Further, each function of the above-described apparatus may be realized by combining a plurality of functions into one function unit, or may be realized by dividing one function into a plurality of functions.
The air conditioner 200 includes a detection unit 201, a control unit 202, and a communication unit 203.
The input / display device 300 includes a display unit 301 and an input unit 302.

  The air conditioning control device 100 receives temperature and humidity for the user based on the history of the set temperature set by the user output by the air conditioner 200 and the history of the environment value output by the environment value acquisition device 400. The control value is generated by dividing whether or not it is within the allowable range. By outputting the generated control value to the air conditioner 200, the air conditioning control device 100 controls the air conditioner 200 such that the set value becomes an allowable range and energy saving is compatible. The method of generating the control value will be described later.

  FIG. 3A is an example of an operation period table for setting the operation period of the air conditioning control device 100. The operation period table includes the operation start time, the operation end time, and the operation mode of the air conditioning control device 100. As the operation mode, either "heating" or "cooling" is set. The air conditioning control device 100 is operated in the mode set in the operation mode during the operation period from the operation start time set in the operation period table to the operation end time.

  FIG. 3D is an example of a set temperature change time table for setting a set temperature change time at which the control value determination unit 115 outputs a control value to change the set temperature of the air conditioner 200. In the example shown in FIG. 3D, the set temperature change time is three times a day at 10:00:00 (10 o'clock), 12:00:00 (12 o'clock), 15:00:00 (15 o'clock) Indicates that it is set to).

FIG. 3E is an example of a table showing the type of attribute and the calculation time obtained from the environment value history information in the dividing unit 113. The dividing unit 113 simultaneously calculates the attribute when calculating the setting value history information. In the example shown in FIG. 3E, the attributes "outside temperature OT of time ta of the day," room temperature RT of time ta of the day, "average outside temperature OTM of ts to te one day ago", "1 It indicates that the room temperature average RTM of ts to te of the previous day is used. The time used for calculation of each attribute is described in the column of “Calculation time” in FIG. 3E, and it is shown that the calculation time of each sex attribute can be set for each attribute. For example, for the attribute “outside temperature OT of time ta of the day,” it is indicated that the calculation time is set to ta = 07: 00: 00 (7:00:00).
In the example shown in FIG. 3E, for example, the calculation time of "the outside temperature OT of the time ta on the day" is one, but the calculation time may be plural. Similarly, the calculation time may be plural for other attributes. Further, the attribute is not limited to that shown in FIG. 3E, and any attribute can be used as long as it can be calculated from environmental value history information. For example, a thermal sensation index such as PMV (Predicted Mean Vote) or SET ^* (Standard New Effective Temperature: New Standard Effective Temperature) based on room temperature or humidity as an attribute may be used. . What is necessary when obtaining the thermal sensation index and is not acquired by the environmental value acquisition device 400 may use the one in which the fixed value is stored in the setting information storage unit 102, via the instruction unit 112. It may be calculated by the dividing unit 113. The thermal sensation index may use, for example, “PMV at time ta on the day” or “average value of PMV one day before”. The calculation of the attribute will be described later.

  FIG. 3F is an example of the type of attribute used when the division unit 113 divides setting value history information according to the value of the attribute. FIG. 3F shows that the setting value history information is divided by “the outside temperature OT of time ta”. The available use attribute is at least one of the attributes shown in FIG. The method of dividing the setting value history information will be described later. The information divided by the dividing unit 113 is not limited to the setting value history information, and both of the setting value history information and the environment value history information may be divided.

  FIG. 3G is an example of an identification boundary table for setting an identification boundary. The identification boundary table includes setting information of “feature amount type” and “use parameter of identification boundary”. The feature amount type indicates the type of use feature amount for the allowable range calculation unit 114 to calculate the allowable range. In the “Weibull” feature type shown in FIG. 3G, the Weibull distribution is applied to the analysis of the duration at each set temperature in the calculation of the feature described later, and the coefficient parameter of the Weibull distribution is used as the feature Is shown. Further, the parameter of the identification boundary is a parameter that defines the boundary for classifying the setting value into the allowable range group and the out-of-the-range group based on the calculated feature amount. The parameter of the identification boundary is determined, for example, by machine learning such as a SVM (Support Vector Machine) model or the like, in which the calculated feature amount is an explanatory variable and whether it is within tolerance or out of tolerance as a target variable. (A, b) of FIG. 3G are, for example, parameters that define a linear function. It should be noted that several combinations of feature amount types and use parameters of identification boundaries may be prepared in advance according to the feature amount types, and arbitrary feature amount types may be set and stored in the setting information storage unit 102.

Next, the search execution period table of FIG. 3B will be described with reference to FIG.
FIG. 4 is a diagram showing an example of the relationship between the search implementation period and the search non-execution period in the operation period of the air conditioning control device 100 according to the present embodiment. In FIG. 4, the horizontal axis is time.
In FIG. 4, the operation period is a period from the operation start time (time t11) to the operation end time (time t16) shown in FIG. 3 (A). The search non-execution period and the search execution period are in the operation period. The search implementation days and the search non-execution days shown in FIG. 3B are alternately repeated. In FIG. 4, the search non-execution period (time t11 to time t12) is started from the operation start time (time t11), and thereafter the search is not performed as the search execution period (time t12 to time t13, time t14 to time t15). The example in the case where an implementation period (time t13-time t14) is performed alternately is shown. In the present embodiment, by repeating the search non-execution period and the search execution period, it is possible to appropriately change the allowable range in the operation period, and it is possible to perform air conditioning control that achieves both comfort and energy saving.

  Here, the search is a search for an allowable range of the set temperature that the user of the air conditioner 200 can tolerate. The allowable range of the setting temperature acceptable to the user is, for example, a temperature range at which the user can tolerate cold in the case of heating, and a temperature range at which the user can tolerate the heat in the case of cooling. It is. In the case of heating, the setting temperature that is the most energy saving in the allowable range is the lowest lower limit temperature in the allowable range, and in the case of cooling, it is the highest upper temperature in the allowable range. In the present embodiment, the set temperature (upper limit temperature or lower limit temperature) that achieves the most energy saving in the allowable range is hereinafter referred to as “optimum set temperature”. The air conditioning control device 100 can realize energy saving in the air conditioner 200 by calculating the optimal set temperature as a control value for air conditioning control and outputting the calculated value to the air conditioner 200. The air conditioning control device 100 searches for whether the allowable range can be changed to the energy saving side in the search period. That is, in the search period, the air conditioning control device 100 performs control to change the set temperature. The air conditioning control device 100 performs control to lower the set temperature when the operation mode is heating, and controls to increase the set temperature when the operation mode is cooling. When changing the set temperature in this way, if the user feels uncomfortable, the user operates to change the set temperature. In the present embodiment, by obtaining such a history, the setting range that the user can tolerate and the static setting temperature that can realize energy saving are obtained in consideration of the influence of the outside air.

Next, the allowable range calculation time set in FIG. 3 (C) and the set temperature change time set in FIG. 3 (D) will be described using FIG.
FIG. 5 shows the time when the allowable range calculation unit 114 in the present embodiment calculates the allowable range, and the control value determination unit 115 calculates a control value and outputs a control value instructing change of the set temperature to the air conditioner 200. It is a figure which shows an example of time. In FIG. 5, the horizontal axis is time.

  In FIG. 5, the timing for calculating the allowable range is the operation period set in FIG. 3 (A), the search period set in FIG. 3 (B), and the allowable range calculation time set in FIG. 3 (C) It is determined based on The instruction unit 112 acquires these pieces of information stored in the setting information storage unit 102, determines whether or not it is the allowable range calculation time, and instructs the allowable range calculation unit to calculate the allowable range. The instruction unit 112 determines, for example, 7 am on the start date of the search execution period and 7 am on the start date of the search non-execution period as the allowable range calculation time. In the example shown in FIG. 5, the start date of the search non-execution period is the next day after the end date of the search execution period. Also, the start date of the search implementation period is the next day after the end date of the search non-execution period. In addition, the timing which calculates a tolerance | permissible_range is not limited to the timing shown in FIG. 5 grade | etc., For example, you may calculate only in the start date of a search implementation period.

  Next, details of the process performed by the dividing unit 113 will be described using FIGS. 6 and 7. FIG. 6 is a diagram showing an example of a calculation method of the preset temperature duration and the attribute performed by the division unit 113 in the present embodiment.

  FIG. 6A illustrates an example of setting value history information stored in the history information storage unit 101. The set value history information is recorded as a change in set temperature with the passage of time. In the example shown in FIG. 6A, the set temperature from t1 to t2 is 22 ° C., the set temperature from t2 to t3 is 21 ° C., and the set temperature from t3 to t4 is 22 ° C. t1 is the operation start time of the air conditioner 200. t4 is the operation stop time of the air conditioner 200. The set temperature continuation time is represented by how long each set temperature continues from the operation start time to the operation stop time of the air conditioner 200.

  6B and 6C show environment value history information stored in the history information storage unit 101. FIG. The environmental value history information is recorded as changes in environmental values over time. FIG. 6B shows changes in the outside temperature on the day of the setting value history information in FIG. 6A and the room temperature on the day. The solid line shows the change of the outside temperature on the day, and the broken line shows the change of the room temperature on the day. FIG. 6C shows changes in the previous day outside temperature and the previous day room temperature of the setting value history information in FIG. 6A. The solid line is the change in outside temperature one day ago, and the broken line is the change in room temperature one day ago.

  FIG. 6D is a relationship diagram of the setting temperature duration calculated based on the setting value history information of FIG. 6A, the value of the event, and the attribute. In the following, the set temperature duration and events will be described first. For example, when the set temperature is 22 ° C., the set temperature duration time is calculated as (t2−t1) and (t4−t3). Further, when the set temperature is 21 ° C., the set temperature continuation time is calculated as (t3−t2). The time before t1 when the air conditioner is not operating and the time after t4 are not included in the calculation of the set temperature duration. The dividing unit 113 associates the value of the event with the calculated set temperature duration.

Here, the event means a change of the set temperature by the user. When the user operates the input / display device 300 to change the set temperature, the division unit 113 sets the value of the event to 1. In other cases, the division unit 113 sets the value of the event to 0. For example, when the operation mode of the air conditioner 200 is heating and the user raises the set temperature, it can be estimated that the user can not accept the cold due to the current set value. When the operation mode of the air conditioner 200 is cooling and the user lowers the set temperature, it can be estimated that the user can not accept the heat. That is, the occurrence time of the event is the time when it is determined that the user can not tolerate the current setting value. In the present embodiment, the allowable range of the set temperature for energy saving is calculated. Therefore, for example, when the user raises the preset temperature by heating too much or raises the preset temperature by cooling too much in the cooling, the dividing unit 113 sets the value of the event to zero. Further, the dividing unit 113 sets the value of the event to 0 also when the operation of the air conditioner 200 is stopped by the manual operation by the user or in the automatic operation.
For example, FIG. 6B is an example in which the set temperature is raised from 21 ° C. to 22 ° C. by the user at time t3 in the heating mode. Therefore, the division unit 113 sets the value of the event corresponding to the set temperature continuation time t3 to t2 of 21 ° C. to one. Further, the division unit 113 sets all of the event values of the other set temperature durations to 0.
The time used by the division unit 113 for division is a time during which setting values continue from the start of operation of the air conditioning control apparatus 100 in a predetermined operation mode (heating and cooling) to division of history information related to setting values. .

Next, the attributes in FIG. 6D will be described.
In the example shown in FIG. 6 (D), "the outside temperature OT of the time ta on the day," the room temperature RT on the day ta "," the average outside temperature OTM of ts to te one day ago "," ts one day ago The room temperature average RTM of ~ te is the attribute.
The method of calculating these four attributes will be described in order. "The outside temperature OT of the time ta of the day is that the division unit 113 calculated the value of the time ta of the outside temperature acquired as environmental value history information of the same day as the time used in the calculation of the setting temperature duration" It is. In the example shown in FIG. 6D, it is indicated that the outside air temperature at the time ta on the same day as the times t1, t2, t3 and t4 is 4.0 ° C., and that value is given to each set temperature duration time Show that. The calculation of the setting temperature continuation time (t10 to t9) of another day indicates that the outside temperature at the time ta of the day t9 and the day 10 is 3.8.degree.
The dividing unit 113 also calculates “the room temperature RT at the time ta on the current day” in the same manner.

“One day before ts ~ te outside temperature average OTM” is the outside temperature from time ts obtained as environment value history information one day before the time used for calculation of the setting temperature duration time from outside temperature at time te It is an average value. The average value is calculated by the dividing unit 113. In the example shown in FIG. 6D, it is shown that the average value of the outside air temperature at time t1, t2, t3 and t4 from the time ts on the previous day is 7.8 ° C. It indicates that a value is given. Also, in the example shown in FIG. 6 (D), in the preset temperature continuation time (t10 to t9) of another day, the average value of the outside temperature from time ts of the day before that day is 6.4 ° C. Is shown.
The dividing unit 113 also calculates “room temperature average RTM of ts to te one day ago” in the same manner.
In addition, the division unit 113 also calculates the index of thermal sensation based on the acquired environmental value history information.

  The dividing unit 113 analyzes the survival time based on, for example, the set temperature duration shown in FIG. Here, the survival time analysis is one of methods for predicting the survival time of the observation target. For example, the observation target is a machine or the like, and the time (survival time) until failure (death) of the observation target is predicted. The failure or the like of the observation target is called an event in survival time analysis. The survival time is the time from the start of observation to the occurrence of an event. In the present embodiment, the observation start time and the observation end time in the survival time analysis are arbitrary. For example, the heating start date may be set as the observation start time, and the heating end date may be set as the observation end time. In the present embodiment, by setting the set temperature as an observation target and changing the set temperature as an event, the set temperature continuation time is set as the survival time of the set temperature. That is, in the relationship diagram of the preset temperature duration and the value of the event shown in FIG. 6B, the change of the preset temperature in which the value of the event is 1 is set as the event. Further, in the present embodiment, the set temperature change in which the value of the event is 0 is discontinued. Note that censoring means that the observation is censored on the way without an event occurring.

  In the survival time analysis of the present embodiment, the set temperature duration is represented by a survival function for each set temperature. The survival function S (t) is a function of the probability (survival rate) of the observed object at time t (t is a real number greater than 0). The survival function S (t) is represented by a ratio of the number of set temperature durations longer than time t to the number of all set temperature durations (sample size).

  The dividing unit 113 divides the duration for each set temperature according to the usage attribute designated in FIG. 3 (F). Below, an example of the division method is described. The dividing unit 113 rearranges the values of the use attribute in ascending order, and prepares a plurality of threshold values. The dividing unit 113 divides the set temperature duration to which the value of the attribute is given as shown in FIG. As a method of calculating the threshold value, for example, the number of threshold values may be 10, and the threshold value may be determined so as to equally divide from the minimum value to the maximum value of the attribute. The number of divisions and the range of attribute values are stored, for example, in the setting information storage unit 102.

  The dividing unit 113 applies the log rank test to data of the preset temperature duration divided into two for each threshold to calculate the p value. Here, the log rank test is a method of testing whether or not two survival time data are different in survival time analysis. In the log rank test, it can be expected that the two survival time data are different from each other as the p value is smaller. The dividing unit 113 sets a threshold in the case where the p value is minimum when the set temperature duration is divided by the plurality of thresholds described above as a final divided value.

  FIG. 7 is a diagram showing an example of a calculation method of dividing data of the preset temperature duration by OT which is the outside air temperature at time ta. In FIG. 7, the horizontal axis is time, and the vertical axis is the survival rate. FIG. 7A shows an example of the time change of the survival rate when the attribute is “the outside temperature OT of the time ta of the day, and the setting temperature is 22 ° C., and the survival function is Kaplan-Meier. An example modeled by the method is shown. FIG. 7B shows that the attribute is “outside temperature OT of time ta of the current day”, and Tb ° C. is selected as the final division value. Further, in FIG. 7B, a code g1 indicates a time change of the survival rate equal to or higher than the division value Tb when the set temperature is 22 ° C. and the usage attribute is “outside temperature OT of time ta of the day”. Further, a code g2 indicates a time change of the survival rate less than the division value Tb when the set temperature is 22 ° C. and the usage attribute is “outside temperature OT of time ta of the day”. FIG. 7B also shows that Tb ° C. is selected as the final division value.

The dividing method is not limited to that described above, and may be a method using p value of t test or the like. Further, instead of determining the division value based on the data as described above, the division temperature may be determined in advance, and the set temperature duration may be divided. When the division value is determined in advance, the value may be stored in the setting information storage unit 102.
Moreover, although the case of setting temperature 22 degreeC is demonstrated in FIG. 7, the division | segmentation of the continuation time of other setting temperature can be calculated similarly. Also, instead of determining the division value for each set temperature, a single division value may be determined for the duration of all the set temperatures.

  Further, although FIG. 7 shows an example of the division method using a single attribute, a plurality of attributes may be combined. As a combination method of a plurality of attributes, for example, there is a method using a Cox proportional hazard model. In survival time analysis, there is a function called an instantaneous mortality rate or hazard function, and the hazard function h (t) is given by the following equation (1) for the survival function S (t).

  The Cox proportional hazards model is obtained by modeling h (t) of equation (1) by the following equation (2).

  In equation (2), the function h0 (t) is called a baseline hazard function. Here, a1, a2, ..., an are estimated with z1, z2, ..., zn as attributes. The estimation is performed by, for example, a maximum likelihood estimation method. Here, a1 * z1 + a2 * z2 +... + An * zn after estimation is referred to as a score, and this score value is given to the set temperature duration. Similar to the data division of the setting temperature duration for the single attribute described above, a plurality of threshold values are prepared, the data is divided into two for each threshold value, and the threshold value for which the p value of the log rank test is minimum The final division value may be used. In order to use the score for division, the attribute in FIG. 3F may be used as the score. In this case, the division unit 113 divides the set temperature duration using this score.

It is not necessary to use all the attributes registered in FIG. 3E for the calculation of the score, and they may be combined as appropriate. The way of combination is stored in the setting information storage unit 102. Further, an attribute to be used for calculating the score may be selected by using an index of model selection such as AIC (Akaike Information Criterion).
Moreover, as a method of combining a plurality of attributes and setting it as a score, it is not limited to a Cox proportional hazards model, but logistic distribution etc. may be used.
Furthermore, the division unit 113 can also determine division values for each set temperature for division by score. In addition, the dividing unit 113 may not determine the division value for each set temperature, but may determine a single division value for the duration of all the set temperatures.
Note that although the division value may be different for each set temperature, FIGS. 8 to 14 described later show an example where the division value is the same for the continuation time of all the set temperatures.

  The dividing unit 113 outputs the set temperature duration divided by the attribute or the score to the allowable range calculating unit 114 as described above. Further, division section 113 gives division section for each set temperature to instruction section 112. The instruction unit 112 further outputs the division value for each set temperature to the control value determination unit 115.

Next, details of the process performed by the allowable range calculation unit 114 will be described using FIGS. 8 to 14.
As described above, the tolerance range calculation unit 114 obtains the feature amount, and obtains the identification boundary line for classifying into the region of the tolerance range and the region outside the tolerance range. Then, the allowable range calculation unit 114 determines whether the set temperature is within the allowable range based on the feature amount of the set temperature and the identification boundary line, and generates the set temperature table based on the determination result.

First, an example of the method of calculating the feature amount will be described.
FIG. 8 is a diagram illustrating an example of the method of calculating the feature amount according to the present embodiment. FIG. 8A is a graph in which the survival function of the set temperature is modeled by the Weibull distribution when the usage attribute is “outside temperature OT of time ta of the current day” and the division value is Tb ° C. In FIG. 8 (A), the horizontal axis is time, and the vertical axis is the survival rate. FIG. 8B shows the calculation result of calculation of scale parameter λ and shape parameter p described later based on the graph approximated in FIG. 8A.

  In FIG. 8 (A), the code g11 indicates that the set temperature is 22 ° C., and the “outside temperature OT of the time ta on the day” indicates the time change of the survival rate equal to or higher than the division value Tb. The code g12 indicates that the set temperature is 22 ° C., and the “outside air temperature OT of the time ta on the day” indicates a time change of the survival rate less than the division value Tb. The code g13 indicates that the set temperature is 21 ° C., and the “outside air temperature OT of the time ta on the day” indicates a time change of the survival rate equal to or higher than the division value Tb. The code g14 indicates that the set temperature is 21 ° C., and the “outside temperature OT of the time ta of the day” indicates a time change of the survival rate less than the division value Tb.

The allowable range calculation unit 114 acquires the feature amount type stored in the setting information storage unit 102 as shown in FIG. 3G and the use parameter of the identification boundary. FIG. 8 shows an example of calculating coefficient parameters of the Weibull distribution as the feature amount.
The allowable range calculation unit 114 analyzes the survival time based on the set temperature duration as shown in FIG. 6 (D). In the present embodiment, an example in which the survival function S (t) for each set temperature is modeled by a Weibull distribution will be described. The survival function S (t) is expressed by the following equation (3) using the scale parameter λ and the shape parameter p.

In FIG. 8 (A), the survival function at 22 ° C. where “the outside temperature OT at the time ta on the day is less than Tb ° C. (code g12) is 22 ° C. the“ outside temperature OT at the time ta on the day ”is Tb ° C. or more. The decrease with time t is large with respect to the survival function (symbol g11) of That is, when the temperature setting is set to 22 ° C. when “the outside temperature OT of the time ta of the day is less than Tb ° C., the temperature setting is set to 22 ° C. when the“ outside temperature OT of the time ta of the day ”is Tb ° C. or more. This indicates that the user has a high probability that the setting value is raised (an event is generated) as compared with the case of.
Similarly, the survival function of 21 ° C. where “the outside temperature OT of the time ta of the day is less than Tb ° C. (sign g14) is the survival function of 21 ° C. where the outside temperature OT of the time ta of the day is Tb ° C. or more The decrease with time t is large with respect to the code g13). That is, when the temperature setting is 21 ° C. when “the outside temperature OT of the time ta of the day is less than Tb ° C., the temperature setting is 21 ° C. when the“ outside temperature OT of the time ta of the day ”is Tb ° C. or more. This indicates that the user has a high probability that the setting value is raised (an event is generated) as compared with the case of. Furthermore, the survival function (code g14) at 21 ° C. where “the outside temperature OT at the time ta on the day is less than Tb ° C.” means the survival function at 22 ° C. “the outside temperature OT at the time ta on the day is less than Tb ° C. The decrease with time t is large with respect to g12).

  FIG. 8B shows the calculation result in which the allowable range calculation unit 114 calculates the scale parameter λ and the shape parameter p of Expression (3) based on the graph approximated in FIG. 8A. In the present embodiment, the scale parameter λ and the shape parameter p calculated by the allowable range calculation unit 114 are used as feature amounts at respective set temperatures. As shown in FIG. 8B, the allowable range calculation unit 114 calculates the scale parameter λ and the shape parameter p for divided temperatures Tb or more and less than Tb for each set temperature. For example, when the set temperature is 21 ° C., the scale parameter λ of Tb or more is 0.2, the shape parameter p is 1.3, the scale parameter λ of less than Tb is 0.25, and the shape parameter p is 1 .7.

The set temperature for calculating the feature amount may be all set temperatures acquired by the history information acquisition unit 111 or a part of the set temperatures. In addition, when there are a plurality of air conditioners 200, the feature amount may be calculated for each air conditioner 200. In addition, as the setting value history information used by the allowable range calculation unit 114 at the allowable range calculation time, even if all history information from the allowable range calculation time to the operation start time is used, the search start period start date is acceptable. The history information in the search non-execution period immediately before the range calculation time may be used, or the history information in the search implementation period immediately before the allowable range calculation time of the search non-execution period start date may be used.
Although FIG. 8 exemplifies a case where the survival function S (t) is modeled by the Weibull distribution, the distribution model is not limited to the Weibull distribution, and the feature parameter is the scale parameter λ of the Weibull distribution and the shape parameter It is not limited to what is calculated by p. For example, the average and the variance of the set temperature duration may be used as the feature amount. Further, for example, a maximum likelihood method or the like may be used as the method of calculating the feature amount.

Next, an example of how to obtain the identification boundary will be described.
FIG. 9 is a diagram showing an example of a plot of the scale parameter λ and the shape parameter p, which are feature quantities. In FIG. 9, the horizontal axis is the scale parameter λ, and the vertical axis is the shape parameter p. Circles are plotted values of feature quantities at each set temperature.
The coordinates of the feature amount can be classified into the area of the tolerance range and the area outside the tolerance range by the identification boundary line g21. The allowable range calculation unit 114 obtains the identification boundary line g21 from the use parameters (a, b) of the identification boundary in FIG. 3 (G).

  FIG. 9 shows an example in which the identification boundary is represented by a linear function (straight line) of inclination a and intercept b. The utilization parameter of the identification boundary is, for example, given in advance. The utilization parameter of the identification boundary is, for example, an allowable range using a machine learning method such as a linear support vector machine that classifies within the allowable range determined by the user and out of the allowable range in the history information of the previously set temperatures. The calculation unit 114 may calculate it. The determination by the user may be performed, for example, based on the length of the set temperature duration.

In FIG. 9, the region of the set temperature present on the upper left of the identification boundary is an allowable set temperature (acceptable range). Moreover, the area of the set temperature which exists to the lower right of the identification boundary is an unacceptable temperature (outside the allowable range). In the example shown in FIG. 9, for example, when the set temperature is 22 ° C. and the “outside temperature OT of the time ta of the day is Tb ° C. or higher and 23 ° C., it is an allowable range, and the set temperature is 22 ° C. When the outside temperature OT of time ta is less than Tb ° C. and 21 ° C., it is out of the allowable range.
As shown in FIG. 9, the allowable range calculation unit 114 determines whether the set temperature is within the allowable range based on the feature value of the set temperature and the identification boundary line. The allowable range calculation unit 114 generates a set temperature table described later with reference to FIG. 12 based on the determination result.

  Although the case where the allowable range calculation unit 114 determines whether the set temperature is within the allowable range is illustrated in the present embodiment, the method of determining the feature amount is not limited to this. For example, the allowable range calculation unit 114 determines the value of the logistic distribution obtained by substituting the feature quantity calculated for each set temperature into the explanatory variable of the logistic distribution using the logistic distribution in which coefficient parameters are calculated in advance. It may be used for

  FIGS. 10 and 11 are diagrams for explaining the method of calculating the feature amount based on the set temperature duration time when the score is used as the use attribute and the identification boundary of the feature amount. The allowable range calculation unit 114 generates the set temperature table also when the usage attribute is a score. FIG. 10A is a graph in which the survival function of the set temperature when the usage attribute is a score and the division value is Sb is modeled by a Weibull distribution. In FIG. 10 (A), the horizontal axis is time, and the vertical axis is the survival rate. FIG. 10B shows the calculation result of calculating the scale parameter λ and the shape parameter p based on the graph approximated in FIG.

In FIG. 10 (A), the code g31 indicates that the set temperature is 22 ° C., and the score shows a time change of the survival rate less than the division value Sb. The code g32 indicates that the set temperature is 22 ° C., and the score shows a time change of the survival rate equal to or higher than the division value Sb. The code g33 indicates that the set temperature is 21 ° C., and the score shows a time change of the survival rate less than the division value Sb. The code g34 indicates that the set temperature is 21 ° C., and the score shows a time change of the survival rate equal to or higher than the division value Sb.
The allowable range calculation unit 114 analyzes the survival time based on the set temperature duration.

  FIG. 10B shows the calculation result in which the allowable range calculation unit 114 calculates the scale parameter λ and the shape parameter p of Expression (3) based on the graph approximated in FIG. 10A. As shown in FIG. 10B, the allowable range calculation unit 114 calculates the scale parameter λ and the shape parameter p for divided values (scores) Sb or more and less than Sb for each set temperature. For example, when the set temperature is 21 ° C., the scale parameter λ below Sb is 0.19, the shape parameter p is 1.4, the scale parameter λ above Sb is 0.27, and the shape parameter p is 1 .8.

  In FIG. 11, the horizontal axis is the scale parameter λ, and the vertical axis is the shape parameter p. Circles are plotted values of feature quantities at each set temperature. The coordinates of the feature amount can be classified into the area of the tolerance range and the area outside the tolerance range by the identification boundary line g21, as in FIG.

FIG. 11 shows an example in which the identification boundary is represented by a linear function (straight line) of slope a and intercept b. In the example shown in FIG. 11, for example, the allowable range is when the set temperature is 22 ° C. and the score is less than Sb and 23 ° C., and when the set temperature is 22 ° C. and the score is Sb or more and 21 ° C. It is out of tolerance.
As illustrated in FIG. 11, the allowable range calculation unit 114 determines whether the set temperature is within the allowable range based on the feature value of the set temperature and the identification boundary line g21. The allowable range calculation unit 114 generates a set temperature table based on the determination result.

  Next, the set temperature table generated by the allowable range calculation unit 114 and stored by the allowable range storage unit 103 will be described with reference to FIGS. 12 and 13.

FIG. 12 is a diagram showing an example of a set temperature table in which the division value is Tb ° C. with “the outside temperature OT of the time ta of the current day” as a use attribute.
As shown in FIG. 12, the set temperature table includes items of an air conditioning type, a set temperature, a division range, and an allowable range determination.

The air conditioning or heating type item is set to the type of cooling or heating. In the example shown in FIG. 12, the setting temperature table in heating is shown. The division range is a range divided into two by the division value of the attribute determined by the division unit 113. In the example illustrated in FIG. 12, “the outside temperature OT of the time ta on the day” indicates a range of Tb or more and a range of less than Tb. The items of the set temperature and the determination of the allowable range are the determination results as to whether they are within the allowable range or outside the allowable range for each divided range.
In the example shown in FIG. 12, the allowable range judgment is out of the allowable range at the set temperature 22 ° C. where the set temperature is 20 ° C. and 21 ° C., and the “outside temperature OT of time ta of the day” is less than Tb ° C. It shows. Further, in the example shown in FIG. 12, it is indicated that the allowable range determination is the allowable range at the set temperature of 22 ° C. and the set temperature of 23 ° C. where “the outside temperature OT of time ta of the day is Tb ° C. or higher”. . If the set temperature is too high even during heating or the set temperature is too low even during cooling, it may be out of the allowable range.

  FIG. 13 is a diagram showing an example of a set temperature table when the usage attribute is a score. The example shown in FIG. 13 indicates that the allowable range determination is out of the allowable range at the set temperatures of 20 ° C. and 21 ° C., and at the set temperature of 22 ° C. whose score is Sb or more. Further, in the example illustrated in FIG. 13, it is indicated that the allowable range determination is the allowable range at the set temperature 22 ° C. and the set temperature 23 ° C. in which the score is less than Sb.

  12 and 13 show an example of the set temperature table in the case where the usage attribute is "outside temperature OT of time ta of the current day", but the same setting is applied when other usage attributes are used. A temperature table is determined.

  The control value determination unit 115 calculates, as a control value, an optimal set temperature among the set temperatures determined as the allowable range stored in the set temperature table, and outputs the control temperature to the air conditioner 200. The optimum set temperature is the set temperature that is the most energy saving among the set temperatures in the allowable range. The optimum setting temperature is the minimum setting temperature within the allowable range for heating. Further, the optimum set temperature is the maximum set temperature within the allowable range in cooling. Furthermore, the optimum setting temperature is the setting temperature that is acceptable for the user and is the most energy saving.

Next, an example of how to determine the optimum temperature will be described.
FIG. 14 is a diagram for explaining the calculation of the optimum set temperature in the present embodiment. The example shown in FIG. 14 is an example in which the optimum set temperature is calculated for the set temperature tables in FIGS. 12 and 13. 12 and 13 each show an example in which a single divided value is used at all set temperatures. In FIG. 14, a line indicated by reference sign g41 is a boundary line of the optimum set temperature.

Since control value determination unit 115 has the usage attribute "outside temperature OT of time ta on the day" and the division value is Tb ° C in FIG. 12, "outside temperature OT on time ta on the day" is Tb. It is determined that 22 ° C. is the optimum setting temperature in the range of ° C. or higher, and 23 ° C. is the optimum setting temperature in the range where “the outside temperature OT of time ta on the day” is less than Tb ° C.
In FIG. 13, the control value determination unit 115 determines that 23 ° C. is the optimum set temperature within the range where the score is Sb or more in FIG. 14 because the usage attribute is the score and the division value is Sb. It is determined that 22 ° C. is the optimum set temperature within the range of

Further, FIG. 14 also shows an example related to “the room temperature RT at the time ta of the day” which is not described in FIGS. 12 and 13. In this case, the control value determination unit 115 determines that 22 ° C. is the optimum set temperature in the range where “the room temperature RT at the time ta on the day” is Tc ° C. or more, and “the room temperature RT at the time ta on the day” is Tc ° C. Within the range of less than 23, it is determined that 23 ° C. is the optimum set temperature.
As for the other attributes, as in the case described above, the optimum set temperature may differ depending on the threshold regarding the attribute.

  Further, in the example shown in FIG. 14, the attribute is “outside temperature OT of time ta of the current day,” the division value is Tb ° C., the attribute is score, and the division value is Sb, and the attribute is Although the example is "room temperature RT of the time ta of the day" and the division value is Tb ° C, the present invention is not limited thereto. Other attributes may be used, and the division value may be either one of temperature and score.

  Note that the method of calculating the optimum set temperature is not limited to the above. The calculation method of the optimum set temperature may add, for example, that the set temperature is equal to or higher than a predetermined threshold or lower than a predetermined threshold from the set temperatures in the allowable range during the heating operation. In addition, the calculation method of the optimum set temperature may be, for example, conditions such as time, the number of users, the installation environment of the air conditioner, and the like.

Next, control of the control value determination unit 115 in the search execution period and the search non-execution period described in FIG. 3B and the like will be described.
FIG. 15 is a diagram showing an example of a control content table for setting control content of the control value determination unit 115 in the present embodiment. The control content table is stored in the setting information storage unit 102. The control value determination unit 115 acquires information of the control content table stored in the setting information storage unit 102 via the instruction unit 112. If the set temperature allowable range is not stored in the set temperature table, the control value determination unit 115 may use the preset temperature as the optimum temperature or carry out the control content described in the control content table. It does not have to be.

  In the example shown in FIG. 15, the control content table has items of period, operation mode of air conditioner, set temperature of air conditioner, and control content. The item of the period is set to be a search execution period or a search non-execution period. The entire period is a setting of a period including both a search execution period and a search non-execution period. The item of the operating mode of the air conditioner is set to heating or cooling. The set temperature of the air conditioner is set by comparing the set temperature obtained from the air conditioner 200 with the optimum temperature calculated by the control value determination unit 115. For example, the setting of being higher than the optimum temperature is the case where the set temperature is higher than the optimum temperature. As the control content item, the control content to be executed by the control value determination unit 115 is set when the conditions set in the items of the period, the operation mode of the air conditioner, and the set temperature of the air conditioner are met. That is, the items of the period, the operation mode of the air conditioner, and the set temperature of the air conditioner are the conditions for narrowing down when the control content is selected.

  The control value determination unit 115 narrows down the items of the period based on the information acquired via the instruction unit 112 whether the current time is a search execution period or a search non-execution period. For example, when the current time is a search implementation period, the control value determination unit 115 does not narrow down the control content, as the entire period and the search implementation period illustrated in FIG. 10 correspond. On the other hand, when the current time is a search non-execution period, the control value determination unit 115 narrows down the control content corresponding to all the periods illustrated in FIG. Similarly, the control value determination unit 115 narrows down the control content by acquiring the current operation mode of the air conditioner 200 and the set temperature.

First, in FIG. 15, the selection condition and control content of the first line indicated by reference numeral g51 will be described.
Since the “period” is the “full period”, the control value determination unit 115 selects either the search execution period or the search non-execution period.
Since the “operation mode of the air conditioner” is “heating”, the control value determination unit 115 selects the operation mode of the air conditioner 200 when the operation mode is heating.
Since the “set temperature of the air conditioner” is “higher than the optimum temperature”, the control value determination unit 115 determines that the current temperature of the air conditioner 200 is higher than the optimum temperature calculated from the set temperature table of the allowable range storage unit 103. Select when the set temperature of is high.
Since the “control content” is “change to the optimum temperature”, the control value determination unit 115 outputs the optimum temperature to the air conditioner 200 as a control value.

  When the set temperature of the air conditioner 200 is higher than the optimum temperature by the control under the selection condition of the first line indicated by the reference symbol g51, the set temperature can be changed to the optimum temperature in all periods to realize energy saving. If the user can not tolerate the set temperature changed to the optimum temperature, the user further changes the set temperature from the input / display device 300. The change of the set temperature is stored as an event in the history information storage unit 101, and is reflected in the calculation of the allowable range by the allowable range calculation unit 114 at the next allowable range calculation time.

Next, selection conditions and control contents of the second line indicated by reference numeral g52 in FIG. 15 will be described.
Since the “period” is the “full period”, the control value determination unit 115 selects either the search execution period or the search non-execution period.
Since the “operation mode of the air conditioner” is “heating”, the control value determination unit 115 selects the operation mode of the air conditioner 200 when the operation mode is heating.
Since the “set temperature of the air conditioner” is “lower than the optimum temperature”, the control value determination unit 115 determines that the current temperature of the air conditioner 200 is higher than the optimum temperature calculated from the set temperature table of the allowable range storage unit 103. Select when the set temperature of is low.
Since the “control content” is “do nothing”, the control value determination unit 115 does not output the control value to the air conditioner 200.

  If the set temperature of the air conditioner 200 is lower than the optimum temperature by control based on the selection condition of the second line indicated by symbol g52, the set value is not changed because it is already in the energy saving state. The set temperature lower than the optimum temperature set by the user is stored as an event in the history information storage unit 101, and is reflected in the calculation of the allowable range by the allowable range calculation unit 114 at the next allowable range calculation time.

Next, selection conditions and control contents of the third line indicated by reference numeral g53 in FIG. 15 will be described.
Since the “period” is the “search execution period”, the control value determination unit 115 selects the search execution period.
Since the “operation mode of the air conditioner” is “heating”, the control value determination unit 115 selects the operation mode of the air conditioner 200 when the operation mode is heating.
Since the “set temperature of the air conditioner” is “equal to the optimum temperature”, the control value determination unit 115 determines the optimum temperature calculated from the set temperature table of the allowable range storage unit 103 and the current temperature of the air conditioner 200. Select when the set temperature is equal.
Since the “control content” is “change to a temperature that is lower than the optimum temperature by T0 ° C.”, the control value determination unit 115 outputs a temperature that is lower than the optimum temperature by T0 ° C. to the air conditioner 200 as a control value.

  The control value determination unit 115 determines whether the set temperature (search temperature) lower than the optimum temperature by the control temperature of the air conditioner 200 is included in the allowable range by the control based on the selection condition of the third line indicated by the code g53. Search. For example, when the user does not raise the set temperature at the set temperature to the search temperature, it can be estimated that the search temperature is acceptable for the user. On the other hand, when the user raises the set temperature at the set temperature to the search temperature, it can be estimated that the search temperature is unacceptable for the user. In the present embodiment, by measuring the set temperature duration until the occurrence of an event, it is possible to calculate the user's acceptability at the search temperature. The operation (or no operation) of the user's set temperature with respect to the search temperature is stored as an event in the history information storage unit 101, and is reflected in the calculation of the allowable range by the allowable range calculation unit 114 at the next allowable range calculation time.

The value of T0 ° C. for setting the search temperature may be a predetermined fixed value or a variable value. For example, if the user has not permitted a change in T0 ° C. in the search execution period last time, the search temperature may be changed in a temperature change smaller than T0 ° C.
Moreover, although control by the selection condition of 3rd line shown to the code | symbol g53 demonstrated the case where "set temperature of an air conditioner" was "equal to optimal temperature", "set temperature of an air conditioner", for example, Even in the case of "higher than the optimum temperature", the control content of the third line indicated by reference numeral g53 may be executed.
Although FIG. 15 illustrates the case where the operation mode is heating, the search temperature may be set to search for energy saving even when the operation mode is cooling.

  Next, the air conditioning control arithmetic processing according to the present embodiment will be described using FIGS. 16 to 19. FIGS. 16-19 is a figure of the flowchart which shows an example of the calculation processing for air-conditioning control in this embodiment. In the processes shown in the flowcharts of FIGS. 16 to 19, the air conditioning control device 100 described later with reference to FIG. 24 is a processor, and the functional units of the air conditioning control device 100 are executed by software. It will be described that the control device 100 executes.

First, the process of FIG. 16 will be described.
The operation of the flowchart in FIG. 16 is started when the air conditioning control device 100 is powered on or the like.
(Step S101) The air conditioning control device 100 acquires the setting information stored in the setting information storage unit 102 as described with reference to FIGS. 3 (A) to 3 (G). The setting information stored in the setting information storage unit 102 is, for example, information acquired from the operation period table, the search execution period table, the allowable range calculation time table, the set temperature change time table, and the identification boundary table.

  (Step S102) The air conditioning control device 100 determines whether it is within the operation period. Note that the air conditioning control device 100 determines whether or not it is within the operation period based on the current time and the setting information set in the operation period table. If the air conditioning control device 100 determines that it is not within the operation period (step S102; NO), the air conditioning control device 100 ends the process of the flowchart of FIG. If the air conditioning control device 100 determines that it is within the operation period (step S102; YES), it proceeds to the process of step S103.

  (Step S103) The air conditioning control device 100 determines whether or not it is within the search implementation period. The air conditioning control device 100 determines whether or not it is within the search implementation period based on the current time and the setting information set in the search implementation period table. If the air conditioning control device 100 determines that it is not within the search implementation period (step S103; NO), it proceeds to the process of step S104. If the air conditioning control device 100 determines that it is within the search implementation period (step S103; YES), it proceeds to the process of step S105.

  (Step S104) The air conditioning control device 100 executes a search non-execution period process. The details of the process of step S104 will be described later with reference to FIG. After the processing, the air conditioning control device 100 proceeds to the processing of step S106.

  (Step S105) The air conditioning control device 100 executes a search execution period process. The details of the process of step S105 will be described later with reference to FIGS. 18 and 19. After the processing, the air conditioning control device 100 proceeds to the processing of step S106.

  (Step S106) The air conditioning control device 100 determines whether the standby time has elapsed. Note that the air conditioning control device 100 determines whether the standby time has elapsed, for example, based on the elapse of the standby time which is preset in the setting information storage unit 102 and adjusts the operation interval of the air conditioning control device 100. The standby time may be determined by starting the timer or the like after the process of step S104 or the process of step S105 is performed, and the timer is up. When determining that the standby time has not elapsed (step S106; NO), the air conditioning control device 100 repeatedly executes the process of step S106 and waits for the standby time to elapse. If the air conditioning control device 100 determines that the standby time has elapsed (step S106; YES), it returns to the process of step S102 and repeats the process of steps S102 to S106.

Next, the search non-execution period process of step S104 of FIG. 16 will be described using FIG.
(Step S201) The air conditioning control device 100 determines whether it is the control execution timing. The air conditioning control device 100 determines, for example, whether or not the control execution timing is reached based on the current time and the set temperature change time set in the set temperature change time table. If it is determined that the control execution timing is not reached (step S201; NO), the air conditioning control device 100 ends the processing of the flowchart shown in FIG. When it is determined that the control execution timing is reached (step S201; YES), the air conditioning control device 100 proceeds to the process of step S202.

  (Step S202) The air conditioning control device 100 executes the control content in the search non-execution period. Here, the control content in the search non-execution period is the process of narrowing down the control content when the item of “period” is “all period” described in FIG. More specifically, the control value determination unit 115 acquires information of the control content table via the instruction unit 112. After the processing, the air conditioning control device 100 proceeds to the processing of step S203.

  (Step S203) The air conditioning control device 100 calculates an attribute. More specifically, the control value determination unit 115 acquires the use attribute and its division value from the division unit 113 via the instruction unit 112. Furthermore, the control value determination unit 115 calculates the value of the usage attribute after acquiring the history information for calculating the value of the usage attribute of the day for which the control content is set from the history information storage unit 101. After the processing, the air conditioning control device 100 proceeds to the processing of step S204.

  (Step S204) The air conditioning control device 100 determines an optimal set temperature. More specifically, the control value determination unit 115 acquires the set temperature table stored in the allowable range storage unit 103, and saves energy among the set temperatures for which the allowable range determination is the allowable range in the set temperature table. The set temperature is obtained as the optimum set temperature. Further, the control value determination unit 115 compares the value of the use attribute of the day for which the control content is set and the division value, and determines the optimum temperature for the day for which the control content is set. After the processing, the air conditioning control device 100 proceeds to the processing of step S205.

  (Step S205) The air conditioning control device 100 acquires the operation mode of the air conditioner 200 and the current set temperature. More specifically, the control value determination unit 115 acquires the operation mode and the current set temperature from the air conditioner 200. After the processing, the air conditioning control device 100 proceeds to the processing of step S206.

  (Step S206) The air conditioning control device 100 calculates a control value. More specifically, the control value determination unit 115 uses the information in the control content table, the optimum set temperature determined in the process of step S205, and the operation mode and the current set temperature of the air conditioner 200 acquired in step S206. Based on the above, the control value is calculated according to the control content described in FIG. After the processing, the air conditioning control device 100 proceeds to the processing of step S207.

  (Step S207) The air conditioning control device 100 outputs the control value to the air conditioner 200. More specifically, the control value determining unit 115 outputs the control value calculated in the process of step S205 to the air conditioner 200. The air conditioner 200 that has acquired the control value changes the set value based on the control value. After executing the process of step S207, the air conditioning control device 100 ends the process of the flowchart of FIG.

Next, the search execution period process of step S105 of FIG. 16 will be described using FIG.
(Step S301) The air conditioning control device 100 determines whether it is the allowable range calculation time. The air conditioning control device 100 determines whether the allowable range calculation time is reached based on the current time and the setting information set in the allowable range calculation time table. If the air conditioning control device 100 determines that it is the allowable range calculation time (step S301; YES), it proceeds to the process of step S302. If the air conditioning control device 100 determines that it is not the allowable range calculation time (step S301; NO), it proceeds to the process of step S306.

  (Step S302) The air conditioning control device 100 acquires setting value history information and environment value history information. More specifically, the dividing unit 113 acquires setting value history information and environment value history information stored in the history information storage unit 101 described with reference to FIG. After the processing, the air conditioning control device 100 proceeds to the processing of step S303.

  (Step S303) The air conditioning control device 100 divides the setting value history information by the division value. More specifically, the dividing unit 113 calculates the value of the usage attribute from the setting value history information and the environment value history information acquired in step S302 to determine the division value. Further, the division unit 113 divides the setting value history information according to the determined division value. After the processing, the air conditioning control device 100 proceeds to the processing of step S304.

  (Step S304) The air conditioning control device 100 calculates an allowable range. More specifically, the allowable range calculation unit 114 calculates the set temperature continuation time described in FIG. 6D based on the set value history information divided by the division value of the use attribute in step S303, and FIG. Alternatively, after the survival function of the set temperature described in FIG. 10A is modeled by the Weibull distribution, the feature amount described in FIG. 8B or FIG. 10B is calculated. The allowable range calculation unit 114 calculates the allowable range described in FIG. 9 or 11 based on the calculated feature amount and a predetermined identification boundary line. After the processing, the air conditioning control device 100 proceeds to the processing of step S305.

  (Step S305) The air conditioning control device 100 stores the allowable range. More specifically, the allowable range calculation unit 114 generates the set temperature table described with reference to FIGS. 12 and 13 based on the allowable range calculated in the process of step S304, and causes the allowable range storage unit 103 to store the table. After the processing, the air conditioning control device 100 proceeds to the processing of step S306.

  (Step S306) The air conditioning control device 100 executes control processing. After executing the process of step S306, the air conditioning control device 100 ends the process of the flowchart of FIG.

Next, the search execution period process of step S306 in FIG. 18 will be described using FIG.
(Step S401) The air conditioning control device 100 determines whether it is the control implementation timing. The air conditioning control device 100 determines whether the control execution timing is reached based on the current time and the set temperature change time set in the set temperature change time table. When determining that the control execution timing is not reached (step S401; NO), the air conditioning control device 100 ends the processing of the flowchart in FIG. When it is determined that the control execution timing is reached (step S401; YES), the air conditioning control device 100 proceeds to the process of step S402.

  (Step S402) The air-conditioning control apparatus 100 executes the control content in the search implementation period. Here, the control content in the search implementation period is a process of narrowing down the control content when the item of “period” described in FIG. 15 is the “search implementation period”. More specifically, the control value determination unit 115 acquires information of the control content table via the instruction unit 112. After the processing, the air conditioning control device 100 proceeds to the processing of step S403.

  (Step S403) The air conditioning control device 100 calculates an attribute. More specifically, the control value determination unit 115 acquires the use attribute and its division value from the division unit 113 via the instruction unit 112. Furthermore, the control value determination unit 115 obtains the value of the usage attribute after acquiring the history information for calculating the value of the usage attribute of the day for which the control content is set from the history information storage unit 101. After the processing, the air conditioning control device 100 proceeds to the processing of step S404.

  (Step S404) The air conditioning control device 100 determines the optimum set temperature. More specifically, the control value determination unit 115 acquires the set temperature table stored in the allowable range storage unit 103, and saves energy among the set temperatures for which the allowable range determination is the allowable range in the set temperature table. The set temperature is obtained as the optimum set temperature. Further, the control value determination unit 115 compares the value of the use attribute of the day for which the control content is set and the division value, and determines the optimum temperature for the day for which the control content is set. After the processing, the air conditioning control device 100 proceeds to the processing of step S405.

  (Step S405) The air conditioning control device 100 acquires the operation mode of the air conditioner 200 and the current set temperature. More specifically, the control value determination unit 115 acquires the operation mode and the current set temperature from the air conditioner 200. After the processing, the air conditioning control device 100 proceeds to the processing of step S406.

  (Step S406) The air conditioning control device 100 calculates a control value. More specifically, the control value determination unit 115 determines the information in the control content table, the optimum set temperature determined in the process of step S404, and the operation mode and the current set temperature of the air conditioner 200 acquired in step S405. Based on the above, the control value is calculated according to the control content described in FIG. After the processing, the air conditioning control device 100 proceeds to the processing of step S407.

  (Step S407) The air conditioning control device 100 outputs the control value to the air conditioner 200. More specifically, control value determination unit 115 outputs the control value calculated in the process of step S406 to air conditioner 200. The air conditioner 200 that has acquired the control value changes the set value based on the control value. After executing the process of step S407, the air conditioning control device 100 ends the process of the flowchart of FIG.

As described above, according to the present embodiment, it is possible to achieve both the allowance of the setting value and the energy saving, while considering the influence of the environment on the history information acquisition unit and the setting value. Note that the advisability of the setting value is whether or not the user can accept it.
Further, according to the present embodiment, since the environmental value is acquired from the environmental value acquisition device 400 and used, the influence of the space targeted by the air conditioner 200 and the external environment can be reduced.

Second Embodiment
Next, an example in which the detection result of the user in the detection unit 201 of FIG. 1 is reflected in the calculation of the allowable range and the calculation of the control value will be described with reference to FIGS. The configuration of the air conditioning control system 1 is the same as that shown in FIG.

  FIG. 20 is a view showing an example of the detection result of the user in the detection unit 201 in the present embodiment. The detection result of the user is stored in the history information storage unit 101, as in the setting value history information described with reference to FIG. Further, the control value determination unit 115 acquires the detection result of the user, and stores the detection result in the history information storage unit 101. As shown in FIG. 20, the detection result of the user includes the detected time and the detection result (reaction result). The history information storage unit 101 gives the time when the reaction result is obtained from the air conditioner 200, based on the time output by the clock unit 116. In the reaction result, 1 indicates that the user is detected, and 0 indicates that the user is not detected.

  FIG. 21 is a diagram showing another example of the method of calculating the set temperature duration performed by the dividing unit 113 described with reference to FIG. FIG. 21A shows the setting value history information stored in the history information storage unit 101 as in FIG. 6A. FIG. 21B shows the detection history of the detection result of the user. Further, FIG. 21C is a relationship diagram of the setting temperature duration and the value of the event which are calculated based on the setting value history information and the detection history of FIGS. 21A and 21B. Unlike FIG. 6D, the value of the attribute is not shown in FIG. 21C, but it is assumed that the value of the attribute is actually calculated.

  As shown in FIG. 21, in the modification, the set temperature duration is calculated only in the period in which the user is detected. When the user is absent, it may not be appropriate to evaluate the set temperature duration as the set temperature is not changed by the user. In FIG. 21C, the set temperature continuation time is determined as (t1'-t1) and (t4-t2 ') at 22C. The value of the event during the period when the user is detected is the same as in the first embodiment. On the other hand, when the user is not detected, the value of the state (event) is set to 0. Therefore, the value of the event at the set temperature duration (t1'-t1) is 0, and the value of the event at the set temperature duration (t4-t2 ') is 1. From the above, the allowable range calculation unit 114 can calculate the allowable range in consideration of the detection result of the user.

FIG. 22 is a diagram showing another example of the control content table in the present embodiment.
FIG. 22 is based on the detection result of the user by the detection unit 201 in the control contents described in FIG. In FIG. 22, in the search execution period, control content is shown in which the search temperature is output as a control value only when the user is detected. When the user is absent, the user does not change the set temperature, so the user's acceptability at the search temperature can not be judged correctly. In FIG. 22, by setting the detection of the user in the control content in the search execution period as a condition, it is possible to search for a more accurate tolerance range.

For example, the selection condition and control content of the third line indicated by reference numeral g61 in FIG. 22 will be described.
Since the “period” is the “search execution period”, the control value determination unit 115 selects the search execution period.
Since the “operation mode of the air conditioner” is “heating”, the control value determination unit 115 selects the operation mode of the air conditioner 200 when the operation mode is heating.
Since the “set temperature of the air conditioner” is “equal to the optimum temperature”, the control value determination unit 115 determines the optimum temperature calculated from the set temperature table of the allowable range storage unit 103 and the current temperature of the air conditioner 200. Select when the set temperature is equal.
Since the “detection result of the detection unit” is “present (present)” and the “control content” is “change to a temperature lower than the optimum temperature by T0 ° C.”, the control value determination unit 115 In contrast, a temperature that is lower than the optimum temperature by T0 ° C. is output as a control value.

  The control value determination unit 115 determines that the setting temperature of the air conditioner 200 is lower than the optimum temperature by T0 ° C. (search It is searched whether the temperature is included in the allowable range. For example, when the user does not raise the set temperature at the set temperature to the search temperature, it can be estimated that the search temperature is acceptable for the user. On the other hand, when the user raises the set temperature at the set temperature to the search temperature, it can be estimated that the search temperature is unacceptable for the user. In the present embodiment, by measuring the set temperature duration until the occurrence of an event, it is possible to calculate the user's acceptability at the search temperature. Also in this embodiment, the operation (or no operation) of the user's set temperature with respect to the search temperature is stored as an event in the history information storage unit 101, and the allowable range calculation unit 114 at the next allowable range calculation time Reflected in the calculation.

  As described above, according to the present embodiment, since control can be performed according to the presence or absence of the user, it is possible to perform operation that achieves more energy saving.

Although the configuration of the air conditioning control system 1 has been described using FIG. 1 in the first embodiment and the second embodiment, the configuration and arrangement of the air conditioning control system 1 are not limited to this.
An arrangement example and a configuration example of the air conditioning control device 100 in the air conditioning control system will be described with reference to FIG. FIG. 23 is a view showing an arrangement example and a configuration example of the air conditioning control system 1A according to the present embodiment. Note that the example shown in FIG. 23 is also an example provided with three environment value acquisition devices 400 (environment value acquisition devices 401 to 403).

  In the example shown in FIG. 23, the building air conditioning control system 500 is disposed in the office 501 and the management room 502 of the office building. An air conditioner 200, an input / display device 300, and a local controller 210 are disposed in the work room 501. A building energy management system (BEMS) server 150 is disposed in the management room 502. The user is assumed to be in the office room 501. The environmental value acquisition device 401 is installed in the office 501.

  The input / display device 300 is, for example, a remote controller installed in the office 501. The input / display device 300 may be a website, a smartphone application, or the like that allows the user to change the set temperature of the air conditioner 200.

The BEMS server 150 is a server that performs management of power consumption in a building, power saving control, and the like.
