| Because the long time saving storage and high frequency usage of deformation data, especially on use of automation surveying, data analysis and forecast, experts from here and abroad have been constructing the deformation monitoring data management and analysis system. Basing on the temporal and spatial characteristics of deformation data this thesis analysis the need of deformation monitoring, build the framework and implement each functions and achieves the following results:1. This thesis have studied deformation monitoring information pretreatment, commonly used analysis methods and analysis models, improved MGM(l,n) model, linear interpolation method basing on multidimensional space. Point out satisfying the needs of four categories of analysis methods and models the universal system has to achieve multi-sensor data query, and space domain data associating with time-space domain data query. Meanwhile system need design common used analysis interface.2. Basing on the theory described this thesis has designed the architecture of heterogeneous sensor database of deformation monitoring, in which every sensor will get two main tables and other tables to save space domain and time space domain data and the relation of the data, on which users can extend database to ensure heterogeneous sensor data can be saved. By means of math logic this thesis has proved the database extended by users is fitted for 2NF,3NF and BCNF.3. Basing on the database architecture this thesis designs common use query solution, which can realize custom directory tree, multi-sensor data query, and space domain data associating with time-space domain data query, which satisfy the deformation analysis needs.According to the theories above this thesis designs the uniformed interfaces of data entrance and analyze and uses SQLSever database management and.Net framework to implement the universal deformation monitoring system, and applies to two different projects to prove the practicability of the system... |
