  FIG. 1 is a functional block diagram of the data management apparatus 1 in the present embodiment.

  FIG. 2 is an explanatory diagram illustrating an example of various data used in the data management apparatus 1.

  The data management device 1 is a device that manages operation data and test data input from a plant such as a nuclear power plant or a thermal power plant.

  The process input unit 11 inputs plant process data input at regular intervals to the data management apparatus 1. The event determination unit 12 determines whether or not the process data input from the process input unit 11 needs to be saved as event data. When all event data input from the process input unit 11 is stored, the event determination unit 12 may be omitted. As shown in FIG. 2A, for example, the event data is data having information on the state change of the plant and the date and time. The event storage unit 13 stores event data output from the event determination unit 12.

  The historical data processing unit 22 generates historical data by compressing and saving the process data input from the process input unit 11. For example, as shown in FIG. 2B, the historical data is analog or digital continuous data having a storage format different from that of event data, and is data having date and time information. The historical data storage unit 23 stores the historical data output from the historical data processing unit 22.

  The trip sequence processing unit 32 acquires data for a predetermined time before and after the data in which a predetermined trigger has occurred, as shown in FIG. 2C among the process data input from the process input unit 11. The trip sequence storage unit 33 stores trip sequence data output from the trip sequence processing unit 32.

  Based on the data input from the process input unit 11, the diary log calculation unit 42 generates an event log in predetermined time units, for example, as shown in FIG. The diary log storage unit 43 stores diary log data output from the diary log calculation unit 42.

  The dialogue operation unit 14 supplies various instructions received from the operator to the search / save unit 15. The search / save unit 15 edits (adds, changes, deletes, etc.) the title information stored in the title storage unit 16 based on the input from the dialogue operation unit 14. In addition, the search / save unit 15 determines the data conditions to be extracted from the storage units 13, 23, 33, and 43 based on the information supplied from the dialogue operation unit 14 and the information stored in the title storage unit 16.
