  According to this configuration, the log information includes the sensor value. The first operation mode information includes a plurality of first operation mode information generated at predetermined intervals. A first point in time when an abnormality has occurred in the sensor value in the past is detected. In the generation of the second operation mode information, the first operation mode information generated before the first time point is extracted from among the plurality of first operation mode information, and extracted based on the correction function. Second operation mode information is generated from the first operation mode information.

  Therefore, the second operation is performed based on the first operation mode information generated before the first time point at which it is estimated that the sensor value of the first device has deteriorated and the first device has deteriorated in the past. Since the mode information is generated, the second operation is generated from the first operation mode information generated before the first device degrades in consideration of the change of the first operation mode information due to the degradation of the first device. Mode information can be generated, and the second operation mode information can be used to control the second device to the user's preference.

  Further, in the device control method described above, the log information includes a sensor value, and further, detects a first point in time when an abnormality occurs in a sensor value of the first device in the past, and the second operation mode Information generation is performed by generating the first operation mode information based on the log information prior to the first time point, and based on the generated first operation mode information based on the correction function.

  In the device control method described above, generation of the second operation mode information may be performed by the first of the plurality of first operation mode information when it is determined that the second time point does not exist. The first operation mode information generated before the time point may be extracted, and the second operation mode information may be generated from the extracted first operation mode information based on the correction function.

  According to this configuration, when it is determined in the generation of the second operation mode information that the second point in time does not exist, the second operation mode information is generated before the first point in time among the plurality of pieces of first operation mode information. The first operation mode information is extracted, and the second operation mode information is generated from the extracted first operation mode information based on the correction function.

The second operation mode information can be used to further control the second device according to the preference of the user.

  In the device control method described above, generation of the second operation mode information may be performed based on the log information prior to the first point of time, when it is determined that the second point of time does not exist. One operation mode information may be generated, and the second operation mode information may be generated from the generated first operation mode information based on the correction function.

  According to this configuration, when it is determined in the generation of the second operation mode information that the second time point does not exist, the first operation mode information is generated based on the log information before the first time point. Second operation mode information is generated from the generated first operation mode information based on the correction function.

  Therefore, when the first device degrades without a sign, the second operation mode information is generated from the first operation mode information generated based on the log information prior to the first time point at which the first device degraded. The second device can be further controlled to the user's preference using the second operation mode information.

  In the device control method described above, the log information includes a sensor value, the first operation mode information includes a plurality of first operation mode information generated for each predetermined period, and the past.

The first operation mode information includes a plurality of first operation mode information generated at predetermined intervals. A first point in time when an abnormality has occurred in the sensor value in the past is detected. Among the plurality of first operation mode information, whether or not there is a second time point at which the first operation mode information generated before the first time point has changed from the immediately preceding first operation mode information Is judged. If it is determined that the second point in time exists, it is determined whether or not the use state of the first device has changed at the second point in time. In the generation of the second operation mode information, if it is determined that the usage state of the first device has not changed at the second point in time, the plurality of pieces of first operation mode information precedes the second point in time The first operation mode information generated in step (d) is extracted, and second operation mode information is generated from the extracted first operation mode information based on the correction function.

  Therefore, if the factor at which the first operation mode information has changed from the immediately preceding first operation mode information at the second point in time is a change in the use state of the first device, the second point in time is the second point It can be determined that it is not at the point when the sign of deterioration of the device 1 appears. Also, if the factor at which the first operation mode information has changed from the immediately preceding first operation mode information at the second point in time is not the change in the usage status of the first device, the second point in time is It can be judged that it is the time when the sign of the deterioration of the device 1 appeared. Therefore, if it is determined that the use state of the first device has not changed at the second time point, the first operation generated before the second time point at which the first device shows signs of deterioration. Since the second operation mode information is generated from the mode information, the second device can be controlled to the user's preference using the second operation mode information.

The first operation mode information generated before the first time point is extracted from the operation mode information, and the second operation is extracted from the extracted first operation mode information based on the correction function. Mode information may be generated.

  According to this configuration, when it is determined in the generation of the second operation mode information that there has been a change in the usage status of the first device at the second time point, the first of the plurality of first operation mode information is selected. First operation mode information generated before time 1 is extracted, and second operation mode information is generated from the extracted first operation mode information based on the correction function.

  Therefore, if it is determined that the usage state of the first device has changed at the second time point, the first operation mode information generated before the first time point at which the first device has deteriorated is determined from the first operation mode information Since two operation mode information is generated, the second device can be controlled in accordance with the user's preference using the second operation mode information.

  In the device control method described above, generation of the second operation mode information is performed from the first point of time when it is determined that the use state of the first device has changed at the second point of time. The first operation mode information may be generated based on the previous log information, and the second operation mode information may be generated from the generated first operation mode information based on the correction function.

If the similarity between the mode information and the first operation mode information immediately before the mode information is lower than a predetermined value, it may be determined that the second time point is present.

  According to this configuration, in the determination of whether or not the second time point exists, the first operation mode information generated before the first time point and the first immediately before the first operation mode information are generated. If the degree of similarity with the operation mode information is lower than a predetermined value, it is determined that a second time point exists.

  Therefore, it is possible to easily detect the second time point at which the first operation mode information generated before the first time point has changed from the immediately preceding first operation mode information.

The registration information includes information on the user such as the user ID, the device ID and the installation location, and information on the first device 200.

  Also, when the user starts using the first device 200, the communication unit 101 receives, from the first device 200, a state change notification or a periodic state notification of the first device 200. Also, the communication unit 101 receives control content from the portable terminal 400, and transmits the received control content to the first device 200. The control content includes, for example, setting information such as ON operation, OFF operation, temperature, air volume, and wind direction.

  Furthermore, the communication unit 101 transmits the automatic mode function generated in the server 100 to the first device 200.

Then, the automatic mode function generation unit 102 adds the generated automatic mode function to the table indicating the device ID of the first device 200 in the automatic mode function DB 106. The automatic mode function generation unit 102 outputs the generated automatic mode function to the communication unit 101, and the communication unit 101 transmits the automatic mode function to the first device 200. Details of the tables in the automatic mode function DB 106 will be described in the description of the automatic mode function DB 106.

  Further, when the automatic mode function generation unit 102 transplants the automatic mode function of the first device 200 to the second device 300, the automatic mode function generation unit 102 is input from the change point detection unit 103 from the registration time of the first device 200. The operation history of the first device 200 up to the time when the first device 200 is estimated to be degraded is extracted from the device log DB 107, and the automatic mode function of the second device 300 is generated using the extracted operation history. .

  FIG. 3 is a diagram for describing an example of generating an automatic mode function in the present embodiment. Here, a case will be described in which the user newly purchases the first device 200 on July 8, 2017, and buys the second device 300 in July 2023. Also, for simplicity, the function representing the automatic mode is described using an example of becoming a regression curve, but the function representing the automatic mode is not limited to the regression curve, but may be a higher dimensional function . The high-dimensional representation of the automatic mode function results in more parameters representing the function and allows finer customization and control. In the present embodiment, the automatic mode is represented by a function, but the present disclosure is not particularly limited thereto.

  When the first device 200 is newly purchased, a function represented by the following equation (1) is set as an initial function.

f ₀ (x ₁ ,..., x _n ) (1)

  The initial function is generally designed to make people feel comfortable. Then, based on the status change notification or the periodic status notification received from the first device 200, the automatic mode function generation unit 102 updates the initial function stored in advance in the first device 200 according to the user's preference. By doing this, the function shown in the following equation (2) is updated.

f _i (x ₁ ,..., x _n ) (2)

f _i-1 (x ₁ ,..., x _n ) (3)

  The automatic mode function generation unit 102 finely adjusts the initial function based on the operation history and sensor information of each year and each season. The automatic mode function is updated, for example, once a week. If there is no history of user operations during a week, the current automatic mode function is followed.

  FIG. 4 is a diagram showing an example of the automatic mode function generated by the automatic mode function generator in the present embodiment. The function shown in FIG. 4 is represented by a regression surface. When plotting the time-series changes of the room temperature, the outside temperature, and the operation elapsed time, when the season is winter, both the outside temperature and the room temperature are low immediately after the power of the air conditioner is turned on, As time goes on, the room temperature rises. When the season is summer, both the outside air temperature and the room temperature are high immediately after the air conditioner is turned on, and the room temperature decreases with the passage of time. Furthermore, together with the regression surface, the difference from the set temperature may be expressed by the size of a point. In the above description, the actual temperature change is plotted, but the axis may be determined by another item such as the change in the actual set temperature, or the variable may be a color or thickness as a function to be visualized. It may be expressed by a high dimensional figure represented by.

  When porting the automatic mode function of the first device 200 to the second device 300, the change point detection unit 103 estimates that the first device 200 has deteriorated and the deterioration of the first device 200. To detect when the sign of When the change point detection unit 103 detects a time point estimated to be degraded, it extracts the latest automatic mode function before the time point estimated to be degraded from the automatic mode function DB 106 and outputs it to the performance difference correction unit 104. . At this time, the change point detection unit 103 may output, to the automatic mode function generation unit 102, information indicating a time point at which it is estimated that the change has occurred.

  The performance difference correction unit 104 generates a correction function for correcting the performance difference between the devices in all the combinations of the plurality of devices stored in the product information DB 109. The performance difference correction unit 104 acquires a plurality of pieces of performance information indicating the performance of each of a plurality of devices including the first device 200 and the second device 300. The performance difference correction unit 104 generates a plurality of correction functions based on the difference in performance information of each combination of a plurality of devices.

  The performance difference correction unit 104 acquires first performance information indicating the performance of the first device 200 and second performance information indicating the performance of the second device 300. The performance difference correction unit 104 generates a correction function based on the difference between the first performance information and the second performance information. The performance difference correction unit 104 extracts a correction function corresponding to the combination of the first device 200 and the second device 300 from among the plurality of correction functions.

  FIG. 5 is a diagram for describing generation of a correction function for correcting a difference in performance of air volume when the first device and the second device are air conditioners. The first device 200 is a 2017 model A series air conditioner, and the second device 300 is a 2023 model A series air conditioner. With the performance of the first device 200 and the performance of the second device 300, the volume of the wind corresponding to the “strong wind” of the 2017 model is “slightly strong wind of the 2023 model” by improving the performance such as increasing the circulation efficiency of the wind. The design has been changed so as to be the same as the air volume corresponding to “(air volume numerical level 5). Further, due to the similar performance improvement, the variation of the air volume is increased (air volume numerical levels 1 to 4), and a weaker air volume setting and a finer air volume setting are possible.

  FIG. 6 is a diagram for explaining the difference in control due to the difference between the performance of the first device and the performance of the second device. In FIG. 6, the time change of the outside air temperature is the same in the case of controlling the first device 200 and the case of controlling the second device 300, and the time change of the set temperature is also the same. In this case, the first device 200 of the 2017 model A series controls with a “strong” air volume, while the second device 300 of the 2023 model A series controls with a “slightly strong” air volume. Be done. The performance difference correction unit 104 generates a correction function so as to absorb the difference between the performance of the second device 300 and the performance of the first device 200.

  The following is a correction function for correcting the difference between the performance of the first model 200 for 14 tatami in the 2017 model A series and the performance of the second instrument 300 for 14 tatami in the 2023 model A series. An example of generation will be described.

  The function of each set air volume of the first device 200 for 14 tatami of the 2017 model A series is expressed by the following equation (4), and each of the second device 300 for 14 tatami of the 2023 model A series The function of the set air volume is expressed by the following equation (5).

  At this time, an equation for converting the equation (4) into the equation (5) is expressed as the following equation (6).

g _{23 A 14 — i} (x ₁ , x ₂ ,..., x _n ) = α _{17 A 23 A} (x ₁ , x ₂ ,..., x _n ) · g _{17 A 14 — j} (x ₁ , x ₂ ,..., x _n ) ... (6)

  Then, the correction function is expressed by the following equation (7).

α _ij (x ₁ , x ₂ ,..., x _n ) (7)

  After generating the correction function, the performance difference correction unit 104 stores the generated correction function in the correction function storage unit 105.

  Further, when the automatic mode function generation unit 102 transplants the automatic mode function of the first device 200 to the second device 300, the difference between the performance of the first device 200 and the performance of the second device 300 is corrected. A correction function to be used is extracted from the correction function storage unit 105, and the automatic mode function of the first device 200 is corrected based on the extracted correction function.

  The automatic mode function generation unit 102 operates the first device 200 generated based on the log information of the first device 200 based on the correction function generated by the performance difference correction unit 104 with the first setting. The second operation mode information for causing the second device 300 to operate with the second setting corresponding to the first setting is generated from the first operation mode information. The first operation mode information is a first automatic mode function, and the second operation mode information is a second automatic mode function. The communication unit 101 transmits the second automatic mode function (second operation mode information) generated by the automatic mode function generation unit 102 to the second device 300.

  Further, the change point detection unit 103 detects a first point in time when an abnormality has occurred in the sensor value measured by the first device 200 in the past. The automatic mode function generation unit 102 extracts a first automatic mode function generated before the first time point out of the plurality of first automatic mode functions, and extracts the first extracted automatic mode function based on the correction function. Generate a second auto mode function from the auto mode function. Note that the automatic mode function generation unit 102 generates a first automatic mode function based on log information of the first device 200 before the first time point, and generates a first automatic mode generated based on the correction function. A second automatic mode function may be generated from the function.

  Furthermore, the change point detection unit 103 may be configured such that, among the plurality of first automatic mode functions, the first automatic mode function generated before the first time point is changed from the immediately preceding first automatic mode function. It may be determined whether two time points exist. Then, when it is determined that the second time point is present, the automatic mode function generation unit 102 generates the first automatic mode function generated before the second time point among the plurality of first automatic mode functions. And may generate a second automatic mode function from the extracted first automatic mode function based on the correction function.

  Further, when it is determined that the second time point does not exist, the automatic mode function generation unit 102 generates a first automatic mode generated before the first time point among the plurality of first automatic mode functions. The function may be extracted, and a second automatic mode function may be generated from the extracted first automatic mode function based on the correction function. Further, when it is determined that the second time point does not exist, the automatic mode function generation unit 102 generates a first automatic mode function based on log information of the first device 200 before the first time point. A second auto mode function may be generated from the generated first auto mode function based on the correction function.

  Furthermore, when it is determined that the second time point is present, the change point detection unit 103 may determine whether the use state of the first device 200 has changed at the second time point. If the automatic mode function generation unit 102 determines that the use state of the first device 200 has not changed at the second time point, the automatic mode function generation unit 102 selects the plurality of first automatic mode functions before the second time point. The generated first automatic mode function may be extracted, and a second automatic mode function may be generated from the extracted first automatic mode function based on the correction function.

  In addition, when it is determined that the use state of the first device 200 has changed at the second time point, the automatic mode function generation unit 102 selects one of the plurality of first automatic mode functions than the first time point. A first auto mode function generated previously may be extracted, and a second auto mode function may be generated from the extracted first auto mode function based on the correction function. In addition, when it is determined that the use state of the first device 200 has changed at the second time point, the automatic mode function generation unit 102 adds to the log information of the first device 200 before the first time point. A first auto mode function may be generated based on the first auto mode function, and a second auto mode function may be generated from the generated first auto mode function based on the correction function.

  The change point detection unit 103 determines that the similarity between the first automatic mode function generated before the first time point and the first automatic mode function immediately before the first automatic mode function is lower than a predetermined value. If so, it is determined that a second time point exists.

  The correction function will be described in detail in the description of the correction function storage unit 105.

  The correction function storage unit 105 stores the correction function generated by the performance difference correction unit 104. Further, when the automatic mode function of the first device 200 is ported to the second device 300, the performance difference correction unit 104 refers to the correction function storage unit 105 and extracts the correction function.

  FIG. 7 is a diagram showing an example of a table stored in the correction function storage unit in the present embodiment. The table stored in the correction function storage unit 105 is a correspondence table in which a plurality of devices and a plurality of devices are associated, and the correction function generated by the performance difference correction unit 104 is represented by the following equation (8) expressed.

α _ij (8)

  The automatic mode function DB 106 stores an automatic mode function generated by each device in the past along with the initial automatic mode function. The automatic mode function DB 106 stores first operation mode information for operating the first device 200 with the first setting. The first operation mode information is a first automatic mode function. The first automatic mode function is generated based on the log information of the first device 200.

The outside air temperature, the room temperature, and the humidity are sensor values measured by the sensor 205 of the first device 200.

  For example, when the operation of the air conditioner is started in the automatic mode at 18:00:15 on July 8, 2017, the air conditioner is first operated in the automatic mode. Then, the user changes the wind direction downward at 18:30:00 and changes the air volume weakly. As a result, the time is 18:30:00, the user operation flag is "1", and the line in which the contents of the wind direction and the air volume have changed is added to the device log DB 107.

The communication unit 401 of the portable terminal 400 transmits, to the server 100, response information indicating whether or not to port the automatic mode function of another device to the second device 300. The communication unit 101 of the server 100 receives the response information transmitted by the mobile terminal 400.

  The automatic mode function generation unit 102 of the server 100 determines whether to port the automatic mode function of another device to the second device 300 based on the response result of the automatic mode function porting confirmation process (step S3). . Here, when it is determined that the automatic mode function of another device is not to be ported (NO in step S3), the automatic mode function generation unit 102 performs an automatic mode function generation process (step S4). Then, the process returns to step S1, and the automatic mode function generation process is repeated as long as the same device is used.

  On the other hand, when it is determined that the automatic mode function of another device is to be ported (YES in step S3), the automatic mode function generator 102 performs an automatic mode function porting process (step S5). The automatic mode function porting process includes a porting source device selection process, a change point detection process, and an automatic mode setting process.

  The automatic mode function generation process and the automatic mode function porting process will be described below with reference to the drawings.

  FIG. 18 is a first flow chart for explaining the automatic mode function generation processing in the device control system, and FIG. 19 is a second flow chart for explaining the automatic mode function generation processing in the device control system. In the following, an automatic mode function generation process for generating an automatic mode function used in the first device 200 will be described.

  First, the operation control unit 202 of the first device 200 determines whether or not there has been a user operation by the first operating device 500 or the portable terminal 400 (step S11). Note that the user operation indicates the ON operation of the first device 200, the OFF operation of the first device 200, or the change operation of the setting value of the first device 200. Here, when it is determined that a user operation has been made (YES in step S11), operation control unit 202 generates a state change notification including log information of first device 200 that has been changed by the user operation (step S12). .

  On the other hand, when it is determined that there is no user operation (NO in step S11), operation control unit 202 determines whether or not a predetermined time has elapsed since the generation of the previous periodic state notification (step S13). The predetermined time is, for example, 5 minutes. Here, when it is determined that the predetermined time has elapsed since the generation of the previous periodic status notification (YES in step S13), the periodic status notification including the log information of the current first device 200 is generated (step S14). On the other hand, when it is determined that the predetermined time has not elapsed since the last generation of the periodic state notification (NO in step S13), the process returns to step S11, and operation control unit 202 determines whether or not the user operation has been performed again. Do.

  Next, the communication unit 201 transmits the state change notification or the periodic state notification generated by the operation control unit 202 to the server 100 (step S15).

  Next, the communication unit 101 of the server 100 receives the status change notification or the periodic status notification transmitted by the first device 200 (step S16).

  Next, the communication unit 101 stores the log information included in the status change notification or the periodic status notification in the device log DB 107 (step S17).

  Next, the automatic mode function generation unit 102 determines whether a predetermined period has elapsed since the previous generation of the automatic mode function (step S18). The predetermined period is, for example, one week. Here, when it is determined that the predetermined period has not elapsed since the previous generation of the automatic mode function (NO in step S18), the automatic mode function generation unit 102 continues the predetermined period since the previous generation of the automatic mode function. Determine if it is or not.

  In the present embodiment, when it is determined that the predetermined period has not elapsed since the previous generation of the automatic mode function, the process of step S18 is repeated until the predetermined period elapses, but the present disclosure is particularly limited thereto. Alternatively, if it is determined that the predetermined period has not elapsed since the previous generation of the automatic mode function, the automatic mode function generation process may be terminated.

  On the other hand, if it is determined that a predetermined period has elapsed since the previous generation of the automatic mode function (YES in step S18), automatic mode function generation unit 102 determines whether device log DB 107 has a setting change history by user operation. It judges (step S19). The determination process of step S19 is performed by determining whether there is log information whose user operation flag in the device log DB 107 is "1". Here, when it is determined that there is no setting change history by the user operation in the device log DB 107 (NO in step S19), the automatic mode function generation unit 102 extracts the automatic mode function generated immediately before from the automatic mode function DB 106. (Step S20). When the automatic mode function generated immediately before is extracted, the automatic mode function generation unit 102 may only update the date of the automatic mode function DB 106, or the extracted date is associated with the extracted automatic mode function. It may be stored in the automatic mode function DB 106.

  On the other hand, when it is determined that the device log DB 107 has a setting change history by user operation (YES in step S19), the automatic mode function generation unit 102 extracts the automatic mode function generated immediately before from the automatic mode function DB 106. At the same time, log information for a predetermined period is extracted from the device log DB 107, and a new automatic mode function is generated based on the extracted automatic mode function and log information (step S21).

  Next, the automatic mode function generation unit 102 stores the generated automatic mode function in the automatic mode function DB 106 (step S22).

  Next, the communication unit 101 transmits the automatic mode function extracted or generated by the automatic mode function generation unit 102 to the first device 200 (step S23).

  Next, the communication unit 201 of the first device 200 receives the automatic mode function transmitted by the server 100 (step S24).

  Next, the communication unit 201 stores the received automatic mode function in the automatic mode function storage unit 203 (step S25). At this time, if the automatic mode function is already stored in the automatic mode function storage unit 203, the received automatic mode function is overwritten on the stored automatic mode function.

  When a new automatic mode function is generated in the server 100 and the automatic mode function of the automatic mode function DB 106 is updated, the user may be notified that the automatic mode function has been updated.

  FIG. 20 is a diagram showing an example of a notification screen for notifying the user that the automatic mode function has been updated.

  The communication unit 101 of the server 100 transmits, to the portable terminal 400, notification information for notifying that the automatic mode function of the first device 200 has been updated. The communication unit 401 of the portable terminal 400 receives the notification information transmitted by the server 100. When the notification information is received, the input / output unit 403 displays a notification screen for notifying that the automatic mode function of the first device 200 has been updated.

  The input / output unit 403 of the portable terminal 400 displays a notification screen shown in FIG. The notification screen shown in FIG. 20 notifies that the automatic mode function of the first device 200 has been updated.

  Also, when a new automatic mode function is generated in the server 100, the user may be asked whether the first device 200 automatic mode function may be updated to a new automatic mode function.

  FIG. 21 is a diagram showing an example of a confirmation screen for confirming whether or not the automatic mode function of the first device is to be updated.

  The communication unit 101 of the server 100 transmits, to the portable terminal 400, a confirmation request for confirming whether or not the automatic mode function of the first device 200 is to be updated. The communication unit 401 of the portable terminal 400 receives the confirmation request transmitted by the server 100. When the confirmation request is received, the input / output unit 403 displays a confirmation screen for confirming whether the automatic mode function of the first device 200 is to be updated.

  The input / output unit 403 of the portable terminal 400 displays a confirmation screen shown in FIG. In the confirmation screen, user input as to whether or not the automatic mode function stored in the automatic mode function DB 106 is updated to a new automatic mode function is accepted. The user selects whether to update the automatic mode function of the first device 200 or not. The communication unit 401 of the portable terminal 400 transmits, to the server 100, response information indicating whether to update the automatic mode function of the first device 200. The communication unit 101 of the server 100 receives the response information transmitted by the mobile terminal 400. When the response information indicating that the automatic mode function of the first device 200 is updated is received, the automatic mode function generation unit 102 stores the new automatic mode function in the automatic mode function DB 106. On the other hand, when the response information indicating that the automatic mode function of the first device 200 is not updated is received, the automatic mode function generation unit 102 discards the new automatic mode function, and the automatic mode function generated immediately before is discarded. It extracts from automatic mode function DB106, and it transfers to the process of step S23.

  Subsequently, the automatic mode function porting process of the device control system 10 will be described.

  FIG. 22 is a first flow chart for explaining the automatic mode function porting process in the device control system, and FIG. 23 is a second flow chart for explaining the automatic mode function porting process in the device control system.

  First, the control unit 1 of the server 100 performs a porting source device selecting process for selecting a device to be a porting source of the automatic mode function from among a plurality of devices owned by the user (step S31). In the porting source device selection process, the portable terminal 400 receives an input from the user of the porting source of the automatic mode function, and at this time, the portable terminal 400 is an porting source of the automatic mode function selected by the user. Device ID is transmitted to the server 100.

  FIG. 24 is a diagram showing an example of a selection screen for receiving, by the user, the selection of a device to which the automatic mode function is to be transplanted. The input / output unit 403 of the portable terminal 400 displays a list of devices possessed by the user on the selection screen of the automatic mode function. The user selects a device to which the automatic mode function is to be transplanted, and presses a button ("Next" in FIG. 24) for transmitting the device ID of the selected device to the server 100. The list of displayed devices includes, for example, device IDs and installation locations.

  In addition, after the device which is the porting source of the automatic mode function is selected by the user, it may be confirmed whether the automatic mode function of the selected device may be reflected.

  FIG. 25 is a diagram showing an example of a confirmation screen for confirming whether the automatic mode function of the selected device may be reflected. As shown in FIG. 25, after the device to which the automatic mode function is to be transplanted is selected by the user, the input / output unit 403 of the portable terminal 400 may transplant (reflect) the automatic mode function of the selected device You may display the confirmation screen for confirming.

  In the confirmation screen, when porting the automatic mode function, the user presses a button (“Yes” in FIG. 25) for transmitting the device ID of the selected device to the server 100. On the other hand, in the confirmation screen, when the automatic mode function is not ported, the user displays a selection screen (FIG. 24) for selecting a device from which the automatic mode function is ported (FIG. 25 “return”. ") Is pressed.

  In the present embodiment, the first device 200 is a device at the transplantation source of the automatic mode function, and the second device 300 is a device at the transplantation destination of the automatic mode function.

  Next, the change point detection unit 103 of the server 100 extracts the log information corresponding to the device ID of the first device 200 selected as the device of the porting source from the device log DB 107, and extracts the extracted log information. It is determined whether or not there is a deterioration point at which an abnormality occurs in the sensor value (step S32).

  Here, processing in which the change point detection unit 103 of the server 100 detects a deterioration time point will be described using FIG.

  FIG. 26 is a diagram for describing a process of detecting a deterioration time point and a deterioration prediction time point from log information of the first device in the present embodiment. In FIG. 26, the solid line indicates the abnormality occurrence rate of the sensor value, the vertical axis indicates the abnormality occurrence rate, and the horizontal axis indicates the date.

  The change point detection unit 103 calculates, for example, an abnormality occurrence rate of the sensor value of each day based on log information in the device log DB 107 regarding the abnormality of the sensor value. The abnormality occurrence rate indicates how often the sensor value imbalance or numerical abnormality occurs in the daily log information. Then, when there is a day when the abnormality occurrence rate is equal to or higher than a predetermined value, for example, 70% or more, the change point detection unit 103 determines that there is a deterioration time when an abnormality occurs in the sensor value.

  Note that, for example, when the difference between two sensor values having correlation with each other is equal to or larger than a predetermined value, the change point detection unit 103 may determine that the balance of the sensor values has been lost. For example, there is a correlation between the outside air temperature and the room temperature, and when the room temperature is extremely low or high with respect to the outside air temperature, there is a possibility that an abnormality has occurred in either the outside air temperature sensor or the room temperature sensor. is there. Therefore, when the difference between the outside air temperature and the room temperature is equal to or more than a predetermined value, the change point detection unit 103 determines that the sensor value imbalance has occurred.

  In addition, for example, when a certain sensor value exceeds a predetermined numerical range, the change point detection unit 103 may determine that a numerical abnormality has occurred. For example, if the outside temperature measured in summer is 5 degrees, there is a possibility that an abnormality has occurred in the outside temperature sensor. Therefore, when the outside air temperature exceeds a predetermined numerical range (for example, a range of 20 degrees to 40 degrees), the change point detection unit 103 determines that a numerical abnormality of the sensor value has occurred.

  If it is determined that there is no point in time of deterioration at which a sensor value is abnormal (NO in step S32), automatic mode function generation unit 102 extracts the latest automatic mode function from automatic mode function DB 106 (step S33).

  On the other hand, when it is determined that there is a deterioration time point at which an abnormality occurs in the sensor value (YES in step S32), change point detection unit 103 determines the deterioration prediction time point at which the automatic mode function has changed before the deterioration time point. Is determined (step S34).

  In FIG. 26, the broken line indicates the similarity of the automatic mode function, the vertical axis indicates the similarity, and the horizontal axis indicates the date.

  The change point detection unit 103 calculates the degree of similarity between the automatic mode functions before and after the update, and detects the day when the degree of similarity of the automatic mode function is less than or equal to a predetermined value. Determine if it is or not. The similarity is expressed in the range of 0-1. As the similarity is closer to "1", it is determined that the automatic mode functions before and after updating are similar. For example, when the automatic mode function is updated every week, the change point detection unit 103 calculates the similarity between the current automatic mode function and the automatic mode function one week ago.

  As shown in FIG. 26, for example, when the first summer and the first winter from the start of use are reached, the default automatic mode function is updated to the automatic mode function reflecting the user's preference, so The similarity of the mode functions is greatly reduced. On the other hand, since the automatic mode function once established is kept as it is for several years, the change in the automatic mode function before and after updating is small, and a state of high similarity is maintained.

  Signs of degradation may appear on the device before it degrades. For example, if there is a defect in the sensor value of the device and the user changes the setting according to the operation instruction, the automatic mode function is updated, and the similarity between the automatic mode functions before and after the update decreases. In this way, it is possible to eliminate the incorrect automatic mode function from the point of deterioration to the point of deterioration prediction by detecting the point of time when the automatic mode function has changed from the previous one as the deterioration prediction point. It becomes.

  The change point detection unit 103 determines, among the plurality of automatic mode functions, whether or not there is a deterioration prediction time point in which the automatic mode function generated before the deterioration time point has changed from the previous automatic mode function. As shown in FIG. 26, although the similarity between the automatic mode function before and after the update is reduced by a predetermined value or more immediately before the point of deterioration, this is because the sensor value is abnormal. Not detected as a point of warning.

  Here, if it is determined that the deterioration prediction time does not exist before the deterioration time (NO in step S34), automatic mode function generation unit 102 generates the automatic mode function based on the log information before the deterioration time. (Step S35). The automatic mode function generation unit 102 may extract the automatic mode function stored immediately before the point of deterioration from the automatic mode function DB 106.

  On the other hand, when it is determined that the deterioration sign time point exists before the deterioration time point (YES in step S34), change point detection section 103 determines whether or not the user's use status has changed at the deterioration sign time point (step S36). The change in the use condition of the user indicates, for example, a change in family structure or a change in arrangement of furniture. The change point detection unit 103 determines whether the change in the automatic mode function is due to a sign of deterioration or due to a change in the use condition of the user. The similarity between the automatic mode functions before and after the update is reduced not only when the first device 200 is degraded but also when the user's use status changes. If the change in the automatic mode function is caused by the change in the user's usage status, the automatic mode function may be generated using log information from the point of deterioration to the point in time of deterioration.

  Note that the change point detection unit 103 determines whether there is a change in the family configuration or a change in the arrangement of the furniture by using a sensor value from a human sensor or a warm sensor included in the first device 200. can do. Further, in the process of step S36, the portable terminal 400 may display a confirmation screen for confirming whether or not the use state of the user has changed at the time of the deterioration sign in the past, and may receive an input operation by the user. The server 100 may receive, from the portable terminal 400, information on whether or not the usage state of the user has changed.

  If it is determined that the user's use status has changed at the deterioration prediction time (YES in step S36), automatic mode function generation unit 102 generates an automatic mode function based on log information before the deterioration time (step S35). If there is a change in the use status of the user at the deterioration prediction time, the automatic mode function generation unit 102 reads out the automatic mode function from the automatic mode function DB 106 at the time of the change in the use status of the user. You may use the automatic mode function as it is.

  On the other hand, when it is determined that the user's usage status has not changed at the deterioration prediction time (NO in step S36), automatic mode function generation section 102 generates the automatic mode function based on log information prior to the deterioration prediction time. (Step S37). The automatic mode function generation unit 102 may extract the automatic mode function stored immediately before the deterioration prediction time point from the automatic mode function DB 106.

  Next, the performance difference correction unit 104 extracts a correction function for correcting the difference between the first device 200 and the second device 300 from the correction function storage unit 105, and performs steps based on the extracted correction function. The automatic mode function extracted or generated in the process of S33, step S35 and step S37 is converted to the automatic mode function of the second device 300 (step S38).

  Next, the communication unit 101 transmits the automatic mode function converted by the performance difference correction unit 104 to the second device 300 (step S39).

  Next, the communication unit 301 of the second device 300 receives the converted automatic mode function transmitted by the server 100 (step S40).

  Next, the communication unit 301 overwrites the received automatic mode function on the automatic mode function storage unit 303, and updates the automatic mode function (step S41).

  When a series of processing for porting the automatic mode function of the first device 200 to the second device 300 is completed, the communication unit 301 of the second device 300 performs registration processing of the second device 300. A completion notification may be sent to the mobile terminal 400 that is present.

  FIG. 27 shows an example of a notification screen for notifying the user that reflection of the automatic mode function is completed.

  The communication unit 301 of the second device 300 transmits, to the portable terminal 400, notification information for notifying that the automatic mode function of the first device 200 is reflected in the automatic mode function of the second device 300. The communication unit 401 of the portable terminal 400 receives the notification information transmitted by the second device 300. When the notification information is received, the input / output unit 403 displays a notification screen for notifying that the automatic mode function of the first device 200 is reflected in the automatic mode function of the second device 300.

  The input / output unit 403 of the portable terminal 400 displays a notification screen shown in FIG. In the notification screen shown in FIG. 27, the device at the porting source of the automatic mode function is displayed, and the user is notified that the reflection of the automatic mode function of the second device 300 is completed.

  In the present embodiment, when replacing the device, the automatic mode function generated by the old device is ported to the new device after correcting the performance difference between the old device and the new device. In addition, when the automatic mode function of the old device is ported to the new device, the deterioration of the old device, the sign of deterioration or the change in the use condition of the user is detected, and the detection mode generates the automatic mode function of the old device Used for

  As a result, it is possible to transplant the automatic mode function that the user needs in the new device, taking into consideration the change in the automatic mode function according to the deterioration, the deterioration sign, or the change in the use condition of the user.

  Here, when the automatic mode function of the first device 200 is ported to the second device 300, the automatic mode of the first device 200 is based on the performance difference between the first device 200 and the second device 300. The difference between the control contents of the second device 300 in the automatic mode will be described depending on whether the function is corrected or not.

  FIG. 28 corrects the automatic mode function of the first device based on the performance difference between the first device and the second device when porting the automatic mode function of the first device to the second device It is a figure for demonstrating the control content in the automatic mode of the 2nd apparatus in case there was no. FIG. 29 corrects the automatic mode function of the first device based on the performance difference between the first device and the second device when porting the automatic mode function of the first device to the second device It is a figure for demonstrating the control content in automatic mode of the 2nd apparatus in a case.

  FIG. 28 and FIG. 29 show setting examples of the first device 200 and the second device 300 on the day when the outside air temperature is 30 degrees or more. The first device 200 and the second device 300 are air conditioners. In addition, the graph is represented by three axes of the set temperature, the set air volume, and the outside air temperature. When new home appliances are purchased after being used for many years like home appliances, the performance improvement may increase the performance difference between the first apparatus 200 and the second apparatus 300. Therefore, as shown in FIG. 28, when the automatic mode function of the first device 200 is ported to the second device 300 without correcting the performance difference between the first device 200 and the second device 300, When the second device 300 is controlled by the same control as that of the device 200, the range of the set air volume becomes strong, which may cause the user to feel uncomfortable, such as being too cold. On the other hand, as shown in FIG. 29, when the automatic mode function of the first device 200 is ported to the second device 300 by correcting the performance difference between the first device 200 and the second device 300, Even if the second device 300 is controlled by the same control as that of the device 200, the set air volume is corrected to an appropriate range, and it is possible to perform control so as not to be too cold.

(Modification)
(1) In the present embodiment, the first device 200 and the second device 300 are air conditioners, but may be other devices. The first device 200 and the second device 300 may be cooking appliances such as a washing machine and a rice cooker. For example, if the first device 200 and the second device 300 are washing machines, they have a function of storing the setting contents unique to the user, and the setting contents unique to the user of the old washing machine are transplanted to the new washing machine. This allows the user to perform the washing with the same setting as the old washing machine, without the trouble of getting used to feeling the performance of the new washing machine.

  (2) In the present embodiment, the information to be notified to the user is notified by the portable terminal 400, but the portable terminal 400 may not notify. The notification may be made by a smart device worn by the user, or by a smart speaker if it is determined that the user is at home. As a result, even when the user does not have the portable terminal 400, it is possible to notify by means of a smart device or a smart speaker around the user.

  (3) In the present embodiment, the automatic mode function generation unit 102 updates the automatic mode function using one week's worth of log information, but the log information used is not one week's worth of log information. It is also good. The automatic mode function generation unit 102 may update the automatic mode function using three weeks of operation history. As a result, the user has different life patterns for each day of the week, and even if an irregular schedule occurs, irregular control and normal control can be classified.

  (4) In the present embodiment, the automatic mode function is constantly updated, but when the log information is changed a predetermined number of times, the automatic mode function may be updated using the changed log information. For example, when it is determined that the log information has been changed ten times, the automatic mode function generation unit 102 may set the changed log information as a learning target. As a result, when the automatic mode function does not change for a predetermined period, the cost of the server 100 that generates the automatic mode function can be reduced. Further, the modification (4) may be designed in combination with the modification (3).

  (5) In the present embodiment, the point of deterioration is determined based on an abnormality occurrence rate indicating a ratio of occurrence of imbalance of sensor values or numerical abnormality of sensor values with respect to log information of one day, but a specific sensor value The numerical abnormality of may be included in determination. This makes it possible to detect a clear abnormality when the abnormality regularly occurs but the rate of occurrence of the abnormality is low.

  (6) In the present embodiment, replacement of equipment disposed in the same room is described, but the equipment control system may be applied to the case of transferring equipment to a different room. For example, the device control system may be applied when transferring a device from a living room to a bedroom. At this time, for example, using the sensor value and the operation history, the reason for changing the layout or setting the wind direction of the user is estimated. As a result, not only the performance difference between the old device and the new device but also control in accordance with the layout becomes possible, and control that reflects the user's preference, such as designation of a place where wind is not desired to be applied, becomes possible.

  Further, when the device is transferred to a different room, the automatic mode function generation unit 102 may correct the automatic mode function based on the environment of the transfer location such as the size of the room, for example.

  (7) In the present embodiment, although the automatic mode function of one device is ported to one device, the automatic mode function of one device is two or more units installed in different rooms. It may be transplanted to a device. For example, when a plurality of persons use a plurality of devices by coexistence of a plurality of persons who used different devices, an automatic mode function of each device may be ported to the plurality of devices. This enables control in which the preferences of each user of a plurality of devices are fused.

  (8) In the present embodiment, the user who is in the room may be further identified by grasping the at-home condition, and the automatic mode function may be generated based only on the operation history of the identified user. This makes it possible to further improve the accuracy and enables control tailored to the user.

  (9) In the present embodiment, although the automatic mode function of one device is ported to one device in the same room, the automatic mode function of two or more devices installed in different rooms. May be ported to a single device. For example, when a user living with a family migrates to a studio apartment to live alone, the automatic mode function of the living air conditioner and the automatic mode function of the bedroom air conditioner are integrated into one air The automatic mode function of the air conditioner in the living room and the automatic mode function of the air conditioner in the children's room may be integrated and transplanted into one air conditioner. By porting the automatic mode function of each room's equipment to one equipment, the preference of one user can be extracted and reflected in the control of one equipment.

  (10) In the present embodiment, notification information for notifying the user that the automatic mode function of the first device 200 has been updated is transmitted to the portable terminal 400 when the update is completed, but after the update is completed It may be transmitted to the first control device 500 or the portable terminal 400 at the time of the first ON operation. This saves the trouble of viewing notification information when the user is not operating.

  (11) In the present disclosure, although a model (automatic mode function) is created using a regression function, the present invention is not limited to this. For example, there is a method of creating a feature amount from log information, and generating a model (automatic mode function) through a classifier. In addition, models (automatic mode functions) include neural networks (including deep learning using multi-layered neural networks), genetic programming, decision trees, Bayesian networks, or support vector machines (SVMs) used in machine learning. Can be considered as

  (12) Some or all of the components constituting each of the above-described devices may be configured from one system LSI (Large Scale Integration: large scale integrated circuit). The system LSI is a super-multifunctional LSI manufactured by integrating a plurality of components on one chip, and more specifically, a computer system including a microprocessor, a ROM, a RAM, and the like. . A computer program is stored in the RAM. The system LSI achieves its functions as the microprocessor operates in accordance with the computer program.

  Moreover, each part of the component which comprises each said apparatus may be integrated into 1 chip separately, and 1 chip may be integrated so that one part or all may be included.

  Further, although a system LSI is used here, it may be called an IC, an LSI, a super LSI, or an ultra LSI depending on the degree of integration.
