  Hereinafter, a life scene specifying system 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  A life scene specifying system 1 according to an embodiment of the present invention is installed in a computer communication network 10 (hereinafter simply referred to as a communication network 10), a server 100 installed in a care center C, and a house H as shown in FIG. The access sensor 211, the current sensor 212, the distribution board 220, the device 230, and the life scene specifying device 290 are configured.

  The communication network 10 is configured by the Internet, for example. The communication network 10 may be a LAN (Local Area Network) or a public line network.

  The server 100 installed in the care center C includes a display unit such as an LCD (Liquid Crystal Display). The server 100 receives information representing a life scene of a user who lives in the house H, for example, a single person living alone, from the life scene specifying device 290 via the communication network 10, and displays the life scene represented by the received information. Display on the display. The staff working at the care center C confirms the safety of the user based on the life scene displayed on the display unit of the server 100, and performs care for the user according to the confirmation content. The life scene will be described in detail later.

  The entrance / exit sensor 211 is a human sensor installed at an entrance of a room R provided in the house H. The entry / exit sensor 211 determines that the user has entered / exited the room R when sensing the user, and outputs an entry / exit signal indicating the entry / exit of the user to the life scene specifying device 290. The entrance / exit sensor 211 is an open / close sensor that detects the opening / closing of a door installed in the room R. When the opening / closing sensor detects the opening / closing of the door, the entrance / exit sensor 211 determines that the user has entered / exited the room R. It may be output to the device 290.

  The current sensor 212 is connected to a power line L that supplies power from the distribution board 220 to the device 230 installed in the room R or used in the room R. The current sensor 212 measures the current flowing through the power line L and outputs a measurement signal representing the measured current value to the life scene specifying device 290. The distribution board 220 distributes the power supplied from the power system E such as an electric power company to the devices 230 via the power line L.

  The device 230 is a generic name for one or more equipment devices installed in the room R and one or more electronic devices used in the room R. Here, the equipment includes, for example, lighting, a ventilation fan, an air conditioner (hereinafter referred to as an air conditioner), and an IH (Induction Heating) cooking heater. In addition, the electric device includes a rice cooker, a microwave oven, a dryer, a vacuum cleaner, a washing machine, and a television set. The device 230 operates using electric power supplied from the distribution board 220 via the power line L.

  The life scene specifying device 290 specifies the user's life scene based on the input / output signal output from the input / output sensor 211 and the measurement signal output from the current sensor 212, and provides information representing the specified life scene to the care center C. To the server 100.

  Here, the life operated by the user is categorized into a plurality of types of life patterns for each scene (that is, a life scene) characterized by an action performed by the user or an event that occurs in the user (hereinafter referred to as a life event). it can.

  Specifically, the life event includes an exit event that the user leaves the room R, an entrance event that the user enters the room R, a cleaning event that the user cleans, a cleaning event that the user performs laundry, Including a meal event that the user sleeps, a sleep event that the user sleeps, and an abnormal event that the user's health condition deteriorates, the user is injured, or the user dies.

  The life scene characterized by the entrance event includes a scene where the user is present in the room R (hereinafter referred to as an “in-room scene”), and the life scene characterized by the exit event is a scene where the user is out ( Hereinafter, it is referred to as an outing scene). This outing scene includes a scene where the user is lost outside the room R (hereinafter referred to as a lost scene). The occupancy scene includes a normal scene characterized by an abnormal event and an abnormal scene characterized by a normal event other than the abnormal event. Normal scenes include cleaning scenes, laundry scenes, meal scenes, and sleep scenes characterized by cleaning events, laundry events, meal events, and sleep events. The cleaning scene, the laundry scene, the meal scene, and the sleep scene refer to a scene that the user is cleaning, a scene that is being washed, a scene that is being eaten, and a scene that is sleeping. Abnormal scenes include scenes where the user is in poor health, scenes where the user is injured, or scenes where the user is dead.

  A life scene specifying device 290 that specifies that the user's life scene is one of the above-described life scenes includes a CPU (Central Processing Unit) 290a, a ROM (Read Only Memory) 290b, and a RAM (Random) as shown in FIG. Access Memory) 290c, hard disk 290d, first communication circuit 290f, second communication circuit 290g, 7SEG (SEGment) display component 290i, and operation button 290j.

  The CPU 290a performs overall control of the life scene specifying device 290 by executing software processing according to a program stored in the ROM 290b or the hard disk 290d. The RAM 290c temporarily stores information (that is, data) to be processed when the CPU 290a executes the program.

  The hard disk 290d stores a table (that is, a table) that stores various types of information (that is, data). The living scene specifying device 290 may include a flash memory instead of the hard disk 290d.

  The first communication circuit 290f performs serial communication of data between the input / output sensor 211 and the current sensor 212 connected via a serial line. The second communication circuit 290 g communicates data with the server 100 connected via the communication network 10.

  The 7SEG display component 290i displays various codes such as an error code in accordance with the signal output from the CPU 290a. The operation button 290j inputs a signal corresponding to a user operation.

  When the life scene specifying device 290 is activated, the CPU 290a of the life scene specifying device 290 uses the hardware shown in FIG. 2 to detect the occurrence of an exit event and the occurrence of an entrance event, as shown in FIG. Start running. As a result, the CPU 290a functions as a signal acquisition unit 291, an action specifying unit 292, an event detection unit 293, and a life scene specifying unit 295 as shown in FIG. 4, and functions as a storage unit 294 in cooperation with the hard disk 290d. .

  The storage unit 294 stores an operation state table as shown in FIG. This operation state table includes operation state information indicating whether or not each device is operating in columns corresponding to the microwave oven, IH cooking heater, rice cooker, vacuum cleaner, and washing machine included in the device 230, respectively. , Information indicating the time when the operation state last changed (hereinafter referred to as the last change time) is stored.

  When the execution of the event detection process shown in FIG. 3 is started, the signal acquisition unit 291 in FIG. 4 determines whether or not the first communication circuit 290f in FIG. 2 has received the input / output signal (step S01). At this time, when it is determined that the first communication circuit 290f has not received the input / output signal (step S01; No), the signal acquisition unit 291 repeats the process of step S01.

  If it is determined in step S01 that the first communication circuit 290f has received the input / output signal (step S01; Yes), the signal acquisition unit 291 acquires the input / output signal from the first communication circuit 290f, and then, for example, OS ( The current time is acquired from the Operating System, and the acquired time is set as the acquisition time of the input / output signal. Thereafter, the event detection unit 293 similarly acquires, for example, the current time from the OS and reads information representing the first time stored in the storage 230. Thereafter, the event detection unit 293 determines whether the acquired current time is the time when the first time represented by the read information has elapsed from the time when the input / output signal is acquired (that is, the acquisition time). It is determined whether or not (step S02). The first time is set in advance to a time longer than the time normally required for the user who lives in the house H to operate any of the devices 230 after passing through the entrance of the room R.

  If it is determined in step S02 that the first time has not elapsed since the acquisition time (step S02; No), the operation specifying unit 292 in FIG. 4 is acquired by the signal acquisition unit 291 from the current sensor 212 in FIG. Based on the measured signal, the operation states of a plurality of devices included in the device 230 are specified, and it is determined whether or not at least one of the specified operation states has changed from the previously specified state (step S03).

  Here, when none of the devices 230 is operating, the current waveform measured by the power line L is a sine wave as shown in FIG. Next, when the IH cooking heater included in the device 230 is operated, a current waveform as shown in FIG. 6B is synthesized with the current waveform shown in FIG. On the other hand, when the air conditioner included in the device 230 is operated, a current waveform as shown in FIG. 6C is synthesized with the current waveform shown in FIG. That is, the characteristics of the current waveform synthesized with the sine wave in FIG.

  For this reason, the storage unit 294 associates information that identifies the device included in the device 230 with information that represents the feature amount of the current waveform that is combined with the current waveform of the power line L when the device operates. I remember it. The feature amount of the current waveform includes the frequency, phase, and level of a harmonic component (for example, a current component having a frequency of 1 kHz to 20 kHz) extracted from the current waveform.

  Here, the signal acquisition unit 291 in FIG. 4 acquires the measurement signal received by the first communication circuit 290f, and represents information indicating the current value represented by the acquired measurement signal and the acquisition time of the measurement signal. The process of associating information with each other and storing it in the storage unit 294 is executed in parallel with the event detection process of FIG. For this reason, the operation specifying unit 292 determines the power line L from the storage unit 294 based on the current values represented by the plurality of measurement signals acquired up to a predetermined time before the current time and the acquisition times of the measurement signals. The current waveform of the flowing current is specified, and the harmonic component is extracted from the specified current waveform. Thereafter, the action identifying unit 292 extracts a feature amount from the extracted harmonic component using wavelet transform. In addition, as a method of detecting a harmonic component, those skilled in the art can use known methods including the method described in Japanese Patent No. 4400610, for example.

  After that, the operation specifying unit 292 compares the feature amount extracted from the current waveform with the feature amount represented by the information stored in the storage unit 294, and the device and the operation that started the operation based on the comparison result Identify the device that has finished (that is, the device whose operating state has changed). As a method for identifying a device that has started operation and a device that has ended operation, a person skilled in the art can use a known method including the method described in Japanese Patent No. 4400610, for example.

  If it is determined in step S03 in FIG. 3 that the operating state has not changed (step S03; No), the above processing is repeated from step S02. If it is determined in step S03 that the operating state has changed (step S03; Yes), the operation specifying unit 292 acquires the current time from the OS, and sets the acquired time as the time when the operating state has changed. Next, the operation specifying unit 292 stores information indicating the time in the last change time column of the operation state table in FIG. 5 and includes columns included in the operation state table and included in the device 230. Operation state information storage processing for storing information representing the operation state of the device is executed in the corresponding column (step S04). Thereafter, the event detection unit 293 determines that an entry event has occurred (step S05). As shown in FIG. 7 (a), when the user enters the room R, the user usually passes the entrance / exit of the room R at the time t1 and before the first time Tout elapses (for example, from t2 to t4). This is because the operating state of the device 230 changes in order to operate any of the devices 230.

  If it is determined in step S02 of FIG. 3 that the first time has elapsed from the acquisition time (step S02; Yes), the event detection unit 293 determines that an exit event has occurred (step S06). As shown in FIG. 7B, when the user leaves the room R, the user normally uses the room R during the first time Tout after passing through the entrance / exit of the room R at time t1. This is because the operation state of the device 230 does not change because the device 230 is not operated. Since the first time is used to determine whether or not the user has gone out of the room R, the first time is also referred to as an outing determination grace time.

  After step S05 or step S06 in FIG. 3, the event detection unit 293 associates information representing the detection result of the event with information representing the detection time of the event and stores it in the storage unit 294. Is executed (step S07). Thereafter, the above process is repeated from step S01.

  In parallel with the execution of the event detection process, the CPU 290a of the life scene specifying device 290 starts executing the life scene specifying process as shown in FIG. Thereby, the CPU 290a functions as an information output unit 296 in addition to the signal acquisition unit 291, the action specifying unit 292, the storage unit 294, the event detection unit 293, and the life scene specifying unit 295 in FIG. 4.

  Here, since the life scene is characterized by a life event, if the user's life pattern categorized based on the life scene is different, the pattern of the device 230 used for the event by the user (hereinafter, the operation pattern of the device 230). May be different). For example, in the cleaning scene, the washing scene, and the meal scene, the correlation that the vacuum cleaner, the washing machine, and the HI cooking heater, the rice cooker, and the microwave oven are used in the vacuum cleaner event, the laundry machine event, and the meal event, respectively. There is. On the other hand, in the outing scene, the sleep scene, and the abnormal scene, the user does not operate the device 230 or there are few, so that the operation patterns of the device 230 are common or poor. For example, if the user operates the television and goes out, sleeps, or loses consciousness while the lighting is on, the operating state of the television and the illumination does not change or hardly changes. That is, the user will not or hardly operate the device 230 while going out, sleeping, and losing consciousness.

  Therefore, the storage unit 294 of FIG. 4 stores an operation pattern table as shown in FIG. The operation pattern table of FIG. 9 includes information representing life events that characterize life scenes, columns corresponding to microwave ovens, IH cooking heaters, rice cookers, vacuum cleaners, and washing machines included in the devices 230. Are stored in association with motion pattern information indicating whether or not is used in the life event (that is, whether or not it is operated). Specifically, one action pattern is individually associated with each of the meal event, the selection event, and the cleaning event, whereas one action pattern is associated with the sleep event, the abnormal event, and the outing event. Are associated in common.

  In addition, the frequency at which events occur varies from time to time. For example, events occur more frequently during the day than at night. For this reason, the storage unit 294 in FIG. 4 stores a second time table as shown in FIG. The second time table includes information indicating a time zone, information indicating a start time of the time zone, information indicating an end time of the time zone, and an event that occurs in the time zone when the device 230 is operated. A plurality of pieces of information indicating the second time, which is the time from when the operation is performed again, to each other, are stored. Since the second time is a time threshold value used for determining whether or not the living scene is an abnormal scene, it is also referred to as an abnormal determination grace period.

  When the execution of the life scene specifying process of FIG. 8 is started, the life scene specifying unit 295 of FIG. 4 indicates the time when the event detection unit 293 detects a room entry event from the storage unit 294 (hereinafter referred to as a room entry event detection time). Information representing information and a time at which an exit event is detected (hereinafter referred to as an exit event detection time) are read out. Next, the living scene specifying unit 295 determines whether or not the entry event detection time represented by the read information is later than the exit event detection time, so that the current user is in the room R. It is determined whether the room is present (step S11).

  When it is determined in step S11 that the user is currently in the room R (step S11; Yes), the life scene specifying unit 295 specifies that the user's life scene is an in-room scene (step S11). S12). Next, based on the operation state of the device 230 specified by the operation specifying unit 292 in FIG. 4, the life scene specifying unit 295 includes, for example, a cleaning scene, a laundry scene, a meal scene, a sleep scene, and an abnormal scene. A detail specifying process for specifying a life scene classified in more detail than the room scene is executed (step S13).

  Specifically, first, the event detection unit 293 in FIG. 4 reads the operation state information stored in the operation state table in FIG. Next, the event detection unit 293 searches the operation pattern table in FIG. 9 for operation pattern information that matches the read operation state information, and is represented by information associated with the searched operation pattern information. Detect life events. Thereafter, the life scene specifying unit 295 specifies the life scene characterized by the detected life event as a life scene classified in detail.

  As a specific example, as shown in FIG. 9, the occurrence of a laundry event, a cleaning event, and a meal event based on the operating states of a washing machine, a vacuum cleaner, and a microwave oven, an IH cooking heater, and a rice cooker, respectively. Are detected respectively. Further, based on the occurrence of the laundry event, the cleaning event, and the meal event, the detailed life scene is specified as the laundry scene, the cleaning scene, and the meal scene. Similarly, as shown in FIG. 9, none of the washing machine, the vacuum cleaner, and the microwave oven, the IH cooking heater, and the rice cooker are used in the sleep event, the abnormal event, and the exit event. For this reason, it is detected that a sleep event or an abnormal event has occurred based on an operating state in which none of these devices is operating, and based on the detection result, the life scene is either a sleep scene or an abnormal scene. Identified. This is because the outing scene is not included in the occupancy scene specified in step S12.

  After step S13 in FIG. 8, the life scene specifying unit 295 determines whether the specified life scene is a sleep scene or an abnormal scene, or is neither a sleep scene nor an abnormal scene (that is, a laundry scene, a cleaning scene, and Whether it is a meal scene or the like) is determined (step S14). At this time, if it is determined that the specified life scene is a sleep scene or an abnormal scene (step S14; Yes), the life scene specifying unit 295 determines that the operation state of the device 230 is the last from the operation state table of FIG. Information representing the last change time which is the changed time is read (step S15). Next, the life scene specifying unit 295 acquires the current time from the OS (step S16). Thereafter, the life scene specifying unit 295 searches the second time table in FIG. 10 for information representing the time zone including the current time, and the second time associated with the information representing the searched time zone. Is read (step S17).

  Thereafter, the life scene specifying unit 295 determines whether or not a second time has elapsed from the last change time represented by the information read in step S15, based on the current time acquired in step S16. (Step S18). At this time, if it is determined that the second time has elapsed from the last change time (step S18; Yes), the life scene specifying unit 295 specifies that the life scene is an abnormal scene (step S19). As shown in FIG. 11A, normally, when the user operates the device 230 at time t4, the user re-operates the device 230 before the second time Tab elapses (for example, at time t5). As shown in (b), when the re-operation is not performed even after the second time Tab has elapsed from time t4, the user's health has deteriorated to the extent that the device 230 cannot be operated, or the user has been injured. Or because of the high probability of death.

  In step S18 of FIG. 8, when the living scene specifying unit 295 determines that the second time has not elapsed since the last change time (step S18; No), the living scene is included in the normal scene. (Step S20).

  If it is determined in step S11 that the user is not currently in the room R (step S11; No), the life scene specifying unit 295 specifies that the user's life scene is an outing scene (step S21). ). Next, the life scene specifying unit 295 acquires the current time as in step S16 (step S22). Thereafter, the living scene specifying unit 295 determines whether or not a third time has elapsed from the detection time of the last leaving event read in step S11 (hereinafter referred to as the last outing time) based on the current time ( Step S23).

  Here, the third time is the time required for the user to enter the room again without getting lost after leaving the room. For this reason, when it is determined that the third time has elapsed since the last outing time (step S23; Yes), the living scene specifying unit 295 specifies that the living scene is a lost child scene included in the outing scene (step S23). S24). If it is determined in step S23 that the third time has not elapsed since the last outing time (step S23; No), the above process is repeated from step S11.

  After step S19, step S20, and step S24, or when it is determined in step S14 that the identified life scene is neither a sleep scene nor an abnormal scene, the information output unit 296 in FIG. 2 is output to the second communication circuit 290g of FIG. 2 (step S25), and the second communication circuit 290g sends the output information to a server installed in the care center C of FIG. To 100. Thereafter, the above process is repeated from step S11. In step S25, if the identified life scene is an abnormal scene or a lost scene, the information output unit 296 may pose a message indicating that the safety of the user needs to be confirmed or the life of the user is in danger. The server 100 may output a warning message such as being displayed together with the life scene information, and display the life scene represented by the received information and the received message.

  In the present embodiment, the entrance / exit sensor 211 has been described as being installed at the entrance / exit of the room R and detecting the entrance / exit of the user into the room R. Further, the life scene specifying device 290 has been described as detecting the occurrence of an entry event and an exit event for the user's room R. Furthermore, based on the detection result of these events and the operating state of the device 230 used in the room R, the life scene specifying device 290 is a room scene in which the user is in the room R. It has been described as specifying whether it is an outing scene that has gone out of the room R.

  However, the present invention is not limited to this, and the entrance / exit sensor 211 may be installed at an entrance / exit such as the entrance of the house H and detect the user's entrance / exit to the house H. In this configuration, the life scene specifying device 290 can employ a configuration that detects the occurrence of a return home event and an outing event for the user's house H. Furthermore, the life scene specifying device 290 determines whether the current life scene is a home scene where the user is in the house H based on the detection result of these events and the operating state of the device 230 used in the house H. In addition, it is possible to adopt a configuration that specifies whether the scene is an outing scene that has gone out of the house H.

  In the present embodiment, the life scene specifying system 1 is configured to include a current sensor 212, and the life scene device 290 specifies the operation state of the device 230 based on the current waveform measured by the current sensor 212 on the power line L. As explained. However, the present invention is not limited to this, and the life scene specifying system 1 includes a voltage sensor, and the life scene device 290 operates the device 230 based on the voltage waveform measured by the voltage sensor on the power line L. A configuration for specifying the state can be adopted.

  According to these configurations, after detecting the occurrence of an exit event based on the duration of operation of the device 230 and the acquisition time when the entrance / exit signal is acquired, the user's operation is performed based on the detection result and the operation of the device 230. Identify life scenes. For this reason, for example, even if the operating state of the device 230 does not change, the user's life scene can be specified more accurately than before based on whether or not the user has left the room.

  Moreover, according to these structures, the in / out signal output from the in / out sensor 211 that detects that the user has entered and exited the room and the voltage of the power line L that supplies power to the device 230 used in the room are detected. The life scene of the user is specified based on the measurement signal output from the current sensor 212 or the current sensor that detects current. For this reason, for example, compared with the case where an exit event is detected based on the signal each output from the several human sensitive sensor installed indoors, an exit event can be detected with few sensors. Thereby, since the number of sensors installed in the room is reduced, the work performed for installing the sensors is facilitated, and the installation cost of the system can be reduced. Also, for example, privacy is less likely to be infringed than when a user's life is monitored by a camera installed indoors.

  The first time is set to be longer than the time required for the user to operate a device 230 such as a lighting or television set in the room R after the user has entered the room. Therefore, according to these configurations, the occurrence of an exit event is detected when the operation of the device 230 at the acquisition time at which the in / out signal is acquired does not change until the first time elapses from the acquisition time. Therefore, it is possible not only to detect the occurrence of an exit event more accurately than before, but also to determine the presence or absence of the user in the room more accurately than before.

  In addition, according to these configurations, when the operation of the device 230 at the acquisition time when the input / output signal indicating the user's input / output is acquired changes before the first time elapses from the acquisition time, Since the occurrence is detected, it is possible not only to detect the occurrence of an entry event more accurately than before, but also to determine the presence or absence of the user in the room more accurately than before.

  The second time is longer than the time that normally elapses from when the user last operated the device 230 until the user re-operates the device 230 when the user's health state is such that the device can be operated. It is set long. Therefore, according to these configurations, when the user is present in the room, if the operation of the device 230 continues longer than the second time, the user's life scene is abnormal in the user's health condition. Therefore, it is possible to specify that the life scene is an abnormal scene more accurately than in the past.

  Further, according to these configurations, when a room entry event is detected and it is specified that the living scene is not an abnormal scene, it is specified based on the operation of the device 230 whether or not the living scene is a sleeping scene. . For this reason, when the user is out, when the user's health condition is abnormal, and when the user is sleeping, although the operating state of the device 230 does not change or hardly changes, Whether or not the life scene is a sleeping scene can be specified more accurately than before.

  The third time is set longer than the time normally required until the user reenters after going out. For this reason, according to these configurations, when the entrance event is not detected even after the third time has elapsed since the exit event was detected, the user's life scene is specified as a lost scene. Therefore, it is possible to specify a living scene while going out in detail and more accurately than in the past. In particular, whether or not a user with dementia is lost (whether or not hesitated) can be specified more accurately than before.
