(Embodiment)
[Monitoring system configuration]
First, the configuration of the monitoring system according to the embodiment will be described. FIG. 1 is a block diagram showing a functional configuration of a monitoring system according to an embodiment.

As shown in FIG. 1, the monitoring system 10 according to the embodiment includes an open / close sensor 20, a motion sensor 25, an information processing system 30, a distribution board 60, a lighting device 70, and a first information terminal. It includes 100 and a second information terminal 110. The information processing system 30 includes a control device 40 and a server device 50. Among the components included in the monitoring system 10, the components other than the server device 50, the first information terminal 100, and the second information terminal 110 are installed in the building 80. The building 80 is, for example, a house such as an apartment house or a detached house, but may be a nursing care facility or a hospital.

In the watching system 10, the user who resides in the building 80 is, for example, an elderly person. A user who normally lives in a building 80 turns on and off a device (in other words, an electric device) installed in the building 80, such as a lighting device 70. That is, if the user normally lives in the building 80, the amount of electricity used in the building 80 will fluctuate to some extent. The information processing system 30 included in the monitoring system 10 uses the electricity usage measurement function of the distribution board 60 to detect fluctuations in the electricity usage in the building 80 to see if the user is living normally. It can be determined whether or not.

When the fluctuation in the amount of electricity used is small, the information processing system 30 determines that some abnormality (for example, an abnormality in the health condition) has occurred in the user, such as the user lying down in the building 80, and provides, for example, a watching service. Notification information for notifying the user that an abnormality has occurred is transmitted to the first information terminal 100 used by the providing business operator. As a result, the operator of the business operator who provides the watching service arranges the visitor to the building 80. Further, the information processing system 30 may directly notify the user's family by transmitting the second notification information to the second information terminal 110 used by the user's family (for example, a family living far away). can.

By the way, the fluctuation of the amount of electricity used in the building 80 becomes small even when the user goes out of the building 80 and is absent in the building 80. Therefore, there is a need for a mechanism that prevents the user from accidentally determining that an abnormality has occurred when the user is out of the building 80.

Therefore, the information processing system 30 uses the detection results of the open / close sensor 20 and the motion sensor 25 provided at the entrance / exit of the building 80 to determine whether or not the user has gone out of the building 80 and is absent. As a result, the monitoring system 10 can improve the accuracy of determining whether or not an abnormality has occurred in the user. Hereinafter, each component included in such a monitoring system 10 will be described.

[Open / close sensor and motion sensor]
First, the open / close sensor 20 and the motion sensor 25 will be described. FIG. 2 is a diagram showing an installation example of the open / close sensor 20 and the motion sensor 25.

The open / close sensor 20 detects the opening / closing of the door 81 installed at the entrance / exit of the building 80, and outputs the first information indicating the detection result. The open / close sensor 20 is a magnetic sensor realized by a magnet attached to one of the door 81 and the door frame 82 and a magnet sensor attached to the other of the door 81 and the door frame 82. The open / close sensor 20 may be a radio wave type sensor realized by an RFID tag attached to one of the door 81 and the door frame 82 and an RFID reader attached to the other of the door 81 and the door frame 82. The specific mode of the open / close sensor 20 is not particularly limited. The door 81 is, for example, a front door, but may be a self-propelled door.

The motion sensor 25 is installed in the building 80 and detects the presence or absence of a person in the detection range. Further, the motion sensor 25 outputs the second information indicating the detection result of the motion sensor 25. The motion sensor 25 is realized by, for example, a pyroelectric sensor that reacts to infrared rays emitted from a human body, but may be an ultrasonic motion sensor or the like. The specific mode of the motion sensor 25 is not particularly limited. In the example of FIG. 2, the motion sensor 25 is installed at the entrance (more specifically, the indoor side of the door frame 82) in the building 80, but it may be installed in the building 80.

[Control device]
The control device 40 is, for example, a HEMS (Home Energy Management System) controller having an energy management function, which is installed in the building 80 and manages the power consumption of the equipment installed in the building 80. Further, the control device 40 acquires the state of the device, controls the device installed in the building 80 (or in the site of the building 80), and the like. The control device 40 is provided by a business operator such as a home appliance maker, for example. The control device 40 is not limited to the HEMS controller, and may be another home controller or a gateway device. The control device 40 includes a control unit 41, a communication unit 42, and a storage unit 43.

The control unit 41 controls the control device 40. The control unit 41 is realized by, for example, a microcomputer, but may be realized by a processor or a dedicated circuit.

The communication unit 42 is a communication circuit for the control device 40 to communicate with the open / close sensor 20, the motion sensor 25, the server device 50, and the distribution board 60. The communication unit 42 is, for example, a wireless communication circuit that performs wireless communication, but may be a wired communication circuit that performs wired communication. The communication standard for communication performed by the communication unit 42 is not particularly limited. The communication unit 42 uses, for example, a local communication network when communicating with the open / close sensor 20, the motion sensor 25, and the distribution board 60, and the Internet or the like when communicating with the server device 50. Wide area communication network 90 is used.

The storage unit 43 is a storage device that stores a control program or the like executed by the control unit 41. The storage unit 43 is realized by, for example, a semiconductor memory.

[Server device]
The server device 50 performs information processing such as determination of whether or not the user has gone out from the building 80 and is absent, and determination of whether or not an abnormality has occurred in the user. The server device 50 is provided by, for example, the home appliance manufacturer, but may be provided by another business operator. The server device 50 includes an information processing unit 51, a communication unit 52, and a storage unit 53.

The information processing unit 51 performs information processing such as determination of whether or not the user has gone out from the building 80 and is absent, and determination of whether or not an abnormality has occurred in the user. Specifically, the information processing unit 51 includes a determination unit 57 and an output unit 58. The information processing unit 51 is realized by, for example, a microcomputer, but may be realized by a processor or a dedicated circuit.

The communication unit 52 is a communication circuit for the server device 50 to communicate with the control device 40, the first information terminal 100, and the second information terminal 110. The communication unit 52 can also communicate with the open / close sensor 20 and the motion sensor 25 via the control device 40. Specifically, the communication unit 52 includes the acquisition unit 55. The communication standard of the communication performed by the communication unit 52 is not particularly limited.

The storage unit 53 is a storage device that stores a program or the like executed by the information processing unit 51. The storage unit 53 is realized by, for example, a semiconductor memory.

[Distribution board and lighting equipment]
The distribution board 60 is a device that measures the amount of electricity used (in other words, the amount of power consumption) in the building 80 for each branch circuit, and transmits the electricity usage information indicating the measured electricity usage to the control device 40. If a device such as a lighting device 70, which is turned on and off by the user's normal life, is connected to the branch circuit, the presence or absence of the user's abnormality can be determined by monitoring the electricity usage information of the branch circuit. can.

The distribution board 60 is an example of a device capable of measuring the amount of electricity used by a device such as a lighting device 70, and the control device 40 is an example of a device other than the distribution board 60 capable of measuring the amount of electricity used by the device. It is also possible to acquire electricity usage information by communicating. Other devices are, for example, smart meters (in other words, watt-hour meters having a communication function).

[First information terminal and second information terminal]
The first information terminal 100 is an information terminal used by a business operator that provides a monitoring service to receive notification information transmitted by the server device 50. The first information terminal 100 is, for example, a stationary information terminal such as a personal computer, but may be a portable information terminal such as a smartphone or a tablet terminal.

The second information terminal 110 is an information terminal used by the user's family to receive the notification information transmitted by the server device 50. The second information terminal 110 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may be a stationary information terminal such as a personal computer.

[Example 1 of operation for determining the presence or absence of a person]
Hereinafter, the operation of determining the presence or absence of a person (user) in the building 80 will be described. FIG. 3 is a flowchart of Example 1 of the operation of determining the presence or absence of a person.

First, the acquisition unit 55 of the server device 50 acquires the first information indicating the detection result of the open / close sensor 20 and the second information indicating the detection result of the motion sensor 25 (S11). The first information and the second information are acquired via the control device 40.

More specifically, the first information is information indicating whether the door 81 is in the open state or the closed state. When the first information is relayed to the server device 50 (acquisition unit 55) by the control device 40, time information (in other words, a time stamp) is added by the control unit 41. The opening / closing sensor 20 may add time information to the first information, or the server device 50 may add time information.

More specifically, the second information is information indicating whether or not there is a person in the detection range of the motion sensor 25. In the following, the state in which the presence of a person is detected by the motion sensor 25 is also described as the state in which the motion sensor 25 reacts. When the second information is relayed to the server device 50 (acquisition unit 55) by the control device 40, time information (in other words, a time stamp) is added by the control unit 41. The time information may be added to the second information by the motion sensor 25, or the time information may be added by the server device 50.

Next, the determination unit 57 determines whether or not a person exists in the building 80 based on the acquired first information and the second information (S12). Further, the determination unit 57 stores the determination result in step S12 in the storage unit 53 (S13). FIG. 4 is a time chart showing an example of a specific determination in step S12.

Note that FIG. 4 shows the relationship between the first information, the second information, and the determination result. In FIG. 4, the first information indicates that the door 81 is in the open state at the high level and that the door 81 is in the closed state at the low level. The second information indicates that there is a person in the detection range of the motion sensor 25 at the high level (the motion sensor 25 detects and reacts to the person), and the motion sensor 25 at the low level. It indicates that there is no person in the detection range of (the motion sensor 25 is not responding).

FIG. 4A is a diagram showing the relationship between the first information, the second information, and the determination result when a person in the building 80 goes out of the building 80 and a person is absent in the building 80. be. As shown in FIG. 4A, when a person in the building 80 goes out, the motion sensor 25 does not respond after the first timing t1 when the door 81 transitions from the open state to the closed state. Here, if the period from the first timing t1 at which the door 81 transitions from the open state to the closed state to the second timing t2 at which the door 81 transitions to the open state is defined as the first period T1, the determination unit 57 determines. The first period T1 can be specified based on the first information. When the second information indicates that the motion sensor 25 is not responding during the first period T1, as shown in FIG. 4A, the determination unit 57 is inside the building 80 during the first period T1. Determine that the person is absent.

FIG. 4B is a diagram showing the relationship between the first information, the second information, and the determination result when a person outside the building 80 enters the empty building 80. As shown in FIG. 4B, when a person outside the building 80 enters the building 80, the motion sensor 25 is set after the first timing t1 when the door 81 transitions from the open state to the closed state. react. Therefore, when the second information indicates that the motion sensor 25 has reacted during the first period T1, as shown in FIG. 4B, the determination unit 57 has a person in the building 80 during the first period T1. Is determined to exist.

FIG. 4C is a diagram showing the relationship between the first information, the second information, and the determination result when a person in the building 80 returns to the building 80 in response to a visitor. As shown in FIG. 4C, when a person in the building 80 responds to a visitor, the motion sensor 25 is set after the first timing t1 when the door 81 transitions from the open state to the closed state. react. Therefore, when the second information indicates that the motion sensor 25 has reacted during the first period T1, as shown in FIG. 4C, the determination unit 57 has a person in the building 80 during the first period T1. Is determined to exist.

As described above, the monitoring system 10 can determine the presence / absence of a person in the building 80 by using the detection results of the open / close sensor 20 and the motion sensor 25 provided at the entrance / exit of the building 80.

In addition, the determination unit 57 can also determine (detect) the person's going out and the person's return home. For example, as shown in FIG. 4A, in the determination unit 57, the motion sensor 25 responds to the second information during the first period T1 immediately after the determination that a person is absent in the building 80. When indicating that the person has not done so, it can be determined that a person has gone out from the building 80.

Further, as shown in FIG. 4B, the determination unit 57 responded to the motion sensor 25 during the first period T1 immediately after the second information was determined that a person was present in the building 80. When indicating that, it can be determined that a person has returned home to the building 80.

In the example of FIG. 4, the determination result is not specified for the period in which the door 81 is open in the first information, but the determination result in this period is the same as the determination result in the period immediately before the period. It may be regarded as the same as the judgment result of the period immediately after the period.

Further, in Example 1 of the operation of determining the presence or absence of a person, it was determined that a person exists in the building 80 when the motion sensor 25 reacts even once in the first period T1. However, it may be a requirement that the motion sensor 25 responds to the first period T1 a plurality of times (in other words, two or more times) to determine that a person exists. As a result, it is possible to prevent the false determination that a person exists. In this way, the determination unit 57 determines the existence or nonexistence of a person based on whether or not the number of times the motion sensor 25 has reacted in the first period T1 is equal to or greater than a predetermined number of times (the predetermined number of times is one or a plurality of times). Just do it.

[Example 2 of operation for determining the presence or absence of a person]
It should be noted that the determination that a person exists in the building 80 in the first period T1 as shown in FIG. 4B is confirmed at the timing when the motion sensor 25 reacts after the first timing t1. On the other hand, as shown in FIG. 4A, it is the second timing t2 that the absence of a person in the building 80 is determined in the first period T1. That is, if there is no reaction of the motion sensor 25 after the first timing t1, the absence is not confirmed until the second timing t2 when the door 81 opens next. Therefore, the determination unit 57 may not be able to provide the determination result of the presence or absence of a person in a timely manner. Therefore, the determination unit 57 may make a determination for the third timing t3 (shown in FIG. 4), which is about several seconds to several tens of seconds after the first timing t1. FIG. 5 is a flowchart of Example 2 of the operation of determining the presence or absence of a person.

In the determination unit 57, the motion sensor 25 reacted during the second period T2 (shown in FIG. 4) from the first timing t1 to the third timing t3 at the third timing t3 before the second timing t2. Whether or not it is determined (S21). The length of the second period T2 is, for example, 5 seconds, but may be about several seconds to several tens of seconds.

When the motion sensor 25 reacts during the second period T2 (Yes in S21), the determination unit 57 determines that a person exists in the building 80 in the first period T1 (S22), and determines the determination result. It is stored in the storage unit 53 (S23). On the other hand, if the motion sensor 25 does not respond during the second period T2 (No in S21), the determination unit 57 determines that no person is present in the building 80 during the first period T1 (No). S24), the determination result is stored in the storage unit 53 (S25).

In this way, the determination unit 57 may confirm the presence / absence determination at the relatively early third timing t3. In this case, it is preferable that the motion sensor 25 is arranged in the vicinity of the door 81 so that the motion sensor 25 reacts as soon as possible after the door 81 is closed when there is a person in the building 80.

The determination unit 57 monitors the second information of the motion sensor 25 until the second timing t2 after determining the absence at the third timing t3 (in other words, after storing the determination result in the storage unit 53). Then, it may be further determined whether or not the motion sensor 25 has reacted during the period from the third timing t3 to the second timing t2 (S26).

If the motion sensor 25 reacts during this period (Yes in S26), the determination unit 57 modifies the determination result in the first period T1 to the determination result that a person exists when the motion sensor 25 reacts. (S27). That is, the determination unit 57 stores the determination result stored in the storage unit 53 when the second information indicates that the motion sensor 25 has reacted during the period from the storage of the determination result to the second timing t2. Correct the judgment result that there is a person in the building 80.

On the other hand, if the motion sensor 25 does not respond during the above period (No in S26), the determination unit 57 ends the operation without correcting the determination result.

In this way, the determination unit 57 may determine the determination result at an early stage and immediately correct the determination result when it is considered that the determination result is incorrect.

In Example 2 of the operation of determining the presence or absence of a person, if the motion sensor 25 reacts even once in the second period T2 (or a subsequent period), it is determined that a person exists in the building 80. However, it may be a requirement that the motion sensor 25 reacts a plurality of times in the second period T2 (or a subsequent period) to determine that a person exists. As a result, it is possible to prevent the false determination that a person exists. In this way, the determination unit 57 is based on whether or not the number of times the motion sensor 25 has reacted in the second period T2 (or the subsequent period) is equal to or greater than a predetermined number of times (the predetermined number of times is one or a plurality of times). The existence or nonexistence of a person may be determined.

[Watching operation]
Next, the watching operation using the determination result of the presence or absence of the person (user) as described above will be described. FIG. 6 is a diagram showing an example of a flowchart of the watching operation.

First, the acquisition unit 55 of the server device 50 acquires the electricity usage information indicating the electricity usage in the building 80 from the control device 40 (S31). The acquired electricity usage information is stored in, for example, a storage unit 53. As described above, the control device 40 manages the electricity usage information of the device such as the lighting device 70 connected to the distribution board 60, and provides such electricity usage information to the server device 50. Can be done. It should be noted that the electricity usage information used for watching over the user is not the one that fluctuates regardless of the user's behavior such as the electricity usage information of the refrigerator, but the electricity usage information of the lighting device 70 that the user uses in the building. It is better to have something that fluctuates (turns on and off) only when you are living normally.

Next, the output unit 58 reads out the user's existence / non-existence determination result stored in the storage unit 53 (S32), and the electricity usage information acquired in step S31 and the user's existence / non-existence determination result read out in step S32. Based on the above, it is determined whether or not an abnormality has occurred in the user (S33).

The output unit 58 indicates, for example, that the presence / absence determination result of the user indicates that the user exists in the building 80, and the fluctuation range of the electricity usage amount indicated by the electricity usage amount information is less than a predetermined value. It is determined that an abnormality has occurred in the user (Yes in S33), and notification information is output (S34). Further, in other cases, the output unit 58 determines that no abnormality has occurred in the user (No in S33), and does not output the notification information.

The above notification information is information for notifying the user that an abnormality has occurred. The communication unit 52 transmits the notification information output by the output unit 58 to the first information terminal 100 (S35). The electricity usage information and the determination result of the presence or absence of a person are managed in the storage unit 53 in association with the ID of the control device 40, and the notification information includes the ID of the control device 40.

As described above, the first information terminal 100 is used by the operator of the business operator who provides the watching service. For example, the ID of the control device 40 and the personal information of the user (specifically, name, gender, age, address of the building 80, telephone number, contact of the user's family) are stored in the storage unit (not shown) of the first information terminal 100. If the user information associated with the ID of the second information terminal 110 used by the user's family is stored, the first information terminal 100 will be the ID of the control device 40 included in the notification information. Based on this, it is possible to identify the user who is determined to have an abnormality. Then, the operator who uses the first information terminal 100 can take measures according to the notification information. For example, the operator can deal with the occurrence of an abnormality such as dispatching a visitor to the building 80.

The notification information may be transmitted to the second information terminal 110 in addition to the first information terminal 100 or in place of the first information terminal 100. For example, if the storage unit 53 stores information in which the ID of the control device 40 and the ID of the second information terminal 110 are associated with each other, the communication unit 52 uses the notification information output by the output unit 58 as the user's information. It can be transmitted to the second information terminal 110 used by the family. As a result, the user's family is notified that the user has an abnormality.

If the user's presence / absence determination result is used in the monitoring system 10, it is possible to prevent the user from erroneously determining that an abnormality has occurred when the user goes out of the building 80 and is absent in the building 80. That is, if the determination result of the existence or nonexistence of the user is used in the monitoring system 10, the accuracy of determining whether or not an abnormality has occurred in the user can be improved.

Identify T1 for one period. The determination unit 57 determines that a person exists in the building 80 when the acquired second information indicates that the number of times the motion sensor 25 has reacted during the first period T1 is equal to or greater than a predetermined number of times. The determination unit 57 determines that a person is absent in the building 80 when the acquired second information indicates that the number of times the motion sensor 25 has reacted during the first period T1 is less than a predetermined number of times. do.

Such an information processing system 30 can determine whether or not a person exists in the building 80 based on the number of times the motion sensor 25 reacts in the period from the closing of the door 81 to the opening of the door 81.

Further, for example, the first period T1 includes a second period T2 from the first timing t1 to the third timing t3 before the second timing t2. The determination unit 57 determines that a person exists in the building 80 when the acquired second information indicates that the number of times the motion sensor 25 has reacted during the second period T2 is equal to or greater than a predetermined number of times.

Further, for example, the determination unit 57 indicates that the number of times the motion sensor 25 has reacted during the second period T2 is less than the predetermined number of times, so that the person is absent in the building 80. If it is determined to be present, the determination result is stored in the storage unit 53. The determination unit 57 indicates that the acquired second information indicates that the number of times the motion sensor 25 has reacted during the period from the storage of the determination result to the second timing t2 is a predetermined number of times or more. The determination result stored in 53 is corrected to the determination result that a person exists in the building 80.

Such an information processing system 30 determines in a timely manner whether or not a person exists in the building 80 based on the number of times the motion sensor 25 reacts in a predetermined period immediately after the door 81 is closed. If it is considered that the judgment result is incorrect, it can be corrected.

Further, for example, in the determination unit 57, the number of times the motion sensor 25 reacts during the first period T1 immediately after the acquired second information is determined that a person is absent in the building 80 is less than a predetermined number of times.
