Databases

5a, 5b,..., 5n are connected to each access point 4, but they are simply referred to as “database 5” when it is not necessary to distinguish them. In this specification, “wireless” means that a signal is transmitted through space by electromagnetic waves.

In this example, the wireless relay device 4 is a wireless LAN (Local Area Network) access point (AP). However, the wireless relay device 4 may be a wireless LAN router. In the following description, it is assumed that the wireless relay device 4 is an access point. As will be described later in detail, the access point 4 acquires information related to the communication status. The acquired information is stored and held in the database 5.

The control unit 30 includes an arithmetic processing circuit such as a CPU. The control unit 30 executes a program stored in the storage unit 60 by a CPU (computer) to realize a function for performing display data generation processing described later. Part or all of the configuration for realizing the functions here is not limited to being realized by software by executing a program, and may be realized by hardware. A case where it is realized by hardware will be described in Modification 1. Note that the functions realized by the control unit 30 include a function of controlling each unit of the apparatus, in addition to a function of generating display data (display data generation function).

The storage unit 60 is a storage device such as a nonvolatile memory or a hard disk. The storage unit 60 includes a storage area for storing application programs for realizing various functions such as the above-described program, and a storage area for storing setting information set by setting processing or the like. The program only needs to be executable by a computer, and may be provided in a state of being stored in a computer-readable recording medium such as a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or a semiconductor memory. In this case, the control device 3 may include a device that reads the recording medium. The program may be downloaded via a network.

The operation unit 40 outputs a signal corresponding to an operation input by the user with an operation button or the like to the control unit 30. The operation button may be, for example, an operator that includes a power switch, a cursor key, and the like and receives a user instruction. The display unit 50 is a display device such as a liquid crystal display or an organic EL display, and displays a screen (such as a setting screen) based on control by the control unit 30. Note that the control device 3 may not have the operation unit 40 and the display unit 50. In this case, functions corresponding to the operation unit 40 and the display unit 50 may be substituted in an external device connected to the control device 3. The connection unit 70 is an interface for connecting to a terminal such as a PC.

The communication unit 80 is connected to a network (not shown) based on the control of the control unit 30, and transmits / receives information to / from an external device. The above is the description of the control device 3.

Next, the configuration of the control unit 30 of the control device 3 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a functional block configuration of a control unit of the control device according to the embodiment of the present invention. The control device 3 includes a reception unit 31 and a generation unit 33. 3 also shows a display unit 50, a storage unit 60, and a communication unit 80 for convenience of explanation.

The receiving unit 31 receives communication status information from a plurality of access points 4. The receiving unit 31 may receive communication status information from the plurality of access points 4 after receiving an input for updating the display contents. Here, the communication status information includes information (first information) indicating communication status related to the access point, information indicating communication status related to the identifier (SSID; Service Set IDentifier) set to the access point (second information). Information) and information (third information) indicating a communication status commonly associated with a plurality of SSIDs (Multi SSIDs) set at the same access point.

The information indicating the communication status related to the access point is, for example, information such as radio wave intensity, channel, number of access points, and the like. Information indicating the communication status related to the SSID set in the access point includes, for example, the SSID, the MAC address of the wireless terminal connected to the SSID, the media type (IEEE 802.11a / b / g / n, etc.), Information such as channel, transmission speed, authentication method (open, PSK, WPA, WPA2, etc.), encryption method, and the like.

Information indicating a communication status commonly associated with a plurality of SSIDs set in the same access point includes, for example, a channel usage rate, a CRC error occurrence rate, a communication load (traffic), and a frequency (in this example, 2.4 GHz and 5 GHz) information such as the number of connected wireless terminals.

The generator 33 includes a plane defined by the X-axis direction (first direction) 701 and the Z-axis direction (second direction) 702, and a Y-axis direction (third direction) different from the X-axis direction 701 and Z-axis direction 702. ) 703 to generate data for pseudo display of the three-dimensional space defined by 703. In addition, the generation unit 33 arranges an image corresponding to an SSID, which will be described later, in the Y-axis direction 703 for each access point 4 for which the SSID is set, and groups them in an X-axis direction 701 as an image group 65 (see FIG. 5). , Data to be displayed at a position corresponding to information indicating the communication status related to the access point along at least one of the Z-axis direction 702 and the Y-axis direction 703 is generated. Further, the generation unit 33 generates data for displaying information indicating a communication status related to the SSID set in the access point corresponding to the SSID in the image corresponding to the SSID. Further, the generation unit 33 is an area corresponding to an image (a representative SSID icon 61 described later) located in the forefront of the image group 65 and is superimposed on an image corresponding to another SSID included in the image group 65. Data for displaying information indicating a communication status commonly associated with a plurality of SSIDs set in the same access point corresponding to the plurality of SSIDs indicated by the image group 65 is generated at a position including at least a region not to be processed. Using the data generated by the generation unit 33, the display unit 50 displays an image.

The generation unit 33 may generate data that pseudo-displays a three-dimensional space defined by the plane and the Y-axis direction (third direction) 703. In this case, the generation unit 33 uses a plane and Y as an image group 65 (see FIG. 5) in which images corresponding to the SSID are arranged and grouped in the Y-axis direction 703 for each access point 4 for which the SSID is set. Data to be displayed at a position corresponding to information indicating the communication status related to the access point is generated in at least one of the axial directions 703. For example, when a channel is displayed in the Y-axis direction 703 and the radio wave intensity and the number of access points are displayed on a plane, the display method on the plane may be any display method. The plane may not be a plane orthogonal to the X axis and the Z axis, and the relationship between the radio wave intensity and the number of access points may be displayed in one direction such as the X axis or the Z axis. Further, the relationship between the radio wave intensity and the number of access points may be displayed on an arbitrary axis (for example, in a spiral shape) on the plane.

Next, the display on the display unit 50 of the control device 3 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of a display unit of the control device according to the embodiment of the present invention.

CH + button 501, CH- button 503, channel selection button 505, search button 509, whole display button 515, enlargement button 517, reduction button 519, up button 521, down button 523, left button 525, and right button 527 shown in FIG. The origin return button 529 and the automatic update button 543 are included in the operation unit 40.

By pressing an entire display button 515, an entire map can be displayed as shown in FIG. When the enlarge button 517 is pressed, the display can be enlarged, and when the reduce button 519 is pressed, the display can be reduced. By pressing the up button 521, the down button 523, the left button 525, and the right button 527, it is possible to designate up, down, left and right respectively. When the origin return button 529 is pressed, the vicinity of the origin is displayed. Further, whether to update the display contents automatically or manually can be selected depending on whether the automatic update button 543 is pressed. Further, when an XY display button (not shown) is pressed, the XY plane can be displayed as the front. Similarly, when the YZ display button (not shown) is pressed, the YZ plane can be displayed as the front, and when the ZX display button (not shown) is pressed, the ZX plane is displayed as the front. Can do. When these planes are the front, the other axes are not displayed. When the button 531 is pressed, the CRC error rate of the frame addressed to the own station is displayed. When the button 533 is pressed, the CRC error rates of all frames received by the access point 4 are displayed.

When the CH + button 501 is pressed, a channel having a value increased by one channel from the currently selected channel is selected. On the other hand, when the CH-button 503 is pressed, a channel having a value obtained by subtracting one channel from the currently selected channel is selected. When a channel selection button 505 is pressed, a channel can be freely selected. Information on channels other than the channel selected by setting may be hidden. A free word can be entered in the search field 511. When the search button 509 is pressed, the search result is displayed in the additional information display field 545. In this example, “SSID-8” is entered in the search field 511. When “SSID-8” is searched, an icon (a representative SSID icon 61 or a sub-SSID icon 62 described later) corresponding to “SSID-8” is displayed in the additional information display field 545.

When the additional information display icon (not shown) is pressed, the comment in the additional information display field 545 may be updated. In the additional information display field 545, “good” and “bad” are described, and there are five rectangles therebetween. The five rectangles may be given different colors or different characters may be described. In this example, the meanings of the five rectangles are “good”, “acceptable”, “caution”, “warning”, and “serious” as viewed from “good”. However, the number and meaning of the rectangles can be set as appropriate.

Note that the evaluation criteria are determined based on the communication status information. The CRC error rate of the channel used by the local station (the control device 3) is equal to or higher than a predetermined percentage, there is a channel that completely overlaps the channel used by the local station, and the channel usage rate is predetermined. It is more than a percentage, the number of wireless terminals connected to the own station is more than a predetermined number, and there is a wireless terminal whose signal reception intensity from the wireless terminal connected to the own station is −70 dBm or less. These conditions may be set, and each condition may be integrated and used as a criterion for evaluation.

As mentioned above, even if the user does not have specialized knowledge, it is possible to display with colors and characters that mean “good”, “acceptable”, “caution”, “warning”, “serious”, etc. There is an effect that the importance of can be determined.

Next, an overall map of the wireless LAN will be described with reference to FIG. FIG. 5 is a conceptual diagram showing an example of an overall map of the control device according to the embodiment of the present invention.

The SSID icon is displayed at a position corresponding to information (first information) indicating a communication status related to the access point for each access point 4 in which the SSID icon is set. The information (first information) indicating the communication status related to the access point is, as described above, the radio wave intensity, the channel, the number of access points, and the like. In the example of FIG. 5, the X-axis direction (first direction) 701 represents the radio wave intensity as the first information, the Y-axis direction (third direction) 703 represents the channel as the first information, and the Z-axis direction. (Second direction) 702 represents the number of access points as the first information. The radio wave intensity means the radio wave intensity viewed from the control device (own station access point) 3. That is, after the icon of the control device (own station access point) 3 is arranged at the origin, the origin is set to 0 dBm, and the farther away from the origin the minus side in the X-axis direction, the farther from the control device (own station access point) 3. This means that the radio field intensity seen is weakened. However, the X-axis direction 701, the Y-axis direction 703, and the Z-axis direction 702 may be not only one of the radio wave intensity, the number of channels, and the number of access points, but the channel usage rate, CRC error rate, and SSID number. When three types of information are displayed in each of the three directions in this way, the generation unit 33 displays data for displaying the image group 65 at positions corresponding to the three types of information along the three directions. Is generated.

5, an image corresponding to the SSID, that is, a representative SSID icon 61, a sub SSID icon 62, and an SSID icon 63 of another company's access point are displayed. The representative SSID icon 61 means a representative SSID icon of VAP (Virtual Access Point). The representative SSID means an SSID displayed on the front side of the screen (the forefront of the screen) among a plurality of SSIDs of the same access point. The sub SSID icon 62 means an icon of an SSID other than the representative SSID. In the case of VAP, it is possible to set a plurality of SSIDs (Multi SSID). It can be said that the representative SSID icon 61 and the sub SSID icon 62 are image groups grouped in the Y-axis direction 703 for each access point.

The display interval between the representative SSID icons 61, the display interval between the representative SSID icon 61 and the sub SSID icon 62, and the display interval between the representative SSID icon 61 and the SSID icon 63 of another company's access point are appropriately set. Can be changed.

When the access point operates with a plurality of SSIDs, a plurality of SSIDs are overlapped in the Y-axis direction 703 and displayed. That is, the sub SSID icon 62 is displayed side by side so as to partially overlap in the Y-axis direction 703 behind the representative SSID icon 61. In other words, the icon 61 of the representative SSID is displayed as a complete icon without being blocked by other icons. On the other hand, the portion of the sub SSID icon 62 that overlaps with the icon in front of the screen is blocked from being displayed, and a complete shape icon is not displayed. The difference between the representative SSID icon 61 and the sub SSID icon 62 will be described in detail in the description of FIGS.

In this example, the representative SSID icon 61 and the sub SSID icon 62 are SSIDs of access points made by the same company. Here, an access point made by the same company may be called an “own access point”. The company access point is the controller access point 3 and the member access point 4 controlled by the controller access point. In this example, the SSID icon of the company access point is displayed on the plus side in the Z-axis direction 702. On the other hand, the SSID icon 63 of another company's access point is displayed on the minus side in the Z-axis direction 702. The SSID icon 63 of another company's access point means the SSID icon of another company's access point that is not controlled by the controller access point 3. Thus, by separately displaying the SSID of the company access point and the SSID icon of the other company's access point, it is possible to distinguish and grasp each information.

Further, by displaying the entire access point map as shown in FIG. 5, there is an effect that the information of all the access points can be grasped at a time without switching the display. The icons displayed on the entire map (representative SSID icon 61, sub SSID icon 62, and SSID icon 63 of another company's access point) each have an evaluation lamp, so that each evaluation can be grasped at a glance. There is an effect. Although details of the evaluation lamp will be described later, in this example, colors corresponding to five evaluation levels are displayed on the evaluation lamp. As described above, by arranging the SSID icon in the pseudo three-dimensional space, it is possible to easily find an SSID having a poor evaluation.

Also, assuming that the X-axis direction 701 is the radio wave intensity, when there are a plurality of SSID icons whose evaluation level is a certain level or less, there is an effect that the cause of the evaluation level being a certain level or less can be visually grasped. That is, when there are a plurality of icons of SSID whose evaluation level is below a certain level and these radio wave intensities are within a predetermined range (for example, the same or close values), it is visually confirmed that there is a high possibility of an external wave or an interference wave. Can be grasped. On the other hand, even if there are multiple SSID icons with an evaluation level below a certain level, if these radio field strengths are outside the specified range, it is possible to visually grasp that the possibility of extraneous waves and interference waves is low Can do.

When there are a plurality of images corresponding to the SSID in a predetermined range according to the communication status information, and the relationship between the information on the radio wave intensity at which the plurality of images is located satisfies the predetermined condition, the generation unit 33 satisfies the predetermined condition. Data for selecting and displaying the image may be generated. Here, the SSID in the predetermined range according to the communication status information may be, for example, an SSID whose evaluation level is a certain level or less. Further, the predetermined condition may be, for example, that the information on the radio field intensity at which the plurality of images are located matches, or the difference in the radio field intensity at which the plurality of images is located is within a predetermined range (for example, 20 dB). May be within. The predetermined condition can be set as appropriate. When there are a plurality of images of SSID with a bad evaluation level and the predetermined condition is that the information on the radio field intensity at which the plurality of images are located coincides, the cause of the bad evaluation level is likely to be an external wave or an interference wave . Therefore, there is an effect that data for selecting and displaying an image of an SSID with a bad evaluation level by an external wave or an interference wave can be generated.

The generation unit 33 displays images corresponding to all SSIDs in the three-dimensional space, and when one of the images corresponding to the SSID is selected, data for displaying the image corresponding to the selected SSID. May be generated. When one of the icons (representative SSID icon 61, sub SSID icon 62, SSID icon 63 of another company's access point) displayed on the entire map is selected, the generation unit 33 displays the selected SSID icon. Data is generated and an icon of the selected SSID is displayed in the additional information display field 545. This produces an effect that the information to be confirmed can be narrowed down. For example, when checking on the entire map, by selecting an icon having a bad evaluation lamp, detailed information of the icon having a bad evaluation can be confirmed.

When any one of a plurality of wireless relay device images is selected, the generation unit 33 generates data for displaying the selected wireless relay device image in a predetermined area. Also good. Specifically, the generation unit 33 displays the selected image of the wireless relay device in the X-axis direction (first direction) 701, the Z-axis direction (second direction) 702, and the Y-axis direction (third direction) 703. Data for display in a region including the centers of the three axes (the origin shown in FIG. 5) may be generated. For example, in a three-dimensional space having three axes of radio field intensity, channel, and SSID number, in the initial state, the SSID icon of the control device (own station access point) 3 has an SSID number of 0 and a radio field intensity of 0 dBm of the channel in operation. The SSID icons are displayed in the order of the radio wave intensity detected by the control device 3 for each channel. When one image of a plurality of access points (member access points) 4 is selected from this initial state, the selected access point 4 is moved to a position where the number of SSIDs of the operating channel is 0 and the radio wave intensity is 0 dBm. The SSID icons are displayed in the order of the radio wave intensity detected by the access point 4. This produces an effect that the information to be confirmed can be narrowed down.

Next, the representative SSID icon 61 and the sub SSID icon 62 will be described with reference to FIGS. 6 and 7 are conceptual diagrams showing examples of icons according to an embodiment of the present invention.

The representative SSID icon 61 is displayed in at least three areas. In this example, the three regions are circular as shown in FIG. However, the shape of the icon 61 of the representative SSID is not limited to a circular shape, and may be any shape that can display a plurality of shapes such as a polygonal shape and an elliptical shape. Among the three areas, the innermost area (first area), for example, in the center 612 of the icon 61 of the representative SSID, information indicating the communication status related to the SSID set for the access point (second information) ) Is displayed. This information may be called basic information. Evaluation is displayed by the evaluation lamp 617 in the second area, which is an area surrounding the first area. The number display 611 is displayed in a third area that is an area surrounding the second area.

Basic information (second information) is information such as SSID, MAC address, wireless LAN standard, channel, maximum transmission rate, authentication method, encryption method, evaluation, and the like as described above. In this example, as shown in FIG. 6, the SSID is SSID-12345678. The MAC address is 12: 34: 56: 78: 90: ab. The wireless LAN standard is IEEE 802. In ac, the channel is 13ch. The maximum transmission speed is 1.7 Gbps, the authentication method is WPA2-EAP, and the encryption method is AES. These pieces of information shown in FIG. 6 are information (second information) indicating the communication status related to the SSID set in the access point.

In this example, the evaluation level is “5”. In this example, there are five evaluation levels, and colors corresponding to the respective evaluations are displayed on the

evaluation lamps

617 and 627. For example, when the evaluation level is “1”, the evaluation is “critical” as described above, and the corresponding color is dark red. When the evaluation level is “2”, the evaluation is the “warning” described above, and the corresponding color is red. When the evaluation level is “3”, the evaluation is “Caution” described above, and the corresponding color is orange. When the evaluation level is “4”, the evaluation is “allowed” as described above, and the corresponding color is green. When the evaluation level is “5”, the evaluation is “good” as described above, and the corresponding color is blue. When the evaluation level is “0”, there is no evaluation result and the lamp is turned off. The stage corresponding to the evaluation level and the color corresponding to the evaluation level can be set and changed as appropriate. The evaluation is determined based on the communication status information as described above.

Number displays 611 and 621 represent the number of wireless terminals to be connected. In this example, the

number display

611 and 621 can display from 0 to 100 units. The color corresponding to the number is also displayed. For example, when the number of connected wireless terminals is 0, the light is turned off, and when the number of connected wireless terminals is 1 to 10, the color is displayed in blue. Similarly, when 11 to 20 units are displayed in green, when 21 to 40 units are displayed in orange, when 41 to 50 units are displayed in red, 51 to 100 are displayed. When using a stand, it is displayed in dark red. However, the number of units that can be displayed on the

unit numbers

611 and 621 and the color corresponding to the number can be set and changed as appropriate.

A region corresponding to the image located in the forefront of the image group and including at least a region not superimposed on another image included in the image group includes a third corresponding to the plurality of SSIDs indicated by the image group. Information (information indicating communication status commonly associated with a plurality of SSIDs set at the same access point) is displayed. In this example, the information indicating the communication status commonly associated with a plurality of SSIDs set at the same access point is a CRC error rate and a channel usage rate. The CRC error rate 613 displays the CRC error rate, and the channel usage rate 615 displays the channel usage rate. The CRC error rate 613 and the channel usage rate 615 shown in FIG. 6 are information (third information) indicating the communication status commonly associated with a plurality of SSIDs set at the same access point. The CRC error rate 613 and the channel usage rate 615 are information that is the same value in a plurality of SSIDs, or information that is commonly related. Since the CRC error rate is calculated for all frames received by one access point, there is no conceptual CRC error rate in SSID units. Therefore, the CRC error rate is information common to a plurality of SSIDs. The channel usage rate is the same because one access point uses the same frequency. Therefore, the channel usage rate is information that has the same value for a plurality of SSIDs. The region corresponding to the image located in the forefront of the image group and including at least a region that is not superimposed on other images included in the image group is not limited to the CRC error rate or the channel usage rate. If the information has the same value in the SSID, or information related in common, it can be displayed.

CRC error rate can be displayed from 0% to 100%. Also, the color corresponding to the percentage can be displayed. In this example, when the CRC error rate is 0%, the light is turned off, and when the CRC error rate is 1% to 10%, it is displayed in blue. Similarly, when the CRC error rate is 11% to 20%, it is displayed in green, and when the CRC error rate is 21% to 40%, it is displayed in orange, and the CRC error rate is 41% to 60%. Is displayed in red, and when the CRC error rate is 61% to 100%, it is displayed in dark red. Similarly to the CRC error rate, the channel usage rate is displayed from 0% to 100% with a color corresponding to the percentage.

5 and 6, the CRC error rate 613 information and the channel usage rate 615 information are displayed on the left half around the evaluation lamp 617. This is because, as shown in FIG. 5, the Y-axis direction 703 is the upper right direction in a plan view, and is displayed on the opposite side to the upper right direction. In this way, what is displayed on the opposite side to the upper right direction is the information that is the same value in a plurality of SSIDs, or if it is common information, it is displayed on the SSID in front of the screen, that is, the icon 61 of the representative SSID. This is because there is no need to display the sub SSID icon 62. Therefore, as shown in FIG. 7, the CRC error rate information and the channel usage rate information are not displayed on the sub SSID icon 62. The representative SSID icon 61 and the sub SSID icon 62 are different in this respect.

The Y axis direction 703 can be set in any direction. For example, unlike the example of FIG. 5, when the Y-axis direction 703 is the upper left direction in the plan view of FIG. 5, the CRC error rate 613 and the channel usage rate 615 are displayed on the right half around the evaluation lamp 617. Is done. That is, the CRC error rate 613 and the channel usage rate 615 are displayed on the side opposite to the direction in which a plurality of SSID icons overlap in the vicinity of the SSID in front of the screen.

For example, when the search is performed by inputting the MAC address of the wireless terminal in the search field 511 shown in FIG. 4, the MAC address information 639 may be displayed outside the circle as shown in FIG. 8A. The display position of the MAC address information is a position that is difficult to overlap with other SSID icons. For example, when the Y-axis direction 703 is changed, the MAC address information is displayed from the position shown in FIG. 8A (the position of the MAC address information 639) to the position shown in FIG. 8B (the position of the MAC address information 649). May change. In this example, as shown in FIGS. 8A and 8B, the MAC address information 639 and the MAC address information 649 have triangle arrows, and these arrows respectively point toward the center of the circle. As described above, when the MAC address of the wireless terminal is searched, the searched MAC address information is displayed, so that it is easy to distinguish from other SSID icons. The display of the MAC address information outside the circle is not limited to the case where the search is performed by inputting the MAC address of the wireless terminal in the search field 511, even when the wireless terminal roams. Good. Further, the display of the MAC address information may be set during a predetermined time.

Note that, similarly to the Y-axis direction 703, the X-axis direction 701 and the Z-axis direction 702 are regions corresponding to the image located at the forefront of the image group, and are not superimposed on other images included in the image group. Any information can be set as long as it is possible to display information having the same value by a plurality of SSIDs or information related in common at a position including at least an area.

On the other hand, the number display 621 is preferably displayed as much as possible even if the sub SSID icon 62 partially overlaps. In the example of FIG. 5, part of the number display overlaps. However, in this example, 1 to 10 units are displayed in blue, 11 to 20 units are displayed in green, 21 to 40 units are displayed in orange, 41 When the number is 50 from the stand, it is displayed in red, and when it is 51 to 100, it is displayed in dark red. Therefore, for example, even if a part of the number display is overlapped, it is possible to identify which of these five colors is displayed. Therefore, it is preferable that the degree of overlap of the sub SSID icons 62 is such that even if they overlap, it is possible to identify which of the evaluation level colors (in this example, five colors) is displayed. The degree of this overlap depends on the number of displayable colors and the color corresponding to the number. In order to display the colors of all the evaluation levels on the number display 621, the generation unit 33 is a region corresponding to an image corresponding to a plurality of SSIDs, and a plurality of regions are provided at positions including at least a region not superimposed on another image. Data for displaying information on the number of connected wireless terminals corresponding to the SSID may be generated.

As described above, according to the present embodiment, there is an effect that information of one SSID can be grasped in real time with one icon without switching the screen display. For example, if the number of wireless terminals connected to the channel usage rate is displayed as in the present embodiment, the cause of the high channel usage rate can be investigated. That is, when the channel usage rate is high and the number of wireless terminals to be connected is large, it may be caused by a large number of wireless terminals to be connected and a load on the access point 4 being applied. On the other hand, when the channel usage rate is high and the number of connected wireless terminals is small, it may be caused by the wireless terminal connected to the access point 4 being in the low speed mode. The wireless terminal connected to the access point 4 has a lower transmission rate if the distance from the access point 4 is increased. If even one wireless terminal has a low transmission speed, the transmission speed of other wireless terminals connected to the access point 4 to which the wireless terminal is connected will also be low. Thus, by displaying a plurality of communication status information such as the channel usage rate and the number of wireless terminals to be connected in one display without switching the screen display, one SSID information is displayed with one icon. There is an effect that it is possible to grasp the problem occurring every time and the cause thereof.

[Operation example]
With reference to FIG. 9, an operation example when the entire map function of the control device 3 is used will be described. FIG. 9 is a flowchart showing an operation example when the entire map function of the control device according to the embodiment of the present invention is used.

First, it is determined whether or not an input for updating display contents has been received from the user (step S101). If this input is not accepted, the process loops until this input is accepted, and when the input is accepted (in the case of Yes in step S101), the control device 3 sends the latest communication status to each access point 4 An instruction is transmitted to transmit information (step S103). The latest communication status information means the communication status information when the record of the communication status information is updated at the access point 4. In other words, it means communication status information having time information (time stamp) when updated. When the automatic update button 543 is pressed, it is treated that an update input is accepted at each set automatic update timing.

Then, the receiving unit 31 receives the latest communication status information from each access point 4 (step S105). In other words, the receiving unit 31 receives the communication status information from the access point 4 after receiving an input for updating the display content. If the receiving unit 31 does not receive the latest communication status information even after the predetermined period has elapsed, the control device 3 may request each access point 4 to retransmit the latest communication status information. Alternatively, the process may be terminated and the user may wait for the input of the display content update from the user again.

Subsequently, the latest communication status information received is recorded in the database 5 (step S107). Subsequently, the generation unit 33 generates data for displaying an icon related to each SSID based on the latest communication status information of each access point 4 recorded in the database 5 (step S109). In this operation example, it has been described that the display unit 50 is outside the control device 3. However, when the control device 3 includes the display unit 50, the display unit 50 further generates data generated by the generation unit 33. May be displayed.

Thus, by displaying information in SSID units in real time, it is possible to grasp the problem that has occurred in each SSID in real time. In addition, since the icons of each SSID are displayed with colors and characters meaning “good”, “acceptable”, “caution”, “warning”, “critical”, etc., even a user who does not have specialized knowledge, The effect is that the importance of the problem can be judged.
