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 of 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, a PAN and the like.

The interface unit 102 includes an interface for connecting to devices such as home appliances. The interface unit 102 transmits/receives a signal to/from a connected device under 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 (serial communication or the like) with a device. The controller unit 103 is configured by, for example, one or a plurality of controller chips (UART, SPI, I2C, GPIO, PWM, etc.). The setting of the controller unit 103, that is, which controller to use, and parameters (bit rate, master/slave, etc.) of each controller can be set by the setting receiving unit 108. In order to normally communicate with the device connected to the interface unit 102, it is necessary to use a controller and parameters suitable for the device. If the communication with the equipment is not working properly, it is necessary to change the controller used or its parameters. When the parameter of each controller is fixed, changing the setting of the controller unit 103 is equivalent to changing the controller used. In the following description, it is assumed that the parameters of each controller are mainly fixed and the setting change of the controller unit 103 corresponds to the change of the controller to be used. However, when the controller parameters can be changed, the same controller is used. Even if the parameter is changed while using, 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 electric device, a home electric appliance control protocol is assumed as an example of the device control protocol. 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 uses one of the protocols stored in the program storage unit 104 to control the device connected to the interface unit 102. The setting of the protocol control unit 105, that is, which protocol to use, and the parameter of the protocol can be set by the setting reception unit 108. In order to control the device normally, it is necessary to use a protocol suitable for the device or set a parameter suitable for the device in the protocol. If a protocol error occurs with the device, that is, if the device cannot be controlled normally, it is necessary to change the protocol to be used or the parameter setting of the protocol. When the parameters of each protocol are fixed, the setting change of the controller unit 103 corresponds to the change of the protocol 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. However, if the protocol parameters can be changed, the same protocol is used. Even when the parameter is changed while using, the setting change of the protocol control unit 105 may be included.

The setting verification unit 106 verifies whether or not the current settings (the current settings of the protocol control unit and the current settings of the controller unit 103) are correct, that is, whether the current settings are suitable for the connected device. More specifically, the setting verification unit 106 confirms whether the controller unit 103 is operating normally in the current setting. If the 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). Therefore, in order to enable the setting of the controller unit 103, the setting receiving unit Enable 108. In addition, the setting verification unit 106 confirms whether the protocol control unit 105 is operating normally when the controller unit 103 is operating normally. If a protocol error occurs 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 the protocol to be used). The setting reception unit 108 is enabled so that the protocol control unit 105 can be set.

The storage unit 110 stores the 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. The setting information of the communication unit 101 is also stored. As an example of the setting information of the communication unit 101, there may be information on parameters (encryption key, SSID, etc.) of a wireless LAN (WiFi). If user information such as a user account needs to be set in the communication adapter, the user information is stored. The storage unit 110 also 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 manufacturing number, or a plurality of these.

The setting verification unit 106 acquires the device information of the device (model ID or device ID or both of them) through the protocol control unit 105, and whether these match with those stored in the storage unit 110, That is, it may be confirmed whether it is registered in the storage unit 110.
If the device is not registered, the connected device may have been exchanged. Therefore, the setting verification unit 106 enables the setting reception unit 108 so that the device currently connected to the user is assumed by the user. You may confirm whether it matches the device you are using. On the other hand, when the acquired device information is registered in the storage unit 110 and the protocol control unit 105 and the controller unit 103 are normal, the setting of the communication adapter is determined to be normal and the control reception unit 107 is enabled. To Even if they do not match, if it is confirmed that the controller unit 103 and the protocol control unit 105 are operating normally, the control reception unit 107 may be enabled.

The control accepting unit 107 accepts a control message for instructing device control from the terminal via the communication unit 101, and outputs the control message to the protocol control unit 105. The protocol control unit 105 controls the controller unit 103 based on the control message to cause the controller unit 103 to output a control command corresponding to the control message to the device.

The setting reception unit 108 provides the terminal with various setting screens 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 is not suitable for the device, the setting reception unit 108 provides a screen for the setting of the controller unit 103 so that the setting is performed. Notify 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 the controller to be used, or changing the parameter of the controller currently used.

Further, when the setting verification unit 106 determines that the setting of the protocol control unit 105 is not suitable for the device, the setting reception unit 108 provides the terminal with a screen for setting the protocol control unit 105, Notify that the setting is not compatible with 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 protocol currently used. There are various setting screens other than those mentioned here.

FIG. 2 is a flowchart 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 initial setting means that the controller unit 103 and the protocol control unit 105 have been set. The setting of the communication unit 101 and the setting of the user account may also be included. If some of these setting items have not been initialized, it is determined that initial setting is necessary (step 202) and the setting accepting unit 108 is enabled (step 203). When there is access from the terminal in this state, the setting reception unit 108 presents a screen for prompting the user for initial setting to the terminal. The setting reception unit 108 performs initial setting based on the setting message input by the user via the screen. FIG. 3 shows an example of a screen for initial setting. FIG. 4 shows an example of setting each setting item on the initial setting screen.

When the initial setting is completed, the setting verification unit 106 confirms whether or not the controller unit 103 normally operates with the connected device (step 204). For example, if a control command is sent from the controller unit 103 to a device on a trial basis and a response is not returned to the sent control command, or if the returned data cannot be decoded normally (data of a broken byte string is (When returned) etc., it is determined that the controller unit 103 is not operating normally. If the controller unit 103 is not operating normally, it is determined that the setting of the controller unit 103 needs to be changed, that is, the controller currently used in the controller unit 103 needs to be changed to another controller (step 205). Then, the setting acceptance unit 108 is validated (step 203). When there is access from the terminal in this state, the setting reception unit 106 presents a screen for prompting the user to set the controller unit 103 to the terminal. The setting reception unit 108 changes the setting of the controller unit 103 based on the setting message input by the user. FIG. 5 shows an example of a screen for setting the controller section. The user can change the setting of the controller unit 103 (change the controller to be used) by clicking the change button. When there are a plurality of candidates for the controller to be changed, the plurality of candidates may be displayed so that the user can select the candidate. In the example of the figure, there is one candidate for the controller to be changed, and information on the candidate is displayed.

When the controller unit 103 is operating normally, the setting verification unit 106 confirms whether or not 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 trial basis and confirms whether the control according to the instructed operation is 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 has occurred, it is determined that the protocol to be used needs to be changed (step 207) and the setting reception unit 108 is enabled. (Step 203). When the terminal accesses the communication adapter in this state, the setting reception unit 108 presents a screen for prompting the user to set the protocol control unit (change protocol) to the terminal, and the setting message input by the user is displayed. Set the protocol based on. FIG. 6 shows an example of the screen for setting the protocol control unit. The user can click the change button to change the protocol. When there are a plurality of protocol candidates to be changed, the plurality of candidates may be displayed so that the user can select the candidates. In the example of the figure, there is one candidate for 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. It is confirmed whether they match (step 209).
If they do not match, it is determined that the connection destination device may have been replaced (step 210). Then, the setting accepting unit 108 is enabled in order to notify the user of that fact or to review the setting (step 203). When the terminal accesses the communication adapter in this state, the setting reception unit 108 displays a screen including the device information detected through the protocol control unit 105 and the device information registered in the storage unit 110, that is, the connection. Present the user with a screen notifying the user that the previous device may have been changed. An example of the presented screen is shown in FIG. Based on the screen, the user confirms whether or not there is any problem with the current registered contents of the storage unit 110, and if there is no problem, selects (clicks) the approval button. By urging the user to approve, it is possible to prevent the device from being controlled without noticing the change in the model/device. Even if the acquired device information (model information, device ID, etc.) is different from the one registered in the storage unit 110, if the protocol control unit 105 and the controller unit 103 are normal, some functions (power supply) The device can be controlled normally (for example, on and off).

On the other hand, when the device information detected through the protocol control unit 105 matches the one registered in the storage unit 110, it is determined that the communication adapter setting is normal (step 210), and the control reception unit 107 is enabled. (Step 211). When there is access from the terminal to the communication adapter in this state, the control reception unit 107 presents a device control screen for operating or controlling the device to the terminal. 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 sends 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.

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

For example, when only notifying the user that the settings are incorrect, it is difficult to determine which part of the controller unit, the protocol control unit, etc. is erroneously set. In this embodiment, the setting of the controller unit is verified, and if it is incorrect, the fact is notified, so that the user can correctly understand that the setting of the controller unit is incorrect. 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 fact is notified, so that the user can correctly understand 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 allowed to select another controller, but the correct controller is automatically estimated from the content of the error. A method is also possible. For example, an identification model for estimating the controller from the error data (broken information) is prepared, the setting verification unit 106 estimates the correct controller from the identification model and the error data, and the setting acceptance unit 108 is used. You may propose to the user. Alternatively, the setting corrector 106 may automatically set the estimated correct controller setting in the controller 103. The model may be constructed by machine learning. That is, a method of preparing a large number of set data of error data and a correct controller and constructing a model by machine learning using these as teacher data is well known. Here, the correct controller is estimated, but the same protocol may be used to estimate the correct protocol. The estimation using the model may be performed not in the communication adapter but in 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 the correct controller setting information 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 allowed to select another candidate for the protocol. You may be able to narrow down the candidates. For example, some protocol specifications may specify even physical layer (=controller) specifications. If the current controller unit 103 settings do not match those of a particular protocol specification, that particular protocol can in principle be removed from the candidates. Therefore, a protocol other than the specific protocol may be presented to the user as a candidate. For example, in a certain home appliance protocol (probably home appliance protocol A), when the PHY-based specification is specified as the physical layer specification, the correspondence relation of "UART -> home appliance protocol A" is defined as the controller protocol correspondence table. Set to. When 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. Instead of presenting the identified candidate to the user, the setting verification unit 106 may automatically apply the setting of the candidate to the protocol control unit. When there are a plurality of candidates, one of the settings may be applied, and if the applied setting is incorrect, another candidate may be selected again and the selected candidate may be applied.
