Storedtestingandmeasuringisakindofdynamictesttechnologywhereinmicrodatarecordinggaugeisembeddedintheobjecttobemeasuredintheconditionthatthereisnoorallowableeffectonit.Theinformationiscollectedandmemorizedatthespotinrealtime.Therecordingdeviceisrecollectedandcomputerisusedtoprocessthemeasuredinformation.Thekeytorealizedynamicstoredtestingandmeasuringliesindevelopingofstoredtestingandmeasuringsystem(STMS)thatcanworknormallyinthetestingenvironmentandhaveeithernoeffectontheobjecttobemeasuredortheeffectisintheallowablerange.

Thedefinition,character,applicationfieldandbasicelementsarestudiedsystematically.Theoverallreviewofresearchanddevelopmentsituationinhomeandoverseaisgiven.DuringPh.Dcandidatestudyingperiod,theauthorhaspresidedoverthedevelopmentofdata-recordingdevicesusedon60channelsdynamicdatatestingandmeasuring(TM)duringatmosphere-reenteringofintercontinentalballisticmissile(ICBM)warhead,intelligentmissileblockboxusedondynamicdata-recordingofcertainheavyanti-tankmissileflight,anti-warshipmissilesliptrackflightfusedatatestingandmeasuringsystem,cannonshootmissileballcartridgeflightdata-recordingdevice,STMSofinneroverloadingcurveofpenetrativepillandballchamber.Basedontheseexperiencestheauthoranalysesthoroughlytheinnerrulesoftestingandmeasuringtechnologyandsummarizethedesignconceptanddesignrulesinaphilosophicalview.ThedesignprinciplesthatcanconducttheengineeringpracticeofSTMareestablished,whichmakethedesignofSTMSoptimizedinalogicalandrationalway.

TheSTMSresearchedinthepapermainlyusedinthespecialenvironmentwiththefollowingattributes:

AftersystematicallystudyingmanyoftheSTMSexamples,thedesigntheoryandtenmicroscopicaldesignprinciplesofSTMSarepresented.Theyincluderealizabilityofworkingprinciple,recollectabilityoftestingandmeasuringdata,matchingand/orharmonizing,compatibility,environment-adaptability,reusingandcalibrationability,flexibledesign,modularizationdesign,optimizingandtrade-offoftechnologyschemes.TheconceptionofstatedesignofSTMSisfirstlypresented.Thebasicconceptions(forexample,STMSstate,statevariable,statespace,statenet,stateassembleandstatechain)aredefined,followedbystudyingofstateassemble,establishingofstatechainand/orstatenetdesignprinciplesandmethods.Further,theirapplicationscopeandtypicalapplicationsareillustrated.Thetimepowerfactortheoryandthemathematicsdescriptionofsystemstateanditstransformationarepresented.

ConsideringSTMSasaninformationtransmissionsystem,theinformationtransmissionmodelofitisestablished.Thetestingandmeasuringinformationflow,equivalentinformationtransmissionmodelandnoisemodelareanalyzed.Fromtheinformationtransmissionview,thesimilaritybetweenSTMSandShannoncommunicationsystemiscomparedtoestablishthetheorybasisforstudyingTMchannelbyapplicationinformationtheory.

Accordingtotheattributeofthemeasuredsignal,theTMrequirement,workingenvironmentandsoon,thebasicproblemsofSTMsamplingdesignareresearched.FourSTMsamplingstrategy(uniformitysampling,automaticsubsectionuniformitysampling,programmableself-adaptivesubsectionuniformitysamplingandself-adaptivesampling)arepresented.Thealgorithmofzeroorderandoneorderpredictableself-adaptivesamplingisintroducedindetail.Thesourceofsamplingerrorandthemethodtoavoiditareanalyzedandresearched.

Twokindsofsamplingsignalquantizers(uniformityandununiformity)arepresented.TheinformationratedistortionfunctionoftheuniformityquantizerandtheSNRalgorithmareestablished.Thesignalcapacityandmulti-channelinformationTMprincipleisresearched.ThealternativeprincipleofADCmulti-channeltransducerispresented.

(2)Foraddressgeneratorcomposedofserialcounter,thepropulsionofaddressisdonebytherisingedgeofWRsignal.(3)ReducingmemorysubsystemtransmissiontimeaspossibleasonecanormakingtheCMOSmemoryoperationduringtransmissioninvalid.

Basedonstudyoftheinformationcompressionprinciple,twoinformationcompressivestoringalgorithmsarepresented.Oneisthealgorithmoffinitespanerrorlimitationusedinrealtimedynamicdatacollecting.Thecomputersimulationshowsthatthealgorithmisveryeffectiveinreal-timedatacompressionandstorage(datacompressiveratioupto13.6andmemoryspacesaveupto92%).Theotherisdatamodelcompressivealgorithmbasedondynamicdatamodeling.ErrortolerencetechnologyandredundancydesignofSTMSarealsoresearched.
