Distributed Remote Monitoring System Key Technology Research

Distributed remote monitoring system has been applied to all areas of life, such as vehicle monitoring control system, street lamp monitoring control system, elevator monitoring control system and so on. Therefore, it is very important to study and resolve the key performance of the distributed remote monitoring system.The system is designed to consult with the previous development of the vehicle monitoring system and street lamp monitoring system of Nanjing University of Science & Technology. According to the requirements of the new project, it is very essential to analyze the previous system and bring up new solutions to the key performance of distributed remote monitoring system. In the thesis, according to the solutions to the project, the content is comprised of four issues. The first one is about the system architecture design. Considering the requirements of the asynchronous updating of the Web page, the platform of ASP.NET AJAX is applied to the thesis. The second one is about the optimization of the database structure and query statement, which is a solution to the defect of the previous system. The third one is about how to display the control information effectively. Through the application of the AJAX technology, the real-time controlling information can displayed to the user immediately. Using Third-party control can draw the curve of the information, which is easy for the users to analysis the information. The fourth one is the security of the distributed remote monitoring system. All of these are the contents of this paper.
