Other AbstractThe invention relates to a safety-instrument data processing diagnosis circuit and method based on a microcontroller redundancy technology and specifically relates to a design circuit of a double-processor serial control framework in an intelligent safety instrument transmitter of an industrial control system. In terms of function, the double-processor serial framework realizes simulation quantity data acquisition processing and HART communication processing and at the same time compares processing data so as to realize mutual diagnosis and find out errors of processing results, resulted from data errors and thus error signals are prevented from being output and operation safety of a system is ensured. The design has the characteristics of being high in practicality, wide in applicable scope, low in cost and great in diagnosis effect and the like.
