The invention provides a data transmission method and device, and relates to the technical field of wireless and core networks and the technical field of edge computing, the method is applied to a robot, the robot is internally provided with a first 5G device-to-device D2D functional chip module, and the method comprises the following steps: transmitting collected data to a user terminal based on the first 5G D2D functional chip module; and the user terminal is internally provided with a second 5G D2D functional chip module. According to the application, the 5G D2D functional chip modules are deployed on the robot and the user terminal, and D2D direct communication between the robot and the user terminal can be realized based on the 5G proximity service (D2D) capability; based on the 5G technology, the advantage of wide coverage of the 5G base station can be exerted, and ultra-long-distance wireless image transmission is realized through local area network direct connection and base station relay.

The invention discloses a load balancing method and system. The method comprises the following steps: determining response coordination configuration information of the distributed coordination system for each real server configuration; querying a transmission target corresponding to the target real server based on the response coordination configuration information corresponding to the target real server; when the transmission target corresponding to the target real server is the target load balancer, forwarding a response message corresponding to the client request message returned by the target real server to the load balancer, and forwarding the response message corresponding to the client request message returned by the target real server to the target client through the load balancer; and when the transmission target corresponding to the target real server is the target client, directly returning a response message corresponding to the client request message to the target client through the target real server. According to the scheme, the pressure of the load balancer connected with the distributed coordination system is relieved, and the load balancer is prevented from becoming a system bottleneck.

The present invention provides a camera video playback method, device, system and electronic device, the method comprising: after detecting a target camera video playback request for a target camera, determining a target playback address indicated by the target camera video playback request, the target playback address including a target camera identifier of the target camera; sending a push stream request for the target camera to a camera platform based on the target camera identifier through a target playback agent, so that the camera platform issues a push stream instruction to the target camera; receiving an audio and video stream pushed by the target camera, generating a target playback file corresponding to the target camera video playback request based on the received audio and video stream, the target playback file including at least one slice to be played; playing the slice to be played in the target playback file through a target player, so as to play the video of the target camera. The embodiment of the present invention can conveniently play camera videos to effectively save costs.

The invention relates to a time synchronization system and method based on CANXL and Ethernet message conversion, the system comprises a main clock node, an edge gateway and an edge device, the edge gateway fills an Ethernet MAC frame into a data segment of a CANXL message; after receiving the CANXL message, the edge equipment screens the message according to the ID, processes the message, extracts an Ethernet MAC frame and records a timestamp at a receiving moment, the Ethernet MAC frame is processed by a protocol stack to obtain a feedback message, fills a data segment of the CANXL message, packs the feedback message into the CANXL message and sends the CANXL message, and the timestamp at a sending moment is marked at a corresponding position of the message; and the edge gateway unpacks to obtain an Ethernet MAC frame and sends the Ethernet MAC frame back to the master clock node through the Ethernet, and the edge device calculates frequency deviation and propagation delay with the master clock node according to a time synchronization protocol and adjusts a clock of the edge device to complete synchronization with the master clock node. According to the invention, the time synchronization precision can be effectively improved.

The application discloses a container management method, system and device for a space-based cloud platform and a medium, relates to the fields of aerospace and cloud computing, and the container management method comprises the following steps: packaging a container application to be run to generate a container image data packet; compiling source files of a management tool corresponding to the container image data packet into an executable file; executing the executable file to generate a specified application directory and store the container image data packet in the specified application directory; creating an independent data directory for the container and binding the data directory with a fixed path in the container; when the container is started, creating an inter-process communication System V IPC mechanism according to a first configuration file created in advance, and sharing an IPC namespace of the container and a host computer according to the IPC mechanism, so that multiple containers coexist and data does not interfere with each other, and the management process of the host computer and the container can directly communicate, the efficiency is high, and the real-time requirement in the space-based cloud platform scenario can be met.
