Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouchedThe specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Fig. 1 is the method for the speed of the adjusting simulation process provided according to an embodiment of the present disclosure, and this method canTo be applied to time server (that is, time server in analogue system).This method may comprise steps of.
In a step 11, in response to receiving control instruction, message is sent to each emulation module according in simulation processFirst frequency, respectively determine to each emulation module send message second frequency.
Firstly, being briefly described to time server, emulation module and communication between the two.The disclosure is mentionedIn the method for confession, time server is added in analogue system, can implement virtual time in entire analogue system.ExampleGround, the virtual time can be identical as the real time, alternatively, the virtual time can be different from the real time.In analogue systemComprising at least one emulation module, emulation module is configured as completing the corresponding artificial tasks of the emulation module, wherein emulation mouldBlock is after receiving sometime stamp, the achievable artificial tasks corresponding to the timestamp.In simulation process, time serverIt can be communicated with emulation module, to determine the emulation module of addition time cycle, determine that the artificial tasks of emulation module are completeAt situation, determine the emulation module in time departure period.Time server is stored with the synchronous list of a cycle, for recordingThe emulation module of time cycle is added.After time server receives the addition time cycle request of emulation module transmission, it will useIt is added in cycle synchronisation list in the information (for example, ID of emulation module) for indicating the emulation module, while to the emulation mouldThe block transmission addition period receives the response, then the emulation module is successfully joined the time cycle.Time server receives emulation moduleAfter the time departure periodic request of transmission, the information (for example, ID of emulation module) of the emulation module will be used to indicate from the periodIt is deleted in synchronous list, while leaving the period to emulation module transmission and receiveing the response, then emulation module success time departurePeriod.In simulation process, time server can to emulation module recorded in cycle synchronisation list send message (for example,Instruction), timestamp can be carried in the message, so that corresponding emulation module completes the artificial tasks for corresponding to timestamp,If also, emulation module completes a certain artificial tasks, can send task to time server and complete message, then, Time ServiceDevice would know that the artificial tasks of the emulation module are completed.It should be noted that emulating mould in the method provided by the disclosureBlock all refers to emulation module present in cycle synchronisation list, this is hereinafter not repeated to illustrate.
Wherein, emulation module is when sending the request of addition time cycle to time server, also simultaneously to time serverSend set of frequency required for the emulation module, in simulation process, time server then on the basis of the set of frequency, toThe emulation module sends message, under initial situation, that is, simulation process speed be not conditioned in the case where, in step 11The corresponding first frequency of emulation module can be identical as set of frequency required for the emulation module.It should be noted that byIt is different in the set of frequency of each emulation module, so time server sends the frequency of message to each emulation moduleAlso it is different, that is to say, that each emulation module corresponds to the first frequency of oneself, to each imitative described in step 11True module sends the first frequency of message, is to emulate according to the corresponding first frequency of each emulation module to corresponding in factModule sends message.Illustratively, if there are three emulation module (module 1, module 2 and module 3) modules, and the time cycle is added altogether, andThe corresponding first frequency of module 1 is 6Hz, and the corresponding first frequency of module 2 is 3Hz, and the corresponding first frequency of module 3 is 1Hz, thenTime server with the frequency of 6Hz to module 1 send message, with the frequency of 3Hz to module 2 send message, with the frequency of 1Hz toModule 3 sends message.
Illustratively, time server can the set of frequency according to required for emulation module each in cycle synchronisation list,Itself frequency is arranged.Preferably, the frequency of time server itself can set for frequency required for all emulation modulesThe least common multiple set.For example, if there are three emulation (module 4, module 5 and module 6) modules, and the time cycle is added altogether, andSet of frequency required for module 4 is 6Hz, and set of frequency required for module 5 is 3Hz, and set of frequency required for module 6 is4Hz, then the set of frequency of itself can be 12Hz (12 is 6,3,4 least common multiple) by time server.Time serverThe frequency of itself can be used for the virtual time of renewal time server.Illustratively, if the frequency of time server itself is12Hz, then without other factors influence in the case where, time server by with the frequency renewal time server of 12Hz it is virtual whenBetween, and 1/12 (s) is more newly increased every time.
Control instruction can be with characterization control simulation process acceleration or deceleration.If also, control instruction characterization control emulatedJourney accelerates, then the corresponding second frequency of any emulation module is greater than the corresponding first frequency of the emulation module；If control instruction tableSign control simulation process slows down, then the corresponding second frequency of any emulation module is less than the corresponding first frequency of the emulation module.Illustratively, if there are three emulation module (module 1, module 2 and module 3) modules, and time cycle, and module 1 corresponding the is added altogetherOne frequency is 6Hz, and the corresponding first frequency of module 2 is 3Hz, and the corresponding first frequency of module 3 is 1Hz, if then control instruction tableSign control simulation process accelerates, then the corresponding second frequency of module 1 can be 12Hz, and the corresponding second frequency of module 2 can be6Hz, the corresponding second frequency of module 3 can be 2Hz.
In step 12, it according to each second frequency, is sent to emulation module corresponding with second frequency and carries having timeThe triggering command of stamp.
Wherein, timestamp can serve to indicate that when the triggering command for carrying the timestamp is sent locating for time serverThe virtual moment.Time server sends to emulation module corresponding with second frequency according to each second frequency and carries having timeThe triggering command of stamp completes the artificial tasks for corresponding to corresponding timestamp to trigger each emulation module.Shown in aboveFor three emulation modules (module 1, module 2 and module 3), the corresponding first frequency of module 1 is 6Hz, module 2 corresponding firstFrequency is 3Hz, and the corresponding first frequency of module 3 is 1Hz, and control instruction characterization control simulation process accelerates, so that module 1Corresponding second frequency is 12Hz, and the corresponding second frequency of module 2 is 6Hz, and the corresponding second frequency of module 3 is 2Hz.So,For module 1, time server is 12 triggering commands of transmission per second by 6 triggering commands (before variation) variations of transmission per second(after variation), wherein time server is into 12 triggering commands that module is sent after variation, preceding 6 triggering commands and variation6 times transmitted by preceding are identical (that is, entrained timestamp do not change), to apply the second frequency since n-th secondFor rate, before variation, time server should send 6 triggering commands corresponding to n-th second, and after variation, Time ServiceIn 12 triggering commands transmitted by device, the triggering command and preceding should send for n-th second the 6 time triggering command of variation of preceding 6 transmissionsIdentical, then the triggering command of 6 transmissions is then identical as preceding should send for (n+1)th second 6 time triggering command is changed, and therefore, is becomingIt is that the artificial tasks of 2s (real time) should be spent to complete in 1s (real time) script in fact, to realize after changeControl simulation process required by control instruction accelerates.Similarly for module 2 and module 3, not repeated description herein.AccordinglyGround, if control instruction characterization control simulation process slows down, time server will reduce to each emulation module and send messageIt is imitative to reach control to make the artificial tasks that should spend m1 (duration) originally that m2 (duration, and m1 < m2) be spent just to complete for frequencyThe effect that true process is slowed down.
Through the above scheme, in response to receiving the control instruction of characterization control simulation process acceleration or deceleration, according to imitativeThe first frequency for sending message during true to each emulation module, determines to each emulation module send the second of message respectivelyFrequency, and according to each second frequency, the triggering command for carrying timestamp is sent to emulation module corresponding with second frequency,The artificial tasks for corresponding to corresponding timestamp are completed to trigger each emulation module.In this manner it is achieved that adding to simulation processSpeed is slowed down, freely control simulation process the time it takes, also, by the acceleration to simulation process, can be in short-termIt is interior to find the problem and solve, by the deceleration to simulation process, more careful grind can be carried out to the part to go wrongStudy carefully, such as is investigated for accident.To be conducive to the research and development of research staff, higher-quality emulation may be implemented.
In order to make those skilled in the art more understand technical solution provided in an embodiment of the present invention, below to aboveCorresponding steps are described in detail.
Firstly, in response to receiving control instruction, being sent out according in simulation process to each emulation module in step 11The first frequency of message is sent, the second frequency for sending message to each emulation module is determined respectively, is described in detail.
In a kind of possible embodiment, control instruction may include the speed regulating degree characterized to simulation processAdjust information.Therefore, in this embodiment, step 11 may comprise steps of:
According to information and first frequency is adjusted, the second frequency that message is sent to each emulation module is determined respectively.
Control instruction may include adjusting information, and adjusting information, which can be used for characterizing, adjusts journey to the speed of simulation processDegree.For same emulation module, if adjusting information representation is big to the speed regulating degree of simulation process, the emulation module firstGap between frequency and second frequency can be larger, and if adjusting information representation to the speed regulating degree of simulation processSmall, then the gap between the emulation module first frequency and second frequency can be smaller.
In a kind of possible embodiment, different regulating gradients can be set for the acceleration/deceleration of simulation process, oftenA kind of regulating gradient can correspond to different frequency variations.For example, it is arranged two if the acceleration/deceleration of simulation processRegulating gradient B1 and B2 (the corresponding regulating degree of B2 be greater than the corresponding regulating degree of B1), be corresponding in turn in frequency change C1 andC2 (C2 is greater than C1).So, if control instruction characterization is corresponding to the adjusting information that simulation process accelerates and includes in control instructionIn regulating gradient B2, if then the first frequency of a certain emulation module is D1, the corresponding second frequency of the emulation module is then D1+C2.If control instruction characterization corresponds to regulating gradient B1 to the adjusting information that simulation process slows down and includes in control instruction,If the first frequency of a certain emulation module is D2, the corresponding second frequency of the emulation module is D2-C1.It should be noted thatThe regulating gradient and the corresponding frequency change of each regulating gradient that accelerate, slow down may be the same or different, withAnd for different emulation modules, acceleration, the regulating gradient slowed down and the corresponding frequency change of each regulating gradient can phasesTogether, it can also be different, the disclosure is not limited this.
In alternatively possible embodiment, adjust information can for for before same simulation process, adjusting with adjustingThe ratio of occupied practical duration afterwards.Illustratively, adjusting information can be used to indicate that the specific setting to regulating degree.To adjustIt saves before being adjusted in information and the ratio of occupied practical duration is 2 citings after adjusting, exactly adjusting the preceding duration spent is2 times of duration used after adjusting, that is, by 2 speed of simulation process (acceleration)；With adjust in information adjust before with adjust after instituteThe ratio of the practical duration occupied is 1/2 citing, and the duration that is spent is the half of duration used after adjusting before exactly adjusting,It is exactly by 0.5 speed of simulation process (deceleration).
Correspondingly, it according to information and first frequency is adjusted, determines to each emulation module send the second of message respectivelyFrequency may comprise steps of:
Obtain first frequency corresponding with first object emulation module；
Calculate second frequency corresponding with first object emulation module.
Wherein, first object emulation module can be any emulation module.It should be noted that practical execute in this methodStep when, each emulation module can become a first object emulation module, that is, time server will be eachEmulation module adjusts a secondary frequencies.Operation is adjusted to the frequency of each emulation module and follows the step and to the stepIt illustrates.
Illustratively, it can calculate with first object emulation module according to following formula to corresponding second frequency f2:
f2=f1*k
Wherein, f1For first frequency corresponding with first object emulation module, k be for same simulation process, adjusting beforeWith the ratio of practical duration occupied after adjusting.
For example, if k=2, that is, the duration that is spent is 2 times of duration used after adjusting before adjusting, that is, will be imitatedTrue 2 speed of process (acceleration), and the first frequency f of first object emulation module1=3Hz, then the first object emulation module pairThe second frequency f answered2=6Hz.
Using aforesaid way, can the regulating degree to simulation process acceleration or deceleration controlled with high accuracy, makeThe controllability of simulation process is stronger, easily studied.
In the following, to, according to each second frequency, being carried to emulation module corresponding with second frequency transmission in step 12The triggering command of timestamp is described in detail.
In a kind of possible embodiment, step 12 be may comprise steps of:
According to each second frequency, the triggering for carrying timestamp to emulation module corresponding with second frequency transmission refers toIt enables.
After determining the second frequency for each emulation module, time server can be according to each emulation module pairThe second frequency answered sends triggering command to corresponding emulation module.Illustratively, if there are two emulation module (module 7 and moulds altogetherBlock 8), wherein the second frequency of module 7 is 4Hz, and the second frequency of module 8 is 6Hz, then time server can according to 4Hz toModule 7 sends triggering command, sends triggering command to module 8 according to 6Hz.
In alternatively possible embodiment, it is contemplated that each emulation module is likely to occur delay when executing task, walksRapid 12 may comprise steps of:
In the first step, it is sent to the second target simulator module and carries the timestamp for being used to indicate the destination virtual momentTriggering command；
In the second step, imitative for being used to indicate for destination virtual moment transmission if receiving the second target simulator moduleThe task that true task is completed completes message and has received the task completion message of other emulation modules, it is determined that updatedThe destination virtual moment, and using the updated destination virtual moment as the new destination virtual moment, and return to above-mentioned first step.
Wherein, the second target simulator module can be any emulation module.It should be noted that practical execute in this methodStep when, each emulation module can become the second target simulator module, that is, time server will be continuously it is eachEmulation module sends triggering command, but time server is mutually isolated the operation of each the second target simulator module, that is to say, that for time server with during once executing above-mentioned two step, the second target simulator module is constant, do not appear in same the case where the second target simulator module changes in the process.Time server emulates mould to eachThe operation of block follows above-mentioned steps and the explanation to above-mentioned steps.
The triggering command for carrying the timestamp for being used to indicate the destination virtual moment is being sent to the second target simulator module.Second target simulator module after receiving the triggering command with timestamp, appoint by achievable emulation corresponding with the timestampBusiness, and sent after completion task to time server and be used to indicate the task completion message that this artificial tasks is completed.
Time server is receiving the second target simulator module for the task completion message of destination virtual moment transmissionAfterwards, if the task that time server has received other emulation modules at this time completes message, it is determined that updated destination virtualMoment.Wherein, other emulation modules include in addition to the second target simulator module, the destination virtual moment in the updated are needed to arrive itThe preceding emulation module for completing artificial tasks, the updated destination virtual moment was increased on the basis of the virtual moment not updatedTarget duration obtains, and the numerical value of target duration is equal to the inverse of second frequency corresponding with the second target simulator module.
Time server receive the second target simulator module for the destination virtual moment send task complete message andHave received other emulation modules task complete message, it may be said that it is bright institute it is in need in the updated the destination virtual moment arrivalCompleting before for task is completed, therefore can promote virtual time, continues the virtual time of time server, and moreIt is newly the updated destination virtual moment.For the second target simulator module, updated destination virtual moment and updateThe time differed between the preceding destination virtual moment should be the second target simulator module corresponding period, that is, the second targetThe inverse of the corresponding second frequency of emulation module.And if not receiving the second target simulator module and being sent for the destination virtual momentTask complete message, then illustrate that the second target simulator module postpones, therefore will not determine updated destination virtualMoment, and can wait until that receive the second target simulator module disappears for the task completion that the destination virtual moment sends alwaysBreath and the task completion message for having received other emulation modules, just can determine whether the updated destination virtual moment.NamelyIt says, if detecting the presence of emulation module is not timely completed artificial tasks (do not receive corresponding task and complete message), at thisIn the open method provided, time server will be waited always, until all emulation modules that should complete task returnTask completes message, also, in waiting process, the time of time server be will not continue to, that is to say, that if the timeThe server virtual moment waits when being P, then before waiting for, no matter how much the actual time passs, in time serverIn, it will be always held at the P moment, until all emulation modules that should complete task return task and complete message.In detailExplanation will be provided below in conjunction with actual example.
After determining the updated destination virtual moment, so that it may empty using the updated destination virtual moment as new targetThe quasi- moment, and first step is returned, to constantly trigger the artificial tasks of each emulation module according to second frequency.
Fig. 2 and Fig. 3 is in the method for the speed of the adjusting simulation process provided according to the disclosure, according to each second frequencyRate sends the triggering command for carrying timestamp to emulation module corresponding with second frequency, complete to trigger each emulation moduleAt a kind of illustrative schematic diagram of a scenario for the artificial tasks for corresponding to response time stamp.As shown in Figures 2 and 3, when showingBetween server and three emulation modules (emulation module 31, emulation module 32 and emulation module 33), wherein the of emulation module 31Two frequencies are 6Hz, and the second frequency of emulation module 32 is 3Hz, and the second frequency of emulation module 33 is 1Hz, also, in the figureThe task used time is completed with the rectangle representation module 31 with oblique line, completes the task used time with the rectangle representation module 32 of white filling,The task used time is completed with the rectangle representation module 33 of filled black.In the case where without task delay, three in 1sThe task of module normally completes and (does not have module to postpone) schematic diagram of a scenario of situation, is used as reference, wherein in order to say hereinafter1s is divided into six parts with 0~6 this several dotted lines, marks in figure, 7 moment are represented, when two neighboring by bright convenienceBetween difference be 1/6 (s), hereinafter will be directly illustrated with 0~6 pair of each moment, no longer illustrate the actual time difference 1/6(s).Occur postponing (module 32, module between 1~moment of moment 2 to module 31 below in conjunction with Fig. 3 and above step33 normally complete task in the 1s) the case where be explained.
Firstly, being that the second target simulator module is illustrated with module 31.At 0 moment, needs to send to module 31 and triggerInstruction, therefore first step is first carried out, triggering command is sent to module 31.Then, the task completion for receiving module 31 disappearsBreath, at this point, the updated destination virtual moment was 1 moment, and the moment arrives and needs to complete the emulation mould of artificial tasks beforeBlock only has module 31, therefore, can be empty as the new target of time server by the updated destination virtual moment (1 moment)Quasi- moment (correspondingly, the virtual moment of time server was 1 moment at this time), and return to first step, that is, 1 moment toModule 31 sends triggering command.Then, the receiving module 31 of the task completes message (as shown in figure 3, receiving appointing for module 31Business is completed message and is spent a large amount of time), at this point, the updated destination virtual moment was 2 moment, and needed before moment arrivalCompleting the emulation modules of artificial tasks, there are also modules 32 in addition to module 31, therefore, if the having received module 32 of the task is completedMessage, then can be (corresponding as the new destination virtual moment of time server by the updated destination virtual moment (2 moment)Ground, the virtual moment of time server was 2 moment at this time), and first step is returned to, that is, send to module 31 at 2 momentTriggering command.Subsequent step is similar to what is be outlined above, is not repeated to describe.Above description is from Postponement module (module31) explanation that the angle of itself carries out.
Explanation will be re-started from the angle of normal module below, will be that the second target simulator module is said with module 32It is bright.It at 0 moment, needs to send triggering command to module 32, therefore first step is first carried out, sends triggering to module 32 and refer toIt enables.Then, the receiving module 32 of the task completes message, at this point, the updated destination virtual moment was 2 moment, and the momentArriving, there are also modules 31 in addition to module 32 for the emulation module for needing to complete artificial tasks before, since module 31 postpones, InThe task that the receiving module 32 of the task completes not receiving module 32 when message completes message, therefore, time serverThe virtual moment will remain in for 1 moment, and the task of module 31 is waited to complete message, disappear until receiving the task from module 31Breath, time server just can by the updated destination virtual moment (2 moment) as new destination virtual moment (correspondingly, thisWhen time server the virtual moment be 2 moment), and return to first step, that is, send triggering to module 32 at 2 moment and refer toIt enables.For subsequent process to it is the above similar, do not repeat to repeat herein.
That is, time server and normally complete the emulation module of task will be to the emulation module postponedIt is waited, postpones current time, until the emulation module postponed completes task, to realize time synchronization.
Using aforesaid way, the Time Synchronization Mechanism provided by time server and the disclosure be may be implemented eachThe time synchronization of emulation module, and the mutual waiting between emulation module may be implemented, and can be used as adding for simulation processSpeed or slow down basis, prevent to during simulation process acceleration or deceleration time of occurrence dislocation, data perturbation situations such as, guaranteeSimulated mass.
In addition, on the basis of above-mentioned steps, in the method that the disclosure provides, step 12 can with the following steps are included:
Refer to the triggering for carrying the timestamp for being used to indicate the destination virtual moment with the transmission of the second target simulator moduleStart timing when enabling；
If timing duration is greater than or equal to preset duration and does not receive the task completion of the second target simulator module transmissionMessage exports prompt information.
The case where task postpones is completed for emulation module, completion disappears if emulation module can not return to task for a long timeBreath or emulation module failure, which make it forever, can not return to task completion message, in order to avoid time server and other emulationThe unlimited waiting of module, can introduce timeout treatment mechanism.That is, carrying to the transmission of the second target simulator module for referring toStarting timing when showing the triggering command of the timestamp at destination virtual moment, wherein timing criteria should be reference with the real time,Exactly send the real time passed through after triggering command.If timing duration is greater than or equal to preset duration and does not receive yetThe task that second target simulator module is sent completes message, then prompt information can be exported, to prompt the second target simulator moduleIt is abnormal, it is handled convenient for staff.Illustratively, time server can export prompt letter to the terminal where staffBreath.
In addition, if timing duration is greater than or equal to preset duration and does not receive the transmission of the second target simulator module yetTask completes message, illustrates emulation module exception, can stop current simulation process at this time, waits related personnel's processing.
Using aforesaid way, start timing when to triggering command is sent with the second target simulator module, if timing durationReach the task completion message that preset duration does not receive the transmission of the second target simulator module yet, then can export prompt information,Related personnel's processing is waited, the unlimited waiting of time server and emulation module without exception is prevented.
