The communication line 20 may be a shared communication line provided for public flights or an original dedicated communication line. Moreover, it is also possible to mix both.

  As described above, the management center 24 is a facility where the manager 22 who manages the worker 12 resides, and is, for example, a sales office that has jurisdiction over a predetermined area to which the building 16 belongs. The worker 12 usually belongs to this sales office and is dispatched to the building 16 as necessary. The management center 24 may have a function of managing the equipment 18 of the building 16. In this case, the building 16 and the management center 24 are connected via the communication line 20 to monitor the state of the equipment 14 and the presence / absence of an abnormality. The detailed configuration of the management center 24 according to the present invention will be described later.

  Next, the configuration of the computer device 14 according to the present embodiment will be described. The computer device 14 includes a display unit 26, an input unit 28, a recording unit 30, and a control unit 32.

  The display unit 26 is a device that displays a GUI operation of the computer device 14 as an image, and is, for example, a display. The video displayed on the auxiliary display unit 26 includes information such as information acquired from the device 18, information regarding the operation content, or information analyzed in the computer device 14 based on the information.

  The input unit 28 is a device for an operator to input information related to the operation of the computer device 14. For example, the input unit 28 is a mouse, a numeric keypad, a keyboard, or a touch panel integrated with the display unit 26.

  The recording unit 30 is a device that records information. The information recorded in the recording unit 30 includes information related to the device acquired from the device 18, information related to an operation input from the input unit 28, and video information displayed on the display unit 26. Then, the recording unit 30 records information related to the operation from the input unit 28 as an operation event log in association with the time or order in which the information is input. In addition, the recording unit 30 records the video displayed on the display unit 26 as a video log in association with the time when the video is displayed. The operation event log and the video log are associated with each other when the time matches.

  The control unit 32 is a device that controls the entire computer device 14 based on information from the input unit 28 and the recording unit 30.

  Further, the computer device 14 includes a transmission / reception unit (not shown) that is connected to the device 18 and the communication line 20 and can transmit and receive information and signals.

  At the time of work, the computer device 14 is connected to the device 18, and information on the device 18 is acquired by an operation by the worker 12. The acquired information can be analyzed in the computer device 14 by the operation of the worker 12. Such a work process, that is, the operation content is recorded in the recording unit 30 as a video log together with the operation event log. These logs are transmitted to the management center 24 via the communication line 20.

  In the present embodiment, the case where the computer device 14 is portable by the worker 12 has been described. However, the present invention is not limited to this configuration, and the computer device 14 is permanently installed in the building 16 and the device 18 is installed. It may be a monitoring device. In this case, the computer device 14 is always connected to the device 18, can acquire and record information of the device 18, and can transmit the information to the management center 24 via the communication line 20.

  Next, the configuration of the management center 24 will be described. The management center 24 includes a control unit 34, a storage unit 36, an abnormal operation detection unit 38, and an extraction unit 40. The management center 24 is connected to the communication line 20 and can transmit and receive information and signals to and from the computer device 14 (not shown), an input unit for inputting information, and the computer device 14 And a display unit that displays GUI operations as images.

  The control unit 34 is a device that performs control within the monitoring center 24. The control unit 34 may include functions of the abnormal operation detection unit 38 and the extraction unit 40.

  The storage unit 36 is a device that stores information. Information stored in the storage unit 36 includes a standard operation event log and a standard video log. The standard operation event log is recorded as an operation event log in which information related to an operation when the operation of the computer device 14 to be standardized is performed by the input unit 28 in association with the time when the information is input in order. . On the other hand, the standard video log is a video displayed on the display unit 26 for each standard operation, and the standard video log and the standard operation event log are associated with each other by time. The storage unit 36 can also store an operation event log and a video log output from the computer device 14.

  An example of the standard operation event log will be described with reference to FIGS. FIG. 2 is a diagram illustrating an example of the relationship between the operation content and the standard operation event log, and FIG. 3 is a diagram illustrating the procedure of the standard operation in FIG.

  The contents of the operation shown in FIG. 2 are for maintenance work on the device 18, and the worker 12 dispatched to the building 16 operates by connecting the computer device 14 and the device 18.

  Also, the standard operation event log shown in FIG. 2 is an item related to the content of the operation. For example, when the content of the operation is “start software”, the standard operation event log is “normal start”, and is an operation log of the worker 12 that normally starts the software in the computer device 14. An operation procedure is associated with the standard operation event log. Specifically, the content of the operation is set in advance so as to operate in order from “1-1” to “1-7”. However, as shown in FIG. 3, the items “1-2” to “1-5” are determined to be operated without omission between “1-1” and “1-6”. The operations during this period are set in random order.

  In the maintenance work described above, when the worker 12 operates the operation contents shown in FIGS. 2 and 3 in order, it can be said that the series of operations is appropriate. On the other hand, in this work, when the worker 12 does not operate the operation contents in order or when a part of the operation contents is not performed, it can be said that the operation is inappropriate and an abnormal operation. In the present embodiment, the abnormal operation detection unit 38 and the extraction unit 40 can accurately extract the abnormal operation by the worker 12, as will be described below.

  The abnormal operation detection unit 38 compares the operation event log with the standard operation event log, and detects a place where the operation of the worker 12 is different from the standard operation. For example, in “1-6” of FIG. 2, when there is a standard operation event log in which the button “registration” is pressed, but the operation is not in the operation event log, the abnormal operation detection unit 38 sets the worker 12 Information relating to operations performed in the order of the corresponding standard operation event log is detected as a location where the operation is different from the standard operation.

  Then, the extraction unit 40 extracts a video log corresponding to an operation event log that is an abnormal operation detected by the abnormal operation detection unit 38. The extracted video log may be displayed on the display unit of the management center 24. With such a configuration, the administrator 22 can visually and specifically grasp the abnormal operation simply by browsing the extracted video log.

  Further, the extraction unit 40 can extract information related to the operation corresponding to the extracted video log from the operation event log. Thereby, the administrator 22 can confirm not only with an image | video but with a character.

  In addition, the extraction unit 40 can extract a standard video log that can be compared with the extracted video log. Thereby, the manager 22 can confirm the abnormal operation and the standard operation while visually comparing them.

  Further, the extraction unit 40 can extract a standard operation event log corresponding to the extracted standard video log. As a result, the administrator 22 can confirm the standard operation not only with the video but also with the characters.

  Next, the operation of the system 10 of this embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of the operation of the system 10. This operation starts when the operation of the computer device 14 by the worker 12 is completed and the operation event log and the video log recorded in the recording unit 30 of the computer device 14 are taken into the management center 24.

  First, in step S <b> 101, an operation event log and a video log are taken into the management center 24 from the computer device 14. In step S102, the abnormal operation detection unit 38 compares the operation event log with the standard event log, and determines whether or not there has been an abnormal operation in the operation of the worker 12 (step S103).

  If it is determined in step S103 that there is an abnormal operation, the process proceeds to step S104, the video log corresponding to the abnormal operation is extracted by the extraction unit 40, and this control operation ends.

  On the other hand, if it is determined in step S103 that there is no abnormal operation, the process proceeds to step S105, where it is determined that the operation of the worker 12 is appropriate, and this control operation ends.

  According to this system 10, the manager 22 can manage the operation of the computer device 14 by the worker 12 from the remote management center 24, and can easily distinguish whether the work is appropriate or not.

  In the present embodiment, the case where the extraction unit 40 extracts various logs at the time of abnormal operation has been described, but the present invention is not limited to this configuration. Various logs in a predetermined range including the abnormal operation time can be extracted. The predetermined range will be specifically described with reference to FIG.

  FIG. 5 is a diagram illustrating an example of the range of the extracted video log. In this figure, as an example, a case where the extracted log is a video log will be described. However, as described above, various logs, that is, an operation event log, a standard operation event log, and a standard video log may be used.

  In the figure, symbol A is an operation event log corresponding to an abnormal operation, and symbol A 'is a video log corresponding to the operation event log. As shown in this figure, the extraction unit 40 can extract, from the video log, a video at a predetermined time before the time when the abnormal operation occurs. The predetermined time is, for example, 1 minute before and after the abnormal operation time point. As described above, the video log is extracted in a predetermined time range including the abnormal operation time point, so that the manager 22 confirms how the worker 12 performed the abnormal operation. Can be used for planning recurrence prevention measures.

  Further, in the present invention, it may not be the predetermined time, and may be the number of information related to the operation preceding by a predetermined number from the time when the abnormal operation occurs.

  Moreover, it is preferable to set these predetermined ranges arbitrarily. Thereby, the manager 22 can verify the circumstances leading to the abnormal operation more carefully.
