In addition, in order to prevent unexpected power consumption when going out, a technology has been proposed to detect the presence or absence of abnormal use of power by comparing the reference power value registered with the user with the used power value ( For example, see Japanese Patent Application Publication No. 2007-132804 (hereinafter referred to as Document 2)).

Since the technology described in the above-mentioned document 1 determines that the power supply is detected when the power supply is detected in the outing mode, it is actually determined that the user has forgotten to delete even when the user is not out there is a possibility.

On the other hand, the technique described in the above-mentioned document 2 compares the reference power value and the power usage value when the check button is pressed. That is, when the power consumption value is expected to be less than or equal to the reference power value, the technique described in the above-mentioned document 2 presses the check button, and at this time, the power usage value exceeds the reference power value. It is determined that abnormal use (that is, unexpected power consumption occurs).

After all, in the techniques described in the above-mentioned documents 1 and 2, it is necessary for the user to indicate the timing of the judgment of forgetting to erase.

An object of the present invention is to provide a monitoring device that does not require the user to indicate the timing at which it is determined that the electric device has forgotten to be erased.

It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment. It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment. It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment.

The monitoring device 10 described below has the configuration shown in FIG. The monitoring device 10 can be implemented in various devices. In the embodiment described below, as shown in FIG. 2, a plurality of devices 20 (only one is shown in FIG. 2) used in the house 30 is targeted for monitoring, and the monitoring device 10 is installed in the house 30. A configuration example for communicating with a HEMS controller (HEMS: Home Energy Management System) 21 is assumed. That is, in the configuration example illustrated, the monitoring device 10 is realized by the computer server 101 communicating with the HEMS controller 21 and the computer server 102 communicating with the terminal device 22.

The house 30 is not limited to a single-family house, but may be a collective house. The device 20 is not limited to use in the house 30, and the technology of the present embodiment can be adopted when used in an office building, a store building, or the like.

The monitoring device 10 is configured with a computer as a main hardware element, and is configured by executing a program that causes the computer to function as the monitoring device 10 described below. The program is preferably provided using a computer readable recording medium. The HEMS controller 21 also includes a processor that operates by executing a program.

Hereinafter, the HEMS controller 21 is simply referred to as a controller, and the

computer servers

101 and 102 are referred to as servers. The terminal device 22 may be a communicable device such as a smartphone, a tablet terminal, or a personal computer, and may have a function of presenting information and a function of instructing the

servers

101 and 102.

The controller 21 has a function of acquiring the power consumption value measured by the measuring device 31 and transmitting the acquired power consumption value to the server 101. The measuring device 31 measures the power passing through each branch circuit branched by the distribution board 32 installed in the house 30. The equipment 20 used in the house 30 is supplied with power from a branch circuit branched by the distribution board 32.

The measuring device 31 includes a current sensor selected from a clamp type current transformer, a Rogowski coil, etc., and uses the current value detected by the current sensor and the voltage value between the lines in the branch circuit to determine the power value for each branch circuit. Calculate The average value of the amount of power per unit time is actually used as the calculated power value. The unit time is selected in the range of 1 second to 10 minutes, preferably 30 seconds or 1 minute.

In the illustrated example, the controller 21 and the server 101 communicate via a telecommunication line NT1 such as the Internet. When the telecommunications line NT1 is the Internet, a technology such as VPN (Virtual Private Network) is used to protect the communication contents, and the controller 21 connects to the telecommunications line NT1 through the router 23 equipped with a firewall. There is a need. On the other hand, the terminal device 22 communicates with the server 102 through a telecommunication line NT2 such as a mobile communication network or the Internet. The telecommunication line NT2 may be shared with the telecommunication line NT1.

It is desirable that the server 101 and the server 102 communicate via a communication path separate from the telecommunication lines NT1 and NT2. The server 101 and the server 102 may be configured to share the same hardware. The server 102 mainly has a function of generating output information of the monitoring device 10 and presenting the output information to the terminal device 22. On the other hand, the server 101 has a function of detecting forgetting to erase by using information acquired mainly from the controller 21.

Here, since the server 101 analyzes the time change of the information acquired from the controller 21, the server 103 for temporarily storing the information transmitted from the controller 21 is provided between the controller 21 and the server 101. May be Moreover, the controller 21 of this embodiment acquires information from the human sensor 24 which monitors the presence or absence of a person for each room in the house 30.

The human sensor 24 employs a pyroelectric infrared sensor to detect infrared rays emitted from the human body. However, if it is necessary to detect the presence or absence of a person more accurately than the pyroelectric infrared sensor, even if a configuration for detecting the presence or absence of a person by computer image processing of an image taken by a television camera as the person detection sensor 24 is adopted. Good.

As shown in FIG. 1, the monitoring device 10 configured by the

servers

101 and 102 relates to the first acquisition unit 11 that acquires information on the power consumption value from the controller 21 and the presence or absence of a person detected by the human sensor 24. And a second acquisition unit 12 for acquiring information. The first acquisition unit 11 does not cover all the devices 20 managed by the controller 21 but acquires information on power consumption values for the devices 20 selected as the monitoring targets.

The device 20 to be selected as the monitoring target may normally be the device 20 operated by a person. For example, equipment 20 such as an air conditioner, IH cooking heater, lighting fixture, heating equipment (electric floor heater, electric stove, electric cooker, electric kotatsu, electric blanket, etc.) can be selected as a monitoring target. On the other hand, it is desirable that equipment 20 which is not normally operated by a person, such as a refrigerator or a hot water storage type water heater, be excluded from monitoring targets.

As described above, since the power consumption value of the device 20 is obtained for each unit time, the first acquisition unit 11 uses the controller 21 as the power information in which the power consumption value corresponds to the date and time when the power consumption value was measured. Get from That is, the first acquisition unit 11 acquires information on time change related to the power consumption value of the device 20 to be monitored. In addition, the second acquisition unit 12 may use information regarding the presence or absence of a person in a space where the device 20 selected as a monitoring target is used (that is, a space where the device 20 is disposed when consuming power). Acquired from the controller 21.

The monitoring apparatus 10 outputs the determination result on forgetting erasure using the information on the change in time related to the power consumption value acquired by the first acquisition unit 11 and the information on the presence or absence of the person acquired by the second acquisition unit 12 The determination unit 13 is provided. The determination unit 13 determines whether the device 20 is in the candidate state for forgetting to erase based on the use state of the device 20 and the use time of the device 20. Further, the determination unit 13 outputs a determination result when the information acquired by the second acquisition unit 12 indicates the absence of a person during a period in which the device 20 is determined to be in the candidate state.

The use state of the device 20 and the use time of the device 20 are extracted from the information of the time change regarding the power consumption value of the device 20. The power consumption value increases during a period in which the device 20 is operating as compared to a period in which the device 20 is not operating. Using this, the determination unit 13 sets an appropriate threshold value for the power consumption value, regards the state where the power consumption value exceeds the threshold as the state where the device 20 is operating, and the device 20 is operating. The time during which the state continues is regarded as the use time of the device 20. Hereinafter, the threshold set for the power consumption value is referred to as a power determination value.

The power determination value as a threshold for the power consumption value is a value smaller than the minimum value of the power consumption value during the period in which the device 20 is operating and greater than 0 for the device 20 that does not consume power during the inactive period It is determined in In addition, for the device 20 that consumes power as standby power even in a non-operation period, the value is smaller than the minimum value of the power consumption value of the period in which the device 20 is operating and larger than the value of the standby power The power judgment value is determined in

If the power determination value is appropriately set, the determination unit 13 can determine whether the device 20 is operating or not operating based on the time change of the power consumption value. . In addition, the determination unit 13 can extract the date and time when the operation of the device 20 starts and the use time until the operation of the device 20 stops based on the time change of the power consumption value. As described above, the measured power consumption value corresponds to the measured date and time.

Therefore, the determination unit 13 obtains the date when the power consumption value exceeds the power determination value as the date when the device 20 starts the operation, and thereafter, the device 20 operates the date when the power consumption value becomes less than the power determination value. Calculated as the date and time when it stopped. The determination unit 13 obtains, as the use time of the device 20, the time from the date when the device 20 starts operation to the date when the device 20 stops operation.

By the way, in the state of forgetting to erase the device 20, the user is not aware that the device 20 is operating and is operating. On the other hand, if the user knows that the device 20 is operating, even if the device 20 is being used continuously for a long time, it can not necessarily be said that the device 20 has been erased. When a person is absent in the space in which the device 20 is used, the determination unit 13 of the present embodiment determines that the device 20 has been continuously erased and has forgotten to be erased, on the condition that the device 20 is continuously operating.

Therefore, the determination unit 13 determines whether the device 20 is in the candidate state for forgetting to erase, using the use state and the use time of the device 20 extracted from the information of the time change of the power consumption value. The candidate state is a state in which the device 20 is a candidate for forgetting to erase, and normally, if the period in which the device 20 is determined to be operating is long, the state in which the device 20 is operating is long. Become. Here, the determination unit 13 not only determines that the device 20 is in the operating state when the power consumption value exceeds the power determination value, but the power consumption value exceeds the power determination value. It is determined that the device 20 is in the candidate state when the duration of the presence state exceeds the predetermined period determination value. The power determination value and the period determination value used to determine the candidate state are set according to the device 20.

As described above, the determination unit 13 determines that the device 20 is in the candidate state when the duration of the state where the power consumption value exceeds the power determination value exceeds the predetermined period determination value. It is desirable to be configured to According to this configuration, if the power determination value and the period determination value are appropriately set with respect to the information on the time change of the power consumption value, the determination unit 13 can easily determine the candidate state. .

Note that, depending on the type of the device 20, the power consumption value may greatly fluctuate in the state of being continuously used. For example, in an apparatus 20 such as an iron or oven toaster, the power consumption value may increase rapidly until the predetermined temperature is reached, and thereafter, the power consumption value may repeatedly increase and decrease. In such an apparatus 20, the state where the power consumption value exceeds the power determination value and the state where the power consumption value becomes equal to or less than the power determination value may be repeated while the device 20 is operating. Therefore, for this type of device 20, the determination unit 13 must determine that the period in which the power consumption value repeatedly increases and decreases is continuously being used. For example, when the power consumption value falls below the power judgment value from the state where the power consumption value exceeds the power judgment value, the judgment unit 13 suspends the judgment, and after the predetermined judgment time has elapsed, the power consumption is judged as the power If it does not exceed the value, it may be determined that the operation of the device 20 has stopped.

The power determination value and the period determination value are set for each device 20 and stored in the storage unit 131 provided in the determination unit 13. The power determination value and the period determination value may be generally set in advance for each type of the device 20 at the stage of manufacturing the monitoring device 10. However, in order to set the power determination value and the period determination value more appropriately, it is preferable that the administrator of the monitoring apparatus 10 set the details after analyzing the history of the past power consumption value for the corresponding device 20 . The power determination value and the period determination value are determined according to each device 20. Further, depending on the device 20, the power determination value and the period determination value may change depending on the season, and may change depending on whether it is a weekday or a holiday.

The determination unit 13 performs a process of extracting the device 20 in the candidate state based on the information of the time change of the power consumption value, and the information on the presence or absence of the person acquired by the second acquisition unit 12. And a person determination unit 133 for dividing the period into a period in which a person is present and a period in which a person is absent. The storage unit 131, the device determination unit 132, and the person determination unit 133 are configured by dividing the determination unit 13 into functional modules, and these modules need to correspond one-to-one with hardware elements. Absent.

The first acquisition unit 11, the second acquisition unit 12, and the determination unit 13 are configured by the server 101, and the determination result output by the determination unit 13 is handed over to the server 102. The server 102 generates output information using the determination result of the determination unit 13 and configures a presentation control unit 14 that causes the terminal device 22 as a presentation device to present the output information. The output information generated by the presentation control unit 14 is notified to the terminal device 22 registered in advance as a notification destination by a push method.

The output information generated by the presentation control unit 14 upon receiving the determination result of the determination unit 13 constitutes, for example, the screens illustrated in FIGS. 3 to 5. The illustrated example assumes a configuration in which the terminal device 22 is a smartphone or a tablet terminal, and includes an operation display device in which a transparent touch panel is superimposed on the screen of the display.

The output information on the screen shown in FIG. 3 includes information specifying the corresponding device 20 and information specifying the space in which the corresponding device 20 is used. Further, the output information on the screen shown in FIG. 4 includes information specifying the corresponding device 20, information specifying the space in which the corresponding device 20 is used, and the time when use of the corresponding device 20 was started. , And the time during which use of the corresponding device 20 is continued. Furthermore, the output information on the screen shown in FIG. 4 includes information on the contact and information on the contact method.

The fields displayed on the screen shown in FIG. 3 are a content field F11 for displaying the notification content, a button field B11 for returning the confirmation of the notification content to the server 102, and the notification content in more detail. And a button field B12 operated to confirm. The screen shown in FIG. 4 is an example of a screen displayed after the button field B12 of FIG. 3 is touch-operated, and information on time is added as notification content. The fields displayed on the screen include a content field F21 for displaying the notification content, and button fields B21 and B22 in which the contact address and the contact method in the case of contacting in response to the notification content are associated.

In this screen, a button field B23 for presenting a graph of the usage amount is also added. When the button field B23 is touch-operated, as shown in FIG. 5, a field F31 indicating the amount of power consumed by the corresponding device 20 for every predetermined time (for example, one hour) in a predetermined period of about one day is a bar graph. It is displayed on the screen. Since a time change after the power consumption value of the device 20 rises is shown on the screen shown in FIG. 5, the user can use the indication as a criterion to determine whether the device 20 has forgotten to be erased.

As described above, the monitoring device 10 according to the present embodiment includes the first acquisition unit 11, the second acquisition unit 12, the determination unit 13, and the presentation control unit 14. The first acquisition unit 11 is configured to acquire time change information related to the power consumption value of the device 20 to be monitored. In addition, the second acquisition unit 12 is configured to acquire information regarding the presence or absence of a person in the space where the device 20 is used. The determination unit 13 extracts the usage state of the device 20 and the usage time of the device 20 from the information of the time change regarding the power consumption value, and uses the usage state of the device 20 and the usage time of the device 20 It is configured to determine whether or not it is in the state. In addition, the determination unit 13 is configured to output the determination result when it is determined that the device 20 is in the candidate state and the second acquisition unit 12 acquires information indicating absence of a person. Be done. The presentation control unit 14 is configured to cause the predetermined presentation device (terminal device 22) to present output information based on the determination result of the determination unit 13.

According to this configuration, the determination unit 13 extracts the use state and the use time of the device 20 from the information of the time change regarding the power consumption value of the device 20, and uses the use state and the use time of the device 20 to erase the device 20. It is determined whether or not it is in the candidate state for forgetting. Furthermore, the determination unit 13 outputs the determination result when it is determined that the device 20 is in the candidate state and information indicating the absence of a person is obtained. Therefore, when there is a possibility that the user is absent in the space in which the device 20 is used and the user is not aware that the device 20 is in the operating candidate state, the output information is presented and used. It is possible to make people aware.

In the monitoring device 10, the determination unit 13 determines that the device 20 is in the candidate state when the duration of the state where the power consumption value exceeds the power determination value exceeds the predetermined period determination value. Preferably, it is configured to

In addition, when a schedule is set for the operation of the device 20, the determination unit 13 is configured to determine whether the device 20 is in the candidate state during the period in which the device 20 stops operation in the schedule. May be

In the configuration example described above, the measuring device 31 measures the power consumption value for each branch circuit branched by the distribution board 32. Therefore, if the devices 20 are not connected one-to-one to the branch circuit, the power consumption value acquired by the first acquisition unit 11 may be a combination of the power consumption values of the plurality of devices 20. In other words, there are cases where the power consumption value related to the device 20 to be monitored can not be separated from the power consumption value acquired by the first acquisition unit 11.

Therefore, the monitoring apparatus 10 may have a configuration for extracting the power consumption value of each device 20 from the power consumption value of the branch circuit by extracting the feature amount of the device 20 from the time change of the power consumption value. Further, since the controller 21 can communicate with the device 20, it is possible to extract the power consumption value of each device 20 by combining the identification information of the device 20 which the controller 21 grasps with the power consumption value. .

If the receptacle to which the device 20 is connected is provided with a configuration for measuring the power consumption value, the controller 21 may acquire the power consumption value from the receptacle. In addition, if the device 20 has a function of measuring the power consumption of the device 20, the controller 21 may acquire the power consumption value from the device 20.

The embodiment described above is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and even if it is a range other than this embodiment, various modifications may be made according to design etc. as long as the technical idea of the present invention is not deviated. Of course it is possible to change.

For example, in the configuration example described above, the output information is displayed on the terminal device 22 as the presentation device. However, if a configuration in which the output information is presented by voice to the terminal device 22 is adopted, the user is deaf. Will also be available. Further, in the configuration example described above, the monitoring device 10 is realized in the

servers

101 and 102, but the monitoring device 10 can also be realized in the controller 21 if the processing capability of the processor configuring the controller 21 is high.
