【摘要】 为满足对无间隙氧化锌避雷器(MOA)状态监测的需要,设计了MOA泄漏电流数据采集及传输系统。提出一种基于nRF905射频通信芯片的短距无线数据传输技术、GPRS远程数据传输技术和internet互联网数据传输技术的新方法。监测系统主要包括前端数据采集单元、nRF905无线数据传输单元、GPRS远程数据传输单元、应用ADSL互联网数据传输部分和远程监测中心。该监测系统集信号采集、通信、分析、计算、存储于一体,具备实时监测、波形显示、历史数据查询等功能。模块化设计,便于其它电气设备监测系统的扩展接入,对提高现有在线监测技术的应用水平起到了良好的促进作用。更多还原

【Abstract】 In order to meet the need of monitoring the gapless Metal Oxide Surge Arrester (MOA), the system of acquisition and transmitting data of leakage current is designed and a new way bases on the technology of wireless data transmission with short distance of nRF905 radio frequency communication ,GPRS data transmission with long distance and the internet data transmission is offered. The monitoring system includes the foreside data acquisition unit, nRF905 wireless data transmission unit, GPRS data transmission with long distance, application of ADSL data transmission and the monitoring system of monitoring central with long distance. It is an integration of data collection, communication, analysis, calculation and memory with the function of real-time supervisory, waveform display, historical data inquire. The modular design for the spread access of other electrical equipment monitoring systems has a promoting effect on monitoring technology on line.更多还原
