In addition, in the present embodiment, the position information includes the distance between two communication terminals 2 adjacent to each other (that is, the communication distance). The communication distance is calculated, for example, by the processing unit 12 based on the position information of the communication terminal 2 . The memory unit 13 may be a built-in memory of the processing unit 12 .

(2.2) Communication terminal Next, the communication terminal 2 will be described. In this embodiment, the communication terminal 2 is a fixed type communication terminal. That is, unlike a mobile communication terminal owned by a user such as a smartphone, the communication terminal 2 does not move from the installed place unless a situation such as changing the installation place occurs. In the present embodiment, a plurality of communication terminals 2 are electrically connected to one power line 3 . Here, if the power distribution system is a single-phase three-wire system, one set of power lines consisting of three lines (three wires) of L1, L2, and N is set as one power line 3 . Similarly, if the power distribution method is single-phase two-wire type, one group of power lines consisting of two wires (two wires) is set as one power line 3, and if the power distribution method is three-phase four-wire type, four wires (4 wires) 1 set of power lines constituted by a single power line 3. The plurality of communication terminals 2 use the power line 3 as a transmission path for communication signals, and perform power line communication (PLC: Power Line Communication) with each other. That is, in the present embodiment, the communication terminal 2 has a function of communicating with other communication terminals 2 through power line transmission communication.

Here, as an example, the communication terminal 2 employs high-speed power line communication (HD-PLC: High Definition Power Line Communication) as a method of power line transfer communication. However, the power line transfer communication method of the communication terminal 2 is not limited to high-speed power line communication, and may be, for example, G3-PLC (refer to ITU-T (International Telecommunication Union Telecommunication Standardization Sector) G.9903).

Each of the plurality of communication terminals 2 includes a second communication unit 22 , a control unit 23 , and a memory unit 24 . In addition, one communication terminal 2 among the plurality of communication terminals 2 functions as a repeater 20 that relays the other communication terminals 2 and the display system 1 . The communication terminal 2 of the repeater 20 further includes a first communication unit 21 .

The first communication unit 21 is a communication interface for communicating with the display system 1 . The first communication unit 21 is configured to be able to communicate with the communication unit 11 of the display system 1 via the network 51 . The first communication unit 21 transmits the status information of each of the plurality of communication terminals 2 (including the repeater 20 ) belonging to the same network 52 to the display system 1 . In the present embodiment, the first communication unit 21 periodically transmits the status information of each of the plurality of communication terminals 2 to the display system 1 . That is, the repeater 20 periodically obtains its own state information and the state information of other communication terminals 2 , and transmits the obtained state information of each of the plurality of communication terminals 2 to the display system 1 . In addition, the first communication unit 21 can transmit the updated status information of the communication terminal 2 to the display system 1 when the status information of any one of the communication terminals 2 is updated. In this case, the repeater 20 obtains the status information from the communication terminal 2 whose status information is updated, and sends the obtained status information to the display system 1 .

The second communication unit 22 is a communication interface for communicating with other communication terminals 2 belonging to the same network 52 . The second communication unit 22 is configured to be able to communicate with the second communication unit 22 of the other communication terminal 2 by the power line transfer communication method. In the present embodiment, the second communication unit 22 is configured to be able to communicate with the second communication unit 22 of the other communication terminal 2 by a single-hop method or a multi-hop method. Moreover, the 2nd communication part 22 may be comprised so that it can communicate with the 2nd communication part 22 of the other communication terminal 2 by the wired communication method other than the power line conveyance communication method, or the wireless communication method.

The control unit 23 is constituted by, for example, a computer system having a processor and a memory. Then, when the processor executes the program stored in the memory, the computer system functions as the control unit 23 . The program executed by the processor is pre-recorded in the memory of the computer system, but it can also be recorded in a non-transitory recording medium such as a memory card and provided, and can also be provided through an electrical communication line such as the Internet.

The control unit 23 has a function of sending and receiving data between other communication terminals 2 belonging to the same network 52 via the second communication unit 22 . In addition, the control unit 23 calculates the distance between the adjacent other communication terminal 2 (here, the other communication terminal 2 which is the source of the data) based on the size of the data acquired by the second communication unit 22 and the time required to acquire the data. communication speed between them. The control unit 23 stores the calculated communication speed in the memory unit 24 as status information.

The memory portion 24 includes a rewritable nonvolatile memory such as EEPROM. The storage unit 24 stores status information of the communication terminal 2 . The state information includes, for example, the identification code of the other adjacent communication terminal 2 , the communication speed with the adjacent other communication terminal 2 , and the number of hops, and one or more parameters indicating the communication state of the communication terminal 2 . The memory portion 24 may be a built-in memory of the control portion 23 .

(3) Action Hereinafter, an example of the operation of the display system 1 of the present embodiment will be described with reference to FIG. 2 . Hereinafter, the description will focus on one communication terminal 2 among the plurality of communication terminals 2 belonging to the same network 52 . First, if the processing unit 12 of the display system 1 obtains the position information of the communication terminal 2 from the communication unit 11, the obtained position information is associated with the identification code of the communication terminal 2 and stored in the memory unit 13 (S1). In the present embodiment, as described above, the position information of the communication terminal 2 is pre-stored in the memory unit 13 by the input of the operator of the display system 1 . For example, when the location information of the communication terminal 2 is updated such as changing the installation location of the communication terminal 2 ( S2 : No (No)), the processing unit 12 updates the memory in the memory by acquiring the updated location information of the communication terminal 2 The location information of the communication terminal 2 of the part 13.

Next, the processing unit 12 acquires the status information of the communication terminal 2, associates the acquired status information with the identification code of the communication terminal 2, and stores it in the memory unit 13 (S2: Yes, and S3). In the present embodiment, as described above, the repeater 20 periodically transmits the status information of each of the plurality of communication terminals 2 (including the repeater 20 ) to the display system 1 . Therefore, in this embodiment, the processing unit 12 periodically updates the status information of the passing terminal 2 stored in the memory unit 13 . The order of the above steps S1, S2 and step S3 can be reversed.

Next, if a trigger command (here, a command from the display device 4 operated by the user) occurs ( S4 : Yes), the processing unit 12 reads out the location information and status information of the communication terminal 2 from the memory unit 13 . The above steps S1-S3 and step S4 can be reversed in order. Next, the processing unit 12 outputs the read information and an instruction to reflect the read information on the map information to the display device 4 (S5). The display device 4 receiving the information and command from the display system 1 reflects the position information and status information of the communication terminal 2 to the map information, and displays the reflected map information on the display unit 41 (S6).

Specifically, the display device 4 displays an icon representing the communication terminal 2 on the map displayed on the display unit 41 in the map information based on the position information of the communication terminal 2 . Further, the display device 4 displays a line connecting the communication terminal 2 and other communication terminals 2 adjacent to the communication terminal 2 based on the status information of the communication terminal 2 . Furthermore, based on the state information of the communication terminal 2, the display device 4 displays the text string (or the communication state) indicating the communication state (such as the communication speed, etc.) of the communication terminal 2 in a manner near or overlapping the icon indicating the communication terminal 2 chart) are displayed. At this time, the text string is displayed at a position where it is easy to grasp the situation corresponding to the icon. For example, when the text string is displayed at a position far from the icon, it is difficult for the user to grasp the correspondence between the icon and the text string. On the other hand, when the text string is displayed near the icon or overlapped with the icon, the user can easily grasp the correspondence between the icon and the text string. In this way, the map information reflecting the position information of the communication terminal 2 and the state information corresponding to the position information is displayed on the display unit 41 as an image.

Examples of the images displayed on the display unit 41 include images shown in the first display example, the second display example, and the third display example shown in each of FIGS. 3 to 5 . Of course, the image displayed on the display unit 41 is not limited to the image shown in these display examples. In addition, the image shown in each of FIG. 3-FIG. 5 may be a part of the image displayed on the whole display part 41, and may be all.

In the first display example, as shown in FIG. 3 , the display unit 41 displays a map M1 that simulates a three-dimensional representation of a building, a road, or the like on a plane. That is, in the first display example, the map information is the map M1 represented by the three-dimensional coordinate system. In the first display example, two icons A1 and A2 representing the quadrangular shape of the repeater 20 and ten icons B1 to B10 representing the circular shape of the communication terminal 2 are displayed on the map M1 .

In the building on the left in the map M1, one repeater 20 indicated by the icon A1 and four communication terminals 2 indicated by the icons B1 to B4 are installed. The icon A1 and the icons B1 to B4 are connected by lines, respectively, and the communication terminals 2 constitute one network 52 . In the vicinity of the line connecting the adjacent icons, a text string indicating the communication speed between two communication terminals 2 adjacent to each other (for example, "100 Mbps"), and a distance indicating the distance between the communication terminals 2 are displayed. A literal string (eg "10 m"). Therefore, by observing the text string located near the line connecting, for example, the icons B3 and B4, the user can grasp the positions of the two communication terminals 2 indicated by the icons B3 and B4, the communication speed between the communication terminals 2, and the The distance between the communication terminals 2 is equal.

In addition, in the building on the right in the map M1, one repeater 20 indicated by the icon A2 and six communication terminals 2 indicated by the icons B5 to B10 are installed. The icon A1 and the icons B5 to B10 are connected by lines, respectively, and the communication terminals 2 constitute one network 52 . In the vicinity of the line connecting the adjacent icons, a character string indicating the communication speed between the two communication terminals 2 adjacent to each other and a character string indicating the distance between the communication terminals 2 are displayed.

Here, in the first display example, the two communication terminals 2 indicated by the icons B7 and B9 are connected by a dotted line instead of a solid line. The dotted line indicates that the communication speed between two communication terminals 2 adjacent to each other (here, "20 Mbps") is slower than the communication speed between other two communication terminals 2 adjacent to each other (here, "100 Mbps" or " 120 Mbps”). In this way, in the present embodiment, the processing unit 12 can change the display state in the display unit 41 according to the status information (here, the communication speed between the two communication terminals 2 adjacent to each other).

Therefore, the user can suspect that some abnormality may have occurred in any one of the two communication terminals 2 represented by the icons B7 and B9 by looking at the dotted lines. Here, the user can grasp that the distance between the two communication terminals 2 represented by the icons B7 and B9 (here, "50 m") is longer than the other two communication terminals adjacent to each other by viewing the text string indicating the distance The distance between 2 (here, "10 m"). Therefore, the user can judge that there is a possibility that the communication speed may decrease due to the distance between the two communication terminals 2 indicated by the icons B7 and B9.

In the second display example, as shown in FIG. 4A , the display unit 41 displays a map showing buildings, roads, and the like on a plane. That is, in the second display example, the map information is a map represented by a two-dimensional coordinate system. In the second display example, three icons C1 to C3 representing the square shape in which the communication terminal 2 is installed are displayed on the map M2. A number indicating the number of the installed communication terminals 2 is displayed on each of the icons C1 to C3. For example, the icon C1 indicates that 100 communication terminals 2 are installed in the building indicated by the icon C1.

In the map M2 shown in FIG. 4A , if the user selects any of the icons C1 to C3 , the display unit 41 changes the display state as shown in FIG. 4B . For example, when an input device such as a mouse is used, or the display unit 41 is a touch panel type display, the user can select the icons C1 to C3 by touching the icons C1 to C3. Next, if the icon C1 is selected, for example, as shown in FIG. 4B , the window W1 is displayed near the icon C1. Position information and status information of one or more communication terminals 2 installed in the building indicated by the icon C1 are displayed on the inner side of the window W1. Here, in the window W1, the height information ("Height") of the communication terminal 2 and the communication speed ("Speed") between the communication terminal 2 and other communication terminals 2 are converted to the identification code of the communication terminal 2 ("Device ID: Device ID") to establish a correspondence and display. Therefore, the user can grasp the position and the communication speed of one or more communication terminals 2 installed in the building indicated by the icon C1 by viewing the window W1.

In the first display example (or the second display example), when the area displayed on the display unit 41 is changed by the user's operation, the position information of one or more communication terminals 2 located in the changed area is and status information is displayed on the map M1 (or the map M2). The "area change" referred to here includes not only changing the area displayed on the display unit 41 without changing the scale, but also changing the area displayed on the display unit 41 by changing the scale.

In the 3rd display example, as shown in FIG. 5, the display part 41 displays the electrical system diagram M3 which shows the connection state of one or more communication terminals 2 in the building F1. That is, in the third display example, the map information is the electrical system diagram M3 showing the connection state of the communication terminal 2 . The electrical system diagram M3 may be a diagram showing the inside of the house or a diagram showing the outside of the house. That is, the electrical system diagram M3 can represent, for example, the connection status of the communication terminals 2 distributed in a specific area.

In the third display example, the electrical system diagram M3 shows a four-story building F1 having a basement, the repeater 20 represented by the icon D1, and the four communication terminals 2 represented by the icons E1 to E4. The icon D1 is overlapped and displayed with the icon G1 representing the distribution board located in the basement. Icons E1 to E4 are displayed in an overlapping manner with icons H1 to H4 representing electrical equipment located on each layer, respectively. The icon D1 and the icons E1 to E4 are connected by lines, respectively, and these communication terminals 2 constitute one network 52 . In the vicinity of the line connecting the icons adjacent to each other, a character string indicating the communication speed between the two communication terminals 2 adjacent to each other is displayed. Therefore, by observing, for example, the icons E2 and E3 and the text strings located near the line connecting the icons E2 and E3, the user can grasp the positions of the two communication terminals 2 represented by the icons E2 and E3 and the positions of the communication terminals 2 communication speed between them.

Here, in the third display example, the two communication terminals 2 indicated by the icons E3 and E4 are connected by a dotted line instead of a solid line. Therefore, the user can suspect that some abnormality may have occurred in any one of the two communication terminals 2 represented by the icons E3 and E4 by looking at the dotted lines.

As described above, in the present embodiment, the display unit 41 displays map information corresponding to the position of the communication terminal 2 and the communication state of the communication terminal 2 . Therefore, in the present embodiment, there is an advantage of being easy to grasp the communication state of the communication terminal 2 . For example, when there is a communication terminal 2 in an abnormal communication state (in other words, a communication failure occurs), the user can grasp the position of the communication terminal 2 by viewing the display portion 41 . In addition, the user can grasp whether the communication failure is caused by the abnormality of the communication terminal 2, the state of the installation location of the communication terminal 2, or other reasons by looking at the display unit 41. In this way, in the present embodiment, by visualizing the position and communication state of the communication terminal 2, there is an advantage that the cause of the occurrence of the communication failure can be easily identified, and the need for restoration work on site can be easily determined. Therefore, in the present embodiment, there is an advantage that it is easy for the managers (users) of the networks 51 and 52 to efficiently perform maintenance work such as analysis of the cause when the communication state deteriorates, or repair support. The present embodiment is particularly effective when there are, for example, tens of thousands or hundreds of thousands of communication terminals 2 to be monitored, since the positions and communication states of the communication terminals 2 can be visualized.

In addition, in this embodiment, the position information of the communication terminal 2 includes altitude information. Here, when the position information of the communication terminal 2 does not include the altitude information, the following problems may occur. That is, when communication is performed between a plurality of communication terminals 2 by means of power line transmission, it is assumed that the plurality of communication terminals 2 are installed in a high-rise building, a building with a basement, or the like. In this case, if the positions of the plurality of communication terminals 2 are displayed on the display unit 41 regardless of the altitude information of the communication terminals 2, the plurality of communication terminals 2 existing in the same building will be concentrated at almost one point on the map. and display. Therefore, in this case, even if a communication failure occurs in any one of the plurality of communication terminals 2, it is difficult to identify which communication terminal 2 has a communication failure. In addition, since the noise generated in the communication path also affects the communication state of the communication terminals 2, if a plurality of communication terminals 2 are concentrated and displayed at one point, it is difficult to realize the visualization of the communication path, and it is difficult to specify which one Noise has occurred in the communication path.

On the other hand, in this embodiment, the position information of the communication terminal 2 includes altitude information. Therefore, in the present embodiment, even if a plurality of communication terminals 2 are installed in one building, the plurality of communication terminals 2 can be displayed on the display unit 41 in a form that can distinguish them. Therefore, in the present embodiment, even when a communication failure occurs in any one of the plurality of communication terminals 2 or when noise occurs in the communication path, it is easy to identify which communication terminal 2 has a communication failure. , or which communication path has the advantage of noise.

Furthermore, in the present embodiment, since the position information of the communication terminal 2 includes the altitude information, there is an advantage that the distance between the plurality of communication terminals 2 existing in the same building can be easily calculated. That is, when the position information of the communication terminal 2 does not include the altitude information, since the plurality of communication terminals 2 existing in the same building are located at the same or almost the same coordinates (latitude, longitude), it is difficult to calculate the communication between the plurality of communication terminals 2 Distance between terminals 2. On the other hand, in the present embodiment, since the plurality of communication terminals 2 are located at mutually different coordinates (latitude, longitude, and altitude), the distance between the plurality of communication terminals 2 can be calculated based on the coordinates.

(4) Variation example Hereinafter, a modification example of the above-mentioned embodiment will be listed. The variations described below can be applied in combination as appropriate.

(4.1) The first variation The display system 1 of the first modification is different from the display system 1 of the above-described embodiment in that it further includes a determination unit 14 as shown in FIG. 6A . In this modification, the determination unit 14 is realized as one function of the processing unit 12 .

The determination unit 14 determines the communication state of the communication terminal 2 based on the correlation between the position information and the state information. For example, the determination unit 14 determines whether a communication failure occurs due to any one of the communication terminals 2 based on the distance between the two communication terminals 2 adjacent to each other and the communication speed with the communication terminals 2 .
