Source is filled in AxC58-59, and to arrange a base frame fixed byte A be that aging mode indicates to comprise and arranges the
The first character joint of 145 base frames indicates for 0x55 is denoted as batch aging and is broadcast to RRU at different levels to be aging
In.
Step 4, starts RRU to be aging, and initialization-104.
Initialization comprises initialization RRU optical interface, comprises control and management field and base band data for obtaining optical interface information.
Step 5, it is that aging mode of operation configures each passage AXC-105 that RRU obtains mode of operation.
The first character joint that RRU obtains mode of operation to be aging mode of operation be inquiry the 145th base frame is 0x55; Configure each passage AXC for being China Telecom public network D frequency range (2635M-2655M) according to network, standard is TD-LTE standard, and port number is two passages, and collocation channel one and passage two all obtain AxC0-AxC7 base band data.
Step 6, RRU collocating uplink, descending, feedback link-106.
Up, descending, feedback three links of configuration RRU two passages are that the bandwidth of configuration two passages three links is 20M, centre frequency is 2645M, and configuring two passage downlink radio frequency delivery outlet power outputs is 43dBm.
Step 7, RRU enters aging mode and starts RRU status query task inquiry RRU state-107.
The aging mode of RRU is off-order mode, do not start IR interface protocol interaction flow, startup RRU status query task inquiry RRU state comprises two channel power values of inquiry RRU and two channel alarm states---alarm status comprises power supply class alarm status, clock class alarm status, up-downgoing and feedback link alarm status, board temperature classes alarm status and dry contact class alarm status---and be saved in each state parameter.
Step 8, arranges base band data transceiver by commissioning examination serial ports of computers and starts inquiry RRU state task-108 at different levels.
Step 9, inquire about RRU state task at different levels order according to the startup that commissioning examination serial ports of computers issues, data collector enters cyclic query RRU state at different levels flow process-109.
Data collector cyclic query RRU at different levels state flow process comprises any N level RRU state-110 of inquiry, it is N level RRU ID-111 that data collector arranges a fixed base frame fixed byte B, it is RRU state-112 at the corresponding levels that N level RRU arranges another string bit of this fixed base frame, and to arrange this fixed base frame fixed byte B be N level RRU ID-113 simultaneously, data collector gets N level RRU state information and preserves-114, judge agingly whether terminate-116, terminate then to enter step 10, otherwise reenter step 9 execution inquiry next stage RRU state flow process.
Data collector arranges a fixed base frame fixed byte B, and the second byte that to be N level RRU ID be arranges the 145th base frame is N-1, N level RRU recognizes as inquiring about state information at the corresponding levels, RRU is according to shown in Fig. 3, the up optical link control and management field bit0-bit127:bit0-bit7 filling the 145th base frame fills RRU each channel radio frequency output full power value 1LSB and represents 1dBm, it is RRU ID at the corresponding levels that bit8-bit15 keeps consistent with descending optical link control word, the bit16-bit111 altogether every 12bit of 96bit represents a channel power value, represent 8 channel power values altogether, front 8bit represents integer power, rear 4bit represents decimal power, 1LSB represents 1/16dBm, during less than 8 passages, non-filling channel bit fills with default value complete 1, bit112-bit127 represents 16 kinds of alarm status information of RRU, 0 represents alarm, 1 represents normal.The present embodiment is 43 for filling bit0-bit7, bit8-bit15 is N-1, bit16-bit27 is passage 1 performance number, bit28-bit39 is passage 2 performance number, bit40-bit111 is complete 1, bit112-bit127 is that filling comprises power supply class alarm status, clock class alarm status, on, descending and feedback link alarm status, board temperature classes alarm status and dry contact class 5 class totally 16 kinds of alarm status information, be specially: RRU input power is monitored, power failure alarm, the failure of RRU power-on self-test, RRU optical fiber recovered clock is monitored, the alarm of local oscillator losing lock, the alarm of RRU internal clocking losing lock, data feedback channel fault warning, the fault warning of data feedback channel LNA, down going channel fault warning, the fault warning of down going channel power amplifier, lower line output owes/overpower alarm, descending standing-wave ratio alarm, the alarm of power amplifier excess temperature, the alarm of board excess temperature, external status, the alarm of RRU lightning-protection module, totally 16 kinds of alarm status information.Data collector is saved in the file of corresponding RRU ID after getting related status information, judge aging successful or failed foundation as step 10.
In this step, adjust test computer by serial ports real-time query level or multistage RRU state-117, when base band data transceiver receives certain level of inquiry or multistage RRU state, obtain certain level or multistage RRU state information-115, and message is printed to serial ports-118; By commissioning examination serial ports of computers machine, aging the finish command-119 is set, the aging end mark of base band data transceiver set at the end of aging, judge aging at the end of exit cyclic query RRU state at different levels flow process and enter step 10.
Step 10, judges aging RRU success at different levels or failure-120 according to preservation RRU state information at different levels, and ageing results is printed to serial ports-121.
Successively the performance number of each RRU and alarm status are judged, whether agingly successfully enter follow-up test or unsuccessfully enter the subsequent maintenance stage---judge that whether the present embodiment N level RRU is successfully, traveling through each each channel power value more than 43 ± 1dBm is no more than 10% of cyclic query total degree at 43 ± 1.5dBm with indegree, and performance number is within 43 ± 1.5dBm, and 16 kinds of alarm statuses add up no alarm and are judged as aging success, otherwise be judged as aging failure---and ageing results at different levels is comprised aging successful or aging failed and judge failed foundation print to serial ports, this batch aging situation is checked for tester.
Step 11, aging end-122.
Above-described specific embodiment illustrates the present invention, but does not limit scope of the present invention.If to various possible equivalent change of the present invention or replacement, and change and replace all should belong to the claims in the present invention and equivalent technologies thereof protection range within.
