Title:
DIAGNOSTIC DEVICE OF PLANT
Document Type and Number:
Japanese Patent JPS58175011
Kind Code:
A
Abstract:
PURPOSE:To decrease the burden of the CCT forming personnel, by inputting signals relating to a filter among signals given to an operation processor via the operation processor simulating the delay characteristics of a filter. CONSTITUTION:Data not related to the filter among data Xi quantized at a data logger 1 are transmitted to an operation processor 2 as an input. A signal relating to the filter is transmitted to an operation processor 3 simulating the delay characteristics of the filter and this output is transmitted to the operation processor 2. The processor 3 simulates the delay characteristics and processes the operation as shown in the following formula for example; Yi=Yi+DELTAt/T(Xi- Yi), where DELTAt is a time interval, T is time constant of delay, and j is time step. As a result, the output Yi of the operating device having the delay characteristics is transmitted to the processor 2 in place of the plant data Xi.
