Research on Wireless Audio Sensor Networks Data Compression Method Based on Compressive Sensing
摘要
Abstract
Acoustic signal acquisition and monitoring system of stored grain pests based on wireless sensor networks has become a trend in a large-scale granary .However , due to the restrictions of the wireless network bandwidth resources and acquisition node hardware resources the existing wireless acoustic signal acquisition and monitoring system of stored grain pests can hardly achieve multi-point distributed acquisition and real-time reliable transmission of large flow of acoustic signal .For this problem , an acoustic signal acquisition scheme based on compressive sensing had been proposed in this paper , which not only can achieve the calculation and transmission of pests acoustic signal characteristic parameters but also can achieve real-time monitoring of the granary by collecting multi-point and real-time complete pests acoustic sig-nal .The experimental results show that:the proposed method is reasonable and feasible .In the circumstances that signal error is less than 0 .5%in the client side , by using the proposed method multi-point distributed acquisition and real-time reliable transmission of the acoustic signal had been achieved effectively .关键词
