Fourthly , a dynamic property tester used to impact structure , which has multi - parameters testing function , and a health monitoring signal conditioner and amplifier were developed , and experimental system applied to monitor structural health was established 第四,研制完成用于材料冲击试验的多参数动态性能试验机和健康监测微弱信号调理与放大仪,完成了结构健康监测的实验系统。
By using wavelet transform , the monitoring signals of bridge structural health monitoring are described on different scales . by simply processing the monitoring date in bridge health monitoring system , we can obtain the features of bridge structure 利用小波分析理论,对大型桥梁结构健康监测信号进行多尺度分解,不需要复杂的算法,只是对采集的数据进行深加工,即可表达出多尺度上的特征。
Evaluation and assessment performances of av system and equipment programming by maintain equipment services and tuner tv sets and monitors signal strength of distribution system periodically of the related tasks and works , be keep well informed and follow - up function and related activity 通过定期检测电视机协调器及卫星信号的强度分布体系等工作来评估av系统和设备的运行情况,并跟进和时刻了解相关情况。
The software of the device is developed using delphi 5 . 0 environment , which can control the data acquisition , monitor signals and show the real - time waveform . the software start recording data in fault and calculate the fault site then , which has built database and make the device a rounded system 采用delphi5 . 0环境编程,完成工控机对数据采集卡的控制,实时监测、显示电压电流波形,故障时启动录波,进行故障测距,建立了故障数据库,使测距装置成为一个完整系统。
Under the interface of windows , using technology of visual c + + and multi - thread concurrent tcp server ( client / server architecture ) , the monitored signals of rotary machine have been shared in local area network ( lan ) , and the requirement of distributed monitoring and diagnosis system ( dmds ) has been realized 本系统在windows界面下,运用visualc + +中的winsock技术,采用多线程并发tcp服务器结构模式(客户机/服务器模式) ,实现了局域网内旋转机械振动信号的共享,达到了分布式诊断模式( dmds )的设计要求。
