Reliable Data Transmission with Reduced Bit Error Rate

摘要

A data transmission system includes at least one transmission line. A sender is configured to send data frames to the at least one transmission line and a recipient is configured to receive the data frames from the at least one transmission line. The sender and the recipient are both configured to determine a check sum based on a plurality of corresponding data frames that are sent to and, respectively, received from the at least one transmission line. A check sum comparing unit is configured to receive and to compare the check sum determined by the sender and the corresponding check sum determined by the recipient. The check sum comparing unit is also configured to signal a transmission error or initiate a safety function when the check sums compared are not equal.

1. A system comprising:
a recipient configured to receive data frames from at least one transmission line, wherein the recipient is configured to determine a recipient check sum based on a plurality of corresponding data frames that are received from the at least one transmission line; a check sum comparing unit configured to receive and to compare the recipient check sum with a corresponding sender check sum determined by a sender transmitting the data frames received at the recipient and; a switch coupled to an output of the recipient and coupled to be activated upon receipt of a signal; and a safety circuit coupled to the check sum comparing unit, wherein the safety circuit is configured to transmit a deactivation signal configured to prevent the switch from conducting a ON current if the check sums compared are not equal.
