摘要：利用无线传感器节点实现了一个无线声学传感器网络，该网络中的传感器节点配备麦克风电容器，用于捕获家禽的声音数据，并通过网络将其传输到采集点。高性能计算机可以处理这些大量的动物不同行为下的音频信号。通过数据信号处理和音频信号分析，可以获得家禽的声音，然后将其转化为相应的行为模式进行福利评估。在压缩感知算法的基础上，兼顾压缩比带来的功耗节省和计算成本之间的平衡，设计了一种低功耗、低成本的传感器节点作为家禽声学数据采集和传输的基本单元。然后，基于Zigbee的无线声学传感器网络，以满足短的传输距离和有限的存储和能量资源的挑战。实验结果表明，压缩感知算法能够提高无线声传感器网络的通信性能，具有高可靠性、低丢包率和低能耗的特点。

Abstract: A wireless acoustic sensor network was realized using wireless sensor nodes equipped with microphone condensers, in which its sensor nodes were configured to capture poultry sound data and transmit it via the network to a collection point. A high performance computer can process these large volumes of animal audio signals under different behaviors. By performing data signal processing and analyzing the audio signal, poultry sound can be achieved and then transformed into their corresponding behavioral modes for welfare assessment. In this study, compressive sensing algorithm was developed in consideration of the balance between the power saving from compression ratio and the computational cost, and a low power consumption as well as an inexpensive sensor node was designed as the elementary unit of poultry acoustic data collecting and transmission. Then, a Zigbee-based wireless acoustic sensor network was developed to meet the challenges of short transmission range and limited resources of storage and energy. Experimental results demonstrate that the compressive sensing algorithm can improve the communication performances of the wireless acoustic sensor network with high reliability, low packet loss rate and low energy consumption.
