  Human sensors are often used for crime prevention in residences and the like, and are effective in grasping the intrusion and presence of people in residences. By installing in a plurality of places, it is also possible to grasp the situation of entry and exit for each room. However, if the blind spot of the sensor is entered, it cannot be detected even if there is a resident in the residence, and even if it can be detected that there is a resident in the place monitored by the sensor, The fact that it cannot be grasped until it moves smoothly is the limit when it is used for watching the human sensor.

  If one acceleration sensor is attached to a resident to be watched over, it is effective for detecting the operation, but it is impossible to grasp where the resident is in the residence.

  The present invention has been made to cope with such a problem, and is intended for elderly people who need to watch the living situation, and effectively combines a human sensor and an acceleration sensor. An object of the present invention is to provide a resident watching device, a resident watching program, and a resident watching method for watching behavior.

A second estimating means for estimating a resident's movement; and the second estimating means generated for the resident during the time in which the resident is in a certain place estimated by the first estimating means. From the estimated operation (including when the operation can not be estimated), the resident of behavior or condition, or determining means for determining at least one is occurring events that occurred at the residence of the resident, in that it comprises It is a characteristic resident watch device.

  In the present invention, data detected from both the human sensor installed in the residence of the resident to be watched over and the acceleration sensor worn by the resident are received, and the occupants are combined by combining information estimated from these sensors, respectively. It is possible to collect information on more specific living conditions related to residents, which is difficult to judge from data from only one of the human sensor and acceleration sensor. .

  In addition, the residence which is the subject of the present invention includes, in addition to apartment houses such as detached houses and condominiums, facilities such as nursing care facilities and hospitals where the residents who are subject to watching are substantially inhabited. It is. The acceleration sensor worn by the resident is not limited to a dedicated device having only an acceleration sensor, and may be provided in a device having other functions. The resident's “behavior” determined in the present invention includes, for example, the behavior that the resident is cooking or eating, and the resident's “state” includes, for example, the resident's bathroom. For example, an event that occurred in a resident's residence is an event that someone other than the resident invaded the residence. To do.

  Further, the present invention provides a storage means for storing an address for notifying information relating to a resident to be watched over, and an action or a state of the resident who has determined that the determination means has occurred, or a residence of the resident. A transmission means for reading an address for notifying information about the resident from the storage means and transmitting a notification addressed to the address when the generated event falls under a predetermined rule; It can also be.

  If comprised in this way, at the time of emergency that the resident fell and the person other than the resident invaded the dwelling, it is possible to promptly notify the absence family or the person in charge of the care care center. In addition, it is possible to give relief to a family member who is away by notifying information on daily living conditions such as a resident having a meal or taking a bath.

  In addition, the present invention provides storage means for storing the behavior or state of the resident determined to be caused by the determination means, or an event occurring in the resident's residence as information on the living status of the resident. When receiving an access from a terminal operated by an information viewer who has an authority to view information on the living status of the resident, the information on the living status of the resident stored in the storage means is read out to the terminal. And a transmission means for transmitting.

  If comprised in this way, it will become possible for these persons to confirm the information regarding the living condition of a resident including the past by setting browsing authority to the person in charge of an absence family, the care care center, etc.

  Further, according to the present invention, the determination means includes the second estimation means in a time zone in which the first estimation means estimates that a resident is not in a residence because human sensor data is not detected. However, it is possible to determine that the resident is in a residence by estimating some motion in the resident's residence from acceleration sensor data detected during the time period.

  If comprised in this way, even if a resident is in the residence, even if it enters the blind spot of the human sensor, if the data from the acceleration sensor can be detected, it is determined that the resident is in the residence. It becomes possible.

  Further, according to the present invention, even if the determination means estimates that the first estimation means estimates that the resident is in a residence, the second estimation means is resident by the first estimation means. If the acceleration sensor data is not detected at the estimated time when there is a person and the movement in the residence of the resident cannot be estimated, it is determined that an intruder other than the resident has entered the residence. Also good.

  With this configuration, even if the human sensor confirms that the person is in the residence, if the data from the acceleration sensor cannot be detected, the resident should not be in the residence, so the resident is in the residence. It is possible to determine that the person is not.

  The present invention can also be specified as a resident watching program provided in the resident watching device according to the present invention.

A resident watching program according to the present invention is a resident watching program for watching a resident's living situation in a residence using a human sensor and an acceleration sensor, and is a person installed in a resident's residence on a computer. A reception step of receiving human sensor data identified by the detection time detected by the sense sensor and acceleration sensor data identified by a detection time detected by the acceleration sensor worn by the resident; and received in the reception step The first estimation step for estimating the whereabouts of the resident at a certain time from the human sensor data at the time of detection and the acceleration sensor data at the time of detection received at the reception step indicate the time of occurrence. A second estimation step for estimating the movement of the identified resident, and a time for which the resident estimated in the first estimation step is in a certain location. Oite, wherein the resident operation estimated by the generated second estimation step for (including the case where operation can not be estimated), the resident of behavior or condition, or events that have occurred in the residence of the resident least A resident watching program characterized by causing a determination step to determine that one has occurred.

  In addition, the resident watching program according to the present invention is based on a predetermined rule in which the resident's behavior or state determined to have occurred in the determination step, or an event that has occurred in the resident's residence is stored in a computer. If applicable, execute a transmission step of reading from the storage means for storing the address for notifying the address for the resident who watches over the address for notifying the address for the resident and transmitting the notification addressed to the address. It can also be made to feature.

  In addition, the resident watching program according to the present invention may cause the resident's behavior or state determined to have occurred in the determination step, or an event occurring in the resident's residence to the computer.

  Embodiments for carrying out the present invention will be described below in detail with reference to the drawings. In addition, although the following description demonstrates the example which applies this invention to the elderly person who lives alone, a specific system configuration, a resident's action etc. which can be judged by this invention are the things at the time of implementing this invention. It shows an example and the present invention is not limited to such an embodiment. For example, the present invention is also suitable for introduction to a nursing care facility where a large number of elderly people live, and for application to a plurality of elderly people.

  FIG. 1 shows an overview of an embodiment of the present invention. In the present invention, a human sensor is installed in a house in which a resident such as an elderly person to be watched lives, and the resident is provided with a pendant or the like equipped with an acceleration sensor. Data that is detected at the time of detection by the human sensor and the acceleration sensor is collected in a server PC that is installed in the residence via an access point or the like and that corresponds to the resident monitoring device according to the present invention.

  In the server PC, the location of the resident at a certain time is estimated from the human sensor data that is detected by the human sensor, and from the acceleration sensor data that is detected from the acceleration sensor, Estimate the behavior of the resident whose occurrence occurred. Then, in the time when the resident is in a certain place estimated from the human sensor data, the behavior of the resident, the state of the resident, or the residence from the movement of the resident that occurred at that time estimated from the acceleration sensor data It is determined that an event occurred in the person's residence.

  When information on the living conditions of the resident estimated or determined in this way is stored in the server PC, and a person with viewing authority such as a person in charge of a care center or an absence family accesses the server PC via the Internet It is possible to browse the stored information. In addition, when the resident's action or the like determined in the server PC is urgent information that the resident has fallen in the bathroom or a person other than the resident has entered the residence, for example, the server A warning mail or the like is transmitted to a notification destination such as an absence family registered in the PC.

  In FIG. 1, the server PC installed in the resident's residence corresponds to the resident monitoring device according to the present invention, but the present invention is not limited to such a configuration. The human sensor data and acceleration sensor data are relayed to other servers installed in the management center etc. via the Internet. Another server that is executed by the server and installed in the management center or the like may be configured to correspond to the resident monitoring apparatus according to the present invention.

  Further, the data communication path between the human sensor, the acceleration sensor, the access point, and the server PC is not limited as shown in the example of FIG. 1, and the communication line connecting each of them is either wireless or wired. Alternatively, data received from human sensors or acceleration sensors at a plurality of access points may be collected by a device such as a coordinator and transmitted to the server PC.

  The arrangement of the human sensor installed in the residence is not particularly limited, but as shown in the example of FIG. 2, if the human sensor is installed in a plurality of locations of the residence, for example, in each room, In addition to being in a residence, it is also possible to estimate which room you are in. Since the human sensor data is specified at the time of detection, if the total of the human sensor in which room reacts is counted, as shown in the example of FIG. Can be estimated.

  The method for the resident to wear the acceleration sensor is not particularly limited. For example, the resident should be equipped with an acceleration sensor and watch the pendant to be worn by the resident so that the resident can always wear it. And it is sufficient. Although the type of the acceleration sensor is not particularly limited, it is preferable to use a three-axis acceleration sensor in order to accurately grasp the occupant's movements, thereby enabling the residence such as standing, sitting, walking, and falling. It becomes possible to estimate a person's action.

  It should be noted that both the human sensor data and the acceleration sensor data need to be specified at the time of detection of the data, but the method of giving the detection time is not particularly limited. The data given the detection time by the sensor main body may be transmitted to the access point, or the detection time may be given by the access point or coordinator receiving the data from the sensor main body.

  In addition, in the server PC, it is preferable that the acceleration sensor data is received in a state as close to real time as possible. However, the data received in real time from the sensor body is temporarily stored in the access point or coordinator, and at a predetermined timing. The data may be configured to be transmitted to the server PC.

  FIG. 4 shows an example of the configuration of the resident monitoring apparatus according to the present invention. In FIG. 4, the server PC 10 corresponds to the resident monitoring device according to the present invention. However, the server PC 10 may be installed in the residence of the resident to be monitored, or from a PC or the like set as the residence As described above, it may be installed in a management center or the like that can receive data via the Internet or the like.

  The server PC 10 uses a computer such as a personal computer (PC) equipped with an auxiliary storage device such as a CPU, main memory, HDD, etc., and includes a human sensor data receiving unit 11, an acceleration sensor data receiving unit 12, a resident behavior, and the like. A determination unit 13, a human sensor data storage unit 14, an acceleration sensor data storage unit 15, a living situation information storage unit 16, a user information storage unit 17, a browsing request reception unit 18, and a warning notification unit 19 are provided.

  Of these, the human sensor data receiving unit 11, the acceleration sensor data receiving unit 12, the resident behavior determination unit 13, the browsing request receiving unit 18, and the warning notification unit 19 are all functionally specified. Thus, an application program corresponding to the function of each unit is called from the auxiliary storage device such as the HDD to the main memory, and the CPU performs arithmetic processing, thereby realizing the corresponding function.

  In addition, the human sensor data storage unit 14, the acceleration sensor data storage unit 15, the living situation information storage unit 16, and the user information storage unit 17 are each assigned a predetermined storage area of an auxiliary storage device such as an HDD. Is not required to be physically provided in one computer. Any part or all of them can be used as long as they can function in the same manner as one computer, such as a computer that is different from a computer that executes the application program described above, or that is provided in another computer such as a database server.

  The access points 20 and 30 are communication devices that relay the data detected by the human sensors 21 to 23 and the acceleration sensor 31 to the server PC 10, respectively. It is good also as installing the coordinator 40 which is a communication apparatus to aggregate. Although the human sensors 21 to 23, the acceleration sensor 31 and the access points 20 and 30, the access points 20 and 30 and the coordinator 40 or the server PC 10, and the communication line between the coordinator 40 and the server PC 10, wireless communication is generally used. It is also possible to use wired communication for part or all of it.

  As the administrator terminal 50, a terminal such as a PC that can be connected to a network, which is operated by a person in charge of the care center or the like, is used. The administrator terminal 50 is connected to the server PC 10 via a network such as the Internet, and can browse information stored in the server PC 10 and receive notifications from the server PC 10 by e-mail or the like.

  As the user terminal 60, a terminal such as a mobile phone or a PC that can be connected to a network and is operated by a family member who is a resident who is watching over is used. The user terminal 60 is connected to the server PC 10 via a network such as the Internet, and can browse information stored in the server PC 10 and receive notifications from the server PC 10 by e-mail or the like.

  Based on the above configuration, the flowchart of the process of receiving the human sensor data and the acceleration sensor data of FIG. 5, the flowchart of the process of determining the behavior of the resident who is the watching target from these data of FIG. The processing flow by the resident monitoring apparatus according to the present invention will be described using an example of determining the resident's behavior or the like shown in 7 to 10.

  The flowchart in FIG. 5 corresponds to the processing executed by the human sensor data receiving unit 11 and the acceleration sensor data receiving unit 12 in FIG. 4, and shows a processing flow for receiving human sensor data and acceleration sensor data. Yes.

  The communication path through which the server PC 10 receives data detected by the human sensors 21 to 23 and the acceleration sensor 31 is not particularly limited, but these sensors detect the coordinator 40 or the access points 20 and 30. When the detected data is received (S01), the human sensor data in which the detection time detected by the human sensor is specified is stored in the human sensor data storage unit 14 (S02), and the detection time detected from the acceleration sensor is specified. The obtained acceleration sensor data is stored in the acceleration sensor data storage unit 15 (S03).

  In FIG. 4, the human sensor data receiving unit 11 and the acceleration sensor data receiving unit 12 are described so as to receive data detected by the sensors through different paths. It is shown that the sensor data and the acceleration sensor data are received, each is configured to be identified and stored, and these data are received together from one communication path via the coordinator 40, The server PC may be configured to determine and store each data.

  The flowchart in FIG. 6 corresponds to the processing executed by the resident behavior etc. determination unit 13 and the warning notification unit 19 in FIG. 4, and the behavior of the resident who is the target of monitoring from the human sensor data and the acceleration sensor data. The flow of the process which judges is shown.

  The timing at which the resident behavior determination unit 13 and the warning notification unit 19 execute the processing shown in this flowchart is not particularly limited, and the human sensor data and the acceleration sensor are processed according to the processing flow shown in FIG. In a state where the data is stored in the human sensor data storage unit 14 and the acceleration sensor data storage unit 15, the resident behavior determination unit 13 may be periodically activated to execute such processing. Such processing may be executed in parallel with the processing flow shown in FIG. 5 at the timing of receiving sensor data or acceleration sensor data.

  First, from the human sensor data specified by the human sensor data receiving unit 11 (when the detection time received by the human sensor data receiving unit 11 and stored in the human sensor data storage unit 14 is specified). The presence location of the resident at a certain time is estimated using the time specified from the time of detection (including the case where the human sensor data is read and used) (S11).

  Here, the time at which the resident's whereabouts are estimated is not necessarily limited to when the human sensor data is detected. For example, the time when the data is intermittently detected from the human sensor installed in a room. It can be assumed that the occupant is in the room for the entire band. Moreover, about the time slot | zone when data are not detected from all the human sensitive sensors installed in the residence, it can also be estimated that the resident is not in the residence and is going out.

  Next, from the acceleration sensor data identified by the detection time received by the acceleration sensor data receiving unit 12 (the person identified by the detection time received by the acceleration sensor data receiving unit 12 and stored in the acceleration sensor data storage unit 15 Including the case where sensory sensor data is read and used), the operation of the resident whose generation time is specified is estimated using the time specified from the detection time (S12).

  Motions estimated from acceleration sensor data can include standing, sitting, walking, falling, etc., but not only motions that occur at a temporary point, such as falling, but acceleration sensor data are approximate. If the state that is being continued, the standing position is continuing, the state where the acceleration sensor data is changing at a certain rate continues, the walking is continuing for that time, As described above, an operation in which the occurrence time can be grasped as a certain time zone is also included. In addition, about the time slot | zone which has not received acceleration sensor data, a resident's operation | movement cannot be estimated.

Subsequently, the resident's behavior is estimated from the motion estimated from the acceleration sensor data generated for the resident at that time (including the case where the motion cannot be estimated) during the resident's location where the estimator is estimated from the human sensor data. Alternatively , it is determined that either a state or an event occurring in the resident's residence has occurred (S13). Examples of actions, states, and events determined here will be described below with reference to FIGS.

  FIG. 7 is an example of a living state when the resident is in the residence. Assume that it is estimated from the human sensor data that the location of the resident for each time zone transitions to the kitchen, the living room, and the bathroom. In each time zone, the acceleration sensor detects data continuously or intermittently, and the behavior of the resident estimated from the acceleration sensor data changes from standing to sitting in each time zone. Suppose that it was estimated.

  From the above situation, if it is estimated that the resident's action is standing at the time when the resident is estimated to be in the kitchen, the resident's action at that time is “cooking”. You will be able to judge. Similarly, if the movement of the time estimated to be in the kitchen is estimated to be the sitting position, the behavior of the resident at that time can be determined to be “mealing”. As described above, according to the present invention, it is possible to determine not only the resident's whereabouts and actions but also more specific behavior such as “where the resident is doing”.

  FIG. 8 shows an example where the resident is in a residence and a fall occurs. Assume that it is estimated from the human sensor data that the resident's whereabouts for each time zone change from living room to kitchen. In each time zone, the acceleration sensor detects data continuously or intermittently, and the resident's movement estimated from the acceleration sensor data changes from sitting to standing and standing from 12: 00 to 12: Suppose that it was estimated that a fall occurred at some time between 10.

  From the above situation, it is not only that the resident has fallen, but the resident's whereabouts are estimated to be the kitchen from the human sensor data during that time, so the resident can be judged to have “tumbled in the kitchen” Thus, such information may be notified to the absence family by a warning mail or the like. As described above, according to the present invention, it is possible to determine not only an operation that has occurred in a resident, but also a more specific state such as “where the operation has occurred”.

  FIG. 9 shows an example of a case where the resident is in the house but moves to a place where the human sensor becomes a blind spot from the middle and the human sensor data is no longer detected. Since the data from the human sensor is no longer detected after 11:30, it is determined that the resident has gone out only with the human sensor data, but the data from the human sensor is no longer detected. At a later time, the acceleration sensor continuously or intermittently detects data, and the motion during that time changes to walking, sitting, and so on, and then falls.

  From the above situation, although no data is detected from the human sensor, the resident is in a place where the data of the acceleration sensor can be detected, that is, in a place where the blind sensor of the human sensor is located. In addition, it is possible to determine the state of “falling in a blind spot”, and such information may be notified to an absence family by a warning mail or the like. As described above, according to the present invention, it is possible to determine a resident's state that cannot be detected only from the human sensor data based on the combination with the acceleration sensor data.

  FIG. 10 shows an example where a person other than the resident invades the residence while the resident is away from the residence. It is estimated that the resident is not in the residence and is absent during the time period when the data from the human sensor is not detected, and that the resident has returned to the residence after the time when the data starts to be detected. become. Here, it is assumed that the state in which the data from the acceleration sensor is not detected continues at the time when the data from the human sensor is detected.

  From the above situation, the fact that the data from the acceleration sensor is not detected means that the movement of the resident cannot be estimated, that is, the resident is estimated not to be in the residence, and is detected by the human sensor. It is possible to determine the event that occurred in the residence that is not the resident but a person other than the resident, that is, a person other than the resident has entered the residence. The notification may be made by, for example. As described above, according to the present invention, it is possible to determine an event that has occurred in a resident's residence, which cannot be determined from human sensor data alone, by a combination with acceleration sensor data.

As shown in the above example, when it is determined that any one of the behavior or state of the resident or the event occurred in the residence of the resident (S13), the determined behavior or the like is It is determined whether a predetermined rule that requires a warning is met (S14). If the action requires a warning, the warning notification unit 19 is activated, and the e-mail address of the person in charge of the absence family or the care care center who is the notification destination is read from the user information storage unit 17 and read. An e-mail address is set as the destination, and a warning e-mail regarding the resident's behavior and the like is transmitted to the administrator terminal 50 and the user terminal 60 (S15).

  In the present invention, the e-mail transmitted in this case is not limited to the e-mail for warning. For example, information on daily activities such as a resident having a meal or taking a bath is provided. It may be transmitted for the safety of the absence family.

  Regardless of the necessity of warning, the determined behavior of the resident is written in the living situation information storage unit 16 as information on the living situation of the resident (S16). When a person in charge of the care center or absence family who wants to browse these information accesses the server PC 10 from the administrator terminal 50 or the user terminal 60, the browsing request reception unit 18 is activated and the user information storage unit 17 is referred to. When the browsing authority is confirmed by password verification or the like, information on the requested living situation is read from the living situation information storage unit 16 and transmitted to the administrator terminal 50 or the user terminal 60.

  The processing by the resident behavior etc. determination unit 13 and the warning notification unit 19 described above is repeatedly executed until the monitoring is terminated for reasons such as system maintenance, resident outing or leaving for a long time (S17).
