Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following description and the accompanying drawings, substantially the same components are denoted by the same reference numerals, and redundant description will be omitted. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 shows a configuration of an emergency call system according to an embodiment of the present invention.

The emergency call system according to the present embodiment includes a plurality of beacons 100_1, 2, ... installed around a traffic passage, a portable terminal 200 of the user 210, a control server 300 provided in the control center 300, A beacon-position information database 320, and the like.

Each of the plurality of beacons 100_1, 2, ... periodically broadcasts a beacon signal including the corresponding beacon identification information. Broadcasting of the beacon signal can use short-range wireless communication. As the short-range wireless communication method, for example, Bluetooth, Bluetooth low energy (BLE), Zigbee and the like can be used.

The mobile terminal 200 includes a mobile terminal having a mobile operating system that can be carried by the user 210 and capable of being connected to the Internet and capable of installing various applications (application programs). For example, Tablet PCs and the like.

The portable terminal 200 is provided with an emergency call application for providing an emergency call service according to an embodiment of the present invention. Since the application installed in the mobile terminal 200 substantially controls the mobile terminal 200 by executing various functions provided by the mobile terminal 200, the operation of the mobile terminal 200 described in the present specification is not limited to the emergency call The operation of the emergency call application can be understood as the operation of the portable terminal 200. [

Since the beacon 100 broadcasts a beacon signal using short-range wireless communication, the beacon 100 has coverage that enables the portable terminal 200 to receive the beacon signal. For example, in the case of Bluetooth or low-power Bluetooth, the coverage is within a radius of about 50 m from the beacon 100. Accordingly, for example, as shown in the drawing, the portable terminal 200 within a radius of 50 m from the beacon 100_2 can receive a beacon signal from the beacon 100_2.

The emergency calling application of the mobile terminal 200 outputs an indication through the screen that the beacon signal is received when the beacon signal is received. At this time, together with a display indicating that the beacon signal is received, a button for inputting the emergency call command from the user 210 may be output together.

FIG. 2A shows an example of a display 220 on which a beacon signal is received and a button 230 for inputting an emergency call command on the screen of the mobile terminal 200. The display 220 and the button 230 may be displayed on a part of the screen in a state in which a screen already displayed on the portable terminal 200 (e.g., a main screen or a screen of another application) is displayed. For example, the display 220 and the button 230 may be displayed in a pop-up form on a part of the screen of the portable terminal 200.

Depending on the embodiment, the emergency call command may be received (or alternatively) via the button 230 displayed on the screen, received via the specific push pattern of the button provided in the mobile terminal 200, It can also be input through a specific input pattern on the lock screen.

For example, in many cases, the portable terminal 200 is in a standby state in which the screen is not turned on, so that if the volume button or the home button is pressed quickly five times in the standby state, it can be recognized as an emergency call command.

Alternatively, the portable terminal 200 typically provides the unlocking password input screen or the unlocking pattern input screen on the lock screen, in which a specific number column or a specific pattern for the emergency call command is set, A specific number column may be inputted or an emergency call command may be recognized if a specific pattern is input on the unlock pattern input screen.

The safety distance that users can feel from conventional CCTV is only 15m, which is the visibility distance for CCTV. However, according to the embodiment of the present invention, when the beacon 100 is within about 50 m from the user 210, for example, the user 210 can recognize that the beacon 100 exists in the vicinity, . In addition, about 1/15 of the cost of installing one CCTV can be installed in one beacon, which can greatly reduce the cost.

The intensity of the beacon signal received by the portable terminal 200 varies depending on the distance from the beacon 100. Generally, the greater the distance, the weaker the intensity of the signal, have. Thus, the emergency calling application can output an indication corresponding to the intensity of the beacon signal when outputting an indication that the beacon signal is received. For example, as shown in FIG. 2B, the display 220 may be different according to the intensity of the beacon signal. Further, the emergency calling application may calculate and indicate the distance from the beacon 100 to the beacon 100 (the distance from the beacon of the strongest signal when a signal is received from two or more beacons) from the intensity of the beacon signal.

The user 210 touches (or double-touches or slide-touches) the button 230 displayed on the screen of the portable terminal 200 or displays a button provided on the portable terminal 200 You can enter an emergency call command by pressing a specific number of times quickly, or by entering a specific number column or a specific pattern on the lock screen. When the emergency call command is input, the emergency calling application transmits an emergency call signal including the received beacon identification information to the control server 310 of the control center 300 through a wireless communication network (e.g., 3G network, 4G network) .

The emergency call application may receive the emergency call command from the user 210 by providing the above described input methods for the emergency call button or the emergency call command even if the beacon signal is not received. When the emergency call command is input when the beacon signal is not received, the emergency calling application transmits an emergency call signal including location information basically grasped in the portable terminal 200, for example, To the server (310).

The beacon-position information database 320 stores beacon identification information of the beacons 100_1, 2, ... and position information of the corresponding beacon. When the emergency call signal including the beacon identification information is received from the portable terminal 200, the control server 310 inquires the received beacon identification information from the beacon-position information database 320 to determine whether the user of the portable terminal 200 210 can be grasped. If the coverage of the beacon is 50 m in radius, the positioning accuracy can also be located very precisely at a radius of 50 m.

The control server 310 can obtain the position of the user 210 of the mobile terminal 200 with the position information that is basically grasped by the mobile terminal 200 from the mobile terminal 200. [ However, in general, the error of the position information detected through the GPS or the base station is relatively large and in some cases, the error may increase to 200 ~ 300m in a dense area such as a building. Accordingly, when the beacon identification information is received from the portable terminal 200, the control server 310 can more accurately grasp the position of the user 210 using the beacon identification information.

According to the embodiment, when the emergency calling application transmits location information, which is not recognized by the beacon signal, to the control server 310, the beacon identification information received within a predetermined time (e.g., 10 minutes) And stores the beacon identification information and the reception time together with the emergency call signal.

By doing so, the control server 310 determines the position of the user 210 by using the position information at the reception time point of the beacon signal, which is grasped by using the beacon identification information, It is possible to grasp accurately. For example, if the position information detected by the portable terminal 200 is very distant from the position immediately before receiving the beacon signal, the position of the user 210 can be more accurately estimated You can do it.

The control server 310 controls the monitoring monitor 330 so that the monitoring person 350 can confirm the location of the user 210 that has been detected using the beacon identification information included in the emergency call signal or the location information of the mobile terminal 200 . Then, the control officer 350 may take measures such as dispatching the police station or the personnel at the nearest station from the location of the user 210, and so forth.

Also, the emergency calling application can display the location where the beacons 100_1, 2, ... are installed and the coverage of each beacon on the electronic map. The user 210 (particularly in the case of a woman, a senior citizen or a late-night walker) confirms the location and coverage of the beacons 100_1, 2, By choosing the route around you, you will be able to travel on a more relaxed route.

Further, the emergency call application may recommend a path that overlaps most with the coverage of each beacon among a plurality of possible paths, when providing the path from a specific origin to a specific destination on an electronic map.

For example, as shown in FIG. 3, when a route from the source S to the destination D is searched, a plurality of routes are searched within a predetermined distance, and a path P, which overlaps the coverage of the beacons, can do. For example, if the user 210 is a female, an elderly person, or a late-night walker, the emergency call application will select a secure path to travel, even if it is slightly faster than the fastest path.

In addition, the emergency calling application periodically (or periodically stores the beacon identification information received from the mobile terminal 200 or the beacon identification information received from the portable terminal 200) is transmitted to the control server 310 .

Then, the control server 310 grasps the positions of various portable terminals 200 using the position information or the beacon identification information received from the various portable terminals 200, accumulates the positions to be grasped, It can be displayed on the map together and output through the control monitor 330. [ This allows the operator of the emergency call system to easily plan the installation and supplementation of the beacon by comparing the location where the beacons are currently installed and the places where people are frequently traveling.

FIG. 4 shows a screen displaying the accumulated positions of the various mobile terminals 200 and the location and coverage of the beacons on the map through the control monitor 330.

Referring to FIG. 4, it can be confirmed that beacons are not installed in an area indicated by an ellipse in the center, but it is a place where people have a lot of traffic, so that beacons are additionally installed in the area.

Some beacons among the beacons 100_1, 2, ... may be connected to the control center 300 via the emergency call button and the control terminal 340 to transmit the emergency call signal to the control server 310. [ A communication device for communicating with the controller 350 of the mobile communication terminal 300 can be installed together.

FIG. 5A shows an example of a beacon 100_A in which an emergency call button and a communication device are not installed. FIG. 5B shows an example of a beacon 100_B in which an emergency call button 110 and a communication device 120 are installed together. A user who does not have a portable terminal or a user who does not install an emergency call application in a portable terminal can not make an emergency call to the control center 300 using the beacon 100_B installed together with the emergency call button 110 and the communication device 120 And can communicate with the control center 300. VoIP whose QoS is guaranteed can be used for communication between the communication device 120 and the control terminal 340.
