<First Embodiment>
First, the overall picture and the outline of the management system of the present embodiment will be described with reference to FIG. The management system includes a mobile terminal device 10, a relay device 20, and a processing system 30. The mobile terminal device 10 is possessed by a monitoring target (eg, an elderly person, a child, etc.) that is a target for monitoring the whereabouts. The relay device 20 of the present embodiment is a smart meter (electric energy meter), and is installed for each electric power consumer, for example, on the premises of each electric power consumer. That is, the relay devices 20 are scattered over a wide area and installed. The processing system 30 is a server (eg, a cloud server) and is managed by a business operator that provides a monitoring service.

The mobile terminal device 10 executes the first notification process and the second notification process. The power required for the second notification process is smaller than the power required for the first notification process.

In the first notification process, the mobile terminal device 10 calculates the position information of the own device based on the GPS signal, and transmits the calculated position information and the mobile terminal identification information of the own device to the processing system 30. The mobile terminal device 10 is connected to the Internet via a communication base station (eg, a wireless LAN (local area network) base station, a mobile phone base station, a smartphone base station, etc.), and is a processing system 30 using, for example, an IP (internet protocol). Communicate with.

In the second notification process, the mobile terminal device 10 transmits the mobile terminal identification information of its own device to at least one relay device 20 that is capable of communication among the plurality of relay devices 20. The mobile terminal device 10 communicates with the relay device 20 by a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-Fi HaLow, RPMA, Flexnet, etc., which belong to LPWA (low power wide area).

The mobile terminal device 10 executes either the first notification process or the second notification process at predetermined timing intervals. When the mobile terminal device 10 is in a state of being able to communicate with at least one of the plurality of relay devices 20 at a predetermined timing, the mobile terminal device 10 executes the second notification process.

The processing system 30 manages the position of the mobile terminal device 10 based on the information received from the mobile terminal device 10 in response to the first notification process and the information received from the relay device 20 in response to the second notification process. do.

By the way, when the second notification process is executed, that is, when the mobile terminal device 10 is in a state where it can communicate with any of the relay devices 20, the mobile terminal device 10 is near the relay device 20. Conceivable. The position of the mobile terminal device 10 can be estimated by specifying the relay device 20 in a state of being able to communicate with each mobile terminal device 10 based on the information received from the relay device 20 in response to the second notification process.

The management system of the present embodiment executes the second notification process having relatively low power consumption in an environment where the second notification process can be executed, and relatively consumes in an environment in which the second notification process cannot be executed. The first notification process with high power consumption is executed. That is, the second notification process is preferentially executed, and when the second notification process cannot be executed, the first notification process is executed. Therefore, it is possible to suppress the execution of the first notification process, which consumes a relatively large amount of power, that is, the use of GPS. As a result, power saving can be realized.

Example: Display, speaker, printer, mailer, etc.), including an interface for outputting information to an external device, external server, etc. The processor 1A can issue a command to each module and perform a calculation based on the calculation result thereof.

Next, the functional configuration of the mobile terminal device 10 will be described. FIG. 3 shows an example of a functional block diagram of the mobile terminal device 10. As shown in the figure, the mobile terminal device 10 has a first notification unit 11 and a second notification unit 12.

The first notification unit 11 calculates the position information based on the GPS signal, and executes the first notification process of transmitting the position information and the mobile terminal identification information of the own device to the processing system 30. The first notification unit 11 may associate the time information with the location information and the mobile terminal identification information and transmit the time information to the processing system 30. The time information may be the time at which the location information and the mobile terminal identification information are transmitted to the processing system 30, the time at which the location information is acquired, or any other time equivalent thereto. ..

The first notification unit 11 connects to the Internet via a communication base station (eg, wireless LAN base station, mobile phone base station, smartphone base station, etc.), and communicates with the processing system 30 by, for example, IP.

The second notification unit 12 executes a second notification process of transmitting the mobile terminal identification information of the own device to at least one relay device 20 that is communicable in the plurality of relay devices 20. The second notification unit 12 may associate the time information with the mobile terminal identification information and transmit it to the relay device 20. The time information may be the time at which the mobile terminal identification information is transmitted to the relay device 20, or may be another time equivalent thereto.

The second notification unit 12 communicates with the relay device 20 by a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-FiHaLow, RPMA, Flexnet, etc. belonging to LPWA, for example.

The power required for the second notification process is smaller than the power required for the first notification process.

The mobile terminal device 10 executes either the first notification process or the second notification process at predetermined timing intervals.

When a state in which communication is possible with at least one of the plurality of relay devices 20 at a predetermined timing, the second notification unit 12 executes the second notification process. Then, when the relay device 20 is not in a communicable state at a predetermined timing, the first notification unit 11 executes the first notification process. The means by which the mobile terminal device 10 determines whether or not there is a relay device 20 capable of communicating at each timing is not particularly limited. An example will be described below.

In the present embodiment, the predetermined timing is exemplified, but is not limited to, for example, every 5 minutes, every 10 minutes, every 15 minutes, every 30 minutes, every 1 hour, and the like.

Here, an example of the processing flow of the mobile terminal device 10 of the present embodiment will be described with reference to the flowchart of FIG.

The mobile terminal device 10 continues monitoring (S10) as to whether or not the predetermined timing has been reached, while the process is not completed (No in S50).

At a predetermined timing (Yes in S10), it is determined whether the mobile terminal device 10 is in a state of being able to communicate with at least one of the plurality of relay devices 20 (S20).

When it is in a state where it can communicate with at least one relay device 20 (Yes in S20), the mobile terminal device 10 executes the second notification process (S30). On the other hand, when communication is not possible with any of the relay devices 20 (No in S20), the mobile terminal device 10 executes the first notification process (S40). After that, the same process is repeated.

Next, the functional configuration of the relay device 20 will be described. FIG. 5 shows an example of a functional block diagram of the relay device 20. As shown in the figure, the relay device 20 has a first communication unit 21 and a second communication unit 22. The relay device 20 of this embodiment is a smart meter (electric energy meter). Although not shown, the relay device 20 can further include various functional units included in the smart meter.

The first communication unit 21 receives the mobile terminal identification information from the mobile terminal device 10. The first communication unit 21 communicates with the mobile terminal device 10 by a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-FiHaLow, RPMA, Flexnet, etc., which belong to LPWA.

The second communication unit 22 transmits the mobile terminal identification information received by the first communication unit 21 to the processing system 30 in association with the identification information of the own terminal. The second communication unit 22 may transmit the mobile terminal identification information, the identification information of the own terminal, and the time information in association with each other to the processing system 30.

When the time information is associated with the mobile terminal identification information received from the mobile terminal device 10 by the first communication unit 21, the second communication unit 22 associates the time information with the mobile terminal identification information. It may be transmitted to the processing system 30.

When the time information is not associated with the mobile terminal identification information received by the first communication unit 21 from the mobile terminal device 10, the second communication unit 22 associates the time information with the mobile terminal identification information. It may be transmitted to the processing system 30. That is, the relay device 20 (smart meter) may associate the time information with the mobile terminal identification information received from the mobile terminal device 10. The time information associated with this case may be the time when the mobile terminal identification information is received from the mobile terminal device 10, or may be another time equivalent thereto.

The second communication unit 22 is a communication method for smart meters, for example, a wireless multi-hop method for hop-commuting between smart meters, a portable method using 3G or LTE, a PLC method using a power line, and the like, and the processing system 30. connect.

Next, the timing at which the second communication unit 22 transmits the mobile terminal identification information received by the first communication unit 21 to the processing system 30 will be described.

First, the second communication unit 22 transmits information other than the information related to the monitoring service (such as the mobile terminal identification information received by the first communication unit 21) to the processing system 30. Specifically, the second communication unit 22 transmits power information to the processing system 30 at predetermined time intervals (eg, every 30 minutes, every 15 minutes, every hour, etc.). The electric power information is, for example, an integrated value [Wh] of electric power consumed by each electric power consumer within the latest predetermined time, but is not limited thereto.

Then, the second communication unit 22 of the present embodiment transmits the mobile terminal identification information received from the previous transmission to that time to the processing system 30 at the same timing as the transmission of the power information. That is, as shown in FIG. 6, the relay device 20 stores the mobile terminal identification information received by the first communication unit 21 in association with the time and the transmission flag. The time is a value of time information associated with the mobile terminal identification information. In the transmission flag, a value indicating whether or not each mobile terminal identification information has been transmitted to the processing system 30 is entered.

Then, based on the accumulated information, the second communication unit 22 collectively transmits the mobile terminal identification information received from the previous transmission to that time to the processing system 30 at the same timing as the transmission of the power information. The transmitted mobile terminal identification information may be deleted from the storage device. In this case, the transmission flag is unnecessary.

Next, the functional configuration of the processing system 30 will be described. The processing system 30 receives information received from the mobile terminal device 10 in response to the first notification process (hereinafter, may be referred to as "first information"), and from the relay device 20 in response to the second notification process. The position of the mobile terminal device 10 is managed based on the received information (hereinafter, may be referred to as "second information").

As shown in FIG. 7, the processing system 30 can collectively store the first information and the second information for each mobile terminal identification information. In FIG. 7, the time and the position are stored in association with each other.

The time is a value indicated by the time information included in the first information and the second information. The position is a position where it is estimated that the mobile terminal device 10 was present at each time. The position of each time is estimated based on the first information or the second information. As described above, the first information includes the position information calculated based on the GPS signal. Therefore, the position can be set to the position where the mobile terminal device 10 was present at that time.

On the other hand, the second information includes the identification information of the relay device 20, but does not include a value that directly indicates a specific position. Therefore, it is necessary to calculate the position where the mobile terminal device 10 exists from the second information. For example, as shown in FIG. 8, the processing system 30 may store the identification information of each of the plurality of relay devices 20 in association with the installation position. Then, the processing system 30 may calculate the position of the mobile terminal device 10 from the identification information of the relay device 20 by using the information.

When there is one relay device 20 that communicates with the mobile terminal device 10 at time t, that is, when there is one relay device 20 that transmits the second information associated with the time t to the processing system 30, the processing system 30 It is estimated that the portable terminal device 10 was present near the relay device 20 at time t. For example, it is presumed that the mobile terminal device 10 exists within a circle having a radius R (design matter) centered on the relay device 20.

On the other hand, when there are a plurality of relay devices 20 that communicate with the mobile terminal device 10 at time t, that is, when there are a plurality of relay devices 20 that transmit the second information associated with the time t to the processing system 30, the processing system. 30 estimates that the portable terminal device 10 was present near the plurality of relay devices 20 at time t. For example, it may be estimated that the mobile terminal device 10 is located at the center of an arbitrary area including a plurality of relay devices 20 at time t.

In addition, when there are a plurality of relay devices 20 communicating with the mobile terminal device 10 at time t, the processing system 30 of the relay device 20 having the strongest signal strength of communication with the mobile terminal device 10 at time t. It may be presumed that the mobile terminal device 10 was present nearby. For example, it may be presumed that the mobile terminal device 10 exists within a circle having a radius R (design matter) centered on the relay device 20.

In this case, when the relay device 20 receives the mobile terminal identification information from the mobile terminal device 10 by the second notification process, the signal strength of the communication between the mobile terminal device 10 and the first communication unit 21 at that time is received. May be measured. Then, when the second communication unit 22 transmits the mobile terminal identification information to the processing system 30, the associated signal strength may be further transmitted to the processing system 30. By executing these processes, it is possible to estimate the position of the relay device 20 based on the signal strength.

By the way, the processing system 30 can present the position of the managed mobile terminal device 10 to a predetermined user. The presentation of the information may be repeated at predetermined time intervals (design matters), or may be performed in response to a request from the user. For example, information may be presented by e-mail, a push notification function of an application, or the like, or information may be presented to a user who has logged in on a website.

The information presented to the user includes the latest estimated position of the mobile terminal device 10, the estimated position of the mobile terminal device 10 at the time specified by the user, the estimated movement locus of the mobile terminal device 10 in a predetermined time zone, and the like. By way of example, but not limited to these.

Next, a specific example of the management system of the present embodiment will be described with reference to FIG. It should be noted that the specific example is merely an example embodying the management system of the present embodiment, and the management system of the present embodiment is not limited to the specific example.

As shown in the figure, the mobile terminal device 10 is possessed by the monitoring target. In the steps (1) and (1)', the second notification unit 12 of the mobile terminal device 10 transmits a communication availability confirmation signal at predetermined timing intervals. The second notification unit 12 transmits a communication availability confirmation signal in a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-FiHaLow, RPMA, Flexnet, etc., which belong to LPWA.

When any of the relay devices 20 receives the communication possibility confirmation signal, the relay device (smart meter: SM) 20 that has received the communication possibility confirmation signal transmits the response signal as shown in (2). That is, the first communication unit 21 receives the communication availability confirmation signal transmitted from the mobile terminal device 10, and transmits a response signal in response to the reception.

After that, as shown in (3), the mobile terminal device 10 that has received the response signal transmits the mobile terminal identification information. As shown in (4), the relay device 20 that has received the mobile terminal identification information transmits the received mobile terminal identification information to the processing system (cloud) 30 in association with the identification information of the own terminal.

On the other hand, when neither of the relay devices 20 receives the communication availability confirmation signal, neither of the relay devices 20 transmits the response signal as shown in (2)'. The mobile terminal device 10 that fails to receive the response signal receives the GPS signal and calculates the position information as shown in (3)'. Then, as shown in (4)', the mobile terminal device 10 transmits the calculated position information to the processing system 30 via the communication base station.

That is, when a response to the communication availability confirmation signal is received from any of the relay devices 20, the second notification unit 12 executes the second notification process. Then, when the response to the communication availability confirmation signal is not received from any of the relay devices 20, the first notification unit 11 executes the first notification process.

The processing system 30 manages the position of the mobile terminal device 10 based on the information received from the mobile terminal device 10 as shown in (4)'and the information received from the relay device 20 as shown in (4). .. Then, as shown in (5), the observer is notified of the position of the monitoring target at an arbitrary timing.

Here, a modified example will be described. The smart meter (relay device 20) may acquire the mobile terminal identification information of the mobile terminal device 10 via the child meter.

That is, when the child meter receives a communication possibility confirmation signal transmitted by the mobile terminal device 10 in a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-Fi HaLow, RPMA, Flexnet, etc. belonging to LPWA, A response signal may be transmitted according to the same standard. Further, when the child meter receives the mobile terminal identification information transmitted by the mobile terminal device 10 according to the same standard, the child meter may transmit the information to the smart meter according to an arbitrary communication standard. At this time, the child meter may attach the identification information of the own device to the identification information of the mobile terminal. The communication standard between the child meter and the smart meter can adopt any existing technology. Then, the relay device 20 may attach the identification information of the child meter to the mobile terminal identification information received from the child meter and transmit it to the processing system 30.

The processing system 30 may estimate the position of the mobile terminal device 10 by using the installation position of the child meter registered in advance and the identification information of the child meter attached to the mobile terminal identification information. The position estimation method is the same as the process using the identification information of the relay device 20 attached to the mobile terminal identification information.

Next, the operation and effect of the management system of the present embodiment will be described.

The mobile terminal device 10 of the present embodiment executes the second notification process having relatively low power consumption in an environment where the second notification process can be executed, and is relative in an environment in which the second notification process cannot be executed. The first notification process, which consumes a large amount of power, is executed. That is, the second notification process is preferentially executed, and if the second notification process cannot be executed, the first notification process is executed. Therefore, it is possible to suppress the execution of the first notification process, which consumes a relatively large amount of power, that is, the use of GPS. As a result, the power saving of the mobile terminal device 10 can be realized.

By the way, in the techniques of Patent Documents 1 and 2, the processing contents are switched according to the environment to be monitored. However, the conditions for switching the processing contents are clearly different between the techniques of Patent Documents 1 and 2 and the present embodiment. Therefore, the realized effects are also clearly different.

The techniques of Patent Documents 1 and 2 are configured to use GPS when the monitored object is outdoors and perform other processing which does not use GPS when the monitored object is indoors. That is, the processing content is different depending on whether the monitoring target is outdoors or indoors.

On the other hand, in the present embodiment, GPS is used when communication with any relay device 20 is not possible, and other processing without using GPS is performed when communication with any relay device 20 is possible. .. That is, the processing contents are different depending on whether or not communication with any of the relay devices 20 is possible.

Therefore, in the case of the technologies of Patent Documents 1 and 2, GPS is always used when the monitoring target is outdoors, but in the case of the present embodiment, GPS is not always used even when the monitoring target is outdoors. do not have. Therefore, the techniques of Patent Documents 1 and 2 and the present embodiment are clearly different from each other in, for example, the speed of power consumption of the mobile terminal when the monitoring target is outdoors. Specifically, the present embodiment can suppress the speed of power consumption.

Further, in the management system of the present embodiment, a smart meter can be used as the relay device 20. Smart meters are widespread and are scattered over a wide area. By using such a smart meter as the relay device 20, it is possible to secure a wide area in which the mobile terminal device 10 can execute the second notification process. As a result, the power saving of the mobile terminal device 10 can be realized more effectively. Further, since the existing equipment can be used as the relay device 20, there is no need to provide new equipment. Therefore, the cost burden can be reduced.

Further, in the present embodiment, the relay device 20 can transmit the mobile terminal identification information received from the mobile terminal device 10 up to that time to the processing system 30 at the timing of transmitting the power information. By doing so, it is possible to avoid congestion in the communication network of the smart meter.

By the way, as described above, in order to avoid congestion of the communication network of the smart meter, when the relay device 20 collectively transmits the mobile terminal identification information acquired within a predetermined time to the processing system 30, where was it at each timing? The estimation accuracy becomes worse. In order to avoid the inconvenience, in the present embodiment, time information can be added to the mobile terminal identification information transmitted / received in the second notification process. By using the time information, the processing system 30 can accurately estimate where the mobile terminal device 10 was at each timing. That is, in order to collectively transmit the mobile terminal identification information and the time information received from the previous transmission to that time to the processing system 30 at the same timing as the transmission of the power information, the processing system 30 is attached to the mobile terminal identification information. Based on the time information, it is possible to estimate where the mobile terminal device was at each timing and the movement trajectory.

<Second embodiment>
In the management system of the present embodiment, if the predetermined timing (hereinafter, "notification timing") for executing the first notification process or the second notification process by the mobile terminal device 10 is different depending on the state of the mobile terminal device 10. Let me. Other configurations of the management system are the same as in the first embodiment. Hereinafter, the points different from the first embodiment will be described, and the description of the common points will be omitted.

"Pattern 1"
When the mobile terminal device 10 is in a state where it can communicate with the predetermined relay device 20 among the plurality of relay devices 20, it is notified as compared with the case where it is not in a state where it can communicate with the predetermined relay device 20. Increase the timing interval.

The predetermined relay device 20 is a relay device 20 installed in a place recognized as safe by the observer, for example, a home to be monitored, a relative's home to be monitored, a hospital to be visited, a nursing care facility to be visited, or the like. be. In the present embodiment, when the mobile terminal device 10 is near such a relay device 20, that is, when the monitoring target is in a safe place, the time interval of the notification timing is increased, and the first notification process and the second notification process are performed. Power saving is realized by reducing the number of executions of the notification process.

Here, a method of determining whether or not the mobile terminal device 10 is in a state of being able to communicate with a predetermined relay device 20 will be described.

"Method 1"
In method 1, the identification information of one or a plurality of relay devices 20 is registered in the mobile terminal device 10. The relay device 20 transmits the identification information of its own device to the mobile terminal device 10 in a communicable state.

The identification information of the mobile terminal device 10 and the received relay device 20 is collated with the identification information of the relay device 20 registered in advance. When the received identification information is registered in the own device, it is determined that the communication with the predetermined relay device 20 is possible. On the other hand, if the received identification information is not registered in the own device, it is determined that the communication with the predetermined relay device 20 is not possible.

"Method 2"
In the method 2, the mobile terminal identification information of one or a plurality of mobile terminal devices 10 is registered in the relay device 20.

When the relay device 20 receives the mobile terminal identification information due to the second notification process executed by the mobile terminal device 10, the relay device 20 collates with the mobile terminal identification information registered in advance. When the received mobile terminal identification information is registered in the own device, it is determined that the mobile terminal device 10 is in a state of being able to communicate with the predetermined mobile terminal device 10. Then, the first communication unit 21 transmits a signal (determination result) indicating that fact to the mobile terminal device 10.

On the other hand, if the received mobile terminal identification information is not registered in the own device, it is determined that the communication with the predetermined mobile terminal device 10 is not possible. Then, the first communication unit 21 transmits a signal (determination result) indicating that fact to the mobile terminal device 10.

The mobile terminal device 10 determines whether or not it is in a state of being able to communicate with the predetermined relay device 20 based on the received determination result.

"Pattern 2"
When the movement amount of the mobile terminal device 10 is smaller than the reference, the mobile terminal device 10 increases the time interval of the notification timing as compared with the case where the movement amount is larger than the reference.

When the amount of movement of the monitored object is small, for example, it is assumed that the person is resting on a park bench or talking with an acquaintance. If the amount of movement of the monitored object is small, the need for monitoring becomes small. Therefore, in such a case, power saving is realized by increasing the time interval of the notification timing and reducing the number of executions of the first notification process and the second notification process.

Here, an example of a method for determining whether the movement amount of the mobile terminal device 10 is larger or smaller than the reference will be described.

The latest notification timing that has been executed is P1, and the notification timing immediately before that is P0. When the notification process executed in P0 (first notification process or second notification process) and the notification process executed in P1 are different, that is, one of them is the first notification process and the other is the second notification process. In this case, the mobile terminal device 10 determines that the amount of movement is larger than the reference. Then, the time interval from P1 to the next notification timing P2 is set to a relatively small value.

On the other hand, when both the notification process executed by P0 and the notification process executed by P1 are the first notification processes, the mobile terminal device 10 performs each of the first notification process of P0 and the first notification process of P1. Based on the calculated position information, the distance between the position at P0 and the position at P1 is calculated. Then, when the calculated distance is larger than the reference value held in advance, the mobile terminal device 10 determines that the movement amount is larger than the reference value. Then, the time interval from P1 to the next notification timing P2 is set to a relatively small value. Further, when the calculated distance is smaller than the reference value held in advance, the mobile terminal device 10 determines that the movement amount is smaller than the reference value. Then, the time interval from P1 to the next notification timing P2 is set to a relatively large value.

Further, when the notification process executed by P0 and the notification process executed by P1 are both the second notification processes, the mobile terminal device 10 has each of the second notification process of P0 and the second notification process of P1. It is determined whether or not the communication relay devices 20 match. When there are a plurality of relay devices 20 that have communicated with each other, and the relay devices 20 that have communicated with each other are exactly the same, it may be determined that they match. When the communication relay device 20 does not match, the mobile terminal device 10 determines that the movement amount is larger than the reference. Then, the time interval from P1 to the next notification timing P2 is set to a relatively small value. Further, the mobile terminal device 10 determines that the movement amount is smaller than the reference when the communication relay devices 20 match. Then, the time interval from P1 to the next notification timing P2 is set to a relatively large value.

"Pattern 3"
The mobile terminal device 10 combines the pattern 1 and the pattern 2.

Next, a specific example of the management system of the present embodiment will be described with reference to FIG. It should be noted that the specific example is merely an example embodying the management system of the present embodiment, and the management system of the present embodiment is not limited to the specific example.

Here, an example in which the above-mentioned pattern 3 is adopted and the method 1 is adopted in the pattern 1 will be described. Then, "the time interval of the notification timing when it is in a state where it can communicate with the predetermined relay device 20 is T1", and "it is not in a state where it can communicate with the predetermined relay device 20 and the amount of movement is small." The time interval of the notification timing when it is smaller than the standard is T2, and the time interval of the notification timing when it is not in a state where it can communicate with the predetermined relay device 20 and the movement amount is larger than the standard is T3. It should be noted that T1> T2> T3.

As shown in the figure, the mobile terminal device 10 is possessed by the monitoring target. In the steps (1) and (1)', the second notification unit 12 of the mobile terminal device 10 transmits a communication availability confirmation signal at predetermined timing intervals. In this example, T1, T2, or T3 is set as the time interval for transmitting the communication availability confirmation signal. The second notification unit 12 repeatedly transmits a communication availability confirmation signal at a set time interval. The second notification unit 12 transmits a communication availability confirmation signal in a communication standard such as Wi-SUN, NB-IoT, LoRaWAN, SIGFOX, Wi-FiHaLow, RPMA, Flexnet, etc., which belong to LPWA.

When any of the relay devices 20 receives the communication possibility confirmation signal, the relay device (smart meter: SM) 20 that has received the communication possibility confirmation signal transmits the response signal as shown in (2). That is, the first communication unit 21 receives the communication availability confirmation signal transmitted from the mobile terminal device 10, and transmits a response signal in response to the reception.

After that, as shown in (3), the mobile terminal device 10 that has received the response signal transmits the mobile terminal identification information. As shown in (4), the relay device 20 that has received the mobile terminal identification information transmits the received mobile terminal identification information to the processing system (cloud) 30 in association with the identification information of the own terminal.

Further, the relay device 20 transmits the identification information of the own device to the mobile terminal device 10 at an arbitrary timing after receiving the communication possibility confirmation signal. For example, it may be transmitted together with a response signal.

The mobile terminal device 10 that has received the identification information of the relay device 20 collates the received identification information of the relay device 20 with the identification information of the relay device 20 registered in advance. When the received identification information is registered in the own device, it is determined that the mobile terminal device 10 is in a state of being able to communicate with the predetermined relay device 20. Then, the time interval for transmitting the communication availability confirmation signal is set to T1.

On the other hand, when the received identification information is not registered in the own device, it is determined that the mobile terminal device 10 is not in a state where it can communicate with the predetermined relay device 20. In this case, the mobile terminal device 10 determines whether or not the movement amount of the own device is larger than the reference. The details of the judgment are as described above. When the movement amount is smaller than the reference, the mobile terminal device 10 sets the time interval for transmitting the communication availability confirmation signal to T2. On the other hand, when the movement amount is larger than the reference, the mobile terminal device 10 sets the time interval for transmitting the communication availability confirmation signal to T3.

Further, when neither of the relay devices 20 receives the communication availability confirmation signal, neither of the relay devices 20 transmits the response signal as shown in (2)'. The mobile terminal device 10 that fails to receive the response signal receives the GPS signal and calculates the position information as shown in (3)'. Then, as shown in (4)', the mobile terminal device 10 transmits the calculated position information to the processing system 30 via the communication base station.

When the response signal is not received from any of the relay devices 20, the mobile terminal device 10 determines whether or not the movement amount of the own device is larger than the reference. The details of the judgment are as described above. When the movement amount is smaller than the reference, the mobile terminal device 10 sets the time interval for transmitting the communication availability confirmation signal to T2. On the other hand, when the movement amount is larger than the reference, the mobile terminal device 10 sets the time interval for transmitting the communication availability confirmation signal to T3.

The processing system 30 manages the position of the mobile terminal device 10 based on the information received from the mobile terminal device 10 as shown in (4)'and the information received from the relay device 20 as shown in (4). .. Then, as shown in (5), the observer is notified of the position of the monitoring target at an arbitrary timing.

According to the management system of the present embodiment described above, the same operation and effect as those of the first embodiment can be realized.

Further, when the monitoring target is in a predetermined place such as a place recognized as safe by the observer, the time interval of the notification timing is increased, and the number of times the first notification process and the second notification process are executed. Can be reduced. As a result, the power saving of the mobile terminal device 10 can be realized.

Further, for example, when the movement amount of the monitoring target is small, that is, when the necessity of monitoring is small, the time interval of the notification timing may be increased and the number of executions of the first notification process and the second notification process may be reduced. can. As a result, the power saving of the mobile terminal device 10 can be realized.

The relay device 20 of the present embodiment transmits the mobile terminal identification information received from the mobile terminal device 10 to the processing system 30 at other timings. Other configurations of the management system are the same as in the first and second embodiments. Hereinafter, the points different from the first and second embodiments will be described, and the description of the common points will be omitted.

The second communication unit 22 of the relay device 20 transmits the mobile terminal identification information received from the mobile terminal device 10 to the processing system 30 at a timing different from the timing of transmitting the power information. For example, when the first communication unit 21 receives the mobile terminal information from the mobile terminal device 10, the second communication unit 22 may transmit the mobile terminal information to the processing system 30 accordingly (real-time processing). In addition, the second communication unit 22 may transmit the mobile terminal identification information received from the mobile terminal device 10 to the processing system 30 at a time interval different from the time interval for transmitting the power information (batch processing).

In the case of the present embodiment, the processing system 30 may add time information (eg, reception time) to the mobile terminal identification information received from the relay device 20.

According to the management system of the present embodiment, the same operation and effect as those of the first and second embodiments can be realized.
