Whether the BSP 104 is additionally operable to continuously detect 3 times in the corresponding fixed control word location of the optical port 105 and receives
To the particular sequence, if 3 all detections receive the particular sequence, the RRU 10 is in optical fiber from ring status.
When the self-checking system of RRU hardware 101 carries out self-test, physical connection (as shown in Figure 1) is first carried out, the physics connects
The step of connecing includes：
Step 201, the RRU is powered off；
Step 202, the both ends of the optical fiber are connected respectively to the transmitting-receiving two-end of the optical module, realize the RRU's
Optical fiber is from ring.
In different occasions, during physical connection, the RRU can be as needed with the BBU, and selection disconnects or not
Disconnected, such as when being detected before the RRU opens station, the RRU and BBU can not have to disconnect.In addition, the day of the RRU
Crevasse can also select to be connected with a load or miniature antenna as needed, described such as when being detected before the RRU opens station
RRU day crevasse is connected with a load or miniature antenna.
The physical connection is being carried out, is realizing that the optical fiber of the RRU from after ring, further performs the optical fiber of the RRU
From ring detection process, it is specially：
Step 301, under FDD (FDD, Frequency Division Dual, abbreviation FDD) standard, institute is detected
State whether optical port has light, while detect whether that the alarm of LOF losing locks or the unlocked alarm of clock chip occurs, if the optical port has
Light and exist LOF losing locks alarm or the unlocked alarm of clock chip among one kind, illustrate lock optical port speed discomfort
Should, now need to start the self adaptive flow of the speed of the optical port；
Step 302, a particular sequence and a frame head are sent to the optical port in the fixed control word location of sendaisle；
Step 303, whether the corresponding fixed control word location detected in the optical port receives the particular sequence, if receiving
To the particular sequence, then it is assumed that the RRU is in optical fiber from ring status.
Referring to Fig. 3, the self adaptive flow of the speed for optical port described in step 301, the self adaptive flow includes：
(1) the RRU initialization, is first carried out adaptively with 1G speed, if adaptively, it is adaptive to carry out periodic rate
Should；
(2) it is if not adaptive, carried out with 2G speed, if adaptively, it is adaptive to carry out periodic rate；
(3) it is if not adaptive, carried out with 3G speed, if adaptively, it is adaptive to carry out periodic rate；
(4) it is if not adaptive, carried out with 6G speed, now first configure the parameter of the SERDES, then carry out detection light
Fibre is from ring status, then judges whether adaptively, if adaptively, it is adaptive to carry out periodic rate；
(5) it is if not adaptive, carried out with 10G speed, it is now in spite of adaptive, then adaptive into periodic rate
Should.
When configuring the SERDES parameters, whether normal, then detect the CPRI if need to first detect the SERDES states
Whether state is synchronous, it is understood that there may be SERDES state-detections are normal, but the abnormal situation of CPRI state-detections, now institute
State BSP and reconfigure the SERDES, and detect the SERDES states, then detect the CPRI synchronous regimes, that is, circulate past
It is multiple to carry out until the rate-matched of the transmitting-receiving port of the optical module.
Referring to Fig. 4, detected for the optical fiber in step 302, step 303 from ring testing process, the optical fiber from ring
Flow includes：
(1) particular sequence is sent to the optical port in the fixed control word location of sendaisle；
(2) frame head is sent to the optical port in the fixed control word location of sendaisle；
(3) 1s is waited, if detecting the particular sequence in the optical port, the RRU is in optical fiber from ring status, continuously
Detection 3 times, the cycle detected every time is 1s, if being not at optical fiber from ring status, is continued waiting for；
(4) if continuously detection 3 times, the RRU from ring status, then sets optical fiber to trigger institute from ring mark all in optical fiber
State RRU hardware and carry out self-test, after self-test terminates, exit the RRU hardware and detect state from ring；
(5) if continuously detection 3 times, the RRU then cancels not all in optical fiber self-test state and sends particular sequence and described
Frame head gives the optical port, exits the RRU hardware checks state.
The optical fiber from ring testing process, due to the RRU do optical fiber from ring at the time of it is uncertain, it is necessary to which the RRU is soft
Part can detect and judge whether the RRU is in optical fiber from ring status in any situation, and the RRU is in optical fiber from ring-type
The information received during state is that the data progress loopback that the RRU is sent obtains, and is not from the information that the BBU is issued, because
This makes the FPGA send a particular sequence to the optical port in the fixed control word location of sendaisle by the BSP,
And the particular sequence is that the BBU can not be sent, the RRU softwares only need to monitor the corresponding fixed control of the optical port
Word location processed receives the particular sequence, it is possible to judges whether the RRU is in optical fiber from ring status.
Again because under FDD standards, control word has carried out CRC (CRC, Cyclic in the RRU
Redundancy Check, abbreviation CRC) verification, cause optical fiber from ring when the particular sequence can not normally detect, so in order to
The frame head is sent to the light, it is necessary to configure can correctly detect the particular sequence in the optical port under ring status
Mouthful, and the frame head is test frame head.
Referring to Fig. 5, the optical fiber of the RRU, from after ring detection process, the RRU is in optical fiber from ring status, then touches
Send out RRU hardware described and carry out self-test, when the RRU hardware carries out self-test, carried out item by item according to the fixed RRU hardware orders
Self-test, item by item the order of self-test include：--- --- DAC interfaces --- receive ADC interface --- to power supply for board clock and local oscillator
Feeding back ADC interface, --- --- downlink is flat for downlink gain --- the transmitting ATT linearities --- for FPGA functions
Spend --- standing wave --- power amplifier switch --- circulator --- uplink gain.
(stayed provided with RUN lamps (green light), OPT lamps (green light), ACT lamps (green light), ALM lamps (red light) and VSWR in the RRU
Bob, Voltage Standing Wave Ratio, abbreviation VSWR) lamp (red light), in process of self-test, only when previous item
When testing result is normal, the detection of the next item down is just carried out, when each single item is all normal, OK is returned, lights RUN lamps, described
OPT lamps and the ACT lamps；If wherein have a testing result abnormal, Err is returned, lights the ALM lamps and RUN lamps.
The self-detection result data finally returned to are saved in the FLASH.During self-test, the light on and off situation of the indicator lamp can
To set, in the present embodiment, all indicator lamps flash in a manner of 0.5s goes out, 0.5s is bright.
Judgement to the RRU hardware checks result has two ways,
(1) judged by indicator lamp, when RRU lights the RUN lamps, the OPT lamps and the ACT lamps, illustrate institute
State the inside fault-free of RRU hardware；When lighting the ALM lamps and RUN lamps, illustrate that the inside of the RRU hardware is faulty.
(2) by reading the self-test journal file in the FLASH, the detection knot of the RU hardware checks each single item is checked
Fruit.
In order to avoid RRU described in erroneous judgement causes in optical fiber not stopping self-test repeatedly under the conditions of ring, the RRU is software defined
The self-checking function number of run of process of self-test is no more than 10 times, if during more than 10 times, manually deleting the FLASH
In self-detection result reactivate 10 self-tests.
After self-test terminates, remove and connect the optical fiber, the RRU resets, and exits the RRU hardware checks state.
