摘要
为传感网应用环境搭建一套感知分析系统,以降低虚警和漏警率是很有意义的。与传统仪器相比,虚拟仪器基于"软件就是仪器"的核心思想,具有易用性、用户可定制和二次开发性。本文设计了基于虚拟仪器的传感网研发测试平台,搭建了拟实感知研发系统。该系统解决了感知系统设计中的一体化硬件模拟和仿真问题,并且针对不同类型感知信号进行特征提取,提高了信号采集和感知的精度。
It is significant to build a perception and analysis system for a sensor network application environment, with the aim at reduc- ing false alarm rate and missing alarm rate. Compared with traditional instruments, virtual machine has the property of usability, cus- tomizability and potential exploitation, based on the core concept of ＂software is machine＂. This paper designs a sensor network devel- opment and test platform based on virtual instrument technology, and builds a virtual reality perception research and development sys- tem. The proposed system solved the problem of integrated hardware and modeling simulation in the perception system. Meanwhile, ac- cording to different types of signal, it performs the feature extraction and achieves high accuracy in both sampling and sensing.
