More specifically, FIG. 2 shows a matter-of-the-art Internet system having an automatic group setting function implemented in a place where medical service is provided.

2, R (R1 to R6) is a service terminal R, M (M1 to M3) are a plurality of user terminals M, and SRs (SR1 to SR14) (SR), and S (S1 to S6) show service types.

As shown in FIG. 2, the relay station SR is fixedly installed at a specific position in the service space. At this time, the relay terminals (SR) are mutually connected by wire. The relay station SR performs radio communication with a service terminal R or a user terminal M existing in a region that it is in charge of, in more detail, an area in which it can communicate with the relay terminal SR.

 In addition, the plurality of service terminals R and the user terminals M may be fixedly installed in a specific service space, or may be mobile terminals. 2 shows the wheelchair R1 and the household appliance R2, the printer R3, the electrocardiogram meter R4, the blood pressure meter R5, and the temperature meter R6 as the service terminal R. The mobile terminal M1, the tablet PC M2 and the desktop M3 are shown as the user terminal M. [ In this case, although not shown, each service terminal R may be provided with a communication module for communicating with the relay terminal SR.

2 shows a first service S1 for receiving the movement information of the wheelchair R1 at the relay terminal SR8 and providing the movement information to the user terminal M2 and the service request information provided from the user terminal M2 to the relay terminal SR8, The second service S2 that is provided to the home appliance R2 via the first and second home appliances SR8 and SR4 and provides the driving service and the service request information provided from the desktop M3 are transmitted to the printer R3 via the relay terminal SR10, And the service request information provided from the user terminal M2 is provided to the electrocardiogram meter R4 through the relay terminals SR12 and SR3 to provide the electrocardiogram measurement service A fourth service S4 and a fifth service S5 that provides the service request information provided from the user terminal M2 to the blood pressure monitor R5 through the relay terminals SR13, SR8, and SR3 to provide a blood pressure measurement service, And the service request information provided from the user terminal M2 is transmitted to the relay terminals SR14, SR8, SR3 A sixth service S6 is provided to the temperature gauge R6 to provide a temperature measurement service. Here, the fourth to sixth services S4, S5, and S6 are configured to provide the result information measured by the service terminals R4, R5, and R6 to the corresponding user terminal M through the relay terminal SR can do.

On the other hand, FIG. 3 is a block diagram showing the internal structure of the relay terminal SR shown in FIG. 1 functionally separated. The relay terminal SR9 of the "X" service area shown in FIG. 2 will be described. 3 shows a configuration in which the relay terminal SR9 is wire-coupled.

3, the relay terminal SR9 includes a radio processing unit 10 for performing radio communication with the service terminal R3 or the user terminal M3, a data memory 20, and a control unit 30 for overall control of the apparatus.

The radio processing unit 10 may be configured to perform various types of wireless communication with the service terminal R3 or the user terminal M3 using WiFi or Bluetooth. At this time, the radio processing unit 10 receives a beacon signal from the user terminal M using the LIDx (Location ID Exchange) protocol, thereby collecting real-time location information about the user terminal M. [

The data memory 20 stores status and access information for the service terminal R3 or the user terminal M3 and the grouped other terminals SR10 and SR6 located in the jurisdiction area of the relay terminal SR9, And stores the group setting information for the service including the relay terminal SR9. The group setting information includes status information on the currently set service terminal R3, the user terminal M3 and the relay terminals SR9, SR10 and SR6, and the information provided from the controller 30 The service group information including the status information of the terminal is updated in real time. In addition, the data memory 20 includes a look-up table including information on service terminals (R) for each relay station (SR).

The control unit 30 receives the status information of the service terminal R3 or the user terminal M3 located in the jurisdiction area provided from the radio processing unit 10 in real time and receives the status information from the service terminal R3 or the user And performs state management for the terminal M3. The control unit 30 manages information on the service group to which the service group belongs and communicates with another service terminal according to the state of the service terminal R3 and the user terminal M3 belonging to the service group, And is configured to change the area.

That is, the control unit 30 sets a service group corresponding to the service based on the service request information of the user terminal M3 located in the corresponding jurisdiction area. At this time, the control unit 30 searches the service terminal R3 corresponding to the service request from the user terminal M3 through the lookup table registered in the data memory 20, and communicates with the retrieved service terminal R3 And sets the service group so that the relay terminal SR10 that controls the service terminal R3 is included. At this time, the service group includes at least two relay terminals SR9 and SR10, and includes a relay terminal SR9 managing the user terminal M3 requesting the service and another relay terminal SR10 neighboring the relay terminal SR10 Set up a service group. This is because, even if an error occurs in any one relay terminal (SR) forming a service group, the service is continuously maintained by sharing group information through another relay terminal (SR) of the corresponding service group.

In setting the service group, the controller 30 checks whether there is a service terminal R3 'performing the same function as the service terminal R3. If the service terminal R3' exists, It is preferable to set the service group so that the relay terminal SR6 that manages the terminal R3 'is included. This is because the service terminals R3 and R3 'providing the same service are set as one service group so that even if any one service terminal R3 fails, the service is continuously provided through the other service terminal R3' .

In addition, the controller 30 is configured to manage the state of another relay terminal SR10 through wire communication with a neighboring other relay terminal SR10. At this time, although not shown, the relay terminal SR9 may be configured to include a communication port and a communication module for performing wire connection with the other relay terminal SR10.

The relay terminal SR9 may include information input / output means including an input unit for an administrator to input various information and a display unit for displaying status information, although not shown.

FIG. 4 is a diagram illustrating an automatic group change setting state processed by the control unit 30 shown in FIG.

4, the process of setting the area of the first service group (SG1-> SG11) for the first service (S1) and the process of setting the area of the second service group (SG2-> SG22) Respectively.

That is, in FIG. 4, when the first service group SG1 terminates the service execution for the user terminal M requesting the service or if the service terminal R set as the corresponding group has failed, M) or the service terminal R is excluded from the first service group SG1 so that the first service group SG1 is automatically reduced (SG11). At this time, A plurality of relay stations SR set in the first service group SG1 determine the current state according to the location of the user terminal M through mutual communication and also determine the current state based on the state information provided from the service terminal R If the service execution is terminated or all the user terminals M set as the service group are moved to another location, the corresponding service group is disassembled C. At this time, the information relating to the dissolution service groups are all removed. This is done to so that, with Sikkim further improve the use efficiency of the data memory 30 and improve the processing speed in accordance with the group setting.

In addition, in FIG. 4, when the arbitrary user terminal M requesting the corresponding service performs the service request to the relay terminal SR in a position not belonging to the group area, the second service group SG2 transmits the service request to the corresponding relay terminal SR (SG2) is automatically extended and set so that the second service group SG2 is additionally included.

Next, the operation of the object Internet system having the automatic group setting function shown in FIG. 1 will be described with reference to FIG. Hereinafter, the service operation for the "X" area in the system shown in FIG. 2 will be described by way of example.

First, at least two mutually adjacent relay terminals (SR) are set as a basic group. At this time, at least two relay terminals (SR) set as a basic group can be configured to control the same service area. It goes without saying that the relay terminal SR can be independently configured without setting a basic group.

In addition, a lookup table including relay service terminal service terminal information is registered in the relay terminal SR. At this time, the service terminal R may have mobility according to the type of the terminal. In consideration of this, the service terminal R is configured to update the service terminal information corresponding to the relay terminal in the lookup table through real- .

In the above state, each relay terminal SR receives and stores state information on the service terminal R located in its service area in real time (ST1). At this time, if the current state of the service terminal R is changed, the service terminal R wirelessly transmits the state information to a relay station (SR) that manages the service for the current location area.

Also, the user terminal M wirelessly transmits the LIDx beacon signal at regular intervals, and the relay station SR that manages the area where the user terminal M is located receives the beacon signal provided from the user terminal M The user terminal M is registered.

At this time, when a service request is made from the arbitrary user terminal M3 to the first relay terminal SR9 (ST2), the first relay terminal SR9 transmits the service request to the first service terminal The first service group is set to include the second relay terminal SR10 that manages the first service terminal R2 by searching the third service terminal R3. That is, the service area is set in the first service group so that the user can receive the output service through the user terminal M3 to the first printer R3. At this time, the first relay terminal SR9 searches for a second service terminal R3 'that provides the same service as the first service terminal R3, and the third relay terminal SR3, which is responsible for the second service terminal R6, The service area ("X" in FIG. 2) of the first service group can be set so that the terminal SR6 is included. If all of the terminals set as the first service group are in a normal state, the user terminal M3 transmits the first service terminal group to the first service terminal, which is the closest to the user terminal M3, through the first and second relay terminals SR9 and SR10, The first service terminal R3 is provided with the output service through the first printer R3 by providing the service request information to the first service terminal R3.

The relay terminals SR9, SR10 and SR6 set as the first service group mutually communicate with each other for the service terminal R3, the user terminal M3 and the relay terminals SR9, SR10 and SR6 set as the first service group By sharing the state information, the state of each terminal is monitored (ST4). At this time, the first to third relay terminals SR9, SR10 and SR6 monitor the states of the user terminal M3 or the first and second service terminals R3 and R3 'that communicate with the relay terminal . That is, the first relay terminal SR9 monitors the state of the user terminal M3, the second relay terminal SR10 monitors the state of the first service terminal R3, and the third relay terminal SR6 And monitors the status of the second service terminal R3 '.

In addition, when there is a state change such as a failure in any terminal forming the first service group, the first relay terminal SR9 changes or sets the currently set service path in the service group so as to correspond to the change of the state Or changes the area of the first service group to expand or contract as shown in FIG. 4 (ST5).

Hereinafter, the service path change or the area change setting method of the first service group according to the state change of the terminal set in the first service group will be described.

Here, if the access information for the user terminal M3 is not received from the second relay terminal SR10 or the third relay terminal SR6 for a predetermined time, the first relay terminal SR9 transmits Disassembly processing is performed. That is, the first relay terminal SR9 provides the first service group disassembly information to the second and third relay terminals SR10 and SR6, which are currently set as the first service group, so that the first to third relay terminals SR9, SR10, and SR6) of the first service group.

On the other hand, when the access information for the corresponding user terminal M3 is received from the second relay terminal SR10 or the third relay terminal SR6 within a predetermined time, the first relay terminal SR9 maintains the first service group And performs the requested output service from the user terminal M3.

2, when a failure occurs in the first service terminal R3

When there is a service request from a second user terminal to receive a service through a service terminal set as a service group, the relay terminal expands the area of the service group so as to include a fifth relay terminal that is in charge of the second user terminal And setting the automatic group setting function. A method for automatic group setting of an object Internet system comprising a plurality of service terminals, a plurality of user terminals, and a plurality of relay terminals requesting to provide a service requested from the user terminal through a service terminal,
Wherein each of the service terminals provides status information to the relay terminal managing the corresponding service terminal in real time and each relay terminal updates and stores the service terminal information connected to the relay terminal through communication with the other relay terminal ,
A second step of providing the status information of the user terminal to the first relay terminal that manages the user terminal and performing a service request,
A third step of searching for service terminal information corresponding to a service requested from the user terminal based on a lookup table including information on the service terminal of each relay terminal in the first relay terminal,
A fourth step of automatically setting a service group so as to include a first relay terminal in the first relay terminal and a relay terminal jurisdiction over at least two or more service terminals detected in the third step,
Monitoring the status information of the relay terminal, the service terminal and the user terminal constituting the service group set in the fourth step, and automatically changing the service path in the service group so that the service terminal in a state in which the service requested by the user terminal is connected, If the failure occurs in the first service terminal in the service group, changing the service path so that the service is provided through the second service terminal in the service group Wherein the automatic group setting method comprises the steps of: 15. The method of claim 14,
Wherein the first relay terminal determines the state of the user terminal based on the beacon signal periodically provided from the user terminal in the second step. 15. The method of claim 14,
In the fourth step, the first relay terminal sets a service group to include at least two relay terminals, and includes a first relay terminal managing the user terminal and a relay terminal neighboring the first relay terminal, Wherein the group setting unit sets the group to be automatically set. 15. The method of claim 14,
In the fifth step, the first relay terminal determines whether there is a failure between the relay terminal set as a service group, the service terminal and the user terminal, and whether there is another service terminal providing the same service as the first service terminal detected in the third step And changing the service path or the service area of the service group based on the status information including the information. delete 15. The method of claim 14,
In the fifth step, if the beacon signal is not received from the user terminal requesting the service in the service group for a predetermined time, the first relay terminal communicates with the other relay terminal set as the corresponding service group and clears the information about the service group And disassembling the corresponding service group. The automatic group setting method of claim 1, delete delete 15. The method of claim 14,
In the fifth step, if it is determined that a failure occurs in the first service terminal performing the service in the service group or the second relay terminal managing the first service terminal in the service group, the first relay terminal checks the lookup table, Searches for a third service terminal that performs the same service, and if the third service terminal exists, extends the service group to include the fourth relay terminal that is in charge of the third service terminal. Automatic group setting method in the object Internet system. 15. The method of claim 14,
In the fifth step, when there is a service request from the second user terminal to receive the service through the first service terminal set as the service group, the first relay terminal transmits the service request to the fourth relay terminal And setting an area of the service group so as to include the service group.
