The Research And Development Of The Security Monitoring System For Reticulated Structural Coal-shed

The reticulated structural coal-shed has been applied in our country for no more than ten years. Several collapsed accidents of coal-shed have been found recently. Whereas the research of the security monitoring technology for this architectural structure is almost blank. In order to enhance the security of coal-shed, extend the life-span, avoid the accident's happening, the thought of developing the security monitoring system for coal-shed is brought forward in this. And also the original shape is carried into execution.In this thesis the background of the subject is brought out firstly. Then it described the application of the reticulated structural coal-shed and the spacial structure. According to the application of monitoring technology to the other special structure, the monitoring method for the reticulated structural coal-shed is discussed. And the monitoring thought of this system is brought forward. The thought is that according to the relative displacements of coal-shed's characteristic nodes, the state of coal-shed is estimated and the proper maintaining proposition is provided.Based on the objects to be monitored and the thought of monitoring, the full-scale structure of the monitoring system is brought forward. And then the function modules of system are analyzed. And it introduces the hardware and the software platform which are demanded in the system.Set out from the basic concept of database, this thesis analysed the requirement of security monitoring system's data. And then it designed the system's database structure, tables, indexes, and relations between tables.In the thesis it uses the ADO model to query the data which the user required. And with the supports of the message respond mechanism of Windows MFC, the real-time monitoring modules are set up. and realized the real-time monitoring function.Set out from the basic theory of faults diagnosis, in this thesis the basis of faults diagnosis for security monitoring system is analyzed. Then the faults diagnosis modules are designed, the primary monitoring index and knowledge system is shaped.The application of the security monitoring system of reticulated structural coal-shed will monitor the security situation of coal-shed effectively. From the prediction and estimation of characteristic nodes' situation, it can give a clue to the points that need to be repaired. And then it remind the maintainer to take a good measure to avoid the accident and the economy losing that arose from the invalidation of coal-shed's poles. The application of this system has important utility value, society significance and economy significance.
