摘要
论文中,首先就物体提升平移技术的国内外发展水平进行了剖析、专研,而后给出了一种使用电磁阀 PLC 组态软件设计的控制系统。继而介绍了各种控制算法,对PID控制算法的选择作为控制系统的要求,并对数学模型的机械部分和电气组合,在Webaccess组态软件平台上搭建了模型。外设系统包含液压系统、电液比例阀、PLC控制箱、电脑、传感器等模块;软件包括上位机人机界面、PLC控制软件两大部分,PLC控制软件采用腾空专用编程软件Multiprog编制了梯形图控制程序,计算机专用的人机界面( HMI )利用组态软件WebAccess7.0作为发展平台,并且阐述了通讯模块,硬件和软件的通信方式和协议。最后,对于本项目中的不足之处,提出了需要改进的方向。
物体顶升平移技术作因其具有经济实惠、施工快速等特点,已广泛的应用在国内外物体改造工程中,是一个很有前途的新技术。不过正常的顶升技术没法确保提升准确度和稳定性,并且步骤复杂、容影响工作效率、容易延误工程时间,容易发生安全隐患。针对这种状况,在现有系统的优缺点分析,基于改造工程,在现代理论和技术的基础上,根据相关理论和算法,开发了一个系统的设计方案。

Abstract
Building jack-up translation technology because of its economical and practical, quick construction, etc, have been at home and abroad has been widely used in building, is a new technology has wide application prospect. But normal jack-up technique can"t ensure the jack-up accuracy and stability, and workload big, affect work efficiency, easy to delay the timing of the project, prone to safe hidden trouble. Aiming at this situation, analysis on the advantages and disadvantages in the existing system, based on the reconstruction project, based on the modern theory and technology, combining the theory of synchronous jack-up and control algorithm, developed a system design scheme.
In the paper, the beginning is building jack-up translation technique analyzes the level of development at home and abroad, study, and then presents a use of electromagnetic valve PLC configuration software design of control system. Then all kinds of control algorithm is introduced, the selection of PID control algorithm as the requirement of control system, and the mathematical model of mechanical part and electric combination, on Webaccess configuration software platform to build the model for simulation of control system. The study of hardware and software design , the electro-hydraulic proportional valve, PLC control box, computer and sensor module; Software including PC man-machine interface, PLC control software of two parts, the PLC control software adopts special formulation of the ladder diagram programming software Multiprog suspension control program, the computer dedicated human machine interface (HMI) using the configuration software WebAccess7.0 as a development platform, and details the PLC and communication module, communication mode and communication protocol of WebAccess..
Finally, for the project of the shortcomings, puts forward the direction of the need to improve.
