Research On Crane's Remote Wireless Realtime Monitoring Control System

The modern romate monitering control syetem is the combination of computer technology, network technology, communication technology, and control technology. It is the integration of communication technology and monitering control technology. With the development of computer network technology and romate control technology, it is the inevitable result to use network thchnology in romate monitering control syetem. Especially due to the development Internet, the study of romate monitering control syetem which is based on Internet thchnology is very importent. With the development of the port economy, people need much more lifting machine. And the port crane becomes more and more big, speed and automatic. The application of modern romate monitering control syetem can markedly improve the management status of port machine, and enhance the modernization level of port management.By plent of inquiry and study, and base on several projects, this paper sets up a romate monitering control syetem which is fit to the special situation of port and meets the actual requirement of port application. The main contents of the paper are as follows:1) It analyzes the development, control methods and model of the romate monitering control syetem. It also discusses the the integration of control network and the communication network in details. By comparing deffient kinds of control mothed and software structure, B/S—based romate monitering control syetem is choosed.2) It wholely analyzes the romate monitering control syetem, containing the analyzations of software syetem, control logic and the configuration of system's software and hardware, and establishes the local control system and network server system.3 )In order to realize dynamic data exchange and real-time communication, some methods to improve real-time capability of Web-based remote monitoring andcontrol system are analyzed and studied in this thesis o ASP.NET technology and OPC technology are discussed in detail.4) Use the 00 ideal to develop monitering control software, database system and OPC customer to realize the ruction of data acquisition, display and control. Construct the Web server to realize romate monitering control based on Internet.
