The Realization Of Embedded Data Collection System Based On Ethernet

Network technology industrial development raises profound technological change control areas. Control systems and control system structures network system openness will be the control system technology development trends. In recent years, Ethernet and an embedded remote monitoring system of considerable development, is currently trying to use Ethernet openness towards an embedded control system network.As a new technology, an embedded Ethernet access Ethernet refers to an embedded system, the computer system can visit the plug-in conferencing equipment, and achieve long-range surveillance of an embedded system, control, diagnosis, testing and configuration, and other functions. Such as high-speed Ethernet technology in industrial distributed control site offers a convenient, fast and generic-strong, relatively low-cost control programme.In the first paper explained the concept of an embedded network remote monitoring system, introduced the system of history, research methodology and research significance of the development of a vision of the system.Communication agreement is the key to the realization of network communications. The second chapter in the use of a wide range of introduced several communications agreements, especially after the realization of the monitoring system needs TCP/IP agreement and the contents of a detailed exposition Taojiezi.Secondly, on an embedded operating system 16ug Clinux main function modules, and the practical application of 16ug Clinux in some aspects of the corresponding analysis;Then introduced the concept of transplantation, the main introduced an embedded operating system 16ug Clinux the transplant process, including translation environment creation, and reduction in hardware changes. 16ug Clinux documentation systems for the summary analysis.Then S3C444B0 from an embedded ARM7 controller with details on the computer interface, A/D data collection module on the basis of data collection applications in the operating system platform ucLinux transplant and driven development, completed based on TCP socket agreement ucLinux data communications functions.In order to provide good customer-browser user interface, use of graphicsprocessing language LabVIEW as a client / server model of the programming language. LabVIEW software development platform focused on the DataSocket mechanism to accomplish real-time data from a network of client server publishing functions, based on the achievement of client / server model of the data collection network monitoring system G language code.Finally, on the development of the plug-in using LabVIEW SQL network database for data collection and control systems.Experimental results indicate that users can collect data on an embedded real-time systems, but also the effective data analysis and achieve long-range monitoring, diagnosis and configuration functions. Plug-Web technology for the realization of the industrial site will be distributed information network technology to control a deliberate attempt, the technology can also be extended to other industrial scene control requirements.
