A device for detection and correction of errors in the clinical for transmission bus in parallel hydroxyacetals corresponding triple

摘要

The device comprises three selectors or "voters" 1, 2, 3 connected respectively to buses I1, I2, I3 and designed for determining the data item to be reproduced on buses S1, S2, S3 respectively. In order to do this each selector is further connected to an input bus of one of the other two selectors and to the output bus of the other of these two selectors. The assembly I1, I2, I3 constitutes the triplicated redundant bus to be monitored. Internal status buses B12, B13 and B23 allow the selectors to exchange the results of comparisons of the data on the input buses and on the external output bus to which they are connected in order to determine that one of the input buses whose data item will be transferred to the output bus attached to the selector. Application to a bidirectional triplicated redundant bus. IMAGE
