JP6740731B2 - Communication device, data collection method, program, and safety confirmation system - Google Patents

Description

The present invention relates to a communication device, a data collection method, a program, and a safety confirmation system.

As one of the paths for acquiring the measurement data measured by the smart meter, there is a communication path connecting the smart meter and an electronic device having a communication function (for example, a HEMS (Home Energy Management System) device). A communication device such as a home gateway device can acquire the measurement data of the smart meter via the above-described communication path by using a communication method such as Wi-SUN (Wireless Smart Utility Network) of 920 MHz band. In addition, in order for the electronic device having the above-mentioned communication function to communicate with the smart meter, an authentication process using the authentication information issued for each smart meter is required.

The following Patent Document 1 discloses a technique in which a distribution board can be communicated with a smart meter via a B route (a communication path connecting a smart meter and an electronic device having a communication function). In the technique of Patent Document 1, the distribution board includes a communication device. This communication device acquires authentication information for a smart meter from an input device (general-purpose PC (Personal Computer), tablet terminal, etc.) or an external server communicably connected to the input device, and acquires the acquired authentication information from the smart meter. The data is stored in the storage device provided in the distribution board. When the authentication information of the smart meter is acquired from the external server via the input device, the necessary authentication information is read from the external server using the information input to the input device. Specifically, the authentication information is associated with the user identification information (for example, address or name) in advance, and should be transmitted to the communication device of the distribution board by using the user identification information input to the input device. Authentication information is specified. As a result, the distribution board can communicate with the smart meter via the B route by using the authentication information set in the storage device.

In addition, further services using measurement data obtained from smart meters are also being considered. For example, Patent Document 2 below discloses a safety confirmation service that estimates the safety of the service contractor based on the fluctuation range of measurement data obtained from a smart meter installed in the service contractor's home.

It should be noted that the following Patent Documents 3 and 4 are documents that disclose acquiring the current position of the garbage collection vehicle and utilizing it for garbage collection work.

International Publication No. 2015/045345 JP, 2005-001878, A JP, 2008-015991, A JP, 2004-131225, A

In the safety confirmation service disclosed in Patent Document 2, it is required to collect all measurement data of the smart meter of the service user (contractor) on a regular basis. Here, when the measurement data of the smart meter is acquired through the communication path connecting the smart meter and the electronic device having the communication function, the service user acquires the HEMS device (such as a home gateway device compatible with HEMS). It is necessary to introduce the HEMS device and perform a preparatory work for setting the HEMS device in a state in which it can communicate with the smart meter. This work is troublesome because the procedure with the electric power company until the acquisition of the authentication information is complicated, and the setting of the HEMS device is not easy for a person who is unfamiliar with handling the electric device. ..

An object of the present invention is to provide a technique for solving the above-mentioned problems.

The communication device 10 establishes communication with the smart meter 30 and collects measurement data from the smart meter 30. The communicable range between the communication device 10 and the smart meter 30 changes as the mobile body 20 moves. In addition, it is preferable that the mobile body 20 regularly moves along a fixed route in that measurement data can be collected regularly. Although not particularly limited, examples of such a moving body 20 include a garbage truck. The moving body 20 is not limited to the garbage collection vehicle, but may be a vehicle or a drone provided for the purpose of collecting measurement data. The communication device 10 transmits the acquired measurement data of each smart meter 30 to the server device 40 on the cloud using a network such as 3G or LTE (Long Term Evolution). The server device 40 analyzes the measurement data of each smart meter 30 received from the communication device 10. In addition, the server device 40 contacts the user terminal 50 registered in advance as an emergency contact when the abnormality is suspected from the result of analysis of the measurement data. The user terminal 50 is, for example, a terminal used by a third party such as a family member or an acquaintance or a civilian member.

[Functional configuration]
Hereinafter, the functional configuration of each device included in the safety confirmation system 1000 will be described with reference to FIG. FIG. 2 is a block diagram conceptually showing the functional structure of each device constituting the safety confirmation system 1000 of the first embodiment.

As shown in FIG. 2, the communication device 10 includes a position-related information acquisition unit 110, a reading unit 120, a measurement data acquisition unit 130, and a measurement data transmission unit 140. The communication device 10 is an external or built-in device provided in the mobile body 20. In addition, the communication device 10 establishes communication with the smart meter 30 existing in the communicable range, and acquires measurement data of the smart meter 30 (for example, data on the usage amount of electricity, gas, water, etc.). To do.

The position-related information acquisition unit 110 acquires position-related information regarding the position of the moving body 20. The position-related information is, for example, information indicating the current position of the moving body 20 or route information indicating a route along which the moving body 20 should move (that is, information indicating the position where the moving body 20 passes). However, the position related information acquired by the position related information acquisition unit 110 is not limited to these examples.

The reading unit 120 reads authentication information in wireless communication with each smart meter 30 based on the position-related information acquired by the position-related information acquisition unit 110. Specific processing of the reading unit 120 will be described later.

The authentication information is a set of an ID set for each smart meter 30 and authentication data (password or the like), and is information for establishing wireless communication with the smart meter 30. The authentication information of each smart meter 30 includes position information of the smart meter 30 (for example, information indicating the installation position of the smart meter 30 such as latitude/longitude information, or a reference point or area (address of the smart meter 30). It is stored in the authentication information storage unit 420 of the server device 40 in a state of being associated with (information indicating at least a part). The authentication information storage unit 420 may be included in another server device (not shown).

Upon receiving the position-related information of the mobile unit 20 from the reading unit 120, the authentication information transmission unit 410 of the server device 40 acquires the authentication information corresponding to the position-related information from the authentication information storage unit 420. Then, the authentication information transmitting unit 410 transmits the acquired authentication information to the communication device 10. Accordingly, the reading unit 120 can read the authentication information from the authentication information storage unit 420.

The measurement data acquisition unit 130 performs wireless communication using the authentication information read by the reading unit 120, and acquires the measurement data of the smart meter 30 corresponding to the authentication information. The measurement data acquisition unit 130 performs wireless communication by, for example, a specific low power wireless system (for example, Wi-SUN) using the 920 MHz band. The specific low-power wireless system using the 920 MHz band has low power consumption, a long reach, and radio waves with other wireless as compared with a wireless LAN (Local Area Network) (so-called Wi-Fi (Wireless Fidelity)). It has the feature of being less likely to cause interference. Further, the specific low power wireless system using the 920 MHz band is excellent in radio wave wraparound characteristics, and thus stable communication can be realized even in a place where there is a wall or an obstacle. Further, the specific low power wireless system using the 920 MHz band is preferable in that the communication speed is faster (up to about 200 kbps) than other specific low power wireless systems (400 MHz band). Also, the measurement data acquisition unit 130 is not limited to this, and may perform wireless communication by another communication method such as ZigBee (registered trademark) that uses the 2.4 Ghz band.

When wireless communication is established between the communication device 10 and the smart meter 30, the transmission/reception unit 310 of the smart meter 30 reads the measurement data accumulated in the measurement data storage unit 320 and transmits it to the communication device 10. The transmission/reception unit 310 reads the measurement data for an arbitrarily determined period (for example, the past one hour, the past several hours, half a day, or one day) from the measurement data storage unit 320 and transmits it to the communication device 10. can do.

The measurement data transmission unit 140 transmits the measurement data of the smart meter 30 acquired by the measurement data acquisition unit 130 in association with the identification information of the smart meter 30. The measurement data transmission unit 140 transmits measurement data to an external device such as the server device 40, for example. When there is another external device (not shown) having a database for accumulating measurement data, the measurement data transmitting unit 140 may transmit the measurement data acquired from the smart meter 30 to the other external device. Further, the measurement data transmitting unit 140 can use, for example, the ID included in the authentication information used when acquiring the measurement data as the identification information of the smart meter 30. Further, for example, the measurement data transmitting unit 140 may use information unique to each smart meter 30 that is associated with the measurement data and transmitted from the smart meter 30, as the identification information of the smart meter 30.

In the server device 40, the measurement data analysis unit 430 analyzes the measurement data transmitted from the measurement data transmission unit 140 together with the identification information of the smart meter. The measurement data analysis unit 430 extracts a data pattern of measurement data for each smart meter identification information. Then, the abnormality notification unit 440 determines whether or not the data pattern obtained as a result of the analysis shows a predefined abnormal data pattern. The abnormal data pattern is not particularly limited, but for example, the amount of electricity, gas, or water used has not changed for a certain period of time, or the total amount of electricity, gas, or water has increased monotonically over a certain period of time. And so on. When such an abnormal data pattern is obtained as an analysis result, the abnormality notification unit 440 notifies the user terminal 50 registered as the predetermined contact information that there is a possibility that an abnormality has occurred. Send notification information. The telephone number, the mail address, and the like of the user terminal 50 used for transmitting the notification information are associated with the identification information of the smart meter in advance, and are connected to the server device 40 or another device communicably connected to the server device 40. It is stored in the storage device of the device.

The user terminal 50 receives the notification information from the abnormality notification unit 440 via the reception unit 510. Then, the display processing unit 520 outputs the notification information to the user of the user terminal 50 by using the display device or the voice output device of the user terminal 50.

[Operation example]
Hereinafter, an operation example of the safety confirmation system 1000 according to the first embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing the flow of processing of the communication device 10. Further, FIG. 4 is a flowchart showing the flow of processing of the server device 40.

First, a processing flow of the communication device 10 will be described with reference to FIG.

The position-related information acquisition unit 110 is the current position information of the mobile unit 20 obtained based on the position-related information of the mobile unit 20 (for example, GPS (Global Positioning System) information or the position information of a wireless base station), or the storage 104. Etc., the route information of the moving body 20 and the like recorded in advance are acquired (S102).

The reading unit 120 transmits the acquired position-related information to the server device 40 (S104). In the server device 40, the authentication information to be transmitted to the communication device 10 is specified from the authentication information stored in the authentication information storage unit 420 based on the position related information of the mobile body 20. Then, the reading unit 120 acquires the authentication information specified by the server device 40 (S106).

The measurement data acquisition unit 130 uses the authentication information acquired by the read unit 120 to transmit a communication establishment request from each smart meter 30 located in a wireless communicable range (S108). The measurement data acquisition unit 130 broadcasts, for example, a communication establishment request including the authentication information acquired by the reading unit 120 within the communicable range. Then, the smart meter 30 that has received the correct authentication information returns the measurement data via the wireless communication path. When a plurality of pieces of authentication information are acquired in S106, the measurement data acquisition unit 130 broadcasts each piece of authentication information included in the communication establishment request. Then, the measurement data acquisition unit 130 acquires the measurement data transmitted from each smart meter 30 (S110). Then, the measurement data transmitting unit 140 transmits the measurement data collected from each smart meter 30 to the server device 40 or another external device having a database for accumulating the measurement data (S112). Here, the measurement data transmission unit 140 transmits the identification information for identifying each smart meter and the measurement data in association with each other.

Next, a processing flow of the server device 40 will be described with reference to FIG.

The measurement data analysis unit 430 analyzes the measurement data transmitted from the communication device 10 and extracts a data pattern for each smart meter 30 identified by the identification information (S202).

The abnormality notification unit 440 compares the data pattern extracted by the measurement data analysis unit 430 with a predefined data pattern for abnormality detection, and determines whether the extracted data pattern is a pattern indicating an abnormality. Yes (S204).

If the extracted data pattern is not an abnormal data pattern (S204: NO), the process described below is not executed.

On the other hand, when the extracted data pattern is an abnormal data pattern (S204: YES), the abnormality notification unit 440 outputs the identification information of the smart meter 30 associated with the measurement data that is the basis of the data pattern. The destination information of the user terminal 50 registered as the predetermined contact is acquired by using (S206). For example, the abnormality notification unit 440 uses information as shown in FIG. FIG. 5 is a diagram showing an example of information in which identification information of the smart meter 30 and destination information for communicating with a predetermined user terminal 50 are associated with each other. In the example of FIG. 5, the identification information (meter ID) of the smart meter 30 and the destination information such as the telephone number and the mail address of the user terminal 50 are associated with each other. The abnormality notification unit 440 is possessed by a third party (for example, a family member, an acquaintance, or a civilian member) related to the owner of the smart meter 30 based on the identification information of the smart meter 30 based on the information as shown in FIG. The destination information of the user terminal 50 that operates can be acquired.

Then, the abnormality notification unit 440 uses the acquired destination information of the user terminal 50 to notify the owner of the smart meter 30 in which the measured data shows an abnormal movement that some kind of accident has occurred. It is transmitted (S208). The owner of the user terminal 50 can notice the occurrence of the abnormal situation by confirming the notification information.

[Operation example]
Hereinafter, a specific operation example of the safety confirmation system 1000 according to the second embodiment will be described. In addition, below, the case where the collection work of the measurement data of the smart meter 30 is entrusted to the garbage collector under the jurisdiction of the local government is illustrated. In this case, the moving body 20 is a garbage truck that regularly moves along a predetermined route. Since the garbage truck regularly travels around a route that covers the area in which it is in charge, by using it as the mobile unit 20 equipped with the communication device 10, the measurement data used for safety confirmation can be collected regularly and without fail. You can expect the effect of doing.

<First operation example>
In this operation example, the reading unit 120 uses the current position information of the mobile unit 20 as the position-related information of the mobile unit 20. The position-related information acquisition unit 110 can acquire the current position information of the mobile unit 20 at predetermined intervals by using, for example, the GPS information obtained from the GPS measuring device 1051 and the position information of the wireless base station. Then, the reading unit 120 transmits the current position information of the mobile unit 20 acquired by the position-related information acquisition unit 110 to the server device 40. Upon receiving the current position information of the moving body 20 from the reading unit 120, the authentication information transmission unit 410 of the server device 40 associates the current position information with the position information satisfying a predetermined condition. From the authentication information storage unit 420. Then, the authentication information transmitting unit 410 transmits the acquired authentication information to the communication device 10. As a result, the reading unit 120 can read the authentication information in which the position information satisfying a predetermined condition is associated with the current position information of the moving body 20, from the authentication information storage unit 420.

A specific operation will be described with reference to FIG. FIG. 8 is a sequence diagram showing a first operation example of the safety confirmation system 1000 according to the second embodiment.

The position-related information acquisition unit 110 of the communication device 10 sequentially acquires, for example, the current position information (latitude/longitude information) of the garbage collection vehicle generated at predetermined intervals by the GPS measuring device 1051. Not limited to this, the position-related information acquisition unit 110 of the communication device 10 may acquire the current position information of the garbage collection vehicle depending on the timing at which the garbage collection vehicle stops, for example. In this case, the position-related information acquisition unit 110 is generated, for example, immediately before or after the timing at which the stop of the garbage collection vehicle is detected from the current position information generated by the GPS measuring device 1051 at predetermined intervals. Get current location information. Further, the position-related information acquisition unit 110 transmits a start instruction to the GPS measuring instrument 1051 when detecting that the garbage collecting vehicle has stopped, and collects the dust collecting object generated by the GPS measuring instrument 1051 according to the instruction. The current position information of the vehicle may be acquired. The position-related information acquisition unit 110 can detect that the garbage collection vehicle has stopped by using speed information that can be acquired from a CAN (Control Area Network) of the garbage collection vehicle. Specifically, the position-related information acquisition unit 110 determines that the speed information acquired from the CAN or the like is equal to or lower than a predetermined threshold speed (for example, 5 km/h) for a predetermined threshold time (for example, 5 to 10 seconds). By determining whether or not it has continued, it is possible to determine whether or not the garbage truck is stopped. Then, the reading unit 120 of the communication device 10 transmits the position information of the garbage collection vehicle acquired by the position-related information acquisition unit 110 to the server device 40 via the second communication interface 107 (S302).

The authentication information transmitting unit 410 of the server device 40 uses the received current position information of the garbage collection vehicle and the position information associated with each authentication information item to output the authentication information item to be transmitted to the communication device 10. It is specified from the authentication information stored in the authentication information storage unit 420 (S304).

For example, the authentication information storage unit 420 stores the authentication information of the smart meter 30 and the position information (latitude/longitude information) of the reference point such as the garbage collection site closest to the installation location of the smart meter 30 in association with each other. Suppose that In this case, the authentication information transmission unit 410 uses the current position information of the garbage collection vehicle and the position information of the reference point associated with the authentication information of the smart meter 30 to determine the garbage collection vehicle and the reference point. The distance between the two is calculated, and it is determined whether the distance is less than or equal to a predetermined threshold. The distance calculated here may be a straight-line distance on the map or a moving distance along the road. Then, the authentication information transmitting unit 410 uses the authentication information associated with the reference point whose distance to the garbage collection vehicle is determined to be equal to or less than the predetermined threshold as the authentication information to be transmitted to the communication device 10. Identify.

Further, for example, the authentication information storage unit 420 may store the area information including position information (latitude/longitude information) of three or more points and the authentication information in association with each other, instead of the reference point. In this case, the authentication information transmitting unit 410 may specify the authentication information to be transmitted to the communication device 10, based on the positional relationship between the current position information of the garbage collection vehicle and the range defined by the area information. it can. Specifically, the authentication information transmitting unit 410 transmits, to the communication device 10, the authentication information associated with the area information defining the area including the position indicated by the current position information of the garbage truck. It is specified as authentication information that should be authenticated.

Further, for example, it is assumed that the authentication information storage unit 420 stores the authentication information of the smart meter 30 and the address information of the installation location of the smart meter 30 in association with each other. In this case, the authentication information transmission unit 410 informs the communication device 10 based on the address information obtained by converting the current position information (latitude/longitude information) of the garbage collection vehicle using a predetermined conversion function or the like. The authentication information to be transmitted can be specified. Specifically, the authentication information transmission unit 410 is associated with the address information indicating the same area as the address information obtained from the current position information of the garbage collection vehicle (for example, the address information having the same streets). The authentication information is specified as the authentication information to be transmitted to the communication device 10.

However, the examples given here are merely examples, and the present embodiment is not limited to these examples.

The authentication information transmission unit 410 of the server device 40 acquires the authentication information associated with the position information satisfying such a predetermined criterion from the authentication information storage unit 420 and transmits it to the communication device 10 (S306). ). In this example, it is assumed that the authentication information of the smart meter 30A and the authentication information of the smart meter 30B are acquired.

When the reading unit 120 of the communication device 10 acquires the authentication information transmitted from the server device 40 via the second communication interface 107 using 3G or LTE, the reading unit 120 stores the authentication information in the temporary storage area 150 (the memory 103 or the like). ) Is temporarily stored (S308).

If the reading unit 120 of the communication device 10 succeeds in reading the authentication information based on the current position information, the reading unit 120 may temporarily stop the transmission of the current position information of the garbage collection vehicle (S310). As an example, the position-related information acquisition unit 110 transmits a stop instruction to the GPS measuring device 1051 in response to the reading of the authentication information by the reading unit 120, and temporarily stops the operation of the GPS measuring device 1051. Not limited to this, the reading unit 120 may send a stop instruction to the GPS measuring device 1051. Further, the reading unit 120 of the communication device 10 may control whether or not to temporarily stop the transmission of the current position information of the garbage collection vehicle depending on whether the garbage collection vehicle is moving or stopped. In this case, when the reading unit 120 of the communication device 10 detects that the garbage truck is moving, it temporarily stops the transmission of the current position information of the garbage truck. For example, the reading unit 120 of the communication device 10 determines whether the speed information acquired from the CAN or the like exceeds a predetermined threshold speed (for example, 5 km/h) for a predetermined threshold time (for example, 5 to 10 seconds). By determining whether or not the garbage truck is moving, it can be determined. As a result, the power consumption of the communication device 10 can be reduced. In this case, the transmission of the current position information of the GP waste collection vehicle is restarted by satisfying a predetermined operation restart condition (described later).

The measurement data acquisition unit 130 of the communication device 10 reads the authentication information (authentication information of the smart meter 30A and the smart meter 30B) temporarily stored in the temporary storage area 150 (memory 103 or the like) (S312). Then, the measurement data acquisition unit 130 of the communication device 10 measures each of the smart meter 30A and the smart meter 30B via the first communication interface 106 that uses a specific low-power wireless system (Wi-SUN or the like) in the 920 MHz band, for example. Request data transmission (S314A, S314B). Then, the measurement data acquisition unit 130 establishes communication with the smart meter 30A using the authentication information of the smart meter 30A, and acquires the measurement data from the smart meter 30A (S316A). Further, the measurement data acquisition unit 130 establishes communication with the smart meter 30B using the authentication information of the smart meter 30B and acquires the measurement data from the smart meter 30B (S316B).

Here, since the authentication information becomes unnecessary after the measurement data can be acquired from each smart meter 30, the deletion unit 160 of the communication device 10 temporarily stores the unnecessary authentication information in the temporary storage area 150 (memory 103). Etc.). As a result, it is possible to reduce the risk of leakage of authentication information (information related to privacy) for enabling communication with the smart meter 30 installed in a private house. In FIG. 8, at the timing when the measurement data can be acquired from each smart meter 30, a process of deleting the authentication information used to acquire the measurement data from the temporary storage area 150 (memory 103 or the like) is executed. Examples are shown (S318A, S318B). However, the timing of deleting the authentication information is not limited to the example of FIG.

For example, the deleting unit 160 is used to acquire the measurement data when the data reception confirmation signal is received from the external device after transmitting the measurement data of the smart meter 30 to the external device (such as the server device 40). The authentication information may be deleted from the temporary storage area 150 (memory 103 or the like). By doing so, it is possible to reduce the risk of leakage of the authentication information and manage whether or not the server device 40 has been able to reliably acquire the measurement data of the smart meter 30. For example, if the reception confirmation signal from the server device 40 cannot be received within a predetermined time even though the measurement data is transmitted to the server device 40, the communication device 10 determines that the measurement data is normal to the server device 40. You can judge that it has not reached. In this case, the measurement data acquisition unit 130 retransmits the measurement data.

Further, for example, the deletion unit 160 determines whether or not a predetermined deletion condition based on the current position information of the garbage truck (moving body 20) is satisfied, and when the deletion condition is satisfied, the temporary storage area 150 (memory The authentication information stored in (eg, 103) may be deleted.

For example, when the authentication information is associated with the position information of the reference point (for example, the nearest garbage collection site), the deleting unit 160 determines the positional relationship between the current position of the garbage collection vehicle and the reference point. It is possible to determine whether to delete the authentication information stored in the temporary storage area 150. In this case, the reading unit 120 acquires the position information of the reference point associated with the authentication information together with the authentication information in S306. Then, the deletion unit 160 determines whether or not a deletion condition such as "the distance calculated using the current position information of the garbage truck and the acquired position information of the reference point exceeds a predetermined threshold value" is satisfied. If the deletion condition is satisfied, the authentication information stored in the temporary storage area 150 is deleted.

Further, for example, when the authentication information is associated with the area information (address or the like), the deletion unit 160 determines the temporary storage area 150 based on the correspondence between the current position of the garbage collection vehicle and the position indicated by the area information. It is possible to determine whether or not to delete the authentication information stored in. In this case, the reading unit 120 acquires the area information (address information) associated with the authentication information together with the authentication information in S306. Then, the deletion unit 160 determines whether a deletion condition such as “the address corresponding to the current position information of the garbage truck is different from the address indicated by the acquired area information” is satisfied, and when the deletion condition is satisfied. Then, the authentication information stored in the temporary storage area 150 is deleted.

Further, for example, when the authentication information is associated with area information (information defining an area formed by position information of three or more points), the deleting unit 160 defines the current position of the garbage truck and the area information. Whether to delete the authentication information stored in the temporary storage area 150 can be determined based on the positional relationship with the range. In this case, the reading unit 120 acquires the area information together with the authentication information in S306. Then, the deletion unit 160 determines whether a deletion condition such as “the position indicated by the current position information of the garbage collection vehicle is outside the range of the acquired area information” is satisfied, and when the deletion condition is satisfied, The authentication information stored in the temporary storage area 150 may be deleted.

Further, for example, when the authentication information is associated with the address information of the installation location of the smart meter 30, the deleting unit 160 stores the temporary storage area 150 in the temporary storage area 150 based on the address information obtained from the current position information of the garbage truck. It is possible to determine whether to delete the stored authentication information. Specifically, the deletion unit 160 determines whether or not a deletion condition such as “address information obtained from the current position information of the garbage collection vehicle changes in a portion higher than the chome” is satisfied, and the deletion condition is satisfied. In this case, the authentication information stored in the temporary storage area 150 may be deleted.

Further, the deletion unit 160 may delete the authentication information stored in the temporary storage area 150 according to the deletion instruction from the server device 40. Specifically, when transmitting the authentication information in S306, the server device 40 transmits an instruction to delete the authentication information stored in the temporary storage area 150 at that time. In this case, after the deleting unit 160 deletes the authentication information stored in the temporary storage area 150 according to the deletion instruction from the server device 40, the reading unit 120 temporarily stores the newly acquired authentication information in the temporary storage area 150. To remember.

Further, not limited to the above, the temporary storage area 150 may be configured by a volatile memory so that the authentication information of the smart meter 30 stored in the temporary storage area 150 is deleted when the power supply is cut off. Good. With this, it is possible to prevent the authentication information from being leaked when the communication device 10 is lost or the communication device 10 is stolen.

Then, the measurement data transmission unit 140 of the communication device 10 transmits the measurement data acquired by the measurement data acquisition unit 130 to the server device 40 via the second communication interface 107. The measurement data transmitting unit 140 of the communication device 10 transmits the measurement data in a state in which the identification information of each smart meter 30 is associated with each other so that the server device 40 can identify which smart meter 30 the measurement data is. .. The measurement data transmitting unit 140 uses, for example, information (ID or the like) unique to each smart meter 30 that is associated with the measurement data and transmitted from each smart meter 30, as identification information of the smart meter 30. Specifically, the measurement data transmission unit 140 of the communication device 10 transmits the measurement data of the smart meter 30A in association with the identification information (ID _A ) of the smart meter 30A (S320A). Further, the measurement data transmitting unit 140 of the communication device 10 transmits the measurement data of the smart meter 30B in association with the identification information (ID _B ) of the smart meter 30B (S320B). Note that the measurement data transmission unit 140 is not limited to the example of FIG. 8 and may collectively transmit the measurement information of each smart meter 30.

In addition, when the operation of the GPS measuring device 1051 is temporarily stopped in S310, the reading unit 120 of the communication device 10 determines whether a predetermined operation restart condition is satisfied. If the operation restart condition is satisfied, the reading unit 120 restarts the process of transmitting the current position information of the garbage truck to the server device 40 (S322). As an example, when the reading unit 120 determines that the operation restart condition is satisfied, the reading unit 120 instructs the position related information acquisition unit 110 to restart the operation of the GPS measuring instrument 1051. The position-related information acquisition unit 110 transmits an activation instruction to the GPS measuring instrument 1051 in response to this instruction and restarts the operation of the GPS measuring instrument 1051. Not limited to this, the reading unit 120 may send a start instruction to the GPS measuring instrument 1051. Note that the "predetermined operation restart condition" is, for example, "when the distance between the current position of the garbage truck and the reference point exceeds a predetermined threshold" or "address information obtained from the current position information of the garbage truck. If it fluctuates in a higher part". Further, the reading unit 120 of the communication device 10 may control whether or not to restart the transmission of the current position information of the garbage truck depending on whether the garbage truck is moving or stopped. In this case, when the reading unit 120 of the communication device 10 detects that the garbage truck is stopped, it restarts the transmission of the current position information of the garbage truck. For example, the reading unit 120 of the communication device 10 determines whether the speed information acquired from the CAN or the like continues for a predetermined threshold time (for example, 5 to 10 seconds) for a predetermined threshold speed (for example, 5 km/h) or less. By determining whether or not it is possible to determine whether or not the garbage truck is stopped.

The data analysis process in the server device 40 is as described in the first embodiment.

<Second operation example>
In this operation example, the reading unit 120 uses route information indicating a route along which the garbage collection vehicle should move, as position-related information of the moving body 20 (dust collection vehicle). Specifically, route information indicating a dust collection route assigned to each garbage collection vehicle is stored in advance in the memory 103 or the storage 104, and the position-related information acquisition unit 110 stores the route information from these storage units. Acquire as related information. Then, the reading unit 120 transmits the route information of the garbage collection vehicle acquired by the position-related information acquisition unit 110 to the server device 40. Upon receiving the route information of the garbage collection vehicle from the reading unit 120, the authentication information transmitting unit 410 of the server device 40 authenticates the authentication information in which position information satisfying a predetermined condition is associated with the route information. It is acquired from the business information storage unit 420. For example, when the route information of the garbage truck indicates a route that goes around "CC town, BB town, AA city", the authentication information transmitting unit 410 of the server device 40 includes position information that includes "CC town, BB town, AA city". The authentication information associated with is collectively obtained. Then, the authentication information transmitting unit 410 transmits the acquired authentication information to the communication device 10. As a result, the reading unit 120 can read from the authentication information storage unit 420 the authentication information in which the position information satisfying a predetermined condition is associated with the route information of the garbage collection vehicle.

A specific operation will be described with reference to FIG. FIG. 9 is a sequence diagram showing a second operation example of the safety confirmation system 1000 according to the second embodiment.

The position-related information acquisition unit 110 of the communication device 10 reads the route information of the garbage truck stored in the memory 103 or the storage 104 in advance, and the read unit 120 of the communication device 10 reads the route information from the second communication interface. It is transmitted to the server device 40 via 107 (S402).

The authentication information transmission unit 410 of the server device 40 uses the received route information of the garbage collection vehicle to send the authentication information to be transmitted to the communication device 10 to the authentication information stored in the authentication information storage unit 420. It is specified from the inside (S404).

This will be described more specifically with reference to FIG. FIG. 10 is a diagram for explaining the flow of acquiring authentication information in the second operation example of the second embodiment. In the example of FIG. 10, it is assumed that information indicating a route (arrow in the figure) that goes around 1 to 3 chomes of BB town in AA city is preset as route information of the garbage collection vehicle.

The reading unit 120 of the communication device 10 transmits the route information of the garbage collection vehicle to the server device 40 before the garbage collection work starts. The authentication information transmission unit 410 of the server device 40 searches the authentication information storage unit 420 for the authentication information to be transmitted to the communication device 10 using the acquired route information. In this example, the authentication information transmission unit 410 of the server device 40 authenticates the authentication information associated with the position information including the address “1-3 chome, BB-cho, AA city” obtained from the route information. A search is made from the business information storage unit 420. Then, the authentication information transmitting unit 410 of the server device 40 specifies the authentication information hit in the search as the authentication information to be transmitted to the communication device 10.

The authentication information transmission unit 410 of the server device 40 acquires the specified authentication information from the authentication information storage unit 420 and transmits it to the communication device 10 (S406). In this example, it is assumed that the authentication information of the smart meter 30A and the authentication information of the smart meter 30B are acquired.

When the reading unit 120 of the communication device 10 acquires the authentication information transmitted from the server device 40 via the second communication interface 107 using 3G or LTE, the reading unit 120 stores the authentication information in the temporary storage area 150 (memory 103). (S408).

The measurement data acquisition unit 130 of the communication device 10 reads the authentication information (authentication information of the smart meter 30A and the smart meter 30B) temporarily stored in the temporary storage area 150 (memory 103 or the like) (S412). Here, the measurement data acquisition unit 130 of the communication device 10 uses the current position information of the GPS measuring device 1051 to perform authentication information read from the temporary storage area 150 (that is, authentication used for wireless communication as described below). Information) may be narrowed down. Specifically, first, the measurement data acquisition unit 130 of the communication device 10 associates the current position information of the garbage collection vehicle obtained by the GPS measuring device 1051 with the authentication information stored in the temporary storage area 150. It is determined whether or not the distance between the two positions indicated by the two pieces of position information is within a predetermined threshold value by comparing the position information with the given position information. Then, the measurement data acquisition unit 130 of the communication device 10 selects the authentication information used for wireless communication from the authentication information stored in the temporary storage area 150 based on whether or not this distance is within a predetermined threshold value. Narrow down. By doing so, it is possible to suppress useless operations such as the communication device 10 reading the authentication information to be used near the end point of the route from the temporary storage area 150 at the start point of the route and broadcasting it. .. Then, the measurement data acquisition unit 130 of the communication device 10 measures each of the smart meter 30A and the smart meter 30B via the first communication interface 106 that uses a specific low-power wireless system (Wi-SUN or the like) in the 920 MHz band, for example. Request transmission of data (S414A, S414B). Then, the measurement data acquisition unit 130 establishes communication with the smart meter 30A using the authentication information of the smart meter 30A, and acquires the measurement data from the smart meter 30A (S416A). Further, the measurement data acquisition unit 130 establishes communication with the smart meter 30B by using the authentication information of the smart meter 30B and acquires the measurement data from the smart meter 30B (S416B).

Here, since the authentication information becomes unnecessary after the measurement data can be acquired from each smart meter 30, the deletion unit 160 of the communication device 10 stores the unnecessary authentication information in the temporary storage area 150 (memory 103). Etc.). As a result, it is possible to reduce the risk of leakage of authentication information (information related to privacy) for enabling communication with the smart meter 30 installed in a private house. In FIG. 9, when the measurement data can be acquired from each smart meter 30, a process of deleting the authentication information used to acquire the measurement data from the temporary storage area 150 (memory 103 or the like) is executed. Examples are shown (S418A, S418B). However, the timing of deleting the authentication information is not limited to the example of FIG.

For example, the deleting unit 160 is used to acquire the measurement data when the data reception confirmation signal is received from the external device after transmitting the measurement data of the smart meter 30 to the external device (such as the server device 40). The authentication information may be deleted from the temporary storage area 150 (memory 103 or the like). By doing so, it is possible to reduce the risk of leakage of the authentication information and manage whether or not the server device 40 has been able to reliably acquire the measurement data of the smart meter 30. For example, if the reception confirmation signal from the server device 40 cannot be received within a predetermined time even though the measurement data is transmitted to the server device 40, the communication device 10 determines that the measurement data is normal to the server device 40. You can judge that it has not reached. In this case, the measurement data acquisition unit 130 retransmits the measurement data.

Further, for example, the deletion unit 160 determines whether or not a predetermined deletion condition based on the current position information of the garbage truck (moving body 20) is satisfied, and when the deletion condition is satisfied, the temporary storage area 150 (memory The authentication information stored in (eg, 103) may be deleted.

For example, the deletion unit 160 compares the current position information of the garbage truck obtained from the GPS measuring device 1051 with the route information to determine whether or not the garbage truck has reached the end point position of the route indicated by the route information. To judge. When the deletion unit 160 determines that the garbage truck has reached the end point position of the route, the deletion unit 160 deletes the authentication information stored in the temporary storage area 150 (memory 103 or the like).

Further, for example, when the authentication information is associated with the area information (address or the like), the deletion unit 160 determines the temporary storage area 150 based on the correspondence between the current position of the garbage collection vehicle and the position indicated by the area information. It is also possible to determine the authentication information to be deleted from the authentication information stored in. In this case, the reading unit 120 acquires the area information (address information) associated with the authentication information together with the authentication information in S406. Further, the measurement data acquisition unit 130 may delete the authentication information already used during the wireless communication in S416A or S416B or the authentication information corresponding to the smart meter 30 from which the measurement data is normally acquired. Flag information indicating that is added. Then, the deletion unit 160 has authentication information that satisfies the deletion condition, such as "the address corresponding to the current position information of the garbage truck is different from the address indicated by the acquired area information and flag information is added". Is present and the authentication information satisfying the deletion condition is deleted from the temporary storage area 150.

Further, not limited to the above, the temporary storage area 150 may be configured by a volatile memory so that the authentication information of the smart meter 30 stored in the temporary storage area 150 is deleted when the power supply is cut off. Good. With this, it is possible to prevent the authentication information from being leaked when the communication device 10 is lost or the communication device 10 is stolen.

Then, the measurement data transmission unit 140 of the communication device 10 transmits the measurement data acquired by the measurement data acquisition unit 130 to the server device 40 via the second communication interface 107. The measurement data transmitting unit 140 of the communication device 10 transmits the measurement data in a state in which the identification information of each smart meter 30 is associated with each other so that the server device 40 can identify which smart meter 30 the measurement data is. .. The measurement data transmitting unit 140 uses, for example, information (ID or the like) unique to each smart meter 30 that is associated with the measurement data and transmitted from each smart meter 30, as identification information of the smart meter 30. Specifically, the measurement data transmission unit 140 of the communication device 10 transmits the measurement data of the smart meter 30A in association with the identification information (ID _A ) of the smart meter 30A (S420A). Further, the measurement data transmitting unit 140 of the communication device 10 transmits the measurement data of the smart meter 30B in association with the identification information (ID _B ) of the smart meter 30B (S420B). Note that the measurement data transmission unit 140 is not limited to the example of FIG. 9 and may collectively transmit the measurement information of each smart meter 30.

The data analysis process in the server device 40 is as described in the first embodiment.

[Action/effect]
As described above, according to the present embodiment, it is possible to obtain the same actions and effects as those of the first embodiment.

Further, in the present embodiment, the authentication information for establishing communication with the smart meter 30 is temporarily stored in the temporary storage area 150 and deleted after the measurement data is acquired from the smart meter 30. As a result, the time during which the communication device 10 holds the authentication information of the smart meter 30 of the service user is limited, and the security of the risk of leakage of the authentication information can be improved.

Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than the above may be adopted.

Further, in the plurality of flowcharts and sequence diagrams used in the above description, a plurality of steps (processes) are described in order, but the execution order of the steps executed in each embodiment is limited to the order described.
