Specific embodiment
Because of various fields, as the real time data of industrial control field be generated by collector timing sampling, so
Between the corresponding timestamp of real time data often it is regular be incremented by, as theoretically meet between the corresponding timestamp of real time data as
Lower feature:
T1, t2=t1+ △ t, t3=t2+ △ t ... ..tn=tn-1+ △ t, wherein △ t is the sampling interval, thus can be total
Bear the theory rule followed between two neighboring timestamp in the timestamp sequence being made of multiple timestamps are as follows: tn=tn-1
+ △ t (n=2,3 ...).
But actually due to the acquisition precision of collector and other a variety of causes, each timestamp will appear to a certain degree
Deviation, the value of the timestamp in timestamp sequence are as follows: t1+d1, t2=t1+ △ t+d2, t3=t2+ △ t+d3 ...,
Tn=tn-1+ △ t+dn (n >=2), therefore followed on theoretical regular basis between two neighboring timestamp in timestamp sequence
Rule are as follows:
Tn=tn-1+ △ t+dn (n >=2).Wherein d2, d3 ..., dn is deviation, if collector is uninterruptedly adopted
Collection, then the value of △ t+dn can fluctuate above or below sampling interval △ t.
Assuming that each timestamp is indicated using int64 when storage time stabs sequence, then each timestamp occupies 8
Byte, this memory space for resulting in timestamp sequence to occupy can be very big, and inventor can use for reference above-mentioned tn=tn- by observation
The rule of 1+ △ t+dn (n >=2) replaces timestamp using deviation, why using deviation replace timestamp be because are as follows:
For deviation for timestamp, the value of deviation will be much smaller than the value of timestamp, in this way can when storing deviation
It to use lesser memory space, such as uses but is not limited to store using 2 bytes, so that the storage that timestamp sequence occupies
Space is greatly reduced, and is based on this thinking, and the present invention provides a kind of date storage method, data restoration method and device.
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to Fig. 1, it illustrates a kind of flow chart of date storage method provided in an embodiment of the present invention, for reducing
The memory space that timestamp sequence occupies, may comprise steps of:
S101: obtaining i-th of timestamp in original time stamp sequence, and i is from 2 any one number into n, and n is original
Timestamp sum in beginning timestamp sequence.It is to be understood that in original time stamp sequence each timestamp be ordered as from 1 to
N, but during actual storage each timestamp can be successively obtained since the 2nd timestamp of original time stamp sequence
Until arrive original time stamp sequence the last one timestamp, while the 2nd timestamp between the last one timestamp appoint
One timestamp only obtains once, is performed both by subsequent step to each timestamp.Why can be obtained since the 2nd timestamp
Take is because being and the 1st timestamp based on the relationship between i-th of timestamp and (i-1)-th timestamp in follow-up storage
It is first in original time stamp sequence, the timestamp before the 1st timestamp is not present for the 1st timestamp,
And it also can determine the storage mode of the 1st timestamp by the relationship of the 1st timestamp and the 2nd timestamp.
It if included 10 timestamps in original time stamp sequence, is then successively obtained since the 2nd timestamp, until obtaining
When to the 10th timestamp, acquisition terminates, one timestamp of every acquisition, executes following steps to the timestamp currently got,
To judge the timestamp currently got and the relationship between its adjacent previous timestamp, and determined such as based on the relationship
What storage time stamp.
S102: if the relationship between i-th of timestamp and (i-1)-th timestamp is serial relation, and i-th of timestamp is not
It is n-th of timestamp, then adds 1 return to execute the step of obtaining i-th of timestamp in original time stamp sequence i.
In the present embodiment, judge a kind of feasible pattern of the relationship between i-th of timestamp and (i-1)-th timestamp
It is: obtains i-th of timestamp and (i-1)-th timestamp, i-th of timestamp and (i-1)-th timestamp is based on, when obtaining i-th
Between stab and (i-1)-th timestamp between deviation (being denoted as i-th of deviation in order to facilitate description), if i-th of deviation
With continuity, it is determined that the relationship between i-th of timestamp and (i-1)-th timestamp is serial relation, if i-th of deviation
Value does not have continuity, then the relationship between i-th of timestamp and (i-1)-th timestamp is discontinuous relationship.
Wherein judge whether i-th of deviation there is a kind of successional feasible pattern to be: whether judging i-th of deviation
In threshold range, if i-th of deviation, in threshold range, i-th of deviation has continuity, if i-th inclined
Difference is not in threshold range, then i-th deviation does not have a continuity, threshold range can be but not limited to [- 32768 ,+
32767], if therefore i-th of deviation be located in [- 32768 ,+32767], then confirm that i-th of deviation has continuity, it is no
Do not have continuity then.
A kind of feasible pattern for determining i-th of timestamp not and be n-th of timestamp is: obtaining the value of i, acquisition time stamp
Total n, judges whether i is greater than or equal to n, if i is greater than or equal to n, i-th of timestamp is n-th of timestamp, if i
Less than n, then i-th of timestamp is not n-th of timestamp.
It should be understood that adding 1 return to execute the step of obtaining i-th of timestamp in original time stamp sequence i is
Refer to: the relationship between i-th of timestamp and (i-1)-th timestamp is serial relation, then returns and obtain original time stamp sequence
In i+1 timestamp, relationship such as between the 5th timestamp and the 4th timestamp is serial relation, then continues to obtain
The 6th timestamp in original time stamp sequence.
S103: if the relationship between i-th of timestamp and (i-1)-th timestamp is serial relation, and i-th of timestamp is
N-th of timestamp then stores the 1st timestamp, the 2nd timestamp of storage to n-th of timestamp in original time stamp sequence
Respective deviation and storage deviation number.
In the present embodiment, it stores the 1st timestamp in original time stamp sequence, store the 2nd timestamp to n-th
A kind of feasible pattern of the respective deviation of timestamp and storage deviation number is: according to the 1st timestamp to n-th of time
The sequence in original time stamp sequence is stabbed, the 2nd the 1st timestamp of storage, storage timestamp are respective to n-th of timestamp
Deviation and storage deviation number are into continuous time stamp sequence.
That is, also saying relative to original time stamp sequence, each storage unit is stored in original time stamp sequence
One timestamp, and the 1st storage unit storage in continuous time stamp sequence is the 1st timestamp, other storage units
Storage be timestamp deviation, and in continuous time stamp sequence the content of each storage unit storage be still according to it is original when
Between stab sequence in the 1st timestamp to n-th of timestamp sequence.
The wherein deviation of the 2nd timestamp x-th of timestamp into n-th of timestamp are as follows: x-th of timestamp and xth-
The deviation between deviation or x-th of timestamp and the 1st timestamp between 1 timestamp, x be from 2 into n
Any one number.That is, each timestamp of the 2nd timestamp into n-th of timestamp has 1 corresponding deviation
Value such as obtains the 2nd timestamp and the respective deviation of n-th of timestamp by above-mentioned tn=tn-1+ △ t+dn (n >=2)
D2, d3 ..., dn, and it is based on d2, d3 ..., the sequence of dn is sequentially stored in continuous time stamp sequence, by tn=
Tn-1+ △ t+dn (n >=2) know that deviation is the deviation between -1 timestamp of x-th of timestamp and xth, may be used also certainly
To use other modes, such as deviation between x-th of timestamp and the 1st timestamp, i.e., on the basis of the 1st timestamp,
Deviation of the other times stamp relative to the 1st timestamp is calculated, or using being calculated on the basis of other times stamp, originally
Embodiment is not illustrating.
It should be understood that when storing the 1st timestamp in original time stamp sequence, the 2nd timestamp to n-th
Between while stab respective deviation, it is also desirable to store deviation number, deviation number can be passed through in data convert in this way
Determine the deviation stored in continuous time stamp sequence, if the timestamp t2 to t5 in original time stamp sequence is serial relation,
Then in continuous time stamp sequence while storage t2 respective to t5 deviation, also storage deviation number to consecutive hours
Between stab sequence in, this continuous time stab sequence in deviation number value be 4.
In order to whether be the data stabbed continuous time in sequence convenient for the current data of determination during data convert,
Continuous time stamp sequence can be marked by way of identifier, if the 1st in continuous time stamp sequence is mark
The value of symbol, the value of the identifier are used to show that the relationship between the timestamp of continuous time stamp sequence storage to be continuous
Relationship, for example, when identifier value be 1, be shown to be continuous time stamp sequence and continuous time stamp sequence storage timestamp it
Between relationship be serial relation, then the number stored for the 2nd storage unit into n-th of storage unit in data convert
Timestamp is restored according to the mode that tn=tn-1+ △ t+dn (n >=2) can be used, dn is then the n-th of n-th of storage unit storage
The corresponding deviation of a timestamp, △ t are the sampling interval.The byte for wherein storing the storage unit of deviation can be according to deviation
Depending on, if deviation needs to occupy 2 bytes or 4 bytes, then 2 bytes can be distributed for storage unit or 4 bytes are come
Deviation is stored, the byte of storage unit distribution is not defined herein, as long as being less than timestamp in original time stamp sequence
The byte of occupancy.
And it can be stabbed thus in continuous time from tn=tn-1+ △ t+dn (n >=2) it is found that needing △ t in reduction
The sampling interval is stored in sequence, which can store the last one storage unit in continuous time stamp sequence, i.e. phase
For original time stamp sequence, increase a storage unit to store the sampling interval, as shown in table 1.
A kind of storage mode of 1 continuous time of table stamp sequence
Certainly other storage modes, the deviation corresponding with the 2nd timestamp such as after the 1st timestamp can also be used
The sampling interval is stored between value, this present embodiment is not being illustrated, or the sampling interval is interacted using preparatory interactive mode,
In order to carry out data convert.For deviation number, it can store after the 1st timestamp and the 2nd time
It stabs between corresponding deviation, or is stored in other positions, the present embodiment is to the position of deviation number without limiting.
From above-mentioned technical proposal it is found that by obtaining i-th of timestamp in original time stamp sequence, if i-th of time
Relationship between stamp and (i-1)-th timestamp is serial relation and i-th of timestamp is not that n-th of timestamp then adds 1 return to i
I-th of the timestamp obtained in original time stamp sequence is executed, if the relationship between i-th of timestamp and (i-1)-th timestamp
For serial relation and i-th of timestamp is that n-th of timestamp then stores the 1st timestamp in original time stamp sequence, storage
2nd timestamp can be restored each to the respective deviation of n-th of timestamp and storage deviation number by deviation
The corresponding unique time stamps of deviation, being achieved in by way of storing deviation reduces the occupancy of memory space, in this way
It does not need to abandon deviation when storing deviation, and makes original time stamp sequence by way of storing deviation
Each timestamp in column can accurate reproduction, to improve the integrality and authenticity of timestamp.
Opposite, if the case where relationship between i-th of timestamp and (i-1)-th timestamp is discontinuous relationship, i-th
Timestamp is also required to be stored, and present embodiments provides the flow chart of another date storage method thus, when illustrating i-th
Between stab and (i-1)-th timestamp between relationship be discontinuous relationship when storage mode, base of the date storage method in Fig. 1
It may comprise steps of on plinth:
S104: if relationship between i-th of timestamp and (i-1)-th timestamp is discontinuous relationship, and i-th of timestamp
It is n-th of timestamp, then individually stores i-th of timestamp.
Wherein judge the relationship between i-th of timestamp and (i-1)-th timestamp and determines that i-th of timestamp is not n-th
A timestamp is identical as above-mentioned steps S102 implementation procedure and principle, is not repeating herein.But with step S102 difference
It is: if the relationship between two adjacent timestamps is discontinuous relationship and i-th of timestamp is n-th of timestamp, can incites somebody to action
I-th of timestamp individually stores, and such as i-th of timestamp is stored in an independent time stamp sequence, which stabs sequence
Column can only store one and the relationship of adjacent timestamp is the timestamp of discontinuous relationship, or store multiple and adjacent
The relationship of timestamp is the timestamp of discontinuous relationship.
It is corresponding with continuous time stamp sequence, independent time stamp sequence is also required to configure taking for an identifier for it
Value, such as value in the 1st record identifier of independent time stamp sequence, the value of the identifier and continuous time are stabbed in sequence
The value of identifier is different, if the value of identifier in independent time stamp sequence is 0, to show in independent time stamp sequence
It is discontinuous relationship that each timestamp of storage, which is with the relationship of other times stamp,.
Herein it should be understood that if an original time stamp sequence, obtain at least one continuous time stamp sequence and
At least one independent time stabs sequence, and each independent time stamp sequence only stores a timestamp, then in storage consecutive hours
Between stab sequence and independent time stamp sequence when, need according to continuous time stab sequence and independent time stamp sequence in timestamp in original
Sequence in beginning timestamp sequence stores, if original time stamp sequence is by 10 timestamps, wherein the 1st timestamp is to the 3rd
A timestamp forms a continuous time stamp sequence (being denoted as continuous time stamp sequence 1 for ease of description), and the 4th timestamp exists
(it is denoted as independent time stamp sequence 1 for ease of description) in one independent time stamp sequence, the 5th timestamp sequence is to the 10th
Timestamp form continuous time stamp sequence (be denoted as continuous time stamp sequence 2 for ease of description, then in storage this three
The positional relationship of a timestamp sequence are as follows: continuous time stabs sequence 1, independent time stamp sequence 1 and continuous time and stabs sequence 2, this
Sample can successively restore the data in these three timestamp sequences in reduction, the sequence of the timestamp after reduction are as follows:
1st timestamp, the 2nd timestamp ..., the 10th timestamp, sequence and the timestamp in original time stamp sequence
It sorts identical.
If multiple timestamps are stored in an independent time stamp sequence, in order to make the sequence of the timestamp restored
It is identical as the sequence of timestamp in original time stamp sequence, then it needs to stab in sequence and independent time stamp sequence in continuous time and deposit
The sequence of timestamp and deviation in original time stamp sequence is stored up, it in this way can be according to the sequence to reduction in reduction
Timestamp is arranged.
S105: if relationship between i-th of timestamp and (i-1)-th timestamp is discontinuous relationship, and i-th of timestamp
It is not n-th of timestamp, then i-th of timestamp is determined as the 1st new timestamp in original time stamp sequence, and to i
1 return is added to execute the step of obtaining i-th of timestamp in original time stamp sequence.
That is, the relationship between some timestamp in original time stamp sequence and its previous timestamp is not connect
Continuous relationship, then can using timestamp as the 1st new timestamp in original time stamp sequence, then from newly the 1st when
Between stamp start successively to obtain the other times stamp after being located at the 1st new timestamp in original time stamp sequence, and to new
The 1st timestamp and the other times stamp after the 1st new timestamp carry out the judgement of relationship and based on relationship
Storage.
For example, the relationship between the 5th timestamp and the 4th timestamp in original time stamp sequence is discontinuous closes
System, and the 5th timestamp is not n-th of timestamp (i.e. the last one timestamp), then using the 5th timestamp as the new the 1st
A timestamp, and continue successively to obtain the other times stamp after the 1st new timestamp, i.e., the 6th timestamp is to n-th
Timestamp.
S106: to the 1st timestamp in original time stamp sequence to (i-1)-th timestamp based on the pass between timestamp
System's storage.
In the present embodiment, timestamp is based on to the 1st timestamp in original time stamp sequence to (i-1)-th timestamp
Between relationship storage need the value based on i depending on, it is specific: if the value of i is equal to 2, individually to store original time stamp
The 1st timestamp in sequence.
If the value of i is greater than 2, if being serial relation and the time adjacent to each other there are relationship in original time stamp sequence
The continuous time of stamp composition stabs sequence, then stores the 1st timestamp in continuous time stamp sequence, stores the 2nd timestamp extremely
The respective deviation of m-th of timestamp and storage deviation number, m-1 are continuous time to stab sequence large deviations value number.

As shown in figure 4, may include: that the first acquisition module 11, first returns to execution module 12 and the first memory module 13.
First obtains module 11, and for obtaining i-th of timestamp in original time stamp sequence, i is appointing into n from 2
It anticipates a number, n is timestamp sum in original time stamp sequence.It is to be understood that each time in original time stamp sequence
Stamp be ordered as from 1 to n, but during actual storage can since the 2nd timestamp of original time stamp sequence according to
It is secondary to obtain each timestamp until arriving the last one timestamp of original time stamp sequence, at the same the 2nd timestamp to last
Any one timestamp between a timestamp only obtains once, handles each timestamp, why from the 2nd timestamp
Start to please refer to the explanation in embodiment of the method the reason of acquisition.
First returns to execution module 12, if being to connect for the relationship between i-th of timestamp and (i-1)-th timestamp
Continuous relationship, and i-th of timestamp is not n-th of timestamp, then adds 1 to i and trigger the first acquisition module 11 and continue to obtain
Other times stamp in original time stamp sequence.
In the present embodiment, the first return execution module 12 judges the pass between i-th of timestamp and (i-1)-th timestamp
A kind of feasible pattern of system is: i-th of timestamp and (i-1)-th timestamp is obtained, when being based on i-th of timestamp and (i-1)-th
Between stab, obtain the deviation (being denoted as i-th of deviation in order to facilitate description) between i-th of timestamp and (i-1)-th timestamp,
If i-th of deviation has continuity, it is determined that the relationship between i-th of timestamp and (i-1)-th timestamp is continuous closes
System, if i-th of deviation does not have continuity, the relationship between i-th of timestamp and (i-1)-th timestamp is discontinuous
Relationship.Wherein whether i-th of deviation has successional judgement and determines whether i-th of timestamp is n-th of timestamp

From above-mentioned technical proposal it is found that by obtaining i-th of timestamp in original time stamp sequence, if i-th of time
Relationship between stamp and (i-1)-th timestamp is serial relation and i-th of timestamp is not that n-th of timestamp then adds 1 return to i
I-th of the timestamp obtained in original time stamp sequence is executed, if the relationship between i-th of timestamp and (i-1)-th timestamp
For serial relation and i-th of timestamp is that n-th of timestamp then stores the 1st timestamp in original time stamp sequence, storage
2nd timestamp can be restored each to the respective deviation of n-th of timestamp and storage deviation number by deviation
The corresponding unique time stamps of deviation, being achieved in by way of storing deviation reduces the occupancy of memory space, in this way
It does not need to abandon deviation when storing deviation, and makes original time stamp sequence by way of storing deviation
Each timestamp in column can accurate reproduction, to improve the integrality and authenticity of timestamp.

Sample can successively restore the data in these three timestamp sequences in reduction, the sequence of the timestamp after reduction are as follows:
1st timestamp, the 2nd timestamp ..., the 10th timestamp, sequence and the timestamp in original time stamp sequence
It sorts identical.
If multiple timestamps are stored in an independent time stamp sequence, in order to make the sequence of the timestamp restored
It is identical as the sequence of timestamp in original time stamp sequence, then it needs to stab in sequence and independent time stamp sequence in continuous time and deposit
The sequence of timestamp and deviation in original time stamp sequence is stored up, it in this way can be according to the sequence to reduction in reduction
Timestamp is arranged.
Second returns to execution module 15, if being not for the relationship between i-th of timestamp and (i-1)-th timestamp
Serial relation, and i-th of timestamp is not n-th of timestamp, then i-th of timestamp is determined as the original time stamp
The 1st new timestamp in sequence, and is added by 1 and triggers the first acquisition module 11 by i and continues to obtain in original time stamp sequence
