摘要
为实现电子经纬仪的自动化操作和轴系的自动转动,以缩短操作时间、提高测量精度为检验标准,设计了轴系电机伺服驱动系统。从电子经纬仪整体技术性能指标出发,采用硬件及配套软件相结合的研究方法,通过轨迹规划完成定位控制,对整个照准系统的设计进行了完善。以实例对系统的可操作性和测量精度进行了检验,实验结果表明:定位控制实验中,位置跟踪误差精度约为0.01°,平均误差控制在3″以内,且运行时间较短。该系统满足了经纬仪对轴系控制的设计要求,同时也为电机精确定位控制研究提供了思路。
In order to realize the automatic operation and the axis＇ automatic rotation of the electronic theodolite, this article has designed of the servo drive system for theodolite＇s axis. The testing standards are to reduce the time of operation and improve the measurement accuracy. According to the integrated technical performance standard of the electronic theodolite, the research method, which combines of the hardware and supporting software, is taken. The positioning control is completed by the locus planning and the design of the entire collimation system is improved. An experiment is designed and conducted, in which the system＇s operability and accuracy is determined. In the positioning control experiment, the position tracking error is about 0.01°, the average error is 3″or less, and the working time is short. It meets the requirements of the axis＇ automatic control, and also gives references for researching on the precise positioning control of the motor.
