or to be attached within a few centimeters of the display front part.

Even in the case of a beacon positioned on the same plane, a difference in intensity of a signal received at a user terminal may occur. For example, if there is a malfunction in one of the beacons, or if the beacon is operating normally, or if there is an obstacle or the battery is running low and the signal strength is decreased, the strength of the received signal strength may be different. In addition, even if a normal beacon is used, the signal intensity generated in one beacon periodically changes. Therefore, even if the position is calculated as shown in Equation 1, the position value varies in a predetermined range with time.

Referring to FIG. 3, the control module 130 unifies the identification numbers of a plurality of beacons installed in one exhibit into one identification number. For example, the control module unifies the identification numbers of the three beacons (beacon 1, beacon 2, and beacon 3) installed in the display 1 into one, or assigns the same identification number. In addition, the control module can unify the identification numbers of the major ends of the beacon while maintaining the hardware unique identification number of the beacon as it is.

The control module 130 reads the beacon signal strength received at a predetermined time interval in the communication module 110 and excludes the received signal strength corresponding to the maximum value and the minimum value for each identification number.

For example, two beacons per second (500 ms) are transmitted from three beacons installed in one exhibit (a total of six signals per second are transmitted from one identification number), and the communication module receives a beacon All received signals are received. The control unit excludes received signal strengths corresponding to the maximum value and the minimum value according to the beacon identification number.

The control module may calculate the distance between the beacon and the user terminal using a known received signal strength (RSSI). The formula of Friis can be used as shown in Equation (1).

In Equation (1), L is the measured distance between the user terminal and the beacon,? Is the wavelength of the radio wave, and d is the RSSI.

The control module 130 calculates a distance L (L1, L2, L3, and L4 in the case of distance measurement for four signals) measured by the identification number of the beacon and calculates an average distance Lm between them L1 + L2 + L3 + L4) / 4).

The control module may list the average distance for all the identification numbers received as shown in FIG.

Meanwhile, the control module may discard the highest minimum among six received signal strengths (RSSIs) received from three beacons installed in one exhibit, and then calculate the average received signal strength of the remaining four average values have. The controller may calculate the average distance using Equation (1) and the average received signal strength.

Meanwhile, the control module 130 calculates each distance value using Equation (1) for six received signal strengths (RSSIs) received from three beacons installed in one exhibit. The average distance value of the remaining values excluding the maximum minimum distance value among the calculated six distance values can be calculated.

As shown in FIG. 4, the control module first determines whether there are two or more identification numbers indicating a minimum average distance value (minimum average distance).

When the identification number indicating the minimum average distance is one, the control module receives the exhibit (exhibit product) information corresponding to the minimum identification number from the DB 120 and outputs it as an application execution screen and voice (sound source) (See FIG. 7). Also, the control module can display a list according to the average distance order on the application execution screen. For example, the control unit may display information on an exhibit currently being output at the top of the application execution screen, and may display a list (exhibit name, artist, etc.) of exhibits corresponding to the second to fifth average distances at the bottom .

The control module can output all of the exhibits (exhibition works) information to the application execution screen when the identification number indicating the minimum average distance is two or more.

The control module may provide a user interface so that a user (a viewer) can select any one of a plurality of pieces of exhibit (exhibition) information output on the application execution screen.

For example, the control module lists a plurality of exhibits (minimum average distance) on the application execution screen and displays them on the screen, and when any one of them is clicked, Screen and audio (sound source) can be output. In addition, the control module may display a list according to the average distance order at the bottom of the application execution screen. For example, the control unit may display information on an exhibit currently being output at the top of the application execution screen, and may display a list (exhibit name, artist, etc.) of exhibits corresponding to the second to fifth average distances at the bottom .

Also, the control module may provide a user interface such as a pop-up exposed at the top of FIG. 7 to guide a user's selection.

The control module calculates an average distance to each identification defense according to the set time (several seconds to several minutes), updates the distance for each exhibition on the basis of the calculated average distance, and displays the updated distance on the application execution screen. In other words, the control module can update the average distance list of FIG. 6 by a set time, for example, from once every second to every ten seconds.

As compared with the method of calculating the location of each user terminal in the server using the triangulation method and providing the exhibition information to each user terminal in the server using the triangulation method, Exhibits can be provided. In addition, since the present invention utilizes three beacons (coplanar) installed in one exhibit to measure distances based on an average value of beacon signal intensities, compared with the case of using one beacon, The error of the distance measurement can be reduced to a considerable extent.

In the present invention, a list of a plurality of exhibits and a list of exhibit information such as a distance of a visitor (user) is updated on the terminal screen in real time according to a change of a user's location, and exhibits displayed within 1.5 m, The user can select a desired exhibition and receive information.

Meanwhile, the system of the present invention includes a QR code installed on an exhibit, and recognizes a QR code as a smart terminal for exhibits exhibited within 1.5 m, which is difficult to discriminate a beacon space, and can receive exhibit information.

 Meanwhile, the control module may record the output time of each exhibit output through the output module according to time and store the same in the DB. For example, the control module can record the output time according to time as shown in Table 1 below.

time object Time of visit 10: 10-10: 12: 00 Exhibit A 2 minutes 10: 12: 01-10: 15: 30 Exhibit B 3 minutes 30 seconds 10: 15: 31-10: 20: 20 No output Judging as moving (no output for adjacent exhibits C, D, E) 10: 20: 21-10: 25: 10 Exhibit G 4 minutes 49 seconds 10: 25: 11-10: 27: 02 Exhibit F 1 minute 09 second 10: 27: 03-10: 30: 30 Exhibition H 6 minutes 47 seconds 10: 30: 31-10: 33: 50 No output Judging as an additional appreciation of exhibit H (included in H time) 10: 33: 51 ~ 10: 36: 20 Exhibit J 2 minutes 29 seconds 10: 36: 21-10: 40: 40 Exhibition K 4 minutes 19 seconds 10: 40: 41-10: 44: 14 Exhibit L 3 minutes 33 seconds 10: 44: 15-10: 48: 05 No output Judged as moving (no output for adjacent exhibit M) 10: 48: 06-10: 52: 25 Exhibit N 4 minutes 19 seconds 10: 52: 26-10: 55: 35 Exhibition P 3 minutes 09 seconds 10: 55: 36-10: 57: 55 Exhibit Q 2 minutes 19 seconds 10: 57: 56 ~ No output Excluded from exhibition time because it is suspended

The control module may record and transmit a time line according to exhibits of user terminals in the room. For example, referring to Table 1, a specific user terminal views exhibits in the order of A, B, G, F, H, J, K, L, N, P, O information is not output. Also, it can be seen that the user terminal took the most time with respect to the exhibit H, followed by G and K (N).

Meanwhile, the terminal or system of the present invention includes an augmented reality (AR) algorithm, so that virtual 2D to 3D images or holograms can be projected on the periphery of the exhibition. For example, the control unit of the present invention can output the artist image of the corresponding exhibit to the application execution screen in 3D form when outputting the exhibit information providing output. By displaying the 3D artist image on the screen rather than providing simple text information, it is possible to increase the concentration of the exhibition description.
