Next, the configuration of the major parts of the electrical system of the cloud server 14, the administrator terminals 15, and the communication terminal 16 in the image forming system 10 according to the present exemplary embodiment will be described.
The cloud server 14 according to the present exemplary embodiment includes, as illustrated in
With the above configuration, the cloud server 14 according to the present exemplary embodiment executes, with the CPU 14A, access to the ROM 14B, RAM 14C, and storage 14D, obtaining of various types of data via the operation unit 14E, and displaying of various types of information on the display 14F. The cloud server 14 also executes control of, with the CPU 14A, the transmission/reception of communication data via the communication line interface unit 14G.
In the image forming system 10 according to the present exemplary embodiment configured as above, for example, the image forming devices 12 and the administrator terminals 15 are provided in the company. Then, the use of each image forming device 12 is allowed from the outside using the communication terminal 16 via the cloud server 14.
The cloud server 14 provides the function of a virtual device that functions as an image forming device 12 in conjunction with the image forming device 12. That is, in the image forming system 10 according to the present exemplary embodiment, the CPU 14A on the cloud server 14 side functions as a virtual device that is provided one-to-one with a physical device, and that mediates the transmission/reception of information between an application and the physical device. In the following description, an image forming device 12 as an example of a physical device may be referred to as a real device 12.
A virtual device 50 synchronizes with the real device 12 with predetermined timing. An example of data to be synchronized includes meta data such as log data, status data, setting information, and machine information including a device name and a model name. When the virtual device 50 and the real device 12 are synchronized, it becomes possible to remotely view the status or change the settings of the real device 12 using the communication terminal 16 or the like.
Moreover, the virtual device 50 performs processing with external services via an application programming interface (API). Examples of external services include a machine management service and a printing service.
The machine management service allows a machine administrator who is at a different office or in a different country to access the machine management service to check the status or change the settings of the machine. The machine management service transmits and receives information to and from the virtual device 50. When the machine management service sends a status checking request to the virtual device 50, the virtual device 50 returns the status information. When the machine management service sends a setting change request to the virtual device 50, the virtual device 50 updates the setting information. When synchronized with the virtual device 50, the real device 12 obtains the updated setting information and changes the settings of the real device 12.
The printing service allows a mobile terminal such as the communication terminal 16 to upload print data to the printing service, and prints it on the real device 12 having obtained a print job via the virtual device 50.
By working on the virtual device 50 corresponding to the real device 12 without going to a place where the real device 12 is installed, the worker is able to perform maintenance work on the real device 12.
Upon acceptance of a maintenance instruction to perform maintenance work, the worker is able to work on the virtual device 50 corresponding to the real device 12 by following the following procedure.
Therefore, in the present exemplary embodiment, the information processing program stored in the cloud server 14 accepts a maintenance instruction for performing maintenance work on a target device, which is one of a plurality of image forming devices 12, permits a worker who is able to work on a plurality of virtual devices 50 to perform, as maintenance work, only work on a virtual device 50 corresponding to the target device, and prohibits the worker from working on a virtual device 50 corresponding to a non-target device other than the target device among the plurality of image forming devices 12.
Next, processing performed in the image forming system 10 according to the present exemplary embodiment will be described.
When the real device 12A is installed in the office of Company X and the real device 12B is installed in the office of Company Y, the worker is able to work on the virtual device 50A corresponding to the real device 12A and the virtual device 50B corresponding to the real device 12B by following the following procedure.
Next, a procedure in which the administrator instructs the worker to perform maintenance work on a target device will be described.
Administrator A instructs the worker to perform maintenance work on the real device 12A as a target device in accordance with the following procedure. Hereinafter, an instruction given by an administrator to a worker to perform maintenance work will be referred to as a maintenance instruction.
Next, the case in which the worker works on the virtual device 50A corresponding to the real device 12A will be described.
Upon storage of the instruction information in the worker database 300, the worker is enabled to work on the virtual device 50 corresponding to the target device by performing processing in accordance with the following procedure.
Next, specific processing performed by the cloud server 14 in the image forming system 10 according to the present exemplary embodiment configured as described above will be described.
In step S100, the CPU 14A waits until accepting a maintenance instruction from a target device, which is one of a plurality of real devices 12, to perform maintenance work on the target device.
In step S102, the CPU 14A stores, in the worker database 300, instruction information according to the maintenance instruction and the fact that the situation is prohibited in association with physical device information identifying the target device.
In step S104, the CPU 14A notifies the communication terminal 16 of the instruction information (instruction content, specified period, and permitted range) according to the maintenance instruction and virtual device information identifying the virtual device 50 corresponding to the target device.
In step S106, the CPU 14A waits until accepting, from the communication terminal 16, an application for permission to perform work of the instruction content included in the instruction information whose notice has been given on the virtual device 50 corresponding to the target device in the specified period. Upon acceptance of the application for permission from the communication terminal 16 (YES in step S106), the CPU 14A proceeds to step S108.
In step S108, the CPU 14A transmits the application for permission accepted from the communication terminal 16 to the target device.
In step S110, the CPU 14A waits until accepting, from the target device, a notice of permission for performing work of the instruction content on the virtual device 50 corresponding to the target device in the specified period. Upon acceptance of an instruction from the target device to permit work of the instruction content to be performed on the virtual device 50 corresponding to the target device in the specified period (YES in step S110), the CPU 14A proceeds to step S112.
In step S112, the CPU 14A updates, in the worker database 300, the situation stored in association with the instruction information according to the application for permission from prohibited to permitted.
In step S114, the CPU 14A notifies the communication terminal 16 that work of the instruction content is permitted to be performed on the virtual device 50 corresponding to the target device in the specified time.
In step S116, the CPU 14A waits until accepting work on any virtual device 50 from the communication terminal 16. In other words, the CPU 14A waits until the worker attempts to execute work on any virtual device 50. Upon acceptance of work on any virtual device 50 from the communication terminal 16 (YES in step S116), the CPU 14A proceeds to step S118.
In step S118, the CPU 14A determines whether the accepted work is work on the virtual device 50 corresponding to the target device. Specifically, the CPU 14A determines whether virtual device information identifying the virtual device 50 on which work has been accepted in step S116 is stored in advance in association with worker information identifying the worker in the worker database 300. In the case where the accepted work is work on the virtual device 50 corresponding to the target device (YES in step S118), the CPU 14A proceeds to step S120. In contrast, in the case where the accepted work is not work on the virtual device 50 corresponding to the target device (NO in step S118), that is, in the case where the accepted work is work on a virtual device 50 corresponding to a non-target device other than the target device, the CPU 14A proceeds to step S124.
In step S120, the CPU 14A determines whether the date and time at which the work has been accepted is within the specified period. Specifically, the CPU 14A determines whether the date and time at which the work has been accepted in step S116 is within the specified period stored in advance in association with the worker information identifying the worker and the virtual device information in the worker database 300. In the case where the date and time at which the work has been accepted is within the specified period (YES in step S120), the CPU 14A proceeds to step S122. In the case where the date and time at which the work has been accepted is outside the specified period (NO in step S120), the CPU 14A proceeds to step S124.
In step S122, the CPU 14A determines whether the situation is stored as permitted. Specifically, the CPU 14A determines whether the situation stored in association with the worker information identifying the worker, the specified period, and the virtual device information in the worker database 300 is stored as permitted. In the case where the situation is stored as permitted (YES in step S122), the CPU 14A proceeds to step S128. In contrast, in the case where the situation is not stored as permitted (NO in step S122), the CPU 14A proceeds to step S124.
In step S124, the CPU 14A notifies the communication terminal 16 that the work on the virtual device 50 is prohibited.
In step S126, the CPU 14A notifies the administrator terminal 15 owned by the administrator who manages the target device as a predetermined user that the worker has not executed the work on the virtual device 50 corresponding to the target device within the specified period. Then, the CPU 14A ends the information processing. That is, the CPU 14A prohibits the work on the virtual device 50 that the worker attempted to execute.
In step S128, the CPU 14A notifies the target device that the worker is permitted to work on the virtual device 50 corresponding to the target device within the specified time, and permits the work on the virtual device 50 that the worker attempted to execute.
In step S130, the CPU 14A waits until the worker ends the work on the virtual device 50 corresponding to the target device. When the worker ends the work on the virtual device 50 corresponding to the target device (YES in step S130), the CPU 14A proceeds to step S132.
In step S132, the CPU 14A notifies the administrator terminal 15 owned by the administrator who manages the target device that the worker has ended the work on the virtual device 50 corresponding to the target device.
In step S134, the CPU 14A waits until accepting an instruction from the administrator terminal 15 to delete the instruction information. Upon acceptance of an instruction from the administrator terminal 15 to delete the instruction information (YES in step S134), the CPU 14A proceeds to step S136.
In step S136, the CPU 14A deletes the instruction information and the situation according to the application for permission in the worker database 300. As a result of this processing, when the worker ends the work on the virtual device 50 corresponding to the target device, the CPU 14A is able to prohibit the worker from performing the permitted work on the virtual device 50. Then, the information processing ends.
Although the example in which, when the worker ends the work on the virtual device 50 corresponding to the target device, the cloud server 14 prohibits the worker from performing the permitted work on the virtual device 50 has been described in the above exemplary embodiment, this is not the only possible case. For example, when the specified period has elapsed, the cloud server 14 may prohibit the worker from performing the permitted work on the virtual device 50. In this case, information processing in
In step S131, the CPU 14A waits until the specified period has elapsed. When the specified period has elapsed (YES in step S131), the CPU 14A proceeds to step S133.
In step S133, the CPU 14A notifies the administrator terminal 15 owned by the administrator who manages the target device that the specified period has elapsed.
Note that, in the above exemplary embodiment, the cloud server 14 accepts a maintenance instruction from the administrator who manages the real device 12 via the user interface 22A. However, this example is not the only possible case. Alternatively, the cloud server 14 may accept a maintenance instruction from a user who uses the real device 12 via the user interface 22A. Moreover, the cloud server 14 may accept a maintenance instruction from the administrator terminal 15 owned by the administrator who manages the real device 12.
In the above exemplary embodiment, after accepting the maintenance instruction, when the cloud server 14 accepts a notice of permission for work to be performed on the virtual device 50 corresponding to the target device in the specified period, the cloud server 14 permits the worker to perform the work. However, this example is not the only possible case. Regardless of whether the notice has been accepted from the target device, the cloud server 14 may permit the work to be performed on the virtual device 50 corresponding to the target device in the specified period.
In the above exemplary embodiment, a maintenance instruction includes a specified period for which work on the virtual device 50 is permitted. However, this example is not the only possible case. A maintenance instruction need not include a specified period.
In the above exemplary embodiment, the cloud server 14 notifies the administrator who manages the target device when the worker attempts to execute work on a virtual device 50 corresponding to a non-target device. However, this example is not the only possible case. The cloud server 14 notifies the administrator who manages the non-target device when the worker attempts to execute work on a virtual device 50 corresponding to a non-target device. In the case where the user who uses the real device 12 gives a maintenance instruction, the cloud server 14 may notify the user when the worker attempts to execute work on a virtual device 50 corresponding to a non-target device. In this case, the cloud server 14 may display, on the user interface 22A of the target device, that the worker has not executed the work on the virtual device 50 corresponding to the target device in the specified period
In the above exemplary embodiment, after the specified period has elapsed or after the worker has ended the work on the virtual device 50 corresponding to the target device, when an instruction to delete the instruction information is accepted from the administrator terminal 15, the cloud server 14 deletes the instruction information. However, this example is not the only possible case. After the specified period has elapsed or after the worker has ended the work on the virtual device 50 corresponding to the target device, regardless of whether the above instruction has been received from the administrator terminal 15, the cloud server 14 may delete the instruction information.
Although the image forming devices 12 have been described as an example of physical devices in the above exemplary embodiment, physical devices are not limited to the image forming devices 12. For example, other devices such as image processing devices may be applied as physical devices.
In the embodiments above, the term “processor” refers to hardware in a broad sense. Examples of the processor include general processors (e.g., CPU: Central Processing Unit) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable logic device).
In the embodiments above, the term “processor” is broad enough to encompass one processor or plural processors in collaboration which are located physically apart from each other but may work cooperatively. The order of operations of the processor is not limited to one described in the embodiments above, and may be changed.
In addition, processing performed by each unit of the image forming system 10 according to the above exemplary embodiment may be processing performed by software, processing performed by hardware, or processing that combines both. Moreover, processing performed by each unit of the image forming system 10 may be stored as a program on a storage medium to be distributed.
The present disclosure is not limited to the above, and needless to say, in addition to the above, the present disclosure may be implemented in various modifications within a range not deviating from the gist thereof.
The foregoing description of the exemplary embodiments of the present disclosure has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art. The embodiments were chosen and described in order to best explain the principles of the disclosure and its practical applications, thereby enabling others skilled in the art to understand the disclosure for various embodiments and with the various modifications as are suited to the particular use contemplated. It is intended that the scope of the disclosure be defined by the following claims and their equivalents.
