摘要： PURPOSE:To widely and quickly grasp the state of a process plant and the necessary countermeasure operations by applying a knowledge engineering process to systematically perform the diagnosis of the plant abnormality, the make-up of the countermeasures against the abnormality and the synthesization of operating procedures. CONSTITUTION:A plant state deciding part 2 uses a plant signal to decide the present plant state and defines exclusively such modes of the normal opera tion, the abnormality, the trouble, etc. An operating target selection part 3 selects one of plural operating targets. A plant function monitor part 5 monitors and evaluates the nondefectiveness of the plant functions, and an operating procedure deciding part 6 decides the operating procedure necessary for mainte nance and recovery of the abnormal plant function. Then an operating procedureevaluating part 7 excludes the ineffective operating procedure candidates and defines the remaining procedure as the final necessary operating procedure to send it to an operating procedure display part 8. Thus it is possible to properly show those necessary operating procedures to the operator in the order of higher degrees of importance.

摘要： PURPOSE:To grasp the state of a plant and to speed up and secure corresponding operation by discriminating only a really important warning when the plant becomes abnormal, deciding a cause event, and selecting and displaying an operation procedure for stabilizing the current plant state corresponding to the current plant state automatically corresponding to the event. CONSTITUTION:A warning processing part 1 extracts only a warning to be aimed at really among many warnings which are generated at the time of plant abnormality and uses a warning signal S1 and a plant process signal S2 which are generated as a result to obtain a necessary warning by logical operation. A cause event decision part 2 decides the cause event according to the warning to be aimed at and the change of the plant process signal S2. Then when the cause event is decided, an information selection part 5 reads the operation procedure corresponding to the cause event selectively out of a various-procedure-document file 6 where various procedure documents are stored. The read procedure documents are passed through a man machine interface part 8 and offered to a user through, for example, a CRT display device 9, etc.

摘要： PROBLEM TO BE SOLVED: To provide a device for diagnosing a plant, with which the names of events having a high possibility of occurrence can be outputted together with their similarity out of registered cases by successively performing diagnosis online without previously working a large quantity of case data or performing learning processing. SOLUTION: On the basis of signals which are inputted from a signal input part 1 and which indicate the operating state of equipment and a logic stored on a logic database 4, a logic deciding part 3 determines the candidate case group of a plant state. On the basis of a distance between the time sequential data of signals which are inputted from the signal input part and which indicate a process state and the case data of the candidate case group stored on a case database 6, a time sequential waveform judging part 5 judges the plant state by evaluating their similarity. Then, the diagnosed result is displayed out on an output display part 1.

摘要： PURPOSE:To make out a plan for a periodic test including abiding by of rules by making inference by using the knowledge data stored with the restriction conditions, etc., relating to the periodic test and the plant process data base stored with the history, etc., of operation processes. CONSTITUTION:The operation process schedule previously stored in the plant constitution data base 2 is first read in by an inference mechanism 3 and is converted to the form of working memory elements so that the schedule becomes the known fact at the time of starting the planning. The restriction conditions are then read in from the knowledge data base 1 by the mechanism 3 and the range of the term of the test is determined by applying the restriction conditions for the process to the operation process schedule. The restriction conditions for the period of the test are determined by the periodic test history read in from the plant process data base 2. Two kinds of such processing are executed in parallel. The optimum test date which uniformizes operators' load to avoid concentration of the load on the operators for operation control and testing work with time is determined by the optimization conditions read in the data on the periodic test of the determined term from the data base 1. The plan for the periodic test is thus made out.

摘要： PURPOSE:To obtain a conclusion having a larger range of possibility by performing the reasoning based on the similarity between rules in a knowledge base. CONSTITUTION:The state signal S1 of the plant process received from a plant 1 is processed by an input signal processing part 2 and then stored in a data base 3. Then the causal relation of the plant state is reasoned at a state reasoning part 5 by means of a knowledge base 4 together with the reasoning also carried out to secure the operation control guide. Then the degree of assurance is checked to the conclusion, i.e., a result of reasoning and the diagnosis guidance information serving as the result of reasoning is displayed on a CRT of a user interface part 7 when the degree of said assurance is large. While the degree of similarity is calculated at a similarity reasoning part 6 when the degree of assurance is small. Then a rule having a large degree of similarity is displayed via the CRT.

摘要： PURPOSE:To obtain a plant fault analyzer having adaptability by securing the flexible change of the reference value of a limit check method of a plant fault detecting means in response to the situation of a plant. CONSTITUTION:When a transient phenomenon occurs at a signal processor 3 and it is decided from the result of analysis of a fault factor analyzer 4 that said transient phenomenon is not equal to a fault, a state estimating device 5 estimates the plant situation after the transient phenomenon is produced. Then a comparing/deciding device 6 compares the state estimation result given from the device 5 with the latest plant data obtained from a signal input device 2 and decides the presence or absence of a difference obtained from the comparison. If a difference exists, the factor of the transient phenomenon is displayed with lighting on an alarm display device 7 as long as said phenomenon is due to a fault. While the device 6 compares the estimated values of primary parameters such as the neutron flux, furnace core flow rate, etc. with each other, When no difference is detected, a reference value changing device 9 changes the reference value within a reference value preserving device.
