Abstract
In the process of coal quality management by CHN Energy Group Shendong Coal Group Co., Ltd., there are problems such as insufficient data sharing, low efficiency of manual coal quality prediction and labor-intensive coal quality inspection and assessment. In order to solve the above problems, based on the coal quality management business process, this paper designs a coal quality whole process management system. The system uses a combination method of workflow technology and status control fields to achieve coal quality information sharing among different departments, which enables coal quality data to flow quickly among different departments and ensures the traceability, uniqueness and accuracy of the data. Through the RBAC(role-based access control) permission control model based on the tree structure function module, the proposed system simplifies the system permission configuration, ensures the validity and security of coal quality data flow and prevents 'illegal users' from invading the system or 'legal users' from accidentally operating the system and causing data loss. The system realizes the input, analysis, sorting and statistics of coal quality related data, and forms corresponding coal quality reports/graphics and coal quality prediction plans, etc. It is helpful to provide the real-time monitoring of coal quality information for management departments at all levels and ensure the timeliness, authenticity and security of coal quality information circulation.
