Abstract: This application discloses a link fault handling method, a related apparatus, a storage medium, and a program product, and belongs to the field of communication technologies. In this method, a forwarding plane component of a network device updates a reference state table in time by actively polling a port status register, so that when forwarding a data flow, the forwarding plane component can sense a local faulty link in time based on the reference state table, and perform link switching in time, and a PHY chip does not need to report fault information to a control plane CPU in the network device, or wait for the control plane CPU to deliver an instruction. That is, this solution does not depend on control plane path computation, and does not require additional communication from a data plane to a control plane, to avoid a delay caused by fault handling of the CPU.

Abstract: A laser radar integrated device, including a cover plate (Q10, M10, N20, P60), a fixed support (Q20), a lifting structure (Q30), a pop-up structure (Q50), a laser radar (Q60), and a controller (Q70, D50). The cover plate (Q10, M10, N20, P60) is located on a vehicle fender (Q80, M200, N200, P200) and matches with the size of an opening in the fender (Q80, M200, N200, P200); the fixed support (Q20), the lifting structure (Q30), the pop-up structure (Q50), the laser radar (Q60) and the controller (Q70, D50) are located inside the fender (Q80, M200, N200, P200); the lifting structure (Q30) is disposed on the fixed support (Q20) and connected to the cover plate (Q10, M10, N20, P60); the laser radar (Q60) is disposed on the pop-up structure (Q50) which is disposed on the fixed support (Q20). Also disclosed is a vehicle provided with a laser radar integrated device.
