Qing Ji Zhang, Luo Zhong, Jingling Yuan, Qingbo Wang · International Conference on Electric Technology and Civil Engineering · 2012
A kind of tunnel environment monitoring system based on SCADA (Supervisory Control and Data Acquisition) and Qt integrated development environment was designed and realized in this paper. The data center module, interface module and data processing module were integrated. The observer pattern was applied to this system including custom widget technology, XML technology, and database technology and so on. A lot of configuration parameters were selected for the extension of this system. This system was proved having a good expansibility, reusability, flexibility and maintainability in the practical engineering.
