Description

  The present invention relates to an event record display device for displaying and recording plant events in an office.

  For example, a power plant as an office has a plurality of plants such as No. 1 and No. 2, and each plant is composed of a plurality of devices belonging to the plant. A control computer and various equipment control devices are provided for each plant. Each device belonging to each plant is equipped with various sensors for control or monitoring, and data collected from these sensors is used for real-time processing by a control computer or various device control devices, respectively. Yes.

  On the other hand, the power plant as a whole is usually equipped with one management computer, and as an event record display device, it performs aggregation processing using data for a period such as hourly or daily and can be used as log data or specified He focuses on data and monitors time-series trends in data. In the aggregation process, the total, average, maximum, minimum, etc. of data are calculated.

  Plant data and log data to be aggregated by the event record display device are transmitted from the control computer and various device control devices to the event record display device and accumulated as history data. In addition, it captures various plant events from the data collected from various plant sensors, creates message data, sends it to the typer output and data server as character string data for event messages, and as historical data Accumulated.

Here, the plant data collected in the site (business office) can be immediately transmitted to the data center side, and the transmitted plant data can be stored on the data center side at any time and appropriately managed ( For example, see Patent Documents 1 and 2).

  However, since the transmission between the control computer and the event record display device is a low-speed periodic transmission, if the plant state changes in a time shorter than the transmission cycle interval and returns to the original state, the change over time I can not catch.

  In addition, the control computer collects and manages the data that comes from the sensors installed in the various devices attached to the plant, but not all the plant status is output as a message. May be ignored. Therefore, in reality, it is not possible to grasp all plant state changes and events only by message data output from the control computer.

  Since the event message is a typer output, when checking a past event, the typer paper is referred to, so it takes a lot of effort to check the target event message. In addition, since the message data stored as history data as character strings in the data server of the event record display device is transmitted at regular intervals, messages during regular intervals may be lost and events occurring in the plant may not be captured. there were.

  In addition, even if the target message is found, if there are multiple causes, in order to investigate the cause that caused the event, the cause must be identified unless all the factors are investigated. Because it was not possible, it took a lot of effort. In addition, since there is no message output that integrates the entire office, it is possible to easily grasp messages regarding the operating status of the entire office (for example, the amount of gas emissions), the output value of the entire office, plant efficiency, etc. There wasn't.

  An object of the present invention is to provide an event record display device capable of displaying or reproducing all events occurring in a plant as message data and easily analyzing various events occurring in the plant. is there.

  The event record display device of the present invention includes a data transmission means for fetching plant data detected by a control computer or a plant sensor for performing plant monitoring control at a predetermined cycle, and accumulation of plant data fetched by the data transmission means. Data storage means to perform, data search means for performing data search from plant data accumulated in the data storage means in accordance with search condition data set by an operator, and event interpretation condition data preset from search result data in the data search means In accordance with the present invention, there are provided event data creating means for creating an event message and output means for displaying and outputting the event message created by the event data creating means.
