FIG. 1 shows a network system according to an embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of a communication adapter according to an embodiment of the present invention.

  The communication adapter in FIG. 1 includes a communication unit 101, an interface unit 102, a controller unit 103, a program holding unit 104, a protocol control unit 105, a setting verification unit 106, a control reception unit 107, a setting reception unit 108, and a storage unit 110.

  The communication unit 101 is connected to a wireless or wired network, and communicates with an external device such as a terminal or a server via the network. The network includes a wireless LAN, a wired LAN, and a PAN.

  The interface unit 102 includes an interface connected to a device such as a home appliance. The interface unit 102 transmits and receives signals to and from the connected device according to the control of the controller unit 103. The connection between the interface unit 102 and the device may be wired or wireless.

  The controller unit 103 controls the interface unit 102 to perform communication (such as serial communication) with the device. The controller unit 103 is configured of, for example, one or more controller chips or the like (UART, SPI, I2C, GPIO, PWM, etc.). The setting of the controller unit 103, that is, which controller to use, and the parameters (bit rate, master / slave, etc.) of each controller can be set by the setting accepting unit 108. In order to properly communicate with the device connected to the interface unit 102, it is necessary to use a controller and parameters adapted to the device. If communication with the device is not working properly, it is necessary to change the controller to be used or its parameters. When the parameter of each controller is fixed, the setting change of the controller unit 103 is equivalent to the change of the controller to be used. In the following description, it is mainly assumed that the parameters of each controller are fixed, and the setting change of the controller unit 103 corresponds to the change of the controller to be used. However, when the parameters of the controller can be changed, the same controller When changing the parameter while using the parameter, the setting change of the controller unit 103 may be included.

  The program holding unit 104 stores one or more device control protocols. When the device connected to the interface unit 102 is a home appliance, a protocol for home appliance control is assumed as an example of a protocol for device control. The program holding unit 104 can be configured by a memory, a storage, or the like. The device control protocol may be acquired from a server on an external network and stored in the program holding unit 104.

  The protocol control unit 105 controls a device connected to the interface unit 102 using one of the protocols stored in the program storage unit 104. The setting of the protocol control unit 105, that is, which protocol to use, and the parameters of the protocol can be set by the setting accepting unit 108. In order to control the device normally, it is necessary to use a protocol adapted to the device or to set parameters adapted to the device in the protocol. If there is a protocol error with the device, that is, if the device can not be controlled properly, it is necessary to change the protocol to be used or change the parameter setting of the protocol. In addition, when the parameter of each protocol is fixed, the setting change of the controller unit 103 corresponds to the change of the protocol to be used. In the following description, it is assumed that the parameters of each protocol are fixed and the setting change of the protocol control unit 105 corresponds to the change of the protocol to be used, but if the parameters of the protocol can be changed, the same protocol When changing the parameter while using the parameter, the setting change of the protocol control unit 105 may be included.

  The setting verification unit 106 verifies whether the current setting (the current setting of the protocol control unit and the current setting of the controller unit 103) is correct, that is, the current setting conforms to the connected device. More specifically, the setting verification unit 106 confirms whether or not the controller unit 103 is operating normally in the current setting. If communication with the device is not operating normally, it is necessary to change the setting of the controller unit 103 (here, change the controller to be used). Enable 108. Further, when the controller unit 103 is normal, the setting verification unit 106 confirms whether the protocol control unit 105 is operating normally. If there is a protocol error with the device, the protocol control unit 105 is not operating normally, and it is necessary to change the setting of the protocol control unit 105 (here, change of the protocol to be used). In order to enable setting of the protocol control unit 105, the setting accepting unit 108 is enabled.

  The storage unit 110 stores setting information of the communication adapter. The setting information of the controller unit 103 and the protocol control unit 105 currently set in the communication adapter is stored. Further, the setting information of the communication unit 101 is stored. As an example of setting information of the communication unit 101, there may be information of parameters (encryption key, SSID, etc.) of a wireless LAN (WiFi). When it is necessary to set user information such as a user account in the communication adapter, the user information is stored. In addition, the storage unit 110 stores device information of the connection destination device. The device information includes, for example, a device type, a device ID, a model number, a manufacturer, a serial number, or a plurality of these.

  The setting verification unit 106 acquires device information (model ID or device ID or both of them) of the device through the protocol control unit 105, and whether or not they match those stored in the storage unit 110, That is, it may be checked whether it is registered in the storage unit 110. If the device is not registered, there is a possibility that the connected device has been replaced. Therefore, the setting verification unit 106 enables the setting accepting unit 108, and the device assumed to be currently connected to the user is assumed by the user. It may be confirmed whether the device matches. On the other hand, when the acquired device information is registered in storage unit 110 and protocol control unit 105 and controller unit 103 are normal, it is determined that the setting of the communication adapter is normal, and control reception unit 107 is valid. Make it Even if they do not match, the control reception unit 107 may be enabled as long as it is confirmed that the controller unit 103 and the protocol control unit 105 are operating normally.

  The control reception unit 107 receives a control message instructing control of a device from a terminal via the communication unit 101, and outputs the control message to the protocol control unit 105. The protocol control unit 105 causes the controller unit 103 to output a control instruction corresponding to the control message to the device by controlling the controller unit 103 based on the control message.

  The setting accepting unit 108 provides the terminal with screens for various settings when the terminal accesses the communication adapter. The screen provided to the terminal is instructed by the setting verification unit 106, for example. For example, when the setting verification unit 106 determines that the setting of the controller unit 103 does not conform to the device, the setting accepting unit 108 provides a screen for setting of the controller unit 103 so that the setting is performed by the device. Inform that it does not conform to The setting reception unit 108 receives a setting message for the controller unit 103 from the terminal, and sets the controller unit 103 based on the setting message. The setting of the controller unit 103 includes setting or changing of a controller to be used, or changing of parameters of a currently used controller.

  Further, when the setting verification unit 106 determines that the setting of the protocol control unit 105 does not conform to the device, the setting reception unit 108 provides the terminal with a setting screen for the protocol control unit 105 to the terminal. Notifies that the setting does not conform to the device. The setting reception unit 108 receives a setting message for the protocol control unit 105 from the terminal via the communication unit 101, and sets the protocol control unit 105 based on the setting message. The setting of the protocol control unit 105 includes setting or changing the protocol to be used, or changing the parameter of the currently used protocol. There are various setting screens other than those described here.

  FIG. 2 is a flow chart showing an operation example of the communication adapter of FIG.

  The setting verification unit 106 confirms whether the initial setting of the communication adapter is completed (step 201). The completion of the initialization means that the settings of the controller unit 103 and the protocol control unit 105 are made. The setting of the communication unit 101 and the setting of the user account may be included. Among these setting items, if there is an item whose initial setting is not completed, it is judged that the initial setting is necessary (step 202), and the setting accepting unit 108 is made effective (step 203). When the terminal receives access in this state, setting accepting unit 108 presents a screen for prompting the user for initial setting on the terminal. The setting accepting unit 108 performs initial setting based on the setting message input by the user via the screen. FIG. 3 shows an example of an initial setting screen. An example of setting each setting item on the initial setting screen is shown in FIG.

  If the initial setting has been completed, the setting verification unit 106 checks whether the controller unit 103 is operating normally with the connected device (step 204). For example, when a control command is transmitted to the device from the controller unit 103 as a test, and no response is returned to the transmitted control command, or the returned data can not be decoded normally (the data of the broken byte string is It is determined that the controller unit 103 is not normal, etc.). If the controller unit 103 is not operating normally, it is determined that the setting change of the controller unit 103, that is, the controller currently being used in the controller unit 103 needs to be changed to another controller (step 205). Then, the setting accepting unit 108 is validated (step 203). When the terminal receives an access in this state, setting accepting unit 106 presents a screen for prompting the user of the setting of controller unit 103 to the terminal. The setting accepting unit 108 changes the setting of the controller unit 103 based on the setting message input from the user. FIG. 5 shows an example of a screen for setting the controller unit. The user can click the change button to change the setting of the controller unit 103 (change the controller to be used). When there are a plurality of controller candidates to be changed, a plurality of candidates may be displayed and selected by the user. In the example of the figure, there is one candidate of the controller to be changed, and the information of the candidate is displayed.

  If the controller unit 103 is operating normally, the setting verification unit 106 checks whether the protocol control unit 105 is operating normally with the device (step 206). For example, the setting verification unit 106 operates the protocol control unit 105 on a test basis to confirm whether control according to the instructed operation has been performed. For example, a predetermined protocol message is sent to the device, and it is confirmed whether or not a desired response message is returned. If the protocol control unit 105 is not operating normally, that is, if a protocol error occurs, it is determined that the protocol to be used needs to be changed (step 207), and the setting accepting unit 108 is made effective. (Step 203). When the terminal accesses the communication adapter in this state, setting accepting unit 108 presents a screen for prompting the user to set the protocol control unit (change the protocol) to the terminal, and the setting message input from the user Configure the protocol based on. FIG. 6 shows an example of a screen for setting a protocol control unit. The user can change the protocol by clicking on the change button. When there are a plurality of candidates for the protocol to be changed, a plurality of candidates may be displayed and selected by the user. In the example of the figure, there is one candidate of the protocol to be changed, and the information of the candidate is displayed.

  When the protocol control unit 105 is operating normally, the setting verification unit 106 has registered in the storage unit 110 the device information (model ID or device ID, or both of them) obtained through the protocol control unit 105. Check if it matches the one (step 209). If they do not match, it is determined that the connected device may have been replaced (step 210). Then, the setting accepting unit 108 is enabled to notify the user of the fact or review the setting (step 203). When there is access from the terminal to the communication adapter in this state, setting accepting unit 108 is a screen including the device information detected through protocol control unit 105 and the device information registered in storage unit 110, ie, a connection. The user is presented with a screen to notify the user that the previous device may have been changed. An example of the presented screen is shown in FIG. The user confirms whether there is no problem in the current registration content of the storage unit 110 based on the screen, and if there is no problem, selects (clicks) the approval button. By prompting the user for approval, it is possible to prevent the device from being controlled without being aware of the change in the model / device. Even when the acquired device information (model information, device ID, etc.) is different from that registered in the storage unit 110, if the protocol control unit 105 and the controller unit 103 are normal, in particular some functions (power supply Equipment can be properly controlled, etc.).

  On the other hand, when the device information detected through the protocol control unit 105 matches the information registered in the storage unit 110, it is determined that the setting of the communication adapter is normal (step 210), and the control reception unit 107 is validated. (Step 211). When the terminal receives an access to the communication adapter in this state, the control receiving unit 107 presents on the terminal a device control screen for operating or controlling the device. An example of a touch panel screen for device control is shown in FIG. The user can input a control instruction to the device on this screen. The terminal transmits a control message according to the user's input to the communication adapter. The protocol control unit 105 receives this control message via the communication unit 101 and the control reception unit 107. The protocol control unit 105 controls the device via the controller unit 103 based on the received control message.

  By the above operation, the setting verification unit detects for which part the setting (initial setting, setting of the controller unit, setting of the protocol control unit, user approval, etc.) is currently required for the user. It is possible to respond only to the setting items that are currently required.

  For example, in the case of merely notifying the user that the setting is not correct, it is difficult to determine which part of the controller unit, the protocol control unit, etc. is incorrect. In the present embodiment, the setting of the controller unit is verified, and if it is incorrect, the user is notified that the setting is incorrect, so that the user can correctly grasp that the setting of the controller unit is incorrect. Further, if the setting of the controller unit is correct, the setting of the protocol control unit is verified next, and if it is incorrect, the user is notified that the setting is incorrect, so that the user can correctly grasp that the setting of the protocol control unit is incorrect. As described above, in the present embodiment, the load on the user who sets the communication adapter can be reduced.

  In the example of the operation flow described above, when it is determined in step 204 that the setting of the controller unit 103 is incorrect, the user is made to select another controller, but the correct controller is automatically estimated from the content of the error. Methods are also possible. For example, an identification model for estimating a controller from error data (corrupted information) is prepared, and the setting verification unit 106 estimates a correct controller from the identification model and the error data, and the setting accepting unit 108 May be proposed to the user. Alternatively, the setting verification unit 106 may automatically set the estimated correct controller setting in the controller unit 103. The model may be constructed by machine learning. That is, it is well known how to prepare many sets of error data and the correct controller and use them as teacher data to construct a model by machine learning. Although the correct controller is estimated here, the same concept may be used to estimate the correct protocol. The estimation using the model may not be performed in the communication adapter, but may be performed by an external estimation device or server that can communicate via the communication unit 101. In this case, the setting verification unit 106 transmits the above error data and the like to the external estimation device or server via the communication unit 101, and receives information on the correct controller settings estimated by the external estimation device or server. do it.

  In the example of the operation flow described above, when it is determined in step 206 that the setting of the protocol control unit is incorrect, the user is made to select another protocol candidate, but from the setting information of the controller unit 103 There are cases where you can narrow down the candidates. For example, in some protocol specifications, specifications of the physical layer (= controller) may be specified. If the current configuration of the controller unit 103 does not match that of a particular protocol specification, that particular protocol can in principle be removed from the candidates. Therefore, protocols other than the specific protocol may be presented to the user as candidates. For example, in a home appliance protocol (provisionally referred to as home appliance protocol A), when a specification based on UART is defined as the specification of the physical layer, the correspondence relationship “UART-> home appliance protocol A” is shown in the controller / protocol correspondence table. Set to. When a UART is selected as the controller unit 103, “home appliance protocol A” is presented to the user as a setting candidate of the protocol control unit 105 from the controller-protocol correspondence table. Also, instead of presenting the specified candidate to the user, the setting verification unit 106 may automatically apply the setting of the candidate to the protocol control unit. When a plurality of candidates exist, one of the settings may be applied, and when the setting after the application is incorrect, another candidate may be selected again and the selected candidate may be applied.
