Abstract
To fulfill requirements for monitoring aged people,this paper proposed a platform design for monitoring based on smart phone microphone sensor network.The platform utilized smart devices equipped with microphones to collect audio signals,adopted Wi-Fi as the infrastructure network,supporting upper layer protocol MQTF to transmit data and directives,and introduced one acoustic geometrical location algorithm based on energy ratio as the core function of this monitoring system.Firstly,a MATLAB simulation experiment confirmed the rationality of the principle and feasibility of the algorithm.Secondly,it performed a microphone feature test on four heterogeneous Android devices thus lead to parameter amendment.Finally,it built a test platform and experiment on it achieved usable precision for monitoring.关键词
