[0016] <Fixture 20> Figure 2 shows an example of the configuration of the fixture 20 in this embodiment. The fixture 20 is a desk equipped with a tabletop 21. The fixture 20 measures the state quantities of the tabletop 21. It is equipped with a sensor 210 that has the function of [doing something].

[0017] The sensor 210 detects the state of the top plate 21. The state of the top plate 21 is the state of the top plate 21. Any state variable related to the load on the plate 21 is acceptable, for example, one resulting from the load on the top plate 21. These are state variables. Examples of such state variables include the load on the top plate 21 itself, and the state of the top plate 21. Distortion, deflection of the top plate 21, etc. are possible causes. Below, the state quantity of the top plate 21 is the deflection of the top plate 21. We will explain the details using deflection information related to the beam as an example.

[0018] For example, a pressure sensor can be used as the sensor 210 for detecting the state of the top plate 21.

It has a memory unit and a sensor 210 that stores the measured deflection information on the network N. The information is transmitted to the information processing device 30 via the sensor 210. Even if you store it in the memory unit and transmit it from the memory unit to the information processing device 30 at a predetermined timing, good.

[0021] Furthermore, the deflection information is not limited to the load applied to the top plate 21, but also includes, for example, the fixture ID and the mounted... The sensor ID of the sensor being used, the user ID of the user who is using the fixture 20, and / or This includes the date and time of data transmission. Furthermore, the deflection information is limited to information regarding the deflection of the top plate 21. For example, if the fixture 20 is a chair or a whiteboard, the deflection information is, for example The data includes deflection information measured by sensors 210 placed on the back of chairs, whiteboards, etc. Furthermore, deflection information is directly communicated, for example, to the information processing device 30 via the network N. Even if the sensors 210 mounted on any reliable fixture 20 measure deflection information, good.

Here, the information processing terminal 50 is configured The computer involved does not necessarily have to be just one; multiple computers distributed across a network N can be used. It may consist of a number of computers.

[0030] Figure 4 is a block diagram showing an example of the functional configuration of information processing terminals 40 and 50. Yes. Information processing terminals 40 and 50 are constructed, for example, by a general-purpose computer. It consists of a control unit 400, a communication unit 500, a storage unit 600, and a user interface. It is composed of S700 and other components.

Send and receive information.

[0035] <Regarding adjustment processing> The following information processing device 30 is used to determine a predetermined outcome based on the deflection information and the result of the situation assessment. The method for adjusting the threshold will be explained in detail. Figure 5 shows the adjustment process in this embodiment. This is a diagram illustrating an example of the above. In this embodiment, first, the information processing device 30 is The system acquires deflection information regarding the deflection of the top plate 21 of the fixture 20, and compares the deflection information with a predetermined threshold. Based on the values, the system estimates the occurrence of an abnormality in the top panel 21. Then, the information processing device 30 estimates the occurrence of an abnormality in the top panel 21. The system obtains information regarding the presence or absence of abnormalities, and combines the deflection information, estimation results, and abnormality information. Based on this, the predetermined threshold is adjusted.

[0036] The first acquisition unit 311 acquires deflection information relating to the deflection of the top plate 21 of the fixture 20. Figure 6 shows an example of the process for acquiring deflection information in this embodiment. In this state, the sensor 210 acquires the load P1(N) applied to the top plate 21. 1. The acquisition unit 311 acquires, for example, the load P1(N) acquired from the sensor 210, and the storage unit 33 Based on the basic information about the top plate 21 that was previously stored in 0, the deflection that occurred in the top plate 21 ( Obtain the length (mm). Basic information about the top plate 21 includes, for example, the shorter side length of the material of the top plate 21. a (mm), longest side length b (mm), plate thickness t (mm), Young's modulus (MPa), and / or pt This includes Ason's ratio, etc. The first acquisition unit 311, for example, takes the deflection (mm) that occurs in the top plate 21. When obtaining the data, the time the sensor 210 received the data, the fixture ID, etc., are used as deflection information. The information is acquired. The acquired deflection information is stored in the storage unit 330 for each fixture ID, for example. It can be done.

[0037] The estimation unit 313 detects abnormalities in the top plate 21 based on the acquired deflection information and a predetermined threshold. The process of estimating the occurrence of an abnormality in the top panel 21 is shown in Figure 7, which illustrates an example of the estimation process.

[0038] In this embodiment, the estimation unit 313 sets a predetermined threshold value, which is a deflection threshold (980(N)). As shown in Figure 7, during period T1, the load P1 obtained from sensor 210 ( Since N) is less than the deflection threshold of 980(N), the estimation unit 313 determines the difference in the top plate 21. Regarding the recurring occurrence, we estimate it to be "no abnormality."

[0039] On the other hand, during period T2, the load P1(N) is greater than or equal to the deflection threshold of 980(N) In some cases, the occurrence of an abnormality in the top panel 21 is estimated to be "abnormal." Estimation section 3 follows. The results regarding the occurrence of anomalies estimated from 13 are also called estimation results. For example, estimation results include: Each fixture ID is stored in the storage unit 330.

[0040] Note that the initial value of the deflection threshold (in this case, "980(N)") is not determined by how to set it. It is optional. Furthermore, the deflection threshold can be a fixed value or it can be changed as appropriate. For example, Depending on the type of furniture 20 (desks, chairs, etc.), the material, weight, and / or size of the tabletop 21, etc. It can be set as desired. Furthermore, the deflection threshold may be set as a multi-level value.

[0041] The second acquisition unit 312 acquires information regarding the presence or absence of abnormalities in the top plate 21 of the fixture 20. To acquire. For example, if a camera is installed around the fixture 20, the second acquisition unit 312 will acquire the data. The video footage captured by the camera will be received.

[0042] The second acquisition unit 312, for example, from the received video, generates on the top plate 21 of the fixture 20. The second acquisition unit 312 recognizes the fatigue condition of the top panel 21, such as cracks and scratches. Regarding the absence of any abnormalities, if the fatigue state of the top plate 21 does not exceed a predetermined state, then the abnormality of the top plate 21 is not considered to be an abnormality of the top plate 21. Regarding presence or absence, it is determined to be "no abnormality". On the other hand, the second acquisition unit 312 determines the fatigue state of the top plate 21. If the condition exceeds the specified state, it is determined that there is an abnormality in the top panel 21. The second acquisition unit 312 acquires the judgment result regarding whether or not there is an abnormality in the top plate 21. The time and / or equipment ID, etc., are obtained as abnormality information. Unknown information is stored in the storage unit 330 for each furniture ID, for example.

[0043] The method by which the second acquisition unit 312 acquires abnormality information is optional. 2 The acquisition unit 312 learns, for example, the fatigue state of the top plate 21, such as cracks and scratches that have occurred on the top plate 21. The machine learning model is then fed data related to video and images captured by the camera, and the top panel 21 The presence or absence of an abnormality may be obtained by outputting the presence or absence of an abnormality. Second acquisition unit 31 2 receives information about the presence or absence of abnormalities from the user of the fixture 20 in a predetermined manner, and based on the received results... You may then obtain information on whether or not there is an anomaly.

[0044] Furthermore, regarding the timing at which the second acquisition unit 312 acquires information on whether or not there is an abnormality in the top plate 21, This is optional. For example, information on whether or not there is an abnormality in the top panel 21 can be obtained daily or at predetermined intervals. However, users of fixture 20 may request confirmation of whether or not there are any abnormalities at predetermined intervals. When sending and receiving confirmation results, you may also obtain information about whether or not there are any abnormalities.

[0045] Furthermore, regarding the presence or absence of abnormalities in the top plate 21, the above is based on the fatigue state of the top plate 21. The question is whether to determine if there is an abnormality in the board 21, but how exactly do you determine if there is an abnormality in the top board 21? This is optional. Furthermore, the criteria for determining whether or not there is an abnormality in the top panel 21 may be changed as appropriate. For example, The settings are adjusted as appropriate depending on the type of furniture (desks, chairs, etc.), the material, weight, size, etc. of the tabletop (21). It is possible.

[0046] The adjustment unit 314 adjusts a predetermined threshold based on the deflection information, the estimation result, and the abnormality information. Adjust the deflection threshold value (980(N)). Figure 8 shows the deflection threshold value (980(N)). This figure shows an example of a process for adjusting the settings.

[0047] The adjustment unit 314 adjusts based on the acquired deflection information and the deflection threshold (980(N)). Determine whether the result matches the result of the abnormality information, and make adjustments as necessary. do.

[0048] For example, if the estimation result and the abnormality information result match, the adjustment unit 314 will... Do not adjust the deflection threshold.

[0049] Furthermore, if the estimation result and the abnormality information result do not match, the adjustment unit 314 will... Adjust the wobble threshold.

[0050] Specifically, the estimation result is "no abnormality," but the abnormality information result is "abnormality present." If present, the top plate 21 of the fixture 20 is included in P1(N) of the acquired deflection information. Therefore, it can be determined that the durability is inferior to the current deflection threshold (980(N)).

[0051] Therefore, in order to more accurately estimate whether or not there is an abnormality in the top plate 21 of the fixture 20, Since it is preferable to set it lower than the deflection threshold at that point in time, the adjustment unit 314 adjusts the deflection threshold. For example, the value of the load P1(N) included in the acquired deflection information is set to 90%. The threshold is adjusted to a predetermined value.

[0052] Furthermore, the estimated result was "abnormal," while the abnormality information result was "no abnormality." In this case, the top plate 21 of the fixture 20 is subjected to the load P1(N) included in the acquired deflection information. Therefore, it can be determined that it has greater durability than the current deflection threshold (980(N)).

[0053] Therefore, in order to more accurately estimate whether or not there is an abnormality in the top plate 21 of the fixture 20, Since it is preferable to set it higher than the deflection threshold at that time, the adjustment unit 314 sets, for example, the deflection threshold Regarding the value, use the value of the load P1(N) included in the acquired deflection information, or set the deflection threshold. Adjust to raise the value to the specified level.

[0054] Regarding the method for adjusting the deflection threshold, for example, how much to increase or decrease the deflection threshold. Therefore, it is optional. Also, the amount of increase or decrease in the deflection threshold, the adjustment method algorithm, etc. may be adjusted as appropriate. You may change these. For example, the type of furniture 20 (desks, chairs, etc.), the material of the tabletop 21, its weight, and size. It can be set as appropriate by factors such as [specific settings].

[0055] Furthermore, the adjustment unit 314 performs adjustment processing, for example, by processing the attribute information of the top plate 21 (material of the top plate 21). Quality, weight, size, etc. may be further referenced and adjusted based on a predetermined algorithm. The predetermined threshold may be adjusted.

[0056] Based on the above, the deflection threshold is determined based on the deflection information, the estimation result, and the anomaly presence / absence information. By adjusting the deflection threshold, the occurrence of abnormalities in the top plate 21 of the fixture 20 is controlled by the adjusted deflection threshold. Therefore, it can be estimated with high accuracy.

[0057] Figure 9 is a diagram illustrating an overview of another example of the adjustment process in this embodiment. In this embodiment, first, the information processing device 30 receives data from the storage unit 330, including the top plate 2 of the furniture 20. Deflection history information 331 regarding the deflection history of 1, and history of whether or not there is an abnormality in the top plate 21. The status history information 332 is obtained, and the deflection history information 331 and the status history information 332 are obtained. Based on a predetermined threshold, the system estimates the occurrence of an abnormality in the top panel 21. In addition, the information processing device 30 The system obtains information regarding the presence or absence of abnormalities in the top panel 21, along with deflection history information 331 and the situation. Based on the historical information 332, the estimation results, and the anomaly information, a predetermined threshold is adjusted.

[0058] The estimation unit 313 receives from the memory unit 330 the history of the deflection of the top plate 21 of the furniture 20. The history information 331 of the deflection history and the history of the results regarding whether or not there is an abnormality in the top plate 21, and the status history information 3 32 is obtained. In addition, the estimation unit 313 determines the situation based on the situation history information 332. Obtain the historical coefficient.

[0059] The deflection history information 331 refers to the past deflection data stored in the memory unit 330 for each fixture ID. Based on accumulated information, the total load applied to the fixture ID, the time elapsed since purchase, etc., are recorded. This is historical information about the deflection data that was recorded.

[0060] Status history information 332 refers to past abnormalities stored in the memory unit 330 for each fixture ID. Based on the accumulation of uninformation, it is estimated that after a certain period of time has elapsed since purchase, an abnormality will occur in the fixture 20. This is historical information about the presence or absence of abnormalities that has been recorded. Situation history information 332 is an example. For example, if the judgment of the status regarding whether or not there is an abnormality in the top plate 21 of the fixture 20 is made, The memory unit 330 stores the history of the situation, including the total load applied to the fixture 20 at that time. ru.

[0061] The status history coefficient is determined based on the status history information 332, for example, the category and type of the fixture 20. For each category, how long after purchase did the fixture 20 malfunction? Therefore, the status regarding the presence or absence of abnormalities in the top panel 21 was statistically processed and converted into a coefficient. The status history coefficient is included in the status history information 332 and stored in the storage unit 330.

[0062] The setting of the status history coefficient is optional, and the setting of the status history coefficient is... Therefore, these may be changed as appropriate. For example, the type of furniture 20 (desks, chairs, etc.), the material of the tabletop 21, It can be set appropriately depending on weight, size, etc. Furthermore, the condition history coefficient is related to the deflection history. Information 331 and status history information 332, etc., may be statistically processed and converted into coefficients, for example, Desks, chairs, etc., are in the same furniture category, but there are 20 other types of furniture with different designs, etc. The situation history information 332, etc., may be statistically processed and converted into a coefficient.

[0063] The estimation unit 313, for example, obtains the fixture ID to be estimated, and based on the obtained fixture ID, The memory unit 330 stores deflection history information 331 and status history information 3 for each furniture ID. The status history coefficient included in 32 is obtained, and based on a predetermined threshold, the occurrence of an abnormality in the top plate 21 is detected. It estimates. The estimation unit 313 receives from the first acquisition unit 311 the top plate 21 of the fixture 20. When obtaining deflection information related to deflection, you may also obtain the fixture ID.

[0064] Figure 10 shows another example of the process for estimating the occurrence of an abnormality in the top plate 21. In this embodiment, The estimation unit 313 uses a predetermined threshold value, which is the total deflection threshold (100,000 (N)). In order to compare with the total deflection threshold (100,000 (N)), the total load P2 (N) is used to measure the situation history. Multiply by the condition history coefficient included in report 332. (Hereafter, the total load P2(N) is multiplied by the condition history information The result obtained by multiplying by the condition history coefficient included in 332 is also called the estimated total load P2(N).

[0065] For example, if the total load P2(N) is 30,000(N) during period T31, Multiplying by the condition history coefficient (1.0), the estimated total load P2 (N) is 30,000 (N). T3 If the total load P2(N) is 70,000(N) during period 2, then the condition history coefficient (1 Multiplying by 0.5), the estimated total load P2(N) is 105,000(N). Period T32 In this case, if the total load P2(N) is 110,000(N), then the condition history coefficient is (2.0). Multiplying by this, the estimated total load P2(N) is 220,000(N).

[0066] Next, during the period T21, the estimated total load P2(N) is equal to the total deflection threshold of 10 Since it is less than 10,000 (N), the estimation unit 313 concludes that there is "no abnormality" regarding the occurrence of an abnormality in the top plate 21. This is an estimate.

[0067] On the other hand, during the period T22, the estimated total load P2(N) is equal to the total deflection threshold of 10 Since the value is over 10,000 (N), the occurrence of an abnormality in the top panel 21 is presumed to be "abnormal."

[0068] How is the initial value of the total deflection threshold (here, "100,000 (N)") set? This is optional. Also, the total deflection threshold can be a fixed value or changed as appropriate. Example For example, depending on the type of furniture 20 (desks, chairs, etc.), the material, weight, size, etc. of the tabletop 21, it should be set appropriately. It can be determined.

[0069] The adjustment unit 314 receives deflection history information 331, status history information 332, estimation results, and abnormalities. Based on the presence or absence information, the predetermined threshold value, the total deflection threshold (100,000 (N)), is adjusted. Figure 11 shows another example of the process for adjusting the total deflection threshold (100,000 (N)). .

[0070] The adjustment unit 314 adjusts based on the estimated total load P2 (N) and the total deflection threshold (100,000 (N)). Then, determine whether the estimated result matches the result of the anomaly information, and if necessary Adjust accordingly.

[0071] For example, if the estimation result and the abnormality information result match, the adjustment unit 314 will... Do not adjust the total deflection threshold.

[0072] Furthermore, if the estimation result and the abnormality information result do not match, the adjustment unit 314 will... Adjust the total deflection threshold.

[0073] Specifically, the estimation result is "no abnormality," but the abnormality information result is "abnormality present." If present, the top plate 21 of the fixture 20, at the estimated total load P2(N), is If the total deflection threshold (100,000 N) is exceeded, it can be determined that the material lacks durability.

[0074] Therefore, in order to more accurately estimate whether or not there is an abnormality in the top plate 21 of the fixture 20, Since it is preferable to set it lower than the total deflection threshold at that time, the adjustment unit 314, for example, acquires Based on the deflection history information 331, 90% of the estimated total load P2(N) is calculated. Adjustments are made to lower the total deflection threshold to a predetermined value, such as by changing it to [specific value].

[0075] Furthermore, if the estimated result is "abnormal" and the acquired abnormality information result is "no abnormality" If present, the top plate 21 of the fixture 20, at the estimated total load P2(N), is It can be judged to have greater durability than the total deflection threshold (100,000 N).

[0076] Therefore, in order to more accurately estimate whether or not there is an abnormality in the top plate 21 of the fixture 20, Since it is preferable to set it higher than the total deflection threshold at that time, the adjustment unit 314, for example, acquires Based on the deflection history information 331, the estimated total load P2(N) is calculated to the value of, etc. The total deflection threshold is adjusted to a predetermined value.

[0077] Regarding the adjustment of the total deflection threshold, the amount to which the total deflection threshold is increased or decreased is arbitrary. The amount and method of increasing or decreasing the total deflection threshold may be changed as appropriate. For example, the type of fixture 20 The type of table (desk, chair, etc.), material, weight, size, etc. can be set appropriately. .

[0078] In addition, the adjustment unit 314 performs an adjustment process that includes, in addition to the above, the attribute information of the top plate 21 (top plate 21 The material, weight, size, etc. may be further adjusted by referring to a predetermined algorithm. The predetermined threshold may be adjusted.

[0079] Based on the above, the deflection history information 331, the status history information 332, the estimated result, and the presence or absence of abnormalities are as follows: Based on the report, the total deflection threshold is adjusted to detect abnormalities in the top plate 21 of the fixture 20. The state can be estimated more accurately using an adjusted total deflection threshold.

[0080] <About the screen display> Next, the information processing device 30 is used to process the images of the information processing terminal 40, etc., based on whether or not there is an abnormality. The method of displaying information on the surface will be explained in detail. For example, information that an abnormality has been detected in fixture 20. The processing unit 30 displays an abnormality of the fixture 20 on the information processing terminal 40, and the information processing terminal 40 The received maintenance service request information can be displayed on the information processing terminal 50. Cut.

[0081] The generating unit 315 generates the conditions relating to the deflection of each of the top plates 21 of the multiple fixtures 20. Output information is generated to indicate whether or not there is an abnormality in the top panel 21 for each of the multiple fixtures 20. Figure 12 shows the output information for displaying whether or not there is an abnormality for each of the multiple fixtures 20. This is an example of the screen that displays whether or not an abnormality is present. The generation unit 315 generates output information This may be stored in the memory unit 330.

[0082] As shown in Figure 12, the generation unit 315 can display the presence or absence of abnormalities in a list format. It generates output information. In the example display screen G1 in Figure 12, the title G101 and description are displayed. Text G102 and list display area G103 are displayed. Title G101, description G The display contents of 102 and list display area G103 are examples of output information. The output information generated by 315 is not limited to display in list format; for example, it can also be displayed in map format. It can also generate output information that can be displayed.

[0083] The title G101 is an element that shows an overview of the display screen. In the example display screen in Figure 12, it says: The screen displays "Abnormality Display Screen," and explanatory text G102 describes the fixture 20 that has detected an abnormality. This is a statement clarifying the following. In the example display screen in Figure 12, the abnormality was detected in fixtures ID 0002 and 00 Regarding item 05, the message reads: "An anomaly has been detected for fixtures IDs 0002 and 0005." It is shown.

[0084] For detecting abnormalities in each piece of furniture 20, for example, the estimation unit 313 detects abnormalities in each piece of furniture 20. The abnormality of the top panel 21 is detected by estimating it. Specifically, the estimation unit 313, Regarding the fixture 20 that was presumed to have an abnormality, an abnormality was detected and it was presumed to have no abnormality. Regarding the fixture 20, it is acceptable not to detect any abnormalities.

[0085] The list display area G103 shows the state of the deflection of each of the top plates 21 of the multiple fixtures 20. The system displays a list indicating whether or not there are any abnormalities in the tabletop 21 and related information for each piece of furniture 20. This is the area. In the example display screen in Figure 12, the list display area G103 shows whether or not there is an abnormality. The icon, fixture ID, purchase date, warranty period, and service inquiry link are displayed. Yes. Furthermore, in the list display area G103, what items will be displayed as related information? Doing so is optional and may be changed as needed. For example, regarding the 20 types of furniture (desks, chairs, etc.) Therefore, it can be set as appropriate.

[0086] Items such as purchase date and warranty period, which are displayed in the list display area G103, are fixtures. The information is displayed based on the ID. The icons indicating whether or not there is an anomaly are estimated. Based on the estimation results regarding the presence or absence of an abnormality estimated by section 313, the presence or absence of an abnormality is determined. The icons are displayed separately. In the example screen shown in Figure 12, the fixture 20 is estimated to have an "abnormality". Regarding this, it was displayed as "Black fixture 20" and fixture 20 was estimated to be "no abnormality". It will be displayed as "White fixture 20".

[0087] For service inquiries (click here), please refer to the maintenance service for fixture 20. Then, a link to the screen where you can submit an inquiry will be displayed. The screen for connecting will be explained later.

[0088] Based on the above, the user can see whether or not there is an abnormality displayed in the list display area G103. Icons, etc., describe the situation regarding the deflection of each of the top plates 21 of multiple fixtures 20. The presence or absence of abnormalities in the top panel 21 can be intuitively recognized, and the information is linked to the fixture ID. The warranty period and purchase date are displayed, and relevant information for each piece of fixture 20 can be checked while making an inquiry. You can click a link to proceed to a screen where the request is accepted.

[0089] The generating unit 315 generates the conditions relating to the deflection of each of the top plates 21 of the multiple fixtures 20. Based on whether or not there is an abnormality in the top panel 21, the multiple fixtures 20 will be equipped with the abnormal top panel 21. One or more fixtures 20, and receiving a prescribed service for one or more fixtures 20. Generate output information to output in association with information for recommending to the user. This is also fine. The recommendation display screen G2, shown in Figure 13, is an example of a display screen, for example, maintenance. This is an example of a screen displayed to recommend a service to a user. Oh, in the example display screen in Figure 13, the recommendation display screen G2 is above the abnormality / absence display screen G1. Although they are displayed overlapping, this is not the only way in which the recommendation display screen G2 is displayed. It is acceptable for only the recommendation display screen G2 to be displayed on the screen.

[0090] As shown in Figure 13, the generation unit 315 informs the user that they will receive maintenance services. Generates output information that can display information for making recommendations. Title: G104 This element shows an overview of the recommendation display screen. In the example display screen in Figure 13, it says "Recommend The display screen is labeled "Recommendation screen," and recommendation text G105 is an overview of recommendations to the user. This is an element that indicates [something]. In the example display screen in Figure 13, for example, the fixture ID in which an anomaly was detected is shown. It is determined that the item is eligible for recommendation, and the item ID of the item 20, the name of the service to be recommended, and The following is a description of how to request the service. Note that recommendation text G105, etc. The displayed content is an example of output information.

[0091] For example, the generation unit 315 determines that the recommended furniture ID is "abnormal" by the estimation unit 313. Based on the fixture 20 which is estimated to be "present", output information is generated. The generation unit 315 generates the recommendation The G105 command may be modified based on the recommended furniture ID. For example, The maintenance unit 315, based on the warranty period information linked to the recommended fixture ID, Output information regarding the nonce service name may be generated.

[0092] Specifically, the generation unit 315 determines that the recommended fixture ID is covered under the warranty period. In other words, if repair is cheaper than replacement within the warranty period, then maintenance service Generate output information for a description requesting maintenance services, using "repair" as the name. It is also permissible to do so if it is determined that the generating unit 315 is outside the warranty period. If replacement is cheaper, request the maintenance service and specify "replacement" as the service name. Output information regarding the explanatory text for this purpose may be generated.

[0093] Therefore, by displaying the information for recommendation on the information processing terminal 40, The system will promptly recommend, for example, measures to resolve the abnormality in the malfunctioning fixture 20. Users can take actions such as requesting maintenance services. Before accepting a request for maintenance services, please note that the repair of the top panel 21 and other maintenance services may be required. It can be proposed.

[0094] The system accepts user input to select a specific piece of furniture 20 from among multiple pieces of furniture 20. The system includes a reception unit 316, and the generation unit 315 generates a specific fixture selected by user input. Generate output information to output a screen for providing a predetermined service to 20. That's good too.

[0095] The reception unit 316 receives user input. For example, if the user is displayed If you want to select a specific piece of furniture 20 from among multiple pieces of furniture 20 that has been detected to have an abnormality, Click the inquiry link associated with the specific fixture 20 on the list displayed on the screen. By doing so, the reception unit 316 receives user input for selecting a specific fixture 20. Then, accept it. Note that there may be one or more of the specific fixtures 20. Also, accept The attachment unit 316 may store the received information in the storage unit 330.

[0096] The generation unit 315 generates maintenance data for a specific piece of furniture 20 selected by user input. Output information is generated to output a screen for providing nonce. For example, generation unit 31 5 refers to the information that a company providing maintenance services needs to carry out, for example, replacements. Regarding the information, generate output information to display a screen that prompts the user to input that information. Then, the reception unit 316, from the screen for providing maintenance services, receives the user's information. Accepting input.

[0097] Figure 14 shows one of the service provision screens displayed when providing maintenance services. This is an example. For instance, in the example screen G3 in Figure 14, the title G106 and the information input area are displayed. Area G107 and the transmit button G108 are displayed.

[0098] The title G106 is an element that shows an overview of the display screen. In the example display screen in Figure 14, it says: The screen displays "Service Provision Screen".

[0099] The information input area G107 provides users with the information necessary to provide maintenance services. This is the area displayed for input. In the example display screen in Figure 14, the information input area is G107. Your name, email address, requested service, equipment ID, and inquiry details will be displayed. In addition, in the information input area G107, the information requested from the user is... Displaying items like these is optional and can be changed as needed.

[0100] The requested services include replacement, repair, and / or recycling of fixtures 20. It may be possible to input information by selecting the maintenance service content.

If the presence / absence display screen G1 was displayed, the information can be obtained from the abnormal presence / absence display screen G1. It may be entered dynamically.

[0101] In the example display screen in Figure 14, a transmit button is used to send the entered information to the information processing device 30. G108 is displayed. The information processing device 30 receives the predetermined information entered by the user. Upon receiving an application from Section 316, the company that will perform the replacement will be required to provide maintenance services. The information processing device 30 outputs the requested information regarding maintenance. The results of the service assignments may be received from these companies and forwarded to the users.

[0102] Therefore, by displaying the service provision screen on the information processing terminal 40, the user can Select a fixture 20 that is functioning normally, and for example, replace or repair part or all of the fixture 20 that has detected an abnormality. The system allows users to request maintenance services such as repairs and other related tasks, and notifies users of any abnormalities. It can support the provision of services to the detected fixture 20.

[0103] The location information acquisition unit 317 acquires location information regarding the position of each of the multiple fixtures 20. For example, the sensor 210 can be used to obtain location information of the furniture 20 within the office.

[0104] The generation unit 315 generates positional information and information relating to the deflection of each of the top plates 21 of the multiple fixtures 20. Based on the presence or absence of abnormalities in the top panel 21, output on the map Output information is generated. The generation unit 315 includes a tabletop 21 with an abnormality among the multiple fixtures 20. One or more objects indicating a fixture 20, and a top plate 2 of the fixtures 20 that is free of defects. One or more objects representing a fixture 20 equipped with 1 are shown on the map in different ways. Generate output information for output.

[0105] Figure 15 shows the output information for displaying whether or not there is an abnormality for each of the multiple fixtures 20. This is an example of the map display screen G4. The example display screen G4 shows the title G108. Description G109 and map display area G110, object G111 and message G 112 is displayed. Note that the displayed content such as the title G108 is just an example of the output information. ru.

[0106] The title G108 is an element that shows an overview of the display screen. In the example display screen in Figure 15, it says: The screen displays "Map Display Screen," and explanatory text G109 describes the fixture 20 that detected the anomaly. This is the statement. In the example display screen in Figure 15, an abnormality was detected in fixture ID 0002. The message displayed is, "An anomaly has been detected regarding fixture ID 0002."

[0107] The map display area G110 displays location information and the height of each of the top panels 21 of the multiple fixtures 20. The area displays on the map whether or not there is an abnormality in the top panel 21 and related information as a condition of the situation. It is a region.

[0108] For example, the generation unit 315 acquires the office map information stored in the storage unit 330, The location information acquisition unit 317 acquires the location of each of the multiple fixtures 20.
