Abstract: In one example implementation, a sensor apparatus includes a bracket, a first polar plate, a first contact portion, a first leading wire, a rotating shaft, a support frame, a second polar plate, a second contact portion, and a second leading wire. The bracket is of a cylindrical structure with two open ends. The first leading wire is disposed on the first polar plate and an external side of the bracket, one end of the first leading wire is connected to the first contact portion, and the other end of the first leading wire is connected to the first polar plate. The second contact portion is disposed at a first end of the support frame. The second leading wire is disposed on the support frame and the second polar plate.

Abstract: A troubleshooting method, a device, and a readable storage medium are provided, to detect a unidirectional fault in a ring Ethernet and provide a fault recovery mechanism after the unidirectional fault occurs. In embodiments of this application, if determining that a link corresponding to a receiving unit of a first port is in a fault status, the first device performs loopback on the first port, and sends a first continuity check message to a second device via the first port. The first continuity check message carries first indication information. The first indication information indicates that a link corresponding to a receiving unit of a port that sends the first indication information is in a fault status.

Abstract: A queue management method and apparatus are disclosed. The queue management method includes: storing a first packet to a first buffer cell included in a first macrocell, where the first macrocell is enqueued to a first entity queue, the first macrocell includes N consecutive buffer cells, and the first buffer cell belongs to the N buffer cells; correcting, based on a packet length of the first packet, an average packet length in the first macrocell that is obtained before the first packet is stored, to obtain a current average packet length in the first macrocell; and generating, based on the first macrocell and the first entity queue, queue information corresponding to the first macrocell of the first macrocell in the first entity queue, a head pointer in the first macrocell, a tail pointer in the first macrocell, and the current average packet length in the first macrocell.

Abstract: Embodiments of this disclosure provide a data transmission method, a device, and a system. The method includes: The first Ethernet interface of the first communications device receives a first packet, and determines whether first indication information in the first packet indicates that the first packet is a multi-fed packet. When the first indication information indicates that the first packet is a multi-fed packet, the first communications device drops the first packet. The first Ethernet interface is an Ethernet interface used by the first communications device for connecting to a second communications device.
