Description

TECHNICAL FIELD [0001] The present invention relates to a method for tracking lost property using a beacon and a mobile terminal,

The present invention uses a beacon (10) for delivering a Bluetooth or ZigBee based low power short range wireless signal and a mobile terminal (20) for sensing a beacon (10) transmission signal to locate the lost or stolen article or child The mobile terminal 20 detects an unspecified number of signals transmitted from the beacon 10 attached to the lost property and the application installed in the mobile terminal 20 is detected by the management server 40. [ So that it is possible to grasp the position of the lost or lost item attached to the beacon 10 or the like.

The beacon 10 is a device for periodically transmitting a radio signal. The beacon 10 is a device for transmitting a radio signal such as a Bluetooth and a Zigbee, , It is used in various fields such as production automation, traffic and logistics.

In particular, recently developed BLE (Bluetooth Low Energy) -based wireless module 11 has very little power consumption and can send signals to the power source 13 for several years or more. By applying it to the beacon 10, It is possible to downsize the beacon 10 with the built-in beacon 10, thereby overcoming the time and space limitation of the operation of the beacon 10.

An example of the application of such a beacon 10 is a bicycle theft prevention technique. The bicycle 10 is equipped with a beacon 10, a motion sensor, and a device capable of discriminating theft of the bicycle. A beacon 10 connected to the sensor transmits a theft signal, and a stationary receiver is installed in a place where bicycle traffic is frequent, such as a bicycle shop, a repair shop, a bicycle-only road and a park, Patent No. 976844 can be mentioned.

In the conventional beacon 10 lost-item tracking technology including the patent No. 976844, whether the lost or stolen item is lost or not is determined through means mounted on the tracked object itself such as a motion sensor, so that the beacon 10 is activated, And receives the theft signal transmitted from the beacon 10 via the fixed receiver.

First, it is determined whether a lost or stolen object is detected by a theft detection means such as a motion sensor mounted on the product itself. In this case, there is a possibility that a malfunction may occur and a user must set the detection state of the motion sensor from time to time there was.

That is, when the goods are moved by the owner, the beacon 10 is kept in the inactive state and the beacon 10 should be set to operate only when it is moved by theft, so that the operation state of the theft / Normal operation is possible only if the user sets it from time to time.

The conventional beacon 10 loss prevention technique is a method of receiving signals of the beacon 10 through a stationary receiver installed at a retail store, a repair shop, a public place, or the like of a corresponding article, The receivable area of the signal is extremely limited, and therefore there is a problem that it is almost impossible to grasp the actual position of the lost article.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows an apparatus such as a beacon 10, a mobile terminal 20, a user terminal 21, and a management server 40 and a connection state between these apparatuses, which perform the present invention. As shown in the figure, A beacon 10 for periodically transmitting a radio signal is attached to the item to be tracked and an application for receiving a transmission signal of the beacon 10 is mounted on a plurality of mobile terminals 20 capable of being connected to the radio network 30 .

In the present invention, as items to be tracked, all movable items such as a bag or the like as illustrated in Fig. 1, transportation means such as a bicycle or an automobile, or portable electronic apparatus such as a notebook computer can be applied, Or pets may also be applied.

A beacon 10 applied to the present invention is a compact device having a built-in wireless module 11 for performing low-power short-range wireless communication such as Bluetooth and Zigbee. The beacon 10 includes a block diagram of an extractor- A microcontroller unit (MCU) 12 and a power source 13 for controlling the radio module 11, as shown in FIG. 1, which periodically oscillates a radio signal including unique information.

The radio module 11 applied to the beacon 10 of the present invention is a radio signal oscillator for low power short range wireless communication such as Bluetooth or ZigBee and performs short range communication with a transmission / reception range of about several tens of meters under the condition that power consumption is minimized, Particularly, the recently developed Bluetooth wireless energy (BLE) based wireless module 11 is very small in power consumption, and thus it is possible to transmit a coin cell to a power source 13 over several years.

The MCU 12 included in the beacon 10 is a device for controlling the wireless module 11 and includes a core for performing control operations, a memory as a storage device, and a serial interface as an input / Function.

The beacon 10 can be miniaturized through the wireless module 11 driven by the small power source 13 and the highly integrated MCU 12 and can be easily attached to the tracked object as shown in FIG. The beacon 10 illustrated in the figure is attached in the form of a key ring and bound to a bag as a tracking object. However, the beacon 10 may be put in a bag, or in the case of an article other than a bag, It can also be worn as a necklace for children or pets.

The beacon 10 of the present invention operates independently by the built-in power source 13 and can be operated for a few years without replacement of the power source 13 due to extremely low power consumption as described above. The mounted beacon 10 can be used for a long period of time without additional maintenance, thereby ensuring user convenience.

The radio module 11 embedded in the beacon 10 of the present invention periodically transmits a certain radio signal under the control of the MCU 12, and the transmitted radio signal includes unique information for specifying the beacon 10 do.

That is, the unique information periodically transmitted from the beacon 10 is information such as a serial number or identification (ID) uniquely assigned to the beacon 10, and is used to distinguish the individual beacons 10, As in wireless devices, a Universal Unique Identifier (UUID) may be included.

The wireless signal including the unique information transmitted from the beacon 10 is received by the mobile terminal 20 and processed by an application installed in the mobile terminal 20. The mobile terminal 20 is a smart phone or a tablet PC As a portable information device, a wireless signal receiving device of the same standard as that of the wireless module 11 of the beacon 10 is incorporated.

That is, when the Bluetooth-based wireless module 11 is applied as the wireless module 11 of the beacon 10, the mobile terminal 20 is also equipped with a Bluetooth receiving function, and a master for transmitting a Bluetooth communication- And the slave receiving the signal are set as the beacon 10 and the mobile terminal 20, respectively.

The present invention is applicable to a mobile terminal 10 such as a smart phone or a tablet PC, which is currently installed, with a Bluetooth reception function, without requiring a separate device to be installed in the mobile terminal 20.

The mobile terminal 20 of the present invention receives the radio signal periodically transmitted from the beacon 10 and accesses the management server 40 through the radio network 30. The reception and management of the beacon 10 signal The connection to the server 40 is performed by an application installed in the mobile terminal 20.

The application is an application program operating in the operating system of the mobile terminal 20. The application processes the received beacon signal to extract the unique information and accesses the management server 40 through the wireless network 30 And transmits the unique information through the wireless network 30 like a normal smartphone application program.

Here, the wireless network 30 is a Wi-Fi (Wireless) network that performs communication based on a conventional mobile communication network such as TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access) (WiBro), WiBro (Wireless Broadband), and long term evolution (LTE). The wireless LAN and the mobile communication network, which are not shown in the figure, constitute a gateway server And a communication service provider server which may be a kind of gateway server.

The management server 40 connected to the wireless network 30 and connected to a plurality of mobile terminals 20 identifies the beacon 10 in the present invention and transmits the beacon 10 transmitted from each mobile terminal 20 ). As shown in FIG. 1, the database 45 is connected to systematically manage beacon 10 related information including the above-described unique information.

The method for tracking lost items according to the present invention is intended to prevent loss and theft of a tracked object. In a specific commercial aspect, a beacon 10 for installing or worn a lost property is manufactured and sold, An independent business method in which a service company operating the server 40 attracts a plurality of tracked object owners or child carers as subscribers and a method of manufacturing and selling a specific product to a buyer of the goods as a part of the customer service And distributes the application and manages the management server 40. [

In addition, the present invention may be performed as a customer service of a telecommunication carrier that has a plurality of mobile terminal users as subscribers. If the tracked object is a hobby article such as a bicycle or a camera, It is also possible for a non-commercial operation in which the applications are purchased jointly and the management server 40 is rented.

The mobile terminal 20 of the present invention is not a mobile terminal 20 of a tracked object owner or protector performing one-to-one communication with a beacon 10 of a specific tracked object, And is defined as an unspecified number of mobile terminals 20 on which an application receiving a beacon 10 signal is mounted.

That is, the present invention is not intended to prevent the loss and theft of the tracked object through communication between the beacon 10 mounted on the tracked object and the mobile terminal 20 such as the smartphone of the owner of the tracked object, The mobile terminal 20 receives an arbitrary beacon 10 signal at an arbitrary position, captures a beacon 10 that transmits double-registered registered unique information, 20 to estimate the position of the tracked object.

Accordingly, in the case of the commercialization mode as described above, in the case of the independent business method, the mobile terminal 20 becomes the mobile terminal 20 of all the lost or misplaced tracking service subscribers, The mobile terminal 20 of the entire purchaser who has purchased the tracking object of the manufacturer or the sales company of the manufacturer or the mobile terminal 20 of the whole communication member company or the mobile terminal 20 20).

The beacon 10 continuously transmits the radio signal including the unique information irrespective of whether the beacon 10 is lost or stolen. The transmission of the radio signal is performed on the premise of the reception of the specific mobile terminal 20 Directional transmission, which is performed periodically so that any mobile terminal 20 can receive it at any time, rather than directional transmission, so that the entire mobile terminal 20 located within the receivable range of the beacon 10 signal has unique information And receives the included radio signal.

In the present invention, reception and processing of the beacon 10 transmission signal is performed by an application installed in the mobile terminal 20, and such an application is also required to always wait for reception of the beacon 10 transmission signal, The mobile terminal 20 operates in a manner that is always executed under the operating system of the mobile terminal 20 regardless of whether the user is conscious or not. As can be seen from the sequential configuration of the present invention to be described later, The main function of the mobile terminal 20 in the normal operation of the application is limited to the relatively simple process of extracting unique information from the received radio signal of the received beacon 10 and transmitting it to the management server 40 The hardware and software erosion of computational resources is negligible.

FIG. 2 illustrates a screen of the mobile terminal 20 in which an application is running. As shown in FIG. 2, the user does not substantially recognize whether or not the application is normally executed. When the user intentionally confirms the execution state of the application A status bar at the top of the screen of the mobile terminal 20 may be dragged so that the base running or functioning function is output.

As shown in FIG. 3, the present invention performed through the above-described components starts with a loss registration step S11 in which the user terminal 21 transmits identification information of a tracked object to the management server 40. FIG.

That is, the owner who knows the lost item of the beacon 10 mounted article connects to the management server 40 with his / her own user terminal 21 and notifies the lost fact. Here, as the user terminal 21, An information device such as a smart phone, a computer or a tablet PC that can be used can be utilized.

The connection of the management server 40 of the user terminal 21 is technically performed by the same or similar route as the connection of the management server 40 of the mobile terminal 20 described above, And the connection of the management server 40 of the user terminal 21 is performed by the owner of the tracked object operating the user terminal 21 by his or her will and the connection of the management server 40 of the mobile terminal 20 (20) is automatically performed by an application installed in the mobile terminal (20) in a situation where the user is not recognized.

Of course, as described above, it is obvious that the owner of the lost property or the guardian of the lost child is also a subscriber of the present invention service, and the owner also has the mobile terminal 20 on which the application is installed. Touch theft report function that notifies the management server 40 of the fact of the loss automatically when the user touches the on-screen icon by using the application in the application, If the owner of the object to be tracked operates the information device such as the smart phone which is the mobile terminal 20 and the user terminal 21 in a single operation, the loss registration step S11 may be performed.

Also, the owner of the lost property can utilize any information device such as a computer or tablet PC capable of accessing the Internet as the user terminal 21 without using the mobile terminal 20 with the application as the user terminal 21, The connection to the management server 40 and the transmission of the identification information may be performed by a method such as accessing a web page connected to the management server 40 through a normal browser without intervention of a specific application ≪ / RTI >

By not specifying the user terminal 21 as the mobile terminal 20 on which the application is installed, it is possible to immediately perform the loss registration step S11 as soon as the owner of the lost property recognizes the loss, Even when the tracked object and the user terminal 21 are lost at the same time as when the bag is lost, it is possible to obtain the advantage that the lost object can be reported quickly.

The identification information transmitted from the user terminal 21 to the management server 40 in the lost registration step S11 is information for specifying the lost tracked object, that is, the beacon 10 mounted on the lost property, And an ID and a password set by the owner of the tracked object at the time of subscription to the service.

FIG. 4 illustrates a process in which a loss registration step S11 or a location notification step S45 to be described later is performed through a dedicated application installed in the user terminal 21, which is a smartphone owned by a lost property owner. The owner of the lost property can touch the icon implemented on the touch screen of the user terminal 21 and input the password so that the loss registration step S11 can be performed.

Since the purpose of performing the loss registration step S11 is to notify the management server 40 of the lost status of the specific tracked object, the management server 40 can obtain the information that can identify the beacon 10 mounted on the tracked object The management server 40 is provided with the beacon 10 based on the unique information of the beacon 10 and the beacon 10 such as the owner ID and password of the tracked object equipped with the beacon 10, The identification information transmitted to the management server 40 in the loss registration step S11 can be selected and applied to one of the various information depending on the situation.

However, since unique information transmitted from the beacon 10 is composed of a complicated character string and a numerical string following UUID (Universal Unique Identifier) as in a conventional wireless device, The ID is replaced with the identification information of the user terminal 21 such as the telephone number provided to the server in the connection process of the wireless network 30 as shown in FIG. 4, The lost registration step S11 may be performed by inputting only the password for the lost password.

When the loss registration step S11 is completed, the management server 40 receives the identification information transmitted from the user terminal 21, connects to the connected database 45, and then transmits the beacon 10 Is set to the lost state and the database updating step S12 for updating the database 45 is performed.

The unique information of the beacon 10 and the identification information of the owner of the tracked object to which the beacon 10 is attached are systematically recorded in the database 45 connected to the management server 40. In accordance with various types of business, Various additional information such as the personal information of the owner of the object, the contact name, the model name of the object to be tracked, and the production year may be recorded. In FIG. 1, the management server 40 and the database 45 are shown as being physically separated. A database 45 may be built in the storage device of the management server 40 for expressing the functions of the components separately.

In the meantime, regardless of whether the loss registration step (S11) to the DB updating step (S12) are performed or not, a beacon (10) mounted on the tracked object periodically transmits a radio signal including unique information Is continuously performed and a signal receiving step S22 in which an unspecified number of mobile terminals 20 located around the beacon 10 receive the unique information transmitted by the beacon 10 is also continuously performed.

When the mobile terminal 20 equipped with the above-described application is present around the beacon 10 periodically transmitting the wireless signal including the unique information, the signal receiving step S22 is performed immediately, and the signal receiving step S22 An information transmission step S23 for transmitting the location information of the mobile terminal 20 and the received unique information to the management server 40 via the radio network 30 after the application installed in the mobile terminal 20 ) Is performed.

That is, in the information transmission step S23, the application installed in the mobile terminal 20 extracts the unique information of the radio signals transmitted by the beacon 10, merges the extracted unique information and the location information of the mobile terminal 20 The location information transmitted together with the unique information is information capable of estimating the location of the mobile terminal 20, and the location information transmitted from the mobile terminal 20 20 are connected to the management server 40 via the communication company operating radio network 30 such as TDMA, CDMA and LTE, the location information calculated through the base station location to which the mobile terminal 20 is connected is applied, When the terminal 20 accesses the management server 40 through the wireless LAN, the access point location of the wireless LAN can be applied.

When a global positioning system (GPS) sensor is mounted on the mobile terminal 20 performing the information transmission step S23, the application may drive the coordinates to transmit the coordinates of the mobile terminal 20 as position information.

The information transmitted from the mobile terminal 20 to the management server 40 in the information transmission step S23 is location information and unique information as described above, As information based on the location, information that can identify the mobile terminal 20 can be completely eliminated technically, and unique information can also be transmitted simply from the beacon 10, It is possible to set no information that can identify the mobile terminal 20 among the information that the management server 40 can acquire through the transmission step S23, It blocks potential exposure and effectively protects your privacy.

A DB inquiry step S31 for inquiring the database 45 using the unique information among the information received from the mobile terminal 20 by the management server 40 when the information transmission step S23 is completed, The location registration step S41 is performed in which the management server 40 stores the location information transmitted together with the unique information in the database 45. [

That is, when the unique information transmitted in the step S23 of carrying out the result of the DB inquiry step S31 matches the unique information registered in the lost state in the lost registration step S11 and the DB updating step S12, The beacon 10 and the location of the tracked object can be tracked by receiving the location information transmitted together with the unique information.

As the above-described signal transmission step S21 to the positioning step S41 are continuously performed, the position information of the beacon 10 and the tracked object, which are registered and lost, are generated momentarily and cumulatively accumulated, The path can be grasped in real time.

The time series position information of the tracked object established through the position recording step S41 is provided to the owner or the investigation agency of the lost article so that it can be utilized for the recovery of the lost article. As shown in the lower part of FIG. 3, A position notification step S45 is performed in which the management server 40 fetches the stored position information and transmits the position information to the user terminal 21 that has performed the initial loss registration step S11, The position can be confirmed in real time as shown in the right side of FIG.

Meanwhile, as described above, it is possible to protect the privacy of the unspecified number of users by excluding the information that can identify the individual mobile terminal 20 in the information transmission step S23, but the mobile terminal 20 In order to protect user privacy information more securely, it is possible to perform after confirming to the user whether or not to transmit the location information. Such an example of conditional location transmission is shown in FIG.

The conditional location transmission embodiment of the present invention starts with the loss registration step S11 as described above with reference to FIG. 5, and the DB update step S12, the signal transmission step S21, and the signal reception step S22 are performed .

When the signal receiving step S22 is completed, the application installed in the mobile terminal 20 transmits the identification information of the mobile terminal 20 and the received unique information to the management server 40 through the wireless network 30 Unlike the information transmission step S23 described above, the location information of the corresponding mobile terminal 20 is not transmitted, and a telephone number or ID that can specify the mobile terminal 20 And the unique information transmitted from the beacon 10 are transmitted to the management server 40. [

Thereafter, a DB inquiry step S31 is performed in which the management server 40 inquires the database 45 with the received unique information. When the received unique information is set to the lost state, the management server 40 transmits the unique information to the mobile terminal 20, A position request step S32 for requesting the position information is performed successively.

The application of the mobile terminal 20 receiving the location request inquires whether the location information is transmitted or the like by outputting a screen for waiting a command of the user on the touch screen screen. When the user of the mobile terminal 20 performs a touch operation or the like to accept the transmission of the location information, the mobile terminal 20 transmits the location information to the management server 40, A position transmission step S35 is performed.

When the position transmission step S35 is completed, the management server 40 performs the position recording step S41 for recording the corresponding position information in the database 45, thereby enabling the above-mentioned lost object position tracking to be performed. Likewise, the position notification step (S45) in which the management server 40 transmits the location information to the user terminal 21 is added, so that the owner can grasp the location of the lost property in real time as shown in the right side of FIG.

Whether the article to which the beacon signal is transmitted is lost or forgotten in the performance of the lost property tracking step S11 to the location notification step S45 is determined by the mobile terminal 20, The management server 40 that has received the unique information from the server 45 inquires the database 45 to confirm whether or not it is loss-registered unique information.

Accordingly, the subject performing the determination as to whether or not to be lost is limited to the management server 40, and not only all the loss determination related processing is concentrated on the management server 40, but also the unique information transmitted from the unspecified number of mobile terminals 20 is collected Communication between the mobile terminal 20 and the management server 40 through the wireless network 30 is continuously repeated, which may result in excessive communication load operation and communication network incapability.

In the present invention, as shown in FIG. 6, the determination as to whether or not to be lost is distributed and processed to the mobile terminal 20, thereby efficiently operating the computer resources of the management server 40 and reducing communication load, Thereby minimizing the computational resources and power consumption of the mobile terminal 20.

This initiative embodiment of the mobile terminal 20 of the present invention starts with the loss registration step S11 as described above, as in Fig.

Thereafter, a DB update step S12 is performed in which the management server 40 receives the identification information, sets the unique information of the beacon 10 corresponding to the received identification information to a lost state, and updates the database 45, A server connection step S15 is performed in which an application installed in the mobile terminal 20 is connected to the management server 40 via the wireless network 30. [

In the server connection step S15, the application installed in the mobile terminal 20 is periodically connected to the management server 40. This is because the application and the management server 40 are connected to the management server 40, And the application is connected to the management server 40 irrespective of whether the management server 40 is actively calling or not.

Thereafter, a list transmission step (S16) of the management server (40) fetching the lost information registered in the database (45) and transferring the unique information to the mobile terminal (20) A list updating step S19 is performed in which the list information stored in the storage device of the mobile terminal 20 is updated with information so as to perform a function similar to the database 45 actually connected to the server in the storage device of the mobile terminal 20 A separate information recording system is established.

Regardless of whether the loss registration step (S11) to the list updating step (S19) are performed or not, a beacon (10) mounted on the tracked object periodically transmits a radio signal including unique information Is continuously performed and a signal receiving step S22 in which an unspecified number of mobile terminals 20 located around the beacon 10 receive the unique information transmitted by the beacon 10 is also continuously performed.

When the signal reception step S22 is completed, a list inquiry step S25 is performed in which the application mounted on the mobile terminal 20 inquires the list information with the received unique information. Then, the received unique information is transmitted to the list information An acquisition notification step (S26) in which the application installed in the mobile terminal 20 transmits the location information of the mobile terminal 20 and the received unique information to the management server 40 through the radio network 30 is performed do.

That is, instead of transmitting the unique information transmitted from the beacon 10 to the management server 40 unconditionally, as in the embodiments of FIGS. 3 and 5, It is checked whether the unique information received through the list inquiry step S25 is loss-registered unique information, and the unique information is transmitted to the management server 40 only when it is lost and registered unique information.

3 and FIG. 5, the communication load between the mobile terminal 20 and the management server 40 can be significantly reduced, and in a normal situation when a new loss registration does not occur, And thus, efficient operation can be achieved.

When the acquisition notification step S26 is completed, the management server 40 performs a positioning step S41 for storing location information in the database 45, and then the management server 40 transmits location information to the user terminal 21 (Step S45) is added, it is possible to implement the screen of the user terminal 21 as shown in the right side of FIG.

As described above, list information for performing functions similar to those of the database 45 connected to the management server 40 is constructed in the individual mobile terminals 20, and the determination of the loss is distributed to a plurality of mobile terminals, However, in order to implement real-time tracking of the lost tracked object, it is necessary to continuously update the list information and also to shorten the update period.

That is, if a loss event occurs and the loss registration step S11 and the DB update step S12 are performed, the list information of the mobile terminal 20 needs to be updated as soon as possible. To this end, S15), the connection period of the application management server 40 should be shortened as much as possible.

However, since the connection period of the management server 40 may be shortened, excessive communication load may be increased and computer resources may be invaded. Accordingly, in the present invention, the management server 40 is connected to the management server 40 through a communication network The push server 50 is operated in cooperation with the mobile terminal 20 so that the information necessary for updating the list information is transmitted to the mobile terminal 20 through the push service when a loss event occurs, ) Allows immediate updating of list information without connection.

A push server 50 is a server for providing a push service and is connected to a wireless network 30 such as a mobile communication network or a wireless LAN to transmit a relatively small amount of information to the mobile terminal 20. [

The push service based on the wireless network 30 is a conventional pull service method in which a device connected to a wireless network 30 such as a smart phone or a tablet PC accesses a specific server on the Internet as a client to request specific information, The push server 50 connected to the wireless network 30 regardless of whether the mobile terminal 20 is connected to the wireless network 30 or whether the mobile terminal 20 is connected to a specific server on the Internet Meaning that a relatively small amount of information such as a simple string type is transmitted unilaterally.

The push service based on the wireless network 30 is generally provided by the maker of the connected equipment operating system or the communication company of the wireless network 30. Typical examples thereof include an Apple Push Notification Service (APNS) provided by Apple, And GCM (Google Cloud Messaging), which is produced by Google.

Since the push service based on the wireless network 30 can be regarded as a kind of broadcast or multicast communication, it is possible to prevent a computer connected to the wireless network 30, that is, Consumption can be reduced.

The embodiment of applying the push server 50 of the present invention also starts with the loss registration step S11 as shown in FIG. 8, and then the DB update step S12 is performed.

When the DB update step S12 is completed, an information delivery step S17 is performed in which the management server 40 transmits the lost information registered in the push server 50, and then the push server 50 transmits the push- A push transmission step S18 for transmitting unique information to the mobile terminal 20 is performed.

When the push transmission step S18 is completed, a list updating step S19 is performed in which the application stored in the mobile terminal 20 updates the list information stored in the storage device of the mobile terminal 20 with the received unique information, In fact, a separate information storage system for performing functions similar to the database 45 connected to the server in the storage device of the mobile terminal 20 is constructed.

Regardless of whether the loss registration step (S11) to the list updating step (S19) are performed or not, a beacon (10) mounted on the tracked object periodically transmits a radio signal including unique information Is continuously performed and a signal receiving step S22 in which an unspecified number of mobile terminals 20 located around the beacon 10 receive the unique information transmitted by the beacon 10 is also continuously performed.

When the signal reception step S22 is completed, a list inquiry step S25 is performed in which the application mounted on the mobile terminal 20 inquires the list information with the received unique information. Then, the received unique information is transmitted to the list information An acquisition notification step (S26) in which the application installed in the mobile terminal 20 transmits the location information of the mobile terminal 20 and the received unique information to the management server 40 through the radio network 30 is performed do.

Thereafter, the position recording step S41 and the position notification step S45 as described above are performed so that the position of the tracked object can be grasped in real time.
