PURPOSE:To reduce burden of a supervisory system by judging it an ordinary trouble when time of trouble or number of times of troubles exceeds a set value within a specified time from occurrence of the trouble, and judging it as a momentary trouble when time of trouble and number of times of troubles is less than a set value within a specified time. CONSTITUTION:Trouble information inputted from a terminal 1 is compared with present state of trouble D1 stored in a memory 3 in a status change detecting section 2, and a trouble occurrence signal phi1 or a trouble restoration signal phi2 is sent to an intensive processing section 4. The intensive processing section 4 collates setting time Ts of a setting section 8 and trouble cumulative time of trouble Tn of a timer 6, and if Ts<Tn, it is judged as an ordinary trouble, and the result K1 of processing is outputted. Further, it collates number of times of setting of the setting section 8 and number of times of occurrence of troubles Cn of a counter 5, and if Ts<Tn, the result K1 is outputted as an ordinary trouble. When Ts, Cs are larger than Tn, Cn, it is judged as momentary trouble and the result K2 of processing is outputted. |
