<First Embodiment>
In the first embodiment, the position of the monitoring target is determined by the communication performed between the communication device that sends the usage amount information of the supply target to the management device and the communication device held by the monitoring target. It is an embodiment concerning a system. In each embodiment, "holding" by the watching target means that the holding target is within a predetermined distance from the watching target regardless of whether or not the watching target is moved.
[Configuration and operation]
FIG. 1 is a conceptual diagram showing a configuration of a communication system 401, which is an example of the communication system of the first embodiment.

The communication system 401 includes a communication device 101, a communication device 201, and a management device 301.

The communication device 201 is held by a person or object to be watched over. The holding includes holding by installation or wearing on the person or object to be watched over.

The communication device 201 holds the ID of the communication device 201. Here, ID is an abbreviation for Identifier (identifier). In the following, the notation "ID" refers to an identifier commonly used in the communication system 401.

The communication device 201 emits radio waves in a predetermined radio band including the ID of the communication device 201 to the surrounding space at a predetermined timing. The timing is, for example, an interval of 1 second. Further, the radio band is a radio band that can be received by the communication device 101. The radio band is, for example, a 920 MHz band.

The communication device 101 measures the usage amount of the supply target to be supplied to the user by the user. The supply target is, for example, electric power supplied by an electric company, tap water supplied by a water company, or gas supplied by a gas company.

The communication device 101 sends the measured usage amount and the measurement information including the ID of the communication device 101 to the management device 301 through the communication line 501a at predetermined intervals. The interval is, for example, 30 minutes. As the communication line 501a, for example, a PLC line, a multi-hop line using the 920 MHz band, a wireless telephone line, or a combination thereof can be used. Here, PLC is an abbreviation for Power Line Communication.

The communication device 101 can transmit and receive radio waves in a predetermined frequency band. The frequency band is a frequency band related to radio waves transmitted by the communication device 201. The frequency band is, for example, a 920 MHz band.

The communication device 101 holds the ID of the communication device 201 in advance.

When the communication device 101 receives a radio wave in the frequency band, the communication device 101 acquires an ID included in the reception information and a reception radio wave strength (also referred to as a reception electric field strength) related to the reception. Then, the communication device 101 determines whether the acquired ID is the ID of the communication device 201.

When the communication device 101 determines that the ID included in the received information is the ID of the communication device 201, the communication device 101 determines the position of a person or object to be watched from the received radio wave intensity. The determination is a determination as to whether or not the person or object to be watched is within a predetermined position range. For example, if the person to be watched is a person who should be in a certain building, the determination is a determination as to whether or not the person is in the building. Further, for example, if the object to be watched is an object that should be in a certain building, the determination is a determination as to whether or not the object is in the building.

Detailed examples of the determination will be described later in the sections of [Operation example] and [Processing flow example].

In the following, when the communication device 101 determines that the ID included in the received information is the ID of the communication device 201, the received radio wave strength of the radio wave carrying the received information is referred to as "first strength". To. Further, when the communication device 101 determines that the ID included in the reception information is not the ID of the communication device 201 corresponding to the communication device 101, the received radio wave strength of the radio wave carrying the received information is referred to as "second strength". I will say that. Here, "corresponding to the communication device 101" means, for example, the case where the owner, the manager, the user, or the like of the communication device 201 and the communication device 101 are the same. The above is the same in the following description.

When the communication device 101 determines that the person or object to be watched is not (not) at a predetermined place, the communication device 101 sends a notification A indicating that fact to the management device 301. The A notification includes the ID of the communication device 101 and the ID of the communication device 201.

When the communication device 101 determines that the above-mentioned ID is not the ID of the communication device 201, the communication device 101 determines whether the second strength is equal to or higher than a predetermined threshold value. When the second intensity is equal to or higher than a predetermined threshold value, it means that another radio device similar to the communication device 201 has approached the communication device 101. Then, when the communication device 101 determines that the second intensity is equal to or higher than the threshold value, the communication device 101 sends a B notification indicating that fact to the management device 301. The B notification includes the ID of the communication device 101 and the ID of the communication device.

The communication device 101 is, for example, a smart meter constituting an AMI (Advanced Metering Infrastructure) network. The smart meter is described in Non-Patent Document 1, for example. In that case, the communication device 101 is installed outdoors and can communicate with the HEMS or the like installed in the building managed by the user by the so-called B route. Here, HEMS is an abbreviation for Home Energy Management System. Further, the B route is described in, for example, Non-Patent Document 1.

Further, the radio band used for the B route communication is, for example, a 920 MHz band. Therefore, when the radio wave emitted by the communication device 201 is in the 920 MHz band, the communication device 101, which is a smart meter, can use the communication unit used for the B route communication to receive the radio wave.

When the management device 301 receives the measurement information from the communication device 101, the management device 301 records a set of the usage amount information, the ID of the communication device 101, and the reception time of the measurement information included in the measurement information. Then, the management device 301 performs a predetermined process by using the usage amount information recorded in the past, the ID of the communication device 101, and the information of the reception time set of the measurement information, if necessary. The process is, for example, a process of charging the user for a usage fee corresponding to the usage amount.

The management device 301 communicates with the communication device 101 and other communication devices similar to the communication device 101 (not shown in FIG. 1) through the communication line 501a.

Each of the other communication devices also, like the communication device 101, is a combination of the usage amount information of the supply target and the ID of each of them, which is measured by the user to which each of them is assigned. , "First information") is sent to the management device 301.

In each of the other communication devices, similarly to the communication device 101, the second intensity of the radio wave emitted into the radio space by the communication device other than the communication device associated with the communication device exceeds a predetermined threshold value. In that case, the following is done. That is, each of the above notifies the management device 301 that the second intensity of the radio wave exceeds a predetermined threshold value and the communication device ID included in the received information via the communication line 501a. In the following, the above-mentioned B notification shall also include those notifications sent by each of the other communication devices to the management device 301.

The management device 301 includes the ID of the communication device included in the B notification sent by the communication device 101 and each of the other communication devices described above, the ID of the communication device that sent the B notification, and the time when the B notification is received. Information combined with (hereinafter referred to as "second information") is retained in the database.

In the following, the ID of the communication device will be described as "communication device ID", and the ID of the communication device will be described as "communication device ID", respectively.

When the management device 301 receives the A notification from the communication device 101, the management device 301 searches the second information stored in the database for the second information including the communication device ID included in the A notification. do. Then, when the management device 301 searches for the second information including the communication device ID, the management device 301 identifies the position of the communication device from the communication device ID included in the second information. Here, it is assumed that the management device 301 holds the position information of each communication device. The location information is information representing the correspondence between each communication device ID and the position of the communication device of the communication device ID.

Then, the management device 301 derives the position of the communication device 201 from the position of the specified communication device. The management device 301 also sends a C notification, which is a notification including the location information of the derived communication device 201, to the notification destination 601 through the communication line 501b. The communication line 501b is, for example, a communication line connected to the Internet. Further, the C notification is, for example, an e-mail notification sent to a mobile terminal or a personal computer which is a notification destination. In addition, the user of the notification destination is a person who holds the communication device 201 and watches over the object to be watched over.

It can be assumed that the C notification does not include the position information of the communication device 201.

FIG. 2 is a conceptual diagram showing the configuration of the communication device 101 shown in FIG. 1 and the communication device 101a which is an example of each of the above-mentioned other communication devices.

The communication device 101a includes a measurement unit 121, communication units 116a and 116b, processing units 106a and 106b, a creation unit 111, and a recording unit 126.

The measuring unit 121 measures the utilization amount of the above-mentioned supply target. Then, the measuring unit 121 causes the sequential recording unit 126 to record the measurement information including the usage amount information representing the measured usage amount. The measuring unit 121 is an integrated wattmeter when the supply target is electric power. The measuring unit 121 is an integrated water meter when the supply target is tap water. The measuring unit 121 is an integrated gas meter when the supply target is gas.

The processing unit 106a reads the measurement information recorded in the recording unit 126 from the recording unit 126 at a predetermined timing. Then, the processing unit 106a includes the ID of the communication device 101a read from the recording unit 126 in the measurement information. Then, the processing unit 106a sends the measurement information to the management device 301 shown in FIG. 1 via the communication unit 116a.

Further, the processing unit 106a causes the communication unit 116a to send the information created by the creation unit 111 to the management device 301 shown in FIG. 1 in accordance with the instruction of the creation unit 111.

The communication unit 116a sends the information instructed by the processing unit 106a to the management device 301 shown in FIG. The communication unit 116a also sends the information received from the management device 301 to the processing unit 106a.

The communication unit 116b receives a predetermined radio wave belonging to the same frequency band as the radio wave emitted by the communication device 201 shown in FIG. The radio wave received by the communication unit 116b may be a radio wave transmitted by the communication device 201, or may be a radio wave transmitted by another communication device not shown in FIG.

Then, when the communication unit 116b receives the radio wave, the communication unit 116b obtains the received radio wave intensity of the radio wave. The communication unit 116b also acquires the ID when the ID can be acquired from the radio wave. When the ID can be acquired, the communication unit 116b sends the combination of the received radio wave intensity and the acquired ID to the processing unit 106b.

The processing unit 106b determines whether the ID sent from the communication unit 116b is the ID of the communication device 201 shown in FIG. 1 held by the recording unit 126. The determination is a determination as to whether or not the ID is the ID of the communication device 201, which is a communication device corresponding to the communication device 101a.

When the processing unit 106b determines that the ID is the ID of the communication device 201, the processing unit 106b determines the position to be watched from the first intensity or the time change amount of the first intensity. The determination is a determination as to whether or not the object to be watched is within a predetermined position range. The time change amount is a value indicating the degree of change in the first intensity with the passage of time. The time change amount is, for example, the amount of change of the first intensity per unit time or the slope of the time change of the first intensity.

Detailed examples of the determination will be described later in the sections [Operation example] and [Processing flow example] described later.

When the processing unit 106b determines that the monitoring target is within a predetermined position range, the processing unit 106b does not perform any special operation other than the above.

On the other hand, when the processing unit 106b determines that the monitoring target is not within a predetermined position range, the processing unit 106b causes the creation unit 111 to create notification information. The notification information includes information indicating that the monitoring target is not within a predetermined position range, the ID of the communication device 101a, and the ID of the communication device 201. The notification information is information for performing the above-mentioned A notification.

On the other hand, when the processing unit 106b determines that the ID is not the ID of the communication device 201, which is a communication device corresponding to the communication device 201a, the processing unit 106b determines whether the second intensity is equal to or higher than a predetermined threshold value. Then, when the processing unit 106b determines that the second intensity is equal to or higher than a predetermined threshold value, the processing unit 106b causes the creating unit 111 to create notification information indicating that a communication device other than the communication device 201 is approaching. The notification information includes the ID of the communication device 101a and the communication device ID related to the received information. The notification information is information for performing the above-mentioned B notification.

The creation unit 111 creates notification information according to the instructions of the processing unit 106b. Then, the creation unit 111 sends the created notification information to the processing unit 106a. The processing unit 106a is made to send the notification information to the communication unit 116a to the management device 301 shown in FIG.

The recording unit 126 holds in advance the ID of the communication device 101a and the ID of the communication device 201 shown in FIG.

The recording unit 126 also holds programs and information used by each of the measuring unit 121, the communication units 116a and 116b, the processing units 106a and 106b, and the creating unit 111 to perform the above processing.

The recording unit 126 also records information instructed by each of the measuring unit 121, the communication units 116a and 116b, the processing units 106a and 106b, and the creating unit 111. The recording unit 126 also sends information instructed by each of the measuring unit 121, the communication units 116a and 116b, the processing units 106a and 106b, and the creating unit 111 to any of these destinations in accordance with the instructions.

In each configuration shown in FIG. 1, it is assumed that the electric power required for the operation of each configuration is supplied from a power source (not shown).

Further, although the communication device 101a shown in FIG. 2 includes a measurement unit 121, the communication device of the present embodiment does not necessarily have to include a measurement unit. In the above description of the measuring unit 121, the processing unit 106a, and the recording unit 126 in the communication device of the present embodiment not provided with the measuring unit, "measuring unit 121" is read as "external measuring device".

FIG. 3 is a conceptual diagram showing the configuration of the management device 301a, which is an example of the management device shown in FIG.

The management device 301a is, for example, a server.

The management device 301a includes a communication unit 316a, a processing unit 306, a recording unit 321 and a creation unit 307, and a communication unit 316b.

The management device 301a communicates with the communication device 101 and the above-mentioned other communication device (not shown in FIG. 1) via the communication line 501a shown in FIG.

The communication unit 316a receives the above-mentioned measurement information, A notification, and B notification sent by the communication device 101 and the other communication device. The communication unit 316a sends each of the received measurement information, the A notification, and the B notification to the processing unit 306 in combination with the time when each of them is received.

The processing unit 306 is the first that the recording unit 321 includes the first information that is a combination of the usage amount and the communication device ID and the time when the measuring device is received, which is included in the measurement information sent from the communication unit 316a. Store in the database. The processing unit 306 also includes a second information included in the B notification sent from the communication unit 316a, which is a combination of the communication device ID and the communication device ID and the time when the B notification is received, in the recording unit 321. Store in the second database.

The processing unit 306 performs processing such as billing processing for each communication device ID from the first information stored in the first database.

When the A notification is sent from the communication unit 316a, the processing unit 306 also adds the communication device ID included in the A notification to the communication device ID included in the second information stored in the second database. Determine if there is a match.

Then, when the processing unit 306 determines that the communication device ID included in the second information matches the communication device ID included in the A notification, the second information determined to match. Therefore, the position of the communication device of the communication device ID included in the A notification is specified. The processing unit 306 identifies the position of the communication device from the communication device ID included in the second information determined to match and the position information of the communication device holding each communication device ID. The position information is held in advance by the recording unit 321. A processing example in which the processing unit 306 specifies the position of the communication device will be described later in the section [Processing flow example].

Then, the processing unit 306 causes the creation unit 307 to create the above-mentioned C notification including the information indicating the position of the specified communication device, and sends it to the notification destination via the communication unit 316b.

When the communication unit 316b sends the C notification created by the creation unit 307, the processing unit 306 specifies the notification destination of the C notification to the communication unit 316b.

The notification destination is stored in the recording unit 321.

The processing unit 306 may select a notification destination from a plurality of notification destination candidates related to the C notification stored in the recording unit 321. The processing unit 306 makes the selection as follows, for example.

It is assumed that the recording unit 321 holds two notification destinations, a first notification destination and a second notification destination, for the A notification including a certain communication device ID. The first notification destination is a notification destination for when the user of the notification destination device is at home. The first notification destination is, for example, a personal computer installed in the user's house. The second notification destination is for the case where the user of the notification destination device is not at home. The second notification destination is, for example, the mobile phone of the user.

When the A notification arrives from the communication unit 316a, the processing unit 306 includes the communication device ID that matches the communication device ID included in the A notification from the above-mentioned first database held by the recording unit 321. Read information. The first information is information at the time of reception close to the time of reception of the A notification. The processing unit 306 may read a plurality of first information.

The processing unit 306 determines whether the user is at home or out of the house from the read first information. Then, when the processing unit 306 determines that the user is at home, the processing unit 306 selects the first notification destination as the notification destination of the C notification. On the other hand, when the processing unit 306 determines that the user is out, the processing unit 306 selects the second notification destination as the notification destination of the C notification.

The creation unit 307 creates a C notification according to the instruction of the processing unit 306. The C notification is typically an email notification. The creation unit 307 sends the created C notification to the communication unit 316b.

The communication unit 316b sends the C notification sent from the creation unit 307 to the above-mentioned notification destination through the communication line 501b shown in FIG. 1 according to the instruction of the processing unit 306.

The recording unit 321 holds the ID of the management device 301a and the ID of the communication device 101 connected via the communication line 501a shown in FIG. 1 and the IDs of the other communication devices described above.

The recording unit 321 also holds position information representing the correspondence between the ID of each of the communication device 101 and the other communication device described above and the position of each of the communication device 101 and the other communication device described above.

The recording unit 321 also holds a notification destination for each C notification of the communication device 101 and the other communication devices described above. The notification destination is associated with the communication device ID of each of the communication device 101 and the other communication device described above.

The recording unit 321 further holds the above-mentioned first database and the second database.

The recording unit 321 further holds programs and information necessary for each of the communication unit 316a, the processing unit 306, the creation unit 307, and the communication unit 316b to perform each of the above-mentioned processes.

The recording unit 321 also records information instructed by each of the communication unit 316a, the processing unit 306, the creation unit 307, and the communication unit 316b.

The recording unit 321 also sends information instructed by each of the communication unit 316a, the processing unit 306, the creation unit 307, and the communication unit 316b to any of these destinations in accordance with the instruction.

At least a part of the mounting portion 231 is fixed to the transmitter 226. Then, the mounting portion 231 facilitates the holding of the communication device 201b by a person or an object to be watched over.

FIG. 6 is a conceptual diagram showing the configuration of the communication device 201c, which is an example of the communication device 201b shown in FIG. FIG. 6A is a top view of the communication device 201c. FIG. 6B is a cross-sectional view assuming a case where the communication device 201c is cut along the line 199a.

The communication device 201c includes a transmitter 226c and a mounting unit 231c.

The transmitter 226c is an example of the transmitter 226 shown in FIG.

The mounting portion 231c includes a belt portion 233, a contact portion 232, and a contacted portion 234.

A transmitter 226c is fixed to the belt portion 233.

The belt portion 233 has flexibility and can be wrapped around a attached portion such as a human hand or foot or a rod-shaped portion of an object.

Then, with the belt portion 233 wound around the mounting portion, the surface of the contact portion 232 and the surface of the contacted portion 234 are brought into contact with each other, and the surfaces are pressed against each other with a predetermined surface pressure. The surface and the surface of the contacted portion 234 are fixed with a predetermined strength.

As described above, the communication device 201c is attached to the mounting portion.

For example, one of the contact portion 232 and the contacted portion 234 is one of a pair of hook-and-loop fasteners that can be adhered to each other, and the other of the contact portion 232 and the contacted portion 234 is the other of the surface fasteners.

The contact portion 232 and the contacted portion 234 may be adhesive. Further, when the contact portion 232 and the contacted portion 234 are sticky, it can be assumed that one of the contact portion 232 and the contacted portion 234 does not exist.

The mounting portion may be a portion for attaching to a wristwatch belt or an arm, in addition to the mounting portion 231c shown in FIG.

The mounting portion may further have a structure that can be locked, such as a handcuff. If locked, the communicator can be less likely to be removed from the watch after being attached to the watch.
[Operation example]
Next, a specific example of the operation of the communication device shown in FIG. 1 will be described.

7 and 8 are diagrams showing an example of time change (No. 1) of the position of the communication device 201 shown in FIG. The time changes in the order of FIG. 7 (a), FIG. 7 (b), FIG. 8 (a), and FIG. 8 (b).

The target person 701 shown in FIGS. 7 and 8 is a person to be watched over by a person (not shown). The inside of the building 706 is the position range where the subject 701 should be. Then, the position of the target person 701 is out of the position range when the target person 701 goes out of the building 706. Here, in order for the target person 701 to go out of the building 706, it must pass through the doorway 711. Here, a door, a window, or the like is assumed as the entrance / exit.

In the following, "abnormality" refers to the fact that the object to be watched is outside the specified position range.

Then, the state of the target person 701 becomes even higher when the target person 701 goes out of the site. Here, in order for the target person 701 to go out of the site, he / she must pass through the gate installed at the gate 716.

The communication device 201 shown in FIG. 1 is attached to the target person 701.

A communication device 101 is installed on the site near the gate 716.

FIG. 7A is a diagram showing a state in which the subject 701 is inside the building 706.

The communication device 201 attached to the subject 701 emits radio waves at a predetermined timing. The radio wave passes through the constituent members of the entrance / exit 711 and the wall of the building 706, reaches the communication device 101, and is received by the communication device 101. The constituent members of the doorway 711 are, for example, a door, a window glass, and the like.

The radio wave intensity of the radio wave reaching the communication device 101 is greatly attenuated as compared with the vicinity of the communication device 201. The reason is that the distance from the communication device 201 to the communication device 101 is at least the distance between the communication device 101 and the entrance / exit 711, and the radio waves are attenuated by the components of the entrance / exit 711 and the wall of the building 706.

The communication device 101 acquires the ID of the communication device 201 included in the radio wave. The communication device 101 also determines that the received radio wave intensity of the radio wave (the above-mentioned first intensity) is smaller than a predetermined threshold value (threshold value Th1). In that case, the communication device 101 does not perform any operation other than the above with respect to watching over the target person 701.

FIG. 7B is a diagram showing a state in which the subject 701 opens the doorway 711 and goes out to the site outside the building 706.

The radio wave intensity of the radio wave communication device 101 by the communication device 201 is such that the target person 701 opens the doorway, and the components (door, window glass, etc.) of the doorway and the wall of the building 706 are between the communication device 201 and the communication device 101. It increases when there is no more. Since the time required for the entrance / exit components to disappear between the communication device 201 and the communication device 101 is short, the radio wave intensity increases in a short time. Therefore, the first strength of the communication device 101 increases in a short time.

The communication device 101 determines that an abnormality has occurred in the states of the target person 701 and the communication device 201 due to the increase in the first intensity (first determination). The communication device 101 gives, for example, a notification (first notification) based on the first determination.

The first notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The first notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) included in the communication device 101. In this case, these display units that have received the first notification display information indicating that an abnormality has occurred in the location of the target person 701.

If the increase in the first intensity continues for a certain long time, the communication device 101 may determine that a higher degree of abnormality has occurred in the states of the subject 701 and the communication device 201 (second). Judgment). The communication device 101 gives, for example, a notification (second notification) by the second determination.

The second notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The second notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) provided in the communication device 101. No. In this case, these display units that have received the second notification display information indicating that an abnormality has occurred in the state of the target person 701. If the display unit has already performed the display for which the first notification has been received, for example, the display has a higher warning level than the display.

FIG. 8A is a conceptual diagram showing a state in which the subject 701 on the site approaches the gate 716. The fact that the subject 701 approaches the gate 716 means that the subject 701 is likely to leave the site through the gate of the gate 716. Therefore, the state shown in FIG. 8A has a higher degree of abnormality than the state shown in FIG. 7B.

In the state shown in FIG. 8A, the communication device 201 attached to the subject 701 is near the communication device 101 installed near the gate 716. Therefore, the radio wave intensity of the radio wave emitted by the communication device 201 reaching the communication device 101 is higher than that shown in FIG. 7B. Therefore, the first intensity of the radio wave by the communication device 101 is also large.

When the communication device 101 determines that the first intensity of the radio wave exceeds the threshold value Th2 (third determination), for example, a third notification is given.

The third notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The third notification may be sent to, for example, a display unit (not shown) installed inside the building 706 or in the site, or a display unit (not shown) included in the communication device 101, instead of the notification A described above. No. In this case, these display units that have received the third notification display information indicating that an abnormality has occurred in the state of the target person 701.

If the above-mentioned display unit has already performed the above-mentioned first notification or the second notification, the display is, for example, a notification with a higher warning level.

FIG. 8B is a diagram showing a state in which the subject 701 who has passed through the gate of the gate portion 716 is separated from the gate portion 716 and the building 706.

In the state shown in FIG. 8B, the communication device 201 attached to the target person 701 is away from the communication device 101. Therefore, the first intensity of the reception of the radio wave emitted by the communication device 201 by the communication device 101 is lower than that shown in FIGS. 7 (b) and 8 (a).

When the communication device 201 determines that the first intensity is smaller than the threshold value Th3 (fourth determination), the communication device 201 gives, for example, a fourth notification.

The fourth notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The fourth notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) provided in the communication device 101. No. In this case, these display units that have received the fourth notification display information indicating that an abnormality has occurred in the state of the target person 701.

When the above-mentioned display unit has already performed the above-mentioned first notification, second notification, or third notification, the display is, for example, a display having a higher warning level.

9 and 10 are diagrams showing a time change example (No. 2) of the position of the communication device 201 shown in FIG. The time changes in the order of FIGS. 9 (a), 9 (b), 10 (a) to 10 (c).

The object 702 shown in FIGS. 9 and 10 is an object to be watched by a person (not shown). The position range where the object 702 should be is defined as the inside of the building 706. The position of the object 702 becomes abnormal when the object 702 goes out of the building 706.

The person 703 shown in FIGS. 9 and 10 is a person who enters the building 706 from the outside of the building 706 and takes out the object 702. Here, in order for the person 703 to go out of the building 706 with the object 702, the person 703 must pass through the doorway installed at the doorway 711.

The state of the object 702 becomes further abnormal when the object 702 goes out of the site. Here, in order for the person 703 to go out of the site with the object 702, the person 703 must pass through the gate installed at the gate 716.

The communication device 201 shown in FIG. 1 is stored in the object 702.

A communication device 101 is installed on the site near the gate 716.

FIG. 9A is a diagram showing a state in which the object 702 is inside the building 706.

The communication device 201 stored in the object 702 emits radio waves at a predetermined timing. The radio wave passes through the constituent members of the entrance / exit 711 and the wall of the building 706, reaches the communication device 101, and is received by the communication device 101. The radio wave intensity of the radio wave reaching the communication device 101 is greatly attenuated as compared with the vicinity of the communication device 201. The reason is that the distance from the communication device 201 to the communication device 101 is long, and the radio waves are attenuated by the components of the entrance / exit 711 and the wall of the building 706.

The communication device 101 acquires the ID of the communication device 201 included in the radio wave. The communication device 101 also determines that the first intensity of the radio wave is smaller than a predetermined threshold value (threshold value Th1). In that case, the communication device 101 does not perform any special operation other than the above with respect to watching over the object 702.

FIG. 9B is a diagram showing a state in which a person 703 enters the building 706 and holds an object 702. In the state shown in FIG. 9B, the radio wave emitted by the communication device 201 stored in the object 702 is attenuated by the components (door, window glass, etc.) of the entrance / exit 711 and the wall of the building 706, and the communication device. Reach 101. Therefore, the first intensity of the radio wave by the communication device 101 is smaller than the threshold Th1.

FIG. 10A is a diagram showing a state in which a person 703 holds an object 702, opens an entrance / exit 711, and goes out to a site outside the building 706.

The radio wave intensity of the radio wave communication device 101 by the communication device 201 is determined by the fact that the person 703 opens the doorway 711 and the components (door, window glass, etc.) of the doorway 711 are eliminated between the communication device 201 and the communication device 101. ,To increase. Since the time required for the component of the entrance / exit 711 to disappear between the communication device 201 and the communication device 101 is short, the radio wave intensity increases in a short time. Therefore, the first intensity of the radio wave of the communication device 101 increases in a short time.

The communication device 101 determines that an abnormality has occurred in the states of the object 702 and the communication device 201 due to the increase in the first intensity (first determination). The communication device 101 gives, for example, a notification (first notification) based on the first determination.

The first notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The first notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) included in the communication device 101. No. In this case, these display units that have received the first notification display information indicating that an abnormality has occurred in the state of the object 702.

If the increase in the first intensity continues for a long time to some extent, the communication device 101 may determine that a higher degree of abnormality has occurred in the states of the subject 701 and the communication device 201 (No. 1). Second judgment). The communication device 101 gives, for example, a notification (second notification) by the second determination.

The second notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The second notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) provided in the communication device 101. No. In this case, these display units that have received the second notification display information indicating that an abnormality has occurred in the state of the target person 701. If the display unit has already performed the display for which the first notification has been received, for example, the display has a higher warning level than the display.

FIG. 10B is a conceptual diagram showing a state in which a person 703 on the site approaches the gate 716 with the object 702. The fact that the person 703 approaches the gate 716 means that the object 702 is likely to leave the site through the gate of the gate 716. Therefore, the state shown in FIG. 10B has a higher degree of abnormality than the state shown in FIG. 9B.

In the state shown in FIG. 10B, the communication device 201 attached to the object 702 is near the communication device 101 installed near the gate 716. Therefore, the radio wave intensity of the radio wave emitted by the communication device 201 reaching the communication device 101 is higher than that shown in FIG. 10A. Therefore, the first intensity of the radio wave by the communication device 101 is also large.

When the communication device 101 determines that the first intensity of the radio wave exceeds the threshold value Th2 (third determination), for example, a third notification is given.

The third notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The third notification may be sent to, for example, a display unit (not shown) installed inside the building 706 or in the site, or a display unit (not shown) included in the communication device 101, instead of the notification A described above. No. In this case, these display units that have received the third notification display information indicating that an abnormality has occurred in the state of the object 702.

When the above-mentioned display unit has already performed the display for which the above-mentioned first notification has been received, the display unit performs, for example, a notification with a further raised warning level.

FIG. 10C is a diagram showing a state in which the object 702 that has passed through the gate of the gate portion 716 is separated from the gate portion 716 and the building 706.

In the state shown in FIG. 10C, the communication device 201 stored in the object 702 is away from the communication device 101. Therefore, the first intensity related to the reception of the radio wave emitted by the communication device 201 by the communication device 101 is lower than the state shown in FIGS. 9B and 10A.

When the communication device 201 determines that the first intensity is smaller than the threshold value Th3 (fourth determination), the communication device 201 gives, for example, a fourth notification.

The fourth notification is, for example, the above-mentioned A notification sent to the management device 301 shown in FIG. The fourth notification may be sent not to the above-mentioned A notification, but to, for example, a display unit (not shown) installed inside the building 706 or on the site, or a display unit (not shown) provided in the communication device 101. No. In this case, these display units that have received the fourth notification display information indicating that an abnormality has occurred in the state of the object 702.

When the above-mentioned display unit has already performed the display in which the above-mentioned first notification or the third notification has been received, the display unit performs, for example, a notification in which the warning level is further raised.

In addition, the display unit in the description of FIGS. 7 to 10 outputs information indicating that an abnormality has occurred in the location of the target person 701 by voice, vibration, or the like together with the display or instead of the display. It doesn't matter.

The display unit is, for example, a HEMS installed inside the building 706. Here, HEMS is an abbreviation for Home Energy Management System. When the communication device 101 is a smart meter, it is defined that the communication device 101 communicates with HEMS by the above-mentioned B route (see Non-Patent Document 1). Therefore, when the communication device 101 is a smart meter, the HEMS, which is the display unit, can output the display or the like by communication by the B route.

FIG. 11 shows a communication device for radio waves emitted by the communication device 201, which corresponds to the transition of the state shown in FIGS. 7 (a) to 8 (b) or 9 (a) to 10 (c). It is a conceptual diagram which shows the time change example of the 1st intensity in 101.

The first intensity before the time Tr is the first intensity of the radio wave emitted by the communication device 201 in the communication device 101 in the states of FIGS. 7 (a), 9 (a), and 9 (b). In this state, the radio wave emitted by the communication device 201 reaches the communication device 101 through the components of the entrance / exit 711 shown in FIGS. 7 (a), 9 (a) and 9 (b) and the wall of the building 706. .. Therefore, the first intensity before the time T is larger than the above-mentioned threshold value Th3, but is a relatively low value.

Then, between the time Tr and the time Ta, the entrance / exit 711 shown in FIGS. 7 (a) and 9 (b) is represented by the subject 701 when represented in FIG. 7 (a) and in FIG. 9 (b). Is opened by person 703. As a result, the constituent members between the communication device 201 and the communication device 101 are eliminated, and the first strength increases within a short time. Then, at the transition to the time Ta, the first intensity becomes Th1 or more.

After that, between the time Ta and the time Tb, the state shown in FIG. 7 (b) is changed to the state shown in FIG. 8 (a), or the state shown in FIG. 10 (a) is changed to the state shown in FIG. 10 (b). , Each transition. Between the time Ta and the time Tb, the communication device 201 approaches the communication device 101, so that the first intensity increases.

Then, in FIG. 8A or FIG. 10B, the first intensity becomes the threshold value Th2 or more.

After the time Tb, the first intensity increases until the time Tc when the communication device 201 approaches the communication device 101 closest to the communication device 101, and when the time Tc is exceeded, the communication device 201 and the communication device 101 are separated from each other. Decrease.

Then, when the time Td is exceeded, the first intensity becomes less than the threshold value Th3. The time Td is a time corresponding to the state of FIG. 8 (b) or FIG. 10 (c).
[Processing flow example]

Then, the processing unit 211 determines, as the processing of S102, whether or not the time ΔT1 has elapsed from the end of the processing represented by S101. Here, it is assumed that the processing unit 211 can use the timer.

If the determination result of the processing of S102 is yes, the processing unit 211 performs the processing of S103.

On the other hand, when the determination result by the processing of S102 is no, the processing unit 211 performs the processing of S102 again.

When the processing of S103 is performed, the processing unit 211 determines whether or not to end the processing shown in FIG. 12 as the same processing. The processing unit 211 makes the determination, for example, by determining whether or not the end information is input from the outside. The end information is, for example, due to the power supply from the power source 221 shown in FIG. 5 being stopped.

When the determination result by the process of S103 is yes, the processing unit 211 ends the process shown in FIG.

On the other hand, when the determination result by the processing of S103 is no, the processing unit 211 performs the processing of S101 again.

Next, an example of a processing flow of processing performed by the communication device 101 shown in FIG. 1 will be described.

FIG. 13 is a conceptual diagram showing an example of a processing flow of processing performed by the processing unit 106a of the communication device 101a shown in FIG. This process is a process of sending the above-mentioned measurement information measured by the communication device 101a to the management device 301 shown in FIG.

The processing unit 106a starts the processing shown in FIG. 13, for example, when the power supply is started.

Then, the processing unit 106a acquires the latest measurement information recorded by the measuring unit 121 shown in FIG. 2 in the recording unit 126 as the processing of S201 from the recording unit 126. Here, it is assumed that the measurement unit 121 shown in FIG. 2 sequentially records the measurement information in the recording unit 126.

Then, the processing unit 106a creates the transmission information including the measurement information acquired from the recording unit 126 as the processing of S202.

Then, the processing unit 106a instructs the communication unit 116a to send the transmission information created by the processing of S203 to the management device 301 shown in FIG. 1 as the processing of S203. The communication unit 116a sends the transmission information to the management device 301 according to the instruction.

Then, the processing unit 106a determines, as the processing of S204, whether or not the time ΔT2 has elapsed from the end of the processing of S203. Here, it is assumed that the processing unit 106a can use the timer.

If the determination result of the processing of S204 is yes, the processing unit 106a performs the processing of S205.

On the other hand, when the determination result by the processing of S204 is no, the processing unit 106a performs the processing of S204 again.

When the processing of S205 is performed, the processing unit 106a determines whether to end the processing shown in FIG. 13 as the same processing. The processing unit 106a makes the determination, for example, by determining whether or not the end information is input from the outside. The end information is, for example, due to a stoppage of the supplied power.

When the determination result by the process of S205 is yes, the processing unit 106a ends the process shown in FIG.

On the other hand, when the determination result by the processing of S205 is no, the processing unit 106a performs the processing of S201 again.

FIG. 14 is a conceptual diagram showing an example of a processing flow of processing related to radio waves emitted from a radio device, which is performed by the processing unit 106b of the communication device 101a shown in FIG. In the process shown in FIG. 14, the communication unit 116b shown in FIG. 2 determines the received radio wave intensity of the radio wave having the same frequency as the frequency of the radio wave emitted by the communication device 201 shown in FIG. 1 and the information contained in the radio wave. , It is assumed that the signals are sequentially sent to the processing unit 106b.

The processing unit 106b starts the processing shown in FIG. 14, for example, by starting the power supply.

Then, as the processing of S261, the processing unit 106b determines whether the received radio wave intensity of the radio wave having the same frequency as the radio wave frequency emitted by the communication device 201 shown in FIG. 1 exceeds the threshold value Th6. Here, the threshold value Th6 is a predetermined threshold value for the received radio wave intensity for the processing of S261. The threshold value Th6 is held in advance by the recording unit 126 shown in FIG.

When the determination result by the processing of S261 is yes, the processing unit 106b performs the processing of S262.

On the other hand, when the determination result by the processing of S261 is no, the processing unit 106b performs the processing of S261 again.

When the processing unit 106b performs the processing of S262, as the same processing, is the ID of the source of the radio wave included in the radio wave determined to be yes by the processing of S261 the one of the communication device 201? To make a judgment about.

When the determination result by the processing of S262 is yes, the processing unit 106b performs the processing of S263.

On the other hand, when the determination result by the processing of S262 is no, the processing unit 106b performs the processing of S264.

When the processing unit 106b performs the processing of S263, the processing unit 106b performs the first processing described later with reference to FIG. 15 as the same processing. Then, the processing unit 106b performs the processing of S266.

When the processing unit 106b performs the processing of S264, the processing unit 106b determines whether the ID included in the radio wave is that of another target radio wave as the same processing. The other communication device is a radio device such as the communication device 201 shown in FIG. The other communication device is assumed to be held by a monitoring target of a communication device other than the communication device 101 shown in FIG.

When the determination result by the processing of S264 is yes, the processing unit 106b performs the processing of S265.

On the other hand, when the determination result by the processing of S264 is no, the processing unit 106b performs the processing of S266.

When the processing unit 106b performs the processing of S265, the processing unit 106b performs the second processing described later with reference to FIG. 25 as the same processing. Then, the processing unit 106b performs the processing of S266.

When the processing of S266 is performed, the processing unit 106b determines whether to end the processing shown in FIG. 14 as the same processing. The processing unit 106b makes the determination, for example, by determining whether or not the end information is input. The end information is generated, for example, by stopping the power supplied to the processing unit 106b.

When the determination result by the process of S266 is yes, the processing unit 106b ends the process shown in FIG.

On the other hand, when the determination result by the processing of S266 is no, the processing unit 106b performs the processing of S261 again.

FIG. 15 is a conceptual diagram showing an example of the processing flow of the processing of S263 shown in FIG.

Smart meters, which are such communication devices, are being introduced into homes, and it is expected that the introduction will be completed by the end of 2024 in Japan as a whole (see Non-Patent Document 1). By monitoring with a communication device such as a smart meter that constitutes the AMI network, it becomes possible to provide reliable monitoring at low cost without introducing a new independent system for monitoring.

Further, in an environment where the communication device is a smart meter, the smart meter is introduced in each home, and the smart meter exists in a high density, the following effects can be obtained. That is, the management device of the present embodiment makes it possible to track the position of the monitoring target in a substantially continuous time series by communicating with the communication device held by the monitoring target and the smart meter.
[effect]
As described above, in the communication system of the first embodiment, the communication device determines an abnormality in the position of the monitoring target from the received radio wave intensity (first intensity) of the radio wave emitted by the communication device held by the monitoring target. .. The received radio wave intensity is a value that greatly changes depending on the distance between the communication device and the communication device held by the monitoring target. Therefore, the accuracy of determination regarding the position of the object to be monitored based on the received radio wave intensity is higher than that of the method using GPS described in the section of [Background Technology].

The communication device further causes an abnormality in the position of the monitoring target that the monitoring target goes out of the building, depending on the presence or absence of a member between the communication device installed outside the building and the communication device. Judgment is made based on the change in reception strength. Therefore, the communication device can make a more accurate determination as to whether the object to be watched goes out of the building.

The communication device can make a subdivided determination of the abnormal situation of the position of the monitoring target based on the value of the first intensity and the duration of the value even after the monitoring target goes out of the building. .. Therefore, the person watching over the watching target can grasp the subdivided abnormal situation of the position of the watching target.

When the communication device determines that the position of the monitoring target is abnormal, the communication device notifies the management device of the above-mentioned A including the ID of the communication device as necessary. The management device determines that the communication device or another communication device similar to the communication device is approaching from not only the communication device but also another communication device similar to the communication device (the combination described above). Is collecting. Then, when the management device receives the A notification, the management device sends the C notification indicating that an abnormality has occurred in the position of the monitoring target to the person watching over the monitoring target. In that case, the watcher can know that an abnormality has occurred in the position of the watch target.

The management device may search for the determination information of the communication device ID that matches the communication device ID included in the A notification, and obtain the position of the communication device from the matching determination information in the communication device ID. In that case, the management device sends a C notification including the position information of the position to a person who watches over the target. In that case, the watcher can know the position of the watch target as well as the abnormality of the position of the watch target.

Further, when the communication device is a smart meter constituting an AMI network, the communication system of the present embodiment can inexpensively perform reliable monitoring without introducing an independent new system for monitoring. It will be possible to provide.

Further, in an environment where smart meters are introduced in each home and exist in high density, the following effects can be obtained in addition to the above effects. That is, the communication system makes it possible to track the position of the monitoring target in a substantially continuous time series by communicating with the communication device held by the monitoring target and the smart meter.

When the band of the radio wave emitted by the communication device is the 920 MHz band, the attenuation of the radio wave due to the presence of the member is remarkable. Therefore, in this case, the increase in the first strength of the communication device is remarkable because the monitoring target holding the communication device opens the doorway. Therefore, in such a case, the communication device can more accurately determine whether or not the monitoring target has gone out of the building.

On the other hand, the third intensity before time Ta tends to decrease as the communication device 201 moves away from the second communication device 181. After that, between the time Ta and the time Te, it decreases significantly as the doorway 711 closes, and after the time Te, it falls below the threshold Th5. The third intensity after the time Te tends to decrease as the communication device 201 moves away from the second communication device 181.
