MONITORING DEVICE Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: expected predetermined information to be generated by monitored devices while they are running is compared with values generated directly in the course of operation. Noncoincidence of expected and generated values indicates fault. Monitor has two flip-flops, two AND gates, four OR gates, three registers, two counters, pulse shaper, two NAND gates and storage unit. Monitor makes it possible to extend class of detected errors arising during data exchange between data source and processing device due to time control of cycles and driven tops of graph-scheme of information algorithm and reduced time taken to detect error in exchange. EFFECT: improved validity of monitoring results. 3 dwg, 5 tbl
