The location signal generator 10 may be divided into areas for each floor and room of a building, and may be installed for each of the separated areas, and the location signal generator 10 preferably generates at least one of a Wi-Fi signal and a Bluetooth signal.

The positioning terminal 20 maps the identification information for identifying the location information sender to the location signal generated by the location signal generator 10 to generate location information, and then directly transmits the location information to the network 30. do. The positioning terminal 20 may be a smart phone carried by the user who can receive the location signal, it may be a separate terminal capable of receiving the location signal.

A position signal processor 22 for processing the position signal received by the position signal receiver 21; A location information generator (27) for generating location information by mapping identification information for identifying a location information sender to a location signal processed by the location signal processor (22); And a location information transmitter 28 which directly transmits the location information generated by the location information generation unit 27 to the network 30 or propagates in the space.

In addition, the positioning terminal 20, as shown in Figure 4, the control unit 23 for controlling the overall operation of the positioning terminal 20, display the location information or evacuation route information when a disaster such as a fire, etc. The display device 24 may further include a display unit 24 for displaying the information, a storage unit 25 for storing the received position signal or evacuation route information, identification information, and the like, and an input unit 26 for the user to input an operation command.

Although not shown in FIG. 4, the positioning terminal 20 may further include an evacuation information receiver for receiving evacuation route information transmitted from the location integrated manager 40.

The network 30 plays a role of transmitting and receiving data between the location confirmation terminal 20 and the location integrated manager 40, and may be implemented as a Wi-Fi network, a 3G network, or the like. If necessary, it is also possible to transmit and receive data between the positioning terminal 20 and the integrated manager 40 using a local area network without using the network 30.

The location integrated manager 40 receives the location information through the network 30, classifies it by identification information, registers it in the location database 45, and based on the speaker line detection signal transmitted from the location signal generator 10. It displays an abnormal track as a function, and generates a situation coping information based on the location information registered in the location database 45 in case of an emergency and transmits it to the location confirmation terminal 20. In addition, the location integrated manager 40 also transmits a transmission message including a location signal to the location signal generator 10. In addition, the location integration manager 40 may receive location information transmitted through the location signal generator 10.

The location integrated manager 40, as shown in Figure 5, the location signal receiving unit for receiving the location information transmitted from the positioning terminal 20; A position signal classification unit 42 for classifying the identification information and the position signal from the position signal received by the position signal receiving unit 41; A position signal manager 44 for registering the identification information and the position signal classified by the position signal classifier 42 in the position database as anti-lost and disaster prevention information; A fire detector 47 detecting a fire; A control unit 43 for controlling the generation and transmission of evacuation route information when a fire is detected by the fire detection unit 47; An evacuation route information generator 46 for generating evacuation route information for each building location under the control of the controller 43; It includes an evacuation information transmission unit 48 for transmitting the evacuation path information generated by the evacuation path information generating unit 46 to the positioning terminal 20.

In addition, the location integrated manager 50 includes a line state receiver 71 for receiving the speaker line detection signal and the position information transmitted from the broadcast system 60; The apparatus further includes a line state indicator 72 for displaying the speaker line detection signal received by the line state receiver 71 on a screen so that an administrator can recognize the line signal.

Preferably, the location integrated manager 40 further includes a lost information indicator 49 for displaying lost information generated based on the location information stored in the location database 45. The lost information indicator 49 may display location tracking result information for each building, floor, and room under the control of the controller 43.

The broadcasting system 60 controls the emergency broadcast in association with the location integrated manager 40, transmits a location signal to the location signal generator 10, and obtains the speaker line obtained from the location signal generator 10. It serves to transmit the detection signal and the location information to the location integrated manager 40.

The amplifier 50 amplifies the emergency broadcast signal and the position signal output from the broadcasting system 60 and transmits it to the position signal generator 10, which is transmitted from the position signal generator 10 through PLC communication. It delivers a speaker line detection signal and location information to the broadcast system 60. In this case, when the broadcast signal is not generated in the broadcast system 60, the amplifier 50 amplifies only the position signal output from the broadcast system 60 and transmits it to the position signal generator 10.

The operation of the location tracking system using public address broadcasting according to the present invention configured as described above will be described in detail.

First, the location signal generator 10, which is an existing PA system, is installed in each room of each floor of the building, and the location signal generator 10 transmits a message transmitted from the location integrated manager 40. According to the position signal is generated. For example, the location integrated manager 40 continuously transmits a transmission message for generating a location signal to the location signal generator 10 installed in each room in real time or has a specific period.

The transmission message is output together with the broadcast signal through the broadcast system 60, and the amplifier 50 amplifies the position signal including the broadcast signal to position signal generator 10 provided in each room through the speaker line To send. Here, even when there is no broadcast signal, the position signal is transmitted to the position signal generator 10 through the amplifier 50 periodically or in real time.

The position signal generator 10 transmits a broadcast signal output through the amplifier 50 through the speaker 11.

At this time, the signal power converter 12a of the power supply unit 12 converts the broadcast signal received through the speaker line into power. Since the broadcast signal (voice signal) received by the speaker line is a power signal, it is possible to convert the voice signal into power. For example, in broadcasting or the like, the transmitting side converts the voice into a voice signal current by a microphone, a telephone transmitter, or the like, and the receiving side converts the transmitted current into a voice by a speaker or earphone. Therefore, the voice signal can be regarded as a power signal. In the absence of a broadcast signal, the power supply unit 12 converts the position signal into power.

The converted power signal is charged in the charging unit 12b. The charging unit 12b discharges the charged power to supply the signal generator 13. The signal generator 13 generates the position signal received by driving with the supplied power as one of the Wi-Fi signal and the Bluetooth signal. Here, the Wi-Fi signal or the Bluetooth signal is generated according to the configuration of the signal generator 13. By using the charging unit 12b as described above, it is possible to continuously and stably supply power for generating a position signal.

As such, the present invention does not provide a separate power supply line for generating a position signal, and by using a speaker line that is already installed for public address broadcasting as it is, power supply for signal generation while reducing wiring costs for power supply. It becomes possible.

On the other hand, the line abnormality detection unit 14 of the position signal generator 10 continuously detects the signal of the speaker line, and determines whether or not the line abnormality. For example, the line abnormality detection unit 14 detects the current of the speaker line, and when the current of the set value or more is detected, determines that the line is normal. Otherwise, the line abnormality detection unit 14 determines that the line abnormal has occurred. When it is determined that the line is abnormal, a line abnormality detection signal is generated and transmitted to the amplifier 50 through power line communication (PLC). In this case, the line abnormality detection signal may preferably include a line classification signal for distinguishing the speaker line where the line abnormality has occurred. Here, the line division signal is set in advance for each speaker line unique number. When the line abnormality detection signal is generated, the line abnormality detection unit 14 includes a speaker line unique number in the line abnormality detection signal.

The amplifier 50 transmits the line abnormality detection signal generated from the position signal generator 10 to the broadcasting system 60. The broadcast system 60 processes the transmitted line abnormality detection signal into a signal capable of recognizing it, and then extracts a speaker line unique number from the processed signal to recognize which speaker line has failed. After that, information on the speaker line where the failure occurs is displayed through a separate display device. As a result, the broadcasting equipment manager can easily know which speaker line has an error.

On the other hand, in a state in which each position signal is generated as described above in each room in the room, when the user having the positioning terminal 20 enters the corresponding room, the positioning terminal 20 automatically detects the position signal. Receive Here, the positioning terminal 20 may be referred to as a general smartphone or anti-lost terminal. The positioning terminal 20 is basically provided with a receiving device that can receive a Wi-Fi signal or Bluetooth signal. Depending on what position signal is used, the receiving device of the positioning terminal 20 may be implemented corresponding to the position signal.

As shown in FIG. 4, the positioning terminal 20 receives the position signal generated from the position signal generator 10 in the position signal receiver 21 and converts the position signal into an electrical signal. For example, the position signal receiver 21 includes a Fourier transformer or the like and converts a signal for a frequency domain into an electric signal of a predetermined size.

The position signal converted into an electrical signal is transmitted to the position signal processor 22. The position signal processor 22 converts the converted position signal into a digital signal, extracts the position identification signal from the converted digital signal, and transfers the position identification signal to the controller 23.

The control unit 23 stores the transmitted position identification signal in the storage unit 25. When the storage of the position signal is completed, the position information generation unit 27 under the control of the control unit 23 is the position identification signal stored in the storage unit 25 and the positioning terminal 20 previously registered in the storage unit 25. Location information is generated by mapping the identification information.

Therefore, the generated position information becomes a position signal (position identification signal) + identification information. The identification information is information for identifying which terminal is the terminal that transmitted the location information. In the case of a smartphone, the identification information includes a terminal phone number, a device unique number (ESN), and the like. In the case of a dedicated terminal, it may be a device unique number (ID). Here, since the device unique number (ID) and the information of the terminal holder are matched, the terminal holder information can be grasped with only the device unique number.

The location information generated by the location information generator 27 is transmitted to the location information transmitter 28, and is directly transmitted to the network 30 through the location information transmitter 28 without going through a separate relay device.

That is, the present invention is provided with a location signal generator in each location or each room of the building, and a user carrying a smart phone or a dedicated terminal enters the location or each room automatically, and automatically receives the location signal. It generates and transmits it to the remote location integrated manager 40 located.

In addition, in the above case, if the positioning terminal 20 is normally connected to the network 30, there is no problem, but if the positioning terminal 20 is unable to connect to the network 30, the position is It is impossible to transmit the location information to the integrated manager 40. Therefore, in the present invention, the location signal generator 10 relays the location information so that the location information can be continuously and stably transmitted to the location integrated manager 40 even when the network 30 cannot be connected as described above. For example, when the position information is generated from the positioning terminal 20, the line abnormality detecting unit 14 of the position signal generator 10 detects it. Here, the line abnormality detection unit 14 includes a communication module for short-range wireless communication or RF communication, and receives location information transmitted from the positioning terminal 20. The received position information is transmitted to the amplifier 50 through PLC communication. The location information transmitted in this way is transmitted to the location integration manager 40 via the broadcast system 60.

As shown in FIG. 5, the location integrated manager 40 receives a location signal transmitted from the location confirmation terminal 20 through the network 30 in the location signal receiver 41. In addition, the line state receiving unit 71 receives the line state detection signal and position information. In this case, when the position information is received from the position signal receiving unit 41, the position information received by the line state receiving unit 71 is ignored. Otherwise, if the position signal is not received from the position signal receiving unit 41, the line The position signal received by the status receiver 71 is used. The position signal receiver 41 converts the received position signal into an electrical signal and transmits the converted position signal to the position signal classifier 42.

The position signal classification unit 42 classifies the position information (position identification signal) and the identification information from the received position signal and transmits it to the control unit 43. The control unit 43 provides the location signal management unit 44 with the location information and the identification information or the location information received by the track state receiving unit 71 classified and transmitted. Accordingly, the location signal management unit 44 registers the provided location information and identification information in the location database 45. At this time, when registering the information in the location database 45, it is preferable to separately register whether to provide disaster information or prevention information based on the location information and identification information. For example, if the current location tracking target is lost based on the identification information, it is advantageous to store the information separately in the lost area in terms of later information utilization and management. In addition, if the current location tracking target is to provide an evacuation path in the event of a disaster or fire, it is advantageous to store it separately in the disaster protection area in terms of future information utilization and management.

Through this process, location tracking is performed for each location in the building, and location tracking information is registered in the location database 45.

On the other hand, the fire detector 47 continuously detects whether a fire occurs in the building, and when a fire is detected as a result of fire detection, the fire detector 47 transmits a fire detection signal to the controller 43. In this case, the fire detection signal preferably includes location information that can identify where the fire occurred. The location information is assigned a unique number for each fire detector, it is possible to easily recognize the location of the fire by mapping the location information to the unique number.

When the fire detection signal is transmitted, the control unit 43 transmits the location information of the fire occurrence to the evacuation path information generator 46 to generate the evacuation path information. The evacuation route information generating unit 46 generates the evacuation route information based on the location information when the location information of the fire is transmitted. Here, the evacuation route information is preferably generated in advance and stored in the internal memory in order to safely evacuate to each disaster occurrence location, such as a fire occurrence for the building.

Therefore, when the evacuation path information generation unit 46 is provided with the location information of the fire occurrence, retrieves the evacuation path information stored in the internal memory to generate the evacuation path information corresponding to the location of the fire and transmits it to the control unit 43.

When the evacuation route information is transmitted, the control unit 43 extracts the location tracking information stored in the building by tracking the location in association with the location signal management unit 44. Here, the location tracking information means terminal identification information and location information of the corresponding terminal.

Thereafter, the extracted tracking information is matched with the evacuation path generation information and transferred to the evacuation information transmission unit 48. For example, if the location of the fire is located in the first floor room No. 1, matching the information of the evacuation path to be sent to the target person located in the first floor room 1, and matches the evacuation path generation information to be transmitted to the target person located in the first floor room. In this way, evacuation information is matched with all tracked subjects in the building. Here, the evacuation path creation information may be different for each floor and room, or may differ only for each floor, and may be divided into groups by dividing the floor and the room into groups according to the structure of the building.

The evacuation information transmitter 48 transmits the evacuation path generation information mapped for each tracking subject to each subject individually as described above. In this case, it is preferable to directly transmit the generation information to the target through the network 30.

Those who are located in the building where the fire occurred will receive the evacuation information through the positioning terminal 20 carried by each of them, and by evacuating quickly through the evacuation information received in this way, to be safe from the fire occurrence It becomes possible. For example, in the present invention, when a person carrying a terminal capable of receiving a location signal enters a building, real-time location tracking is automatically performed. After that, when a fire occurs in the building, the evacuation route information corresponding to each location is received by the positioning terminal in real time. Therefore, the person carrying the positioning terminal does not shake, but sees the evacuation information displayed on the positioning terminal, it is necessary to evacuate quickly. As a result, valuable lives can be safely protected even in the event of a fire.

On the other hand, the present invention is also possible to track the position as described above, but also receives the line state of the speaker line provides the line state information so that the administrator can quickly respond to the speaker line has a problem.

For example, the line state receiver 71 receives the line state detection signal in association with the broadcast system 60. The received line state detection signal is transmitted to the controller 43. When the line state detection signal is transmitted through the line state receiving unit 71, the controller 43 stores the line state detection signal in the internal memory and transmits the line state detection signal to the line state indicator 72. The line state indicator 72 displays on the screen the line information in which an abnormality occurs according to the line state detection signal transmitted. This makes it easy for an administrator to know which speaker line has an error without directly checking the line condition of the speaker line.

After that, the manager takes action on the speaker line, thereby solving the problem of emergency broadcasting not being made due to a malfunctioning speaker line or inability to identify a user's location in the room.

In addition, as another feature of the present invention, the anti-lost function is possible based on the above location tracking information. For example, when the location tracking target is lost in the above manner, location tracking information is acquired in real time and stored in the location database 45. In this state, if the guardian lost the child, you do not have to go around the building to find the child one by one, only to provide the child information to the administrator who manages the integrated location manager (40). Here, it is assumed that the unique number of the mobile terminal for location identification carried by the child and the child information (name, age, parent telephone number, etc.) are mapped.

Although not illustrated in FIG. 5, the administrator inputs eye information through the input device and inputs the lost child function into the location integrated manager 40. When the lost child function is input, the control unit 43 executes the lost child program through the internal memory, and transmits the input eye information to the position signal manager 44.

The position signal manager 44 searches the position tracking information stored in the lost information area registered in the position database 45 using the eye information as an index, and extracts the position tracking information corresponding to the eye information. The extracted position tracking information is transmitted to the control unit 43.

The control unit 43 transmits the delivered location tracking information to the lost information display unit 49, and the lost information display unit 49 displays the received location tracking information on the screen. At this time, the location tracking information displayed on the screen displays the current location information of the lost child in the building. The location information of the displayed Mia is tracked and displayed in real time when the Mia moves in the building.

Therefore, the manager and the child guardian can accurately recognize the current position of the child in the building where GPS is not received, thereby preventing the occurrence of the missing child in the building.

In addition, as another feature of the present invention, it is possible to implement functions such as access restriction based on location tracking information tracked in real time. For example, the location tracking information of any person can be accurately identified through the location tracking method of the present invention. Therefore, it is possible to distinguish whether the tracer is a person who can freely enter or leave the building, the floor, or the room. Based on the separated information, it is possible to restrict the access of the target person.

The present invention is not limited to the fields mentioned in the embodiments as described above, it will be apparent that it can be applied to all fields that can perform the location tracking information, the location tracking information.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
