摘　　要：基于正交分解的网络大数据信息处理平台采用单一网络数据特征提取方法,导致数据信息处理效果较差。故设计基于Web的网络大数据信息处理平台。设计平台体系架构包括服务层、功能层和平台层。采用以太网管制芯片CP2200和单片机C8051F340构建网络大数据信息采集模块,平台层通过该模块进行网络大数据信息的采集,利用以IXP2400网络处理器为核心的网络大数据信息处理器实现对网络大数据的信息处理。功能层采用时域特征提取算法对网络大数据中人为数据瞬时能量及其均方值、过零率和高过零帧比特征进行提取,利用频域特征提取算法对人为数据内的梅尔频率倒谱系数及线性预测系数进行提取,为后续信息处理提供可靠分析依据。试验结果表明,所设计平台进行网络大数据信息处理时稳定性高、资源占用率低、运行效果好。Since the network big data information processing platform based on orthogonal decomposition adopts a single network data feature extraction method,which may result in poor effect of data information processing,a network big data infor-mation processing platform based on Web is designed.The system architecture of the designed platform is composed of the ser-vice layer,function layer and platform layer.The network big data information acquisition module is constructed by using the Ethernet control chip CP2200 and the microcontroller C8051F340.In the platform layer,the network big data information is col-lected by the network big data information acquisition module.The network big data information processor taking the network pro-cessor IXP2400 as its core is used to realize information processing of network big data.In the function layer,the time domain feature extraction algorithm is used to extract the artificial data instantaneous energy,and its mean square value,zero-crossing rate and high zero-crossing frame ratio in network big data.The frequency domain feature extraction algorithm is used to extract the Mel-frequency cepstral coefficient and linear prediction coefficient in the artificial data,so as to provide a reliable analysis basis for the follow-up information processing.The test results show that the designed platform for network big data information processing has high stability,low resource occupancy rate and good operation effect.
