摘要
基于ZigBee的SF6气体微水含量在线监测装置由处理器、数据采集和调理装置、ZigBee无线网络通信技术、报警控制装置以及电源电路组成。本装置通过监测SF6气体的湿度、温度、压力等相关数据信息,采用无线信息融合技术降低了测量误差,实现了测量系统自动定标、测量数据的补偿和确定输出报警信号,提高了测量的精度和可信度,延长了使用寿命。
on-line monitoring device for SF6 humidity based on ZigBee was composed of processors, signal conditioning units （SCU）, data-collection devices, ZigBee wireless network communication technology, control equipment of ventilation and alarm and powering circuits. Data information of humidity, temperature and pressure of SF6 gas can be monitored by the device. The application of information blending technique decreased the error of measuring, and achieved auto-calibration of measurement systems, compensation of measured data and signal output control, and improved precision of the reliability of measurement, and extended the service life.
