Along with fast development of our country national economy and unceasing development of hydro-electric resources , the water conservation and electricity enterprise has also obtained the achievement which attracts worldwide attention. Since the founding of the nation, our country altogether has constructed the near 86,000 each kind of reservoir, the reservoir inpoundment total quantity reaches 500,000,000,000 m3, which is equal in the national runoff total quantity 1/6. These water conservation and electricity project and the corresponding building have played the vital role in development use of flood prevention, electricity generation, aquaculture and tourist resources aspects and so on, and has obtained the significant social efficiency and the economic efficiency, it is the national economy foundation industry and the infrastructure.
Because of the various reason of the hydrology, the geology, the construction quality, the material get older, the movement management and so on, there had some problems in the partial dam , and there affected benefit display of these project, even threatened the downstream people's life and property safety. Because the hydrology, the geology, the construction quality, the material get older, the movement management and so on the various reason, the partial dam existence security problem, is affecting these project benefit display, even threatens the downstream people's life and property safety. For the reservoir security, it must implement the reservoir safety observation.。Because of many observation project in the reservoir, and along with the observation age limit increase, it will accumulate the massive observed data, and the work is huge to carry on processing and the analysis work loading to these materials, and sometime it will have to entrust the unit concerned generally to complete with 1-2 year, thus it will not be able to analyze the achievement to use in monitoring promptly the water conservation building the safety operation, it also will not be able to discover the hidden danger promptly, and miss an opportunity because of a delay, and cause the nonessential losses. Therefore, using fully current computer software and hardware technology to develop hydraulic engineering information management system, we carries on the scientific management to the project observed data, and performs the quantitative analysis qualitatively, and realizes to the building real-time monitoring, not only can enhance the engineer's unit greatly the working efficiency, but may promptly provide the policy-making basis for the leadership, and it is now development tendency of the informationization social.
Based on dam safety monitoring information system management principle, the method and the process, it has studied thoroughly to how to organize to manage in the dam safety monitoring massive data, the graph information as well as the data processing,and how simultaneously to develop the system architecture which might expand, and may promote to make the detailed analysis. Finally,it applied the above theory to Songshanxia dam safety monitoring information management system development. This article obtains the main research results to be as follows:
(1) According to specialized characteristic of the dam safety monitoring information management system , information system in composition, classified as well as information system concepts and so on model have been studied; And it discuss merits of the B/S and the C/S integration mixed three structure, and it will cause the system between the performance, openness and the flexibility to achieve the good balance.
(2) In view of the dam safe monitor characteristic, the function module design of the information system has been studied in detail.
(3) Using the E-R data model to optimize the database structure , it enhances the data storage and the controllable management effectively. And it discusses the information management system database as well as the network security strategy.
(4) It studied graph technology of the information management system and realization main points in the network. And data mining treating processes of the dam safety monitoring information has been discussed .and data mining to apply the platform the skeleton has been constructed .
(5) Based on the module technology of software integration, it has realized the rationality and the scientific nature of module decomposes of the large-scale complex system .
Obtained research results of this article have the important application and the promoted value in the water conservation profession information management.
