6. An RRU device is characterized by comprising a sending unit, a judging unit, an alarming unit, a first processing unit and a second processing unit, wherein:
the sending unit is used for sequentially sending single tone detection signals corresponding to each physical sub-channel included in the RRU according to a preset sequence if the RRU channel is detected to be in fault, and stopping the sending unit until one of the physical sub-channels is judged to be abnormal according to the single tone detection signals;
the judging unit is used for taking the abnormal physical sub-channel as a fault physical sub-channel and judging that the reason of the RRU channel fault is RRU hardware fault;
the alarm unit is used for generating a first fault alarm message according to the fault reason of the faulty physical sub-channel and the RRU channel, and sending the first fault alarm message to a base station, so that the base station displays the first fault alarm message, and a fault handler can replace the RRU equipment according to the first fault alarm message;
the first processing unit is used for acquiring the reason for resetting the RRU last time if judging and knowing that each physical subchannel is not abnormal according to the single tone detection signal;
if the reason for carrying out RRU reset last time is judged and known to be not the RRU channel fault, carrying out RRU reset;
the second processing unit is used for acquiring an error rate corresponding to an IR link between the BBU if the reason for the RRU reset last time is judged and known to be RRU channel failure;
and if the error rate is judged to be larger than a second preset threshold value, determining that the reason of the RRU channel fault is an IR link fault, generating second fault alarm information according to the reason of the RRU channel fault, and sending the second fault alarm information to the base station, so that the base station displays the second fault alarm information, and the fault processing personnel can replace the optical fiber unit of the IR link according to the second fault alarm information.
