摘要
由光栅四倍频电路组成的测位移拉绳位移数字信息无线群测系统,在多台拉绳位移测试仪上装入无线模块,将其组成无线通讯网络,从而实现多点位移数字信息的采集及其远距离传输。实践证明,该系统稳定性好,受干扰小,信号传输准确且速度快。
Communication network in wireless measuring system oI grating 4-multiplier circuit is used lor transier of digital information of cord displacement from many points in a long distance. Practice shows that the system with communication network is stable, anti-interferenced and speeding.
