Description

  The present invention relates to a plant monitoring apparatus, and more particularly to a plant monitoring apparatus that can quickly perform an analysis operation when a failure occurs.

  In the plant monitoring apparatus, it is assumed that some kind of failure or failure occurs in the hardware and software. For this reason, the plant monitoring apparatus provided with the function which can perform the analysis at the time of failure generation easily based on the operation and past information which the operator performed is proposed (for example, patent documents 1-5).

  Information on screen operations plays an important role in investigating the cause of failure when it occurs intermittently. The plant monitoring man-machine device collects a screen operation log and screen data displayed at that time and stores the screen operation log at a timing when the screen is operated (for example, Patent Document 6). .

JP-A-6-103122 Japanese Patent Laid-Open No. 8-222295 JP-A-10-301815 JP-A-11-119823 JP 2006-99298 A JP 2011-108157 A

  The plant monitoring man-machine apparatus is configured to store screen operation logs and image data in a one-to-one correspondence. Time information and hardware (H / W) logs generated at that time are not saved. For example, in the case of a failure due to a software (S / W) malfunction, the cause cannot be directly understood from the log, so that manual analysis may be required, and a considerable amount of time is required for the analysis.

  In addition, a method of calculating the frequency from the occurrence of an abnormality in a failure log created at this time by utilizing a recoverable failure experienced in the past is also performed. In this method, logs may be different depending on the software configuration. Since a failure occurs in a different log, the analysis must be performed based on the log. However, the information of the log generated at that time cannot provide sufficient information for analysis.

  The present invention has been made to solve the above-described problems. Hardware and software logs and operation times at the time of failure occurrence, and screen data and operation logs are collected as one piece of information and saved in association with related data at the time of failure, shortening the failure analysis time An object of the present invention is to provide a plant monitoring apparatus that can perform the above-described process.

The plant monitoring device according to the present invention includes a control device that creates and stores an event log when a screen operation is performed, and a screen display device connected to the control device, and the event log includes an ID, It includes a cause, an operation time, a log classification number, and log contents.

  According to the plant monitoring apparatus of the present invention, when a failure occurs due to an operator's operation, not only the time but also the program error, the screen operation status at the time of the error, and the screen displayed at that time are summarized. Can be confirmed. By checking the log at the time when the failure occurred, the log analysis time at the time of the failure can be shortened, so the failure investigation time can be made more efficient.
