Cooperative Mechanism And Key Technologies For Coalmine One-map

Coal is the most important energy resources in China. The data of coal mine has an important influence on the work safety and production capacity of coal mine.Due to the characteristic of various kinds, large amount, updating fastly and frequent interaction in coal mine data, there are still problems in the management and application of the existing coal mine data, such as the difficulty of inquiery, statistic, updating, sharing.According to the complexity and problems above, the thesis studied on designing and impling of cooperative services in coal mine to solve the interaction problems between the application system and the data of coal mines. The design and implementation of one-map data storage system includes spatial database and distributed storage system tiles. Also, the map service and search service were designed and impled, which constitute the cooperative system with cooperative services. And the Web service system, including load balance, is studied to ensure the the system efficiency of coalmine one-map. Moreover, some study on the design and implementation of identity authentication service in distributed system, as well as the key technologies of database cluster and load balancing, reading and writing separation, has been done.Finally, the prototype system is implemented in a group of coal mines, and the key technology of the research is verified by experiments. At the same time, how to manage a variety of services in the system to facilitate the deployment, operation and maintain the system was studied. The experimental results show that the coalmine one-map system is able to well fulfill the interaction requirements between the professional application system for coal mine and the data of coal mines, the coal mine data consistency, sharing, updating and integrity achieved, as a result.
