PURPOSE:To effectively detect an accident by supervising plant facility equipment according to the degree of secular deterioration in a suitable cycle. CONSTITUTION:A facility accident detecting device 3 is provided with a supervising/collecting device 4, which inputs signals from respective sensors 2a, 2b,... and A/D-converts the signals, an accident deciding device 5, which decides the occurrence of the accident based on data from the supervising/ collecting device 4, a decision result output device 6 to output a decision result, and further a supervisory variable device 7, which alters a plant supervisory cycle based on the accident decision result of the accident deciding device 5. At the beginning of the activation of plant equipment 1a, 1b,... having the small possibility of the accident occurrence, the supervising cycle is made longer, and when the possibility of the accident occurrence becomes larger, the supervising cycle is made shorter. Thus waste to frequently supervise a plant to discover the accident when the accident occurrence possibility is small can be eliminated, and the efficient plant supervision is attained. |
