  FIG. 16 illustrates a configuration example of the plant data database 104 stored in the auxiliary storage unit 53.

  The first line of the plant data database 104 in FIG. 16 describes a parameter code that is a code for identifying a parameter necessary for grasping the tendency of the plant 13. The parameter code is “B001”, “B002”, “B003”... Are sequentially described.

  On the other hand, in the first column of the plant data database 104 of FIG. 16, the time (or the magnetic disk 42, the optical disk 43, the magneto-optical disk 44, the semiconductor memory 45, etc. in the plant 13 is transmitted to the plant information providing apparatus 11). (Time recorded on the external recording medium) is described, and “t1”, “t2”, “t3”, “t4”... Are sequentially described as times.

  It is assumed that the time width Δt at times “t1”, “t2”, “t3”, “t4”. In other words, in the plant data acquisition unit 51, for example, plant data that is data related to the plant 13 transmitted from the plant 13 via the post-communication unit 40 via radio (broadcast radio wave) or the network 12, or the drive Plant data, which is data relating to the plant 13 supplied from the magnetic disk 42, the optical disk 43, the magneto-optical disk 44, and the semiconductor memory 45 via 41, is sequentially acquired with a predetermined time width Δt, and plant data is stored in the plant data database 104. Are sequentially stored with a predetermined time width Δt.

  In the case of the plant data database 104 of FIG. 16, “X1t1”, “X1t2”, “X1t3”, and “X1t4” are stored as data values related to the parameter corresponding to the parameter code “B001” from time t1 to time t4, respectively.

In addition, it means that the data value related to the parameter identified by the parameter code “B002” has transitioned as “X2t1”, “X2t2”, “X2t3”, “X2t4” from time t1 to time t4. ing.

  In step S <b> 34, the trend determination unit 101 reads the trend determination table 105 stored in advance in the auxiliary storage unit 53.

  FIG. 17 illustrates a configuration example of the tendency determination table 105 stored in advance in the auxiliary storage unit 53.

  In the first to Nth columns of the trend determination table 105 in FIG. 17, “trend determination number”, “parameter code”, “setting value 1”, “setting value 2”,..., “Setting value n” Are associated with each other, and each identifies a number for identifying a tendency determination result, and a tendency of the plant 13 (that is, a tendency of various devices constituting the plant 13, a tendency of functions of the plant 13, etc.). A code for identifying a parameter necessary for the measurement, a first reference value regarding a parameter identified by the parameter code, a variation range, a variation determination time for determining variation, and a second regarding the parameter identified by the parameter code Reference value, fluctuation range, fluctuation determination time for determining fluctuation,..., Nth reference value for the parameter identified by the parameter code, fluctuation range And it shows a variation determination time for determining the variation. Note that the variation determination time for determining variation is an integral multiple of a predetermined time width Δt in which plant data is stored in the plant data database 104. Each fluctuation range is a positive value.

  In the case of the first row of the trend determination table 105, the “trend determination number” is “1”, which indicates that the number for identifying the trend determination result is “1”. The “parameter code” is “B001” and is used to identify a parameter necessary for grasping the tendency of the plant 13 (that is, the tendency of various devices constituting the plant 13, the tendency of the function of the plant 13, etc.). It indicates that the code is “B001”. “Setting value 1” is “Zα1, α1, Tα1”, and the first reference value, the variation range, and the variation determination time for determining the variation for the parameter identified by the parameter code are “Zα1”, “ α1 ”and“ Tα1 ”.

  In the trend determination number 1, for example, when the current time is t4, the current data value corresponding to the parameter code “B001” is X1t4, and Tα1 is twice the predetermined time width Δt, the current data The value X1t4 is larger than the first reference value Zα1, and the difference (X1t4−X1t2) between the current data value X1t4 and the data value X1t2 before the variation determination time Tα1 (2 × Δt) is larger than the variation width α1. At this time, it is determined that the tendency determination result indicating the tendency of the plant 13 is “1” on the assumption that it is higher than the first reference value Zα1 and has an upward (abnormal) tendency. In addition, the current data value X1t4 is larger than the first reference value Zα1, and the difference (X1t4−X1t2) between the current data value X1t4 and the data value X1t2 before the variation determination time Tα1 (2 × Δt) varies. When it is smaller than the width −α1 (that is, the current data value X1t4 is larger than the first reference value Zα1 but smaller than the data value X1t2 at time t2 and the absolute value of the difference between the two data values | X1t4− When X1t2 | is larger than the fluctuation range α1, the tendency determination result indicating the tendency of the plant 13 is “2”, although the value is higher than the first reference value Zα1 but is in a downward (improvement) tendency. It is determined. In other cases, the tendency determination result indicating the tendency of the plant 13 is determined to be “0”, although the value is higher than the first reference value Zα1 but is stable.

  On the other hand, the current data value X1t4 is equal to or smaller than the first reference value Zα1, and the difference (X1t4−X1t2) between the current data value X1t4 and the data value X1t2 before the variation determination time Tα1 (2 × Δt) varies. When it is larger than the width α1, it is determined that the tendency determination result indicating the tendency of the plant 13 is “3”, assuming that it is equal to or less than the first reference value Zα1 and has an upward (normal) tendency. Further, the current data value X1t4 is equal to or smaller than the first reference value Zα1, and the difference (X1t4−X1t2) between the current data value X1t4 and the data value X1t2 before the variation determination time Tα1 (2 × Δt) varies. When the width is smaller than −α1 (that is, the current data value X1t4 is equal to or smaller than the first reference value Zα1 but is smaller than the data value X1t2 at time t2 and the absolute value of the difference between the two data values | X1t4− When X1t2 | is larger than the fluctuation range α1, it is determined that the tendency determination result indicating the tendency of the plant 13 is “4” because it is equal to or less than the first reference value Zα1 but has a downward (normal) tendency. The In other cases, the tendency determination result indicating the tendency of the plant 13 is determined to be “0”, assuming that it is equal to or less than the first reference value Zα1 and is stable.

  The same applies to the second and subsequent rows of the trend determination table 105, and the description thereof will be omitted because it will be repeated.

  In order to determine various variations within the variation determination time, a plurality of setting values can be defined for the parameter code. For example, in the case of the trend determination number 4 in the trend determination table 105 of FIG. 17, two set values corresponding to the parameter code B004, the set value 1 and the set value 2, are defined. In this case, among the plurality of defined setting values, the setting value having a lower number is set to have a higher priority in the tendency determination process. That is, setting value 1 has the highest priority among a plurality of setting values defined.

  When there are a plurality of data values of the same type, it is possible to define a plurality of parameter codes for the tendency determination number. For example, in the case of the trend determination number 4 in the trend determination table 105 of FIG. 17, two parameter codes corresponding to the trend determination number 4 are defined as B004 and B005.

  Thereby, the tendency of the plant 13 can be determined using a plurality of data values, and when these data values show different tendencies, it is possible to determine that the data values are not reliable and cannot be determined. It is. That is, the tendency of the plant 13 can be determined more accurately.

  Furthermore, in the setting values of the tendency determination table 105 in FIG. 17, a reference value (for example, the first reference value, the second reference value, etc.) may not be set, and when the reference value is set, the upper limit It can be set to either the value or the lower limit.

  In the tendency determination table 105, a suitable definition can be made as appropriate in accordance with the characteristics of the plant 13 that transmits or supplies plant data to the plant information providing apparatus 11.

  In the case of the fourth line of the trend determination result in FIG. 18, two parameter codes (B004 and B005) are defined for one trend determination number, and two parameter codes are defined for one parameter code. A set value is defined. At this time, since the setting value with the smallest number is given priority among the plurality of setting values, the tendency determination results in the parameter codes B004 and B005 are both recognized as “2”, and the trend determination in the two parameter codes is also performed. Since the results match, the trend determination result corresponding to the trend determination number 4 is recognized as “2”.

  Thereby, the current tendency of the plant 13, that is, the current tendency of various devices constituting the plant 13, the current tendency of the functions of the plant 13, and the like are determined, and a plurality of determined tendency determination results are stored. Can do.
