In this embodiment, maintenance work refers to the purpose of providing various types of support such as troubleshooting when some kind of trouble occurs in the information processing device such as a personal computer or tablet, which is the device to be maintained, or as necessary. This refers to the work of For example, maintenance work includes investigative work to investigate the symptoms, related conditions, past operations that led to the condition, logs, hardware status, software versions, etc.; This may include response work for providing answers such as countermeasures, and operation work for remotely operating the equipment to be maintained for the purpose of resolving a problem. In addition to the above-mentioned examples, the maintenance work may include various types of work that are necessary when providing various types of support, such as solving troubles that occur to users.

Furthermore, maintenance functions refer to various functions used when performing the above-mentioned maintenance work remotely. For example, the maintenance functions include various functions that need to be executed in order to perform maintenance work remotely, and various functions that are desirable when performing maintenance work remotely. As an example, the maintenance function includes a transmission function for transmitting a video signal to the maintenance server 400, an acceptance function for accepting an operation signal transmitted by the maintenance server 400 to remotely control a device to be maintained, and the like. Here, the video signal refers to, for example, a signal that an information processing device that is a maintenance target device outputs to a screen display device such as a display device. Further, the operation signal refers to, for example, a signal output from an operation input device such as a keyboard, a mouse, or a trackpad to an information processing device that is a maintenance target device. The video signal and the operation signal correspond to part of the maintenance information used when performing maintenance work remotely. Note that the maintenance functions may include functions other than those exemplified above. For example, the maintenance functions include a request function that sends a request for maintenance work to the maintenance server 400, an image processing function that performs predetermined processing on at least a portion of the transmitted video, and a The storage function may include a storage function for storing usable information, a routine processing execution function for carrying out routine processing, an authentication function, a function for switching maintenance target devices to be remotely controlled, and other arbitrary functions.

FIG. 1 shows an example of the overall configuration of the maintenance system 100. Referring to FIG. 1, the maintenance system 100 includes a connection destination device 200, a KVM switch 300, a maintenance server 400, and an operator device 500. As shown in FIG. 1, the connection destination device 200 and the KVM switch 300 are connected to be able to communicate with each other. Furthermore, the KVM switch 300 and the maintenance server 400 can be connected to each other via a network or the like so that they can communicate with each other. Furthermore, the maintenance server 400 and the operator device 500 can be connected to each other via a network or the like so that they can communicate with each other. Note that, as shown in FIG. 1, the maintenance system 100 can include a plurality of connection destination devices 200 and a plurality of operator devices 500. The maintenance system 100 may include multiple KVM switches 300 and multiple maintenance servers 400.

The connection destination device 200 is a device that is connected to the KVM switch 300 and sends and receives various signals such as video signals and operation signals to and from the KVM switch 300. At least a portion of the connected device 200 corresponds to a maintenance target device that is a target of maintenance work performed by remote control. As an example, the connection destination device 200 is an information processing device such as a personal computer or a tablet. The connection destination device 200 may include a screen display device such as a display device, an operation input device such as a keyboard or a mouse, and other arbitrary devices.

The KVM switch 300 is a switch device that transmits and receives various signals, such as video signals and operation signals, between itself and the connected destination device 200. In addition, the KVM switch 300 can connect to the maintenance server 400 when certain conditions are met, and can execute maintenance functions according to inputs to the switch set 310.

FIG. 2 shows an example of the configuration of the KVM switch 300. Referring to FIG. 2, for example, a KVM switch 300 includes a switch set 310, a controller 320, an HDMI socket 330, a USB socket 340, and a communication module 350. Further, the KVM switch 300 can include at least a portion of an image processing chip 360, a secondary battery 370, a storage area 380, and a machine learning chip 390. The KVM switch 300 may be configured such that various functions such as an image processing chip 360, a secondary battery 370, a storage area 380, and a machine learning chip 390 can be removed or attached as necessary.

Note that FIG. 2 shows an example of the configuration of the KVM switch 300, and the configuration of the KVM switch 300 is not limited to that illustrated in FIG. 2. For example, KVM switch 300 may have one or more HDMI sockets 330 and USB sockets 340. In addition, although HDMI and USB are shown as examples in FIG. 2, the KVM switch 300 has other wired interfaces such as DisplayPort and S terminal, and wireless I/Fs (interfaces) such as Bluetooth (registered trademark). You can leave it there. The KVM switch 300 may use a protocol that wraps TCP/IP communication (for example, RDP, RTSP, or RTMP).

The switch set 310 has a configuration for receiving an input to enable at least one of the maintenance functions used when performing maintenance work using a remote device. For example, the switch set 310 may be implemented by hardware, such as a plurality of push buttons. The switch set 310 is realized by displaying the switches virtually on any screen display part of the KVM switch 300 or the like, or by having a computing device such as a CPU (Central Processing Unit) read a program. It's okay.

FIG. 3 shows an example of the configuration of the switch set 310. Referring to FIG. 3, for example, the switch set 310 includes a video transmission switch 311, an operation acceptance switch 312, an image processing switch 313, a storage enablement switch 314, and the like. Further, the switch set 310 may include a lighting section 315 that lights up when a corresponding switch is input.

The video transmission switch 311 is a switch that accepts an input to transmit a video signal to the maintenance server 400, which is an external device that performs maintenance work. For example, the video transmission switch 311 receives input in response to the user pressing the video transmission switch 311. As an example, when the video transmission switch 311 receives an input, transmission of the video signal to the maintenance server 400 is started. In other words, the KVM switch 300 can be configured not to transmit the video signal to the maintenance server 400 until the video transmission switch 311 accepts the input.

The operation acceptance switch 312 is a switch that accepts an input from the maintenance server 400 indicating that an operation signal for remotely controlling the connected device 200 is accepted. For example, the operation acceptance switch 312 accepts input in response to the user pressing the operation acceptance switch 312. As an example, when the operation acceptance switch 312 accepts an input, acceptance of the operation signal transmitted by the maintenance server 400 is started. In other words, the KVM switch 300 can be configured not to accept the operation signal transmitted by the maintenance server 400 until the operation acceptance switch 312 accepts the input.

The image processing switch 313 is a switch that accepts an input to perform predetermined image processing on a predetermined area on the screen. For example, the image processing switch 313 receives input in response to the user pressing the image processing switch 313. As an example, image processing is started when the image processing switch 313 receives an input. Note that image processing refers to, for example, blurring processing or masking processing by superimposing rectangular or circular areas. Further, the predetermined area on which image processing is performed may be, for example, predetermined, or may be configured so that it can be specified in response to an operation by a user operating the connection destination device 200 or the like. The predetermined area may be the entire image displayed on a screen display device or the like, or may be a part of the image.

The storage enablement switch 314 is a switch that accepts an input to start storing data in the storage area 380 or starting to utilize data stored in the storage area 380. For example, the storage enablement switch 314 receives input in response to the user pressing the storage enablement switch 314. As an example, when the storage enablement switch 314 receives an input, storage of data in the storage area 380, utilization of data stored in the storage area 380, etc. are started. For example, the storage area 380 may be configured to be used as a temporary storage area for patch application, or an image may be saved in advance in a bootable format and data can be downloaded by remote control as needed. It may be configured to perform reference, hardware diagnosis, etc. In the storage area 380, for example, a live image of Linux (registered trademark) is stored in advance, and various hardware such as HDD (hard disk drive), SSD (solid state drive), CPU, memory, etc. It may also be configured to check the operating status of the hardware or diagnose the remaining lifespan. Note that the storage enablement switch 314 may be configured to perform only one of storing data in the storage area 380 and utilizing data stored in the storage area 380, depending on an input.

The lighting section 315 lights up while the corresponding switch is accepting input. For example, the lighting section 315-1 lights up while the video transmission switch 311 is accepting input. Note that the video transmission switch 311 and the like may be configured to detect cancellation of input in response to being pressed again while accepting input. In this case, in response to the cancellation of the input, the lighting section 315 may cancel the lighting state and turn off the light.

The above is an example of the configuration of the switch set 310. Note that at least some of the switches included in the switch set 310 may be configured to accept input after a session, which will be described later, is started between the KVM switch 300 and the maintenance server 400 (operator device 500). good. The switch set 310 may accept input regardless of whether a session is established. Further, FIG. 3 shows an example of the switch set 310, and the configuration of the switch set 310 is not limited to the case illustrated in FIG. 3. The switch set 310 may include switches other than those shown in FIG. 3 corresponding to each of the maintenance functions described above. For example, the switch set 310 includes a request switch that sends a request for maintenance work to the maintenance server 400, a routine processing switch that performs a predetermined or learned routine process, a changeover switch for a maintenance target device, and the like. It's okay. The switch set 310 may include switches for performing arbitrary maintenance functions in addition to those exemplified above. For example, the switch set 310 may include a switch corresponding to a transmitting/receiving function that collectively starts transmitting and receiving maintenance information such as transmitting a video signal and accepting an operation signal.

The controller 320 controls whether or not to receive various signals such as operation signals and video signals, and the destination of transmission. In other words, the controller 320 functions as an execution unit that executes maintenance functions according to inputs to the switch set 310. For example, the controller 320 may be realized by a calculation device such as a CPU executing a program stored in a storage device.

For example, if the video transmission switch 311 does not accept input, the controller 320 controls the destination of the video signal so that the video signal is transmitted and received between the connected devices 200. On the other hand, if the video transmission switch 311 accepts the input, the controller 320 transmits and receives the video signal between the connected devices 200 and controls the video signal transmission destination to start transmitting the video signal to the maintenance server 400. . In this way, the controller 320 can perform the maintenance function of starting the transmission of a video signal to the maintenance server 400 in response to the input to the video transmission switch 311. Further, for example, when the operation acceptance switch 312 receives an input, the controller 320 can accept an operation signal received from the maintenance server 400 and transmit the accepted operation signal to the connected device 200 or the like. . The controller 320 may be configured to discard the received operation signal without accepting it until the operation acceptance switch 312 accepts the input.

Similarly, the controller 320 can execute a corresponding maintenance function in response to an input to a switch other than those exemplified above. For example, when the image processing switch 313 receives an input, the controller 320 can instruct the image processing chip 360 to start image processing. Also, the controller 320 can be configured to transmit a request for remote maintenance work to the maintenance server 400 when the request switch receives an input. The controller 320 may be configured to establish a session (maintenance session) with the maintenance server 400 in response to the response from the maintenance server 400 to the request. Also, the controller 320 may be configured to perform a predetermined routine process when the routine process switch receives an input. Here, the routine process may be a process that is realized based on a predetermined rule, such as "input F6 to open the boot menu and execute the third menu from the top," or a process that uses image processing or machine learning, such as "input F6 to recognize the 'boot from USB' menu using image processing using machine learning, and output operation input information so that the cursor is positioned in the appropriate position." The rules for routine processing and the learning model that has been learned in advance to execute routine processing may be stored in advance in the storage area 380, for example, or may be configured to be downloaded one by one via the communication module 350, etc. The controller 320 may start executing a corresponding maintenance function in response to an input to another switch.

The HDMI socket 330 is used for receiving and transmitting video signals. For example, via an HDMI cable connected to the HDMI socket 330, a video signal is received from an information processing device or the like that is the connection destination device 200, or a video signal is transmitted to a screen display device or the like that is the connection destination device 200. You can send it. Note that the HDMI socket 330 may be a general type.

The USB socket 340 is used for receiving and transmitting operation signals. For example, an operation signal can be sent to or received from the information processing device, operation input device, or the like that is the connection destination device 200 via a USB cable connected to the USB socket 340. KVM switch 300 may receive power via USB socket 340 to operate KVM switch 300 . Note that the USB socket 340 may be a general type.

The communication module 350 is used to transmit and receive various signals to and from the maintenance server 400. The communication module 350 may be configured to perform network communication wirelessly or wired. The KVM switch 300 can transmit and receive video signals and operation signals to and from the maintenance server 400 via the communication module 350. The communication module 350 may be a general one.

The image processing chip 360 performs predetermined image processing on a predetermined area within the screen. The image processing chip 360 may be a GPU (Graphics Processing Units) or the like. For example, the image processing chip 360 can perform image processing in response to an instruction issued by the controller 320 in response to pressing the image processing switch 313. As described above, the image processing chip 360 may perform image processing such as blurring processing and masking processing by superimposing rectangular/circular areas. Further, the image processing chip 360 may perform image processing on a predetermined area, or may accept a designation of an area for image processing from a user operating the connected device 200 or the like.

The secondary battery 370 is an auxiliary power source that can be used in the event of a power outage. The secondary battery may be a common battery that provides power until it is safely shut down.

The storage area 380 is a storage device that allows data to be stored and pre-stored data to be utilized in accordance with input to the storage enablement switch 314. The storage area 380 may be configured to be used as a temporary storage area for patch application, or an image may be saved in advance in a bootable format, and the data may be stored by executing the image remotely as necessary. It may also be configured to refer to the information and diagnose the hardware. In other words, in the storage area 380, for example, a live image of Linux (registered trademark) is stored in advance, and the operating status of each hardware such as the HDD, SSD, CPU, and memory can be checked by remote control. , the remaining life may be diagnosed. Note that the storage enablement switch 314 may be configured to perform only one of storing data in the storage area 380 and utilizing data stored in the storage area 380, depending on an input.

The machine learning chip 390 can be used when learning a learning model used when performing the above-mentioned routine processing. The machine learning chip 390 may be a GPGPU (General-purpose computing on graphics processing units) or the like.

The above is an example of the configuration of the KVM switch 300.

The maintenance server 400 can be connected to the KVM switch 300, and can also be connected to the operator device 500, which is an information processing device for an operator who performs remote control. For example, the maintenance server 400 can transmit a video signal received from the KVM switch 300 to the operator device 500, or can transmit an operation signal received from the operator device 500 to the KVM switch 300.

For example, in response to a request from the KVM switch 300, the maintenance server 400 checks whether the operator device 500 can be assigned. If the operator device 500 replies that the assignment is possible, the maintenance server 400 responds to the request to the KVM switch 300 and starts a session with the KVM switch 300. The maintenance server 400 is also configured to be able to appropriately route signals received from the KVM switch 300 during an established session to the corresponding operator device 500. Routing may be achieved using known technology. The maintenance server 400 and the operator device 500 may be connected to each other via wired or wireless communication so that they can communicate with each other.

As described above, according to the KVM switch 300 described in this embodiment, the operator device 500 can receive a video signal from the maintenance target device via the KVM switch 300 and the maintenance server 400. Further, the operator device 500 can transmit operation signals to the maintenance target device via the KVM switch 300 and the maintenance server 400. As a result, according to the above configuration, the operator operating the operator device 500 can remotely operate the maintenance target device while checking the video output output by the maintenance target device.

The above is an example of the configuration of the maintenance system 100. Next, an example of the operation of the KVM switch 300 will be described with reference to FIGS. 4 and 5.

FIG. 4 is an example of the operation of the KVM switch 300 and the maintenance server 400 when establishing a session for performing maintenance work. Referring to FIG. 4, the KVM switch 300 receives a maintenance request in response to a user's press of a request switch, etc. (step S101). Then, the controller 320 transmits a request for maintenance work to the maintenance server 400 (step S102).

In response to the request, the maintenance server 400 inquires whether there is an operator who can be assigned to the operator information processing device. If there is no assignable operator (step S201, No), for example, the maintenance server 400 waits for a predetermined period of time. On the other hand, if there is an assignable operator (step S201, Yes), the maintenance server 400 assigns an assignable operator (step S202). This establishes a session between the user and the operator.

The above is an example of the operation when establishing a session. Next, with reference to FIG. 5, an example of the operation after the session is established will be described.

Referring to FIG. 5, if a switch included in the switch set 310 receives an input (step S302, Yes) while a session is being established (step S301, Yes), the controller 320 responds to the received input. Execution of the maintenance function is started (step S303). For example, when the video transmission switch 311 receives an input, the controller 320 transmits and receives the video signal between the connected devices 200 and controls the video signal transmission destination to start transmitting the video signal to the maintenance server 400. . Further, for example, when the operation acceptance switch 312 receives an input, the controller 320 accepts the operation signal received from the maintenance server 400 and transmits the accepted operation signal to the connected device 200 or the like.

For example, input is accepted while the session is being established. When the session ends (step S301, No), reception of input to each switch included in the switch set 310 ends, for example. Note that it may be configured to always accept input to each switch included in the switch set 310 regardless of whether a session is being established or not.

In this way, the KVM switch 300 includes the switch set 310. According to such a configuration, the KVM switch 300 can, in response to an input to the switch set 310, start executing a maintenance function in accordance with the received input. As a result, by using the KVM switch 300, it is possible to easily select the functions to be enabled when receiving services such as maintenance work, and it is possible to easily reflect the user's wishes. Further, according to the above configuration, since execution can be selected for each maintenance function, the user's wishes can be accurately reflected.

Furthermore, by providing the KVM switch 300 with the switch set 310, it is possible to establish a session and start executing the maintenance function, for example, before the information processing device that is the connection destination device 200 starts up. As a result, for example, the startup screen of a BIOS (Basic Input Output System), which is started before the OS (Operating System), can be easily checked on the operator device 500. This allows for more accurate maintenance work.

[Second embodiment]

Further, the switch device 600 can realize the functions of the switch section 621 and the execution section 622 shown in FIG. 7 by the CPU 601 acquiring the program group 604 and executing the program group 604. Note that the program group 604 is stored in the storage device 605 or ROM 602 in advance, for example, and is loaded into the RAM 603 or the like by the CPU 601 and executed as necessary. Further, the program group 604 may be supplied to the CPU 601 via the communication network 611, or may be stored in the recording medium 610 in advance, and the drive device 606 may read the program and supply it to the CPU 601.

Note that FIG. 6 shows an example of the hardware configuration of the switch device 600. The hardware configuration of the switch device 600 is not limited to the above case. For example, the switch device 600 may be configured from part of the configuration described above, such as not including the drive device 606.

The execution unit 622 executes the maintenance function for which the switch unit 621 has received input from among the plurality of maintenance functions. For example, the execution unit 622 can be configured not to execute the corresponding maintenance function until the switch unit 621 receives an input.

In this way, the switch device 600 includes a switch section 621 and an execution section 622. According to such a configuration, the execution unit 622 can execute the maintenance function whose input is received by the switch unit 621 among the plurality of maintenance functions. As a result, the functions to be enabled can be easily selected, and the user's wishes can be easily reflected.

Note that the above-described switch device 600 can be realized by incorporating a predetermined program into an information processing device such as the switch device 600. Specifically, a program according to another embodiment of the present invention provides at least one of a plurality of maintenance functions for use in remotely controlling an information processing device such as the switching device 600 to perform maintenance work on a device to be maintained. This is a program for realizing processing that accepts input to enable the maintenance function and executes the maintenance function for which the input has been received from among multiple maintenance functions.

Further, the execution method executed by the information processing device such as the switch device 600 described above is as follows.
