High reliabilitySdesign of controlSsignal transmission |
| |
| Abstract: | SIn the electronicScircuitSwe normally usedSor designed, they are more or less affected bySEMI. A small part of EMISisSdirectlySreceived by theSradio frequency radiationSmode,Smost of EMI is received by transient conduction. In the digital circuit,ScriticalSsignals such as reset,SinterruptSand control signal are most vulnerable toSEMI.SWhile we did EMI experiment in the developed equipment, the control signal was affected, causing instructionSsends error and affecting theSnormal operation of the equipment. In order to solve this problem,Swe first analyze the hardwareScircuit design, find theSproblemSand improvementSmethod; at the same time,Son the premise ofSnotSchangingSthe PCB board,Sthe control signals are blocked and eliminating tremble logic design about the control signal is improved. Finally,the high reliabilityStransmission of control signal are ensured by the hardware connection and logic design. |
