Hereinafter, a development environment construction system according to an embodiment will be described using drawings.

FIG. 1 is a configuration diagram showing an example of a cloud environment 100 and a local environment 200 including a development environment construction system (construction processing server 10) according to an embodiment. For example, the cloud environment 100 and the local environment 200 are communicably connected via the Internet or the like.

The construction processing server 10 is an example of a development environment construction system that constructs a development environment for software that controls a target device configured with hardware. The development environment constructed by the construction processing server 10 includes virtual devices configured virtually. In FIG. 1, a real device A300 is shown as the target device. The real device A300 is a device (physical device) configured with hardware, and is, for example, a device mounted on a vehicle. Devices installed in a vehicle include an ECU (Electronic Control Unit) controlled by an in-vehicle device via a CAN (Controller Area Network) or Ethernet (registered trademark), or a touch panel for IVI (In Vehicle Infotainment). There are screen displays, etc.

For example, the real device A300 is placed in the local environment 200 where the user 400 verifies the real device A300 and the like. For example, local environment 200 is provided with clients 210 and 220. The clients 210 and 220 are computers such as PCs (Personal Computers) installed in the local environment 200.

For example, it is assumed that a development environment for a plurality of virtually configured virtual devices has already been constructed in the cloud environment 100 by emulating a plurality of physical devices including the real device A 300 as software. In contrast, there is a desire to use a development environment in which a specific device among a plurality of virtual devices is a physical device. The construction processing server 10 is intended to meet such demands, and is capable of constructing a development environment in which physical devices and virtual devices coexist.

For example, the construction processing server 10 is provided in a cloud environment 100. However, the construction processing server 10 does not need to be provided in the cloud environment 100, and may be provided in an environment that can communicate with the cloud environment 100 and the local environment 200.

The construction processing server 10 includes an acquisition section 11 , a determination section 12 , a construction section 13 , a trial section 14 , and a presentation section 15 . The construction processing server 10 is a computer including a processor, memory, and the like. The memory includes ROM (Read Only Memory), RAM (Random Access Memory), and the like, and can store programs executed by a processor. The acquisition section 11, the determination section 12, the construction section 13, the trial section 14, and the presentation section 15 are realized by a processor that executes a program stored in a memory, or the like. Note that the acquisition unit 11, the determination unit 12, the construction unit 13, the trial unit 14, and the presentation unit 15 may be arranged in one server (one housing) or in multiple servers (multiple housings). They may be distributed and arranged.

The acquisition unit 11 acquires development environment specification information, virtual device information, and construction capability information. The operation of the acquisition unit 11 and details of each piece of information will be described later.

The determining unit 12 determines where the development environment will be constructed. Details of the operation of the determining unit 12 will be described later.

The construction unit 13 constructs a development environment at the determined construction destination. Details of the operation of the construction unit 13 will be described later.

The trial unit 14 tests whether software for controlling the target device can be developed in the established development environment. Details of the operation of the trial section 14 will be described later.

The presentation unit 15 presents the results of the trial by the trial unit 14. Details of the operation of the presentation unit 15 will be described later.

The cloud environment 100 stores a plurality of virtual device information regarding a plurality of virtual devices included in a development environment built in the cloud environment 100. The virtual device information includes parameters required when using a virtual device, and the parameters are managed in a table or the like. Here, as an example of multiple pieces of virtual device information, virtual device A information 30a regarding virtual device A that is virtually configured by emulating real device A 300 as software, and virtual device A information 30a regarding virtual device A that is configured virtually by emulating real device A 300 as software, and real device B (not shown) as software. Virtual device B information 30b regarding virtual device B that is virtually configured through emulation is shown.

The virtual device A information 30a includes device control software specification information 31, virtual IF setting information 32, virtual device software specification information 33, response performance request information 34, and virtual device setting information 35 regarding the virtual device A. Here, the explanation will focus on the virtual device A for the real device A300, but this information exists for each real device. In other words, the cloud environment 100 may store virtual device information corresponding to various other real devices.

The device control software specification information 31 is information indicating the content or acquisition source of software (device control software) that controls the virtual device A included in the development environment built in the cloud environment 100. For example, the device control software specification information 31 includes git repository access information or information indicating which code state in the repository. By using the device control software specification information 31, software for controlling the virtual device A can be used.

The virtual IF setting information 32 is setting information regarding settings of a virtual interface that is an input/output interface for virtual device A when controlling virtual device A from the software (device control software). For example, the virtual IF setting information 32 includes access destination information for virtual device A. Note that by changing the virtual IF setting information 32, the access destination can be changed to the real device A300, and the real device A300 can be controlled from the device control software.

The virtual device software specification information 33 is information indicating the content or acquisition source of the software indicating the virtual device A. For example, the virtual device software specification information 33 includes git repository access information or information indicating which code state in the repository. By using the virtual device software specification information 33, the virtual device A can be used.

The response performance request information 34 is information indicating the responsiveness required when controlling the virtual device A. For example, the response performance request information 34 includes the response time required when controlling the virtual device A, and the like.

The virtual device setting information 35 includes resource information indicating computational resources required when controlling the virtual device A. For example, the resource information includes calculation resources such as the number of CPU cores and the amount of memory required when the virtual device A is implemented using an HV or the like.

The virtual device B information 30b also includes the same information regarding the virtual device B as the virtual device A information 30a. For example, in the above description, by replacing virtual device A with virtual device B, the virtual device B information 30b will be explained. The same applies to other virtual device information.

For example, the user 400 may transmit the development environment specification information 20 indicating the specifications of a development environment in which physical devices and virtual devices coexist to a device (PC or mobile terminal) that is communicably connected to the cloud environment 100 or the local environment 200. etc.). Alternatively, the development environment specification information 20 may be stored in a device in the cloud environment 100 or the local environment 200. For example, the development environment specification information 20 includes information indicating which physical device is specified (here, information indicating that real device A is specified) and information indicating the location of real device A 300. The information indicating the location of the real device A300 includes, for example, the location where the real device A300 exists (here, the local environment 200), the connected device (here, the client 210), and the like.

In addition, construction capability information indicating the development environment construction capability is stored in devices that are candidates for construction destinations of the development environment. For example, the client 210 stores construction capability information 40a, the client 220 stores construction capability information 40b, and the cloud environment 100 stores construction capability information 40c.

For example, the construction capability information 40a includes information indicating whether or not a development environment can be constructed in the client 210, or information indicating the storage capacity of the storage that the client 210 has. The information indicating whether or not the development environment can be constructed may be information indicating whether the client 210 includes an HV. If the client 210 does not include an HV, it is not possible to construct the development environment on the client 210. It's okay. Further, the information indicating whether or not the development environment can be constructed may be information indicating whether the client 210 is permitted to construct the development environment, and if the client 210 is not permitted to construct the development environment, It may not be possible to construct a development environment on the client 210. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage that the client 210 has.

For example, the construction capability information 40b includes information indicating whether or not a development environment can be constructed in the client 220, or information indicating the storage capacity of the storage that the client 220 has. The information indicating whether or not it is possible to construct a development environment may be information indicating whether or not the client 220 includes an HV, and if the client 220 does not include an HV, it is not possible to construct a development environment on the client 220. It's okay. Further, the information indicating whether or not the development environment can be constructed may be information indicating whether the client 220 is permitted to construct the development environment, and if the client 220 is not permitted to construct the development environment, It may be impossible to construct a development environment on the client 220. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage that the client 220 has.

For example, the construction capability information 40c includes information indicating whether or not a development environment can be constructed in the cloud environment 100, or information indicating the storage capacity of the storage that the cloud environment 100 has. The information indicating whether or not it is possible to construct a development environment may be information indicating whether the cloud environment 100 is permitted to construct a development environment, and if the cloud environment 100 is not permitted to construct a development environment, It may not be possible to construct a development environment in the cloud environment 100. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage that the cloud environment 100 has.

Next, details of the operation of the construction processing server 10 will be explained using FIG. 2.

FIG. 2 is a flowchart showing an example of the operation of the development environment construction system (construction processing server 10) according to the embodiment.

First, the acquisition unit 11 obtains development environment specification information 20 indicating specifications of the development environment, virtual device information regarding virtual devices (for example, virtual device A information 30a and virtual device B information 30b, etc.), and candidates for construction destinations of the development environment. The construction capability information (for example, construction capability information 40a to 40c, etc.) indicating the construction capability of the development environment is acquired (step S11). The acquisition unit 11 acquires this information from the cloud environment 100 or the local environment 200, but the acquisition destination of this information is not limited to the cloud environment 100 or the local environment 200. For example, these pieces of information may not be stored in the cloud environment 100 or the local environment 200, and the acquisition unit 11 may acquire these pieces of information from an environment other than the cloud environment 100 or the local environment 200.

Next, the determining unit 12 determines where to build the development environment based on the development environment specification information 20, virtual device information, and construction capability information (step S12). For example, the determining unit 12 may determine either the cloud environment 100 or the local environment 200 as the construction destination of the development environment, and further determines the specific You may decide on the equipment.

For example, the determining unit 12 may determine the construction destination based on conditions regarding the development environment specification information 20, virtual device information, and construction capability information. For example, the determining unit 12 determines, as the conditions regarding the development environment specification information 20, the conditions of the location of the target device, the responsiveness and computational resources required to control each virtual device (virtual devices A, B, . . . ). The construction destination may be determined based on the conditions of the development environment construction destination candidate, the conditions of whether or not the development environment can be constructed in the development environment construction destination candidate, the storage capacity conditions of the development environment construction destination candidate, and the like.

Specifically, regarding the location condition of the target device, a device to which the target device is connected or a device in a LAN (Local Area Network) to which the device is connected is likely to be determined as the construction destination. Regarding the responsiveness conditions required when controlling each virtual device (virtual devices A, B, . . . ), it becomes easier to determine a device to be constructed that has the performance to realize the responsiveness. With respect to the computational resource conditions required when controlling each virtual device, a device having performance (such as the number of CPU cores and remaining storage capacity) that satisfies the computational resources is likely to be determined as the construction destination. Regarding the conditions for determining whether or not a development environment can be constructed among candidates for a development environment construction destination, devices that are capable of constructing a development environment are more likely to be determined as the construction destination. Regarding the storage capacity conditions for candidates for the construction destination of the development environment, it is easier to determine the device having the required storage capacity as the construction destination.

Note that the user 400 may specify the construction destination of the development environment, and the determining unit 12 may decide the construction destination of the development environment to be the construction destination specified by the user 400.

Furthermore, the construction processing server 10 may include an output unit (not shown) that outputs information indicating the determined construction destination. Thereby, the user 400 can confirm the determined construction destination.

Next, the construction unit 13 constructs a development environment at the determined construction destination by changing the virtual IF setting information 32 (step S13). For example, the virtual IF setting information 32 is changed from a virtual interface setting for a virtual device (for example, virtual device A) to a virtual interface setting for a target device (for example, real device A 300). This allows the software that controls the virtual device to control the target device. By changing the virtual IF setting information 32, when the development environment is built at the determined construction destination, the target device can be controlled, so development will automatically start at the determined construction destination. You can build an environment. In other words, when constructing the development environment at the determined construction destination, there is no need to manually change the virtual IF setting information 32.

The trial unit 14 then tests whether software for controlling the target device can be developed in the created development environment (step S14), and the presentation unit 15 presents the result of the trial (step S15). For example, as a result of the trial, the presenting unit 15 presents whether development is possible or not, in other words, whether or not the development environment has been successfully constructed, and if it is successful, it also presents the construction destination. good. For example, if the process fails, the processes from step S12 to step S15 may be repeated until the process succeeds.

Note that if a plurality of construction destinations are determined in step S12, the user 400 may select which construction destination is to construct the development environment.

Further, priorities may be determined for candidates for development environment construction destinations, and in steps S12 to S15, construction destinations are determined in descending order of priority, and the results of development environment construction, trials, and trials are determined. may be presented. For example, if the construction of a development environment fails in a construction destination with a high priority, the next highest priority construction destination is determined, and even if the development environment is constructed, a trial is performed, and the results of the trial are presented. good.

Here, examples of information included in the development environment specification information 20, virtual device information, and construction capability information, and the construction An example of the operation of the processing server 10 will be described.

First, a case where the client 210 is presented as a development environment construction destination will be described.

For example, the development environment specification information 20 includes the global IP address of the local environment 200 as information on the location where the real device A 300 exists, and the local IP address of the client 210 as information on the client linked to the local environment 200. and the local IP address of client 220. Note that the development environment specification information 20 includes information similar to the local environment 200 regarding a local environment (not shown).

For example, the development environment specification information 20 includes information regarding the physical device (real device), including information indicating the type of the actual device A 300 (for example, storage) and information indicating the connected client (for example, the client 210). Contains combinations.

For example, the virtual device A information 30a includes information indicating the type of device (for example, storage), virtual device setting information 35 (for example, required storage capacity is 10 GB or more), and response performance request information 34 (for example, within 100 ms). Includes combinations.

For example, the construction capability information 40a includes information indicating that the client 210 is capable of constructing a development environment (information indicating that there is an HV), and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40b includes information indicating that the client 220 is unable to construct a development environment (information indicating that there is no HV), and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40c includes information indicating that the Clyde environment 100 is capable of constructing a development environment (information indicating that there is an HV), and information indicating that the remaining storage capacity is 1 TB. .

When the above information is included in the development environment specification information 20, virtual device information, and construction capability information, the construction processing server 10 operates as follows.

The determining unit 12 checks the virtual device A information 30a corresponding to the real device A300 based on the information indicating the type of the real device A300 specified in the information regarding the physical device (real device), and determines that the required storage capacity is 10 GB. This is the above, and it is confirmed that the required response is within 100ms. The determining unit 12 determines that the client 220 is inappropriate as a construction destination based on the construction capability information 40b. The determining unit 12 determines that the remaining storage capacity of both the client 210 and the cloud environment 100 is sufficient based on the construction capacity information 40a and 40c.

The construction unit 13 constructs a development environment for the client 210 and the cloud environment 100 based on information on the locations where the client 210 and the cloud environment 100 are located. For example, the construction unit 13 may access the IP address and issue construction instructions, or the software that communicates with the cloud and acquires data may be located at each location where the client 210 and the cloud environment 100 exist. good.

The trial unit 14 tests whether software can be developed in the development environments built for the client 210 and the cloud environment 100, respectively. Specifically, the trial unit 14 operates the development environment on each of the client 210 and the cloud environment 100, and checks whether the requirements indicated by the virtual device setting information 35 and the response performance request information 34 are satisfied. For example, assume that the responsiveness of the cloud environment 100 exceeds 100 ms. As a result, the cloud environment 100 is determined to be inappropriate as a construction site for a development environment, and the presentation unit 15 presents the client 210 as a result of the trial.

Next, a case where the cloud environment 100 is presented as a construction destination for the development environment will be described.

For example, the development environment specification information 20 includes the global IP address of the local environment 200 as information on the location where the real device A 300 exists, and the local IP address of the client 210 as information on the client linked to the local environment 200. and the local IP address of client 220. Note that the development environment specification information 20 includes information similar to the local environment 200 regarding a local environment (not shown).

For example, the development environment specification information 20 includes information regarding the physical device (real device), including information indicating the type of the actual device A 300 (for example, display) and information indicating the connected client (for example, client 210). Contains combinations.

For example, the virtual device A information 30a includes information indicating the type of device (for example, display), virtual device setting information 35 (for example, the number of allocated CPU cores is 4 or more), and response performance request information 34 (for example, within 1 s). Includes a combination of

For example, the construction capability information 40a includes information indicating that the client 210 is capable of constructing a development environment (information indicating that there is an HV), and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40b includes information indicating that the client 220 is unable to construct a development environment (information indicating that there is no HV), and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40c includes information indicating that the Clyde environment 100 is capable of constructing a development environment (information indicating that there is an HV), and information indicating that the remaining storage capacity is 1 TB. .

When the above information is included in the development environment specification information 20, virtual device information, and construction capability information, the construction processing server 10 operates as follows.

The determining unit 12 checks the virtual device A information 30a corresponding to the real device A300 based on the information indicating the type of the real device A300 specified in the information regarding the physical device (real device), and determines that the number of allocated CPU cores is 4. This is the above, and it is confirmed that the required response is within 1 s. The determining unit 12 determines that the client 220 is inappropriate as a construction destination based on the construction capability information 40b.

The construction unit 13 constructs a development environment for the client 210 and the cloud environment 100 based on information on the locations where the client 210 and the cloud environment 100 are located. For example, the construction unit 13 may access the IP address and issue construction instructions, or the software that communicates with the cloud and acquires data may be located at each location where the client 210 and the cloud environment 100 exist. good.

The trial unit 14 tests whether software can be developed in the development environments built for the client 210 and the cloud environment 100, respectively. Specifically, the trial unit 14 operates the development environment on each of the client 210 and the cloud environment 100, and checks whether the requirements indicated by the virtual device setting information 35 and the response performance request information 34 are satisfied. For example, assume that the client 210 is able to allocate only two CPU cores. As a result, the client 210 is determined to be inappropriate as a destination for building a development environment, and the presentation unit 15 presents the cloud environment 100 as a result of the trial.

Next, a case where the development environment is built in the local environment 200 will be explained using FIG. 3, and a case where the development environment is built in the cloud environment 100 will be explained using FIG. 4.

FIG. 3 is a configuration diagram showing an example of a development environment 500 built in the local environment 200. For example, assume that a development environment 500 is built on the client 210 in the local environment 200. FIG. 3 shows a development environment 510 for device A and a development environment 520 for device B.

The development environment 510 includes device A control software 511, virtual IF setting information 512 for real device A, virtual device A 513, and virtual device setting information 515.

The device A control software 511 is software indicated by the device control software designation information 31 included in the virtual device A information 30a shown in FIG. 1, and is software for controlling the real device A300. However, since the device A control software 511 is software developed for the virtual device A513, the user 400, for example, uses the development environment 500 to improve the device A control software 511 according to the real device A300. go.

The virtual IF setting information 512 for real device A is the virtual IF setting information 32 included in the virtual device A information 30a shown in FIG. 1, which has been changed to the virtual interface setting for the real device A300. The virtual IF setting information 512 for the real device A is a virtual interface setting for the real device A300, so that the real device A300 can be controlled by the device A control software 511.

The virtual device A 513 is a virtual device indicated by the virtual device software specification information 33 included in the virtual device A information 30a shown in FIG. Since the development environment 510 is a development environment for software that controls the real device A300, the virtual device A513 does not need to be used. Alternatively, the virtual device A 513 may also be used in the development environment 510 depending on the situation.

The virtual device setting information 515 is the virtual device setting information 35 included in the virtual device A information 30a shown in FIG.

The development environment 520 includes device B control software 521, virtual IF setting information 522 for virtual device B, virtual device B 523, and virtual device setting information 525.

The device B control software 521 is software indicated by the device control software designation information 31 included in the virtual device B information 30b shown in FIG. 1, and is software for controlling the virtual device B 523.

The virtual IF setting information 522 for virtual device B is the virtual IF setting information 32 included in the virtual device B information 30b shown in FIG. 1, which is the virtual interface setting for the virtual device B 523. Since the virtual IF setting information 522 for virtual device B is a virtual interface setting for virtual device B 523, virtual device B 523 can be controlled by device B control software 521.

The virtual device B 523 is a virtual device indicated by the virtual device software specification information 33 included in the virtual device B information 30b shown in FIG. Since the development environment 520 is a development environment for software that controls the virtual device B523, the virtual device B523 is used. In this way, the development environment 500 includes a development environment 510 related to the real device A 300 and a development environment 520 related to the virtual device B 523.

The virtual device setting information 525 is the virtual device setting information 35 included in the virtual device B information 30b shown in FIG. For example, client 210 includes an HV, and this HV determines the number of CPU cores to be allocated to development environment 520 according to virtual device setting information 525. However, it may be discovered after the development environment 500 is constructed that the CPU performance is low with this allocated number of CPU cores. In such a case, the virtual device setting information 525 may be changed so that the CPU performance is sufficient, that is, the number of CPU cores allocated in the virtual device setting information 525 may be increased. For example, when building the next development environment (for example, it may be when building the development environment for real device A, or when building the development environment for other real devices), the virtual device settings The changes to the information 525 (virtual device setting information 35) may be presented to the user 400 or the like and applied.

FIG. 4 is a configuration diagram showing an example of a development environment 600 built in the cloud environment 100. FIG. 4 shows a development environment 610 for device A and a development environment 620 for device B.

The development environment 610 includes device A control software 611, virtual IF setting information 612 for real device A, virtual device A 613, and virtual device setting information 615.

The device A control software 611 is software indicated by the device control software designation information 31 included in the virtual device A information 30a shown in FIG. 1, and is software for controlling the real device A300.

The virtual IF setting information 622 for virtual device B is the virtual IF setting information 32 included in the virtual device B information 30b shown in FIG. 1, which is the setting of a virtual interface for virtual device B 623. Since the virtual IF setting information 622 for virtual device B is a virtual interface setting for virtual device B 623, virtual device B 623 can be controlled by device B control software 621.

The virtual device B 623 is a virtual device indicated by the virtual device software specification information 33 included in the virtual device B information 30b shown in FIG. Since the development environment 620 is a development environment for software that controls the virtual device B623, the virtual device B623 is used. In this way, the development environment 600 includes a development environment 610 related to the real device A 300 and a development environment 620 related to the virtual device B 623.

The virtual device setting information 625 is the virtual device setting information 35 included in the virtual device B information 30b shown in FIG. For example, cloud environment 100 includes an HV, and this HV determines the number of CPU cores to be allocated to development environment 620 according to virtual device setting information 625. However, it may be discovered after the development environment 600 is constructed that the CPU performance is low with this allocated number of CPU cores. In such a case, the virtual device setting information 625 may be changed so that the CPU performance is sufficient, that is, the number of CPU cores allocated in the virtual device setting information 625 may be increased. For example, when building the next development environment (for example, it may be when building the development environment for real device A, or when building the development environment for other real devices), the virtual device settings The changes to the information 625 (virtual device setting information 35) may be presented to the user 400 or the like and applied.
