基于无线传感器网络技术的收视率调查系统

通过对收视率调查方法的比较和学习，提出一种基于无线传感器网络的收视率调查系统，通过无线传感器节点将调查对象的特征参数提取，并对特征参数进行数据融合和压缩处理，然后通过汇聚节点将数据通过以太网传输到后台服务系统。利用一个辅助的系统和后台服务系统相结合来提供调查样本的自然和社会属性，使得调查数据更全面。整个系统在调查过程中对用户没有任何影响，并且无需占用用户的电话线或者使用IC卡来收集信息。该系统能够实时有效地对调查样本进行调查，并对调查样本不产生任何的影响，保证了调查数据的客观性和系统的非入侵性。

An Audience Rating Investigation System Based on Wireless Sensor Networks

After the comparison of several methods used in audience rating investigation system,the paper proposes an audience rating investigation system based on wireless sensor networks.By using wireless sensor nodes,the characteristic parameter can be collected,syncretized,compressed and be transmitted to the background service system through Ethernet.The proposed system will jointly use an assistant system and the background service system to provide the natural and social attributes of the objects.The whole system can efficiently avoid the interruption to the audiences.And all data can be collected without using IC cards or the audiences' telephone line.So the system can make the result of investigation friendly and objective.
