摘要
针对目前部分地震和震动监测仪器布设地点环境噪声大,需依靠无线网络上网,且数据需分别存储在监测终端和服务器端的现状,结合目前流行的Android便携式设备,在利用自适应滤波方法从背景噪声中提取信号的基础上,提出存储独立,适时无线传输的震动数据监测系统框架,解决面向传统C服务器,Android客户端基于二进制数组通讯延时和粘包问题。实验结果表明,该系统可以正确识别报警信号,完成对微震事件实时监测,图像下载和数据管理功能。
Seismic and vibrative monitors currently are deployed in noise environment. The vibrative data are collected in monitor terminal and server separately, and are transmitted by wireless network. Using protable Android device, a data monitor framework based on self-adapting noise cancellation filter is developed for storing and transmitting data independently at the appropriate time. This framework puts forward solutions for data adhering in communication using binary bytes and the delay of warning signals transmitted from C server. The experimental results show that this system can identify warning signal to monitor microquake correctly, download warning picture and manage warning data.
