Further, a wireless LAN router 6 (first router) is installed indoors, and the wireless LAN router 6 is connected to an Internet network (communication network). The wireless LAN router 6 functions as a master unit of the wireless LAN, and a plurality of wireless LAN slave units can be wirelessly connected. In order to establish a wireless link between each wireless LAN slave unit and the wireless LAN router 6, it is necessary to set wireless LAN connection information including the SSID and the encryption key of the wireless LAN router 6 in each slave unit. In order to facilitate such setting work, the wireless LAN router 6 has a WPS (Wi-Fi Protected Set) function, pushes the WPS button provided on each slave unit, and prepares for the wireless LAN router 6. By pushing the WPS button, a wireless link between the slave unit and the wireless LAN router 6 is established. Each slave unit can also be configured to manually set the wireless LAN connection information, and such manual setting operation can be performed using a user terminal 3 or a personal computer that is communicably connected to the slave unit. It can also be configured as.

The user terminal 3 and the communication adapter 4 can operate as a wireless LAN slave unit, and by setting the wireless LAN connection information consisting of the SSID and the encryption key of the wireless LAN router 6, the wireless link with the wireless LAN router 6 can be established. It is established and can connect to the Internet via the wireless LAN router 6. The user terminal 3 can store and hold the wireless LAN connection information of a plurality of wireless LAN base units such as the public wireless LAN base station 10 (second router), and wirelessly uses the wireless LAN connection information specified by the user. When a wireless link with the LAN master unit is established and the wireless link with the currently connected wireless LAN master unit is disconnected, the wireless LAN master unit is searched for based on multiple wireless LAN connection information. It is configured to automatically establish a wireless link. When it is not possible to connect to any of the stored wireless LAN connection information, the user terminal 3 is configured to connect to the Internet network via a mobile communication network (not shown) such as a 4G line or a 3G line. ing.

The communication adapter 4 has a built-in wireless communication controller (not shown) for performing wireless communication with the wireless LAN router 6 using a predetermined communication protocol (for example, IEEE802.11n / IEEE802.11g / IEEE802.11b, etc.). As the wireless communication controller, for example, a custom-programmable commercially available wireless LAN module can be used, and this wireless communication controller can function as the main control unit of the communication adapter 4. It should be noted that a microprocessor different from the wireless communication controller can be implemented as the main control unit.

When the wireless link with the wireless LAN router 6 is established, the control unit of the communication adapter 4 automatically connects to the cloud server 2a and transmits various system configuration information at the time of connection. The various system configuration information may include the serial number (S / N) of the communication adapter 4 and BSSID1 (identification information unique to the first router) of the wireless LAN router 6 acquired by communication with the wireless LAN router 6. it can. The communication between the wireless LAN router 6 and the cloud server 2a can be performed by TCP / IP communication, and the system configuration information can be included in the data unit of the TCP packet. The identification information unique to the first router can be included in neither the IP header of the TCP / IP communication nor the TCP header.

Further, the control unit of the communication adapter 4 has an information collection function for collecting various information about the hot water supply system 1 stored and held by the control unit by communication with the water heater 1a and the remote controller 1b, and a cloud server for the collected information. It may have an information transmission function to be transmitted to 2a. Various information transmitted to the cloud server 2a is also provided to the application server 2b as needed, and is used for various remote monitoring services and remote control services for the user terminal 3.

Each of these functions can be realized by the functions initially implemented in the wireless communication controller or by custom programming of the wireless communication controller, and the timing at which each function is executed can be appropriately designed. For example, the information collection function and the information transmission function may be executed periodically at predetermined time intervals, or may be executed when an information transmission request from the cloud server 2a is received. Good.

Further, in the present embodiment, when the user logs in to the application server 2b from the user terminal 3 such as a smartphone using his / her own user account, the user terminal 3 is connected to the currently connected wireless LAN base unit (wireless in FIG. 1). It is configured to acquire the BSSID of the wireless LAN master unit by communicating with the LAN router 6) and transmit it to the application server 2b. When the application server 2b receives the BSSID from the user terminal 3, the application server 2b cooperates with the cloud server 2a to confirm the match with the BSSID received from the communication adapter 4 associated with the user account.

When the communication adapter 4 and the user terminal 3 are wirelessly connected to the same wireless LAN router 6, as shown in FIG. 1, the BSSID 1 received from the user terminal 3 and the BSSID 1 received from the communication adapter 4 match. For confirmation, the application server 2b transmits a BSSID match notification (restriction release command) to the user terminal 3.

As shown in FIG. 2, when the user terminal 3 is wirelessly connected to a public wireless LAN base station outside the home, the BSSID 2 received from the user terminal 3 and the BSSID 1 received from the communication adapter 4 do not match. The application server 2b transmits a BSSID mismatch notification (restriction command) to the user terminal 3.

The user terminal 3 that has received the BSSID mismatch notification is configured to be more restricted in the content of the operation command that can be sent to the hot water supply system 1 via the management system 2 than when the BSSID match notification is received. For example, when the BSSID match notification is received, a hot water supply temperature setting operation command (first operation command) exceeding a predetermined temperature (for example, 50 ° C.) and a hot water supply temperature setting operation command within a range of the predetermined temperature or less (for example, 50 ° C.) The second operation command) is possible, but when the BSSID mismatch notification is received, the hot water supply temperature setting operation command can be input within the range of the predetermined temperature or less, but the hot water supply temperature setting operation exceeds the predetermined temperature. It is configured so that commands cannot be input. Further, when the BSSID match notification is received, both the hot water supply operation ON operation command (first operation command) and the hot water supply operation OFF operation command (second operation command) can be input. On the other hand, when the BSSID mismatch notification is received, the hot water supply operation OFF operation command can be input, but the hot water supply operation ON operation command cannot be input.

When the user inputs a desired operation command to the user terminal 3, the operation command is first transmitted to the application server 2b. When the application server 2b receives the operation command from the user terminal 3, the application server 2b transmits the operation command to the cloud server 2a. When the cloud server 2a receives the operation command from the application server 2b, the cloud server 2a transmits the operation command to the communication adapter 4 of the hot water supply system 1. As a result, the operation command input to the user terminal 3 is immediately supplied to the hot water supply system 1 via the management system 2. The operation command does not have to have the same command format and format in each transmission / reception route, and the expression format of each operation command may be various depending on the communication protocol and other circumstances of each transmission / reception route.

When the communication adapter 4 receives the hot water supply temperature setting operation command, it transmits an operation command for setting the hot water supply temperature specified by the command to the water heater 1a or the remote controller 1b, whereby the hot water supply temperature setting change operation is performed. To. Here, the operation of changing the setting of the hot water supply temperature exceeding a predetermined temperature is referred to as a first operation, and the function of performing the first operation is referred to as a first remote control function. Further, the operation of changing the setting of the hot water supply temperature below the predetermined temperature is referred to as a second operation, and the function of performing the second operation is referred to as a second remote control function. In this case, the first operation command may be a command for directly designating the hot water supply temperature to be changed and set, such as "set to 60 ° C.", or 1 when the current hot water supply temperature setting is 50 ° C. It may be a command to raise the set temperature.

According to the remote operation system according to the first embodiment, when the user terminal 3 is wirelessly connected to the home wireless LAN router 6, all the operation commands that can be operated from the user terminal 3 can be input. For example, the user terminal 3 can be used to perform various operations of the water heater 1a while relaxing in the living room. On the other hand, when the user terminal 3 is wirelessly connected to the public wireless LAN base station 10 or connected to the 3G or 4G mobile communication network, such as when going out, hot water is supplied to the unsafe side as described above. Since it is restricted so that an operation command that changes the state of the system 1 cannot be input, safety can be ensured.

The present invention is not limited to the above embodiment, and the design can be changed as appropriate. For example, when the heat source system is a hot water supply system, the first operation may be all operations for changing the hot water supply set temperature. In addition, when the heat source system is a bath device having a hot water beam function (including an automatic reheating function) that performs hot water filling in the bathtub at the hot water filling set temperature, the first operation is to set the hot water beam set temperature. It may be an operation to change. When the heat source system is a heating device such as a hot water floor heating system or a gas fan heater, the first operation may be an operation to start the operation of the heating device or an operation to stop the operation of the heating device. May be good. When the heat source system is a heating device, the first operation may be an operation of changing the heating set temperature of the heating device or an operation of changing the heating capacity.

Further, in the first embodiment, when the user terminal 3 is connected to the public wireless LAN base station 10, the operation commands that can be input by the user terminal 3 are restricted, but the operation commands relayed by the management system 2 are restricted. You can also do it. That is, when the match between the BSSID received from the hot water supply system 1 and the BSSID received from the user terminal 3 can be confirmed, both the first and second operation commands received from the user terminal 3 are transmitted to the hot water supply system 1. The management system 2 is configured to do so. On the other hand, as shown in FIG. 3, when the match between the BSSID 1 received from the hot water supply system 1 and the BSSID 2 received from the user terminal 3 cannot be confirmed, the second operation command is transmitted to the hot water supply system 1, but the user terminal. The management system 2 can also be configured so that the first operation command received from 3 is not transmitted to the hot water supply system 1 (for example, transmission of the first operation command from the application server 2b to the cloud server 2a is prohibited).

Further, as shown in FIG. 4, when the user terminal 3 is connected to the public wireless LAN base station 10, the first remote control function of the communication adapter 4 is disabled, and only the second remote control function is enabled. It can also be configured as. That is, when the management system 2 cannot confirm the match between the BSSID 1 received from the hot water supply system 1 and the BSSID 2 received from the user terminal 3, the management system 2 notifies the hot water supply system 1 of the BSSID mismatch (limits the first remote operation function). It can be configured to send a restriction command). When the hot water supply system 1 receives the BSSID mismatch notification from the management system 2, the hot water supply system 1 can be configured so that the above-mentioned first operation is not performed by disabling the first remote control function.
