Monitoring method, control module and computer medium of distributed antenna system

A control module in a distributed antenna system, the distributed antenna system including a near-end device, one or more relay devices connected to the near-end device, and one or more far-end devices connected to each relay device, the control module comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing instructions for execution by the at least one processor that, when executed by the at least one processor, cause the at least one processor to perform:
• receiving a first operation monitoring signal sent by the near-end device through a first optical port of the near-end device, wherein 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, by a second optical module of the relay device, to analyze the first operation monitoring signal according to a connection status with the near-end device;
• in response to a determination by the second optical module of the relay device to analyze the first operation monitoring message signal, analyzing the first operation monitoring signal to confirm the monitoring target device;
• in response to the monitoring target device corresponding to the second optical module of the replay device, determining to respond to the operation monitoring message;
• and
• in response to a determination by the second optical module of the relay device to respond to the operation monitoring message, responding to the operation monitoring message according to the monitoring target device as confirmed, comprising:
• determining whether the monitoring device is the relay device or a far-end device associated with the relay device;
• in response to determining that the monitoring target device is the relay device, obtaining operation information as requested by the operation monitoring message, as a response to the operation monitoring message
• in response to determining that the monitoring target device is the far-end device associated with the relay device, sending a second operation monitoring signal through a third optical port of the relay device, the second operation monitoring signal carrying the operation monitoring message.

A non-transitory computer-readable storage medium on which computer program code is stored, and the computer program code, when executed by a processor in a distributed antenna system, cause the processor to perform:

• at a relay device, receiving a first operation monitoring signal sent by a near-end device through a first optical port of the near-end device, wherein the first operation monitoring signal carries an operation monitoring message, and the operation monitoring message includes a device address of a monitoring target device, wherein the distributed antenna system includes the near-end device, one or more relay devices connected to the near-end device, and one or more far-end devices connected to each relay device;
• determining, by a second optical module of the relay device, to analyze the first operation monitoring signal according to a connection status with the near-end device;
• in response to a determination by the second optical module of the relay device to analyze the first operation monitoring message signal, analyzing the first operation monitoring signal to confirm the monitoring target device;
• in response to the monitoring target device corresponding to the second optical module of the replay device, determining to respond to the operation monitoring message;
• and
• in response to a determination by the second optical module of the relay device to respond to the operation monitoring message, responding to the operation monitoring message according to the monitoring target device as confirmed, comprising:
• determining whether the monitoring device is the relay device or a far-end device associated with the relay device;
• in response to determining that the monitoring target device is the relay device, obtaining operation information as requested by the operation monitoring message, as a response to the operation monitoring message
• in response to determining that the monitoring target device is the far-end device associated with the relay device, sending a second operation monitoring signal through a third optical port of the relay device, the second operation monitoring signal carrying the operation monitoring message.
