Abstract: A nuclear emergency multifunctional operation robot includes a base, a mechanical arm, a tool change-over device, and motion supporting devices. The base includes a pedestal, a mounting seat A, a mounting seat B, a mounting seat C, a rotation driving mechanism A, and a rotation driving mechanism B. The front end of the mechanical arm is connected to the mounting seat B; the tool change-over device includes a male connector and a female connector which are abutted with or separated from each other; and the motion supporting devices are used to drive the nuclear emergency multifunctional operation robot to move. The present disclosure has the advantages that the base can be integrated with various end tools, so that the operation robot conveniently changes over tools according to operation needs to conduct various types of operations.

Abstract: A method for constructing and training a Decentralized Migration Diagram Neutral Network (DMDNN) model for a production process, including: determining a production task input management node, distributed management nodes and a granularity of each of the distributed management nodes, and constructing a production system network; constructing network calculation nodes on each of the distributed management nodes; constructing and training a DMDNN model; and applying the trained DMDNN model in management and control of the production process.

Abstract: It is described a method for pushing media information in real time, where information of user focus on a current page is determined, a keyword is searched for according to the information of user focus, and media information matching the found keyword is pushed in real time. It is also described a device for pushing media information in real time. With what described, it is possible to improve real-time performance and accuracy in pushing media information.
