Abstract: A data synchronization device is provided, including a control module, a data block storage module and an encoding/decoding module. A data synchronization method using the device is also provided, including: selecting, by the control module, a data transmission network node and selecting the to-be-synchronized data block of a data transmission network node from the data storage module; encapsulating the to-be-synchronized data block in a specific format and then broadcasting the encapsulated data, where if there are two or more to-be-synchronized data blocks, the to-be-synchronized data blocks are encoded and then encapsulated; otherwise, the to-be-synchronized data block is directly encapsulated; processing, by the encoding/decoding module, the encapsulated data to obtain the to-be-synchronized data block, and finally inputting the obtained to-be-synchronized data block into the data block storage module.

Abstract: Disclosed are a method and device for implementing an ad hoc network routing protocol in a multi-agent system. The device includes a trajectory information acquisition module, a data packet delivery module, a delivery confirmation module, a data packet forwarding module, a data transmission feedback module and a data storage module. The method includes: acquiring a separation and rendezvous timing table and an adjacency matrix of an ad hoc network composed of multiple agents at a given moment; if a source node has message sending requirement, performing data packet delivery and delivery confirmation based on the separation and rendezvous timing table and the adjacency matrix; and performing data packet forwarding and transmission status feedback by a non-source node.

Abstract: The invention discloses a protective device for the occurrence of a mine roof fall, which includes a machine body. A load-bearing cavity 72 is provided in the machine body 10, a load-bearing platform 11 is fixedly arranged on the lower side of the machine body 10, and four circumferences of the machine body 10 are evenly distributed on the outside. The cavity 69 and the load-bearing cavity 72 are provided with a weight-bearing device 75 for lifting a weight. The weight-bearing device can withstand the falling top plate, and the hydraulic cylinder therein can make the device bear the pressure of the top plate on the device and fix the device at the same time. The stabilizing device can keep the device in a stable state under the action of pressure, will not fall, and share part of the pressure. The load-bearing device can support the device to support the pressure on the roof of the mine and drill into the ground.

Abstract: A thermally insulating protective sleeve. The thermally insulating protective sleeve comprises a tubular shell and a thermally insulating liner located in the tubular shell and made of a thermally insulating soft material. The shell comprises two longitudinally separated half-parts, the two half-parts being detachably connected to each other. The thermally insulating liner defines a hollow opening in the shell, and an object to be thermally insulated can be received in the hollow opening in such a way that the thermally insulating liner is subjected to pressure in a radial direction.

Abstract: A gas pressure tank structure including: a tank wall, a compression oil cylinder, a locking ring, a spring cylinder, a locating pin mounting hole, a dowel pinhole, a refractory brick, a guide mechanism, a sealing structure, an arc joint, an arc shaped tank bottom, a steel ladle stand, a tank cover, and a reinforcing board.
