Brief description
The full-automatic unmanned satellite telemetry monitor supervision platform structural representation on duty of Fig. 1 present invention.
The full-automatic unmanned satellite telemetry monitor supervision platform data processing method flow chart on duty of Fig. 2 present invention.
Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in further details.
As shown in figure 1, full-automatic unmanned satellite telemetry monitor supervision platform on duty, this platform includes: demodulator, regulator,
Remote measurement transmitting server, data base, memorizer, computer client and mobile client；Telemetry is sent by monitored satellite
To demodulator, by demodulator recovering signal, make after data delay complete reading, to reach remote measurement transmitting clothes via regulator
In business device.Satellite has the transfer rate of oneself, and the speed due to satellite data transmission is not particularly stable, and leading to can not be according to former
The speed transmission that the fixation per second having regulation receives 8 frames or receives 1 frame every 125 milliseconds.According to how many data per second and
Frame length calculates that needs are per second to take 8 frames, in order to avoid occurring specifically taking less than 8 frames or take next time 8 frames to also have residue frame
Situation about not taking, by regulator, actually one queue, first allows all of frame enter team in order, through certain time
Afterwards it is ensured that inside queue the number of frame be at least 8.Take 8 frames every one second, queue, by take away 8 frame deletions, has other frames
Enter successively in queue, therefore only need to ensure to go inside queue, to take 8 frames every one second.Postpone to read for several seconds by regulator
Data may insure the accuracy of data.Described remote measurement transmitting server all stores the telemetry receiving to memorizer
In, the path of telemetry is stored to lane database simultaneously；Remote measurement transmitting server is carried out after dissection process to telemetry
Send to data base, contrasted with the configuration information that sets in data base in advance, and abnormal information is also shown in computer
Client and mobile client are reminded, and described computer client and mobile client are by amended configuration information typing number
According in storehouse.Configuration information is the document being provided according to expert, by the parameter information of satellite, such as parameter format, parameter name, frame generation
Number, in the input database such as frame length, processing method, coding type, dimension and remark information.Parsing is telemetry to be carried out point
Analysis is processed, and applies remote measurement abnormal ranges and respective rule, completes the threshold decision of data, association judges and extremely judges, and by
Analysis result is shown in computer client and mobile client, and input is the telemetry receiving, and on the one hand output be distant
Survey the result after parameter calculates or state；On the one hand it is abnormal information and Warning Sign.Detailed process is as follows: by regulator
After getting a frame, first determine the synchronous head of frame, the document according to expert's offer, come the classification of judgment frame, judges that this frame corresponds to
Which frame under which classification, then goes to read the related configuration file of this frame in data base.Understood by configuration file and connect
To data from the beginning of which position, altogether across how many positions be this telemetry value corresponding to which parameter in satellite,
The coding type being given according to configuration file and dimension calculate real telemetry value, and real telemetry value is given by expert
Unconventionality expression formula judged, judge whether that abnormal conditions occur, if abnormal conditions occur be shown in expert's mobile phone terminal in time
And find solution.Expert gives the requirement that the unconventionality expression formula of parameter and frequency of abnormity count: for different parameters,
By parameter, under different working modes, abnormal parameters value scope defines exception；Frequency of abnormity counting is that different parameters continuously go out
The counting of existing abnormal number of times.For different parameters, the requirement abnormal counting how many times continuously is different: the possibility having
Occur once extremely being accomplished by notifying expert to be processed, have abnormal several times reinforming at expert may continuously
Reason.
The data processing method of full-automatic unmanned satellite telemetry monitor supervision platform on duty, the method comprises the steps:
Step one, preliminary preparation, by the configuration information input database of satellite telemetry parameters, we will not be all
Extremely it is stored in data base.Only record telemetry parameter configuration information in data base, tele rcording (comprises telemetry rule file
Path), analysis result.The benefit doing so is to avoid data base to preserve telemetry identical and useless in a large number, prevents data
Database data is excessive.Data is carried out with rule and deposits in memory, conveniently telemetry is carried out with secondary parsing and analyzes.
Step 2, defines remote measurement extremely by specific specialists using expression language, and sets exception level.Using expression formula
Language, when definition is abnormal, can be not limited to only judge the codomain of single parameter, expression formula can associate multiple parameters, root
Judge whether some parameter is abnormal according to the currency of other specification, and can be according to time or the related association of frame group definition
Valid parameter value.Abnormal in two kinds of situation by expression language definition, one is individually to judge parameter, by entering with expert
Row agreement judging parameter whether in the range of normality threshold, if do not meet within normal range again frequency of abnormity count carry out different
Often early warning is simultaneously shown in platform and app end；Two is to judge two or multiple parameters, parameter 1 by carrying out agreement with expert
It is divided into different mode, the threshold range of parameter 2 is different it is therefore desirable to this two parameters are put together in different modes
Consider, individually consider that the threshold range of parameter 2 is inaccurate.Situation 1: define communication link status, provided according to expert
Document, if being 1 by the telemetry parameter value obtaining after parsing, normally；Otherwise abnormal, and this is pushed to extremely platform with
Expert app end.Define solar facula gray value, according to the unconventionality expression formula of expert's definition, [0,1023] is the normal model of parameter value
Enclose.If passing through the parameter value obtaining after parsing not within normal range, frequency of abnormity counts to be increased once, if abnormal conditions
Continuous occur, and frequency of abnormity counts to be increased once；If under subnormal, reset.When frequency of abnormity is counted as 3, this is abnormal
Situation pushes to platform and expert app end.Situation 2: define telemetry parameter satellite present mode and output voltage.Current in satellite
Pattern parses number biography mode of operation and gets off to judge output voltage whether within normal range [26,29], in satellite present mode
Whether parse photograph mode of operation gets off to judge output voltage within normal range [25,28].If not within normal range and
Shi Jinhang pushes.Define telemetry parameter satellite current location and sunlight temperature.Satellite current location be on the sunny side when sentence
Whether whether disconnected sunlight temperature is not more than 300 DEG C, otherwise judge sunlight temperature in the range of [0,100].If
Not in this range, then frequency of abnormity counts increases once the telemetry parameter value parsing, if abnormal conditions continuously occur, meter
Number is further added by once；If under subnormal, reset.When frequency of abnormity is counted as 5, some instruments of satellite will be unable to use, this
For abnormal conditions
Real-time reception satellite telemetry, can receive many stars telemetry simultaneously, put into spy after telemetry frame is classified
Determine satellite telemetry resolution unit to be parsed.While parsing telemetry, using the thread scheduling principle of thread pool, to every
The value of individual parameter carries out abnormal judgement.During accepting satellite exception, ratio is larger in a large number for data, and parameter value is many, and
The value of each parameter is ceaselessly changing, so distributing multiple threads data numerous real-time ginsengs using the mode of thread pool
Number.
Step 3: the telemetry parameter parsing value is shown to staff interface, all telemetry parameters is included simultaneously
Abnormal conditions and following abnormal conditions are moved towards encryption and are pushed to core expert's mobile device.Realize unmanned abnormity early warning work(
Energy.Reach one side analysis judgment abnormal while by abnormal show the prompting function in mobile terminal.
