CHECK DATA MANAGEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To select an optimum approximate curve by the unified decision with any type of check data by adding the contribution weight to perform a multidimensional regression analysis based on the accumulated check data. SOLUTION: The check data obtained by checking the power generation facilities 1 are inputted to a handy terminal 2 by a checking worker and then transferred to a check data input store part 3. Then the check data are stored in a data base 4 together with the information on the facility/checking time, etc. At the same time, the necessary check results are sent to a regression calculation part 5 from the part 3 out of the stored data. The part 5 performs the regression calculation by adding the different contribution weights to the primary, secondary and exponential regression methods respectively. The results of these regression calculations are sent to an approximate curve decision part 8 which selects an approximate curve that is optimum to the object check data based on the correlation coefficient of every approximate curve. The selected approximate curve and the check data are sent to a result output part 6 and shown by a display device 7.
