Abstract: The present invention discloses a multilevel pattern monitoring method for a process industry process and belongs to the fields of industrial production and processing. The multilevel pattern monitoring method comprises the steps: dividing an industry process into a plurality of levels from the view of patterns, selecting a different key performance index for each level, acquiring operating data relevant to the key performance index, identifying the pattern of each level, and proposing a pattern monitoring method for each level based on a data driven method to realize pattern monitoring in the industry process.

Abstract: A method and apparatus for analyzing a bitumen-containing process stream and controlling a process. The method including directing a beam of infrared light at the bitumen-containing process stream, capturing light corresponding to the infrared light after interaction with the bitumen-containing process stream, and analyzing the captured light to obtain a spectrum. A composition estimate can be generated based on the spectrum and a calibrated model. A controller is operative to adjust a setpoint of the process in response to the composition estimate.

Abstract: The invention discloses an access apparatus and method for digital subscriber line test. The apparatus includes: one or more distributed access matrix control modules, one or more distributed access matrixes; and a power converter module. The distributed access matrix control module is connected to a test module and at least one of the one or more distributed access matrixes which is under the control of the distributed access matrix control module, and is configured to send a test task initiated by the test module to the at least one distributed access matrix and report a message from the at least one distributed access matrix to the test module. The distributed access matrix is configured to connect a tested subscriber in accordance with the test task and report an access success message to the distributed access matrix control module.
