Description

The present invention is the air conditioning management apparatus, an air conditioning management method, program, and a air-conditioning system.

  In the operation of the air conditioner, when the windows and doors in the air-conditioned space are opened, most of the air that has been warmed (cooled) by the air conditioner escapes. In such a situation, an inefficient useless operation in which the output of the air conditioner must be increased or operated for a long time occurs, which hinders power saving.

  Patent Document 1 discloses a monitoring device for an air conditioning conditioner for preventing such a wasteful operation. This monitoring device calculates a moving average of the opening degree of the air device expansion valve, and if the moving average exceeds a predetermined threshold for a certain period of time, it is determined that the air conditioner is operating wastefully, and the administrator Notification to.

  By the way, the environment (the number and size of windows and doors) of the space where the air conditioner is installed varies. Therefore, in the monitoring apparatus described in Patent Document 1, the threshold value needs to be set to an appropriate value according to the environment in which the air conditioner is installed. In this regard, the monitoring device described in Patent Document 1 automatically changes the threshold value to an appropriate threshold value by changing the threshold value based on the tendency of temperature change within a day, the outside air temperature, or the history of monitoring parameters for a predetermined number of days in the past. Set to.

<< first embodiment >>
An air conditioning management device 1 according to a first embodiment of the present invention will be described. As shown in FIG. 1, the air conditioning management device 1 is connected to an air conditioner 2 installed in an air conditioning target area and a sensor 3 that measures temperature and humidity in the air conditioning target area. The air conditioning management device 1 determines the operation control of the air conditioner 2 and the wasteful operation based on the current operation state of the air conditioner 2 and the measured value of the sensor 3. The air conditioning management device 1 physically includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a readable / writable semiconductor memory such as a hard disk drive or a flash memory, a communication interface, and the like. Computer.

  As shown in FIG. 2, the air conditioning management device 1 functionally includes an operation data acquisition unit 101, a trigger detection unit 102, a determination data generation unit 103, a waste operation determination unit 104, and a waste operation notification unit. 105, an evaluation input unit 106, a threshold adjustment unit 107, an operation data storage unit 108, a threshold storage unit 109, and a determination result storage unit 110. The configuration for controlling the operation of the air conditioner 2 is not shown because it is not the main configuration of the present invention.

  The operation data acquisition unit 101 has information indicating an operation state from the air conditioner 2 and a measured value measured by the sensor 3 (for example, temperature (room temperature) in the air-conditioning target area) at predetermined time intervals (for example, every 5 minutes). And get. Then, the driving data acquisition unit 101 stores driving data in which the acquired information and current date / time information are associated with each other in the driving data storage unit 108.

  The trigger detection unit 102 monitors the operation data stored in the operation data storage unit 108 and detects a trigger for starting a process for determining useless operation. In the present embodiment, when the cooling operation of the air conditioner 2 is started from the stop state (power OFF state) and when the steady state in which the room temperature can be kept constant by the cooling operation has occurred, the trigger described above is used. Detect as. In the following description, the “cooling operation start” trigger is used when the cooling operation is started from the power-off state, and the “cooling steady” trigger is used when a steady state in which the room temperature can be kept constant by the cooling operation occurs. Called.

  When the trigger detection unit 102 detects any of the above-described triggers, the determination data generation unit 103 acquires operation data for a predetermined time from the trigger detection time from the operation data storage unit 108. Then, the determination data generation unit 103 generates data for useless operation determination from the acquired operation data.

  The waste driving determination unit 104 determines whether or not there is a waste driving by comparing the waste driving determination data generated by the determination data generation unit 103 with the threshold data stored in the threshold storage unit 109, and the determination result Is stored in the determination result storage unit 110.

  When the wasteful driving notification unit 105 determines that the wasteful driving determination unit 104 is performing a wasteful driving, the wasteful driving notification unit 105 notifies the user of that fact in a predetermined manner. For example, the waste driving notification unit 105 includes an LED lamp and a speaker, and notifies the user of the occurrence of the waste driving by turning on the LED lamp or outputting sound from the speaker.

  The evaluation input unit 106 includes, for example, a predetermined button, and receives a result of evaluating whether or not wasteful driving actually occurs from the user. For example, when the predetermined button provided in the evaluation input unit 106 is configured with a “Yes” button and a “No” button, the user can generate a “Yes” button if a wasteful operation actually occurs. If there is not, the evaluation result of the wasteful operation can be input by pressing the “No” button. The evaluation input unit 106 outputs an evaluation result input by a user's button operation or the like to the threshold adjustment unit 107.

  The threshold adjustment unit 107 adjusts a threshold for determining whether or not there is a waste driving based on the evaluation result input from the evaluation input unit 106 and the past determination result stored in the determination result storage unit 110.

  As shown in FIG. 3, the operation data storage unit 108 stores the operation data acquired by the operation data acquisition unit 101 every predetermined time (in this example, every 5 minutes). In the example of FIG. 3, the operation data is data in which “date and time”, “operation mode”, “set temperature”, and “room temperature” are associated with each other. The “operation mode” and “set temperature” are information acquired from the controller of the air conditioner 2. “Room temperature” is the temperature (room temperature) of the air-conditioning target area measured by the sensor 3. Further, the “operation mode” is information indicating in what mode the air conditioner 2 is operated. For example, “cooling”, “heating”, “dehumidification”, “fan”, “power OFF” Etc.

  Returning to FIG. 2, the determination result storage unit 110 stores a result of determining whether or not there is a waste operation by the waste operation determination unit 104. Specifically, in the determination result storage unit 110, information indicating the trigger, information indicating the determination result of the wasteful operation determined when the trigger is detected, and determination data used for the determination are associated with each other. Judgment result data is stored. In the present embodiment, the rate of temperature change after 5 minutes, 10 minutes, and 15 minutes after the trigger detection time is used as determination data. In the present embodiment, the ratio of the room temperature change from the trigger detection time to the target time with respect to the difference between the room temperature and the set temperature when the air conditioner 2 is started is calculated as the temperature change rate at the target time.

Here, the temperature change rate will be described with a specific example. FIG. 4 is a diagram showing the relationship between the temperature (room temperature) of the air-conditioning target area where the air conditioner 2 is arranged and the time. At room temperature at time t _a is T _a, "cooling operation start" trigger with the air conditioner 2 to the time t _a is started is detected. Further, the room temperature reaches the set temperature T _c at time t _c . Also, room temperature at time _{t b} after the elapse of 15 minutes from the time _{t a} is _{T b.} In this case, the temperature change rate of the time t _b may be calculated from the following formula.
(Temperature change rate at time t _b ) = (T _b −T _a ) / | T _a −T _c |

Here, an example of the determination result data is shown in FIG.
FIG. 5A shows determination result data indicating a determination result of the wasteful operation determination performed when the “cooling operation start” trigger is detected. From this figure, the temperature change rates after 5 minutes, 10 minutes, and 15 minutes from the trigger detection time are “−30 percent”, “−50 percent”, and “−70 percent”, respectively. From the rate of change, it can be seen that it is determined that the operation is not wasteful (no wasteful operation).

  FIG. 5B shows determination result data indicating the determination result of the wasteful operation determination performed when the “cooling steady state” trigger is detected. From this figure, the temperature change rates at 5 minutes, 10 minutes, and 15 minutes after the trigger detection time are “0 percent”, “−10 percent”, and “0 percent”, respectively. From this, it can be seen that it was determined that there was no useless operation.

  Returning to FIG. 2, the threshold storage unit 109 stores a threshold for useless driving determination. Specifically, the threshold storage unit 109 stores information indicating a trigger and threshold data for determining wasteful driving when the trigger is detected.

Here, an example of threshold data is shown in FIG.
The threshold data shown in FIG. 6A indicates threshold data used in the determination of wasteful operation when the “cooling operation start” trigger is detected. From this figure, the absolute value of the temperature change rate after 5 minutes from the “cooling operation start” trigger detection time is “20 percent or more”, the temperature change rate after 10 minutes is “30 percent or more”, and 15 minutes. It can be seen that when the subsequent temperature change rate is “40% or more”, it is determined that there is no useless operation.

  Further, the threshold data shown in FIG. 6B shows threshold data used in the determination of wasteful operation when the “cooling steady” trigger is detected. From this figure, the absolute value of the temperature change rate 5 minutes after the “cooling steady” trigger detection time is “10 percent or less”, the temperature change rate after 10 minutes is “10 percent or less”, and 15 minutes later. When the temperature change rate is “30% or less”, it is understood that there is no wasteful operation.

  Then, the process implemented with the air-conditioning management apparatus 1 is demonstrated to the case where the air-conditioner 2 performs air_conditionaing | cooling operation as an example.

(Initial operation processing)
Immediately after the air conditioning management device 1 is installed, the threshold value storage unit 109 does not store a threshold value for determining whether or not there is a waste operation. Therefore, the air conditioning management device 1 performs an initial operation process and sets a temporary threshold value. Details of the initial operation processing will be described with reference to the flowchart of FIG.

  The initial operation process is started, for example, when the air conditioning management device 1 is activated in a state where the threshold value (threshold value data) is not stored in the threshold value storage unit 109. In parallel with the initial operation process, the operation data acquisition unit 101 periodically acquires operation data and stores it in the operation data storage unit 108.

  When the initial operation process is started, first, the trigger detection unit 102 monitors the operation data stored in the operation data storage unit 108 to determine whether or not a trigger for starting the waste operation determination is detected. (Step S101).

  When a trigger is detected (step S101; Yes), the determination data generation unit 103 waits from the time when the trigger is detected until operation data used for determination is accumulated (stored) in the operation data storage unit 108. (Step S102). In this embodiment, it waits until each operation data after 5 minutes, 10 minutes, and 15 minutes are memorize | stored.

  When the operation data used for the determination is stored, the determination data generation unit 103 generates (calculates) waste operation determination data (temperature change rate) from the contents of the operation data (step S103).

  Subsequently, the waste driving determination unit 104 includes information indicating the trigger detected in step S101 and data for waste driving determination generated in step S103 (temperature change after the lapse of 5 minutes, 10 minutes, and 15 minutes from the trigger detection time point). The determination result data in which the rate) is associated with the information indicating no waste driving is stored in the determination result storage unit 110 (step S104). In the initial operation process, since the threshold value for determining the wasteful operation is not stored in the threshold value storage unit 109, the wasteful operation determining unit 104 does not perform the wasteful operation determination process, and the determination result data indicates that there is always no wasteful operation. Shall be stored.

  Subsequently, the threshold adjustment unit 107 generates a temporary threshold (threshold data) for determining useless driving and stores it in the threshold storage unit 109 (step S105).

  For example, the threshold adjustment unit 107 uses the absolute value of the rate of change in temperature after the lapse of 5 minutes, 10 minutes, and 15 minutes acquired in step S103 as the threshold for useless operation determination used at the time of detecting the “cooling operation start” trigger. The values obtained by subtracting 10 percentage points, 20 percentage points, and 30 percentage points may be stored in the threshold value storage unit 109 as threshold values after 5 minutes, 10 minutes, and 15 minutes used in the determination at the time of trigger detection. Therefore, the threshold data shown in FIG. 6A is created from the determination result data shown in FIG.

  In addition, for example, the threshold adjustment unit 107 uses the temperature change rate after the elapse of 5 minutes, 10 minutes, and 15 minutes acquired in step S103 as the threshold for useless operation determination used when the “cooling steady state” trigger is detected. What is necessary is just to memorize | store in the threshold value memory | storage part 109 as a threshold value after 5 minutes, 10 minutes, and 15-minute progress which are used by the determination at the time of the said trigger detection, and a 10-percent point, 20-percent point, and 30-percent point big value. Therefore, the threshold data shown in FIG. 6B is created from the determination result data shown in FIG.

  Subsequently, the threshold adjustment unit 107 determines whether or not an end condition is satisfied (step S106). For example, the threshold adjustment unit 107 may determine that the end condition is satisfied when thresholds corresponding to both the “cooling operation start” trigger and the “cooling steady” trigger can be set.

  If the end condition is not satisfied (step S106; No), the process returns to step S101. If the end condition is satisfied (step S106; Yes), the initial operation process ends.

  Next, the initial operation process will be described with a specific example. For example, assuming that operation data is stored in the operation data storage unit 108 as illustrated in FIG. 3, a case where a “cooling operation start” trigger is detected at 12:00 on August 1, 2011 is considered. In this case, as the data for useless operation determination, the temperature is determined from the operation data at 12: 5, 12:10, and 12:15, which is 5 minutes, 10 minutes, and 15 minutes after the trigger detection. The rate of change is calculated. The temperature changes from the trigger detection time (12 o'clock) at 12: 5, 12:10, and 12:15 are −3 ° C., −5 ° C., and −7 ° C. Further, the difference between the set temperature when the air conditioner 2 is started (12 o'clock) and the room temperature is 10 ° C. Accordingly, the temperature change rates at 12: 5, 12:10, and 12:15 are “−30%”, “−50%”, and “−70%”. Further, since it is an initial operation process, it is always determined that there is no useless operation. Therefore, determination result data shown in FIG. 5A is created. Further, since a value obtained by adding a predetermined value from the calculated temperature change rate becomes a threshold value, the threshold value data shown in FIG. 6A is finally created from this determination result data.

  Consider a case where a “cooling steady state” trigger is detected at 13:00 on August 1, 2011. In this case, as the data for useless operation determination, the temperature is determined from each operation data at 13: 5, 13:10, 13:15, which is 5 minutes, 10 minutes, and 15 minutes after the trigger detection. The rate of change is calculated. The temperature changes from the trigger detection time (13 o'clock) at 13: 5, 13:10, and 13:15 are 0 ° C., −1 ° C., and 0 ° C. Further, the difference between the set temperature when the air conditioner 2 is started (12 o'clock) and the room temperature is 10 ° C. Therefore, the temperature change rates at 13: 5, 13:10, and 13:15 are “0%”, “−10%”, and “0%”. Further, since it is an initial operation process, it is always determined that there is no useless operation. Therefore, determination result data shown in FIG. 5B is created. Further, since a value obtained by adding a predetermined value from the calculated temperature change rate becomes a threshold value, the threshold value data shown in FIG. 6B is finally created from this determination result data.

  As described above, the initial operation process generates determination data based on operation data after a predetermined time has elapsed from the trigger detection time point. Then, a temporary threshold for useless operation determination is set based on the data for determination. Hereinafter, based on this threshold value, it is determined whether or not there is a waste operation.

(Normal operation processing)
Next, the normal operation process performed after the completion of the above-described initial operation process will be described with reference to the flowchart of FIG.

  In response to the completion of the initial operation process, the trigger detection unit 102 monitors the operation data stored in the operation data storage unit 108 and determines whether or not a trigger for starting the determination of useless operation has been detected ( Step S201).

  When the trigger is detected (step S201; Yes), the determination data generation unit 103 waits from the time when the trigger is detected until the operation data used for the determination is accumulated (stored) in the operation data storage unit 108. (Step S202). In this embodiment, it waits until each operation data after 5 minutes, 10 minutes, and 15 minutes are memorize | stored.

  When the operation data used for determination is stored, the determination data generation unit 103 generates data for useless operation determination from the content of the operation data (step S203). Specifically, as in the above-described initial operation process, the determination data generation unit 103 uses the temperature change rate after 5 minutes, 10 minutes, and 15 minutes from the trigger detection time as waste operation determination data. Is calculated.

  Subsequently, the waste operation determination unit 104 compares the waste operation determination data (temperature change rate) generated in step S203 with the threshold data stored in the threshold storage unit 109, thereby generating waste operation. It is determined whether or not (step S204).

  For example, when the detected trigger is a “cooling operation start” trigger, the waste operation determination unit 104 acquires threshold data corresponding to the trigger from the threshold storage unit 109. The waste operation determination unit 104 determines that the absolute value of the temperature change rate after 5 minutes from the trigger detection time is less than the temperature change rate after 5 minutes (that is, the threshold value after 5 minutes) indicated by the acquired threshold result data. It is determined whether or not there is. If it is less than the threshold value after 5 minutes, the waste operation determination unit 104 immediately determines that “there is a waste operation”. On the other hand, if the absolute value of the temperature change rate 5 minutes after the trigger detection is not less than the threshold value 5 minutes later, the waste operation determination unit 104 further 10 minutes and 15 minutes after the trigger detection time. The absolute value of the temperature change rate is compared with the threshold value corresponding to each elapsed time. As a result of the comparison, if the absolute value of the temperature change rate after 10 minutes and 15 minutes after the trigger detection is less than the corresponding threshold value, the waste operation determination unit 104 determines that there is a waste operation. Is determined. On the other hand, if not, the waste driving determination unit 104 determines “no waste driving”.

  When the detected trigger is a “cooling steady” trigger, the waste operation determination unit 104 acquires threshold data corresponding to the trigger from the threshold storage unit 109. The waste operation determination unit 104 then determines that the absolute value of the temperature change rate after 5 minutes from the trigger detection is greater than the temperature change rate after 5 minutes (that is, the threshold value after 5 minutes) indicated by the acquired threshold result data. It is determined whether or not. If it is larger than the threshold value, the waste operation determination unit 104 immediately determines that “there is a waste operation”. On the other hand, if the absolute value of the temperature change rate 5 minutes after the trigger detection is equal to or less than the threshold value 5 minutes later, the waste operation determination unit 104 further 10 minutes and 15 minutes after the trigger detection time. The absolute value of the temperature change rate is compared with the threshold value corresponding to each elapsed time. As a result of the comparison, if the absolute value of the temperature change rate after 10 minutes and 15 minutes after the trigger detection is greater than the corresponding threshold value, the waste operation determination unit 104 determines that there is a waste operation. judge. On the other hand, if not, the waste driving determination unit 104 determines “no waste driving”.

  Subsequently, the waste operation determination unit 104 includes information indicating the trigger detected in step S201 and data for waste operation determination generated in step S203 (temperature change after the lapse of 5 minutes, 10 minutes, and 15 minutes from the trigger detection time point). Rate) and the determination result data in which the information indicating the presence or absence of the wasteful driving determined in step S204 is associated with each other are stored in the determination result storage unit 110 (step S205).

  When it is determined in step S204 that there is no useless operation (step S206; No), it is not necessary to perform notification of useless operation, and the process returns to step S201.

  If it is determined in step S204 that there is a useless operation (step S206; Yes), the useless operation notifying unit 105 notifies the user of the occurrence of the useless operation by turning on an LED lamp (step S207).

  When the user is notified of the waste driving, the user evaluates whether or not the waste driving is actually performed, and inputs the evaluation result via the evaluation input unit 106. For example, when the user is performing the cooling operation of the air conditioner 2 with the doors and windows of the room being open, the cold air escapes from the air conditioner 2, and therefore, the user may evaluate (determine) that the operation is wasteful. If the door or window is closed, the user may determine that the air-conditioning management device 1 has made an erroneous determination and evaluate that there is no wasteful operation.

  When the evaluation input unit 106 receives an evaluation result from the user (step S208), the threshold adjustment unit 107 reflects the evaluation result on the determination result data (step S209). Specifically, when the evaluation result from the user indicates that there is no waste driving, the threshold adjustment unit 107 updates the determination result data recorded as having waste driving in step S205 to data indicating that there is no waste driving.

  Subsequently, the threshold adjustment unit 107 adjusts each threshold value of the threshold data from the contents of each determination result data stored in the determination result storage unit 110 (step S210).

  For example, if the threshold value data is used in the determination of the wasteful operation when the “cooling steady” trigger is detected, the threshold adjustment unit 107 acquires the determination result data corresponding to the detection of the “cooling steady” trigger from the determination result storage unit 110. To do. Then, the threshold adjustment unit 107 determines the maximum value at which the absolute value is determined to be no useless operation in the temperature change rate for each elapsed time (5 minutes, 10 minutes, 15 minutes) from the obtained determination result data. One and the smallest one determined to be useless are extracted, and an intermediate value between them is obtained. Then, the threshold adjustment unit 107 sets the obtained intermediate value for each threshold (temperature change rate) after each elapsed time of the threshold data corresponding to the “cooling steady” trigger.

  Further, if the threshold data is used in the determination of the wasteful operation when the “cooling operation start” trigger is detected, the threshold adjustment unit 107 determines from the determination result storage unit 110 the determination result data corresponding to the detection of the “cooling operation start” trigger. To get. Then, the threshold adjustment unit 107, based on the acquired determination result data, in the temperature change rate for each elapsed time, the absolute value is determined to be no useless operation and the maximum is determined to be useless operation, respectively. And the intermediate value between the two is obtained. Then, the threshold adjustment unit 107 sets the obtained intermediate value for each threshold after the passage of each time of the threshold data corresponding to the “cooling operation start” trigger.

  Here, the process of adjusting the threshold will be described with reference to FIG. FIG. 9 is a plot of the temperature change rate “after 5 minutes” of each determination result data determined when the “cooling steady” trigger is detected. The determination result data A to C indicated by “◯” determined as no useless operation and the determination result data D to F indicated by “●” determined as “useless operation” are obtained by the normal operation processing up to the previous determination result storage unit 110. It is assumed that it is stored in Further, the determination result data G indicated by ◎ is data that is newly stored and evaluated by the user by the normal operation process this time.

Here, consider a case where the data G is determined (evaluated) by the user as having a wasteful operation. In this case, the data with the smallest rate of temperature change among the determination result data determined to be useless operation is data G. Data C having the highest temperature change rate among the determination result data determined as having no wasteful operation is data C. Therefore, the threshold adjustment unit 107 sets an intermediate value between the temperature change rate of the data C and the temperature change rate of the data G to the threshold value “after 5 minutes”. The threshold adjustment unit 107 calculates the average value of the temperature change rates of the data A, B, and C determined as having no waste operation and the temperature change rates of the data G, D, E, and F having been determined as having a waste operation. An intermediate value between the average value and the threshold value “after 5 minutes” may be set.
Further, consider a case where the data G is determined (evaluated) by the user as having no unnecessary driving. In this case, the data with the highest temperature change rate among the determination result data determined as having no waste operation is data G. Further, the data D having the smallest temperature change rate among the determination result data determined to be useless operation is data D. Therefore, the threshold adjustment unit 107 sets an intermediate value between the temperature change rate of the data G and the temperature change rate of the data D to the threshold value “after 5 minutes”. The threshold adjustment unit 107 calculates the average value of the temperature change rates of the data A, B, C, and G determined as having no waste operation and the temperature change rates of the data D, E, and F having been determined as having a waste operation. An intermediate value between the average value and the threshold value “after 5 minutes” may be set.
Thus, the threshold value is adjusted to a different value according to the user's evaluation result (whether or not wasteful driving has actually been performed).

  Returning to FIG. 8, when the adjustment of the threshold value is completed, the process returns to step S201. Hereinafter, when a trigger is detected, it is determined whether or not there is a useless operation, and if there is a useless operation, this is notified, and a series of processes for adjusting the threshold according to the evaluation from the user is repeated.

  As described above, in the air conditioning management device 1 according to the first embodiment, when it is determined that there is a wasteful operation, the user is notified of the fact and an evaluation for the determination is received from the user. Then, the threshold for useless operation determination is adjusted in consideration of the evaluation. Therefore, it is possible to determine the waste operation with high accuracy.

<< Second Embodiment >>
In the first embodiment, the threshold for useless operation determination is adjusted based on the evaluation result for the useless operation determination input by the user. The second embodiment of the present invention is characterized in that the threshold for useless driving determination can be adjusted in consideration of the user's evaluation result without the input of the direct evaluation result from the user.

  As shown in FIG. 10, the air conditioning management device 10 according to the second embodiment of the present invention is different from the first embodiment in that the evaluation input unit 106 is not provided and an improvement act determination unit 111 is newly provided.

  The improvement act determination unit 111 determines whether or not an improvement action for preventing the occurrence of useless driving by the user has been performed from the content of the operation data stored in the operation data storage unit 108, and the result is a threshold adjustment unit It outputs to 107.

  Then, the process implemented with the air-conditioning management apparatus 10 is demonstrated. The initial operation process performed by the air conditioning management device 10 is substantially the same as the initial operation process performed by the air conditioning management device 1 according to the first embodiment.

  The normal operation process performed by the air conditioning management device 10 will be described with reference to the flowchart of FIG. In addition, about the same step as the normal driving | operation process of 1st Embodiment, description is simplified suitably.

  When normal operation is started and the trigger detection unit 102 detects a trigger (step S301; Yes), the determination data generation unit 103 waits until operation data used for determination is accumulated (stored) (step S302). Then, data for useless operation determination is generated from the contents of the operation data after a predetermined time has elapsed (step S303). Subsequently, the waste operation determination unit 104 determines whether or not there is a waste operation by comparing the data for waste operation determination and the threshold data stored in the threshold storage unit 109 (step S304), and the result is generated. The determination result data is stored in the determination result storage unit 110 (step S305). Subsequently, when it is determined in step S304 that there is a useless operation (step S306; Yes), the useless operation notification 105 notifies the user of the occurrence of the useless operation (step S307). The series of processing steps from step S301 to step S307 described above are substantially the same as the processing steps of the normal operation processing (step S201 to step S207 in FIG. 8) in the first embodiment.

  After notifying the wasteful operation in step S307, the improvement act determination unit 111 waits until the operation data after a predetermined time has elapsed from the notification of the wasteful operation is stored in the operation data storage unit 108 (step S308). Here, it is assumed that each operation data after the elapse of 5 minutes, 10 minutes, and 15 minutes from the notification of the waste operation is on standby until it is stored in the operation data storage unit 108.

  Subsequently, when the operation data after the elapse of a predetermined time from the notification of the wasteful operation is stored, the improvement act determination unit 111 determines whether or not the user has made an act of improvement for preventing the occurrence of the wasteful operation from the content of the operation data. It is determined whether or not (step S309). For example, the improvement action for preventing the occurrence of useless driving by the user corresponds to, for example, an action such as closing a window or a door that has been opened so that cold air does not escape.

If the trigger detected in step S301 is a “cooling operation start” trigger, it may be determined whether or not an improvement act has been performed as follows. First, the improvement act determination unit 111 acquires each operation data after 5 minutes, 10 minutes, and 15 minutes from the notification of the wasteful operation. Subsequently, the improvement act determination unit 111 calculates the temperature change rate after 5 minutes, 10 minutes, and 15 minutes from the waste operation notification from each acquired operation data. Subsequently, the remedial action determination unit 111 calculates the threshold value (temperature) for each elapsed time of the calculated absolute value of each temperature change rate and the threshold data corresponding to the “cooling operation start” trigger stored in the threshold storage unit 109. Change rate). Then, as a result of the comparison, if the temperature change rates after 5 minutes, 10 minutes, and 15 minutes have elapsed from the waste driving notification are all equal to or higher than the corresponding threshold values, an improvement act has been made. What is necessary is just to discriminate | determine that it is what has not been made in other cases.
Alternatively, the improvement act determination unit 111 acquires a plurality of driving data around a predetermined time from the waste driving notification. Then, the improvement act determination unit 111 determines whether or not the ratio of the room temperature decrease with respect to the time after the waste driving notification is larger than the ratio of the room temperature decrease with respect to the time before the waste driving notification by a predetermined value or more from the acquired plurality of operation data. If it is large, it may be determined that there has been an improvement act.

If the trigger detected in step S301 is a “cooling steady” trigger, it may be determined whether or not an improvement act has been performed as follows. First, the improvement act determination unit 111 acquires each operation data after 5 minutes, 10 minutes, and 15 minutes from the notification of the wasteful operation. Subsequently, the improvement act determination unit 111 calculates the temperature change rate after 5 minutes, 10 minutes, and 15 minutes from the waste operation notification from each acquired operation data. Subsequently, the improvement act determination unit 111 compares the calculated absolute value of each temperature change rate with the threshold value for each elapsed time of the threshold data corresponding to the “cooling steady” trigger stored in the threshold value storage unit 109. To do. Then, as a result of the comparison, if the temperature change rates after 5 minutes, 10 minutes, and 15 minutes from the wasteful operation notification are all equal to or less than the corresponding threshold values, the improvement action determination unit 111 performs the improvement action. In other cases, it may be determined that no improvement has been made.
Alternatively, the improvement act determination unit 111 acquires a plurality of driving data around a predetermined time from the waste driving notification. And the improvement act determination unit 111 determines whether or not the difference between the set temperature after the waste operation notification and the room temperature is smaller than that before the waste operation notification from the plurality of acquired operation data. It may be determined that there has been an improvement act.

  When it is determined that the improvement act has been performed (step S309; Yes), it is estimated that the user evaluated the notification of the wasteful driving as correct and then performed the improvement action. Therefore, the result of determining that there is a wasteful operation in step S304 is correct, and the process moves to step S311.

  If it is determined that no improvement action has been taken (step S309; No), it is estimated that the user has evaluated that the notification of wasteful driving is incorrect, and then no improvement action has been performed. Therefore, the threshold adjustment unit 107 updates the determination result data stored as having a waste operation in step S305 to data indicating that there is no waste operation (step S310), and moves the process to step S311.

  In step S <b> 311, the threshold adjustment unit 107 adjusts each threshold value of the threshold data based on the content of each determination result data stored in the determination result storage unit 110. This process is substantially the same as the process during normal operation (step S210 in FIG. 8). When the adjustment of the threshold is completed, the process returns to step S301. As described above, when a trigger is detected, a wasteful operation is determined and notified, and a series of processes for adjusting the threshold according to the presence or absence of an improvement action by the user is repeated.

  As described above, the air conditioning management device 10 determines whether or not an improvement action for preventing the unnecessary operation has been performed after the notification of the unnecessary operation. If the improvement action is performed, there is a wasteful driving, and if the improvement action is not performed, it is determined that the user has evaluated that there is no wasteful driving. Adjust the threshold. Therefore, the air-conditioning management apparatus 10 can determine the waste operation with high accuracy as in the air-conditioning management apparatus 1 of the first embodiment. Moreover, since the user does not need to directly input the evaluation result for the determination of the wasteful driving, the convenience can be further improved. In addition, since the air conditioning management device 10 does not need to include a button or the like for receiving an evaluation input from the user, the number of mounted components can be reduced, and downsizing and cost reduction can be expected.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  For example, in each of the above-described embodiments, the three temperature change rates after 5 minutes, 10 minutes, and 15 minutes after the trigger detection are used as the data for determining the wasteful operation. However, the present invention is not limited to this. It is not necessary, and wasteful operation may be determined using a higher number of temperature change rates or a temperature change rate after another time. Alternatively, the waste operation may be determined using only the temperature change rate after 5 minutes from the trigger detection time.

  Further, in each of the above embodiments, the wasteful operation is determined when the “cooling operation start” trigger and the “cooling steady state” trigger are detected. However, the trigger for starting the determination of useless driving is not limited to these. For example, the determination of useless operation may be started when a fixed time of the day comes or when the heating operation is started. In this case, threshold data corresponding to these triggers needs to be stored in the threshold storage unit 109.

  Further, in each of the above embodiments, the temperature change rate is used as data for useless operation determination. However, the presence / absence of the useless operation may be determined using other data such as a difference between the room temperature and the set temperature, a slope with respect to the room temperature time (time change rate of the room temperature), and the like.

  In addition, for example, by applying an operation program that defines the operation of the air conditioning management device according to the present invention to an existing personal computer, information terminal device, or the like, the personal computer or the like can function as the air conditioning management device according to the present invention. Is also possible.

  Such a program distribution method is arbitrary, for example, a computer-readable recording medium such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card. It may be stored and distributed in a network, or distributed via a communication network such as the Internet.

  The present invention can be suitably employed in an air conditioning system installed in a building or the like.
