（毕业设计论文）《PLC在舞台吊杆中的应用》.doc

PAGE 摘 要 随着人们生活水平的提高，对舞台设计和背景提高了更高的要求。舞台吊杆以其多功能和高利用率在众多演出场馆和剧场中得到普遍应用。本系统将工业级控制器PLC和高精度位置检测传感器应用舞台吊杆控制系统，实现吊杆自动正确定位控制。 本论文首先介绍了舞台控制系统与PLC技术的发展状况。第二章介绍了控制系统的整体设计方案及主要器件绝对旋转编码器、PLC和变频器的选择，并对所选器件做了必要的说明。第三章介绍了控制系统各个子模块的实现电路，包括配电部分的设计、变频器外围电路及变频器控制下的6个吊杆调速系统设计、电动定位吊杆控制系统设计和PLC与触摸屏的连接。第四章介绍了控制系统的软件设计，包括格雷码到二进制的转换、调速系统的软件设计及电动定位控制系统的设计。最后，对所做的一些工作进行了总结，并对舞台吊杆控制系统进行了展望。 关键字：PLC，舞台吊杆，控制系统，绝对旋转编码器，变频器 ABSTRACT Along with people life level of exaltation, stage setting exaltation higher of the people requesting. The platform boom which it has multi-function get in numerously the performance the field building and theater with high utilization widespread application. The system will be applicated to the application platform booms control system with the industrial grade PLC and high precision position detection, Suspenders automatically achieve the correct positioning to control. The paper introduced condition of platform control system and the PLC technical development first. The chapter 2 describes the overall control system design and key devices absolute rotary encoder ,PLC and Inverter， and explained to which chosen the spares to be a necessity. The chapter 3 introduced realization which each control system mold , include the designed of which the electricity part ， the inverter and under the Inverter controlled of 6 booms control system designed, and designed dynamoelectric booms which fixed position control system, the PLC connected with the touch hold . The chapter 4 introduced software designed of control system, include the conversion of the gray code and the software which adjusted speed booms designed of control system ,the software designed of the dynamoelectric booms which fixed position .The last, made to a summary to some works ,and made prospect to the platform booms control system. Key words: PLC，platform boom, control system, the absolute encoder, Inverter 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc169256270 摘 要 PAGEREF _Toc169256270
