摘要
综合考虑商用串口卡串口种类少、数量少、可靠性低以及不可定制等问题,研究一种具备CRC校验和接口保护功能的20通道多种类串口卡。通过CPCI总线与芯片的通信转出串口信号,用CRC校验算法确定数据传输的正确性,同时设计接口保护电路。仿真和实验证明了该串口卡的可行性和电路的有效性。
To address the problem that few channel and access, low reliability and non-customized in series communication card, twenty channels multi-access series communication card based on CRC checkout algorithm and interface protection technique is studied. Series signal from communication of CPCI bus and chips is used to checkout validity of CRC checkout while the interface protection circuit is used to protect the series card. Simulation and experiment demonstrate the feasibility of the series card and the effectiveness of the electro-circuit.
