Abstract


With the continuous development of network technology, the remote monitoring system in the tunnel monitoring also increasingly showing its advantages, remote monitoring and control, fault diagnosis, decision support functions provide a powerful means for the safe operation of the tunnel traffic effectively protect managers can remotely in real time learned to control field equipment status and traffic conditions, which greatly improve work efficiency. This paper first reviews the remote monitoring system theory, technology development status, and the level of remote monitoring systems, functions, as well as the implementation of a more in-depth study and discussion. Second, the characteristics of the remote monitoring system of the B / S architecture, the paper focuses on the key technology of the remote monitoring system, data communication, and real-time data storage. Finally, a set of remote monitoring and control system based on B / S structure implementation, combined with the characteristics of urban highway tunnel design and implementation of a remote monitoring system based on B / S structure of the tunnel, and test the real-time system and security. The results of this research mainly includes the following aspects: (1) In this paper, the remote monitoring system based on B / S structure with a combined implementation of on-site monitoring and remote monitoring. Site monitoring based on both historical database communication with OPC data communication data exchange technology, traditional real-time monitoring of the database, the client uses ActiveX controls and OPC server to communicate directly, greatly improve the data real-time to ensure the reliability of the remote monitoring system. (2) The system uses ActiveX-OPC-PLC network communication structure to achieve remote device and instrument control in heterogeneous network environment, remote users via an ActiveX control to modify in real-time parameters of the OPC server remote control, change the traditional remote monitoring system can monitor only and the lack of lack of means of control, and at the same time, the system will be real-time and historical data to chart visual display to help management better decision-making. (3) the data acquisition module using the method of combining memory database and history database, allowing the system to better deal with the large amount of data, real-time data acquisition monitoring, to provide data protection for remote monitoring systems, to improve the stability of the system . Combined in the final stages of the actual project designed and implemented a remote monitoring system based on B / S architecture, urban highway tunnel can be seen through the practical application of the system to meet the the tunnel monitoring real-time high amount of data demand, reference significance and practical value.
