Bridge Remote Management System Based On Wireless Network Design Study

Regarding the actual production project of Xiamen Haitian Port Container Company——crane remote monitoring management system, the thesis researches the design and implementation of Haitian crane Remote Monitoring and Management System. The operation of this program has been put into production and achieved initial results.The full text of the overall bridge consists of two modules : Remote Monitoring System Monitoring and Monitoring Management System, In which Remote Monitoring System is the focus of the article. It gives a comprehensive analysis of the the whole process of system design .Remote Monitoring System building program based on the Haitian situation investigation, it selected "data acquisition -->RCMS+ local wireless transmission equipment Guangzhou Trade Fair", The first acquisition of equipment to local information through wireless LAN transmission to the distal RCMS Server erected directly in the distal generate human-machine interface, so as to realize the remote monitoring equipment. Ethernet communication for data acquisition program selected real-time control of data transmission, CI545 communication board for the use of the communications functions and the communications between PC and PLC. AC410 RCMS lies in the installation of the computer-driven, AC410 PLC Ethernet switches through real-time data acquisition. Communications and data transmission through the PC as a media server developed by AC410 OPC, achieved through standard interfaces of the real-time data acquisition. AC410-driven development the four parts of the main functions : IP packet interception, IP packet analysis, data cache and cache read interface; The development of AC410 OPC server chooses Microsoft Visual C++6.0 as the basic language. For the standard interfaces part, it selects the ATL application procedures guide for the development of COM components program, and for the hardware communications part, it uses Microsoft Visual C++, the object-oriented programming way for the bottom communications procedures and the basic interface. Choosing Cisco Aironet 2.4GHz data transmission network covering the entire program, with the stability, scalability, data confidentiality, mature durable and convenient management advantages. In remote monitoring system configuration, software configuration selection of interactive human-machine interface. Design and Implementation of the system, including equipment condition monitoring, maintenance of early warning systems, diagnostic systems maintenance history, / modular programming system, the Statistics and Reporting System, there Rubber Tired Gantry Crane GPS positioning system (Alternative). CCTV Surveillance (CCTV) system (Alternative) Remote Monitoring System subsystem of the bridge.The monitoring system and management system, integrating the introduction of the MES (Manufacturing Execution System) concept. It shielding layers of the differences between the management and control system, the eventual realization of a real-time integrated data exchange platform Through data interface and data acquisition, data archiving and storage. Configuration data and the application of data and database management to achieve the organic integration of the management and control layer.Port site for the full text of research data accessible, real-time, highly efficient transmission and sharing, and port control management platform will be of practical significance, and it is the automation and informationization organic integration, management and control as well as a high degree of unity in thinking, the development of port efficiency and information necessary choice.
