Study And Development Of Coal Quality Management Information System Based On UNIX

In coal analysis laboratory, the coal quality data is many and the management is very difficult, so the traditional methods still adopted at present which using the paper recording test data and compiling the computation by man-power can't satisfy the modern production management requirement. So it is imperative to establish a perfect management information system. Establishing a coal quality management information system based on coal analysis laboratory is very representative, it can provide technical support for coal quality management information system of coal enterprises. So the study has important application value and widespread market prospect.This paper elaborated the main functions, organizations and the information transmission among different departments, analyzed the testing flow and the data flow emphatically by taking Xinjiang coal field geology bureau comprehensive laboratory as an example. Through the analysis of the system development, the B/S network construction and the methods of SSA&D united Prototyping pattern was confirmed. Also UNIX system was taken as operating system, database system ORACLE, FORM BUIDER,PHP,PRO~*C were taken also. According to the laboratory requirement and system development logical demand, the modules dividing to the system was done in this paper, and introduced the various modules function, analyzed the modules development flow. Finally, established a coal quality database system, realized the coal analysis processing automation and the network. In addition, the entire process of system database design, system security and code realization were also introduced in this paper.The practice proved that the system with the UNIX operation and B/S construction had many advantages such as fast running rate, high security and also could satisfy the mass data processing requirement; the pattern of SSA&D combined with prototyping method could reduce the development cost and time. using the combination of FORM BUILDER,PHP,PRO~*C could display their strongpoint, and realize their optimization effect. Also the system security could be guaranteed efficiently by using multi-layered security measure.
