This disclosure generally relates to a display system and a display method, and more specifically, to a display system and a display method that communicate with a fixed-type communication terminal.

Document 1 (Japanese Patent Application Laid-Open No. 2010-157983) discloses a remote inspection usage system in which a plurality of electric power measuring devices are arranged in a building such as a collective house. The electric power measuring device is installed in the household and measures the electricity consumed by the household. The system includes: a terminal that obtains measurement data from a power measurement device; and a master that collects measurement data obtained by the terminal through power line communication. The master communicates with a server managed by the power company through a network such as the Internet. With this, the server individually obtains the power usage of each household.

In the system described in Document 1, a communication terminal is a terminal and a communication terminal is a parent machine. However, it is difficult for the administrator of the system to grasp the communication status of the network, that is, the communication status of the communication terminal. As a result, there is a problem that it is not possible to effectively analyze the causes of the deterioration of the communication status, or to perform maintenance operations such as repairing.

Hereinafter, the relationship between the communication terminal 2 and the display system 1 belonging to one network 52 among the one or more networks 52 will be described in detail. Since the relationship between the communication terminal 2 and the display system 1 belonging to the remaining network 52 is the same as that described above, the description is omitted.

The display system 1 includes a communication section (acquisition section) 11 and a processing section 12.

The communication unit 11 obtains state information indicating the communication state of the communication terminal 2 by communicating with the fixed-type communication terminal 2.

Here, in the present embodiment, the display system 1 is configured to be able to communicate with a display device 4 including a display unit 41. The display unit 41 is a thin display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. In this embodiment, the display device 4 is a personal computer (desktop, laptop, etc.). The display device 4 is not limited to a personal computer, and may be a mobile information terminal such as a smart phone or a tablet terminal, or a device such as a smart television.
(2.1) Display System First, the display system 1 will be described. In the present embodiment, the display system 1 is a server and is installed at a place away from the building where the communication terminal 2 is installed, for example, a facility owned by the provider of the communication terminal 2 or a provider using the service of the communication terminal 2. The display system 1 includes a memory unit 13 in addition to the communication unit (acquisition unit) 11 and the processing unit 12.

The communication section 11 is a communication interface for communicating with the communication terminal 2. The communication unit 11 is configured to be able to communicate with a first communication unit 21 (to be described later) of the communication terminal 2 via a network 51 such as a WAN (Wide Area Network) or a LAN (Local Area Network). The network 51 may be a wired communication network or a wireless communication network. Further, the network 51 may be a network composed of a wired communication network and a wireless communication network. The communication unit 11 obtains state information memorized by the communication terminal 2 by communicating with the first communication unit 21 of the communication terminal 2 (here, the repeater 20) via the network 51. The acquired status information is associated with the identification code of the communication terminal 2 which is the source of the status information, and is stored in the storage unit 13.

The processing unit 12 is configured by, for example, a computer system including a processor and a memory. The processor executes the program stored in the memory, so that the computer system functions as the processing unit 12. The program executed by the processor is recorded in the memory of the computer system in advance here, but it can also be provided in a non-transitory recording medium such as a memory card and provided through an electrical communication line such as the Internet.

The processing unit 12 associates and stores the position information of the communication terminal 2 with the state information of the communication terminal obtained by the communication unit 11 in the storage unit 13. That is, the processing unit 12 associates the location information of the communication terminal 2 with the status information of the communication terminal 2 with the identification code of the communication terminal 2 and stores the information in the storage unit 13. In this embodiment, the position information of the communication terminal 2 is input by the operator of the display system 1 and is stored in the storage unit 13 in advance.

In this embodiment, the position information includes coordinate information (latitude, longitude, and altitude) indicating the position of the communication terminal 2. That is, in the present embodiment, the position information includes information indicating the height at which the communication terminal 2 is located with respect to the reference position (hereinafter also referred to as "height information"). The so-called “reference position” in the present disclosure may be a position that becomes a reference for the height at which the communication terminal 2 is located, and may be, for example, the sea surface or the installation surface of a building in which the communication terminal 2 is installed.

In addition, the processing unit 12 reads the position information of the communication terminal 2 and the state information corresponding to the position information from the memory unit 13 according to the trigger instruction, and reflects the read information and an instruction to reflect the read information to the map information. The instruction is output to, for example, the display device 4. The trigger instruction is, for example, an instruction sent from the display device 4 to the display system 1 by the user operating the display device 4. The display device 4 reflects the position information and status information of the communication terminal 2 received from the processing section 12 to map information according to an instruction received from the processing section 12, and displays the reflected map information on the display section 41. In other words, it can be said that the processing unit 12 outputs the location information and status information of the communication terminal 2 to the display device 4 and maps the location information indicating the location of the communication terminal 2 to the map information and the status information obtained by the acquisition unit 11. And displayed on the display section 41. The map information includes a setting area of the communication terminal 2.

In this embodiment, the map information may be, for example, an electronic map created with a Geographic Information System (GIS), or it may be an electronic map provided for paid or free use, for example, via a network such as the Internet. In the former case, it is preferable that the map information is stored in advance by the display device 4. In the latter case, it is preferable that the map information is appropriately obtained by the display device 4 through a network such as the Internet in accordance with a user operation.

The memory unit 13 includes a rewritable non-volatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 13 stores the correspondence between the position information of the communication terminal 2 and the state information of the communication terminal 2 and the identification code of the communication terminal 2 in correspondence. The status information includes, for example, identification codes of other communication terminals 2 adjacent to each other (communication with each other), communication speed between the other communication terminals 2 adjacent to each other, and the number of hops (can be any of single and multiple hops). One or more parameters of the communication state of the communication terminal 2. In this embodiment, the position information includes the distance (ie, communication distance) between two communication terminals 2 adjacent to each other. The communication distance is calculated by the processing unit 12 based on the position information of the communication terminal 2, for example. The memory section 13 may be a built-in memory of the processing section 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, the communication terminal 2 is different from a mobile communication terminal owned by a user such as a smart phone, and does not move from the place where it is installed as long as the situation such as changing the place of installation does not occur. In this embodiment, a plurality of communication terminals 2 are electrically connected to one power line 3. Here, if the power distribution method is a single-phase three-wire type, a group of power lines composed of three lines (three wires) of L1, L2, and N is set as one power line 3. Similarly, if the power distribution method is a single-phase two-wire type, a group of power lines consisting of two wires (two wires) is set to one power line 3, and if the power distribution method is a three-phase four-wire type, then four wires (4 One set of power lines constitutes one 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 another communication terminal 2 by carrying out communication through a power line.

Here, as an example, the communication terminal 2 uses a high-definition power line communication (HD-PLC: High Definition Power Line Communication) as a power line transport communication method. 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 of 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 sends status information of each of a plurality of communication terminals 2 (including the repeater 20) belonging to the same network 52 to the display system 1. In this embodiment, the first communication unit 21 periodically sends status information of each of the plurality of communication terminals 2 to the display system 1. That is, the repeater 20 periodically obtains the status information of itself and the status information of the other communication terminals 2, and sends the obtained status information of each of the plurality of communication terminals 2 to the display system 1. The first communication unit 21 may send the updated status information of the communication terminal 2 to the display system 1 when the status information of any one communication terminal 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. The second communication unit 22 may be configured to communicate with the second communication unit 22 of another communication terminal 2 by a wired communication method other than the power line transport communication method or a wireless communication method.

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

The control unit 23 has a function of transmitting and receiving data to and from 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 communication terminal 2 adjacent to the other communication terminal 2 (here, the other communication terminal 2 where the data is transmitted) based on the size of the data acquired by the second communication unit 22 and the time required to acquire the data. Communication speed. The control unit 23 stores the calculated communication speed in the storage unit 24 as state information.

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

(3) Operation Hereinafter, an example of the operation of the display system 1 according to this embodiment will be described using FIG. 2. The following description focuses 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 through the communication unit 11, the acquired position information is associated with the identification code of the communication terminal 2 and stored in the storage unit 13 (S1). In the present embodiment, as described above, the position information of the communication terminal 2 is stored in the storage unit 13 in advance by the input of the operator of the display system 1. For example, when changing the location information of the communication terminal 2 such as the installation location of the communication terminal 2 (S2: No), the processing unit 12 updates and stores the updated information in the memory by acquiring the updated location information of the communication terminal 2. Location information of the communication terminal 2 of the unit 13.

Next, the processing unit 12 obtains the status information of the communication terminal 2, and associates the obtained status information with the identification code of the communication terminal 2 and stores them in the storage unit 13 (S2: Yes, and S3). In this embodiment, as described above, the repeater 20 periodically sends 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 state information of the passage terminal 2 stored in the storage unit 13. The sequence of the above steps S1, S2 and step S3 may be reversed.

Then, if a trigger instruction (here, the instruction from the display device 4 operated by the user) occurs (S4: YES), the processing section 12 reads the position information and status information of the communication terminal 2 from the memory section 13. The above steps S1 to S3 may be reversed from the order of step S4. Next, the processing unit 12 outputs the read information to the display device 4 and an instruction to reflect the read information to the map information (S5). The display device 4 that has received the information and instructions from the display system 1 reflects the position information and status information of the communication terminal 2 to map information, and displays the reflected map information on the display section 41 (S6).

Specifically, based on the position information of the communication terminal 2, the display device 4 displays an icon indicating the passage of the letter terminal 2 on the map displayed on the display section 41 in the map information. The display device 4 displays lines 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 status information of the communication terminal 2, the display device 4 performs a text string (or a display of the communication status (e.g., communication speed, etc.) of the communication terminal 2 in the vicinity of or overlapping the icon indicating the communication terminal 2 Chart). At this time, the character string is displayed at a position where it is easy to grasp the situation corresponding to the icon. For example, when a character string is displayed away from the icon, it is difficult for the user to grasp the correspondence between the icon and the character string. On the other hand, when a character string is displayed in the vicinity of the icon or superimposed on the icon, the user can easily grasp the correspondence between the icon and the character string. In this way, the map information reflecting the position information of the communication terminal 2 and the status information corresponding to the position information is displayed as an image on the display section 41.

Examples of the image 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 FIGS. 3 to 5, respectively. Of course, the image displayed on the display section 41 is not limited to the images shown in these display examples. The image shown in each of FIGS. 3 to 5 may be a part of the image displayed on the entire display unit 41 or may be all.

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

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

Further, on the building on the right side in the map M1, one repeater 20 indicated by icon A2 and six communication terminals 2 indicated by icons B5 to B10 are provided. The icons A1 and B5 to B10 are connected by lines, and the communication terminals 2 constitute a network 52. Near the line connecting the icons adjacent to each other, a text string indicating the communication speed between two communication terminals 2 adjacent to each other and a text string indicating the distance between these 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 "). Thus, in this embodiment, the processing unit 12 may change the display state in the display unit 41 according to the status information (here, the communication speed between two communication terminals 2 adjacent to each other).

Therefore, the user can suspect that any abnormality may occur in any of the two communication terminals 2 indicated by the icons B7 and B9 by viewing the dotted line. Here, the user can grasp the distance between the two communication terminals indicated by the icons B7 and B9 (here, "50 m") by looking at the text string indicating the distance, which is longer than other two communication terminals adjacent to each other. The distance between the two (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 in 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 showing a quadrangular shape in which the communication terminal 2 is provided are displayed on the map M2. A number indicating the number of communication terminals 2 installed 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 shown 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 section 41 changes the display state as shown in FIG. 4B. For example, if an input device such as a mouse is used or the display portion 41 is a touch panel type display, the user can select the icons C1 to C3 by touching the icons C1 to C3. Next, for example, if the icon C1 is selected, as shown in FIG. 4B, a window W1 is displayed near the icon C1. Position information and status information of one or more communication terminals 2 provided in the building shown by icon C1 are displayed inside 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 identified by the identification code of the communication terminal 2 ("Device ID: Device ID ") is mapped and displayed. Therefore, the user can grasp the position and communication speed of one or more communication terminals 2 installed in the building shown 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 section 41 is changed by the user's operation, the position information of one or more communication terminals 2 located in the changed area is displayed. And status information is displayed on map M1 (or map M2). The “region change” referred to here includes a case where the area displayed on the display section 41 is changed by changing the scale, in addition to a case where the area displayed on the display section 41 is changed without changing the scale.

In the third display example, as shown in FIG. 5, the display unit 41 displays an electrical system diagram M3 showing the connection status of one or more communication terminals 2 in the building F1. That is, in the third display example, the map information is an electrical system map M3 showing the connection status 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 map M3 may indicate, for example, the connection status of the communication terminals 2 distributed in a specific area.

In the third display example, a four-storey building with a basement F1, a repeater 20 indicated by the icon D1, and four communication terminals 2 indicated by the icons E1 to E4 are shown in the electrical system diagram M3. The icon D1 is superimposed on the icon G1 indicating the distribution board located in the basement. The icons E1 to E4 are superimposed on the icons H1 to H4 indicating the electrical equipment located on each floor. The icons D1 and E1 to E4 are connected by lines, respectively, and the communication terminals 2 constitute a network 52. A text string indicating a communication speed between two communication terminals 2 adjacent to each other is displayed near a line connecting the icons adjacent to each other. Therefore, by observing, for example, the icons E2 and E3 and a text string near the line connecting the icons E2 and E3, the user can grasp the positions of the two communication terminals 2 indicated by the icons E2 and E3 and the communication terminals 2 Communication speed.

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

As described above, in the present embodiment, the map information corresponding to the position of the communication terminal 2 and the communication state of the communication terminal 2 is displayed on the display unit 41. Therefore, in this embodiment, there is an advantage that it is easy to grasp the communication state of the communication terminal 2. For example, when the communication terminal 2 has an abnormal communication state (in other words, a communication failure occurs), the user can grasp the position of the communication terminal 2 by looking at the display unit 41. In addition, the user can grasp whether the cause of the communication failure is caused by the abnormality of the communication terminal 2 or the state of the installation part of the communication terminal 2 or other reasons by observing the display unit 41. As described above, in this embodiment, by visualizing the position and communication state of the communication terminal 2, there are advantages in that it is easy to specify the cause of the occurrence of a communication obstacle and it is easy to determine whether a restoration operation is required on site. Therefore, in the present embodiment, there is an advantage that maintenance managers such as easy-to-use managers (users) of the networks 51 and 52 can effectively analyze the causes of deterioration of the communication status, or perform maintenance operations such as repair. This embodiment is particularly effective when the number of communication terminals 2 to be monitored is, for example, tens of thousands or hundreds of thousands, since the positions and communication states of the communication terminals 2 can be visualized.

In this embodiment, the position information of the communication terminal 2 includes height information. Here, when the position information of the communication terminal 2 does not include height information, the following problems may occur. That is, in a case where communication is carried out between a plurality of communication terminals 2 by power line communication, it is assumed that the plurality of communication terminals 2 are installed in a high-rise building or a basement building. In this case, if the positions of the plurality of communication terminals 2 are displayed on the display section 41 without considering the height information of the communication terminal 2, the plurality of communication terminals 2 existing in the same building are concentrated on almost one point on the map While showing. Therefore, in this case, even if communication failure occurs in any of the plurality of communication terminals 2, it is difficult to identify which communication terminal 2 has caused the communication failure. In addition, since the noise occurring in the communication path also affects the communication state of the communication terminal 2, if a plurality of communication terminals 2 are displayed at one point, it is difficult to visualize the communication path, and it is difficult to specify which one Noise occurred on the communication path.

On the other hand, in this embodiment, the position information of the communication terminal 2 includes height 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 so as to be able to distinguish each of them. Therefore, in this embodiment, it is easy to specify which communication terminal 2 has a communication failure even when communication failure occurs in any of a plurality of communication terminals 2 or noise occurs in a communication path. , Or which communication path has the advantage of noise.

Furthermore, in this embodiment, since the position information of the communication terminal 2 includes height information, there is an advantage that it is easy to calculate the distance between a plurality of communication terminals 2 existing in the same building. That is, when the position information of the communication terminal 2 does not include the height information, since the plurality of communication terminals 2 existing in the same building are located at the same or almost the same coordinates (latitude and longitude), it is difficult to calculate the plurality of communication The distance between terminals 2. On the other hand, in this 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) Modification Examples The following describes modification examples of the above embodiment. Modifications described below can be appropriately combined and applied.

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

The determination unit 14 determines the communication status of the communication terminal 2 based on the correlation between the position information and the status 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 two communication terminals 2 adjacent to each other and the communication speed between the two communication terminals 2. Specifically, even if the distance between two communication terminals 2 adjacent to each other is equal to or shorter than the distance between two other communication terminals 2 adjacent to each other, the communication speed between two communication terminals 2 is slower than other Communication speed between two communication terminals 2. In this case, the determination unit 14 may determine that a communication failure has occurred due to at least one of the two communication terminals 2.

The determination result of the determination unit 14 may be displayed on the display unit 41 in an arbitrary display state, or may be transmitted to a mobile terminal held by a user through wireless communication. In either case, the user can send a worker or the like to the installation site of the communication terminal 2 that has determined that a communication failure has occurred to confirm the determination result of the determination unit 14 to restore the communication failure.

(4.2) Second Modified Example In the first modified example, for example, an operator goes to the site and performs appropriate operations such as adjusting a parameter of the communication terminal 2 by inserting a repeater into the communication path, thereby enabling communication. Obstacle recovery. Here, the operator may also adjust the parameters of the communication terminal 2 automatically without going to the scene. As shown in FIG. 6B, the display system 1 of the second modified example is different from the display system 1 of the first modified example in that it includes an adjustment section 15 in addition to the determination section 14. In this modification, the adjustment unit 15 is implemented as one function of the processing unit 12.

The adjustment unit 15 adjusts the parameters of the communication terminal 2 to be determined by the determination unit 14 based on the determination result in the determination unit 14. Here, the adjustment unit 15 adjusts the parameters of the communication terminal 2 determined by the determination unit 14 as having a communication failure. For example, the adjustment unit 15 adjusts the transmission intensity of the signal, the transmission period of the signal, or the reception sensitivity of the antenna of the communication terminal 2 where the communication failure has occurred. The adjustment unit 15 adjusts, for example, the parameters of the communication terminal 2 in which the communication failure has occurred, within the adjustable range of the parameters until the determination result in the determination unit 14 is normal.

In this modification, the parameters of the communication terminal 2 which is the determination target of the determination section 14 are automatically adjusted by the adjustment section 15. Therefore, in this modification, the possibility that the user does not need to perform an operation such as dispatching an operator to the installation site of the communication terminal 2 which has been determined to have a communication obstacle to recover from the communication obstacle, is increased.

(4.3) Other Modifications In the above embodiment, the position information of the communication terminal 2 is stored in the storage unit 13 of the display system 1 in advance by the input of the operator of the display system 1, but there is no intention to limit it. For example, as shown in FIG. 7, when the communication terminal 2 further includes a positioning section 25, the positioning result of the positioning section 25 may be stored in the storage section 13 of the display system 1 as the position information of the communication terminal 2. The positioning unit 25 is configured to measure the position (latitude, longitude, and altitude) of the communication terminal 2 using a satellite positioning system such as GPS (Global Positioning System). The positioning result of the positioning unit 25 is transmitted from the first communication unit 21 to the communication unit 11 of the display system 1 via the network 51, for example. Next, the processing unit 12 of the display system 1 stores the received positioning result of the positioning unit 25 as the position information of the communication terminal 2 in the storage unit 13.

Here, when the communication terminal 2 has the positioning unit 25, it can measure its own position periodically or irregularly. In this case, for example, even if the position of the communication terminal 2 is changed due to several events, the position information of the communication terminal 2 can be automatically updated on the display system 1 by sending the positioning result of the changed communication terminal 2 to the display system 1.

In addition, when the operator who performs the setting operation of the communication terminal 2 holds a mobile terminal having a positioning section equivalent to the positioning section 25 described above, the positioning result of the positioning section can be stored on the display as the position information of the communication terminal 2 The memory section 13 of the system 1. For example, after the setting operation of the communication terminal 2, the operator operates the mobile terminal, and thereby the positioning unit measures the position of the set communication terminal 2. Subsequently, the positioning result of the positioning section is transmitted from the mobile terminal to the communication section 11 of the display system 1 via the network 51 by the operator operating the mobile terminal. Next, the processing unit 12 of the display system 1 stores the received positioning result of the positioning unit in the storage unit 13 as the position information of the communication terminal 2.

In the above embodiment, the processing unit 12 changes the type (solid line or dotted line) of the line representing the icons of the communication terminals 2 according to the communication speed between the two communication terminals 2 adjacent to each other, but it is not limited to them. Of interest. For example, the processing unit 12 may change the other display states such as the color of the line connecting the icons indicating the communication terminals 2 according to the communication speed between two communication terminals 2 adjacent to each other to express the communication status. Moreover, in the above-mentioned embodiment, the processing unit 12 does not necessarily have a function of changing the display state according to the state information. That is, the processing unit 12 may display the state information on the display unit 41 in a display state without being limited to the state information.

For example, in the case where the positions of the plurality of communication terminals 2 are displayed on a map, if the positions of the plurality of communication terminals 2 can be distinguished only by the latitude and longitude of the plurality of communication terminals 2, height information is not required.

In the above embodiment, the display system 1 outputs the information including the position information and the status information and the instruction to reflect the information to the map information to the display device 4, but it is not intended to limit it. For example, the display system 1 may store the map information in the storage unit 13 and output the map information reflecting the position information and status information to the display device 4. In this case, the display device 4 only needs to display the map information received from the display system 1 on the display unit 14. That is, the display system 1 may have map information, and the map information provided in the display device 4 may also be used.

In the above embodiment, one communication terminal 2 (repeater 20) of the plurality of communication terminals 2 includes the first communication unit 21, but there is no intention to limit it. For example, each of the plurality of communication terminals 2 may include a first communication unit 21. In this case, each of the plurality of communication terminals 2 can communicate with the communication unit 11 of the display system 1 via the network 51 to send status information to the display system 1.

In the above embodiment, the processing unit 12 outputs the position information and status information of the communication terminal 2 to the display device 4 by using the user-operated instruction from the display device 4 as a trigger instruction, but it is not intended to limit it. For example, the trigger instruction may be periodically generated by the display system 1. That is, the processing unit 12 may periodically output the position information and status information of the communication terminal 2 to the display device 4. In addition, the processing unit 12 may update any of the position information and status information as a trigger command, and output the position information and status information of the communication terminal 2 to the display device 4.

In the above embodiment, the communication terminal 2 has a function of transmitting status information to the display system 1, but may further have other functions. For example, the communication terminal 2 may have a function of being used in conjunction with a measurement device that measures the amount of electricity used in a customer's facility. In this case, the communication terminal 2 may be installed in the vicinity of the measurement device, and has a function of receiving the power amount data measured by the measurement device and sending it to the display system 1 or a system different from the display system 1 (for example, a data collection system). In addition, for example, the communication terminal 2 may have a function of being used in conjunction with a sensor. In this case, the communication terminal 2 may be disposed near the sensor, and has a function of receiving a detection result detected by the sensor and sending it to the display system 1 or a system different from the display system 1. That is, the communication terminal 2 may have a function of being used in combination with other devices.

As shown above, when the communication terminal 2 is used in combination with other devices, the position information of the other devices can be used as the position information of the communication terminal 2. The reason for this is that the communication terminal 2 is also basically provided near a portion where other devices are provided.

In the above embodiment, the display unit 41 is provided in a display device 4 different from the display system 1. That is, the display unit 41 is not a constituent element of the display system 1, but is not intended to be limited by it. For example, the display unit 41 may be an external display provided in the display system 1. That is, the display system 1 may further include a display unit 41 that displays map information.

In the above embodiment, the display system 1 is used for grasping the communication status of the communication terminal 2 during the operation of the established communication terminal 2, but it is not intended to be limited thereto. For example, the display system 1 may be used at the stage where a plurality of communication terminals 2 are installed and a network 52 is established. In this case, since the setting work of the communication terminal 2 by the operator and the communication status of the set communication terminal 2 with the display system 1 can be performed in parallel, there is a so-called communication status of the network 52 that is easy to obtain The advantages of optimization.
