一种多通道无线静态应变测量装置

摘要

针对传统应变测量装置监测数据时与主机之间布线不够灵活、数据监测方式单一等问题,设计了一种多通道无线静态应变测量系统.运用无线通信技术和自容式存储技术,将离线监测与在线观测功能相统一,可以高精度、大容量、多通道、全程智能化地进行应变数据采集与传输.实验证明:系统工作稳定、数据传输可靠,能够对各通道节点进行状态监控、参数设置和数据回传等操作.%According to the problem that the wiring between the customary strain measuring device and the host are not flexi-ble enough and ways of data monitoring are onefold,a multi-channel wireless strain measurement system was implemented,which integrated use of wireless communication technology and self-contained storage technology,combining two functions of on-line ob-servation and off-line monitoring,it can offer high precision,large capacity,multi-channel,intelligent strain data acquisition and transmission.Experimental results show that the system is stable,reliable in data transmission,which carries out state monitoring, parameter setting and data return operation of each channel node successfully.
