多门机协同作业相互干涉监控系统研究
[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.
