    摘要: Provided is an industrial process soft sensor method based on a federated stochastic configuration network, including: acquiring historical industrial process auxiliary data and corresponding product quality data; finding out optimal hidden layer parameters; processing, by a central server, to obtain global parameters, and downloading same to each factory as hidden layer parameters for a local model; obtaining output weights of a current network through an optimization algorithm, and uploading same to the server for weighted aggregation; and when the number of hidden layer nodes in a current network exceeds a maximum given value or a residual in current iteration meets an expected tolerance, completing modeling to obtain the global federated stochastic configuration network without adding new nodes. The present disclosure effectively improves prediction performance of models and protects data privacy, thus meeting industrial process soft sensor requirements.

    摘要: An intelligent control method for a dry dense medium fluidized bed separator includes supplying air to fluidize a bed; estimating an initial bed density according to a washability curve of a raw coal; detecting a magnetic material content in the bed to obtain a real-time bed density, and adjusting the real-time bed density according to a result from an analysis on a deviation from the initial bed density; during separation, adjusting a medium addition amount and a scraper discharge speed to maintain a stability of a bed height; separating the raw coal in the dry dense medium fluidized bed separator to obtain a clean coal product; and detecting a product ash content of the clean coal product, comparing the product ash content with a target ash content, and if a difference between the product ash content and the target ash content exceeds an expectation, adjusting the initial bed density.
