To ensure time synchronization of the various operator subunits, a time alignment signal is typically sent out at equal intervals from a synchronization source, and then received by each of the simulated eukaryotes for further time alignment. Theoretically, the signals emitted by the communication sources are precisely equally spaced, however, the time instants received by the simulated cells are not necessarily equally spaced, possibly due to transmission loss, etc. Therefore, to ensure the time synchronization precision of the large-scale real-time simulation parallel computation, it is very important to calibrate the communication interval.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The following describes a method for calibrating a communication interval in power real-time simulation provided by the embodiment of the present application. Referring to fig. 1, a method for calibrating a communication interval in power real-time simulation according to an embodiment of the present application may include the following steps:
step S101, a communication interval sequence which is closest to the current moment and has a preset length is obtained.
Referring to FIG. 2, to ensure time synchronization of each operation subunit, a synchronization source typically sends out a synchronization signal at regular intervals, which may be a rising edge signal, for time alignment, and each emulation core sends back a reply signal to the synchronization source immediately after receiving the signal. Theoretically, the intervals of signals sent by the communication sources are exactly equal, however, the time of receiving by the simulated nucleus is not necessarily equal, possibly due to transmission loss and the like.
For example, referring to fig. 3, the time instants at which the synchronization sources send out the rising edge signals at equal intervals are t1, t2, t3, etc. respectively, and taking the simulation core 1 as an example, the time instants at which the simulation core receives the rising edge signals sent out by the synchronization sources are t11, t12, t13, etc. respectively, then it can be obtained that the time intervals between the simulation core receiving the synchronization signals of the synchronization sources are Δ ta respectively 11 、Δta 12 、Δta 13 Etc., the sequence of communication intervals may be represented as:
A＝{Δta 1i ，i＝1，2，...，N}
generally, the network is designed to be exclusive, and each simulated eukaryotic cell and the synchronous source share an exclusive communication channel, so the communication interval is stable, that is, each simulated eukaryotic cell and the synchronous source share an exclusive communication channelCommunication interval delta ta 11 、Δta 12 、Δta 13 Etc. with very little phase difference between them.
Although the network is exclusive and will not be interfered by other simulated eukaryons, if the communication medium is interfered, communication failure may occur, and then retransmission may occur, resulting in Δ ta 11 、Δta 12 、Δta 13 The equality is not completely consistent, and theoretically, most of the Δ ta 11 、Δta 12 、Δta 13 The time is constant and occasionally has a value of about 1.5 times (1 time for bi-directional co-transmission), about 2 times (2 times for bi-directional co-transmission), about 2.5 times (3 times for bi-directional co-transmission), etc., and steps S102 to S104 consider that the peak jitter is identified and filtered in the waveform containing the peak generated by retransmission, and finally obtain an accurate interval close to the real one.
Considering the situation that the communication channel is the closest, it is necessary to intercept the communication intervals of the latest period of time, for example, the communication intervals within the latest 1 second, and sort the communication intervals according to the occurrence time to obtain the communication interval sequence.
Step S102, constructing a second interval sequence based on the communication interval sequence.
Wherein the second interval sequence comprises a plurality of local minima in the communication interval sequence. For example, the communication interval sequence may be divided into a plurality of subsequences, which may have partial overlap, then minimum values are extracted from each subsequence, and finally the second interval sequence is formed by the minimum values.
Step S103, a critical value is determined based on the second interval sequence, and elements smaller than the critical value are screened from the second interval sequence to obtain a third interval sequence.
When network interference exists, communication errors occur and data packet retransmission occurs, so that a communication interval becomes large, that is, an abnormal communication interval occurs. Since the second interval sequence includes a plurality of local minima in the communication interval sequence, an appropriate threshold value can be calculated based on the local minima, and the abnormal communication interval can be eliminated by using the threshold value.
And step S104, obtaining the average value of the third interval sequence to obtain a target communication interval.
The method includes the steps that a communication interval sequence which is closest to the current moment and has a preset length is obtained. The communication interval in the communication interval sequence is the interval between the received synchronous signals of the synchronous source, and reflects the nearest working condition of a communication channel between the simulation core and the synchronous source. Then, a second interval sequence is constructed based on the communication interval sequence. Wherein the second interval sequence comprises a plurality of local minima in the communication interval sequence. Because the communication interval is only increased but not decreased when there is communication disturbance, a critical value may be determined based on each communication interval in the second interval sequence, where the critical value may be used to eliminate communication interval anomalies, that is, elements smaller than the critical value are screened from the second interval sequence, so as to obtain a third interval sequence. And finally, obtaining the average value of the third interval sequence to obtain a target communication interval. The communication time delay and the jitter caused by the data packet retransmission generated by the communication disturbance are considered, the interference of the communication time delay and the jitter is eliminated to a certain extent, and the communication interval which is closer to the real condition can be obtained.
In some embodiments of the present application, the process of obtaining the communication interval sequence with the preset length closest to the current time in the step S101 may include:
s1, acquiring each time of receiving a synchronization signal sent by a synchronization source.
Each time occurs within K seconds from the current time, and K is a preset value, for example, 1, 1.5, 2, and so on, depending on how long the communication condition of the historical period needs to be considered.
And S2, calculating a plurality of communication intervals based on each time.
Since the transmission and return of the synchronization signal can occur a plurality of times within K seconds, a plurality of time values can be obtained, and after the time values are chronologically ordered, the time interval between adjacent times is calculated, and a plurality of communication intervals can be obtained.
And S3, constructing a communication interval sequence based on the plurality of communication intervals.
Specifically, the communication intervals are time-ordered according to the time generated by each communication interval, and a time-ordered communication interval sequence a = { Δ ta can be obtained 1i I =1,2,.., N } is shown in fig. 4.
In some embodiments of the present application, the value of K is 1, i.e. consider the case of a communication interval within the last 1 second.
In some embodiments of the present application, the step S102 of constructing the second interval sequence based on the communication interval sequence may include:
s1, with a first element of the communication interval sequence as a starting point, sliding in the communication interval sequence by a sliding window with a preset size and a preset step length to obtain a plurality of communication interval subsequences.
For example, referring to fig. 5, assuming that the communication interval sequence includes N elements, the size of the sliding window is M, and the preset step size is 1, then by sliding the sliding window in the communication interval sequence, N- (M-1) communication interval subsequences can be obtained.
And S2, taking the minimum value of each communication interval subsequence to obtain a plurality of local minimum values.
Specifically, elements (communication intervals) in a communication interval subsequence are compared to obtain the minimum communication interval of the communication interval subsequence, and N- (M-1) communication interval subsequences can obtain N- (M-1) local minimum values in total.
S3, constructing a second interval sequence A by using the local minimum values min 。
According to the test statistical data, the probability of x retransmissions (generally x =3, if the network interference is serious, the number of consecutive retransmissions is large, a larger number can be taken, and it is only required to be 1 larger than the maximum number of consecutive retransmissions) occurring continuously is approximately 0.
In some embodiments of the application, 5. The method according to claim 4, wherein the predetermined size is 3.
In some embodiments of the present application, the step S103 of determining the threshold value based on the second interval sequence may include:
s1, obtaining the mean value of each element in the second interval sequence.
Namely to A min Taking the average value of each element in the solution to obtain
S2, multiplying the average value by a preset coefficient to obtain a critical value:
in some embodiments of the present application, the preset coefficient k may be 1.25.
