The accurate identification of large and medium slag in power plant slag transport system has an important impact on the safety, efficiency, environmental protection and economic benefits of power plant. The timely processing of large slag can effectively improve the operation efficiency and maintenance cost of power plant, and with the rapid development of image recognition technology, the recognition of large slag in power plant slag transport system is gradually intelligent. In this paper, based on CenterNet image recognition algorithm, through the adaptive spatial feature fusion module is added in the backbone network, and combined with the feature of the pyramid networks structure. The low-level feature information is fused with the high-level feature information. The loss function is replaced by the distributed focus loss, and the effectiveness of the system is verified by experiments. The results show that the system has good convergence, can accurately identify the size and position of large slag block, can respond to the slag removal command quickly, improve the operation efficiency of the power plant slag delivery system, reduce the manual maintenance cost, and improve the operation safety of the power plant.
In recent years, with the rapid development of intelligent technology, the slag transfer system of power plant is in urgent need of intelligent upgrading. In this paper, in view of the hidden safety problems of the slag transport system, through the intelligent upgrade of the slag transport system, the slag intelligent monitoring and fault warning control system is built. The results show that the system can automatically calibrate the fault point of the equipment, make early warning and identification of the fault, and improve the response speed and efficiency of the power generation enterprise. The system can not only reduce the working intensity of operators, but also ensure the safety and stability of equipment operation to the greatest extent. The system realizes the on-line evaluation and prediction of slag system equipment status, and guarantees the safe and stable operation of the unit, which has important significance for ensuring the safe and stable operation of the boiler.
