  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a system configuration of a data delivery system according to an embodiment of the present invention.

  As shown in FIG. 1, the data delivery system according to an embodiment of the present invention includes a plurality of data processing servers 10, a plurality of client terminals 20, and a delivery server 40 interconnected by a network 30.

  Each of the plurality of client terminals 20 is an information processing apparatus that generates and transmits a processing request (request) for requesting execution of specific processing for image data, audio data, text data, and the like.

  The distribution server 40 receives a processing request from the client terminal 20, and distributes the received processing request to the data processing server 10 that can execute the processing request among the plurality of data processing servers 10. It is.

  The data processing server 10 is a processing execution device that executes processing based on the received processing request, and is configured to be able to execute processing on various data such as image data, voice data, text data, and the like.

  For example, a certain data processing server 10 is configured to be able to execute certain image processing on the image data, and the other data processing server 10 is configured to be able to execute speech recognition processing on the voice data. Further, as other processing contents that can be executed by the data processing server 10, various processes such as a keyword extraction process for text data, a character recognition process for image data, a process for extracting a characteristic key frame from image data, etc. There is content.

  In the data delivery system of this embodiment, the MQTT performs Pub / Sub type (publish / subscribe type: publication / subscribe type) data delivery between the client terminal 20, the delivery server 40, and the data processing server 10. A message called processing request is transmitted and received via a communication protocol called (Message Queue Telemetry Transport).

  FIG. 2 shows a conceptual diagram of a method for transmitting / receiving a processing request (message) in the data distribution system of this embodiment.

  In the data distribution system shown in FIG. 2, processing requests are transmitted and received between the client terminal 20 and the data processing server 10 in the form of a Pub / Sub type messaging model.

  Here, the client terminal 20 functions as a publisher that issues a processing request. The distribution server 40 functions as a broker that distributes a processing request from the client terminal 20 to the data processing server 10 that can execute the processing request. Furthermore, the data processing server 10 functions as a subscriber (subscriber) that receives from the distribution server 40 only a processing request that can be executed in its own device.

  The concept of the processing request transmission / reception method in the data distribution system of this embodiment functioning as such a Pub / Sub type messaging model will be described with reference to FIG.

  First, each of the plurality of data processing servers 10 registers, in the distribution server 40, information on the types of processing requests that can be processed in the own device as a filter.

  When the client terminal 20 transmits the processing request specifying the processing content to the distribution server 40, the distribution server 40 transmits the processing request matching the filter registered by the data processing server 10 to the data processing server 10. .

  By performing such processing, in the client terminal 20, without specifying to which data processing server 10 the generated processing request is to be transmitted, the generated processing request can be data that can execute the processing request. It is transmitted to the processing server 10.

  Also, the data processing server 10 can receive a processing request that can be executed by the own device without requiring knowledge about the client terminal 20.

  That is, without the client terminal 20 and the data processing server 10 holding each other's information, the generated processing request generated in the client terminal 20 is appropriately distributed to the data processing server 10 capable of executing the processing request. Will be.

  When the execution of the received processing request is completed, the data processing server 10 that has executed the received processing request returns the processing result as a response message to the client terminal 20 that has generated the received processing request. Note that when this response message is sent back, the data processing server 10 functions as a publisher (publisher), and the client terminal 20 functions as a subscriber (subscriber).

  Here, the client terminal 20 receives the response message from the data processing server 10 and grasps the completion of the generated processing request.

  However, when the data processing server 10 that executes the processing request to be transmitted from the client terminal 20 is executing another processing request with a large processing load, the client terminal 20 sends the processing request to the data processing server 10. Even if a process request is sent, there may be cases where the process is waiting for execution. In such a case, even if a processing request is transmitted from the client terminal 20, a response message indicating that the processing has been completed cannot be received for a while.

  Further, when there is no data processing server 10 capable of executing the processing request to be transmitted among the plurality of data processing servers 10, even if the processing request is transmitted to the distribution server 40 in the first place, Processing requests are never executed.

  In such a case, although the client terminal 20 transmits the processing request, if the processing for the transmitted processing request is not completed within the intended time, the client terminal 20 times out. Then, the Klein terminal 20 may determine that the transmitted processing request is not processed normally and retransmit the processing request having the same processing content again.

  However, when the data processing server 10 is not in the state capable of executing the processing request, even if the processing request of the same processing content is transmitted again, the capacity of the communication line such as the network 30 is merely wasted.

  Therefore, in the data distribution system according to the present embodiment, the processing request to be transmitted is sent to the data processing server 10 by performing the processing described later, and the processing request to be transmitted is executed when the specific processing is executed. By confirming that the data processing server 10 can execute at the present time, transmission is performed to prevent the above-described waste.

  Next, the hardware configuration of the client terminal 20 in the data delivery system of this embodiment is shown in FIG.

  As shown in FIG. 3, the client terminal 20 performs data transmission and reception with a CPU 11, a memory 12, a storage device 13 such as a hard disk drive (HDD), and an external device via the network 30. It has an interface (IF) 14, a touch panel or liquid crystal display, and a user interface (UI) device 15 including a keyboard. These components are connected to each other via a control bus 16.

  The CPU 11 executes predetermined processing based on a control program stored in the memory 12 or the storage device 13 and controls the operation of the client terminal 20. In the present embodiment, the CPU 11 is described as reading and executing a control program stored in the memory 12 or the storage device 13, but the program is stored in a storage medium such as a CD-ROM and stored in the CPU 11. It is also possible to provide.

  FIG. 4 is a block diagram showing a functional configuration of the client terminal 20 realized by executing the control program.

  As shown in FIG. 4, the client terminal 20 of the present embodiment includes a processing request transmission unit 31, a control unit 32, a display unit 33, a data storage unit 34, and an operation input unit 35.

  The processing request transmission unit 31 sends the processing request generated in the client terminal 20 to the data processing server 10 that is a processing execution device via a communication protocol for performing Pub / Sub type data distribution as described above. Send. For example, the processing request transmission unit 31 transmits a processing request using any one of image data, audio data, and text data as processing target data.

  The display unit 33 is controlled by the control unit 32 and displays various information to the user. The operation input unit 35 inputs various types of operation information performed by the user.

  Based on various operation information input from the operation input unit 35, the control unit 32 performs various controls such as processing for transmitting a processing request and displaying processing results for the transmitted processing request on the display unit 33. . The data storage unit 34 temporarily stores the generated processing request and stores various data.

  When the process request transmitting unit 31 attempts to transmit a process request (first process request) for executing a specific process content to the data processing server 10, the process request is a dummy process having a smaller processing load than the process request. A request (second processing request) is transmitted to the data processing server 10. Then, when the processing result for the dummy processing request in the data processing server 10 is normally obtained, the processing request transmission unit 31 transmits the processing request to be transmitted to the data processing server 10.

  Here, the dummy process request is a process request that is the same as or similar to the process request to be transmitted. For example, the dummy processing request is a simulated processing request that does not include processing target data. That is, the dummy processing request is a confirmation processing request for confirming whether or not the processing request to be actually transmitted can be processed at any one of the data processing servers 10 at the present time.

  For example, when the processing request to be actually transmitted is a certain image data and the compression processing for the image data, the dummy processing request does not include the processing target image data at all, and the processing content is the compression processing. For example, a processing request or a processing request for processing image data to be processed as temporary image data with a small data amount can be used.

  The processing request transmission unit 31 does not always transmit the dummy processing request before transmitting all the processing requests, but only in advance to transmit the processing request that matches a certain condition. You may make it transmit.

  For example, when the processing load of a processing request to be actually transmitted is larger than a preset value, the processing request transmission unit 31 transmits a dummy processing request before transmitting the processing request. That is, when the processing load of the processing request to be actually transmitted is smaller than the preset value, the processing request transmitting unit 31 does not transmit the dummy processing request before transmitting the processing request, but actually transmits the processing request. The processing request that was going to be transmitted is transmitted as it is.

  In addition, when the current time is included in a preset time zone, the processing request transmission unit 31 may transmit the dummy processing request before transmitting the processing request to be actually transmitted. The reason for doing this is that, for example, when a communication line such as the network 30 is congested in a specific time zone, the processing request transmission unit 31 is only in advance when trying to transmit a processing request in that time zone. A dummy processing request is transmitted, and it is confirmed that the processing request is transmitted to the data processing server 10 without any problem due to congestion of the communication line.

  In addition, the processing request transmission unit 31 includes, in the history information of the processing result in the past, information indicating that the processing result corresponding to the processing request having the same or similar processing content as the processing request to be actually transmitted is not obtained normally. In such a case, the dummy processing request may be transmitted before the processing request is transmitted.

  Specifically, when the history information of the processing result of the processing request transmitted in the past is stored in the data storage unit 34 and the control unit 32 tries to transmit the processing request via the processing request transmission unit 31, The processing result of the processing request having the same or similar processing content as the processing request is acquired by referring to the history information. Then, the control unit 32 refers to the acquired history information, and when a processing request identical or similar to the processing request to be transmitted has an error in the past, the dummy processing is performed before the processing request is transmitted. The request is transmitted, and it is confirmed in advance whether the data processing server 10 can process the processing request to be transmitted.

  There are various methods for determining whether or not the processing result for the transmitted processing request has been normally obtained.

  For example, when a response to the effect that the processing for the dummy processing request has been successfully executed can not be acquired within a preset time, the processing request transmission unit 31 determines that the processing result has not been successfully obtained.

  In addition, when the processing result for the dummy processing request is not obtained, the processing request transmission unit 31 retransmits the dummy processing request after a preset time, and the number of transmissions of the dummy processing request exceeds the preset number. In this case, it may be determined that the processing result has not been obtained normally.

  Next, the operation of the client terminal 20 in the data delivery system of the present embodiment will be described in detail.

  FIG. 5 is a flowchart for explaining the operation of the client terminal 20. In the flowchart of FIG. 5, a case will be described in which a dummy processing request is transmitted only when the processing load of the processing request to be transmitted is larger than a predetermined value.

First, the control unit 32 determines whether or not the processing load of a processing request to be transmitted to the data processing server 10 is larger than a predetermined value (step S101).
Here, when the processing load of the processing request to be transmitted is not larger than the predetermined value (No in step S101), the processing request transmission unit 31 transmits the processing request to be transmitted to the distribution server 40 as it is ( Step S107).

  Then, when the processing load of the processing request to be transmitted is larger than the predetermined value (yes in step S101), the processing request transmission unit 31 sends a dummy processing request whose processing load is lighter than the processing request to the distribution server 40. It transmits (step S102).

  Then, when the processing result for the transmitted dummy processing request is received from the data processing server 10 (step S103), the control unit 32 determines whether the received processing result is the expected processing result (step S104).

  Here, whether or not the expected processing result is obtained is determined based on, for example, whether or not the scheduled processing result is obtained within a preset time after transmitting the dummy processing request. .

  Then, when the received processing result is not the expected processing result (No in step S104), the processing request transmission unit 31 repeats the transmission of the dummy processing request until the number of transmissions reaches a predetermined number or more (step S105). When the number of transmissions of the dummy process request is equal to or greater than the predetermined number (Yes in Step S105), the control unit 32 reports an error to the user via the display unit 33 or the like (Step S106).

  Here, the predetermined number of times does not have to be a plurality of times, and by making the predetermined number of times once, an error report is performed if the processing result for the dummy processing request is not the expected processing result even once.

  If the received processing result is the expected processing result (yes in step S104), the processing request transmission unit 31 transmits the processing request that was to be transmitted first to the distribution server 40 (step S107).

  Then, the control unit 32 receives the processing result for the transmitted processing request (step S108), and when the received processing result is the expected processing result (yes in step S109), the processing result is displayed on the display unit 33. This is reported to the user by displaying it on the screen (step S110).

  When the received processing result is not the expected processing result (No in step S109, the control unit 32 reports an error to the user by displaying the processing result on the display unit 33 or the like (step S106).
