A method for monitoring a distributed antenna system includes: at a relay device, receiving a first operation monitoring signal sent by the near-end device, where the first operation monitoring signal carries an operation monitoring message, and the operation monitoring message includes a device address of a monitoring target device; determining whether to analyze the first operation monitoring signal according to a connection status with the near-end device; in response to a determination to analyze the first operation monitoring message signal, analyzing the first operation monitoring signal to confirm the monitoring target device and to determine whether to respond to the operation monitoring message; and in response to a determination to respond to the operation monitoring message, responding to the operation monitoring message according to the monitoring target device as confirmed.

A power divider network includes a cover plate, a reflection plate, a support component, and a feed line. The reflection plate is arranged separately from the cover plate. A first surface of the reflection plate is a reflection surface. A plurality of connectors protrude from a second surface of the reflection plate opposite to the reflection surface. The plurality of connectors are arranged at intervals. The plurality of connectors are coupled with the cover plate and divide the space between the reflection plate and the cover plate into at least one hollow chamber. The support component is at least partially arranged in the hollow chamber. The feed line is arranged in the hollow chamber and mounted at the support component.

The present disclosure provides a phase-shifting assembly, including an antenna phase shifter and a drive apparatus. The antenna phase shifter includes at least one first phase-shifting fixed unit, at least one first phase-shifting movable unit, and at least one first phase-shifting rotation mechanism. The drive apparatus includes a power mechanism configured to provide a drive force to the antenna phase shifter, a first rotation member connected to the power mechanism and coupled to the at least one first phase-shifting rotation mechanism, and a position-limiting member configured to limit the movement of the first phase-shifting rotation mechanism in an axial direction of the first phase-shifting rotation mechanism. The first rotation member transfers the drive force of the power mechanism to the first phase-shifting rotation mechanism through the first rotation member to control a relative movement between a fixed phase-shifting trace and a first movable phase-shifting trace.

A transmission apparatus includes a gear, a rack, and a fixture mechanism. The gear includes a first stopper and a pivot shaft. The first stopper is arranged at at least one end of a gear member extending along a longitudinal axis of the gear. The rack meshes with the gear in an assembly state and includes a second stopper corresponding to the first stopper. The fixture mechanism includes a gear fixing hole and a guidance groove. The gear rotates relative to the fixture mechanism via the pivot shaft. The pivot shaft passes through the gear fixing hole. The rack translates relative to the fixture mechanism through the guidance groove.

A transmission mechanism includes: a drive shaft; and a stopper assembly, the stopper assembly including: a base, including a first thread; and a rotating component, positioned on the driving shaft, rotatable with the driving shaft, and including a second thread to engage the first thread, wherein at least one of the base and the rotating component is configured with a stopper; when the drive shaft rotates, the rotating component rotates with the drive shaft and slides relative to the base through an engagement of the first thread and the second thread; and when the stopper resists the base or the rotating component, a relative sliding between the base and the rotating component stops.
