[Abstract]:With the development of computer technology and Web technology and the improvement of enterprise automation and information technology, the shortcomings of traditional industrial control system appear day by day, which can not meet the real-time requirements of data release. And the control coverage is subject to geographical restrictions. The research and design of modern remote control system, which breaks through the limitation of region and time, has become a trend. This paper presents a design scheme of antenna rotation control platform system, which enables users to remotely control the antenna and real-time feedback the antenna position and operating conditions. The main research results obtained are: 1.The platform is based on B / S (browser / Server) architecture. Taking the network antenna rotation control platform as the research object, using the advanced visual development platform of Microsoft Visual Studio 2008) and combining with the SQL Server database, the upper computer Web server program is written in C # language, which significantly reduces the amount of code writing. It improves the development efficiency, shortens the development cycle, and ensures the standardization and standardization of the code .2.Using the advantage of web page design technology and the advantages and powerful functions of ASP.NET 2.0, a good man-machine interactive network interface is developed. The real-time and user interface friendly degree of the system is improved by AJAX technology, and the real-time display of Web page is realized. 3. Socket communication technology is used to complete the communication between the upper computer of the control platform and the control unit of the terminal antenna equipment. The control of antenna rotation angle azimuth (including single step control, continuous control and fixed point selection control) is realized, and some parameters of antenna equipment such as voltage, current, temperature, etc. Monitoring of humidity and working status. 4. The platform uses multi-thread technology to effectively accomplish resource allocation. Make different program modules concurrent asynchronous execution to improve the equipment operation efficiency .5.Designs the corresponding database to persist the user information and antenna operation parameters between the storage platform system and the on-site acquisition equipment. The real-time storage of data and the sharing of data in the Web rotating antenna control system are realized. By debugging the equipment, the designed Web rotating antenna platform can meet the requirements of practical application and can control the remote equipment in real time. At the same time, the operating condition of the equipment can be monitored all the time, and it can be processed automatically in case of predicted danger. In conclusion, the platform has good real-time, reliability and flexibility. It can effectively realize the remote control and fault warning of distributed unmanned equipment in the production process, which has a good promotion value.
