Abstract
PURPOSE: To estimate a faulty location immediately at a fault by generating a table representing the relation of connection between equipments in a network, calculating in advance the effecting range of the fault at the occurrence of the fault at every equipment and estimating the fault location based thereon.
CONSTITUTION: A diagnostic processing section 21 reads the device constitution information 44 stored in an equipment constitution file 28 to group the constitution equipments. Then an equipment characteristic analysis section 23 classifies the characteristic of the connection of the constitution equipments or the like and the analysis result by an effect range analysis section 22 is stored in a memory in the inside. Moreover, a diagnostic rule generating section 55 generates a diagnostic rule 46 and stores it in a diagnostic rule file 29. Thus, the constitution of a network 33 is diagnosed preliminary and fault information 42 from a fault detection deciding section 31 is sent to a logic processing section 25 in such a manner, and then the fault diagnosis is implemented base on the information and the diagnostic rule 46 extracted from the diagnostic rule file 29.
