The Combination Of Coal Mine Safety Management Information System Based On C/S And B/S Model

Due to various reasons, in recent years coal mine and great accident happen from time to tome, still not only giving makes the country huge economic losses, but also to people's life safety brought great threat. So, to improve and enhance the from various coal mine safety production management situation immediate, establish coal mine safety management information system is to improve and enhance the level of safety management of coal mine a important way.Firstly, this thesis analyses and compares the Client/Server (C/S), the Browser/Server (B/S) system structure and its characteristic, combining the characteristics of coal mine safety management with actual concrete. Is put forward based on C/S and B/S model to design combination of coal mine safety management information system.Secondly, based on analyzing the coal mine safety management information system in China, on the basis of the management information system for coal mine safety function and performance of requirement analysis, system, establishing formulated target of the management information system of coal mine safety logical model, painted each functional data flow chart; Completed the system of data dictionary.Again, according to the system's design principle, this paper puts forward a stage and system development process; And on this basis finished the design of the whole system. Then, for the system are respectively partition function module and the function module design; This part of the system is also introduced and the database design process database table structure do a brief explanation of alarm information table, and makes a detailed introduction; To the user interface design.Finally, this paper based on C/S and B/S mixed mode structure of coal mine safety management information system implementation technology. Unifies coal mine safety management information system, and USES the demand on B/S model of information query and public service information release, using C/S completion of the management information system of coal mine safety most daily affairs.This part, mainly from the development tools, function realization and key realization technology aspects of B/S, part of the realization of C/S. For system from the firewall, identity authentication, access control and security analyses user permissions. Thereby ensuring system of network security, from illegal users of the invasion.
