一、概 述 垂线坐标仅及引张线仪是用于水电站大坝、船闸等建筑物水平位移和挠度测量的监测仪器,与正垂线、倒垂线及引张线配套使用。本所根据葛洲坝水利枢纽安全检测自动化和三峡大坝安全监测自动化试验研究的需要,吸取了国内外同类仪器的运行经验教训,于1993年9月至1994年8月完成了STC-50型步进电机式遥测坐标仪和SWT-50型步进电机式遥测引张线仪的研制工作。于1994年10月在葛洲坝水利枢纽二江泄水闸
First, an overview of vertical coordinates and only lead line instrument is used in hydropower dams, locks and other buildings horizontal displacement and deflection measurement of the monitoring equipment, and the vertical, inverted vertical line and supporting the use of the line. Based on the requirements of automation testing of Gezhouba Hydro-junction Safety Monitoring and Safety Monitoring of the Three Gorges Dam and learning from the operation experience of similar instruments at home and abroad, the Institute completed the STC-50 type stepping from September 1993 to August 1994 Motor Telemetry Coordinate and SWT-50 stepper motor telemetering the development of a line instrument. In 1994 October in Gezhouba Dam two rivers sluice
