PURPOSE: To shorten calculation time by encoding only input data and output data and comparing encoded distinguishable results of two application microprocessors mutually in accordance with program. CONSTITUTION: Two microprocessors P1 , P2 arranged in parallel are provided, and input data DE by an input sensor CP is input in each of them through an analog/digital converter A/N1 . The results of processing R1, R2 of each microprocessor P1 , P2 are sent to a third comparison processor (voter) P3 , and the results of processing R1, R2 are compared by applying an encoding process means using a software in the voter P3 . When the results of comparison are satisfactory, a permission sign S symbolizing normal operation is sent to a dynamic controller CD to output digital data of function outputs Si, Sj to an actuator ACT through a digital/analog converter N/A. |
