Software Platform Development Of Underground Engineering Disaster Optical Fiber Multi-Parameter Monitoring System

In recent years, Chinese underground engineering construction flourishes, the traffic tunnel engineering and large-scale water conservancy and hydropower engineering are constructing, underground engineering disasters occur frequently at the same time. Underground engineering disasters often cause significant casualties, severe economic losses and adverse social impact. At present, the underground engineering disaster monitoring sensors and the corresponding equipments have been more mature, which can meet the needs of real-time monitoring basically, but the software system shows simple function and single parameter characteristics that severely restricts the further enhance of underground engineering disaster monitoring technology. Especially for the rapid development of optical fiber sensing technology, the sensor species become complete and the demodulation equipment development technology has become more sophisticated, but most of the software systems can only capture the original wavelength data and can’t achieve multi-parameter monitoring and automatic warning function. On the basis of the existing optical fiber sensing hardware system, the topic designs and develops underground engineering disaster real-time monitoring system platform which can measure multiple parameters simultaneously.Based on the needs analysis and business process, this topic presents the overall design of the software platform. On the basis of the functional structure of the system, design the software platform according to the modular design concept and the software platform is divided into user right management module, parameter configuration module, acquisition module, data process module, display module, data management module and alarm module. The system has implemented under the Microsoft Visual C++2008.Use multi-document architecture of MFC to build the overall framework of the system platform and implement multitask processing simultaneously. The overall system interface style is simple and easy to operate.Software platform was adopted socket programming based on TCP and programming based on the Win32API to achieve network communication and serial communication. On the basis of the analysis of its operating mode, build multi-thread software architecture to avoid system blocking and to collect and process multi-parameter information synchronously to meet real-time requirements of the system.By analyzing multi-parameter information, this paper achieves a powerful parameter configuration function, and through arithmetic operations to refresh the data processing module in real time. Use independent memory module to store data to the database, so that achieve the data centralized and efficient management. Presentation layer of the system also displays real-time data by accessing independent memory module. Persistent storage of multi-parameter information is of great significance to the analysis of underground engineering disaster in the future.By designing and debugging, this topic completes the software platform of underground engineering disaster optical fiber multi-parameter monitoring system finally. The software platform runs well and stably in experimental stage to meet the monitoring requirements.
