Abstract: The present utility model relates to the technical field of agricultural planting equipment, in particular to a sectional arched tunnel connected by tension, which comprises a first connecting rod and a second connecting rod between which a metal connector is connected. Both sides of a surface of the metal connector are provided with threaded connection holes, and both ends of the metal connector are provided with connecting holes. The present utility model can adapt to different ridge widths by changing number and bending amplitude of the connecting rods and it is convenient to connect without pressing, so as to meet requirements for different ridge widths.

Abstract: A data transmission method is implemented by a first electronic deviceand includes displaying a first window and a second window, where the first window displays a projected interface of a second electronic device, and the second window displays a projected interface of a third electronic device; detecting a first input instruction that acts on first information in the first window; sending a second input instruction to the second electronic device based on the first input instruction, where the second input instruction instructs the second electronic device to determine the first information; receiving, from the second electronic device,first transmission information about the first information; detecting a third input instruction acting on the second window; and sending, to the third electronic device based on the third input instruction, second transmission information generated based on the first transmission information.

Abstract: A graceful restart (GR) method of a router, and a router and a communication network thereof are provided. The method includes the following steps. A control plane enters a GR state. Label switched path (LSP) packets sent by a neighbor router are received, and the label information of the control plane is recovered according to the LSP packets. Whether the label information is completely recovered is determined. If the label information is completely recovered, the GR state is exited, and label information of a forwarding plane is updated according to the recovered label information of the control plane. The GR method of a router, the router, and the communication network decide whether to exit the GR state by detecting whether the label information of the control plane is completely recovered. This can precisely control the time of exiting the GR state is controlled and improve the reliability of the router.
