Description

  The present invention relates to a device control apparatus and a device control method, and relates to a technique for controlling a device with reference to a preset action pattern.

Technology that stores the operating status of equipment installed in a building in advance as normal-time behavior data, and compares it with normal-time behavior data to determine the current status and predict future behavior, and perform control Is already known.
As such a technique, for example, the normal behavior of a single person is stored as a time-series pattern of power consumption, and the stored pattern is compared with the acquired pattern to determine whether an abnormality has occurred. There is a known technique for determining. For example, in this technique, a threshold value is set for each item, an item exceeding the threshold value is determined to be abnormal, and notification or the like can be performed (see, for example, Patent Document 1). .

Also, a system for predicting the behavior of a resident is known.
In this system, the action schedule information input from the scheduler is acquired, the action of the user is predicted from this action schedule information, and the devices used and not used by the user are predicted. The device predicted to be used can be operated according to the scheduled time at the place associated with the user's action (see, for example, Patent Document 2).

  As described above, the behavior pattern of the user (resident) is acquired as data by some method, and by using the behavior pattern, the current user (resident) or the state of the residence is estimated, or the behavior Various techniques for controlling devices by using patterns have been proposed.

JP, 2005-216113, A JP-A-2015-125555

By the way, if the control associated with the behavior pattern is invariable once determined, it may not match the behavior pattern of the inhabitants due to factors such as fluctuation of the behavior pattern of the resident and seasonal fluctuation.
For this reason, it is necessary to update (including correction) the control by updating the data regarding the action pattern, and this update (including correction) may be performed by more reflecting the daily actions of the user. Desirably, it is necessary to perform control in accordance with an action pattern updated in association with daily life.
Then, when performing control associated with an action pattern, a trigger for starting the control is determined, but it is necessary to precisely determine the balance between the trigger and the update (including correction) of data regarding the action pattern. . That is, it is necessary to set an appropriate trigger according to the user's action pattern, and it is necessary to determine the necessity of trigger change and the like in response to the update (correction).

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to control a target device (for example, to monitor in a configuration capable of executing control according to a user's action). An object of the present invention is to provide a device control device and a device control method capable of performing simple and reliable control.

According to the device control device of the present invention, the problem is that a storage unit that stores the state of the control target device to be controlled at a predetermined interval, and the state of the control target device at a predetermined time stored in the storage unit. Then, by comparing with the current state of the controlled device, it is determined whether the current is a controlled period or a non-controlled period, and it is determined that the current is the controlled period. In the case where the control target device is present, a process execution unit that performs a predetermined determination on the control target device, and a device state list for a predetermined period that collects the states of the control target device at the predetermined time point from the control target device at the predetermined time point Is provided with an update unit that creates behavior pattern data that is statistically estimated. The storage unit stores the behavior pattern data, and the process execution unit reads the behavior pattern data from the storage unit. The storage of the state of the control target device at the predetermined time point in the action pattern data, and the state of the control target device at the current time are compared, and when the match is a predetermined ratio or more, the present is the control target period. It is solved by determining that

According to the present invention, the state of the control target device at a predetermined time point (time when the predetermined determination is almost surely made: core time) is stored, and the stored state and the current control target device are stored. It is possible to recognize whether the present is a controlled object period or a non-controlled object period by comparing the states of. Then, when it is determined that the current period is the control target period, a predetermined determination (for example, device monitoring) is executed.
As described above, according to the present invention, it is possible to easily and surely perform control according to the user's action.

Hereinafter, a specific description will be given with reference to FIG.
The device monitoring control system S according to the present embodiment includes the device 1, a hub 2, an adapter 3, and a control target device 4.
The device 1 includes a home server (an example of a computer) installed in a house, and is connected to each control target device 4 via a hub 2.
Specifically, the wired LAN branched from the hub 2 is connected to each control target device 4 via each adapter 3, whereby the device 1 controls each control target device 4. In addition to being possible, the operating state of each controlled device 4 is transmitted to the device 1.
It should be noted that these may be configured as a wired IP network using an Ethernet (registered trademark) cable or a wireless IP network using IEEE802.1x or Bluetooth (registered trademark), for example.
In addition, as will be described later as an example, the control target device 4 is used as a general term to refer to all devices connected to the device 1. In the present embodiment, devices to be installed in and around the house are referred to as devices to be installed. Used as a generic term. Therefore, in the present embodiment, the plurality of devices are collectively referred to as the control target device 4.

The hub 2 according to the present embodiment may use a known switching hub or the like, and connects the device 1 and each adapter 3 to each other.
As the adapter 3, a known communication adapter or control adapter is used.
As described above, in the present embodiment, the air conditioner 41, the electric shutter 42, the entrance lock 43, the lighting device 44, the window lock 45, and the ventilation fan 46 are illustrated as the control target devices 4. It should be noted that the control target device 4 is not limited to this, and all controllable devices in the house can be targeted.

The hub 2 and the air conditioner 41 are connected via the air conditioning control adapter 31, and similarly, the hub 2 and the electric shutter 42 are connected via the shutter communication adapter 32.
Similarly, the hub 2 and the entrance lock interface unit 43a constituting the entrance lock 43 are connected via a entrance lock control adapter 33 (a so-called "JEM-A control adapter" is preferably used). Further, the hub 2 and the lighting switch 44 a forming the lighting device 44 are connected via a lighting control adapter 34.
Further, the hub 2 and the window lock 45 are connected via the window lock communication adapter 35, and the hub 2 and the ventilation fan 46 are connected via the ventilation fan communication adapter 36.

Has been done.
Although the adapter 3 is used in the present embodiment, the adapter 3 is not essential. That is, the control target device 4 may be directly controlled without the intervention of the adapter 3.

Further, each of the control target devices 4 provided in the house, including the air conditioner 41 and the lighting device 44, is provided with an operated device that is operated to switch the operating state. The “operated device” is a device that is operated to individually switch the operating state of each device, and it is already installed in the house at the time of moving in, or it is introduced into the house along with the purchase and installation of the device. To do. By operating this operated device, it is possible to switch the operating state of the corresponding energy consuming device without going through the present device 1 (in other words, without performing the control process of the present device 1).
The operated device may be separated from the device whose operating state is switched by the operation, or may be integrated with the device (for example, a part of the device). Good.

An example of the operated device will be specifically described according to the present embodiment. For example, a remote controller 41a that issues a switching signal for switching the operating condition of the air conditioner 41 or an electric shutter drive device 42a that issues an elevating signal of the electric shutter 42. For example, a lighting switch 44a for switching on / off of the lighting device 44 is applicable.
In the present embodiment, the device 1 monitors the operating state of each of the control target devices 4 by communicating with the control target devices 4 through the network built in the device monitoring control system S. Further, it is also possible to remotely and automatically control the operating states of these controlled devices 4.
The “operating state” refers to the current state of items that can be controlled (adjusted) with respect to driving, such as start / stop (on / off), driving details (driving mode), and driving control values.

Then, in the present embodiment, the state of the control target device 4 in a predetermined period is detected, a "device state list" in a predetermined period is created, and "action pattern data" is created from this device state list.
Next, the "predetermined control start operation device" for recognizing that the predetermined period which is the monitoring target period has started is selected from this device state list. When it is determined that the "predetermined period" has started, the state of the control target device 4 set as the "monitoring device" is detected, and if the detection result is different from the designated result, " By driving the controlled device 4 set as the “notification device” to a predetermined state, the user is notified that the detection result is different from the designated result.
Hereinafter, as an example of the embodiment, control device monitoring at the time of sleeping will be described. Therefore, the “predetermined period” is the “sleeping period”, and the “predetermined control start operation device” is the “sleeping operation device”.

  By the way, the controlled device 4 is not limited to the exemplified one, of course, and the type and the number of the controlled device 4, the installation location, etc. can be arbitrarily determined.

<< Outline of Monitoring of Control Target Device by Device Monitoring and Control Apparatus According to this Embodiment >>
Next, an outline of a method of monitoring and controlling the controlled device 4 by the device 1 will be described.
In the present embodiment, a device to be controlled is selected from the controlled devices 4 and used according to the purpose.
In the present embodiment, as one specific example, in order to describe the configuration and control in which the purpose is “monitoring control at bedtime”, “entrance lock 43” is selected as the “monitoring device”. As the “sleeping operation device”, the “illumination device 44” is selected in the initial state. Further, the “illumination device 44” is selected as the “notification device”.

That is, in the present embodiment, in the initial state, the lighting device 44 is selected as a bedtime operation device and also as a notification device, and an abnormality (forgetting to lock) occurs in the entrance lock 43. When it is detected that the door lock 43 is changed, the light emission pattern of the illumination device 44 is changed to notify the user of the abnormality (forgetting to lock) the entrance lock 43.
It is preferable that the lighting device installed in the bedroom is “lighting device 44”. This is because it is generally estimated that the lighting device 44 is the last device to be operated at bedtime, and when an abnormality is detected in the immediate state of going to bed, This is because it is estimated that the lighting device 44 is also the device that the user is most likely to pay attention to.
Of course, different control target devices 4 may be selected as the bedtime operation device and the notification device. In addition, these devices are selected according to the shape of the house, the shape / arrangement of the room, the lifestyle of the user, and the like, and this embodiment is merely an example.

As will be described later, in the present embodiment, the bedtime operation device refers to the device state list along with the creation (update) of the action pattern data and responds to the user's life from among the control target devices 4. Appropriate equipment will be selected.
In addition, when there is a change in the layout, a change in the lighting position, or the like, the notification device can be changed. This may be configured such that the device 1 is provided with house plan information and the optimum notification device is automatically selected from the house plan information, or the user can set it. Good. With this configuration, if the housing plan information is rewritten due to a change in the floor plan, etc., it is possible to automatically select the notification device existing in the optimum position, and the notification device can be appropriately changed according to the convenience of the user. It is possible to change.
Hereinafter, a detailed description will be given with reference to FIGS.

<< Configuration of Device Monitoring and Control Device According to This Embodiment >>
Next, the configuration of the device 1 will be described. As described above, the device 1 is composed of a home server (computer), and has a CPU, memories such as ROM and RAM, a communication interface, and a hard disk drive. It should be noted that the monitor may also be properly connected.

  In addition, a computer program (hereinafter, device control program) for exhibiting the function of the home server is installed in the memory or the hard disk drive. When the device control program is read and executed by the CPU of the home server, the home server as the device 1 executes a series of data processing relating to device monitoring control of the house.

With reference to the block diagram of FIG. 2, the configuration of the present device 1 will be briefly described in terms of function.
As shown in FIG. 2, the present device 1 is configured to include a process execution unit 11, a detection unit 12, an update unit 13, and a storage unit 14. The functional units (that is, the process execution unit 11, the detection unit 12, the update unit 13, and the storage unit 14) described above are such that the hardware device of the home server forming the device 1 cooperates with the device control program as software. It is realized by. Hereinafter, each functional unit will be briefly described.

  The process executing unit 11 executes a control process for controlling the operation of the controlled device 4 according to the control flow. In particular, in the present embodiment, a predetermined control start operation device (specifically, the lighting device 44) and Upon receiving a signal from the monitoring device (specifically, the entrance lock 43), the operating state of the detection device (specifically, the lighting device 44) is controlled (specifically, the lighting device 44 is set in a predetermined pattern). The control process is executed.

The detection unit 12 detects the state of the control target device 4 (on / off state, operation execution). More specifically, the home server configuring the present device 1 includes a receiver (not shown), and a transmission signal from each adapter 3 connected (wired and wireless) to each control target device 4 Is received by the above-mentioned receiver, and the state of the controlled device 4 (on / off state or operation execution) is detected from the signal reception. Note that, for example, in the case of the lighting device 44, the switching of the on / off state is recognized, and the operation of the lighting device 44 is detected from this state change.

The update unit 13 is a device for a predetermined period, which is a history (state history) regarding a state of each control target device 4 detected by the detection unit 12 during a predetermined period (during sleep time in the present embodiment), a time when the state is changed to the state, and the like. The state list is reconstructed and the behavior pattern data is reconstructed accordingly. Then, based on this behavior pattern data, a predetermined control start time operation device (in the present embodiment, a bedtime operation device) is selected. Further, when the notification device is changed, the notification device is also changed. In this way, the update unit 13 updates (reconstructs) data necessary for device monitoring control, such as the operation device at the start of predetermined control and the notification device, by updating the action pattern data, and transmits it to the storage unit 14. To do.
Further, in the present embodiment, the time assumed to be definitely within the predetermined period is set as the “core time” and is stored in the storage unit 14, but this core time is a common sense for the purpose of control. The time that can be assumed in advance may be set in advance and may remain unchanged, and this core time is also updated based on the behavior pattern data as described above, and the updated core time is stored in the storage unit 14. May be
Further, the core time may be changeable by the user's intention by the user's input operation.

  The storage unit 14 stores a program for executing the device monitoring control flow of the house, data necessary for executing the program, and the like. That is, the device state list and the action pattern data for the latest predetermined period, information indicating the predetermined control start operation device, the notification device, and the like are stored.

3 and 4 are conceptual diagrams of the device state list and the action pattern data stored in the storage unit 14 for a predetermined period.
In the present embodiment, an example relating to the behavior pattern follow-up type supervisory control at bedtime is shown. Therefore, FIG. 3 is a conceptual diagram showing a “sleeping device state list” as the “predetermined period device state list”.
Unlike the conventional monitoring control, the "behavior pattern following type monitoring control" is control that automatically executes monitoring control by referring to the behavior pattern of the inhabitants. That is, in the conventional supervisory control, for example, the inhabitants needed to issue a control start command by operating the switch of the control and monitoring device, but in the action pattern following supervisory control, referring to the inhabitants' action patterns, It is configured to determine whether or not the supervisory control is necessary and to start the supervisory control by operating a trigger according to the behavior pattern of the inhabitants.
In the present embodiment showing the control at bedtime, the “core time” is a time at which it is estimated that the person is surely going to bed, and is therefore referred to as “sleeping core time”.

As shown in FIG. 3, in the bedtime device state list, what state each control target device 4 is in at the sleeping core time, the state before the transition to the state, and the state transition. Is a list stored according to the device ID.
That is, each controlled device 4 is managed according to a unique device ID, and each data is stored for each device ID.
Specifically, the device name (installation place), the state at the sleeping core time, the state before the transition to the sleeping core time, and the transition time are set for each device ID for all the control target devices 4 in the house. It is recorded.
The state before the transition to the state of the sleeping core time is stored in order to grasp what state change the controlled device 4 changes, and the storage of the transition time corresponds to the sleeping time. This is to distinguish between state changes at night and state changes at other times.
In FIG. 3, for example, in the case of “living room lighting”, information that “it is off at the sleeping core time and has changed from the on state that is the pre-transition state to the off state at the transition time 0” is stored. Has been done.
It should be noted that the device ID can also refer to position information, plan information, and the like.
Further, this bedtime device state list holds information on the control target device 4 operated by the user's active intention, and does not target the one by timer control or the like.
This bedtime equipment state list serves as data for selecting a bedtime operation device or the like.
Note that data collection is not covered by timer control as described above, but for example, data transmitted from a dedicated remote control operated by the user, on / off of equipment in the building, etc. are centrally managed. What is transmitted via the device that is being targeted can be targeted.

Then, the behavior pattern data shown in FIG. 4 is created by the updating unit 13 by analyzing the information of the bedtime equipment state list collected for a certain period, and is stored in the storage unit 14. This action pattern data is a list in which the times at which transitions of the control target devices 4 occur are stored according to the device ID.
That is, the average value (busiest value) of the bedtime core time states is held as the bedtime state of the action pattern data from the bedtime device state list collected for a certain period.
Then, the range of transition time is held at the transition time of the action pattern data from the bedtime device state list collected for a certain period.
In the present embodiment, in order to improve the accuracy, as the action pattern data at bedtime, the behavior pattern data other than those in which the average value of the transition time transitions at night (after sunset, after 18:00, etc.) is not held. Therefore, this transition time range can be used when performing this selection.
Further, the average value of the pre-transition states is held as the pre-transition state of the action pattern data from the bedtime device state list collected for a certain period.
Further, it is also possible to determine the bedtime core time, which is the core time, by using this action pattern data.
That is, in the action pattern data created from the bedtime equipment state list collected for a certain period, the time when the state change of the control-target equipment 4 is the smallest may be set as the bedtime core time.
The processing in the updating unit 13 will be described in detail below together with the description of the data stored in the storage unit 14 and the flowchart of FIG.

≪Creation of behavior pattern data and selection of operation device at the start of predetermined control≫
The flow of creating action pattern data and selecting a bedtime operation device that is a predetermined period start operation device will be described with reference to FIG.
The process shown in FIG. 5 starts when the sleeping core time, which is the core time, is reached.
To explain the bedtime core time in detail, in the present embodiment, in a general lifestyle, the time at which the user is sure to be in bed every day is set as a default, for example, it is set at 3:00 am. There is.

As described above, the bedtime core time may be unchanged or may be directly input and set by the user. Further, the behavior pattern data may be analyzed to be automatically updated periodically.
For example, as an example in the case of performing the automatic update, as described above, it is preferable to analyze the action pattern data and store the time when the control target device 4 having undergone the state transition is the smallest as the new sleeping core time.

Next, in step S1, the device state information of the controlled device 4 is acquired.
The information to be acquired is the state of all control target devices 4 at the sleeping core time, the time at which the state has transitioned to that state, and the state before the transition.
Then, in step S2, the acquired information is created as a bedtime device state list managed for each device ID, as shown in FIG.
Then, in step S3, the action pattern data shown in FIG. 4 is created based on the bedtime equipment state list in which the data has been collected for a certain period.

Next, in step S4, a bedtime operation device is selected based on the bedtime device state list.
In this selection, the control target device 4 that has undergone the state transition at the time closest to the bedtime core time is extracted from the bedtime device state list, and the extracted control target device 4 is selected as the bedtime operation device.
In other words, in the present embodiment, the bedtime operating device is selected from the bedtime device state list during the period when the action pattern data is created (updated) and during the same period.
In this selection, the device operated at the latest time (the time closest to the bedtime) is extracted from the bedtime device state list for each day of the data collection period, and the extracted control target device 4 is extracted. Among them, the control target device 4 having the highest appearance ratio is used as the bedtime operating device.

Then, the notification device is selected. The notification device may be set by default, but in the present embodiment, it is assumed that the setting can be changed.
Therefore, in step S5, it is determined whether or not the notification device has been changed, and when it is determined that the notification device has not been changed (step S5: No), the previous notification device is directly used as the notification device in step S6. If the notification device has been set and the notification device has been changed (step S5: Yes), the notification device changed in step S7 is selected and the process ends.

It should be noted that the notification device may be selected by extracting the control target device 4 closest to the changed bed operating device when the bed operating device is changed.
In other words, since all the control target devices 4 are managed in association with the device IDs, if the device IDs are provided with in-home plan information and location information, the selected bedtime operation device and the physical device are controlled. The control target device 4 having the closest target position can be selected as a new notification device.
With this configuration, for example, when the bedroom lighting device 44 is selected as the bedtime operation device by referring to the data such as the floor plan, the floor lamps of the bedroom closest to the lighting device 44 are notified. It can be selected as a device.

In addition, the control target device 4, which is positioned such that the functions of the sleep operation device and the notification device may be used together, is linked with the device ID indicating that the device can be used together, and the device ID can be used together. When the control target device 4 to which the information is attached is selected as the bedtime operation device, it may be configured to be preferentially selected as the notification device. In this embodiment, the lighting device 44 is configured as described above, and thus the lighting device 44 is selected as the bedtime operation device and also as the notification device.
Furthermore, the selection of the notification device may be configured so that the user can directly input the change command.
In this way, the selected action pattern data, the bedtime operation device, and the notification device are stored in the storage unit 14 and used when performing the action pattern following type monitor control.

≪About the flow of behavior pattern tracking type supervisory control≫
The device monitoring control will be described with reference to FIG.
As described above, as one embodiment of the present invention, monitoring control at bedtime will be described with reference to FIG.
In the present embodiment, the behavior pattern tracking type supervisory control is configured by two stages of control, that is, “preparation stage control” and “device monitoring control”.
Specifically, the preparation stage control is the stage of steps S11 to S15, and is the stage until the state monitoring of the bedtime operating device is started. Then, the device monitoring control is a stage from step S16 to step S21, which is a stage after the bedtime operation device is operated.

The behavioral pattern tracking type supervisory control (preparation stage control) at bedtime is started by detecting that the monitoring start time has come and that the control target device 4 has undergone some state change. I shall.
As the monitoring start time, an appropriate time may be set according to the control. It should be noted that this setting is preferably configured so that the user can change it in the device 1.
In this example of the bedtime monitoring control, the monitoring start time is set to 18:00. Then, when the present device 1 detects that the control target device 4 has undergone a state change (that is, the user has operated the control target device 4) after detecting 18:00 by the internal clock, The bedtime behavior pattern tracking type monitor control 6 is started. That is, in order to perform the sleep behavior pattern follow-up type supervisory control, it is necessary to reach a predetermined time and the user is not in the absence state (this is determined by whether or not the controlled device 4 is operated). Is a condition.

When the process starts, in step S11, the state of each control target device 4 at the currently stored sleeping core time is extracted. In the present embodiment, as described above, the sleeping core time is set to 3:00 (am), and therefore the state of each control target device 4 at this time is extracted from the action pattern data.
Next, in step S12, it is determined whether or not the state of the controlled device 4 at the sleeping core time and the current state of the controlled device 4 match by 80% or more.
This is performed by comparing the state of each control target device 4 at the sleeping core time in the action pattern data with the current actual state of each control target device 4 read from the detection unit 12, and performing control in which the states match. This is performed by determining whether the target device 4 is 80% or more.
Based on this determination, it is determined whether or not the user is currently going to sleep.

When it is determined in step S12 that the match is less than 80% (step S12: No), it is determined in step S13 whether a predetermined time has elapsed.
The predetermined time may be set to a sufficient time from the processing start time to going to bed.
When it is determined in step S13 that the predetermined time has elapsed (step S13: Yes), the process ends.
That is, when the state of the controlled device 4 is less than 80% the same as the state of the controlled device 4 at the sleeping core time during this predetermined time, the user's life is not in a normal state, and the sleeping behavior pattern Since it is considered that the necessity of performing the follow-up type monitoring control is low, in this case, the processing is terminated.
In addition, in this embodiment, the state of the controlled device 4 and the state of the controlled device 4 at the sleeping core time are based on "whether the state is less than 80%", but this is an example. The standard may be set in any way.

  In step S13, instead of setting a predetermined time, it may be configured to determine whether or not the bedtime core time has been reached. That is, as described above, the sleeping core time is set to a time at which the user is estimated to be surely sleeping. Therefore, at the sleeping core time, the state of the control target device 4 is the sleeping core time. If there is less than 80% agreement with the control target device 4 at the time, it is highly likely that the user's life is not in a normal state, and it is considered that there is a low need for performing sleep behavior pattern tracking type supervisory control. In this case, the process may be ended.

Then, if it is determined in step S13 that the predetermined time has not elapsed (step S13: No), the process returns to step S12.
That is, until the predetermined time set in step S13 elapses, it is monitored whether or not the state of the controlled device 4 matches the state of the controlled device 4 at the sleeping core time by 80% or more, and the state must match. For example, when the processing is completed and 80% or more of the coincidences are confirmed (step S12: Yes), a "confirmation waiting state" is set in step S14, and in step S15, a lighting device which is a bedtime operation device. The monitoring of the status change of 44 is started.
In this way, steps S11 to S15 are the preparatory stage control, and in step S15, preparation for performing device monitoring control is completed and the operation of the bedtime operating device is awaited.
That is, at the time of step S15, the “control target period” of the claims is started, and in this “control target period”, the lighting device 44, which is a bed operation target device described later, is operated as a trigger. The device monitoring control will be started.

More specifically, since the state of the controlled device 4 at the core sleeping time and the state of the controlled device 4 at the current time match by 80% or more, it can be determined that the user is almost ready to go to sleep. Eventually, the operation of the lighting device 44, which is a bedtime operation device, for determining that the sleep state is finally entered is awaited.
Specifically, the user who is going to sleep detects and recognizes that each controlled device 4 such as a living room-related or a kitchen-related object transits to a state at the sleeping core time (this state is " Waiting for confirmation), and waiting for the lighting device 44 (for example, the lighting device 44 installed in the bedroom), which is a bedtime operation device estimated to be operated most recently at bedtime, to be turned off. Becomes

Next, the device monitoring control from step S16 to step S21 will be executed.
First, in step S16, it is determined whether the operation of the lighting device 44, which is a bedtime operation device, has occurred (whether the lighting device 44 has been turned off).
When it is determined in step S16 that the operation of the lighting device 44, which is a bedtime operation device, has not occurred (step S16: No), it is determined in step S17 whether a predetermined time has elapsed.
For this predetermined time, after the state where the state of the controlled device 4 at the core time of sleep and the state of the controlled device 4 at the current time coincide with each other by 80% or more, it is determined that preparation for sleeping is completed (specifically Suffices to be set to a sufficient time that is assumed before the lighting device 44, which is a bedtime operation device, is operated after the “confirmation waiting state” is set).

When it is determined in step S17 that the predetermined time has elapsed (step S17: Yes), the process ends.
That is, if the lighting device 44, which is a bedtime operation device, is not operated (that is, the lighting device 44 is not turned off) during the predetermined time, the user's life is not in a normal state, and the bedtime behavior pattern following type monitoring is performed. Since it is considered that the need for control is low, in this case, the processing is terminated.
In step S17, instead of setting a predetermined time, it may be configured to determine whether or not the sleeping core time has been reached. That is, as described above, the sleep core time is set to the time at which it is estimated that the user is sure to sleep. Therefore, at this time, the lighting device 44, which is the sleep operating device, is not operated. In this case, it is considered that there is a high possibility that the user's life is not in a normal state and there is a low need for performing sleep-time behavior pattern tracking type supervisory control. Therefore, in this case, the processing may be terminated.

Then, when it is determined in step S17 that the predetermined time has not elapsed (step S17: No), the process returns to step S16.
That is, until the predetermined time set in step S17 elapses, it is monitored whether or not the lighting device 44, which is a bedtime operation device, has been operated, and if not operated, the process is terminated, and if it is operated ( In step S16: Yes) and step S18, the sleeping state is set, and in step S19, monitoring of the state of the entrance lock 43, which is the monitoring target device, is started.
That is, in the present embodiment, the device monitoring control is executed with the operation of the lighting device 44, which is a bedtime operation device, as a trigger.

Next, in step S20, it is determined whether or not the entrance lock 43, which is the monitoring target device, is in the set state (that is, the locked state).
When it is determined in step 20 that the entrance lock 43, which is the device to be monitored, is in the set state (locked state) (step S20: Yes), the process ends.
In this case, since there is no matter to notify the user, the processing is ended as it is.

On the other hand, when it is determined in step S20 that the entrance lock 43, which is the monitoring target device, is not in the set state (locked state), the notification process is performed and the process ends in step S21.
In the present embodiment, when the lighting device 44 is selected as the notification device and the entrance lock 43 is not in the locked state, the user is notified that the entrance lock 43 is not locked by blinking the lighting device 44. To inform.
With such a configuration, the user who is about to go to bed can recognize that he / she has forgotten to put on the front door lock 43.
That is, the user turns off the lighting device 44 in the bedroom in order to sleep, but at this time, if the user forgets to put on the entrance lock 43, the lighting device 44 blinks immediately. As a result, the user who has turned off the lighting device 44 can recognize that he / she has forgotten to put on the entrance lock 43.
As described above, according to the present embodiment, the state of the entrance lock 43 as the monitored device can be recognized without performing a special operation.

The behavior pattern tracking type supervisory control has been described above by taking the control at bedtime as an example.
As described above, in the present embodiment, the state change (light out) of the lighting device 44 set as the bedtime operation device is used as the trigger for starting the device monitoring control.
Therefore, the user can perform the device monitoring without being conscious of it by the turning-off work of the lighting device 44 which is normally performed immediately before going to bed.
In other words, it is not necessary to perform a special operation (for example, operation of the monitoring command switch of the monitoring device) in order to perform device monitoring, and thus the user may forget the operation for performing device monitoring. Disappear.
Further, the notification can be given without disturbing the user's daily activities.
That is, in the above, when the lighting device 44 is operated at bedtime, the state of the entrance lock 43 that is the monitored device is immediately fed back (in the above, when the entrance lock 43 is not in the locked state, the lighting device 44 is blinked. ). Therefore, the state of the monitored device can be fed back before the user goes to bed, and the sleep of the user is not disturbed.

There is also a system that starts device monitoring by a timer at a predetermined time and gives a notification when the monitoring device is not in a set state, but in this system, adjustment cannot be performed due to a difference in bedtime of the user.
In other words, the sleeping time of the user is not necessarily the same time every day, but may be mixed up, but with the timer control, the device monitoring starts uniformly at the same time, so the notification is given before or after the actual sleeping. Possible and inconvenient.
However, in the present embodiment, the device monitoring control is executed by detecting that the bedtime operation device serving as a trigger has been operated (step S16 and subsequent steps in FIG. 6), and therefore the device monitoring control corresponds to the actual bedtime. Monitoring and notification can be performed.

In the above, if it is determined in step 20 that the entrance lock 43, which is the monitoring target device, is in the set state (locked state) (step S20: Yes), the process ends.
That is, in the above, since there is no matter to be notified to the user, the process is ended as it is, but the present invention is not limited to this, and the entrance lock 43 is in the set state (locked state). When the determination is made (step S20: Yes), for example, the crime prevention device may be set, and the fact that the setting has been performed may be notified.
The notification device used at this time may be appropriately selected according to its importance and notification content.

Note that the above is an example, and the processing is shown with the entrance lock 43 as the monitoring target device for the sake of simplicity. However, as the monitored device, a plurality of controlled devices 4 may actually be selected. That is, not only the entrance lock 43 but also a plurality of electric shutters 42, window locks 45, and the like may be selected as the monitoring target devices.
Further, the notification device is not limited to the lighting device 44, and needless to say, another notification method using voice or the like may be selected.

Further, in the present example, both the bedtime operation device and the notification device are the illumination devices 44, but the invention is not limited to this, and the bedtime operation device and the notification device are different control target devices 4. However, the lighting device 44 does not necessarily have to be used.
Furthermore, in the above example, the abnormality notification is performed by blinking the lighting device 44. However, the blinking of the lighting device 44 may be configured to end after a predetermined period of time. The lighting device 44 may stop blinking on condition that the entrance lock 43, which is a monitoring device, is locked. With this configuration, the entrance lock 43 can be reliably locked at bedtime.

In addition, since it is predicted that the action pattern data will greatly differ for each holiday, the day before the holiday, and each day of the week, the action pattern data should be created for each holiday and each day of the week, and the control should be performed more appropriately by performing the control accordingly. You can
Further, in the above example, the sleeping core time is set and the control is executed using the sleeping core time. However, the present invention is not limited to this, and the control target device 4 at the sleeping core time, which is the comparison source. When it is difficult to determine the confirmation waiting state, such as when there are few cases, the determination may be made in consideration of the time and the state before transition.

Further, the behavior pattern tracking type supervisory control can be performed for each floor. The following example is assumed as an advantage of being configured in this way.
For example, when a user lives as a family of a plurality of people, they spend their time in each room on the upper floor before going to bed, but the bedtime may not match for each individual. In such a case, by limiting the target for creating the action pattern data and the range to be monitored to the lower floor, the user who goes up from the lower floor to the upper floor immediately before going to bed can close the entrance lock 43 on the lower floor. It becomes possible to inform about forgetting.

Further, in the above embodiment, the system is configured by one device 1 (home server), but the present invention is not limited to this, and the system is configured by a plurality of computers. Good.
Furthermore, in the above embodiment, the device 1 is configured as a home server, but may be configured by a computer different from the home server. For example, the storage unit 14 may be configured by a database server that can communicate with the home server via the Internet.

As described above, according to the above-described embodiment, the state of the controlled device 4 at a predetermined time point is stored, and the stored state is compared with the current controlled device 4 state. It is possible to recognize whether it is the controlled period or the non-controlled period.
In other words, by setting the predetermined time point to the time (“core time” in the above embodiment) that is in a state in which the predetermined determination is almost certainly performed, the current “period” is changed from the current state of the controlled device. Can be recognized.
Specifically, when the predetermined time point is, for example, “at bedtime”, by comparing the state storage of the control target device 4 at bedtime with the current state of the control target device 4, the current control at bedtime is performed. It is possible to recognize whether or not it is the target period.
Then, when it is recognized that the control target period is reached, the control target device 4 is configured to make a predetermined determination.
The "predetermined determination" corresponds to, for example, determination of the state of the control target device 4 involved in crime monitoring. For example, when it is recognized that the control target period is during bedtime, the locked state of the entrance lock 43, which is the control target device 4, can be determined.
Since it is configured in this way, by simply comparing the behavior of the user (behavior for the control target device 4) at a predetermined time with the current behavior of the user (behavior for the control target device 4), simple and reliable, Predetermined decisions relating to monitoring can be performed.

  In addition, the apparatus 1 statistically shows the state of the control-target device 4 at a predetermined time point from the device state list for a predetermined period of time, which collects the state of the control target device at the predetermined time point during a predetermined period. An updating unit 13 that creates estimated behavior pattern data is provided. In addition, the storage unit 14 that stores the action pattern data, the state of the control target device 4 at a predetermined time point in the action pattern data read from the storage unit 14, and the current state of the control target device 4 By comparison, the process execution unit 11 that determines that the current period is the control target period with a match of a predetermined ratio or more.

With this configuration, it is possible to surely execute control in accordance with the user's action.
That is, the behavior pattern data is created by creating a device status list for a predetermined period of time that collects the status of the control target device 4 at a predetermined time every day according to the device ID, and statistically processing the device status list for the predetermined period. it can. Then, the state of the control target device 4 obtained from this action pattern data is compared with the state of the control target device at the current time point, and when there is a match of a predetermined ratio or more, it is determined that the present is the control target period.
For this reason, it is possible to execute the control more in line with the behavior of the user.
“Statistically estimating the state of the control target device 4 at a predetermined time point from the device state list for a predetermined time period” means, for example, the control target device 4 at a predetermined time point from the device state list collected for a predetermined time period This is to estimate the state of the controlled device 4 at a predetermined time point by taking the average value (busiest value) of the state.
As described above, the behavior pattern of the user is largely reflected in the behavior pattern data. Therefore, by using the behavior pattern data, it is possible to easily and surely perform control according to the behavior of the user.

  Further, the updating unit 13 extracts the control target device 4 operated at the closest time before the predetermined time in the device state list for the predetermined period, and the appearance frequency is the highest among the extracted control target devices 4. The control target device 4 having a large number of items is selected as the operation device at the start of the predetermined control. Further, the process execution unit executes the predetermined determination in the controlled period, triggered by receiving the operation signal of the operation device at the time of starting the predetermined control from the detection unit.

In this way, in the device state list for the predetermined period, the control target device 4 that has been operated at the closest time before the predetermined time is extracted, and the plurality of extracted control targets (for the number of days of the normal data collection period) are extracted. Among the devices 4, the control target device 4 having the highest frequency of appearance is selected as the operation device at the time of starting the predetermined control, and the operation of the operation device at the time of the predetermined control during the control target period is used as a trigger to perform a predetermined determination (for monitoring). It is decided to make such a determination).
Therefore, it is possible to select the operation device at the time of starting the predetermined control according to the user's action pattern, and thus it is possible to easily and reliably perform the control according to the user's action.
Further, the predetermined control start operation device which is the trigger is not a special device but is selected from the control target devices 4 that the user normally uses, and the user operates in the normal life.
However, in the present invention, the operation device at the time of starting the predetermined control is selected from the data according to the behavior of the user, and the control is performed under the AND condition that it is during the control target period. Therefore, the specific (selected) control target device 4 can be provided with a function as a predetermined control start operation device. That is, it is possible to distinguish whether the operation of the specific (selected) control target device 4 is an operation as a trigger or an operation in normal living behavior.
Therefore, the user does not need to consciously perform a special operation, which solves the problem that the user forgets the execution and does not perform the control.

Further, the storage unit 14 selects and stores a monitoring target device as a monitoring target device among the control target devices 4, and the process execution unit 11 receives the operation signal of the operating device at the time of starting the predetermined control. Then, it is determined whether or not the state of the monitored device matches the state stored as the state at the predetermined time point in the action pattern data.
Further, in this storage unit, a notification device to be used for notification of the state is selected and stored from the control target devices 4, and the process execution unit 11 uses the operation signal of the predetermined control start operation device. In response, when the state of the monitored device does not match the state stored as the state at the predetermined time in the action pattern data, the notification device is instructed to transmit the predetermined operation signal.

With this configuration, it is possible to effectively monitor the state of the monitoring target device, and to notify the user when the state does not match the state stored as the state at the predetermined time point, which is preferable. is there.
For example, when the "entrance lock 43" is set as the monitoring target device and the "locked state" is set as the "sleeping" state which is the predetermined time point, if the entrance lock 43 is the unlocked state, A predetermined operation signal can be transmitted to the notification device.
For example, when the “lighting device 44” is set as the notification device, the fact that the lighting device 44 is blinked or the like is controlled to notify that the entrance lock is unlocked.
As described above, in the present invention, the user does not need to consciously perform a special operation and can simply and reliably start monitoring and receive notification of an abnormal state by only performing a normal life. Become.
Further, for example, when the lighting device 44 is operated at bedtime, the state of the entrance lock 43, which is a monitored device, is immediately fed back, so that the user can recognize the state of the monitored device before going to bed, Therefore, the sleep of the user is not disturbed.

Further, at this time, the action pattern data further includes position information associated with the device ID, and the notification device is the operation device of the predetermined control start time selected with reference to the device state list for a predetermined period. The control target device 4 installed at the position closest to the position is preferable because the optimum control target device 4 is automatically selected as the notification device.
Further, at this time, if the time at which the state transition of the control target device 4 occurs is the least in the action pattern data at the predetermined time point, the predetermined time point can be set to a time more suited to the user's action, which is preferable. Is.

The device monitoring control method is executed according to the following flow.
A step of reading the memory of the state of the controlled device 4 at a predetermined time.
Next, a step of acquiring the current state of the controlled device 4.
Next, a step of comparing the state of the controlled device 4 at a predetermined time point with the current state of the controlled device 4.
Next, if the comparison result confirms that the ratio is equal to or more than a predetermined ratio, it is determined that the current control target period is set and that the control target period is set.
Next, a step of confirming the state of the monitoring target device selected from the control target device 4, triggered by receiving a signal from the predetermined control start device selected from the control target device 4 in the control target period.
Next, if the state of the monitored device does not match the predetermined state, the notification device selected from the controlled device 4 is operated in a mode different from the normal mode.
As described above, by executing the above-described flow, it is possible to perform control according to the user's action pattern and to easily and surely monitor the targeted device.
