Abstract

PURPOSE:To perform accident analysis requiring a high resolution, by adding a timing circuit and a shift register to the analogue input device and by performing the function of the accident data gathering program in hardware manner. CONSTITUTION:The plant state analogue signal is converted to a digital signal by A/D converter 1; and if the timing signal is output from shift timing circuit 8, data read before is transferred to shift register 7b, and new A/D-converted data is applied to shift register 7a. Thus, time series data is formed on n sets of hardware shift registers 7, and data following the n-th data are abandoned. Though data freezing timing decision is performed by accident deciding program 9, shift timing circuit 8 stops generation of the shift timing signal by the programmable shift stop instruction. Meanwhile, contents of shift registers 7a-7n are read out by accident analyzing program 10.
