Before acquisition module 301 acquires feedback channel data, acquisition module 303 starts offline DTP for obtaining master control Instruction, and master control is started into offline DTP instructions and is supplied to pause module 304, wherein, master control starts in offline DTP instructions at least Tested length, feeder line description information, feedback channel mark and the receiving channel mark of configuration frequency, feeder line including feeder line.
The configuration frequency of feeder line includes the initial frequency of feeder line and the termination frequency of feeder line.
Suspend module 304, it is legal for working as the information in the offline DTP instructions of master control startup, and testing mutual exclusion with DTP Business in master control when starting the highest priority of offline DTP instruction, suspend the processing of other business datums, and inform startup mould Block 305 is paused to handle other business datums, other business datums include testing less than DTP test prioritizations and with the DTP The corresponding data of business of mutual exclusion, DTP tests are used for the position of fault inspecting.
After pause module 304 suspends the processing of other business datums, starting module 305 starts DTP tests.
It is understood that starting module 305, before DTP tests are started, correction verification module 313 verifies master control and starts offline Whether the information in DTP instructions is legal, and when whether the information that master control starts in offline DTP instructions is legal, pause module 304 is sentenced It is disconnected to be with DTP test same priorities and/or higher than the mutual exclusion business (business with DTP test mutual exclusions) of DTP test prioritizations It is no to be carrying out.I.e.：It is carrying out when there is the mutual exclusion business with DTP test same priorities and/or higher than DTP test prioritizations When (priority that i.e. master control starts offline DTP instruction is not highest), then when being tested with preferential with DTP waiting in the predetermined time Grade and/or higher than DTP test prioritizations business processing complete, pause module 304 pause less than DTP test prioritizations and with The DTP tests the business of mutual exclusion, then informs that starting module 305 is paused and handles other business datums, so as to starting module 305 Start the business of DTP tests；When testing same priority and/or higher than DTP test prioritizations with DTP within such scheduled time Business do not handle completion, starting module 305 does not start DTP tests.It is understood that such scheduled time for etc. It is pending to test same priority and/or the business hours higher than DTP test prioritizations with DTP.It is predetermined that the present invention does not limit waiting The specific time range of time, such as 5s etc..
When being carrying out there is no the mutual exclusion business with DTP test same priorities and/or higher than DTP test prioritizations, Pause module 304 directly suspends the processing of other business datums and starting module 305 starts DTP tests.
Further, after starting module 305 starts DTP tests, initialization module 306 is to RAM module 310 and FDR Module 302 is initialized respectively.And state-query module 307 carries out state respectively to RAM module 310 and FDR modules 302 Inquiry, and the query result of RAM module 310 and FDR modules 302 is sent to and terminates module 308.
Wherein, data generating module 309, the information for being started according to master control in offline DTP instructions generate at least one set of Swept-frequency signal, and at least one set of swept-frequency signal is pre-stored in RAM module 310.
When data generating module 309 generates at least two groups of swept-frequency signals, there is same time between every group of swept-frequency signal Interval, i.e., data generating module 309 periodically generation swept-frequency signal.
Specifically, the tested channel feedback channel mark that data generating module 309 includes according to the offline DTP instructions of control startup Know corresponding feedback channel, receiving channel identifies the information of corresponding receiving channel, generates at least one set of swept-frequency signal, and will be every Group swept-frequency signal is transmitted to by local bus local bus in RAM module 310.

By this programme, while the efficiency for improving fault inspecting, compared with prior art in be only capable of inferring be base station, The problem of upper wire jumper, lower wire jumper and/or antenna break down, the present invention is by frequency domain point except the reflection that method calculates trouble point is prolonged The slow time according to the reflection delay time of trouble point, obtains trouble point to the distance eated dishes without rice or wine, so as to be accurately obtained trouble point Position.
With reference to the description in Fig. 3-Fig. 4, the present invention provides a kind of processing method of signal, and the executive agent of this method can be with For base station, the specific RRU in base station.As shown in fig. 6, this method specifically includes：
601, feedback channel data are acquired, pre-distortion is carried out to feedback channel data, obtains pre-distortion data, Feedback channel data are the data of the active inter-modulated signal in feedback channel coupling firing channel.
Wherein, transmission channel is the channel of active inter-modulated signal emitted outward, and feedback channel is in coupling firing channel Active inter-modulated signal channel.
602, receiving channel data are acquired, using pre-distortion data as reference data, are obtained from receiving channel data PIM spectral lines, the letter that the passive intermodulation signal and antenna that receiving channel data are generated for receiving channel reception by trouble point receive Number data.
Wherein, receiving channel is to receive leading to for the passive intermodulation signal generated by trouble point and antenna received signal Road.
603, PIM spectral lines and base reference signal are subjected to frequency domain point except method calculates the position of trouble point, calculated As a result, result of calculation includes trouble point to the distance eated dishes without rice or wine.
It can be the machine top opening end of transmitting swept-frequency signal wherein to eat dishes without rice or wine.
The processing method of a kind of signal provided in an embodiment of the present invention, with needing artificial upper station in the prior art and passing through Low intermodulation load is accessed, corresponding position of breaking down respectively to base station, lower wire jumper, upper wire jumper, feeder line and antenna carries out downlink Fictitious load, so as to the connection of investigation cable step by step, the problem of causing fault detection efficiency relatively low, is compared, this hair It is bright by acquiring feedback channel data and acquisition receiving channel data and being obtained according to feedback channel data and receiving channel data To PIM spectral lines；Then PIM spectral lines and base reference signal are subjected to frequency domain point except method calculates the position of trouble point, are counted It calculates as a result, result of calculation includes trouble point to the distance eated dishes without rice or wine, so as to improve the efficiency of detection failure.
Further, pre-distortion data in step 601 are active inter-modulated signal.
In the present embodiment, the RRU of base station is generated and is periodically emitted swept-frequency signal (ofdm signal) to cable to be measured. Since transmission channel has centainly non-linear, lead to active signal by the way that nonlinear active intermodulation can be generated after transmission channel Signal, having an impact for the reflection signal generated to trouble point in order to avoid nonlinear active signal, leads to the failure calculated Point is incorrect, so needing to fall the active inter-modulated signal correction of transmission channel by feedback channel.In the output of transmission channel The radiofrequency signal of mouth (before transmitting (Transport, Tx) duplexer) coupling part is to feedback channel, then by the feedback of acquisition Channel data carries out pre-distortion.
Further, in step 602, receiving channel data include the reflected signal in trouble point and other letters Number.After transmission channel signal is by trouble point, it may occur that the broadening phenomenon of frequency spectrum, the inter-modulated signal partial frequency spectrum of broadening, which is fallen into, to be connect Receive the corresponding reception frequency range of channel, drop into receive frequency range signal can receive (Receive, Rx) duplexer because being reflected into thus It falls into receiving channel, is received after channel reception, receiving channel data are acquired, then by receiving channel data and predistortion Processing data are filtered frequency conversion, inhibit non-intermodulation frequency point signal (namely active inter-modulated signal), extract the PIM spectrums of needs Line.
That is, since passive intermodulation signal is used for the accurate location of fault inspecting, and include in receiving channel data Source inter-modulated signal and passive intermodulation signal.Therefore it needs with the predistorting data (active inter-modulated signal) obtained in step 601 for ginseng Data are examined, frequency-conversion processing is filtered to receiving channel data, obtains passive intermodulation signal, i.e. PIM spectral lines.
It is further to note that in order to ensure the consistency of data, the feedback channel data that are acquired in the present embodiment and The receiving channel data of acquisition are the signal in same group of swept-frequency signal.
Further, in step 603, frequency domain point is carried out by PIM spectral lines and base reference signal and removes method trouble point Position, specifically include：
In formula (1), L is trouble point in cable from eating dishes without rice or wine with a distance from the machine top opening end of swept-frequency signal (transmitting), Peak is through analog-digital converter (Analog to by PIM spectral lines and base reference signal by the direct current signal that frequency mixer exports Digital Converter, ADC) sampling after, carry out Fast Fourier Transform (Fast Fourier Transformation, FFT the integer corresponding to peak point obtained after)；NfftSampling number when being progress FFT transform in a cycle is (generally 1024th, 2048,4096 etc.)；f1Initial frequency for swept-frequency signal；f2Termination frequency for swept-frequency signal；VPFor swept-frequency signal Wave velocity.When the frequency step of swept-frequency signal is Δ f, then Nf=Δ f (f1-f2)…………………(2)
The maximum fault measuring distance L obtained using this methodMAX：
For example, NfIt is 21, Nfft1024 are taken, the start-stop frequency of test is 1920~1980MHz, i.e. f1For 1920MHz, f2For 1980MHz.The frequency step of swept-frequency signal (ofdm signal) is 1MHz.It is calculated by above formula, trouble point L is 2.9 ± 0.146 meter.
Trouble point maximum measures length L at presentMAXIt it is 120 meters, in order to ensure the correctness measured, the value of system is 100 Rice.So the range of measured value normally should be within 0~100 meter.
It is assumed that the upper wire jumper of antenna-feeder system is 5 meters, lower wire jumper is 5 meters, a length of 90 meters of feeder line, connection such as Fig. 1 of antenna feeder It is shown, then it is 2.9 meters according to result of calculation L above, then corresponding trouble point is on lower wire jumper.It is and empty in lower wire jumper distance Position at 2.9 ± 0.146 meters of mouth.
Further desirable for explanation, PIM spectral lines include the corresponding passive intermodulation signal of at least one set of swept-frequency signal, and one Feedback channel data and receiving channel data in group swept-frequency signal correspond.
Specifically in step 603：
When PIM spectral lines passive intermodulation signal corresponding including one group of swept-frequency signal, by PIM spectral lines and base reference signal Frequency domain point is carried out except method calculates the position of trouble point, obtains result of calculation.
An at least PIM spectral line is obtained after receiving channel data are filtered, RRU can therefrom extract more A PIM spectral lines.Preferably, RRU extracts a wherein PIM spectral line.
When PIM spectral lines passive intermodulation signal corresponding including at least two groups of swept-frequency signals, every group in PIM spectral lines is swept The corresponding passive intermodulation signal of frequency signal is overlapped, and obtains superposition PIM as a result, will superposition PIM results and base reference signal Frequency domain point is carried out except method calculates the position of trouble point, obtains result of calculation.As can be seen that by least two groups of swept-frequency signals Corresponding passive intermodulation signal is overlapped, and can reduce the error rate of result of calculation.
Further, before step 601, this method can also include：
Obtain master control and start offline DTP instruction, master control start included at least in offline DTP instructions feeder line configuration frequency, Tested length, feeder line description information, feedback channel mark and the receiving channel mark of feeder line.When master control starts offline DTP instructions In information it is legal, and when the master control described in the business of mutual exclusion starts the highest priority of offline DTP instruction, suspend other The processing of business datum simultaneously starts DTP tests, other business datums include less than DTP test prioritizations and mutual with DTP tests The corresponding data of business of reprimand, DTP tests are used for the position of fault inspecting.Wherein, RRU starts offline DTP to master control and instructs In information carry out legitimacy verifies include information in information and memory space (such as RAM module) during RRU instructs DTP into Row compares, and when the two information is consistent, illustrates that the information that master control starts in offline DTP instructions is legal.
Wherein, it is what is issued by the BBU in base station that master control, which starts offline DTP instructions,.When BBU receives the maintenance by base station During the detection faulting instruction that platform issues, the configuration parameter included according to the detection faulting instruction starts offline to generate master control DTP is instructed, and the master control is started offline DTP instructions and passes to RRU.Detection faulting instruction is used to indicate base station and opens DTP surveys Examination.Initial frequency, the termination frequency of feeder line, the feeder line description of configuration feeder line can be included by detecting the configuration parameter in faulting instruction Information, the tested length of feeder line, transmission channel mark, feedback channel mark and receiving channel mark etc..
After RRU receives the offline DTP instructions of master control startup, before DTP tests are started, RRU verification master control startups The legitimacy of information in offline DTP instructions.
When master control start the information in offline DTP instruction it is legal when, judge whether to have in the business handled and be higher than DTP tests the mutual exclusion business of service priority.It is pre- when waiting for when there is the mutual exclusion business higher than DTP test service priority When the mutual exclusion business higher than DTP test service priority is completed in processing within fixing time, suspend the processing of other business datums And start DTP tests.The still untreated mutual exclusion business for completing this higher than DTP test service priority within the waiting predetermined time When, do not start DTP tests, that is, terminate DTP tests.When there is no higher than DTP test service priority mutual exclusion business when, Suspend the processing of other business datums and start DTP tests.
What deserves to be explained is when RRU starts DTP tests, RRU deletes carried service district information, and to outside upper Report resource unavailable.Here resource refers to the required resource of RRU processing business.
Likewise, being not limited to the range of predetermined time in the present invention, the usual predetermined time embodies the validity of DTP tests, Under the premise of DTP tests are effective, RRU can wait for the mutual exclusion business processing higher than DTP test service priority to complete it Just start DTP tests afterwards.
Further, after RRU starts DTP tests, this method further includes：
To RAM module and FDR modules are initialized respectively and status inquiry.When the continuous-query in the first pre-determined number When state at least one of RAM module and FDR modules module is unavailable, DTP tests are terminated.Wherein, RRU is inquired The state of RAM module and FDR modules specifically includes：It is corresponding for the parameter of detection and FDR modules pair that RRU obtains RAM module The parameter for detection answered, then by acquisition for the parameter of detection and corresponding RAM module and the scheduled mark of FDR modules Accurate value is compared, when the corresponding parameter and FDR modules for detection of RAM module it is corresponding for the parameter that detects respectively with Corresponding scheduled standard value is consistent, and the state for illustrating RAM module and FDR modules is available, and vice versa.
RAM module is at least one set of swept-frequency signal that prestores.FDR modules test corresponding trouble point for obtaining the DTP Position.It is understood that RAM module and FDR modules are present in RRU.
The present invention does not limit the concrete numerical value of the first pre-determined number equally yet, and the priority tested according to DTP determines the The concrete numerical value of one pre-determined number.Such as in a base station when priority that setting DTP is tested is higher, the value of the first pre-determined number compared with Greatly.Such as 3 times, 4 times or 5 times.When the priority that setting DTP is tested in a base station is relatively low, the value of the first pre-determined number can be 1 It is secondary or 2 times.
Further, as RRU in the first pre-determined number the state of continuous-query to RAM module and FDR modules be can Used time tests corresponding feedback channel, receiving channel, RAM module to DTP and enables.According to the initial frequency of feeder line and feeder line Terminate frequency configuration local frequency.
After local frequency is configured in RRU, start to perform step 601.It is understood that step 601- steps 603 are held Concrete operations of the capable operation for DTP tests.
Further, after step 603, this method further includes：
