| 摘要: |
| 电子式电流互感器(ECT)可极大地提高测量可靠性和精度。ECT的高压侧采样数据经过光纤传输至低压侧,可采用循环冗余校验(CRC)来确保数据传输的质量。在比较串、并行处理算法性能的基础上,利用VHDL语言设计了快速并行处理算法,构建了一个CRC模块,并采用仿真软件ModelSimSE验证此模块。通过对实例的时序仿真波形分析,证实了此CRC发生器可得到准确的编码输出。 |

| Abstract: |
| ECT(Electric Current Transformer) may improve the measuring precise and stability. While the signals sampled at its high - voltage side should be transferred to its low - voltage side via fiber. CRC is used to ensure the quality of data transmission. Based on the performance comparison between serial and parallel processing algorithms,a CRC module with fast parallel processing arithmetic is built up,which is designed by VHDL and verified by ModelSim SE. Simulation results show that the CRC module generates correct code outputs. |
