Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiments. In the drawings described below, components having the same function are denoted by the same reference numerals, and repeated description thereof may be omitted.

(First embodiment)
FIG. 1 is a schematic diagram of a setting method of the relay device 10 according to the present embodiment. The relay device 10 is also referred to as a gateway, and is a communication device that relays signal transfer between the device 20 and the server 30. The server 30 is a device connected to the relay apparatus 10 via a network. The server 30 is, for example, a single computer or a cloud that is a collection of computer resources.

The device 20 is a device that transmits a predetermined signal to the server 30 or receives a signal from the server 30 to perform a predetermined operation. For example, the device 20 is a sensor that measures temperature, pressure, sound, and the like. In this case, the device 20 transmits a signal indicating the measurement result to the server 30. For example, the device 20 is an actuator that performs a predetermined operation. In this case, the device 20 operates according to a signal indicating the control content received from the server 30. The device 20 is controlled by the application 11 operating on the relay apparatus 10.

The relay apparatus 10 is provided with one or more connection ports 12 that are physical connection units, and the device 20 can be connected to the connection port 12. The connection port 12 is an interface for physically connecting the device 20 via a connection member such as a cable or a connector. As the connection port 12, for example, a serial port (COM port) such as RS-232C standard, RS-422 standard, RS-485 standard, an IEEE 1284 standard parallel port, a USB (Universal Serial Bus) port, or any other physical interface is used. It's okay.

The application 11 is software that controls the device 20 and enables communication with the server 30. Communication between the relay apparatus 10 and the server 30 follows a general protocol such as TCP / IP. On the other hand, the device 20 performs communication according to a different communication protocol for each type and manufacturer. As a communication protocol that the device 20 follows, for example, there is a general protocol such as TCP / IP, or a unique protocol that varies depending on the type and manufacturer of the device 20. The application 11 converts a signal transmitted and received between the device 20 and the server 30 according to a communication protocol that the device 20 and the server 30 follow. Therefore, the relay apparatus 10 needs to install and execute an application 11 that differs depending on the device 20 to be connected.

The control unit 100 installs the application 11 corresponding to the device 20 connected to the relay device 10 and performs control to be executed in the relay device 10. In the control, the control unit 100 determines the application 11 to be installed based on the combination of the identification information of the connected device 20 and the identification information of the relay device 10. The data of the application 11 installed in the present embodiment is received from the server 30, but may be read from a recording unit in the relay device 10. A detailed configuration of the control unit 100 will be described with reference to FIG.

FIG. 2 is a block diagram of a system including the relay device 10 according to the present embodiment. In FIG. 2, arrows indicate main data flows, and there may be data flows other than those shown in FIG. In FIG. 2, each block represents a functional unit configuration, not a hardware (device) unit configuration. Therefore, the blocks shown in FIG. 2 may be implemented in a single device, or may be separately implemented in a plurality of devices. Data exchange between the blocks may be performed via any means such as a data bus, a network, a portable storage medium, or the like.

The relay apparatus 10 includes a control unit 100 that is a processing unit and a system information storage unit 13 that is a storage unit. The control unit 100 includes a device identification information acquisition unit 110, a relay device identification information acquisition unit 120, an application determination unit 130, and an installation unit 140. In addition, the relay device 10 executes an application 11 that controls communication between the device 20 and the server 30. The server 30 includes an application definition storage unit 31 and an application storage unit 32 that are storage units.

The device identification information acquisition unit 110 acquires from the device 20 a device ID that is identification information of the device 20 connected to the relay apparatus 10. When a plurality of devices 20 are connected to the relay apparatus 10, the subsequent processing is performed for each device 20. The device ID is a value that can be acquired from the device 20, and is defined by an arbitrary expression method such as a character string, a numerical value, or a binary value that can identify the device 20. When the device 20 is a USB connection device, for example, a vendor (manufacturer) ID, a product ID, or a combination thereof can be used as the device ID.

In the present embodiment, the same identification information is allocated to a plurality of devices 20 (for example, devices 20 of the same type and manufacturer) that follow the same communication protocol. With such a configuration, a plurality of devices 20 having the same identification information are controlled by the same application 11, and thus management in an application definition table described later is simple. As another method, unique identification information may be assigned to each individual device 20.

The relay device identification information acquisition unit 120 acquires the relay device ID that is the identification information of the relay device 10 from the system information storage unit 13. The relay device ID is a value that can be acquired from the system (more specifically, the operating system) of the relay device 10 and is defined by an arbitrary expression method such as a character string, a numerical value, or a binary value that can identify the relay device 10. The As the relay device ID, for example, a serial number recorded in the BIOS of the relay device 10 can be used.

In this embodiment, unique identification information is assigned to each individual relay device 10. With such a configuration, different settings can be applied to each individual relay device 10, and the settings of the relay device 10 can be customized according to the user's request. In other words, even when the same type of device 20 is connected to the same type of relay device 10, different applications 11 can be distributed depending on the installation destination and owner of the relay device 10. It can be performed. As another method, the same identification information may be allocated to a plurality of relay apparatuses 10.

The application determination unit 130 is based on an application definition table recorded in advance in the application definition storage unit 31. The device ID acquired by the device identification information acquisition unit 110 and the relay device acquired by the relay device identification information acquisition unit 120. The application 11 corresponding to the ID is determined. In this embodiment, the application definition storage unit 31 is provided in the server 30, but may be provided in the relay device 10. However, when the application definition storage unit 31 is provided in the relay device 10, it is necessary to periodically distribute the application definition table from the server 30 to each relay device 10. It is desirable to provide a definition storage unit 31.

FIG. 3 is a schematic diagram of an application definition table recorded in advance in the application definition storage unit 31 according to this exemplary embodiment. The application definition storage unit 31 associates a combination of the device ID that is the identification information of the device 20, the relay device ID that is the identification information of the relay device 10, and the application 11 to be installed (specifically, the file name). And recorded in advance as an application definition table. Specifically, the application determination unit 130 extracts a row corresponding to the device ID acquired by the device identification information acquisition unit 110 and the relay device ID acquired by the relay device identification information acquisition unit 120 from the application definition table. . Then, the application determination unit 130 determines the application 11 (file name) included in the extracted line as the application 11 to be installed in the relay device 10.

3, the file name of the application 11 is recorded, but other identification information (ID, application name, etc.) that can identify the application 11 to be installed may be recorded.

In FIG. 3, the application definition table is represented as a character string table for visibility, but may be represented in an arbitrary data format (file format), for example, binary data or text data. The application definition table may be recorded in the application definition storage unit 31 as a database table, or may be recorded in the application definition storage unit 31 as a binary file or a text file.

The installation unit 140 is an installer that reads the application 11 determined by the application determination unit 130 from the application storage unit 32 and installs it in the relay apparatus 10. The installation of the application 11 is to introduce the application 11 into the relay device 10 and make it executable. That is, the installation of the application 11 includes placing an execution file of the application 11 in the relay device 10 and setting the system for the relay device 10 to execute the application 11. In the present embodiment, the application storage unit 32 is provided in the server 30, but may be provided in the relay device 10. However, when the application storage unit 32 is provided in the relay device 10, it is necessary to periodically distribute all the applications 11 from the server 30 to each relay device 10. It is desirable to provide the storage unit 32.

In the application storage unit 32, an execution file of the application 11 may be recorded, or a program (source code) of the application 11 may be recorded. When the execution file of the application 11 is recorded, the installation unit 140 copies the execution file read from the application storage unit 32 to the relay device 10 to install it in the relay device 10. When the program of the application 11 is recorded, the installation unit 140 installs the program read from the application storage unit 32 in the relay device 10 by compiling and making the program executable.

When a plurality of devices 20 are connected to the relay apparatus 10, the subsequent processing is performed for each device 20. Here, the device 20 that is determining the application 11 to be installed is referred to as a target device 20, and the device 20 in which the application 11 is already installed in the relay apparatus 10 is referred to as an existing device 20.

When the first target device 20 is connected to the relay apparatus 10, that is, when there is no existing device 20 connected to the relay apparatus 10 (YES in step S303), as in step S103 of FIG. In the application definition table recorded in advance in the application definition storage unit 31, the application determination unit 130 corresponds to the application 11 corresponding to the device ID (first device ID) of the target device 20 and the relay device ID acquired in step S302. Is determined as the application 11 to be installed in the relay device 10 (step S304).

When the second and subsequent devices 20 are connected to the relay device 10, that is, when there is an existing device 20 connected to the relay device 10 (NO in step S303), the device ID of the target device 20 and the existing device 20 It is determined whether or not the device ID of the device 20 is the same. When the target device 20 having a device ID different from that of the existing device 20 is connected (YES in step S305), the application determination unit 130 uses the application definition table recorded in the application definition storage unit 31 in advance. The application 11 corresponding to the device ID of the target device 20 (first device ID), the device ID of the existing device 20 (second device ID), and the relay device ID acquired in step S302 is installed in the relay device 10. It is determined as a power application 11 (step S306).

When the target device 20 having the same device ID as that of the existing device 20 is connected (NO in step S305), the process is terminated without installing the application 11.

Finally, the installation unit 140 reads the application 11 determined in step S304 or S306 from the application storage unit 32 and installs it in the relay device 10 (step S307).

The CPU 10a of the relay device 10 becomes the main body of each step (process) included in the setting method shown in FIG. That is, the CPU 10a reads the program for executing the setting method shown in FIG. 11 from the memory 10b or the storage device 10c, executes the program, and controls each unit of the relay device 10 to control the setting method shown in FIG. Execute.

This embodiment has the same effects as those of the first embodiment, and can further install the application 11 corresponding to the combination of the plurality of devices 20 in the relay apparatus 10. Therefore, more complicated settings such as installation of the application 11 that controls a plurality of types of devices 20 can be performed. Further, when the devices 20 having the same identification information are connected, the application 11 is not newly installed, so resources such as communication capacity can be reduced.
