| 摘要 |
The invention concerns a computer-assisted device for detecting the cause of an incident in a technical plant, the incident possibly triggering deceleration of the technical plant in an operationally reliable state of the plant. The device comprises the following components: a) a plant-specific incident decision tree (STEB) stored in a memory (16); b) means (14a to 14c) for linking, in a manner which can be differentiated in terms of time, plant top signals (8a to 8c), which can be measured even in the event of an incident, to decision criteria arranged in the incident decision tree (STEB) in a logical hierarchy; c) means (14a to 14c) for triggering a decision locating the cause of the incident according to the result of the preceding linkage and a possible further decision path, following the preceding linkage in a logical hierarchy, in the incident decision tree (STEB); and d) means (18) for displaying the corresponding incident decision tree (STEB). |
