【摘要】 本文针对传统提升系统在工业应用中的局限性,介绍了永磁直线同步电动机提升系统的优点及其研究与发展情况。首先从直线电机提升系统所采用的驱动电机——永磁直线同步电动机的基本结构、分类、工作原理及特点等方面进行介绍,进而对提升系统的结构、工作流程进行分析。针对本文的研究对象,一台永磁直线同步电动机提升系统的实验模型,设计控制系统总体方案,选择采用工业控制计算机与PLC的两级控制系统,介绍了系统中所使用的主要器件。然后针对控制系统的各个子单元如电源电路、电机控制电路、PLC系统、变频器控制电路、数据采集电路、通讯接口等完成硬件设计,并结合提升系统的运行环境讨论了现场所应用的抗干扰措施。提升系统运行时由PLC在线产生加速度为梯形的速度给定曲线,采用速度PID闭环控制算法对提升系统进行调速。PLC梯形图程序的编写采用模块化编程思想,将提升系统程序根据功能划分,并较为详细地介绍各功能子程序的设计。上位机软件的开发采用Visual Basic 6.0集成开发环境,既满足了提升系统数据采集及监控的需要,又具有良好的人机界面环境。更多还原

【Abstract】 Paper introduces that tradition hoisting system has some limitations in industry application. Because of the drawback of the traditional hoisting system, the article introduces the PMLSM hoisting system and its research and development. First, paper introduce the driven machine of linear motor hoisting system, the basic structure, classification, working principle, characteristics, etc. Then talk about the structure of hoisting system, work flow analysis. In this study, the research object which we researched is a permanent magnet linear synchronous motor hoisting system experiment model. Design the overall plan of the control systems, selected industrial PC and PLC as control system main frame, introduced the critical system device, and the introduced the various sub-systems such as power supply circuit modules, motor control circuits, PLC subsystem, inverter control circuit, data acquisition subsystem, communication interface circuit. The study also takes working environment into account, discussed interference protection measure. The preset velocity is used a ladder accelerate curve, it produced by PLC online calculation, used close loop PID algorithm archive velocity adjust of the hoisting system. And also the paper introduces the PLC program using modular method, and then various parts of the design. Computer supervisory software is designed and programmed using Visual Basic 6.0 integration design environment, it meets the demand of data acquisition and supervisory, and also have a good man-machine interface.更多还原
