The second communication unit 76 is a communication device capable of wireless communication by a communication method (second wireless communication method) according to the known Bluetooth (registered trademark) wireless communication standard. The second communication unit 76 wirelessly communicates with the communication unit 11 of the gas stove 1 using the second wireless communication method. Specifically, the control circuit 71 and the second communication unit 76 cooperate to transmit and receive information to and from the gas stove 1 . The second communication unit 76 receives an instruction to the gas stove 1 (for example, a burner extinguishing instruction) from the information terminal 80 .

The control circuit 10 of the gas stove 1 and the control circuit 71 of the relay terminal 70 control the communication unit 11 and the second communication unit 76 so that the gas stove 1 performs wireless communication with the relay terminal 70 according to the second wireless communication method. First control is performed. The first control is started in response to the establishment of the first communication start condition. This is performed after pairing is established between the main unit 1A and the relay terminal 70. FIG. More specifically, when both the gas stove 1 and the relay terminal 70 are in the power-on state and the distance between the gas stove 1 and the relay terminal 70 is such that Bluetooth (registered trademark) communication can be performed between the gas stove 1 and the relay terminal 70 Pairing is performed by a known pairing method (for example, a pairing method in which the identification information (ID) sent from the relay terminal 70 to the gas stove 1 is authenticated by the gas stove 1) in accordance with the Bluetooth (registered trademark) standard between them, The first control described above is performed while the pairing state is maintained. For example, when the identification information (ID) of the relay terminal 70 is sent from the relay terminal 70 to the stove body 1A, the control circuit 10 of the stove body 1A registers (stores) the identification information (ID) in the registration unit 13. If it is registered, communication with the relay terminal 70 is permitted to enter a pairing state, and wireless communication is performed with the relay terminal 70 by the second wireless communication method.

The control circuit 10 of the gas stove 1 and the control circuit 71 of the relay terminal 70 communicate with the information terminal 80 via the relay terminal 70 while the gas stove 1 performs wireless communication with the relay terminal 70 according to the second wireless communication method. Second control is performed to control the communication unit 11, the first communication unit 75, and the second communication unit 76 so as to perform wireless communication. During this second control, the control circuit 10 of the gas stove 1 and the control circuit 71 of the relay terminal 70 wirelessly transmit information of the gas stove 1 to the information terminal 80 and wirelessly transmit information of the information terminal 80 to the gas stove 1. perform the second control in cooperation with each other. The second control is control based on the first control described above, and is started, for example, when the second communication start condition is satisfied. Specifically, when communication by the second wireless communication method is established between the stove main body 1A and the relay terminal 70 (more specifically, when the stove main body 1A and the relay terminal 70 When a predetermined condition is satisfied (for example, a predetermined operation is performed on the operation unit 12 or the operation unit 73 of the gas stove 1, a predetermined operation is performed on the information terminal 80, or other communication (when the start condition is satisfied), or may be started according to other conditions.

Next, the server 90 will be explained.
Server 90 is configured to be accessible to wide area network 91 . The first communication unit 75 can wirelessly communicate with the communication unit 84 of the information terminal 80 via the server 90 . The server 90 is configured, for example, as a known computer, and includes at least a control circuit, a communication section, and a storage section (not shown). The control circuit can control the communication unit, the storage unit, and the like. The communication unit is an interface for data communication with the wide area network 91 . The storage unit stores programs and the like for executing communication processing with the outside.

Next, the information terminal 80 will be explained.
The information terminal 80 communicates with the server 90 via a communication network. As shown in FIG. 5, the information terminal 80 includes a control circuit (second control section) 81, a display section (second display section) 82, an operation section 83, and a communication section (second terminal side communication section) 84. , provided. The information terminal 80 is configured as a portable information processing terminal such as a smart phone or a tablet terminal, and can operate using a secondary battery (not shown) as a power supply. Although FIGS. 1 and 5 illustrate the information terminal 80 configured as a smart phone, the configuration may be other than the smart phone as long as it is a portable terminal having an information processing function.

The control circuit 81 is configured as, for example, a known information processing device such as a microcomputer, and includes a known arithmetic device such as a CPU and other peripheral circuits, and can perform various controls and calculations. The display unit 82 is, for example, a display unit that forms a part of a known touch panel display device, and is configured as a known image display device such as a liquid crystal display or an organic electroluminescence display. The operation unit 83 is configured, for example, as a known touch panel arranged so as to cover the front of the display unit 82, and is configured to cover the display unit 82 with a transparent configuration that allows the image of the display unit 82 to be visually recognized from the outside. . Note that the example shown here is merely an example, and the display unit 82 may have any configuration as long as it can display an image in a state that the user can visually recognize it. The operation unit 83 may be configured to allow information to be input by a user's operation, and may include an input interface (such as a button) other than a touch panel.

The communication unit 84 is a communication device capable of performing wireless communication by a communication method (second wireless communication method) according to a known wireless communication standard such as WiFi (registered trademark), LTE, 4G, etc. other than Bluetooth (registered trademark). . The communication unit 84 can wirelessly communicate with the first communication unit 75 of the relay terminal 70 via the server 90 .

The notification unit 85 is composed of the control circuit 81 and the display unit 82 . The notification unit 85 notifies the outside by displaying on the display unit 82 . For example, when the information terminal 80 receives third intermediate information (for example, information including information indicating completion of fire extinguishing) transmitted from the server 90, the notification unit 85 responds to the reception of the third intermediate information. Notification (for example, notification of completion of fire extinguishing) is performed. Further, the notification unit 85 notifies the abnormality when the information terminal 80 does not receive the third intermediate information within a predetermined time (first time described later) after the operation information is transmitted from the information terminal 80 to the server 90. I do. Further, when the information terminal 80 receives the fourth intermediate information described later, at least one of the first terminal and the stove main body is abnormal (for example, the communication between the gas stove 1 and the relay terminal 70 is in an abnormal state). Notify the specified abnormality.

Next, communication control by the cooking system 100 will be described.
In cooking system 100 , gas stove 1 performs wireless communication with information terminal 80 via relay terminal 70 . An application program (cooking app) related to control of the cooking system 100 is installed in the relay terminal 70 and the information terminal 80, and the gas stove 1 is connected to the information terminal via the relay terminal 70 while the app is activated in each terminal. communicate with 80; The application program installed in the information terminal 80 is a program capable of executing control as shown in FIG. The application program installed in relay terminal 70 is a program capable of executing control as shown in FIG. Further, the gas stove 1 stores a program capable of executing control as shown in FIG.

FIG. 6 illustrates the flow of control performed in the cooking system 100. As shown in FIG. FIG. 6 illustrates a case where the user performs a fire extinguishing operation (an operation to instruct extinguishing of the gas stove 1) using the information terminal 80. In FIG. In this example, the user operates the operation unit 83 of the information terminal 80 to input information instructing to extinguish all the gas burners of the gas stove 1 (each of the stove units 4A, 4B, 4C and the grill 3) (extinguishing operation). It is carried out.

The information terminal 80 (second terminal) transmits operation information corresponding to the predetermined operation to the server in response to a predetermined operation performed on the operation unit 83 . For example, when the above fire extinguishing operation (input of information instructing fire extinguishing) is performed, the information terminal 80 transmits a command (fire extinguishing operation command) corresponding to the fire extinguishing operation to the server 90 as operation information. This extinguishing operation command is a command for extinguishing all gas burners, and is information including a command specifying such a command.

After transmitting the operation information, the information terminal 80 causes the display unit 82 to display according to the transmission of the operation information. For example, in the example of FIG. 6, the information terminal 80, after starting transmission of the fire extinguishing operation command described above, displays on the display unit 82 as a dialog display that the fire extinguishing operation command is being transmitted.

When receiving the operation information transmitted from information terminal 80 (second terminal), server 90 transmits first intermediate information corresponding to the operation information to relay terminal 70 (first terminal). The first intermediate information is information that can specify the contents of the operation information transmitted from the information terminal 80, and can be information including a command (for example, a fire extinguishing operation command) included in the operation information, for example. For example, in the example of FIG. 6, when the server 90 receives the above fire extinguishing operation command, the server 90 transmits a fire extinguishing request notification (a notification corresponding to the fire extinguishing operation command) as an example of the first intermediate information to the relay terminal 70. Then, the relay terminal 70 is made to perform a push notification corresponding to the operation information (for example, a push notification indicating that a fire extinguishing request has been made). This fire extinguishing request notification corresponds to an example of the first intermediate information, and is information for notifying the fire extinguishing operation command (instructing to extinguish all gas burners). This is information to be notified to the relay terminal 70 .

When receiving the first intermediate information transmitted from the server 90, the relay terminal 70 (first terminal) transmits instruction information corresponding to the first intermediate information to the stove body 1A. The instruction information is information that can specify the content of the first intermediate information, and for example, information that includes a command (for example, a fire extinguishing operation command) included in the operation information that triggered the transmission of the first intermediate information. can be done. In the example of FIG. 6, when the relay terminal 70 receives the above-described fire extinguishing request notification (first intermediate information) from the server 90, the relay terminal 70 performs a push notification to the gas stove 1 (specifically, the stove main body 1A). A fire extinguishing request command is transmitted as an example of instruction information. The fire extinguishing request command is a command corresponding to a fire extinguishing request notification from the server 90 (that is, a command corresponding to a fire extinguishing operation command from the information terminal 80), and commands (all command) to the gas stove 1 to extinguish the gas burner.

When a command is received from the relay terminal 70, the gas stove 1 (specifically, the stove main body 1A) performs an operation according to the received command. When receiving the instruction information, it performs a corresponding operation corresponding to the instruction information and transmits response information to the relay terminal 70 . The response information is information that can specify that the instruction information has been received by the stove main body 1A, and is information that can specify, for example, that the above-described corresponding operation has been started.

In the example of FIG. 6, when the stove main body 1A receives a fire extinguishing request command (a command for instructing fire extinguishing of all gas burners) as an example of instruction information, the fire extinguishing request is performed as a response operation corresponding to the received fire extinguishing request command. It performs an operation (specifically, an operation to extinguish all gas burners (fire extinguishing operation)) instructed by the command included in the command. Then, when the stove main body 1A starts a corresponding action (fire extinguishing operation) corresponding to the fire extinguishing request command in response to the reception of the fire extinguishing request command, the stove main body 1A sends the relay terminal 70 a response command as an example of the response information (for example, received A command to the effect that the corresponding operation corresponding to the received command is being executed). In the example of FIG. 6, when the stove main body 1A receives the fire extinguishing request command from the relay terminal 70 and starts the response operation (the operation of extinguishing all the gas burners) in response to the fire extinguishing request command, the fire extinguishing request command In addition to performing a corresponding action (action to extinguish all gas burners) according to the situation, a command indicating that this corresponding action is being executed (fire extinguishing command) is sent to the relay terminal 70 as an example of response information. ing.

When receiving the response information transmitted from the stove body 1A, the relay terminal 70 (first terminal) transmits second intermediate information corresponding to the response information to the server. The second intermediate information is information that can specify the contents of the response information. This second intermediate information is also information that can specify that the instruction information has been received by the stove main body 1A, and is information that can specify, for example, that the above-described corresponding operation has been started. Specifically, when the relay terminal 70 receives the fire extinguishing command as the response command, the relay terminal 70 notifies the server 90 of the second intermediate information (specifically, the command corresponding to the fire extinguishing command). (stove operation result notification)).

When server 90 receives the second intermediate information transmitted from relay terminal 70 (first terminal), server 90 transmits third intermediate information corresponding to the second intermediate information to information terminal 80 (second terminal). In the example of FIG. 6 , when the server 90 receives the above-described fire extinguishing notification (stove operation result notification) as the second intermediate information from the relay terminal 70 , the server 90 receives the extinguishing notification (stove operation result notification) to the information terminal 80 . Information (third intermediate information) corresponding to the operation result notification) is transmitted to perform a push notification to the effect that it is being executed. For example, when the server 90 receives a fire extinguishing notification (stove operation result notification) from the relay terminal 70, information corresponding to the stove operation result notification (fire extinguishing notification) is sent to the information terminal 80 as the third intermediate information. to cause the information terminal 80 to give a push notification that the fire is being extinguished (fire extinguishing operation is in progress).

When the information terminal 80 (second terminal) receives the third intermediate information transmitted from the server 90, the notification unit 85 performs notification corresponding to the reception of the third intermediate information. In the example of FIG. 6, the information terminal 80 performs a push notification in response to receiving a fire extinguishing in-progress notification corresponding to an example of the third intermediate information from the server 90 after displaying the above-described dialog. , a screen displaying the state of the gas stove 1 (specifically, a screen corresponding to "information corresponding to the notification of extinguishing in progress") is displayed. For example, when the information terminal 80 receives a fire extinguishing notification from the server 90 (information corresponding to the fire extinguishing notification from the relay terminal 70) after displaying the above-described dialog, the information terminal 80 responds to the reception of the fire extinguishing notification. to display a screen for displaying the state of the gas stove 1 on the display unit 82 (for example, a screen of "fire extinguishing operation in progress" corresponding to the fire extinguishing notification as shown in FIG. 6). In the example of FIG. 6, the screen displaying the state of the gas stove 1 displays an image representing the image of the gas stove 1 and symbols and characters representing the states corresponding to the respective stove sections 4A, 4B, 4C and the grill 3. FIG. In FIG. 6, when each of the stove sections 4A, 4B, 4C and the grill 3 is extinguishing, "?" is displayed corresponding to each of the stove sections 4A, 4B, 4C and the grill 3. The "?" mark indicates that the part marked with "?" (the stove section or the grill) is in the process of extinguishing the fire. If the information terminal 80 does not receive a fire extinguishing completion command (to be described later) even after a predetermined time (for example, 10 seconds) has passed since the above fire extinguishing operation command was transmitted, the information terminal 80 displays a message to that effect (for example, timeout ) is displayed on the display unit 82 . The above-mentioned indication that the predetermined time has passed (for example, the indication that the time has expired) is obtained by adding an additional indication (for example, an additional indication such as a balloon) to the “extinguishing operation in progress” screen shown in FIG. It may be displayed, or the screen may be temporarily switched to display the time-out.

When a command is received from the relay terminal 70, the gas stove 1 performs an operation according to the received command, and when the operation is completed, transmits a command corresponding to the completion of the operation to the relay terminal 70. - 特許庁For example, after transmitting the fire extinguishing command described above, the gas stove 1 sends a fire extinguishing completion command ( response information).

When the relay terminal 70 receives a command corresponding to operation completion from the gas stove 1 , the relay terminal 70 transmits information to the effect that the operation is completed (operation result notification) to the server 90 . For example, when the relay terminal 70 receives a fire extinguishing completion command from the gas stove 1, the relay terminal 70 transmits to the server 90 information indicating completion of fire extinguishing (stove operation result notification, second intermediate information).

When the server 90 receives the information indicating that the operation is completed (notification of operation result) from the relay terminal 70, the server 90 transmits the information indicating that the operation is completed to the information terminal 80 to perform push notification. For example, when the server 90 receives the information indicating that the fire extinguishing has been completed from the relay terminal 70, the server 90 transmits the information indicating that the fire extinguishing is completed (third intermediate information) to the information terminal 80 to perform push notification. .

When the information terminal 80 receives the information indicating that the operation is completed from the server 90, the screen display (display of the state of the gas stove 1) on the display unit 82 is changed to the screen display corresponding to the information indicating that the operation is completed. Update. For example, when the information terminal 80 receives the information indicating that the fire extinguishing is completed from the server 90, the screen display (display of the state of the gas stove 1) on the display unit 82 is changed according to the information indicating that the extinguishing is completed. Update the screen display. In this case, for example, as shown in FIG. 6, the display unit 82 displays a message corresponding to each of the stove sections 4A, 4B, 4C and the grill 3 when each of the stove sections 4A, 4B and 4C and the grill 3 has been extinguished. "Delete" is displayed.

Next, the control of the cooking system 100 when communication is abnormal will be described.
If a communication error occurs during transmission of information from the information terminal 80 to the server 90 (for example, during transmission of a command corresponding to a fire extinguishing operation (fire extinguishing operation command)), communication between the information terminal 80 and the server 90 is cut off. or the server 90 is not operating normally. Therefore, when the information terminal 80 cannot transmit information (for example, a fire extinguishing operation command) to the server 90, the information terminal 80 displays on the display unit 82 that communication between the information terminal 80 and the server 90 is abnormal. to do For example, the information terminal 80 causes the display unit 82 to display "communication error" or "please check the radio wave condition of the information terminal 80".

If a communication error occurs when information is sent from the server 90 to the relay terminal 70 (for example, when sending a fire extinguishing request notification corresponding to a fire extinguishing operation command), the power of the relay terminal 70 may be off, or the WiFi (registered trademark) may be disabled. ) It is assumed that the communication in the communication method, etc. is disconnected. Therefore, when the server 90 cannot transmit information (for example, a fire extinguishing request notification) to the relay terminal 70, the first abnormality information (specifically, the relay (information indicating that the communication between the terminal 70 and the server 90 is abnormal), and display that the communication between the server 90 and the relay terminal 70 is abnormal. When the information terminal 80 receives the first abnormality information from the server 90, the information terminal 80 notifies the abnormality corresponding to the first abnormality information. For example, the information terminal 80 notifies an abnormal position corresponding to the first abnormal information (specifically, for example, a notification that the relay terminal 70 is in an abnormal position) as an abnormality notification corresponding to the first abnormal information. conduct. Furthermore, the information terminal 80 notifies of a coping method corresponding to the first abnormality information. As a notification of a coping method corresponding to the first abnormality information, for example, "Please display the status of the gas stove 1 on the display unit 82 and check whether it is in the extinguishing state, and if it is not in the extinguishing state, perform the extinguishing operation again. If the fire is still not extinguished, check the following: Is the relay terminal 70 in a state of wireless communication with another device (for example, a WiFi router) using the WiFi (registered trademark) communication method, etc.? Is the power on? Is the cooking application running on the relay terminal 70?” (hereinafter referred to as confirmation display).

If a communication error occurs when transmitting information from the relay terminal 70 to the gas stove 1 (for example, when sending a fire extinguishing request command corresponding to a fire extinguishing operation command), the power of the gas stove 1 may be off or the Bluetooth (registered trademark) may be connected. It is assumed that the communication by the communication method or the like is disconnected. Therefore, when the relay terminal 70 cannot transmit information (for example, a fire extinguishing request command) to the gas stove 1, the relay terminal 70 transmits the second abnormality information to the information terminal 80 to the effect that the communication is abnormal. The information terminal 80 is caused to display (push notification) that the communication with the relay terminal 70 is abnormal. Specifically, the relay terminal 70 transmits the second abnormality information to the server 90 , and the server 90 receiving the second abnormality information transmits the second abnormality information (specifically, information indicating that the communication between the relay terminal 70 and the gas stove 1 is abnormal). When the information terminal 80 receives the second abnormality information from the server 90, the information terminal 80 notifies the abnormality corresponding to the second abnormality information. For example, the information terminal 80 notifies the abnormal position corresponding to the second abnormal information as notification of the abnormality corresponding to the second abnormal information (specifically, for example, notification that the stove main body 1A is in an abnormal position, or , notification that the stove body 1A or the relay terminal 70 is in an abnormal position). Furthermore, the information terminal 80 notifies of a coping method corresponding to the second abnormality information. Examples of the notification of the coping method corresponding to the second abnormality information include "communication error", "check if the gas stove 1 is powered on", and "bluetooth (registered) between relay terminal 70 and gas stove 1". The display unit 82 may be caused to display a message such as "(trademark) communication is obstructed".

If a communication error occurs when information is sent from the gas stove 1 to the relay terminal 70 (for example, when sending a fire extinguishing command or a fire extinguishing complete command), the gas stove 1 may malfunction or communication may occur using the Bluetooth (registered trademark) communication method or the like. is assumed to be disconnected. Therefore, the relay terminal 70 receives the response information (for example, the fire extinguishing command or extinguishing completion command) is not received, abnormality information (third abnormality information) is transmitted to the server 90 . When the server 90 receives the third abnormality information from the relay terminal 70, the server 90 transmits the fourth intermediate information to the information terminal 80, and displays an indication that the communication between the gas stove 1 and the relay terminal 70 is abnormal. Let 80 do it. When the information terminal 80 (second terminal) receives the fourth intermediate information from the server 90, the information terminal 80 notifies an abnormality corresponding to the fourth intermediate information (notices an abnormality corresponding to the third abnormality information). For example, the information terminal 80 notifies an abnormality position corresponding to the fourth intermediate information (specifically, a stove A notification that the main body 1A is in an abnormal position, or a notification that the stove main body 1A or the relay terminal 70 is in an abnormal position).

If a communication error occurs when information is sent from the relay terminal 70 to the server 90 (for example, when a stove operation result notification is sent), it is assumed that communication using the WiFi (registered trademark) communication method or the like is disconnected. . Therefore, if information (for example, stove operation result notification) is not transmitted from the relay terminal 70 within a certain period of time after the information is transmitted to the relay terminal 70 (for example, after transmission of the fire extinguishing request notification), the server 90 sends the information terminal 80 to indicate that the communication is abnormal, and display that the communication between the relay terminal 70 and the server 90 is abnormal. For example, the information terminal 80 causes the display unit 82 to perform the confirmation display.

If a communication error occurs during transmission of information from the server 90 to the information terminal 80 (for example, during transmission of information indicating that fire extinguishing is in progress or that fire extinguishing has been completed), communication between the information terminal 80 and the server 90 is cut off. It is assumed that Therefore, the information terminal 80 receives information from the relay terminal 70 (for example, a fire extinguishing notification or a fire extinguishing If the information indicating completion (third intermediate information) is not transmitted, the display unit 82 is made to display that the communication between the information terminal 80 and the server 90 is abnormal. For example, the information terminal 80 causes the display unit 82 to perform the confirmation display.

Next, the control performed by each device of the gas stove 1, the relay terminal 70, and the information terminal 80 will be described in detail.
First, control performed by the information terminal 80 will be described. The processing shown in FIG. 7 is processing executed by the control circuit 81 in the information terminal 80 . The control circuit 81 detects that an operation for remotely controlling the gas stove 1 (an operation for transmitting a command to the gas stove 1) has been performed on the operation unit 83 while the above-described cooking application is activated. (step S11), the process of FIG. 7 is started. The information terminal 80 transmits operation information corresponding to the predetermined operation to the server 90 in response to a predetermined operation performed on the operation unit 83 . For example, the information terminal 80 transmits a fire extinguishing operation instruction including a fire extinguishing instruction to the server 90 when a fire extinguishing instruction operation (operation for instructing extinguishing of the gas burners 51, 52, 53, and 54) is performed on the operation unit 83. . 7, the second control is started by the control circuit 10 and the control circuit 71 of the gas stove 1, and the information terminal 80 and the relay terminal 70 are connected by the first wireless communication method or the second wireless communication method. It shall be performed in a state where wireless communication can be performed. In subsequent step S<b>12 , the control circuit 81 transmits to the server 90 an operation instruction (for example, a fire extinguishing instruction for one of the stove units 4</b>A, 4</b>B, 4</b>C and the grill 3 ) via the communication unit 84 . When the server 90 receives the operation information transmitted from the information terminal 80 , the server 90 transmits first intermediate information corresponding to the operation information to the relay terminal 70 . For example, the server 90 transmits the fire extinguishing request notification including the fire extinguishing instruction when receiving the fire extinguishing request notification.

Steps S11 and S12 correspond to an example of "the step of causing the communication section 84 to transmit operation information to the server 90 when a predetermined operation is performed on the operation section 83". Specifically, a fire extinguishing instruction operation (operation for instructing extinguishing of the gas burners 51, 52, 53, and 54) is performed on the operation unit 83, and a fire extinguishing operation instruction including the extinguishing instruction is transmitted to the server 90. is.

In the subsequent step S13, the control circuit 81 causes the display section 82 to display that the operation command is being transmitted. In the following step S14, control circuit 81 determines whether or not information (fourth intermediate information) indicating that communication is abnormal has been received from server 90 or not. When the information terminal 80 receives information indicating that there is a communication abnormality, the information terminal 80 notifies that at least one of the first terminal and the main body of the stove is abnormal in step S15. If the control circuit 81 determines in step S14 that it has received information indicating that the communication is abnormal from the server 90, it proceeds to Yes to determine whether the communication between the relay terminal 70 and the gas stove 1 or the gas stove 1 is abnormal. We will notify you to that effect. Specifically, the control circuit 81 causes the display unit 82 to perform the confirmation display. After step S15 is performed, the control circuit 81 terminates the processing of FIG.

When the control circuit 81 determines in step S14 that the information (fourth intermediate information) indicating that the communication is abnormal has not been received from the server 90, the process proceeds to No, and in step S16, the gas stove 1 performs an operation related to the operation command. is being executed from the server 90 or not. If the control circuit 81 determines that it has received the notification that the gas stove 1 is executing the operation related to the operation command, it proceeds to Yes and performs step S18. On the other hand, if the control circuit 81 determines that the gas stove 1 has not received the notification that the operation related to the operation command is being executed, the process proceeds to No, and in step S17, the operation command performed in step S12 is executed. It is determined whether or not a predetermined time (for example, 10 seconds) has elapsed from the time of transmission (whether timeout has occurred). When the control circuit 81 determines that the timeout has occurred, the process proceeds to Yes and performs step S18. On the other hand, when the control circuit 81 determines that the timeout has not occurred, it proceeds to No, and performs step S16 again.

The control circuit 81 causes the display unit 82 to switch the display in step S18. Specifically, the control circuit 81 causes the display unit 82 to transition to the screen (see FIG. 6) that displays the state of the gas stove 1, as described above. For example, as shown in FIG. 6, the display unit 82 displays " ?” is displayed.

In subsequent step S19, control circuit 81 determines whether or not a notification regarding the completion of fire extinguishing has been received from server 90 or not. If the control circuit 81 determines that the notification regarding the completion of extinguishing has been received from the server 90, the control circuit 81 proceeds to Yes and performs step S20. On the other hand, if the control circuit 81 determines that the notification regarding the completion of fire extinguishing has not been received from the server 90, it proceeds to No, and repeats step S21 until it determines that the notification regarding the completion of extinguishing has been received from the server 90. In step S21, the control circuit 81 determines whether or not a predetermined time (for example, 5 minutes) has passed since the transmission of the operation command in step S12 (whether timeout has occurred). When the control circuit 81 determines that the timeout has occurred, the process proceeds to Yes and performs step S22. On the other hand, when the control circuit 81 determines that the timeout has not occurred, the process proceeds to No, and the step S19 is performed again. The reporting unit 85 reports an abnormality when the information terminal 80 does not receive the third intermediate information within a first period of time after the operation information is transmitted from the information terminal 80 to the server 90 . In step S22, the control circuit 81 causes the display unit 82 to display, for example, that communication between the information terminal 80 and the server 90 is abnormal. Specifically, the information terminal 80 causes the display unit 82 to perform the confirmation display. In addition, as notification to the effect that the communication between the information terminal 80 and the server 90 is abnormal, a message to the effect that the communication between the information terminal 80 and the server 90 is abnormal is displayed on the display unit 82, A picture or the like indicating that the communication between the information terminal 80 and the server 90 is abnormal may be displayed. Alternatively, a lamp (not shown) may emit light, or vibration may be used to notify the user. Information indicating that communication between the information terminal 80 and the server 90 is abnormal may be transmitted to the external device via the communication unit 84 . After step S22 is performed, the control circuit 71 terminates the processing of FIG.

When the information terminal 80 receives the third intermediate information transmitted from the server 90, the information terminal 80 performs notification corresponding to the reception of the third intermediate information. For example, the control circuit 81 performs notification corresponding to the reception of the third intermediate information on condition that the third intermediate information is received via the communication unit 84 . That is, the control circuit 81 performs notification corresponding to the reception of the third intermediate information when the third intermediate information is received via the communication unit 84 or after a predetermined time from the time when the third intermediate information is received. For example, when the information terminal 80 receives information indicating the completion of fire extinguishing, the reporting unit 85 causes the display unit 82 to display that the fire extinguishing is completed (second display). In step S<b>20 , the control circuit 81 causes the display section 82 to update the display of the state of the gas stove 1 . For example, as shown in FIG. 6, the display unit 82 displays "extinguishing" corresponding to each of the stove sections 4A, 4B, 4C and the grill 3 when each of the stove sections 4A, 4B and 4C and the grill 3 has been extinguished. ” is displayed. Step S20 corresponds to an example of "the step of causing the notification unit 85 to perform notification corresponding to the reception of the third intermediate information when the communication unit 84 receives the third intermediate information transmitted from the server 90". After step S20 is performed, the control circuit 81 terminates the processing of FIG.

Next, control performed by the relay terminal 70 will be described. The processing shown in FIG. 8 is processing executed by the control circuit 71 in the relay terminal 70 . The control circuit 71 starts the processing of FIG. 8 by activating the cooking application described above. 8 is performed in a state where the control circuit 10 and the control circuit 71 of the gas stove 1 have started the second control.

In step S31, the control circuit 71 determines whether or not an instruction to the gas stove 1 (an operation instruction, such as a fire extinguishing instruction for one of the stove units 4A, 4B, 4C and the grill 3) has been input from the server 90. to decide. The control circuit 71 controls the second communication unit 76 so that, when an instruction (command) is input to the second communication unit 76, the instruction is wirelessly transmitted to the gas stove 1 using the second wireless communication method. When the control circuit 71 determines that an instruction to the gas stove 1 has been input from the server 90, it performs step S32. On the other hand, when the control circuit 71 determines that the instruction to the gas stove 1 has not been input from the server 90, it repeats step S31 until it determines that the instruction has been input. When relay terminal 70 receives the first intermediate information transmitted from server 90 , relay terminal 70 transmits instruction information corresponding to the first intermediate information to gas stove 1 . For example, when receiving a fire extinguishing request notification including a fire extinguishing instruction, the relay terminal 70 transmits a fire extinguishing request command including the fire extinguishing instruction to the gas stove 1 . In step S32, the control circuit 71 sends commands to the gas stove 1 (for example, each stove section 4A, 4B, 4C, grill Send a fire extinguishing command requesting extinguishing of any of 3). Furthermore, when the first communication unit 75 receives the first intermediate information transmitted from the server 90, the control circuit 71 causes the display unit 72 to perform a first display corresponding to the reception of the first intermediate information. For example, when the control circuit 71 receives a fire extinguishing request notification from the server 90, the first display corresponding to the reception of the fire extinguishing request notification (a display indicating that a command based on the operation of the information terminal 80 has been received) is displayed on the display unit 72. let it happen The “display indicating that a command based on the operation of the information terminal 80 has been received” may be, for example, a message indicating that the command has been received, or may be a pattern indicating that the command has been received. . For example, when causing the display unit 72 to display the first display corresponding to the reception of the fire extinguishing request notification, a message such as "Fire extinguishing request has been made from the outside" may be displayed. may be displayed.

In subsequent step S33, the control circuit 71 receives an execution command (for example, a command notifying that any one of the stove units 4A, 4B, 4C and the grill 3 is being extinguished) from the gas stove 1. determine whether or not If the control circuit 71 determines that it has received the in-execution command, it performs step S36. On the other hand, if the control circuit 71 determines that the command under execution has not been received, the process proceeds to No, and in step S34, a predetermined time (for example, 10 seconds) has elapsed since the command was transmitted in step S32. (whether timeout). If the control circuit 71 determines that the timeout has occurred, it proceeds to Yes and performs step S35. On the other hand, when the control circuit 71 determines that the timeout has not occurred, it proceeds to No, and performs step S33 again.

The control circuit 71 transmits abnormality information to the server 90 when response information is not received within a second period of time after the instruction information (step S32) is transmitted from the relay terminal 70 to the gas stove 1. FIG. In step S<b>35 , the control circuit 71 transmits information (abnormality information) to the effect that the communication is abnormal to the server 90 . That is, the control circuit 71 transmits communication between the relay terminal 70 and the gas stove 1 or information indicating that the gas stove 1 is abnormal. Server 90 transmits the fourth intermediate information to information terminal 80 when abnormal information is received from relay terminal 70 . After step S35 is performed, the control circuit 71 terminates the processing of FIG.

When the information on the state of the gas stove 1 is wirelessly transmitted from the gas stove 1, the control circuit 71 displays a display corresponding to the information on the state of the gas stove 1 (a display indicating that a command is being executed, which will be described later), or a message indicating that the command has been completed. ) is displayed on the display unit 72 . For example, in step S36, the control circuit 71 causes the display unit 72 to display (display according to the state information) that the gas stove 1 is executing a command (for example, a fire extinguishing request command). The display in step S36 may be a display of character information indicating that the gas stove 1 is executing a command (for example, a fire extinguishing request command), or may be a pictorial display to that effect, or a combination of these. may be In subsequent step S37, the control circuit 71 transmits information to the information terminal 80 via the server 90 that the fire is being extinguished.

In subsequent step S38, the control circuit 71 determines whether or not a completion command (for example, a command notifying completion of extinguishing one of the stove units 4A, 4B, 4C and the grill 3) has been received from the gas stove 1. to decide. When the control circuit 71 determines that the completion command has been received, the control circuit 71 performs step S39. On the other hand, when determining that the completion command has not been received, the control circuit 71 repeatedly performs step S38 until it determines that the completion command has been received.

In step S39, the control circuit 71 causes the display unit 72 to display that the gas stove 1 has finished extinguishing (display corresponding to the state information). The display in step S39 may be a display of text information to the effect that extinguishing of the gas stove 1 has been completed (for example, to the effect that all gas burners are extinguished), or may be a pictorial display to that effect. , may be used in combination. In subsequent step S40, the control circuit 71 transmits information to the information terminal 80 via the server 90 to the effect that the fire has been extinguished. When receiving the response information transmitted from the gas stove 1 , the relay terminal 70 transmits second intermediate information corresponding to the response information to the server 90 . For example, when the relay terminal 70 receives response information including information indicating completion of fire extinguishing, the relay terminal 70 transmits information including information indicating completion of extinguishing (stove operation result notification) to the server 90 . When server 90 receives the second intermediate information transmitted from relay terminal 70 , server 90 transmits third intermediate information corresponding to the second intermediate information to information terminal 80 . When the server 90 receives information including information indicating completion of fire extinguishing (stove operation result notification), the server 90 transmits to the information terminal 80 information indicating completion of fire extinguishing including information indicating completion of fire extinguishing. After step S40 is performed, the control circuit 71 terminates the processing of FIG.

Next, control performed by the gas stove 1 will be described. The processing shown in FIG. 9 is processing executed by the control circuit 10 in the gas stove 1. FIG. The process of FIG. 9 is started by starting the second control by the control circuit 10 and the control circuit 71, for example.

In step S51, the control circuit 10 determines whether or not a command (for example, a fire extinguishing command requesting extinguishing any one of the stove units 4A, 4B, 4C and the grill 3) has been transmitted from the relay terminal 70 or not. When the control circuit 10 determines that the command has been transmitted from the relay terminal 70, the control circuit 10 performs step S52. On the other hand, when the control circuit 10 determines that the command has not been transmitted from the relay terminal 70, the step S51 is repeated. In step S<b>52 , control circuit 10 receives a command from relay terminal 70 .

When an instruction (command) is wirelessly transmitted from the information terminal 80, the control circuit 10 causes the gas stove 1 to perform an operation according to the instruction. When receiving the instruction information transmitted from the relay terminal 70 , the gas stove 1 performs a corresponding operation corresponding to the instruction information and transmits response information to the relay terminal 70 . For example, the gas stove 1 performs an operation to extinguish the gas burners 51, 52, 53, and 54 when instruction information including an extinguishing instruction is received, and extinguishes the gas burners 51, 52, 53, and 54 when extinguishing is detected. Send a fire extinguishing complete command containing information indicating completion. At step S53, the control circuit 10 performs an operation corresponding to the command received at step S52. The control circuit 10 stores operations corresponding to commands in advance. For example, the control circuit 10 stores an operation for extinguishing any one of the stove units 4A, 4B, 4C and the grill 3 in response to a fire extinguishing command. Specifically, the control circuit 10 stores an operation for extinguishing the stove portion 4A in response to a fire extinguishing command including a command to extinguish the stove portion 4A. An operation for extinguishing the stove 4B is stored correspondingly, and an operation for extinguishing the stove 4C is stored in response to a fire extinguishing command including a command for extinguishing the stove 4C, and a command for extinguishing the grill 3 is stored. An operation of extinguishing the fire of the grill 3 in response to the extinguishing command is stored. Therefore, for example, when the control circuit 10 receives a fire extinguishing command including a command to extinguish the stove portion 4A, the control circuit 10 extinguishes the fire of the stove portion 4A.

The control circuit 10 controls the communication unit 11 to wirelessly transmit information on the state of the gas stove 1 (executing command, completion command, etc., which will be described later) to the relay terminal 70 during the first control. In step S54, the control circuit 10 transmits to the relay terminal 70 an in-execution command (for example, a command indicating that one of the stove units 4A, 4B, 4C and the grill 3 is being extinguished). . At subsequent step S55, the control circuit 10 determines whether or not the condition for completing the operation corresponding to the command is met. For example, when the electromotive force generated by any of the thermocouples provided in each of the stove units 4A, 4B, 4C and the grill 3 falls below a predetermined threshold, the conditions for completing extinguishing on the stove or grill provided with the thermocouple is established. When the control circuit 10 determines that the completion condition is satisfied, the control circuit 10 performs step S56. On the other hand, when the control circuit 10 determines that the completion condition is not satisfied, it repeats step S55. In step S56, the control circuit 10 transmits to the relay terminal 70 a completion command (for example, a command notifying that the fire extinguishing of one of the stove units 4A, 4B, 4C and the grill 3 has been completed). After step S56 is performed, the control circuit 10 terminates the processing of FIG.
