Description

  The present invention relates to a living situation remote monitoring system and a living situation remote monitoring method for monitoring the usage status of electrical equipment in each residence.

  With the declining birthrate and aging population, the number of elderly households living alone is increasing regardless of whether they are urban, suburban, rural or mountain villages. According to a report from the National Institute of Population and Social Security (http://www.ipss.go.jp/pp-ajsetai/j/HPRJ2008/yoshi.html) The number of “single households” living alone is the largest. Between 2005 and 2030, “single-person households” increased from 14.46 million households (29.5%) to 18.24 million households (37.4%), while “households with couples” were 9.64 million households during the same period. The number of “households consisting of couples and children” will be reduced from 14.65 million to 100.7 million. Moreover, the number of households whose household head is 65 years or older has increased by approximately 5.48 million, and the number of “single households” whose household head is 75 years or older is 2.18 times from 2005 to 2030. Twenty years later, Japan will surely turn into a society where individuals with a high average age act as units.

  In such an era, even if something changes in the physical condition of a single-person household, it is not easy to get to the neighbors. As an alternative, a method has been devised in which a monitoring system is installed using high-tech equipment that uses sensors and communication equipment to detect anomalies. With this monitoring system, various warning mechanisms are provided mainly by security companies and the like, in which a communication device issues a warning and, based on the warning, for example, a local supervisor or ambulance rushes.

  For example, in the service called “Home Security” of Secom (http://www.secom.co.jp/personal/homesecurity/), the customer's house and the control center are connected by a special line, and various sensors are connected to the door. It is installed on a window and detects the opening and closing of the window, and when it detects an abnormality, it provides a mechanism that automatically notifies the company's control center. It can detect a fire and send an abnormal signal to the company as well. Furthermore, if a user feels any danger outside the house, the user can send an emergency signal to the company by pressing the emergency button. In the event of a sudden illness, services such as sending an emergency signal to the company by simply holding a sensor called the pendant “My Doctor” will be provided. The cost is approximately 500,000 yen for construction costs and 5,000 yen for monthly service usage.

  Apart from this, “Mimamori Hotto Line” (registered trademark) service is provided by ZOJIRUSHI CORP., Which transmits the usage status of the electric pot by communication means and notifies the living status. This can be used in such a way that the status of hot water, power on, warming, etc. of an electric pot placed in a single household is sent to the center, and the information is sent by e-mail to a child living in a remote place. is there. When this service is used, for example, when an electric kettle has not been used for several days or has not been used, the usage pattern differs from normal life. It can be estimated that there is some possibility of change or abnormality. The cost of using this service is 5,000 yen for the initial cost and 3,000 yen for the monthly service usage cost.

  On the other hand, it is interposed between the electrical equipment and the power source, and the characteristic amount (current average value, peak average value, peak time difference, Techniques have been proposed for determining electrical devices by determining energization time and peak delay rate (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3). In addition, a method of analyzing the transition of electric power used by an electric device and classifying the electric device into two types of single-use electric device / continuous-use electric device (see, for example, Patent Document 4), and the feature amount of the electric device (average current consumption) Value, change in current consumption, peak value, effective value, crest factor, waveform rate, time constant that is the convergence time of current change, energization time within the period, peak position during current consumption, power supply voltage and current consumption A method of detecting an electrical device using a peak time difference and a power factor (see, for example, Patent Document 5) has also been proposed. In addition, the electrical characteristics of the electrical equipment (average value of consumption current, peak value, effective value, crest factor, waveform rate, time constant, energization time within the cycle, peak position, phase difference between current voltage and consumption current, time difference, There is a detection method (for example, see Patent Document 6) that is specified using a power factor.

  Patent Document 7 describes that it is determined whether or not an abnormality has occurred using the amount of power used for each individual, and notification is given if an abnormality has occurred. The living situation monitoring system of Patent Document 7 is configured such that a server and a client terminal installed on the user's home side are communicably connected via a communication network, and the daily usage situation of the user's power is patterned in the server. Data and means for receiving daily power usage status received from client terminals installed in the vicinity of the user's home and storing them in the database; patterned data and power usage received and stored from client terminals A means for comparing the two data to extract a difference, a means for comparing the extracted difference with predetermined threshold data to determine that an abnormality has been detected when the threshold is exceeded, and a means for detecting the occurrence of an abnormality in advance. Means for notifying a predetermined destination.

  In the case of the aforementioned “Mimamori Hotto Line” (registered trademark) service, it is only necessary to purchase an electric kettle and pay the service usage fee. You can enjoy the same service. However, there is a problem that the living situation of the resident cannot be completely grasped only by using the electric pot. For example, in a household with a coffee maker in addition to an electric kettle, you may use an electric kettle when drinking green tea, or you may use a coffee maker when drinking coffee, even if the electric kettle is not used That's not abnormal. Similarly, an electric kettle is used in the cold winter, but a life without an electric kettle is common in the hot summer.

  If there is a mechanism that can communicate the usage status of all the TVs, refrigerators, air conditioners, electric pots, coffee makers, etc. in the residence to the outside, as in the case of the above electric pots, in summer or winter, or a little Even if your lifestyle changes, you will be able to grasp the details of your lifestyle in a way that doesn't violate your privacy. By using this technology, it is possible to realize a social system that can be rushed to when a problem occurs in a single person without any significant cost. Realization of such a structure is desired.

  In the case of electric power companies, a power consumption measuring device for each household has already been installed, and inspectors regularly go around each household to read the meter, but the meter reading information can be transmitted via the network. If it becomes, realization of the living condition monitoring system of patent document 7 will become easy. However, this living situation monitoring system is based on the premise of monitoring the power usage in the total amount of households as a unit, and knowing the usage status of each electric device such as a pot, microwave oven, TV in the household Can not.

  Patent Document 7 describes that the use start time of a television or radio can be estimated from the total amount of power used by looking at the inrush current pattern and the peak value from the steady current and the width of the peak value. (FIG. 11 of patent document 7). However, according to various research results of device estimation from power usage, it cannot be estimated as easily as the device can be estimated by the peak value of inrush current and its width. Further, in Patent Document 7, since there is no detailed explanation for device estimation, it is unknown, but it is certain that device estimation is not assumed.

  The present invention has been made in view of the circumstances as described above, does not require special housing construction, is not limited to an electric kettle, grasps the usage status of various electric devices in a house, and is abnormal. The purpose is to provide a system that can determine at a remote location that usage has occurred.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 shows a configuration example of a living situation remote monitoring system according to the first embodiment of the present invention. The remote monitoring system includes a home device 2 and a remote monitoring device 1. The in-home device 2 includes a power tap 4 and a transmitter 3. The remote monitoring device 1 receives the operating status of the electrical device 6 from the home device 2 and displays the operating status of the electrical device 6 for each residence.

  The power tap 4 of the in-home device 2 is interposed between the power outlet of the power supply line and the electric device 6. The power tap 4 includes a plug 24, a detection unit 25, an outlet 26, a determination unit 28, a measurement data storage unit 27, and a detection unit ID storage unit 29. The plug 24 of the power tap 4 is inserted into a power outlet in the house and supplies power to the electrical device 6 connected to the outlet 26. A detection unit 25 is disposed between the plug 24 and the outlet 26. A current flows from the power outlet to the electrical device 6 via the plug 24, the detection unit 25, and the outlet 26. The detection unit 25 includes a power meter or an ammeter, and detects the power consumed by the electrical device 6 connected to the outlet 26 or the current flowing through the electrical device 6. The detection unit 25 measures the current consumption or power consumption of the electrical device 6 in units of a predetermined time, and generates a record of a set of the measurement time and the current consumption or power consumption at the measurement time.

  The electric device 6 connected to the outlet 26 is arbitrary, and may be any electric device such as a television, a refrigerator, an air conditioner, a vacuum cleaner, a lighting fixture, an electric kettle, an electric rice cooker, a microwave oven, or a personal computer.

  The determination unit 28 determines the operating state of the electrical device 6 connected to the outlet 26 from the current or power data detected by the detection unit 25. The operating state of the electric device 6 is determined by two states, for example, an operating state in which the current or power consumed by the electric device 6 is greater than or equal to a threshold value, and a non-operating (stopped) state that is less than the threshold value. Alternatively, the three states of stop, standby and operation, and the operation state may be determined in a plurality of stages. The determination unit 28 stores the data detected by the detection unit 25 and / or the measurement data indicating the determined operating state in the measurement data storage unit 27.

  The measurement data storage unit 27 continuously holds measurement data for a fixed time and measurement data at the measurement time. The measurement data storage unit 27 is prepared for each power outlet in the residence. The detection unit ID storage unit 29 stores a detection unit ID that is a code for uniquely identifying the power tap 4 in the residence. The determination unit 28 adds the detection unit ID to the measurement data and transmits the measurement data to the transmitter 3. The power tap 4 and the transmitter 3 communicate with each other by, for example, a power line carrier, a wireless LAN, a low power wireless, or an analog or PHS standard cordless telephone.

  The transmitter 3 includes a transmission unit 22, a residence ID storage unit 21, and a device type storage unit 23. The transmission unit 22 receives the measurement data and the detection unit ID from the power tap 4. The residence ID storage unit 21 stores a residence ID that is a code for uniquely identifying a residence. The residence ID is an identification code given to the transmitter 3, but since one transmitter 3 is usually installed in one residence, it is a code for identifying the residence. The remote monitoring device 1 identifies a residence for each residence ID of the transmitter 3.

  The device type is information representing the type of the electrical device 6 connected to the power tap 4 (more precisely, the detection unit 25). The device type storage unit 23 stores the device type for each power tap 4 that transmits the measurement data and the detection unit ID to the transmitter 3 in association with the detection unit ID. The correspondence between the detection unit ID and the device type may be supplied from the outside through an input / output interface (not shown) or by a storage medium. Alternatively, the type of the electric device 6 connected to the power strip 4 is determined by the power strip 4, and the device type is transmitted from the power strip 4 to the transmitter 3, thereby providing a correspondence between the detection unit ID and the device type. May be. From the observation data sent from the power tap 4, the type of the electric device 6 may be determined on the transmitter 3 side. In order to determine the type of the electrical device 6 connected to the power strip 4 with the power strip 4 or the transmitter 3, various existing methods can be used.

  Research has been conducted to identify the type of the electric device 6 by observing the characteristics of the power consumption waveform of the electric device 6. For example, Matsumoto et al. (References: Mitsutaka Matsumoto, Jun Fujimoto, Tadaho Enomoto: “Examination of a system that analyzes the breakdown of power consumption of home appliances”, Journal of Energy and Resources Vol. 27, No. 4, pp. 49-54) YANAKA et al. (Reference: Akio Tanaka, Chiharu Murakoshi, Hidetoshi Nakagami: “Element decomposition method of household electricity load measurement”, Energy and Resources Society, 12th Energy System and Economic Conference Proceedings pp.91 -94), the power consumption of the entire home is recorded for several hours on a distribution board, and the type of equipment is estimated from the waveform pattern. Although this method requires a lot of time for measurement, there is an advantage that the type of household electrical appliance can be specified universally.

  In addition, Ito et al. (References: Masahito Ito, Toshiyuki Ohtsuki, Satoshi Inoue, Hiroshi Shigeno, Kenichi Okada, Atsushi Matsushita: “Home Appliance Detection Method and Control System Using Characteristics of Power Consumption Waveforms”, Transactions of Information Processing Society of Japan Vol44, No.1, pp.95-105) measures the power consumption waveform of home appliances individually with low-cost hardware at the outlet, extracts the features, and matches them with the feature database. We are doing identification. In this method, attributes such as the average value of current that can be easily calculated with a simple circuit are used as features, and the type and number of home appliances are limited, but the manufacturer name and model number can be found in a relatively short time. There are benefits that can be identified.

  In addition, Iwasa et al. (References: Junji Iwasa, Makoto Iwata, Masayoshi Kai, Hideo Shimazu, “Proposal of Power Saving Platform“ Green Tap ”(4)-Electrical Appliance Identification Method Based on Power Waveform and Ambient Information”, Information Processing Society of Japan The 71st National Convention (March 2009) employs a method of pattern matching at the level by converting the waveform of power consumption of home appliances into feature vectors. In addition, the home appliances are narrowed down by measuring the surrounding environment before and after the change in the power consumption with the sensor node along with the change in the power consumption of the home appliances. For example, it can be estimated that the air conditioner is highly likely to operate if the temperature rises and falls immediately after the power consumption increases rapidly, and that the room light is likely to be lit if the illuminance rises.

  In FIG. 2, the example of the pattern of the power consumption in the time series for every electric equipment 6 is shown. Regarding the pattern of power consumption, according to the above research results, if the same type of electrical equipment 6 (eg, refrigerator) is observed, a certain period of time will be observed even if the manufacturer and model are different. I know to show. Therefore, when the electric equipment 6 connected to the power outlet or the power tap 4 is used to maintain the connection form, the electric equipment 6 can be estimated with practical accuracy.

  The technique for discriminating the electric device 6 corresponds to a general-purpose pattern recognition technique in a broad sense. There has never been an idea to use the technology to discriminate the type of electrical equipment 6 to estimate the operating status of the electrical equipment 6 and use it for detecting and judging anomalies in single-person households in cities and rural areas. . The present invention provides a device for remotely monitoring the operating status of the electrical device 6 by applying this general-purpose pattern recognition technology to a special application. That is, by observing a time-sequential change in the power usage of the electrical device 6, the technology for discriminating the type of the electrical device 6, and the type and operating status of the electrical device 6 are periodically centered (remote) This is a combination of mechanisms that are transmitted to the monitoring device 1) to make an early detection and notification when an abnormality occurs.

  The transmitter 3 of the in-home device 2 shown in FIG. 1 adds the residence ID, the detection unit ID, and the device type to the observation data and the observed time, and transmits it to the remote monitoring device 1 via the communication network 7. As the communication network 7 that connects the in-home device 2 and the remote monitoring device 1, for example, the Internet, a telephone network, a mobile phone network, or a PHS can be used. For example, ADSL (Asymmetric Digital Subscriber Line), cable television (coaxial cable), optical communication, wireless LAN, or ISDN (Integrated Services Digital Network) can be used as a transmission path for accessing the Internet. .

  Note that one determination unit 28 exists for each power outlet. In a general residence, there are usually not only one power outlet but a plurality of power outlets, and therefore there are a plurality of determination units 28. On the other hand, one transmitter 22 exists in one residence. Therefore, when there are a plurality of determination units 28, the transmission unit 22 takes out the detection unit ID storage unit 29 and the determination unit 28 in each power tap 4 in order, and the value of the residence ID storage unit 21. Repeated transmission with the.

  1 includes a receiving unit 11, a control unit 12, a storage unit 14, and a device operation status display unit 13. The receiving unit 11 receives the residence ID, the detection unit ID, the device type, the observation data, and the observed time from the home device 2. The control unit 12 stores the received data in the storage unit 14 as device operation data 15 for each residence ID and detection unit ID. In addition, for each residence ID, the detection unit ID and the device type are associated and stored as owned device information 16.

  When the control unit 12 receives data from the home device 2, the control unit 12 compares the received device information 16 with the received data, and if the received data includes a combination of the detection unit ID and the device type that is not stored in the owned device information 16. For example, the combination of the detection unit ID and the device type is added to the possessed device information 16.

  The control unit 12 displays the device type and the observation data on the device operation status display unit 13 in association with each house ID. The control unit 12 may process the observation data as appropriate. For example, when the observation data is information indicating the time and the operation state or the stop state, the operation start time and the operation end (stop start) time may be displayed.

  The in-home device 2 is installed for each residence, and one remote monitoring device 1 is installed in an organization that manages, manages, or monitors those residences corresponding to one or more residences. For example, one remote monitoring device 1 exists in one village, specifically, one in a government office or fire department. Alternatively, one remote monitoring device 1 is installed in one apartment, for example, one remote monitoring device 1 exists in a manager's room.

  FIG. 3 shows an example of operation status data according to the first embodiment. FIG. 3 shows data in each part of the in-home device 2 shown in FIG. The detection unit 25 detects the power consumption of the electrical device 6 and generates data of the observed time and power consumption. In FIG. 3, the power consumption is 0 watts at time T0, but is changed to 4 watts at time T1. Similarly, the time until time T6 is stored.

  The determination unit 28 generates device type and operation status data from the data of the detection unit 25. In FIG. 3, the device type is an electric rice cooker. The operation status in time series includes operation stop at time T0, operation at time T2, operation at time T4,. . . Is generated as follows. The detection unit ID stored in the detection unit ID storage unit 29 is id13.

  The transmission unit 22 generates data to be transmitted to the remote monitoring device 1. In the example of FIG. 3, generation of a residence ID, a detection unit ID, a device type, a time, and an operation status is shown as data to be transmitted. The residence ID is hid7 in the example of FIG. Data received from the power tap 4 is set in the detection unit ID and the device type, respectively. In FIG. 3, the values “id13”, “electric rice cooker”, “T6”, and “operation” are extracted from the determination unit 28. Then, “hid7” is taken out from the residence ID storage unit 21 and transmitted as a set of “hid7, id13, electric rice cooker, T6, operation”.

  FIG. 4 shows an example in which the operation status is specifically stored in the remote monitoring device 1. Here, it is reported every 10 minutes that the electric pot is in operation.

  FIG. 5 shows an example of the device operation data 15 and the owned device information 16 according to the first embodiment. The possessed device information 16 is composed of a set of records of a residence ID portion and a possessed device list portion. An existing residence ID is stored in advance in the residence ID portion, and zero or more types of electric devices 6 can be stored in the owned device list portion. When the reception unit 11 receives the device operation data 15, a record in which the value of the residence ID part is the same as the value of the residence ID of the device operation data 15 is extracted from the owned device information 16, and the value of the device type of the device operation data 15 However, if it exists in the possessed device list part of the record of the device possession information of the same residence ID, the process ends without doing anything. If the device type value of the device operation data 15 does not exist in the owned device list part of the record of the owned device information 16 having the same residence ID, the device type value of the device operation data 15 is added to the owned device list part. To do. FIG. 5 shows a specific example of the relationship between the transmission unit 22, the reception unit 11, the device operation data 15, and the owned device information 16.

  FIG. 3 shows a specific example up to the point where one record is transmitted to the transmission unit 22, whereas FIG. 5 shows records sent in random order from the transmission unit 22 of various residences. Is stored in the device operation data 15 of the storage unit 14, and the electric device type that first appears for each residence ID is transferred to the owned device information 16.

  The control unit 12 displays the device operation data 15 received by the receiving unit 11 and stored in the storage unit 14 on the device operation status display unit 13 for each residence in a preset time unit. Warning information that makes it possible for a person in charge at a government office, fire department, or condominium manager to recognize that the abnormalities or changes should be visited directly by looking at the display results. It becomes.

  FIG. 6 is a conceptual diagram illustrating an example in which the living situation remote monitoring system according to the first embodiment is applied to a detached house. For example, in the suburbs and depopulated areas, the technology is used to estimate the type of the electrical device 6, which is installed in a single-family house and estimates the usage and operating status of the electrical device 6 for a certain period of time. Prepare a means to communicate with the government office. The power tap 4 is interposed between the power supply line 5 and the electric device 6. Whether the communication network 7 is an optical network, a wireless LAN, a cable television, or other means depends on the situation of an individual system. At the government office, looking at the operating status of the electrical equipment 6 sent from each residence, and finding out that it is in an abnormal operating status, the person in charge asks the residence from the government office and confirms the state inside. That's fine. For example, if the TV has been used every day but suddenly the TV has not been used for many days, you can confirm that something unusual may have happened.

  Of course, you may have gone on a trip, or you might happen to miss watching TV for a few days, or the TV may be broken, so it does not necessarily mean that an abnormal situation has occurred. It will be much more efficient as a government office than going to check the situation every day. Especially in marginal settlements, the daily living situation remote monitoring system is effective because there are not enough people to check the living conditions of all residents every day. Marginal villages are villages where 50% of the population has become 65 years old or older due to depopulation, making it difficult to maintain a social life together.

  Such problems occur not only in marginal settlements but also in urban areas. Recently, it has been said that the number of elderly living alone has increased rapidly in Tama New Town, which was developed in the 1965s, and even in such a large housing complex, the living status remote monitoring of the first embodiment is The effect of introducing the system can be expected.

  FIG. 7 is a conceptual diagram illustrating an example in which the living situation remote monitoring system according to the first embodiment is applied to an apartment house. In the case of an urban apartment house, as shown in FIG. 7, the condominium manager may play the role that the government office played in the example of marginal settlements. The usage status of the electrical device 6 is connected for each residence of the apartment by a wireless LAN, cable TV, a network in the apartment, etc., and the usage status of the electrical device 6 for each residence can be viewed in the manager's room. And if the utilization condition of the electric equipment 6 is abnormal, an administrator should just go to the apartment house to see a state.

  FIG. 8 is a flowchart showing an example of the operation data detection operation according to the first embodiment. The in-home device 2 activates device operation data detection at predetermined time intervals. When the device operation data detection is activated, the detection unit 25 detects the current consumption or power consumption of the electrical device 6 connected to the outlet 26 (step S11). The determination unit 28 determines and stores the operating state of the electrical device 6 from the detected power consumption or power consumption (step S12). Further, the type of the electrical device 6 connected by the above-described electrical device type determination method is determined (step S13). The household device 2 transmits the device operation data 15 from the transmission unit 22 via the communication network 7 (step S14).

  FIG. 9 is a flowchart illustrating an example of an operation of displaying a living situation according to the first embodiment. The remote monitoring device 1 waits to receive the device operation data 15 from the in-home device 2 (Step S21, Step S22; NO). When the receiving unit 11 receives the device operation data 15 (step S22; YES), the control unit 12 extracts the device type from the device operation data 15 (step S23).

  The control unit 12 checks whether or not there is an extracted device type in the record of the retained device information 16 having the same residence ID as the device operation data 15 (step S24). If the extracted device type is not in the owned device information 16 (step S24; NO), the device type is added to the record of the owned device information 16 having the same residence ID as the device operation data 15 (step S25). If the extracted device type already exists in the owned device information 16 (step S24; YES), the device type is not added. In any case, the control unit 12 displays the device operation data 15 on the device operation status display unit 13 for each residence (step S26).

  As described above, according to the living situation remote monitoring system of the first embodiment, the operation status of the electrical device 6 can be displayed at a place away from the residence without being limited to the specific electrical device 6. The in-home device 2 of the first embodiment is not limited to a specific electric device 6 such as an electric pot, but estimates the type of the electric device 6 and then determines the operating status of the electric device 6 It is. If any home appliance is installed in the target residence, there is an effect that the living situation can be estimated from the home appliance. In addition, since it is not necessary to purchase a new home appliance, this is also effective from the viewpoint of diffusion.

  In addition, if some home appliances are installed in the residence to be monitored, it is not a method that significantly infringes privacy like installing a camera, but a general idea of which electrical device 6 is used and when. In view of this, there is an effect that the living state can be estimated from the display of the operating state of the home electric appliance while being within the allowable range of privacy retention.

  Furthermore, the power strip 4 of the first embodiment is configured to connect between an existing power outlet and the electrical device 6, and at present, when the electricity of the electrical device 6 is directly taken from the power outlet, Installation of equipment is completed simply by relaying the power strip 4 according to the invention. Therefore, there is an effect that it does not take time and labor for laying.

  In the first embodiment, the configuration in which the power tap 4 of the in-home device 2 is connected to the power outlet and the plug 24 of the electric device 6 has been described. The power tap 4 may be connected to a residential power line instead of a power outlet, and the wiring of the electrical device 6 may be connected to a terminal or the like. For example, the structure connected to the lighting fixture installed in a ceiling or a wall surface with the switch box provided in a wall surface may be sufficient.

  In addition, the remote monitoring device 1 may determine the operating state and / or the device type. In that case, the transmission unit 22 transmits time series data of current consumption or power consumption, which is measurement data, to the remote monitoring device 1. In the remote monitoring device 1, for example, the control unit 12 determines an operating state and / or a device type.

(Embodiment 2)
FIG. 10 is a block diagram illustrating a configuration example of the living situation remote monitoring system according to the second embodiment. In the second embodiment, a situation (warning situation) in which information for alerting a person who monitors the living situation in the target residence is to be displayed is automatically determined. The living situation remote monitoring system according to the second embodiment includes a warning situation determination unit 18 in the control unit 12 in addition to the configuration of the first embodiment. In addition, the warning condition determination condition 17 is stored in the storage unit 14. Other configurations are the same as those in the first embodiment. In Embodiment 2, it is displayed on the apparatus operation status display part 13 whether it is a warning status for every residence ID.

  The alert condition determination condition 17 in the storage unit 14 is a set of records in which the condition for determining the operation condition to be alerted and the event name to be alerted are set from the operation condition data of the electrical device 6 viewed in time series. One or more are stored. The warning condition determination condition 17 is supplied from the outside through an input / output interface (not shown) or by a storage medium.

  The warning situation determination unit 18 extracts, from the warning situation determination condition 17, one record at a time, which includes a combination of a condition for determining the operating situation to be alerted and the event name to be alerted. Further, the condition for determining the operation status to be warned in the alarm status determination condition record is taken out, and the house-specific ID, the detection unit ID, the estimated time, the type of the electric device 6 and the operation status held in the device operation data 15 are extracted. It is checked whether or not the data consisting of the set meets the judgment condition.

FIG. 13 shows an example of the warning situation determination condition 17. FIG. 13 shows the concept of the determination condition, not the description expression itself of the determination condition, in order to facilitate understanding. In FIG. 13, the following events are listed. When these events occur, it is presumed that some change may have occurred in the lives of the residents of the residence.
“If“ TV ”is in operation” for more than 24 hours ”
"When" stop "of" electric rice cooker "continues for more than 3 days"
"When" stop "of" TV "continues for more than 2 days"
“If“ Ironing ”continues for 3 hours or more”
“When“ in operation ”of“ pot ”continues for more than 2 days”
“If“ in operation ”of“ hair dryer ”continues for more than 1 hour”

  The determination conditions in FIG. 13 do not necessarily accurately indicate that an abnormality has occurred in the living situation. For example, even when “in operation” of “TV” continues for 24 hours or more ”, there may be a case where a normal life is taken from New Year's Eve to New Year. These determination conditions are stored in the warning situation determination condition 17, and the warning situation determination unit 18 extracts the determination condition and executes the determination.

FIG. 12 is a diagram for explaining an example of the operation of the warning situation determination unit 18. In FIG. 12, the determination condition is described by a function named check-rule. For example, the rule “whether or not“ TV ”is in operation for 24 hours or more” is described as a program as shown below.
Check-rule (Whether “TV” is “in operation” for more than 24 hours ”, * Residence ID, * Latest time)
check-if-this-house-has (* house ID, TV)
* result <= check-range (* House ID, * Latest time, 1440, TV, operation)

  This program starts the operation with the residence ID and the latest time given as arguments from the caller. In the description of the program here, an argument with an asterisk (*) in front of a noun represents a program variable. For example, “* house ID” is a variable. The other arguments represent constants. For example, “TV” is a constant.

The function check-if-this-house-has is a function that checks whether the second argument device exists in the first argument residence. It is stored in the possessed device information 16 what kind of electrical device 6 exists in which house. FIG. 12 shows the following example. This indicates that, for example, a house whose house ID is hid2 has an electric rice cooker and a television. To be precise, it is a list of devices that have been “presumed to be possessed” during the process of the present invention.
house-has (hid2, [electric rice cooker, TV])
house-has (hid4, [refrigerator, iron, pot])
house-has (hid7, [electric rice cooker, vacuum cleaner, refrigerator, PC])

  The check-range function is the first argument housing ID, the second argument latest time, the third argument check time, that is, the time specified in the past (how many minutes in this case) If the device of the fourth argument and the state of the fifth argument are given, the designated electrical device 6 is the residence of the residence ID until the designated time from the designated latest time to the designated time in the past. Checks whether the specified state is continued and returns the result. For example, if you ask "whether the TV is in operation for the past hour or not", if it is "in operation" for the past hour, it will return True. Otherwise, it returns False (false value).

FIG. 12 shows the following example. This is a part of the record stored in the device operation data 15, and actually records of various residence IDs and detection unit IDs are stored. In the following example, according to the results measured every 10 minutes for 1 hour and 30 minutes from 13:10 to 14:40, the pot was in operation.
record (hid4, id17, pot, 2009/6/3/13: 10, running)
record (hid4, id17, pot, 2009/6/3/13: 20, running)
record (hid4, id17, pot, 2009/6/3/13: 30, running)
record (hid4, id17, pot, 2009/6/3/13: 40, running)
record (hid4, id17, pot, 2009/6/3/13: 50, running)
record (hid4, id17, pot, 2009/6/3/14: 00, running)
record (hid4, id17, pot, 2009/6/3/14: 10, running)
record (hid4, id17, pot, 2009/6/3/14: 20, running)
record (hid4, id17, pot, 2009/6/3/14: 30, running)
record (hid4, id17, pot, 2009/6/3/14: 40, running)

  The check-range function checks the record between the specified latest time and the specified retrospective time, and checks whether or not the state of the specified electrical device 6 has continued the specified state. .

  As shown in FIG. 11, the warning situation determination unit 18 includes a control circuit and a program memory in which definitions of a check-if-this-house-has () function and a check-range () function are described. The warning condition determination condition 17 is composed of a program memory in which the definition of the check-rule () function is described. In this embodiment, the check-if-this-house-has () function, the check-range () function, and the check-rule () function are described as similar functions. It seems more natural to store it, but logically, the check-rule () function describes a generic rule, whereas the check-if-this-house-has () function or check- Since the range () function is an internal processing function for interpreting and executing the rule, it has a different role.

  When the warning status determination unit 18 determines that the residence of a certain residence ID is in a warning status, the control unit 12 displays that the residence is in a warning status. Specifically, the control unit 12 displays on the device operation status display unit 13 the residence ID determined to be in the alert status, the name of the residence or resident corresponding to the residence ID, and the event name to be alerted.

  In addition, since the condition which uses the electric equipment 6 changes with individuals, you may change the warning condition determination conditions 17 for every residence. Moreover, since the electric equipment 6 to be held varies depending on the residence, the warning situation determination condition 17 may be set by the logical sum of the operation statuses of the plurality of electrical apparatuses 6, or the warning situation determination condition 17 is combined with a plurality of conditions. It may be expressed by a logical operation.

  FIG. 14 is a flowchart showing an example of an operation for displaying a warning status according to the second embodiment. The operation of the warning status display of the second embodiment adds a warning status determination and a warning status display to the living status display of the first embodiment. The operation from step S31 to step S35 in FIG. 14 is the same as step S21 to step S25 in FIG.

  After determining whether or not to add the device type to the owned device information 16 and performing the device type addition process, the warning status determination unit 18 of the control unit 12 reads the warning status determination condition 17. Then, it is determined from the stored device operation data 15 and the received device operation data 15 whether or not there is a warning situation (step S36).

  When it is determined that the warning situation determination unit 18 is in a warning situation (step S37; YES), the control unit 12 displays on the device operation status display unit 13 that the residential area being watched for is a warning situation (step S37). S38). If it is determined that there is no warning situation (step S37; NO), the warning situation is not displayed. In any case, the control unit 12 displays the device operation data 15 on the device operation status display unit 13 for each residence (step S38).

  As described above, according to the living situation remote monitoring system of the second embodiment, it is automatically determined from the device operation data 15 based on the determination condition whether or not it is a warning situation and displayed. As a result, it is not necessary for the operator to look at the device operation data 15 over a certain period of time and make a determination. In addition, the operator does not need to constantly monitor the device operating status.

  In the living situation remote monitoring system according to the second embodiment, it is possible to switch from a fine service and monitoring to a relatively rough service and monitoring by changing the granularity describing the determination condition. For example, a method of creating a judgment condition “every day, always watching TV from 8:15 to 8:30” and being notified if it does not match it is effective for detailed monitoring. However, there are cases where the details are so uncomfortable that they feel uncomfortable, similar to what is monitored by a camera. In the living situation monitoring system of the second embodiment, the determination condition can be changed according to such an object and the situation to be monitored.
