DEVICE FOR CONFLICT DETECTION IN LOCAL COMPUTER NETWORK Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device is provided with half-wave rectifier 3, comparator 5, delay elements 6 and 7, AND gates 8-10, d flip-flops 11, 12, counters 13, 14, code-to-voltage converters 15, 16, comparison circuit 17, one-shot multivibrator 18, register 19, first OR gate 20, second OR gate 21. When adding signals coming from one or more subscribers in multidrop line, conflicts can be detected both by increase in total signal and by its decrease, depending on time position of signal addend pulses. Automatic control of comparator threshold levels provides for adapting to signal levels in multidrop line. EFFECT: improved reliability of conflict detection in local computer network. 2 dwg
