Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make intoIt is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementationExample.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative effortsAll other embodiment, shall fall within the protection scope of the present invention.
In embodiments of the present invention, server is O&M server, the i.e. server of field of traffic operation management.
Fig. 1 illustratively shows the process of a kind of starting method of fault detection, which can be by fault detectionStarter executes, which can be located in O&M server, can be the O&M server.
As shown in Figure 1, the specific steps of the process include:
Step 101, server obtains the historical time intervals of the upload data of terminal device in set period of time.
Step 102, the server optimizes the historical time intervals, and determines the historical time after optimizationFirst average value and first variance at interval.
Step 103, the server is according to the first average value and first variance of the historical time intervals after the optimization,Determine the time interval threshold value of fault detection；
Step 104, the server is if it is determined that the time interval that terminal device currently uploads data is examined greater than the failureThe time interval threshold value of survey, then carry out the fault detection of the terminal device.
In a step 101, since terminal device needs often to upload data to server, the available terminal of server is setThe standby time interval for uploading data judge the terminal device whether failure, therefore the available terminal device of server uploads numberAccording to time interval.
After the time interval for obtaining terminal device upload data, server is just it needs to be determined that the terminal device uploads numberAccording to time interval whether be greater than time interval threshold value.
Server can automatic maintenance terminal device threshold table and terminal device information table, terminal device and serverAlways linking status is maintained, using the adaptive operation production method of terminal device data acquiring frequency feature is based on, is arranged automaticallyTime interval threshold value.Specifically, server obtains the historical time intervals of the upload data of terminal device in set period of time.It shouldSet period of time can be empirically configured.Server is gone through according to the historical data in terminal device measurement period, extractionThe time interval that history data upload, it is assumed that collect N+1 data, calculate the time interval between data, generate data sequence, noteFor { Ti| i=1,2,3 ... N }, N is positive integer.
In a step 102, by step 101 obtain historical time intervals after, server to the historical time intervals intoRow optimization, and the first average value of the historical time intervals after calculation optimization.Specifically, in server deleting history time intervalMaximum and minimum, and the second average value and second variance of remaining historical time intervals are calculated, when according to remaining historyBetween the second average value for being spaced and second variance, delete the exception history time interval in remaining historical time intervals, complete pairThe optimization of historical time intervals.If Min-max is respectively T in the data sequence of above-mentioned historical time intervalsmin、Tmax, deleteAverage value is calculated after maximum and minimum, is denoted as TM.The following formula of calculation (1):
Wherein, TMFor the second average value of remaining historical time intervals, TiFor i-th of historical time intervals, TminFor historyMinimum in time interval, TmaxFor the maximum in historical time intervals.
Remove Tmin, TmaxAfterwards, the data sequence for reorganizing historical time intervals is { Ti| i=1,2,3 ... (N-2) }.The variance for calculating the data sequence of N-2 historical time intervals, is denoted as Tσ.Calculation formula is as follows:
Wherein, TσFor the second variance of remaining historical time intervals, TMFor the second average value of remaining historical time intervals,TiFor i-th of historical time intervals.
Calculate TσLater, according to the TσAnd TMDetermine data deviation, rejecting abnormalities data.Wherein k is coefficient, in programMiddle dynamic setting, to determine the ratio for rejecting data.Exception history time interval can be determined by formula (3).
|Ti-TM|≥k·Tσ…………………………(3)
Wherein, TσFor the second variance of remaining historical time intervals, TMFor the second average value of remaining historical time intervals,TiFor i-th of historical time intervals, k is coefficient, which is set by system dynamic.
First average value of the server based on the historical time intervals after optimization determines the historical time intervals after optimizingFirst variance.Last server determines that failure is examined according to the first average value and first variance of the historical time intervals after optimizationThe time interval threshold value of survey.
Specifically, assuming that the number for the historical time intervals deleted is m, the data sequence of historical time intervals is reorganizedIt is classified as { Ti| i=1,2,3 ... N-m-2 }, it is recalculated respectively according to formula (4) and formula (5) between the historical time after optimizingEvery the first average value and first variance.
Wherein, TM' for optimization after historical time intervals the first average value, TiFor i-th of historical time intervals.
Wherein, Tσ' for optimization after historical time intervals first variance, TM' it is the of the historical time intervals after optimizationOne average value, TiFor i-th of historical time intervals.
According to the Tσ' and TM' available fault detection time interval threshold value, specifically can be according to formula (6)To the time interval threshold value of the fault detection.
The formula (6) are as follows:
TG=Tm'+k'×Tσ'…………………………(6)
Wherein, TGFor the time interval threshold value of fault detection, Tσ' for optimization after historical time intervals first variance,TM' for the first average value of the historical time intervals after optimization, k' is coefficient, can be set according to data variance value dynamic.
Assuming that not uploading the time interval T of the terminal device of data currentlyd, work as TdWhen meeting formula (7), that is, determineWhen the time interval that terminal device currently uploads data is greater than the time interval threshold value of fault detection, the failure of terminal device is carried outDetection.
Td≥TM'+k'·Tσ'…………………………(7)
Wherein, TdThe time interval of data, T are currently uploaded for terminal deviceσ' it is the of the historical time intervals after optimizationOne variance, TM' for optimization after historical time intervals the first average value, k' is coefficient.
At step 104, server server carry out terminal device fault detection before, server also it needs to be determined thatThe detailed trouble information code of the terminal device whether active upload itself, if so, the terminal device itself can be determinedFailure no longer needs to the fault detection for carrying out terminal device.
If not receiving the detailed trouble information code of itself of terminal device active upload, server needs to carry out eventuallyThe fault detection of end equipment, specific:
Whether the server detection network equipment breaks down, and mainly by network adapter, into network, all-network is setPreparation send inspection to instruct, if the communication of all-network equipment is normal, it is determined that network apparatus in networks does not break down, otherwise, reallyDetermine the network equipment to break down in network.That is, server by utilizing network adapter, timing all-network device broadcastsInspection instruction is sent, the all-network equipment in network is detected.If the communication of all-network equipment is normal, it is determined that networkThe middle network equipment does not break down, otherwise, it determines the network equipment to break down in network.
Specifically, server, for any bar network link in network, the terminal device with the bottom of network link isStarting point, each network equipment into network link sends inspection instruction, until receiving feedback command.Server willThe network equipment of the next stage of the corresponding network equipment of feedback command is determined as the network equipment of failure to be confirmed.Server laterIf the feedback for the all-network equipment that the network equipment for not receiving the next stage of the network equipment corresponding with feedback command is connectedInstruction, then be determined as the network equipment to break down for the network equipment of failure to be confirmed.From the terminal device of bottom-layer network byLayer retrospect network state, diagnostic instruction is sent in a manner of poll, identification judgement is carried out to returning the result, traces back to always without reasonThe network equipment of barrier.
For example, as illustrated in fig. 2, it is assumed that network totally 5 layers of structure, it is assumed that network equipment C0 failure, under the network equipmentFor all-network equipment all in abnormal communication states, detection method is as follows:
First link: inspection sequence is E0, D0, C0, B0.Terminate after to normal network equipment B0.
Article 2 link: inspection sequence is E1, D0, C0, B0.Terminate after to normal network equipment B0.
Article 3 link: inspection sequence is E2, D1, C0, B0.Terminate after to normal network equipment B0.
Then other chain circuit detecting methods are same as above.
All communication abnormality network equipments under network equipment C0 reversely trace back to network equipment B0, and network equipment C0 is trueIt is set to the network link of failure to be confirmed.Each of the links testing result can navigate to network equipment C0 and break down, and meet allIt, i.e., can be with the net of failure to be confirmed after the mutual verifying of the normal network equipment of polyisocyanate after the breakdown judge state consistency of the network equipmentNetwork equipment is determined as the network equipment to break down.If the network equipment quantity under failed network device is greater than 100, to improveSpeed is traversed, then only judges the interlocking proofing state of 100 network equipments, shields the fault message of other network equipments.
By the above method reversely layer-by-layer multichannel diagnosis, parallel multi-thread various dimensions are counter to be deduced, with network equipment eventBarrier positioning is mutually authenticated, and shields the network equipment lower layer network equipment failure letter for having obtained verifying.
If network equipment failure reparation is completed, or is broken down without the network equipment, still can not receive on terminal deviceData are passed, then the source of failure may be data link failure or terminal equipment failure.
Server continues to determine whether data link breaks down, specifically, server into network data Layer it is allData communication services adapter sends test instruction, if the non-returned data of data communication services adapter, it is determined that data linkIt breaks down.Server is after judging no network link failure, the communication test thread of log-on data link, carries out data linkTroubleshooting.Test instruction is issued by server, sequentially returns to return data in each service adapter program of data plane.Such asFruit is abnormal, and the abnormal mark of modification data link table identifies the data communication services adapter fails of this data link, reportedBarrier.By the diagnostic method, failure can be accurately positioned to data communication services adapter, determine that data link breaks down.
If above-mentioned data link reparation is completed or no data link layer breaks down, and still can not be received terminal and be setIt is standby to upload data, then show the terminal device itself fail, can determine that the terminal device breaks down, notifies work peopleMember overhauls the terminal device.
Embodiment in order to preferably explain the present invention will describe the stream of fault detection by specific implement scene belowJourney.
In embodiments of the present invention, server is O&M server, the i.e. server of field of traffic operation management.
As shown in figure 3, the specific steps of the process comprises:
Step 301, O&M server obtains the time interval that terminal device uploads data.
Step 302, whether the time interval that O&M server judges that the terminal device obtained uploads data is more than between the timeEvery threshold value, if so, step 303 is transferred to, if it is not, being then transferred to step 301.
Step 303, whether O&M server judges terminal device active reporting fault code, if so, being transferred to step308, if it is not, being then transferred to step 304.
Step 304, the O&M server starting network equipment diagnoses thread.
Step 305, O&M server judge the network equipment whether failure, if so, step 309 is transferred to, if it is not, being then transferred toStep 306.
Step 306, O&M server log-on data Diagnosis of Links thread.
Step 307, O&M server judge data link whether failure, if so, step 310 is transferred to, if it is not, being then transferred toStep 308.
Step 308, O&M server determines that the terminal device breaks down.
