| Abstract: | To insure compatibility and inter-operability among the MVB equipment, it requires that the data transmitted in the bus need to be collected, and correctness and reliability of data transmission of the MVB network should be analyzed. According to the characteristic of the MVB protocol, this paper proposes an approach of analysis controller for MVB bus based on IEC61735 criterion. In the approach, it uses bit synchronization multi-point sampling algorithm to capture the data and then writes it to memorizer, ... |
