【摘要】:港口对经济所带来的集聚效应一直以来都十分明显,它在现代物流中的占据着重要地位。随着经济的不断发展,货流量也在不断提升,业务的迅猛增长对现代港口的发展也提出新的需求,随着信息化发展的软硬件技术的日趋成熟,港口的信息化建设俨然成为了当前的首要任务。近年来,嵌入式技术及其应用的产品在飞速地发展,并且已经广泛涉及工业、制造业以及我们生活方方面面。嵌入式技术及其产品以其系统的稳定性、功能的专用性及环境的良好适应性,能够在工业领域充分发挥其突出的优势。以港口信息化建设的主线,本文旨在基于嵌入式的技术实现港区各起重机械的信息化,从而提高港口整体作业流程的效率及安全性。针对港区常见的多门机协同作业的工作情况,本文致力于研究一套全面的监控设计方案,以解决多门机作业时可能出现的“打架”现象,从而更大程度的解决人为因素在作业中的不确定性问题,主要的研究内容如下:综合分析多门机协同作业下的工况及系统开发与业务流程的需求,本文首先提出系统的硬件架构及软件设计框架,从而搭建一个以远程监控模块、前端显示模块和数据采集及处理模块为基础的多层次的港区监控网络。本文选定四连杆组合臂架式的门座起重机作为主要的研究对象,对门机运动过程中臂架系统的变换进行分析并建立其动态运动方程,再结合当前在三维空间的干涉检验原理,提出针对关键点的多门机作业干涉问题的检验流程。针对系统的软硬件环境,本设计方案以ARM7及Cortex-A8分别为信号采集模块和前端人机交互系统的核心芯片并确定了各主要硬件的选型,接着重点阐述了应用系统开发的软件环境的搭建过程。系统的界面应用程序采用Qt/Embedded技术实现,运用宿主机与目标机联合开发的模式。界面应用程序结合门机作业系统的业务流程分析,基于司机模式及管理员模式分别开发出针对角色权限的操作界面,从而实现良好的人机交互,提升系统的作业及管理的效率。
[Abstract]:The agglomeration effect of port on economy has always been very obvious, and it occupies an important position in modern logistics. With the continuous development of the economy, the flow of goods is also rising, the rapid growth of business also puts forward new requirements for the development of modern ports. With the development of information technology, the software and hardware technology is maturing day by day. The information construction of the port has become the primary task at present. In recent years, the products of embedded technology and its applications are developing rapidly, and have been widely involved in industry, manufacturing and all aspects of our lives. Embedded technology and its products can give full play to their outstanding advantages in the industrial field because of the stability of the system, the specificity of the function and the good adaptability of the environment. Based on the main line of port information construction, this paper aims to realize the informatization of lifting machinery in port area based on embedded technology, so as to improve the efficiency and safety of port operation process as a whole. In view of the common co-operation of multi-door aircraft in Hong Kong, this paper focuses on a set of comprehensive monitoring and design schemes to solve the "fighting" phenomenon that may occur in multi-door operation. In order to solve the uncertainty problem of man-made factors in operation to a greater extent, the main research contents are as follows: comprehensive analysis of operating conditions under multi-door machine cooperation and the requirements of system development and business process, In this paper, the hardware architecture and software design framework of the system are proposed firstly, so as to build a multi-level port monitoring network based on remote monitoring module, front-end display module and data acquisition and processing module. In this paper, the four-bar combination gantry crane is selected as the main research object, and the transformation of the jib system in the movement process of the gantry crane is analyzed and its dynamic motion equation is established, and then the interference checking principle in the three-dimensional space is combined with the analysis. In this paper, the checking flow of interference problem of multi-door machine based on key points is put forward. In view of the hardware and software environment of the system, ARM7 and Cortex-A8 are used as the core chips of the signal acquisition module and the front-end human-computer interaction system respectively, and the selection of the main hardware is determined. Then, the construction process of the software environment for the application system development is described in detail. The interface application program of the system is realized by Qt/Embedded technology, and the mode of co-development between host computer and target machine is used. The interface application program combined with the business process analysis of the door machine operating system, based on the driver mode and the manager mode, respectively developed the user interface for the role authority, thus realizing the good human-computer interaction, and improving the efficiency of the system's operation and management.
