[0012] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0013] 1, the gas meter management system 1 includes a gas meter 2, a wireless device 3, an alarm device 4, a cloud server 5 as an information processing system, an AI speaker 6, and multiple mobile terminals 7 such as smartphones. The AI ​​speaker 6 and the mobile terminals 7 are examples of "communication terminals."

[0014] The gas meter 2 is installed outside a detached house or an apartment building and measures the flow rate of gas supplied to the gas appliances in the dwelling unit. The gas meter 2 is also equipped with a shutoff valve that shuts off the gas supply to the gas appliances in the dwelling unit in the event of a gas leak or other such event. The shutoff valve opens and closes in response to a user's voice command using the AI ​​speaker 6 or a user's operation command using the mobile terminal 7.

[0015] The wireless device 3 is installed outside a detached house or an apartment building close to the gas meter 2 and is connected to the gas meter 2 by wire so as to be able to communicate with it. Examples of a communication method between the gas meter 2 and the wireless device 3 include N-line and U-bus. Here, the communication between the gas meter 2 and the wireless device 3 may be an automatic selection method between the N-line and U-bus. Alternatively, the gas meter 2 and the wireless device 3 may be connected to be able to communicate wirelessly.

[0016] The wireless device 3 is connected to the cloud server 5 via a closed network so as to be able to communicate with it. Examples of communication methods between the wireless device 3 and the cloud server 5 include 1:N communication methods such as LTE (Long Term Evolution) and LPWA (Low Power Wide Area), and wireless multi-hop methods. The wireless device 3 transmits to the cloud server 5 various information such as the gas flow rate output from the gas meter 2 and alarm information output from the alarm device 4. The wireless device 3 also transmits to the gas meter 2 an instruction message output from the cloud server 5 instructing the gas meter 2 to open a valve. Note that instead of or in addition to the wireless device 3, a communication device that performs power line communication may be provided.

[0017] The alarm device 4 is installed inside a detached house or apartment building, and is wirelessly connected to the wireless device 3 and gas meter 2 so that they can communicate with each other. An example of a communication method between the alarm device 4 and wireless device 3 is U-bus air. The alarm device 4, wireless device 3, and gas meter 2 may also be connected to each other via wires so that they can communicate with each other.

[0018] If the alarm device 4 detects a gas leak within the home, it will sound an alarm (issue an alert). Furthermore, if the alarm device 4 detects a gas leak, it will send an alarm message to the wireless device 3 and the gas meter 2. If the wireless device 3 receives an alarm message from the alarm device 4, it will send a message indicating that the alarm device 4 has been activated to the cloud server 5. Furthermore, if the gas meter 2 receives an alarm message from the alarm device 4, it will shut off the gas supply using the shut-off valve.

[0019] The cloud server 5 is composed of a computer that operates according to a program. In addition to the function of automatically collecting various information and meter reading information required for centralized monitoring of the gas meter 2, the cloud server 5 stores a program for realizing the function of linking the AI ​​speaker 6 and mobile terminal 7 with the gas meter 2 and the alarm device 4. In other words, the cloud server 5 provides, as a cloud service, an IOT platform for realizing centralized monitoring of the gas meter 2, automatic meter reading, and linking the AI ​​speaker 6, gas meter 2, and alarm device 4. Examples of this cloud service include Paas (Platform as a Service) such as AWS Lambda (registered trademark) or Faas (Function as a service).

[0020] The AI ​​speaker 6 is a speaker that can use an AI assistant that supports interactive voice operation, and is also called a smart speaker. The AI ​​speaker 6 is installed and used in the home. Examples of the mobile terminal 7 include a smartphone and a tablet. The mobile terminal 7 is a communication terminal that the user can carry and use.

[0021] The AI ​​speaker 6 and the mobile terminal 7 are connected wirelessly or wired to be able to communicate with the cloud server 5. Examples of connections between the AI ​​speaker 6, the mobile terminal 7 and the cloud server 5 include connections via wireless communication such as Wi-Fi or Bluetooth (registered trademark) and an Internet line, connections via a mobile Wi-Fi router, and connections via a mobile phone communication network using an AI home gateway.

[0022] The AI ​​speaker 6 and mobile terminal 7 of this embodiment are linked to the gas meter 2 and alarm device 4 via the cloud server 5, and output notifications, for example, when the alarm device 4 sounds, when the gas meter 2 is shut off again, or when gas supply transitions from a prohibited state to an permitted state. The AI ​​speaker 6 and mobile terminal 7 also send user instructions to the cloud server 5, for example, when the alarm device 4 sounds, when gas supply transitions from a prohibited state to an permitted state, etc. The cloud server 5 identifies the wireless device 3 linked to the AI ​​speaker 6 and mobile terminal 7 and sends a command message to the wireless device 3 to open the valve. The wireless device 3 sends the command message to open the valve to the corresponding gas meter 2, and the gas meter 2 executes the valve open operation.

[0023] Fig. 2 is a block diagram showing an outline of the cloud server 5 in Fig. 1. The cloud server 5 includes a notification guideline server 51, a centralized monitoring server 52, an automatic meter reading server 53, an IOT platform 54, and a database (hereinafter abbreviated as "DB") 55 as a storage unit.

[0024] The notification guideline server 51 is a server that notifies information and receives instructions using the AI ​​speaker 6 and the mobile terminal 7. The centralized monitoring server 52 is a server that executes monitoring processing to monitor the gas meter 2. The automatic meter reading server 53 executes meter reading processing to collect meter reading values ​​of the gas meter 2. The IOT platform 54 links these servers 51 to 53.

[0025] The DB 55 stores the ID of the radio 3, and the IDs of the AI ​​speaker 6 and the mobile terminal 7 linked to the ID of the radio 3. An example of the ID of the AI ​​speaker 6 is a number issued by the AI ​​speaker 6. An example of the ID of the mobile terminal 7 is an account ID of an SNS (Social Networking Service).

[0026] Next, the operation of the gas meter management system 1 configured as described above will be described with reference to Figures 3 to 6. When a gas shutoff event occurs, such as the detection of a gas leak by the alarm device 4, the gas meter 2 closes the shutoff valve, shutting off the gas (S1 in Figure 3). At the same time, the gas meter 2 and the wireless device 3 are linked via N-line or U-bus communication (S2). At this time, the wireless device 3 transmits a message by wireless communication to the IOT platform 54 indicating the reason for the gas shutoff and that the shutoff valve is in a closed state (S3).

[0027] The IOT platform 54 transmits the message to two locations: the centralized monitoring server 52, which functions as a first receiving unit, and the notification guideline server 51 (S4). At this time, the IOT platform 54 reads from the DB 55 the IDs of all AI speakers 6 and mobile terminals 7 linked to the ID of the radio 3 that transmitted the message. The IOT platform 54 assigns the read IDs of the AI ​​speakers 6 and mobile terminals 7 to the message and transmits it to the notification guideline server 51. The notification guideline server 51 transmits a shutdown notification according to the reason for the gas shutdown to the AI ​​speakers 6 and mobile terminals 7 whose IDs are assigned to the message (S5). The AI ​​speaker 6 outputs the shutdown notification by voice (S6). The mobile terminal 7 displays the shutdown notification on its screen (S7).

[0028] Next, when the AI ​​speaker 6 receives a voice command to restore gas, such as "make gas available" (S8 in FIG. 4), it transmits the input voice to the notification guideline server 51, for example, via Wi-Fi communication (S9). The notification guideline server 51 converts the voice command into a message instructing the restoration of gas and transmits it to the centralized monitoring server 52, which functions as a second receiving unit (S10). At this time, the notification guideline server 51 assigns the ID of the AI ​​speaker 6 to the message instructing the restoration of gas and transmits it to the centralized monitoring server 52.

[0029] Next, the centralized monitoring server 52 functions as a first transmission unit, reads out the ID of the wireless device 3 linked to the ID of the AI ​​speaker 6 from the DB 55, and transmits a message to the gas meter 2 via the wireless device 3 with the read ID to instruct the gas meter 2 to restore gas (to shift the shutoff valve from a closed state to an open state) (S11). Upon receiving the message, the gas meter 2 executes a valve opening operation using the shutoff valve (S12).

[0030] At the same time, the gas meter 2 and the wireless device 3 are linked via N-line or U-bus communication (S13). At this time, the wireless device 3 performs the valve opening operation and then transmits a message indicating the restoration status to the IOT platform (S14). The restoration status includes a restoration completion notification indicating that the gas supply has been restored, and a restoration obstruction notification indicating that restoration was not possible due to a restoration obstruction factor.

[0031] The IOT platform 54 transmits a message indicating the recovery status to two places: the centralized monitoring server 52 and the notification guideline server 51 (S15 in FIG. 5). At this time, the IOT platform 54 reads from the DB 55 the IDs of all AI speakers 6 and mobile terminals 7 linked to the ID of the radio 3 that transmitted the message. The IOT platform 54 functions as a second transmission unit and assigns the read IDs of the AI ​​speakers 6 and mobile terminals 7 to a message and transmits the message to the notification guideline server 51. The notification guideline server 51 functions as a second transmission unit and transmits a recovery status notification to the AI ​​speakers 6 and mobile terminals 7 whose IDs are assigned to the message (S16). The AI ​​speaker 6 outputs the recovery status notification by voice (S17). The mobile terminal 7 displays the recovery status notification on its screen (S18).

[0032] On the other hand, a case will be described where a user of the mobile terminal 7 who has received the cutoff notification performs a restoration operation using the mobile terminal 7. When the mobile terminal 7 inputs a restoration operation (S19 in FIG. 6), the mobile terminal 7 transmits the restoration operation input to the notification guideline server 51 (S20). The notification guideline server 51 transmits a message instructing gas restoration to the centralized monitoring server 52 (S21). After that, the same operations as S11 to S18 shown in FIGS. 3 and 4 are performed, and therefore detailed explanations will be omitted here.

[0033] Through the above operations, as shown in Figure 7, when a restoration instruction is given using the AI ​​speaker 6, the cloud server 5 restores the gas meter 2, and upon receiving the restoration status, transmits the restoration status to a mobile terminal 7 different from the AI ​​speaker 6 and displays the restoration status. As a result, for example, even if a family member in the home performs a restoration operation using the AI ​​speaker 6, the restoration status can be notified to family members who are away from the AI ​​speaker 6 in the home or who are outside the home via the mobile terminal 7.

[0034] 8, when a restoration instruction is given using the mobile terminal 7, the cloud server 5 restores the gas meter 2, and upon receiving the restoration status, transmits the restoration status to an AI speaker 6 different from the mobile terminal 7 and displays the restoration status. As a result, even if a family member outside the home or even inside the home but far from the AI ​​speaker 6 performs a restoration operation using the mobile terminal 7, the restoration status can be notified to the family member inside the home via the AI ​​speaker 6.

[0035] Next, the linking of the ID of the wireless device 3 and the mobile terminal 7 will be described. The user operates the mobile terminal 7 to launch an SNS application and register the official account of the gas meter management system 1 as a friend. After that, the user operates the mobile terminal 7 to open the official account screen and tap the "Link with gas meter" button. By tapping, the camera function of the mobile terminal 7 is activated, and the QR code (registered trademark) attached to the wireless device 3 can be read.

[0036] When the user operates the mobile terminal 7 to read the QR code (registered trademark) and taps the send button, the radio ID indicated in the QR code (registered trademark) and the user's SNS account ID are sent to the cloud server 5 and stored in DB55.

[0037] Next, we will explain how the ID of the radio 3 is linked to the AI ​​speaker 6. When the AI ​​speaker 6 receives a voice input such as "Tell me your ID," it outputs the ID by voice, such as "I will issue you a four-digit number. The number is ____." The user operates the mobile device 7 to open the official account screen and taps the "Link with AI speaker" button. This displays the ID input screen for the AI ​​speaker 6, and when the user enters the ID and taps the send button, the ID of the AI ​​speaker 6 and the user's SNS account ID are sent to the cloud server 5. The cloud server 5 links the ID of the AI ​​speaker 6 to the radio ID linked to the SNS account ID and stores it in DB 55.

[0038] According to the embodiment described above, the cloud server 5 transmits the restoration status of the gas meter 2 to the mobile terminal 7, which is a communication terminal different from the AI ​​speaker 6 that received the restoration instruction. The cloud server 5 also transmits the restoration status of the gas meter 2 to the AI ​​speaker 6, which is a communication terminal different from the mobile terminal 7 that received the restoration instruction. This makes it possible to notify the restoration status to a person other than the person who issued the restoration instruction.

[0039] According to the above-described embodiment, the cloud server 5 transmits the recovery status of the gas meter 2 to all communication terminals (AI speakers 6, mobile terminals 7) linked to the radio 3 of that gas meter 2. This makes it possible to notify the users of all communication terminals linked to the radio 3 of the recovery status.

[0040] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0041] According to the embodiment described above, the cloud server 5 transmits the recovery status to all communication terminals (AI speaker 6, mobile terminal 7) linked to the radio 3, but this is not limited to this. For example, the type of communication terminal (AI speaker 6 or mobile terminal 7) may be stored in the DB 55. Then, when the cloud server 5 receives a recovery instruction from the mobile terminal 7, it may transmit the recovery status only to the AI ​​speaker 6. Furthermore, when the cloud server 5 receives a recovery instruction from the AI ​​speaker 6, it may transmit the recovery status only to the mobile terminal 7. Furthermore, when the cloud server 5 receives a recovery instruction from the mobile terminal 7, it may transmit the recovery status to another mobile terminal 7. The user may use the mobile terminal 7 to set which communication terminal the recovery status is to be transmitted to.
