Abstract
PURPOSE:To enable the maintenance and inspection and to improve the reliability of a double circuit, by means of setting up a monitoring part which detects the damage of an analogue part by comparing the output of the analogue part always, in addition to a judging part which detects the abnormalness of the input to the analogue part. CONSTITUTION:Outputs V1, V2 of analogue parts 1, 2 are respectively connected to a judging part 3 which detects the abnormalness of their inputs, and to an always monitoring part 4, and synthetic output V3 is connected to a wind comparator COM, for example, of the circuit of a by means of connecting the outputs V1, V2 to resistances R1, R2 respectively in the always monitoring part 4. And when the analogue parts 1, 2 are in normal state, the synthetic output V3 becomes to zero for example, the wind comparator COM is subjected to show the prescribed output. By such means, the work efficiency of the maintenance and inspection is improved by monitoring the analogue parts 1, 2, and the reliability of the double circuit is improved and enables the operational inspection of the analogue parts 1, 2 at the same time.
