Transformer Oil Chromatographic Data Transmission Method Based on OFDM Carrier Communication Technology

由于常规的变压器油色谱数据传输方法未进行编码处理导致传输效果不佳,文章设计一种基于正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)载波通信技术的变压器油色谱数据传输方法。利用色谱分析仪获取数据,进行归一化处理和特征提取,以获取数据的关键信息,并对其进行编码。计算数据的覆盖范围,并根据覆盖情况制定合适的传输协议。在OFDM支持下评估信道质量,根据信道状况分配子载波,动态调整分配结果,计算传输频率,实现高效的数据传输。实验结果表明,该方法误码率低,传输效果较好。

Because the conventional transmission method of transformer oil chromatogram data is not coded,the transmission effect is poor,this paper designs a transmission method of transformer oil chromatogram data based on Orthogonal Frequency Division Multiplexing(OFDM)carrier communication technology.The chromatographic analyzer is used to obtain the data,normalize and extract the features,so as to obtain the key information of the data and encode it.Calculate the coverage of the data,and formulate the appropriate transmission protocol according to the coverage.Under the support of OFDM,the channel quality is evaluated,subcarriers are allocated according to the channel conditions,the allocation results are dynamically adjusted,and the transmission frequency is calculated to achieve efficient data transmission.Experimental results show that this method has low bit error rate and good transmission effect.
