Description

FIELD OF THE INVENTION The present invention relates to a system and method for storing information on persons,

In the present invention, a router provided in a certain space region performs periodic short-range wireless communication, which is typically performed without performing a separate authentication procedure from a user terminal located in a corresponding space region, to acquire snapshot information about the user terminal And generates and stores log information for a user terminal for judging life information based on the information, thereby enabling to obtain accurate name information of the corresponding region by using log information in the event of a disaster, Storage system and method thereof.

Personal Area Network (PAN) means having a unique network for each individual.

The above-mentioned PAN is a network in which a device owned by one person forms a network for the convenience of the person, and can be a network using the M2M communication function between devices for the convenience of a person, Expanding the connection of M2M can be an IoT system.

In the IoT environment, there are communicable devices that make up the IoT system, and users who are closely connected to it, that is, many people who are using or manipulating it. Here, although there are remote users operating the communication devices, most of them are devices carried by the user, and the movement of the devices can be grasped as the movement of the user who uses them. In the case of smart phones, bluetooth headsets, notebooks, wearable devices, etc., the mobility of the personal devices constituting the PAN, especially the wireless personal network, represents the mobility of the user.

In recent years, various types of location-based services capable of identifying and providing a user's location through the location of communication devices have been activated.

Despite the development of such communication technologies, however, many catastrophic accidents have never ceased. Various technologies have been developed such as location confirmation and guidance through GPS, traffic control through communication between vehicles, and verification. However, all of these technologies are capable of providing services only in areas where communication is possible. It is a reality that the above-mentioned service can not be provided in an isolated area.

In other words, in order to overcome the disaster caused by the accident in the real world, only basic information about how many persons exist in the disaster area, for example, under the sinking ship or under the buried building, is needed.

However, in the communication disconnection area, even if the communication technology can develop and provide various services, it is a reality that the basic information can not be secured and the rescue operation is difficult.

In addition, even if various types of user terminals are popularized and the number of user terminals is confirmed on the basis of whether or not the user terminal located in the disaster area is disconnected in the current state, the user terminal is simply identified with the user terminal, It is difficult to grasp. For example, there may arise a problem that two users are grasped with respect to two user terminals of a remote controller and a remote device performing M2M pairing communication.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a system configuration of a disaster-proof name information storage system using short-range wireless communication according to a first embodiment of the present invention.

1, a system for storing disaster-hit name information using a short-range wireless communication according to a first embodiment of the present invention includes a router 100, (200).

Here, each router 100 located in a different jurisdiction area is configured in combination with an external storage device 300 for storing log information including the location and time of the user terminal 200 located in the corresponding area. At this time, the router 100 and the external storage device 300 perform wired or wireless communication. Also, although not shown, the routers 100 in different jurisdictional areas can be configured to perform mutual communication.

In addition, the router 100 generates log information including a location and a time based on snapshot information provided from the user terminal through short-range wireless communication performed periodically with the user terminal located in the jurisdiction area, And the log information is configured to be backed up to the external storage device 300 when the predetermined condition is satisfied. At this time, the router 100 calculates the position of the pairing device based on the communication type of the pairing information and the signal strength from the snapshot information provided from the user terminal 200, and transmits the pairing device ID, And to generate log information that includes the pairing device location. That is, the router 100 may be configured to count and store the number of persons located in the jurisdiction area based on the pairing information included in the log information. At this time, the router 100 may be configured to count the number of persons and provide the generated personal information to the external storage device 300 together with the log information.

Also, the router 100 may be configured to be coupled with an external time server to receive current time information. This is to provide time information more accurately and stably, and can be applied to the router 100, which is preferably arranged in a situation where it is difficult to receive time information such as underground. It should be noted that the router 100 may include a timer (not shown).

1, the user terminal 200 is a device of various types that can be directly or remotely manipulated by a user, and includes snapshot information including status information of the terminal, a router 100 To the router 100 through the periodic communication performed to confirm whether or not the connection is established. That is, the user terminal 200 basically responds to the search request of the router 100, for example, the LIDx request, so that the corresponding device is registered in the router 100 to establish a connection state. Then, the user terminal 200 performs a communication process for confirming the connection status, which provides its status response information to the router 100 in response to the status request of the router 100 at a predetermined period. At this time, the user terminal 200 provides the router 100 with snapshot information including status information as its status response information. The status information items included in the snapshot information include an operation status, an input type, a storage time, a remaining energy, a device ID paired, And the user terminal 200 provides the router 100 with snapshot information including items that can be provided according to the type of the device. For example, if the user terminal 200 is a smart phone, it can provide all the snapshot items described above, and if the user terminal 200 is a Bluetooth headphone, it can provide no time item.

If the user terminal 200 is a device that supports only M2M-oriented connection, such as a Bluetooth mobile phone, a remote control, or a short-range wireless operation object (RC car), rather than a connection with the router 100, And information about the device connected to the device. At this time, it is determined whether the user is at the position of the user terminal 200 or the position of the pairing device based on the input type item of whether the user terminal is directly inputting or remote inputting in the snapshot information . In addition, when the pairing device ID is the same in the pairing information, it can be determined that one user uses a plurality of user terminals 200.

1, the external storage device 300 counts the number of people located in the jurisdiction area of the router 100 based on the log information provided from the router 100, and stores log information including the same device ID information The number of the user terminals is counted as one person. In addition, when the input type of the terminal is a remote input and the position of the pairing device is out of the jurisdiction area, And store it.

FIG. 2 is a block diagram showing the internal structure of the router 100 shown in FIG. 1 functionally separated.

2, the router 100 includes a terminal communication interface 110, a communication connection unit 120, a memory 130, and an information processing unit 140. As shown in FIG.

The terminal communication interface 110 is for performing communication with the user terminal 200 located in the jurisdiction area R and may be composed of various kinds of short range wireless communication interfaces. For example, the terminal communication interface 110 may include Bluetooth, ZigBee, NFC, and WiFi communication modules. That is, the terminal communication interface 110 receives the snapshot information from the user terminal 200 during the periodic connection confirmation with the user terminal 200.

The communication connection unit 120 is for communicating with the external storage unit 300 and may be composed of a wired or wireless communication module depending on the characteristics of the router 100 or the installation environment.

The memory 130 stores log information composed of various status information including the location and time of the user terminal 200 located in the jurisdiction area R provided by the information processing unit 140. [ At this time, a storage area for the registered user terminal 200 is set in the memory 130, and log information is stored in the corresponding storage area. 4, the log information stored in the memory 130 includes a router table RT, a plurality of user terminal tables DT registered in a jurisdiction area, For the terminal table DT, predetermined K pieces of log information (K records, DL) are stored.

The information processing unit 140 searches the user terminal 200 located in the jurisdiction area through the terminal communication interface 110 and registers the discovered user terminal 200 to register the user terminal 200 in a predetermined period, And stores the generated log information in the memory 130 based on the received snapshot information. The information processing unit 140 is configured to back up the log information stored in the memory 130 to the external storage device 300 when the predetermined backup storage condition is satisfied.

3 is a functional block diagram of the information processing unit 140. As shown in the figure, the information processing unit 140 includes a communication processing module 141, a log information generation module 142, a storage processing module 143, (144).

The communication processing module 141 performs data transmission / reception processing with the user terminal 200 and the external storage device 300 located in the jurisdiction area. That is, the communication processing module 141 performs data transmission / reception processing with the user terminal 200 through the terminal communication interface 110 based on a preset communication cycle, Transmits the log information to the external storage device (300) through the communication connection (120) and receives the backup response information provided from the external storage device (300).

The log information generation module 142 generates log information in the form of a record configured with predetermined items based on status information provided from the communication processing module 141, that is, snapshot information. As shown in FIG. 4, the log information DL of the record format includes a location of the corresponding user terminal, an operation status, an input type, a storage time, A backup time, a device ID paired, a communication type with a paying device, and a pairing location item. Here, the location and the pairing location are calculated by the router 100 based on the signal strength of the snapshot information. At this time, the method of calculating the position information according to the signal strength is a well-known technique, and a detailed description thereof will be omitted. The status indicates a current operation state of the user terminal 200. The input type indicates whether the device is a device receiving a direct input by a user or a device receiving a remote input, (Time) indicates a corresponding snapshot reception time, and the remaining energy (Remaining Energy) and the backup time (Backup Time) are referenced and stored in the user terminal ID table. The device ID paired, the communication type, and the paired location are pairing information for M2M communication with the corresponding user terminal 200, and are respectively associated with the corresponding user terminal 200 The device ID for communication, the pairing communication type, and the location information of the pairing device. For example, when the user terminal 200 is a headphone, the pairing device may be an audio device operated by a user, and the headphone and sounder period may perform Bluetooth communication. Also, when the router 100 can not confirm the information on the record item, the item is set to "null ".

The storage module 143 stores registration information for a user terminal located in a jurisdiction area in a memory and stores log information for the registered user terminal in a memory, The log information is stored in the area. 4, the storage processing module 143 generates a user terminal table (TD) based on the registration information of the user terminal 200 provided through the search process with the user terminal 200, And stores it in the storage area. In this case, the user terminal table (TD) includes a device class for distinguishing whether the user terminal is a mobile device or a fixed device, a communication type for classifying the type of the short-range wireless communication, A record location where the snapshot information for the user terminal is stored, a backup time of the log information for the user terminal, a snapshot information of the user terminal, a resister time, (In / Out) information for distinguishing whether the user terminal is located within a jurisdiction area or a location outside the jurisdiction area. The In / Out information is set to In information when the router 100 is located in an area covered by the router 100. When the in / out information is moved to an area managed by another router 100, Respectively. At this time, out information is set when movement information for the corresponding user terminal 200 is received from the other router. That is, in order to prevent the same person from being counted in the different jurisdictions when the number of persons is counted based on the user terminal 200 moving in a plurality of jurisdictions to be. For example, when the user terminal 200 registered in the area A moves to the area B after a lapse of a predetermined time, Out information is set for the user terminal in the area A and the number of persons is not counted. In information is set for the user terminal and the number of people is counted, thereby making it possible to prevent the error in the name information due to the counting of the number of persons corresponding to the user terminal in both the areas A and B to be controlled.

In addition, the storage module 143 counts the number of persons located in the jurisdiction area based on the log information, counts a plurality of terminals having log information including the same device ID information as one person, When the input type of the terminal is the remote input and the position of the pairing device deviates from the jurisdiction area, it is configured to generate and store the name information that does not count the number of persons for the user terminal.

The storage module 143 backs up the log information stored in the memory 130 to the external storage unit 300 when the predetermined backup storage condition is satisfied. For example, when the number of records for the corresponding user terminal 200 is a predetermined number (K), the storage processing module 143 backs up the log information stored in the user terminal 200 to the external storage 300 . At this time, the storage module 143 clears the log information stored in the external storage 300 in the memory 130, and updates the backup time of the corresponding user terminal table DT to the current backup time. The storage module 143 compares the state information including the location information generated by the log information generation module 142 with the previous log information. If it is determined that there is no state change, the storage module 143 stores only time information Update to the current time.

The period setting module 144 checks the battery remaining amount information from the snapshot information provided from the user terminal 200. If the battery remaining amount is less than a predetermined amount, the cycle setting module 144 sets the communication period with the user terminal 200 Change the setting so that it is longer. When the snapshot having no status change is continuously received from the user terminal 200 for a predetermined number of consecutive times or more, the period setting module 144 sets the communication period with the user terminal 200 to be longer than the currently set communication period Change the setting as necessary. This is to minimize the battery burden by optimizing to an unnecessary communication cycle in order to provide the service considering that the user terminal is a device operated by a battery.

Next, the operation of the personal information storage system in the communication disconnection area using the short-range wireless communication having the above-described configuration will be described with reference to the flowchart shown in FIG.

First, a router 100 is installed in a predetermined spatial area R and is coupled to be able to communicate with the external storage device 300.

The router 100 wirelessly transmits the search information in a broadcasting method to the user terminal 200 that has entered the area related to itself by a predetermined period (ST10). At this time, the router 100 wirelessly transmits search information corresponding to various communication protocols through the terminal communication interface 110.

 When the arbitrary user terminal 200 enters the corresponding space area and receives the search information transmitted from the router 100, the search response information is wirelessly transmitted to the corresponding router 100 (ST20) . At this time, the user terminal 200 wirelessly transmits the search response information including the device ID, device classification, and communication type information. The search response information may further include search response time information and battery remaining amount information.

The router 100 performs a registration process for the user terminal 200 that has entered the jurisdiction area based on the receipt of the search response information for the search information (ST30). At this time, the inter-router 100 generates the user terminal table DT shown in FIG. 4 based on the search response information and stores it in the memory 130. The router 100 determines and stores the storage location and the in / out items in the user terminal table DT.

Thereafter, the router 100 and the user terminal 200 in the search and registered jurisdiction region periodically communicate with each other to confirm whether or not they are connected. This is a periodic communication that is generally performed in wireless communication. In the present invention, communication is not additionally performed in response to request and response of additional status information for acquisition of lifetime information, The snapshot information is added and transmitted so that the burden of battery consumption due to communication for requesting and responding to the snapshot information can be minimized.

That is, the router 100 wirelessly transmits state request information to the user terminal 200 within a predetermined period (ST40). In response, the user terminal 200 in the jurisdiction area wirelessly transmits its own status response information to the router 100 (ST50). At this time, the status response information includes snapshot information for the corresponding user terminal 200.

Also, the router 100 can perform mutual communication at different periods according to the characteristics of the user terminals 200 in the jurisdiction area. For example, when the device classification of the user terminal 200 is "fixed ", that is, when the fixed device is a fixed device, the router 100 sets the communication cycle longer than the general communication cycle, or once the location and status information are registered It can be implemented so as not to carry out continuous communication. That is, the router 100 performs periodic communication including snapshot information for the user terminal 200, which frequently changes its position or changes its remaining battery level. In this case, the remaining battery capacity of the mobile terminal 200, which has mobility, is mostly operated by a battery. For a mobile device that is continuously located and can not be located at any moment, Is turned off or is automatically turned off due to a power exhaustion of the battery.

In step ST60, the router 100 generates log information in the form of a record shown in FIG. 4 based on the status response information received from the user terminal 200 in step ST50, and stores the log information in the memory 130 in step ST60. At this time, the router 100 basically calculates the location of the corresponding user terminal 200 based on the state response information, that is, the signal strength of the snapshot information, and extracts the storage time to generate log information. Also, the router 100 generates log information to include the pairing information of the snapshot information. Also, if there is no change in the location, the router 100 updates only the time information in the previous log information.

When the number of log information of the corresponding user terminal 200 stored in the memory 130 is equal to the preset number of backup log information, the router 100 stores the stored log for the user terminal 200 stored in the memory 130 Information to the external storage device 300 (ST70).

At this time, the external storage device 300 backs up the log information provided from the router 100, and provides backup response information including a backup time for receiving log information to the corresponding router 100 (ST80 ).

The router 100 clears the log information for the corresponding user terminal 200 in the memory 130 based on the reception of the backup response information provided from the external storage device 300, DT to the backup time received from the external storage 300 (ST90).

Meanwhile, when the backup response information is not received from the external storage device 300 and the memory area allocated to the user terminal 200 is saturated, the router 100 transmits the backup response information to the corresponding user terminal 200 The oldest log information in the memory area is cleared and stored. That is, the router 100 stores log information for a certain period or a certain period of time from the latest.

FIG. 6 is a diagram for explaining the operation of the snapshot creation and storage step (ST60) shown in FIG. 5 in more detail.

In step ST50, when the status response information is applied from the user terminal 200 to the router 100, the router 100 calculates the position in the jurisdiction area based on the signal strength of the status response information (ST61). Here, various known and known techniques can be applied to the method of calculating the position of the device based on the signal strength.

Then, the router 100 extracts time information corresponding to reception of the corresponding status response information (ST62). At this time, the router 100 extracts time information from the status response information, or extracts external or internal time information when the time response information does not include the time information.

In step ST63, the router 100 compares the location information calculated in step ST61 with the location information of the previous log information stored in the memory 130 to determine whether the location information has changed.

If it is determined in ST63 that no positional change has occurred in the comparison result between the current location information and the previous location information, the router 100 stores only the time information in the previous log information stored in the memory 130, (ST64).

On the other hand, if it is determined in step ST63 that a positional change has occurred as a result of comparison between the current location information and the previous location information, the router 100 extracts information corresponding to the preset record item from the status response information received in step ST50 And generates log information in the form of a record shown in FIG. 4 based on the extracted state information, the position information calculated in step ST61, and the time information extracted in step ST62 (ST65). At this time, the log information is configured to include the pairing information, which is generated by simply tracking the position of the user terminal, and thereby it is possible to grasp the number-of-persons information in the accurate space area.

That is, as shown in FIG. 7A, the total number of registered user terminals 200 located in the jurisdictional area R of the arbitrary router 100 is five (N1, N2, N3, N4, N5) Where N4 and N5 are remote control devices and the user is adjacent to the controller Z when communicating with the controller Z located outside the corresponding jurisdiction area, It is judged that the total number of persons existing in the corresponding jurisdiction area is 5 persons. However, since the two users are actually located at the position of the regulator Z, the total number of persons in the corresponding jurisdiction area must be three. In consideration of this situation, the router 100 determines that the input type of the user terminal is a remote input And if the position of the pairing device deviates from the jurisdiction area, it is configured to generate and store the name information, i.e. "3 ", which does not count the number of persons for the user terminal.

As shown in FIG. 7B, the total number of registered user terminals 200 located in the jurisdiction area R of the arbitrary router 100 is five (N1, N2, N3, N4, and N5) If N1 and N2 are controlled by N3, the number of user terminals 200 is five, but the number of users using N1, N2, and N3 is one. At this time, the terminal ID of the N3 log information and the pairing device ID of the N1 and N2 log information are set to be the same, and the router 100 considers the log information including the same device ID information It is possible to generate the name information, i.e., "3 persons " generated by counting as a person.

Also, although not shown, the router 100 is configured to store a user terminal registration table including in / out information according to whether or not the registered user terminal 200 is located in a jurisdiction area, And setting out information in the user terminal registration table when movement information for the user terminal 200 is received from another router in the area. In counting the number of persons located in the jurisdiction area based on the log information, And generates the name information that does not count the number of persons for the user terminal 200 in which the out information is set in the registration table.

Also, the router 100 additionally stores the log information generated in step ST65 in a corresponding user terminal storage area of the memory 130 (ST66). At this time, it is also possible to store the name information in the corresponding user terminal storage area.

That is, according to the embodiment, a router is installed in a communication disconnection area or an area where a communication disconnection is expected, and the location of the user and the location of the user using the information received through the periodic communication with the user terminal, And provides the log information to the external storage device.

Therefore, when an accident such as a disaster occurs in the area, it is possible to check the number of people located in the corresponding area based on the log information stored in the memory of the router or the corresponding log information backed up to the external storage device, .

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the scope of the appended claims should include all such modifications and changes as fall within the scope of the present invention.
