基于模糊神经网络的数字媒体数据自动化采集系统设计

为了改善数字媒体数据传输效果,确保系统安全、稳定运行,设计基于模糊神经网络的数字媒体数据自动化采集系统。构建数字媒体数据自动化采集系统框架,数据采集层利用数据采集卡获取不同渠道的数字媒体数据,由数据处理层的数据融合模块调用改进模糊神经网络算法完成数字媒体数据的融合处理后,通过数据传输层的分层自组织无线网络将其传输至存储应用层,实现数字媒体数据的存储、查询、显示与输出。实验结果表明:该系统采集的音频信号波形规律、曲线平滑、功率均值波动误差在(0,0.14),满足允许误差范围;数据传输效果优于采用DSR协议的单点传输方式,当数字媒体数据源为3时,平均峰值信噪比指标最高;具有数字媒体数据查询功能。

Research on the Innovativeness and Characteristic of Digital Media under the Environment of Internet and Big Data

In this paper, we conduct survey and research on the innovativeness and characteristic of digital media under the environment of Internet and big data. Under the background of the era of rapid change, the current education system is more severe impact and challenge. Creative industry is the product of cultural industry development to a new stage, is the most creative cultural industry and the origin of the core part of the new economic era of creativity industry is the condition of globalization. The research indicates that the combination of the big data with digital media is necessary and needed. In the future, we will test more related combination and creativeness.
