Abstract:At present, the work ticket in the production information management system of most hydraulic power plants is only established in a certain maintenance work and exist in isolation, and there is no systematic arrangement of the maintenance work, and there is no effective intelligent technical means to manage the multiple work tickets at the same time. At the same time, the lack of intelligent technical support in the processing of work tickets, such as ticket review and cancellation, often leads to low efficiency and easy omission of work tickets. In this paper, through the analysis of the shortcomings of the current work ticket processing link, combined with the needs of the power plant operators, The mass work ticket and operation ticket data field in the current production management system are analyzed, and the data mining technology is used to design and develop a set of support system for the work ticket of the hydropower plant. The system can realize the functions of automatic ticket trial, ticket reference, security inquiry, operation item query and so on. It can solve the previous work of complicated manual inquiry and check, which can greatly improve the work efficiency and greatly improve the level of safety management.
