  • the priority change unit 10 dynamically changes the priority of each data recorded in the priority model management database 12 based on the priority change command 100. For example, the priority of data related to an abnormal device is changed to a higher priority depending on the reason for the need to change the priority. However, in cases where the processing load on the priority change unit 10 becomes large, the priority change operation of the priority change unit 10 may be such that only a change flag is added to the priority of the priority change data and the priority related data recorded in the priority model management database 12, and the load level adjustment unit 14 converts the changed priority based on the change flag (including rewriting the actual numerical value).
  • the load level adjustment unit 14 can later change the priority of other data by tracing the relationship from several data with high priority, thereby reducing the processing load on the priority change unit 10.
  • the priority change unit 10 can also change the priority of data (priority related data) related to that data (priority change data) according to the degree of relevance (simultaneously or sequentially in time).

In addition, the load level adjustment unit 14 considers the relationship (degree of association) between data when selecting data to be sent to the display device 20.
  • the load level adjustment unit 14 determines that, of data A and data ⁇ , which have the same priority, data A has a higher priority because its related data has a higher priority (in this case, the sum of the priorities of the related data is larger), and selects it.
  • the sum of the priorities of the related data is used as the criterion for judgment, but if the number of related data is different, the average priority may be used, or the priorities of the related data may be converted by weighting them according to the degree of relevance.

  • the priority change unit 10 changes the priority of each of the priority change data and its priority related data.
  • the priority change unit 10 then waits until the next priority change command 100 is received (step ST04 in FIG. 2).
  • the priority change command 100 may be issued again, for example, when the abnormality in the device is resolved. In other words, when it is no longer necessary to maintain the high priority of the data related to the device in which the abnormality occurred, the priority change command 100 is issued to assign a priority appropriate to the next state (i.e., when the system is normal) to each piece of data, and as a result, the priority of each piece of data may be reset for each event (such as an abnormality in the device).

  • the system load does not cause problems during normal processing as long as all data is processed normally, but the load may become high when the amount of data requiring processing increases due to an abnormality or other reason.
  • the load level adjustment unit 14 judges whether the system load level is high or not (step ST11). For this judgment, for example, a method of setting a threshold value for the CPU load or the drawing load, etc., and detecting whether the threshold value has been exceeded can be considered. If the system load is not high, the operation is terminated.
  • the load level adjustment unit 14 selects data (processing reduction data) that has the lowest priority from the priority model management database 12 and therefore reduces processing (step ST12).
