【摘要】：激光投线仪能提供水平线和铅垂线基准,适用于泵站建设中建筑物与机电设备安装的基准标定.为解决传统激光投线仪光线校准精度较低、调节速度慢、人为因素影响较大等问题,在对现有激光投线仪光线调校原理深入研究的基础上,提出了一种新型激光投线仪光线调节系统.首先,设计了一套光线调节平台,该平台采用伺服电动机驱动光线调节螺栓,调节光线的水平度和垂直度,并通过线阵电荷耦合元件(charge-coupled device,CCD)检测激光线的水平度与垂直度来实现设备的校准;其次,基于模糊"比例-积分-微分"(proportion integration differentiation,PID)控制方法设计了用于实现光线自动调节的闭环控制系统.试验测试结果表明,所设计的光线调节平台调节过程平缓,速度快,水平度与垂直度都能控制在±1 mm范围内,满足出厂要求.
[Abstract]:Laser wire-throwing instrument can provide horizontal line and lead vertical line datum, which can be used to calibrate the installation of building and electromechanical equipment in pumping station. In order to solve the problems such as low precision of ray calibration, slow adjusting speed and great influence of human factors, the principle of ray calibration of the traditional laser line thrower is deeply studied. In this paper, a new type of light adjusting system for laser wire threading instrument is proposed. First of all, a light adjusting platform is designed. The platform uses servo motor to drive the light adjusting bolt to adjust the level and perpendicularity of the light. The calibration of the device is realized by detecting the flatness and perpendicularity of the laser line by the linear charge coupled element (charge-coupled device,CCD). Secondly, A closed loop control system for automatic light regulation is designed based on the fuzzy "proportional-integral-differential" (proportion integration differentiation,PID) control method. The test results show that the adjustment process of the designed light adjusting platform is smooth and fast, and the flatness and perpendicularity can be controlled in the range of 卤1 mm, which can meet the requirements of the factory.
