Abstract: A locomotive wireless multi-heading remote distributed power traction operation control system. A set of differential multi-heading control unit (8) is added to a train control and management system of an original locomotive, and is combined and fused with a train control and management system (21), a brake control unit (24), a train safety monitoring device (20), a locomotive logic control unit (23), and a locomotive third-party device (25) to implement wireless multi-heading distributed power traction control operation of locomotives in a heavy haul combined train, and adapt to train multi-heading traction control operation of differential locomotives of a heavy haul combined train or multi-heading operation of different railway locomotives. Also provided is a multi-heading locomotive.

Abstract: The present disclosure relates to a device, method and storage medium for wireless communication. Various embodiments regarding multi-beam sensing and access are described. In an embodiment, an electronic device for wireless communication includes a processing circuit, and the processing circuit is configured to initiate a plurality of listen before talk (LBT) procedures on a plurality of beams; for an LBT procedure on a first beam of the plurality of beams, determine that a first threshold number of successful clear channel assessment (CCA) detections have been completed; for an LBT procedure on at least one other beam of the plurality of beams, determine that a corresponding threshold number of successful CCA detections have not been completed; and determine whether at least one additional CCA detection is to be performed on the first beam.

Abstract: Disclosed in the present invention are a heavy-haul train and a longitudinal dynamics traction operation optimization control system and method thereof. A model prediction function is added to a locomotive wireless double heading system so as to suppress large longitudinal impulse that is likely to be generated when the operation speed of the heavy-haul combined train is regulated, especially when the heavy-haul train is switched at a grade change point working condition, and the major potential safety hazard that affects the safe and stable operation of the heavy-haul combined train is avoided.

Abstract: An offshore floating-type wind power combined semi-submersible platform foundation has at least three stand columns that form an enclosure having a polygonal structure. The adjacent stand columns are connected by an upper support and a lower support. Each stand column is composed of an upper column body and a lower column body that are arranged coaxially. An upper portion of the upper column body is provided with a support block, the upper support rests on the support block. A lower portion of the upper column body is provided with a lower support connecting portion that is connected to the lower support. With the structural form of the offshore floating-type wind power combined semi-submersible platform foundation, the requirements for a manufacturing site and a combination site are greatly reduced, providing the possibility of large-scale offsite construction.
