大量程步进式垂线坐标仪的研制

Development of a Large-scale Stepper Motor Driven Pendulum Telecoordinometer

步进式变形监测仪器具有长期测量、测值稳定、可靠性高、测试原理简单、适用范围广等优点,在中国的大坝安全监测领域得到了广泛应用,但大量程步进式变形监测仪器的研制很难。文中介绍了一种新型步进式垂线坐标仪,该垂线坐标仪在引入独特的结构设计、先进的电子测量技术和优化的电机驱动控制策略的基础上,很好地解决了大量程工况下的高精度测量问题。

Owing to the advantages of long term detection, high-stability, high-reliability and visualized working principle,stepper motor driven deformation monitoring instruments have been widely used in the field of dam safety monitoring in China. However, it is still difficult to develop a large-scale product. On the basis of advanced electronic measuring techniques and optimized motor driving and controlling strategies, a novel large-scale stepper motor driven pendulum telecoordinometer is developed, which ensures high precision in large scale measurement.
