Needless to say, it may be recorded on a medium.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be described first. The present invention determines the use priority of home appliances according to the environmental conditions at an arbitrary time in a general household or a consumer building of a power consumer, and based on the determined use priority, the operating state of each home appliance It is related to the mechanism to control.

  That is, the first main feature of the present invention is that the amount of electric power used by the home appliance at a predetermined time and the time zone, season, day of the week, indoor / outdoor temperature, indoor / outdoor humidity, weather, illuminance, etc. Information on various environmental conditions is measured, and machine learning is performed based on the measured information to estimate the usage probability of home appliances in various environmental conditions. It is possible to associate with the estimated value.

  Furthermore, the second main feature of the present invention is based on the estimated value of the use probability of the home appliance associated with each environmental condition as described above, and the use priority is higher for a home appliance having a higher use probability in a certain environmental condition. As higher household appliances, prioritize each household appliance according to the probability of use, and when it becomes necessary to stop some household appliances, select a household appliance with a lower priority and automatically stop it It is possible to make it possible.

  More specifically, the main feature of the present invention is that it is configured according to the following configuration requirements.

  (1) First, the amount of power used by each home appliance at each time measured at predetermined intervals and the environmental conditions such as time zone, season, day of the week, indoor / outdoor temperature, indoor / outdoor humidity, weather, illuminance, etc. Is used as a variable, a multivariate analysis is performed, and a home appliance usage pattern model in which usage patterns of home appliances are modeled using environmental conditions as parameters is generated.

  (2) After that, the use probability of each household electrical appliance in the said environmental condition is estimated by fitting the time and environmental condition which wants to determine the priority of a household electrical appliance to the produced said household electrical appliance usage pattern model.

  (3) And, household appliances with higher usage probability under certain environmental conditions are considered to have higher usage priority, and conversely, household appliances with lower usage probability under the environmental conditions have lower usage priority. Consider it a household appliance.

  (4) After that, when it becomes necessary to stop the operation of some home appliances from the viewpoint of energy saving or the like, the operation is stopped by selecting a home appliance with a low use priority.

  Thus, in addition to the calendar information of the time, time zone, season, and day of the week, the use of home appliances with higher accuracy is considered, taking into consideration various environmental conditions including indoor and outdoor temperatures, indoor and outdoor humidity, weather, and illuminance. It is possible to estimate the rank, and it is possible to obtain an effect that it is possible to set the usage state of the home appliance most desirable for the electric power consumer.

  Further description is as follows. As mentioned above, as a conventional energy-saving measure for general households and residential buildings of electricity consumers, as described above, set household appliances with a low priority for use and use the amount of power used when contract power is reached. If it is necessary to stop some home appliances in order to reduce battery consumption, it is determined that the use priority is low based on the preset use priority of the home appliance. A technique of automatically stopping the equipment was used.

  However, for electric power consumers, household appliances that should be given priority for use and those that should be suspended vary depending on environmental conditions such as time of day, season, day of the week, indoor / outdoor temperature, indoor / outdoor humidity, weather, and illuminance. In spite of this, the conventional mechanism of setting the usage priority of each home appliance in advance regardless of the environmental conditions stops home appliances that are not necessarily low priority for the power consumer. The usage priority of home appliances does not sufficiently reflect the usage status of home appliances desired by power consumers.

  On the other hand, in the present invention, first, the amount of power used by the home appliance at each time and the environmental conditions such as time zone, season, day of the week, indoor / outdoor temperature, indoor / outdoor humidity, weather, and illuminance at the time. Based on these measured data, machine learning is performed to estimate the usage probability of household appliances under various environmental conditions as a household appliance usage pattern model that models the usage pattern of each household appliance. Make an association.

  Thereafter, based on the estimated value of the use probability of the home appliance associated with each environmental situation, the home appliance that is estimated to have a high use probability under a certain environmental condition is set to have a high use priority, and the use probability is low. The household appliances estimated to be used as household appliances with low usage priority are prioritized according to the usage probability for each household appliance under each environmental condition, and a household appliance usage priority registration table is created.

  When it is necessary to stop some of the home appliances during actual use of the home appliances under certain environmental conditions, the use priority of the home appliances created using the environmental conditions as parameters is used. By referring to the degree registration table, a home appliance with a low priority is extracted, and the home appliance is automatically stopped.

  By using the power consumption of home appliances for each of various environmental conditions as input data in such machine learning, it is possible to prioritize the use of home appliances that reflect the environmental conditions. Thus, when it becomes necessary to stop some home appliances in order to meet the purpose of reducing the amount of power used to a certain required level, priority is given to the use of home appliances under the environmental conditions at that time. It is possible to more accurately select household appliances with lower degrees and stop the operation of the applicable household appliances. Even if some household appliances stop operating, the environmental conditions at that time Accordingly, it is possible to realize the usage state of the home appliance most desired by the electric power consumer.

  The indoor control subsystem 10 performs the operation of transmitting the measurement data notification information as described above to the device control server 20 at any time as appropriate.

  On the other hand, in cooperation with the indoor control subsystem 10, the device control server 20 having a function of controlling the operations of the home electric appliances 1a to 1h of the power consumers of the indoor control subsystem 10 is shown in the flowchart of FIG. As shown in FIG. 1, first, the power consumption and environmental conditions of the home appliances 1 a to 1 h that are periodically transmitted as measurement data notification information at predetermined intervals from the home communication unit 8 of the indoor control subsystem 10. Is sequentially stored in the usage status table 24a in which history information related to the relationship between the power consumption in the database 24 and the environmental conditions is stored in association with each indoor control subsystem 10 (step S201). Further, every time the measurement data notification information is received, or in some cases, every time when an appropriate time point is reached, the amount of data related to a certain indoor control subsystem 10 stored in the usage status table 24a of the database 24 ( It is checked whether or not the information on the amount of power used and environmental conditions has reached a preset data amount threshold (step S202).

  When the amount of data related to a certain indoor control subsystem 10 accumulated in the usage status table 24a of the database 24 has not reached the data amount threshold or more (No in step S202), the power of the indoor control subsystem 10 Since the amount of data required for analyzing the usage priority of each consumer electronics device 1a to 1h of the consumer is still insufficient, the indoor control sub is concerned until the data amount reaches the data amount threshold value or more. The system 10 waits for the next measurement data notification information to be transmitted.

  On the other hand, when the data amount related to a certain indoor control subsystem 10 accumulated in the usage status table 24a of the database 24 has reached the data amount threshold or more (Yes in step S202), the use probability of the device control server 20 The estimation unit 21 is activated, and the use probability estimation unit 21 stores the measurement data notification information transmitted this time from the home communication unit 8 of the indoor control subsystem 10 and the use status table 24a of the database 24. With regard to past history information (information relating to the power consumption and environmental conditions of each home appliance 1a to 1h), a calculation such as multivariate conversion is performed, and machine learning relating to the correlation between the power consumption and the environmental conditions is performed. The usage probability of each home appliance 1a-1h under each environmental condition based on the learning algorithm is estimated (step S). 03).

  Thereafter, the use priority determination unit 22 is activated, and the use priority determination unit 22 determines each home electric appliance 1a to 1h based on the estimation result of the use probability of each home appliance 1a to 1h under each environmental condition. Is used in accordance with each environmental condition (step S204). In other words, home appliances that use a large amount of power in certain environmental conditions, that is, home appliances that have a high use probability, are classified as home appliances that have a high priority for use. Devices are classified as household electrical appliances with lower usage priority.

  Next, the usage priorities of the household electrical appliances 1a to 1h determined corresponding to the environmental conditions are set and registered in the usage priority registration table 24b of the database 24 (step S205).

  Furthermore, in order to prepare for the reception of the next measurement data notification information, each household electrical appliance 1a ~ accumulated in the usage status table 24a of the database 24 used for determining the usage priority of each household electrical appliance 1a ~ 1h. Of the history information related to the power consumption and environmental conditions for 1 h, only a predetermined amount of data (or only one oldest information) is deleted in order from the oldest information in the past.

  As described above, when the use priorities of the latest home appliances 1a to 1h are set and registered in the use priority registration table 24b of the database 24 in accordance with each environmental condition, the device control unit 23 is then activated to control the device. In the unit 23, the total amount of power used by the home appliances 1a to 1h in the indoor control subsystem 10 of the power consumer transmitted from the home communication unit 8 of the power consumer is, for example, energy saving or contract power It is checked whether or not a preset power amount threshold is exceeded from the viewpoint of the amount or the like (step S206).

  The total amount of power used by each of the home appliances 1a to 1h in the indoor control subsystem 10 of the power consumer that has been transmitted from the home communication unit 8 of the power consumer did not exceed the power threshold. In this case (No in step S206), it is determined that it is not currently necessary to perform the ON / OFF control of the home appliances 1a to 1h in the indoor control subsystem 10 of the power consumer, and the device control server The process of 20 ends.

  On the other hand, when it is detected that the total amount of power used by each of the home appliances 1a to 1h in the indoor control subsystem 10 of the power consumer has exceeded the power amount threshold value (yes in step S206), device control The unit 23 refers to the use priority registration table 24b of the database 24 so that the total amount of power consumption expected to be used in the future does not exceed the power amount threshold value, and Based on the learned result, one or more home appliances that are assumed to have low use priority in the current environmental conditions are required among the home appliances 1a to 1h in the indoor control subsystem 10 of the power consumer. As many as the number to be stopped are extracted as stop candidate devices whose operation should be stopped (step S207).

  Here, when there is no stop candidate device to be extracted, or when processing has been performed for all the stop candidate devices that have been extracted even if they exist (no in step S208). ), Assuming that all the processes to be performed on the device control server 20 side have been completed, the process proceeds to step S213.

  On the other hand, if the extracted stop candidate device still exists (Yes in step S208), the device control unit 23 generates a control instruction that instructs to stop the operation of the stop candidate device, and It transmits via the communication network 30 with respect to the domestic communication part 8 in the indoor control subsystem 10 of a consumer. In addition to the information indicating the stop instruction of the operation of the home appliance specified as the stop candidate device, the control instruction is given an identifier indicating the home appliance whose operation should be stopped, and the control instruction is transmitted to the power consumer. An instruction to display the screen on the display unit 6 is also included.

  When a control instruction like this is transmitted from the device control unit 23 on the device control server 20 side, as shown in the flowchart of FIG. 2A, the in-home communication unit 8 of the indoor control subsystem 10 A control instruction for instructing to stop the designated stop candidate device from the control server 20 is received (step S104), and the received control instruction (stop candidate device stop instruction) is displayed on the display unit 6; The electric power consumer is notified that the operation of the home appliance designated as the stop candidate device among the home appliances 1a to 1h is stopped (step S105). Further, the home communication unit 8 sends the control instruction received from the device control server 20 to the power measuring units / control units 4a to 4h connected to the outlets of the home appliances 1a to 1h. Instructed to stop the operation by broadcasting the indoor radio wave simultaneously and stopping the power supply to the corresponding home appliance.

  The power measuring units / control units 4a to 4h that have received the control instruction transmitted simultaneously from the home communication unit 8 have the identifier of the home appliance given to the control instruction set to the home appliance to be controlled by themselves. If it is not applicable, the control instruction is ignored. On the other hand, if it is applicable, the power supply to the home appliance to be controlled is stopped. Is stopped (step S106).

  Here, the electric power consumer who has visually recognized the content of the received control instruction displayed on the display unit 6 of the indoor control subsystem 10 stops the operation of the home appliance specified as the stop candidate device in the control instruction. The home communication unit 8 receives the control instruction in the operation unit 7 of the indoor control subsystem 10 in preparation for the case where it is determined that it is not desired and the operation of the household electrical appliance designated as the stop candidate device is resumed. Thereafter, it is confirmed whether or not a predetermined time has passed (step S107).

  When the predetermined time has not yet elapsed (no in step S107), the power consumer operates the operation unit 7 to resume the operation of the home appliance designated as the candidate for stoppage. Or, it is confirmed whether or not the home electric appliance designated as the candidate for stoppage is in a stopped state (step S108). When the household electrical appliance designated as the candidate for stoppage is in a stopped state (yes in step S108), the process returns to step S107 and checks whether or not the predetermined time has elapsed. repeat.

  On the other hand, from the operation unit 7 until the predetermined time elapses without stopping the home appliance specified as the stop candidate device until the predetermined time elapses. If the power consumer detects that there is an operation to restart the operation of the stop candidate device (no in step S108), it is assumed that the stop candidate device has been stopped by mistake. The home communication unit notifies the device control server 20 that the stop candidate device has been restarted as a result of erroneously instructing stoppage of the home appliance that the power consumer does not want to stop. 8 through the communication network 30 (step S109).

  On the other hand, if the home appliance specified as the stop candidate device continues to be stopped even after the predetermined time has elapsed (Yes in step S107), the home appliance specified as the stop candidate device Since it may be determined that there is no problem even if the device is stopped, no further notification to the device control server 20 is performed. However, even in such a case, you may make it notify the apparatus control server 20 side that there was no problem by stopping the household electric appliance designated as the said stop candidate apparatus.

  Here, in the device control server 20 that has transmitted a control instruction to the in-home communication unit 8 in the indoor control subsystem 10 of the power consumer, the indoor control subsystem 10 notifies the stop candidate device to be restarted. 2B, in step S210 of the flowchart of FIG. 2B, the control instruction is waited for a predetermined time after the transmission of the control instruction, and the control instruction transmission destination indoor control subsystem 10 in the home The state of monitoring the presence / absence of information from the communication unit 8 is continued. That is, based on the presence / absence of information from the home communication unit 8 in the indoor control subsystem 10, the operation of the home appliance specified as the stop candidate device in the control instruction is stopped until the predetermined time elapses. Whether or not the home appliance specified as the stop candidate device has been restarted until the fixed time elapses, or the home appliance specified as the stop candidate device is Information indicating whether it has not been stopped is acquired (step S210).

  Thereafter, based on the notification from the home communication unit 8 in the indoor control subsystem 10 that is the transmission destination of the control instruction, whether or not the home appliance designated as the stop candidate device is restarted within the predetermined time. (Step S211), if it has been stopped and has not been restarted (no in step S211), based on the result of machine learning so far, the environment of the power consumer Regarding the usage priority of the home appliance corresponding to the stop candidate device registered in the usage priority registration table 24b of the database 24 corresponding to the condition, it is registered in a state desirable for the power consumer. Determination is made, the process returns to step S208, and the process of searching for the presence or absence of the next stop candidate device is repeated.

  On the other hand, if the home appliance designated as the candidate for stoppage has been restarted or not stopped before the predetermined time has elapsed (step S3) Yes in S211), regarding the use priority of the home appliance corresponding to the stop candidate device registered in the use priority registration table 24b of the database 24, it is determined that it is necessary to register and change the stop. Change the use priority of the home appliance corresponding to the candidate device to a higher priority, or set the database 24 so that the home appliance corresponding to the stop candidate device is excluded from the target of the stop candidate device. The use priority registration table 24b is rewritten (step S212). Thereafter, the process returns to step S208, and the process of searching for the presence or absence of the next stop candidate device is repeated.

  The above process is repeated until control completion or no stop candidate devices are present, and if it is determined in step S208 that no stop candidate devices exist (no in step S208), finally, a series of The process is accumulated and recorded on the database 24 as control data indicating the exchange with the indoor control subsystem 10 (step S213), and all processes in the device control server 20 are terminated.

  By performing the operations as described above, prioritizing the use of the home appliances 1a to 1h reflecting the environmental conditions by machine learning in advance and reducing the amount of power used to the level required in advance. In addition, when it becomes necessary to stop some of the household electrical appliances, the household electrical appliances 1a to 1h are more accurately selected from the household electrical appliances 1a to 1h under the environmental conditions at the time, and the corresponding household electrical appliances It is possible to realize the usage state of the home appliance most desired by the electric power consumer while stopping the operation and satisfying the requirements such as the required power saving and the contracted electric energy.

  In the flowchart of FIG. 2, after transmitting a control instruction to stop the stop candidate device from the device control server 20 to the indoor control subsystem 10 side in step S209, the indoor control subsystem 10 determines a predetermined time. Until the time elapses, the electric power consumer operates the operation unit 7 to monitor whether or not the stop candidate device is turned on again and restarted. In S210, whether or not information indicating a restart regarding the stop candidate device is notified from the in-home communication subsystem 8 of the indoor control subsystem 10 until a predetermined time has elapsed after the transmission of the control instruction. Although the case of monitoring has been described, the present invention is not limited to such a case.

  For example, the process of monitoring the passage of a predetermined time on the indoor control subsystem 10 side may be omitted, and the time monitoring as to whether or not the predetermined time has passed may be performed only on the device control server 20 side.

  Alternatively, instead of performing the process of notifying the device control server 20 of information indicating the restart related to the stop candidate device from the home communication unit 8 of the indoor control subsystem 10, the device control server 20 side performs a certain cycle. Of the amount of power used by each home appliance 1a to 1h periodically transmitted from the home communication unit 8 of the indoor control subsystem 10, the power used by the home appliance specified as the stop candidate device in the control instruction It is determined whether or not the stop candidate device has stopped by continuously monitoring the amount for the predetermined time, and the stop candidate device corresponds to the stop candidate device for the power consumer Stopping home appliances is undesirable, either when it is restarted, or when the stop candidate device stops accidentally with a non-stop candidate home appliance As an instruction is given, it may be identified whether if at all not stopped.

  As described above, when the stop candidate device is restarted immediately after being stopped by continuously monitoring for the predetermined time, or when the stop candidate device is not stopped, such a case is required. As a result of machine learning of the environmental conditions, the establishment of use of the home appliance indicated by the candidate device to be stopped and the determination of the use priority are erroneously set and registered in the use priority registration table 24b of the database 24. It is determined that erroneous information that is undesirable for power consumers is set and registered in the usage priority, and the stop candidate device in the environmental condition is set so that the usage priority is more accurate. It is possible to change the use priority of the indicated home appliance to a higher priority, or to perform a feedback operation such as excluding it as a candidate for a stop candidate It made.

  In the present embodiment, as a control instruction from the device control server 20 to the indoor control subsystem 10, the power supply of the home appliance corresponding to the designated stop candidate device is stopped and the operation of the home appliance is stopped. However, the present invention is not limited to such a case. As the control instruction for reducing the total power consumption of the home appliances 1a to 1h in the indoor control subsystem 10, for example, a power supply voltage or a power supply current supplied to a home appliance with a low use priority is An instruction to reduce the value to a predetermined value appropriately corresponding to each home appliance may be output.

  Next, in step S203 of the device control server 20 in FIG. 2B, each of the environmental conditions based on the machine learning result relating to the association between the power consumption and the environmental conditions in the indoor control subsystem 10 of the power consumer. About a method of estimating the use probability of household appliances 1a-1h, a specific Example is described more concretely using FIG. 3, FIG.

  FIG. 3 is a schematic diagram showing an example of temporal transition of the usage status of each home appliance and the outside air temperature and illuminance in the indoor control subsystem of the power consumer. For simplicity of explanation, the home appliance 1a About 1h, the case of three home appliances 1, home appliance 2 and home appliance 3 is shown, and only environmental temperature and illuminance are shown as environmental conditions, and the time zone is 24 hours from 12:00 to midnight. Only time is shown.

  In the example shown in FIG. 3, the household electrical appliance 1 is in use from 12:30 to 18:00, and the household electrical appliance 2 is from 12:00 to 14:00, from 16:00 to 18:00, and 20:00 It shows that the home appliance 3 is in use from 3:30 until 22:00, and the home appliance 3 is in use from 18:30 to 23:00. In addition, the outside air temperature reaches a peak at 13:00 and then gradually decreases. In addition, the illuminance gradually decreases from 17:00 in the evening, and shows a state in which the illuminance is almost zero at 20:00.

  FIG. 4 is a conceptual diagram showing the concept of a usage probability estimation model of the usage establishment estimation unit 21 that estimates the usage probability of each household electrical appliance under each environmental condition, and the environment of the outside air temperature T and illuminance L at time t. The usage status table 24a of the database 24 showing the history of the usage status of the household appliances at the time t-1, the usage household appliances at the time t-2, and the usage status and environmental conditions of the household appliances in the past. The example which estimates the use probability estimated value of each apparatus (the household appliance 1, the household appliance 2, the household appliance 3 in the case of FIG. 3) with the usage probability estimation model using the method of multivariate analysis is shown.

  In other words, as shown as a concept in FIG. 4, in this home appliance control system, environmental conditions such as current time zone, season, weekday / holiday (day of the week), indoor / outdoor temperature, indoor / outdoor humidity, weather, illuminance, etc. Household appliances in use in the time zone to be used, environmental conditions in each past time zone than the time zone to be controlled, and household appliances in use as explanatory variables, and the use probability of each home appliance in the next time zone As a covariate, modeling based on multivariate analysis (for example, neural network, hierarchical Bayesian estimation (eg 90% confidence interval), multiple response analysis, multiple regression analysis, etc.) The machine learning of the usage pattern of each home appliance in the system 10, that is, the probability that each home appliance is used.

  In addition, when there is something closely related to home appliances, the closely related home appliances should not be treated as individual home appliances, but should be databased as combined devices that use both home appliances simultaneously. I am doing so.

  In the home appliance control system, in the state immediately after installation, as described above, the database 24 of the device control server 20 stores neither the use probability estimation model nor the data regarding the power consumption. During a certain period after installation, only data collection and machine learning are performed, and at the time when data exceeding a predetermined data amount threshold is accumulated in the usage status table 24a of the database 24, each environment Start the operation to estimate the usage probability of each household electrical appliance under the conditions, and at the stage where the estimated usage probability is obtained, perform the process of determining the usage priority of each household electrical appliance under each environmental condition Yes.

  In addition, after a certain period of time has elapsed since the installation of the home appliance control system, as described above, the home appliances 1a to 1h are used as measurement data notification information from the home communication unit 8 of the indoor control subsystem 10. It is not always necessary to perform machine learning for estimating the use probability of each home appliance in the device control server 20 each time data regarding the electric energy and environmental conditions is transmitted.

  That is, since a certain amount of data is sequentially deleted from the past data used when the use probability is estimated once, it is transmitted from the home communication unit 8 of the indoor control subsystem 10. The latest data is sequentially accumulated in the usage status table 24a of the database 24, and when data exceeding a predetermined data amount threshold is accumulated, an operation for estimating the usage probability is performed, and machine learning is performed. The usage priority is determined based on the estimated value of the usage probability of each home appliance obtained as a result of the above, and updated and registered in the usage priority registration table 24b of the database 24. Here, the estimated value of the use probability of each home appliance and the result of machine learning itself may be stored in the database 24.

  As described above, when the usage priority of each home appliance is estimated, the communication network 30 as well as the amount of power used by each home appliance as well as the environmental conditions in the indoor control subsystem 10 of the power consumer are described. Are collected online and stored in the usage status table 24a of the database 24 together with the power consumption of each home appliance. Then, at the stage where data equal to or greater than a predetermined data amount threshold is accumulated in the usage status table 24a, first, the past use probability stored in the usage status table 24a for the usage probability in a certain environmental condition of a certain home appliance By comparing the usage pattern of the household electrical appliance under various environmental conditions, the usage probability of the household electrical appliance under the environmental condition is estimated as a continuous value within a range of 0 to 1.

  After the estimated value of the use probability of each home appliance is obtained, the use probability of each home appliance is compared, and the home appliance with the lower use probability is regarded as the home appliance with the lower use priority, Order the usage priority of each home appliance. Thus, when trying to stop the use of any home appliance under a certain environmental condition, a home appliance with a lower use priority under the environmental condition has a lower use probability than other home appliances. Therefore, it is possible to determine that the household electrical appliance is a candidate for suspension to be used as a candidate for suspension of use and to select the device with priority.

  The selection of the stop candidate device like this is based on the data indicating the past usage status of the home electric appliance of the electric power consumer. That is, in this household electrical appliance control system, as mentioned above, all are based on the past data (the electric power consumption and environmental conditions of each household electrical appliance 1a-1h) collected from the indoor control subsystem 10 of the electric power consumer. The electric power consumer 1a to 1h is controlled, and for example, specific numerical values related to the outdoor temperature and weather of the electric power consumer are also specified by the system designer of the home electric appliance control system. Is not determined and set in advance. As a result, wasteful power can be saved within the contracted power consumption range, for example, while the usage state of the home appliance desired by the power consumer is continued.

  Below, in order to make it easy to understand the operation of the home appliance control system, a specific embodiment for controlling the home appliance will be further described.

  As a first example, for example, when the outside air temperature is a high temperature of 28 degrees Celsius or higher in the evening hours of weekdays, as a state of use of home appliances, the living room is cooled by strong air from the air conditioner, In the kitchen, an explanation will be given of a case where it is likely that the contracted amount of commercial power of the electric power consumer will be exceeded when trying to use a microwave oven for dinner preparation.

  In such a case, as a result of referring to past data (data regarding environmental conditions and power consumption) stored in the usage status table 24a of the database 24, the device control server 20 uses the probability of use of the air conditioner during the time period. Is 0.3 and the use probability of the microwave oven is 0.8, and when it is found that the frequency of using the microwave oven is high, the time when the air conditioner is used by selecting the air conditioner as a candidate for stopping During this period, a control instruction for forcibly stopping the operation of the air conditioner is generated and transmitted to the indoor control subsystem 10 of the power consumer.

  Next, as a second embodiment, for example, it is a midnight time zone on weekdays, and in the living room, the lighting, the air conditioner, and the television are continuously operated over a long period of time longer than a predetermined fixed time. The case where the state which is carrying out has generate | occur | produced is demonstrated.

  In such a case, as a result of referring to past data (data regarding environmental conditions and power consumption) stored in the usage status table 24a of the database 24, the device control server 20 includes lighting, air conditioning, When it is found that the number of times that each household electrical appliance with the TV is continuously operated over a long period of time equal to or longer than the predetermined duration and that each household electrical appliance has a usage probability of 0.2 or less Therefore, it is determined that the lighting, air conditioner, and television home appliances are forgotten to be turned off, and a control instruction for forcibly stopping the operation of the lighting, air conditioning, and television home appliances is generated as a candidate for stoppage. Then, an operation of transmitting to the indoor control subsystem 10 of the power consumer is performed.

  In the first embodiment and the second embodiment, the indoor control subsystem 10 that has received the control instruction from the device control server 20 specifies a home appliance that has been designated as a stop candidate device within a predetermined time. If the operation of the home appliance has not been stopped at all, or if the operation of the household electrical appliance is started again, as described above, the device control server 20 can provide the feedback from the indoor control subsystem 10 after the control instruction, Past data stored in the usage status table 24a of the database 24, assuming that an erroneous control instruction not desired by the power consumer of the indoor control subsystem 10 is transmitted to the indoor control subsystem 10. Assuming that the usage probability estimated based on (environmental conditions and power consumption data) is incorrect, Update the contents registered in the usage priority registration table 24b of the equipment, take action to change or use priority exclude the relevant home device from the target of the stop apparatus candidates to a higher rank.

  In the above description regarding the operation example of the home appliance control system according to the present invention, the case where the operation of the home appliances 1a to 1h is controlled by the linkage operation between the indoor control subsystem 10 and the device control server 20 has been described. In some cases, as described above, a management control unit is provided in the indoor control subsystem 10 so that the above-described functions on the device control server 20 side are provided in the management control unit in the indoor control subsystem 10. In addition, the operations of the home appliances 1a to 1h may be controlled only by the indoor control subsystem 10.
